Breast cancer shows a unique spread pattern, often affecting bone, liver, lung, and brain. Breast cancer can be categorized into various subtypes according to gene expression patterns, and these subtypes exhibit specific preferences for organs where metastasis occurs. Breast tumors with luminal characteristics have a preference for spreading to the bone, whereas basal-like breast cancer (BLBC) shows a tendency to metastasize to the lungs. Still, the mechanisms behind this particular pattern of metastasis in organs have yet to be fully understood. In this evaluation, we will outline the latest progress in molecular signaling pathways and treatment methods for breast cancer lung metastasis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lung%20cancer" title="lung cancer">lung cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20cancer" title=" liver cancer"> liver cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=BLBC" title=" BLBC"> BLBC</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a> </p> <a href="https://publications.waset.org/abstracts/185132/metastasis-of-breast-cancer-to-the-lungs-implications-of-molecular-biology-and-treatment-options" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185132.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">48</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">158</span> Risk Association of RANKL and OPG Gene Polymorphism with Breast to Bone Metastasis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Najeeb%20Ullah%20Khan">Najeeb Ullah Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The receptor activator NF-κβ ligand (RANKL) and Osteoprotegerin (OPG) polymorphisms have been associated with the progression of breast cancer to bone metastasis. Here, we aimed to investigate the association of RANKL and OPG gene polymorphism with breast to bone metastasis in the Pashtun population, Pakistan. Methods: Genomic DNA was obtained from all the study subjects (106 breast cancer, 58 breast to bone metastasis, and 51 healthy controls). RANKL (rs9533156) and OPG (rs2073618, rs3102735) polymorphisms were genotyped using Tetra-ARMS PCR. Results: Our results indicated that the frequencies of OPG (rs3102735) risk allele and genotypes carrying risk allele in breast cancer vs healthy control (C- p=0.005; CC- p=0.0208; TC- p=0.0181), bone metastasis vs healthy control (C- p=0.0211; CC- p=0.0153; TC- p=0.0775), and breast cancer vs breast to bone metastasis (C- p=0.0001; CC- p=0.0001; TC- p=0.001) were found significantly associated with disease risk. However, there was no significant association observed for OPG (rs2073618) risk allele and risk allele containing genotypes in all study groups. Similarly, RANKL (rs9533156) risk alleles and corresponding genotypes in breast cancer vs healthy control (C- p=0.0001; CC- p=0.0001; TC- p=0.0084), bone metastasis vs healthy control (C- p=0.0001; CC- p=0.0001; TC- p=0.5593), and breast cancer vs breast to bone metastasis (C- p=0.0185; CC- p=0.6077; TC- p=0.1436) showed significant association except for the risk allele carrying genotypes in breast cancer to bone metastasis (TC, p=0.1436; CC, p=0.6077). Conclusion: OPG (rs3102735) and RANKL (rs9533156) showed significant association with breast to bone metastasis, while OPG (rs2073618) didn’t show a significant association with breast to bone metastasis in Pashtun population of Pakistan. However, more investigation will be required to disseminate the results while gene sequencing or whole-exome sequencing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20metastasis" title=" bone metastasis"> bone metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=OPG" title=" OPG"> OPG</a>, <a href="https://publications.waset.org/abstracts/search?q=RANKL" title=" RANKL"> RANKL</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphism" title=" polymorphism"> polymorphism</a> </p> <a href="https://publications.waset.org/abstracts/140839/risk-association-of-rankl-and-opg-gene-polymorphism-with-breast-to-bone-metastasis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140839.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">191</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">157</span> Gall Bladder Polyp Identified as Solitary RCC Metastasis 4 Years after Nephrectomy: An Unusual Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerard%20Bray">Gerard Bray</a>, <a href="https://publications.waset.org/abstracts/search?q=Arya%20Bahadori"> Arya Bahadori</a>, <a href="https://publications.waset.org/abstracts/search?q=Sachinka%20Ranasinghe"> Sachinka Ranasinghe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Renal cell carcinoma (RCC) is among the top 10 most common cancers worldwide, where metastatic disease carries a poor prognosis. Herein, we present a 74-year-old male presenting with asymptomatic solitary metachronous metastasis to the gall bladder 4 years following nephrectomy for clear cell RCC. Solitary RCC metastasis to the gall bladder following nephrectomy is rarely reported in the literature and brings with it a clinical conundrum of whether surgical resection or systemic therapy should be utilized. In this case, surgical excision with cholecystectomy was employed without systemic therapy. We, therefore, contribute a rare and interesting case that highlights that metastasectomy of a solitary metastasis can improve survival according to current literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=renal%20cell%20carcinoma" title="renal cell carcinoma">renal cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=gall%20bladder%20metastasis" title=" gall bladder metastasis"> gall bladder metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=solitary%20metastasectomy" title=" solitary metastasectomy"> solitary metastasectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=metachronous" title=" metachronous"> metachronous</a> </p> <a href="https://publications.waset.org/abstracts/145137/gall-bladder-polyp-identified-as-solitary-rcc-metastasis-4-years-after-nephrectomy-an-unusual-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145137.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">173</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">156</span> Gene Expression Profile Reveals Breast Cancer Proliferation and Metastasis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nandhana%20Vivek">Nandhana Vivek</a>, <a href="https://publications.waset.org/abstracts/search?q=Bhaskar%20Gogoi"> Bhaskar Gogoi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayyavu%20Mahesh"> Ayyavu Mahesh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Breast cancer metastasis plays a key role in cancer progression and fatality. The present study examines the potential causes of metastasis in breast cancer by investigating the novel interactions between genes and their pathways. The gene expression profile of GSE99394, GSE1246464, and GSE103865 was downloaded from the GEO data repository to analyze the differentially expressed genes (DEGs). Protein-protein interactions, target factor interactions, pathways and gene relationships, and functional enrichment networks were investigated. The proliferation pathway was shown to be highly expressed in breast cancer progression and metastasis in all three datasets. Gene Ontology analysis revealed 11 DEGs as gene targets to control breast cancer metastasis: LYN, DLGAP5, CXCR4, CDC6, NANOG, IFI30, TXP2, AGTR1, MKI67, and FTH1. Upon studying the function, genomic and proteomic data, and pathway involvement of the target genes, DLGAP5 proved to be a promising candidate due to it being highly differentially expressed in all datasets. The study takes a unique perspective on the avenues through which DLGAP5 promotes metastasis. The current investigation helps pave the way in understanding the role DLGAP5 plays in metastasis, which leads to an increased incidence of death among breast cancer patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genomics" title="genomics">genomics</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=microarray" title=" microarray"> microarray</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a> </p> <a href="https://publications.waset.org/abstracts/155120/gene-expression-profile-reveals-breast-cancer-proliferation-and-metastasis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155120.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">97</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">155</span> Management of Gastrointestinal Metastasis of Invasive Lobular Carcinoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sally%20Shepherd">Sally Shepherd</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20De%20Boer"> Richard De Boer</a>, <a href="https://publications.waset.org/abstracts/search?q=Craig%20Murphy"> Craig Murphy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Invasive lobular carcinoma (ILC) can metastasize to atypical sites within the peritoneal cavity, gastrointestinal, or genitourinary tract. Management varies depending on the symptom presentation, extent of disease burden, particularly if the primary disease is occult, and patient wishes. Case Series: 6 patients presented with general surgical presentations of ILC, including incomplete large bowel obstruction, cholecystitis, persistent lower abdominal pain, and faecal incontinence. 3 were diagnosed with their primary and metastatic disease in the same presentation, whilst 3 patients developed metastasis from 5 to 8 years post primary diagnosis of ILC. Management included resection of the metastasis (laparoscopic cholecystectomy), excision of the primary (mastectomy and axillary clearance), followed by a combination of aromatase inhibitors, biologic therapy, and chemotherapy. Survival post diagnosis of metastasis ranged from 3 weeks to 7 years. Conclusion: Metastatic ILC must be considered with any gastrointestinal or genitourinary symptoms in patients with a current or past history of ILC. Management may not be straightforward to chemotherapy if the acute pathology is resulting in a surgically resectable disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=gastrointestinal%20metastasis" title=" gastrointestinal metastasis"> gastrointestinal metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=invasive%20lobular%20carcinoma" title=" invasive lobular carcinoma"> invasive lobular carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a> </p> <a href="https://publications.waset.org/abstracts/131926/management-of-gastrointestinal-metastasis-of-invasive-lobular-carcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131926.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">154</span> Structural Protein-Protein Interactions Network of Breast Cancer Lung and Brain Metastasis Corroborates Conformational Changes of Proteins Lead to Different Signaling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farideh%20Halakou">Farideh Halakou</a>, <a href="https://publications.waset.org/abstracts/search?q=Emel%20Sen"> Emel Sen</a>, <a href="https://publications.waset.org/abstracts/search?q=Attila%20Gursoy"> Attila Gursoy</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozlem%20Keskin"> Ozlem Keskin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Protein–Protein Interactions (PPIs) mediate major biological processes in living cells. The study of PPIs as networks and analyze the network properties contribute to the identification of genes and proteins associated with diseases. In this study, we have created the sub-networks of brain and lung metastasis from primary tumor in breast cancer. To do so, we used seed genes known to cause metastasis, and produced their interactions through a network-topology based prioritization method named GUILDify. In order to have the experimental support for the sub-networks, we further curated them using STRING database. We proceeded by modeling structures for the interactions lacking complex forms in Protein Data Bank (PDB). The functional enrichment analysis shows that KEGG pathways associated with the immune system and infectious diseases, particularly the chemokine signaling pathway, are important for lung metastasis. On the other hand, pathways related to genetic information processing are more involved in brain metastasis. The structural analyses of the sub-networks vividly demonstrated their difference in terms of using specific interfaces in lung and brain metastasis. Furthermore, the topological analysis identified genes such as RPL5, MMP2, CCR5 and DPP4, which are already known to be associated with lung or brain metastasis. Additionally, we found 6 and 9 putative genes that are specific for lung and brain metastasis, respectively. Our analysis suggests that variations in genes and pathways contributing to these different breast metastasis types may arise due to change in tissue microenvironment. To show the benefits of using structural PPI networks instead of traditional node and edge presentation, we inspect two case studies showing the mutual exclusiveness of interactions and effects of mutations on protein conformation which lead to different signaling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=PPI%20networks" title=" PPI networks"> PPI networks</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20conformational%20changes" title=" protein conformational changes"> protein conformational changes</a> </p> <a href="https://publications.waset.org/abstracts/51346/structural-protein-protein-interactions-network-of-breast-cancer-lung-and-brain-metastasis-corroborates-conformational-changes-of-proteins-lead-to-different-signaling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51346.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">244</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">153</span> Recurrence of Papillary Thyroid Cancer with an Interval of 40 Years.

Therefore searching for a compound that could inhibit cancer metastasis is necessary. 13-Butoxyberberine bromide is a berberine derivative that has not been reported an anti-metastatic effect on skin cancer cells. This study aimed to investigate the anti-metastatic effect of 13-butoxyberberine bromide on skin cancer A431 cells. The effect of 13-butoxyberberine bromide on A431 cell viability was examined by MTT assay. Suppression of cell migration and invasion in A431 cells were determined by wound healing assay, transwell migration assay, and transwell invasion assay. Metastasis proteins were determined by western blotting. The results demonstrated that 13-butoxyberberine bromide decreased A431 cell viability in a dose-dependent manner. In addition, sub-toxic concentrations of 13-butoxyberberine bromide suppressed cell migration and invasion in A431 cells. In addition, 13-butoxyberberine bromide showed anti-metastatic effects by down-regulated MMP-2 and MMP-9 expression. These findings may be useful in the development of 13-butoxyberberine bromide as an anti-metastatic drug in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=13-butoxyberberine%20bromide" title="13-butoxyberberine bromide">13-butoxyberberine bromide</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20cancer" title=" skin cancer"> skin cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=MMP" title=" MMP"> MMP</a> </p> <a href="https://publications.waset.org/abstracts/158142/inhibitory-effect-of-13-butoxyberberine-bromide-on-metastasis-of-skin-cancer-a431-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158142.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">104</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">151</span> Effect of Total Body Irradiation for Metastatic Lymph Node and Lung Metastasis in Early Stage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shouta%20Sora">Shouta Sora</a>, <a href="https://publications.waset.org/abstracts/search?q=Shizuki%20Kuriu"> Shizuki Kuriu</a>, <a href="https://publications.waset.org/abstracts/search?q=Radhika%20Mishra"> Radhika Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=Ariunbuyan%20Sukhbaatar"> Ariunbuyan Sukhbaatar</a>, <a href="https://publications.waset.org/abstracts/search?q=Maya%20Sakamoto"> Maya Sakamoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Shiro%20Mori"> Shiro Mori</a>, <a href="https://publications.waset.org/abstracts/search?q=Tetsuya%20Kodama"> Tetsuya Kodama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lymph node (LN) metastasis accounts for 20 - 30 % of all deaths in patients with head and neck cancer. Therefore, the control of metastatic lymph nodes (MLNs) is necessary to improve the life prognosis of patients with cancer. In a classical metastatic theory, tumor cells are thought to metastasize hematogenously through a bead-like network of lymph nodes. Recently, a lymph node-mediated hematogenous metastasis theory has been proposed, in which sentinel LNs are regarded as a source of distant metastasis. Therefore, the treatment of MLNs at the early stage is essential to prevent distant metastasis. Radiation therapy is one of the primary therapeutic modalities in cancer treatment. In addition, total body irradiation (TBI) has been reported to act as activation of natural killer cells and increase of infiltration of CD4+ T-cells to tumor tissues. However, the treatment effect of TBI for MLNs remains unclear. This study evaluated the possibilities of low-dose total body irradiation (L-TBI) and middle-dose total body irradiation (M-TBI) for the treatment of MLNs. Mouse breast cancer FM3A-Luc cells were injected into subiliac lymph node (SiLN) of MXH10/Mo/LPR mice to induce the metastasis to the proper axillary lymph node (PALN) and lung. Mice were irradiated for the whole body on 4 days after tumor injection. The L-TBI and M-TBI were defined as irradiations to the whole body at 0.2 Gy and 1.0 Gy, respectively. Tumor growth was evaluated by in vivo bioluminescence imaging system. In the non-irradiated group, tumor activities on SiLN and PALN significantly increased over time, and the metastasis to the lung from LNs was confirmed 28 days after tumor injection. The L-TBI led to a tumor growth delay in PALN but did not control tumor growth in SiLN and metastasis to the lung. In contrast, it was found that the M-TBI significantly delayed the tumor growth of both SiLN and PALN and controlled the distant metastasis to the lung compared with non-irradiated and L-TBI groups. These results suggest that the M-TBI is an effective treatment method for MLNs in the early stage and distant metastasis from lymph nodes via blood vessels connected with LNs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metastatic%20lymph%20node" title="metastatic lymph node">metastatic lymph node</a>, <a href="https://publications.waset.org/abstracts/search?q=lung%20metastasis" title=" lung metastasis"> lung metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20therapy" title=" radiation therapy"> radiation therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20body%20irradiation" title=" total body irradiation"> total body irradiation</a>, <a href="https://publications.waset.org/abstracts/search?q=lymphatic%20system" title=" lymphatic system"> lymphatic system</a> </p> <a href="https://publications.waset.org/abstracts/140077/effect-of-total-body-irradiation-for-metastatic-lymph-node-and-lung-metastasis-in-early-stage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140077.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">181</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">150</span> Breast Cancer Early Recognition, New Methods of Screening, and Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Heidary">Sahar Heidary</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Breast cancer is a main public common obstacle global.

It is further unusual for it to be a site of metastasis, whilst the primary malignancy remains occult. Case Report: A 63-year-old female with three months of altered bowel habits underwent a CT scan of the abdomen and pelvis, revealing a bulky uterus and left ovary, nonspecific colonic thickening, and diffuse peritoneal changes. She underwent colposcopy, which revealed a large endocervical polyp that was excised, revealing strongly hormone-positive metastatic invasive lobular breast cancer. She subsequently underwent a PET scan, which showed moderately diffuse activity in the cervix and left adnexa. Breast examination was unremarkable, and screening mammography, ultrasound, and MRI of the breast did not identify any lesions. Her blood tests revealed a Ca 15-3 of 934, CA-125 of 220, and CEA of 27. She was commenced on letrozole and ribociclib with an improvement in her symptoms. Conclusion: It is rare for occult breast cancer to be established and diagnosed by pelvic imaging and biopsy. Suspicion of uterine or cervical metastasis should be heightened in patients with an active or past history of breast cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=occult%20breast%20cancer" title="occult breast cancer">occult breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=cervical%20metastasis" title=" cervical metastasis"> cervical metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=invasive%20lobular%20carcinoma" title=" invasive lobular carcinoma"> invasive lobular carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a> </p> <a href="https://publications.waset.org/abstracts/131927/metastatic-invasive-lobular-cancer-presenting-as-a-cervical-polyp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131927.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">148</span> Differentiated Thyroid Cancer Presenting with Solitary Bony Metastases to the Frontal Bone of the Skull</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christy%20M.%20Moen">Christy M.

A literature review found only six cases of thyroid cancer that metastasised to the frontal bone, with two of those involving further bone sites. Case Report: The patient was originally referred to the Oral and Maxillofacial Surgery team with an isolated mass on her forehead. Biopsies were performed, which showed this was likely a metastatic deposit from thyroid cancer. CT-PET scan showed this was an isolated lesion. The patient had a total thyroidectomy, and the forehead lesion was managed with radiotherapy. On interval scanning, the patient’s bony lesion had increased in size and had new lung nodules, which likely represented further metastasis. Conclusion: Isolated bony metastases to the frontal bone are rare. An important clinical principle to remember is that a bony metastasis from an unknown primary is more likely than primary bone cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer" title="cancer">cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=thyroid" title=" thyroid"> thyroid</a>, <a href="https://publications.waset.org/abstracts/search?q=head%20and%20neck" title=" head and neck"> head and neck</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a> </p> <a href="https://publications.waset.org/abstracts/138043/differentiated-thyroid-cancer-presenting-with-solitary-bony-metastases-to-the-frontal-bone-of-the-skull" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138043.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">212</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">147</span> Ring FingerPortein 2 (RNF2) Targeting by miRNAs in Breast Cancer Cell Lines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ceyda%20Okudu">Ceyda Okudu</a>, <a href="https://publications.waset.org/abstracts/search?q=Secil%20Eroglu"> Secil Eroglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Khandakar%20A.%20S.%20M.%20Saadat"> Khandakar A.

Balci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ring Finger Protein 2 (RNF2) is a member of polycomb repressive complex 1 (PRC1), which is one of the epigenetic regulators in the genome. When RNF2 combines with other PRC1 members, it mediates the mono-ubiquitination of Histon2A (H2A). In breast cancer, RNF2 is commonly overexpressed, and also it promotes metastasis and invasion in other aggressive tumors like melanoma, prostate, and hepatocarcinoma. The role of RNF2 in the metastasis and invasion of breast cancer has not yet been elucidated. Our aim is to observe the role of RNF2 in metastasis and invasion in this study by miRNA mediated RNF2 gene silencing in breast cancer cell lines. We selected miRNAs, targeting to RNF2 by searching online databases. miR-17-5p, miR20a-5p, and miR-106b-5p were transfected to breast cancer cell lines (MCF-7, MDA-MB-231, SK-BR-3, and ZR-75-1), and also we used normal breast epithelial cell line (hTERT-HME1) to compare RNF2 gene expression level. After 48-72 hours post-transfection, mRNAs were isolated from the cells, and gene expressions were measured by RT-qPCR after from cDNA syntheses. We observed that RNF2 was highly expressed in SK-BR-3 and MDA-MB-231 cell lines opposite to MCF-7 and ZR-75-1 cell lines. RNF2 was downregulated 5, 5 and 7 fold by miR17-5p, miR20a-5p and miR106b-5p respectively in MCF-7. However, in SK-BR-3 and ZR-75-1 cell lines, miRNAs did not affect significantly RNF2 gene expression level. miR20a-5p decreased RNF2 3 fold and miR17-5p and miR106b-5p did not affect MDA-MB-231. After gene expression analysis, we performed metastasis and invasion assay in MCF-7 cells. For metastasis, we used both wound healing assay and Transwell Cell Migration Assay, and we used Transwell Cell Invasion Assay for invasion. The data of this assay showed that miR17-5p and miR20a-5p decreased both invasion and metastasis level, but miR106b-5p has no effect. We would like to conclude that RNF2 can be targeted by miR17-5p, miR20a-5p and miR106b-5p in MCF-7 cells and also RNF2, which is one of the upregulated genes in aggressive tumor, can be decreased by using these miRNAs. In future, we would like to confirm these results at the protein level and also whether these miRNAs are direct target of RNF2 or not. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=epigenetic" title=" epigenetic"> epigenetic</a>, <a href="https://publications.waset.org/abstracts/search?q=microRNAs" title=" microRNAs"> microRNAs</a>, <a href="https://publications.waset.org/abstracts/search?q=RNF2" title=" RNF2"> RNF2</a> </p> <a href="https://publications.waset.org/abstracts/88136/ring-fingerportein-2-rnf2-targeting-by-mirnas-in-breast-cancer-cell-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88136.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">180</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">146</span> Oncogenic Role of MicroRNA-346 in Human Non-Small Cell Lung Cancer by Regulation of XPC/ERK/Snail/E-Cadherin Pathway</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cheng-Cao%20Sun">Cheng-Cao Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Shu-Jun%20Li"> Shu-Jun Li</a>, <a href="https://publications.waset.org/abstracts/search?q=De-Jia%20Li"> De-Jia Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Determinants of growth and metastasis in cancer remain of great interest to define. MicroRNAs (miRNAs) have frequently emerged as tumor metastatic regulator by acting on multiple signaling pathways. Here, we report the definition of miR-346 as an oncogenic microRNA that facilitates non-small cell lung cancer (NSCLC) cell growth and metastasis. XPC, an important DNA damage recognition factor in nucleotide excision repair was defined as a target for down-regulation by miR-346, functioning through direct interaction with the 3'-UTR of XPC mRNA. Blocking miR-346 by an antagomiR was sufficient to inhibit NSCLC cell growth and metastasis, an effect that could be phenol-copied by RNAi-mediated silencing of XPC. In vivo studies established that miR-346 overexpression was sufficient to promote tumor growth by A549 cells in xenografts mice, relative to control cells. Overall, our results defined miR-346 as an oncogenic miRNA in NSCLC, the levels of which contributed to tumor growth and invasive aggressiveness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microRNA-346" title="microRNA-346">microRNA-346</a>, <a href="https://publications.waset.org/abstracts/search?q=miR-346" title=" miR-346"> miR-346</a>, <a href="https://publications.waset.org/abstracts/search?q=XPC" title=" XPC"> XPC</a>, <a href="https://publications.waset.org/abstracts/search?q=non-small%20cell%20lung%20cancer" title=" non-small cell lung cancer"> non-small cell lung cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=oncogenesis" title=" oncogenesis"> oncogenesis</a> </p> <a href="https://publications.waset.org/abstracts/54942/oncogenic-role-of-microrna-346-in-human-non-small-cell-lung-cancer-by-regulation-of-xpcerksnaile-cadherin-pathway" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54942.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">312</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">145</span> Clinical Value of 18F-FDG-PET Compared with CT Scan in the Detection of Nodal and Distant Metastasis in Urothelial Carcinoma or Bladder Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Al-Zubaidi">Mohammed Al-Zubaidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Katherine%20Ong"> Katherine Ong</a>, <a href="https://publications.waset.org/abstracts/search?q=Pravin%20Viswambaram"> Pravin Viswambaram</a>, <a href="https://publications.waset.org/abstracts/search?q=Steve%20McCombie"> Steve McCombie</a>, <a href="https://publications.waset.org/abstracts/search?q=Oliver%20Oey"> Oliver Oey</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeremy%20Ong"> Jeremy Ong</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Gauci"> Richard Gauci</a>, <a href="https://publications.waset.org/abstracts/search?q=Ronny%20Low"> Ronny Low</a>, <a href="https://publications.waset.org/abstracts/search?q=Dickon%20Hayne"> Dickon Hayne</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Lymph node involvement along with distant metastasis in a patient with invasive bladder cancer determines the disease survival, therefeor, it is an essential determinant of the therapeutic management and outcome. This retrospective study aims to determine the accuracy of FDG PET scan in detecting lymphatic involvement and distant metastatic urothelial cancer compared to conventional CT staging. Method: A retrospective review of 76 patients with UC or BC who underwent surgery or confirmatory biopsy that was staged with both CT and 18F-FDG-PET (up to 8 weeks apart) between 2015 and 2020. Fifty-sevenpatients (75%) had formal pelvic LN dissection or biopsy of suspicious metastasis. 18F-FDG-PET reports for positive sites were qualitative depending on SUV Max. On the other hand, enlarged LN by RECIST criteria 1.1 (>10 mm) and other qualitative findings suggesting metastasis were considered positive in CT scan. Histopathological findings from surgical specimens or image-guided biopsies were considered the gold standard in comparison to imaging reports. 18F-FDG-avid or enlarged pelvic LNs with surgically proven nodal metastasis were considered true positives. Performance characteristics of 18F-FDG-PET and CT, including sensitivity, specificity, positive predictive value (PPV), and negative predictive value (PPV), were calculated. Results: Pelvic LN involvement was confirmed histologically in 10/57 (17.5%) patients. Sensitivity, specificity, PPV and NPV of CT for detecting pelvic LN metastases were 41.17% (95% CI:18-67%), 100% (95% CI:90-100%) 100% (95% CI:59-100%) and 78.26% (95% CI:64-89%) respectively. Sensitivity, specificity, PPV and NPV of 18F-FDG-PET for detecting pelvic LN metastases were 62.5% (95% CI:35-85%), 83.78% (95% CI:68-94%), 62.5% (95% CI:35-85%), and 83.78% (95% CI:68-94%) respectively. Pre-operative staging with 18F-FDG-PET identified the distant metastatic disease in 9/76 (11.8%) patients who were occult on CT. This retrospective study suggested that 18F-FDG-PET may be more sensitive than CT for detecting pelvic LN metastases. 7/76 (9.2%) patients avoided cystectomy due to 18F-FDG-PET diagnosed metastases that were not reported on CT. Conclusion: 18F-FDG-PET is more sensitive than CT for pelvic LN metastases, which can be used as the standard modality of bladder cancer staging, as it may change the treatment by detecting lymph node metastasis that was occult in CT. Further research involving randomised controlled trials comparing the diagnostic yield of 18F-FDG-PET and CT in detecting nodal and distant metastasis in UC or BC is warranted to confirm our findings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FDG%20PET" title="FDG PET">FDG PET</a>, <a href="https://publications.waset.org/abstracts/search?q=CT%20scan" title=" CT scan"> CT scan</a>, <a href="https://publications.waset.org/abstracts/search?q=urothelial%20cancer" title=" urothelial cancer"> urothelial cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=bladder%20cancer" title=" bladder cancer"> bladder cancer</a> </p> <a href="https://publications.waset.org/abstracts/154697/clinical-value-of-18f-fdg-pet-compared-with-ct-scan-in-the-detection-of-nodal-and-distant-metastasis-in-urothelial-carcinoma-or-bladder-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154697.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">121</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">144</span> The Role Of Diallyl Trisulﬁde As A Suppressor In Activated-Platelets Induced Human Breast Cancer MDA-MB-435s Cells Hematogenous Metastasis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuping%20Liu">Yuping Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Tao"> Li Tao</a>, <a href="https://publications.waset.org/abstracts/search?q=Yin%20Lu"> Yin Lu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Accumulating evidence has been shown that diallyl trisulﬁde (DATS) from garlic may reduce the risk of developing several types of cancer. In view of the dynamic crosstalk interplayed by tumor cells and platelets in hematogenous metastasis, we demonstrate the effectiveness of DATS on the metastatic behaviors of MDA-MB-435s human breast cancer cell line co-incubated with activated platelets. Indeed, our data identified that DATS significantly blocked platelets fouction induced by PAF, followed by the decreased production of TXB2. DATS was found to dose-dependently suppressed MDA-MB-435s cell migration and invasion in presence of activated platelets by PAF in vitro. Furthermore, the expression, secretion and enzymatic activity of matrix metalloproteinase (MMP)-2/9, as well as the luciferase activity of upstream regulator NF-κB in MDA-MB-435s, were obviously diminished by DATS. In parallel, DATS blocked upstream NF-κB activation signaling complexes composed of extracellular signal-related kinase (ERK) as assessed by measuring the levels of the phosphorylated forms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DATS" title="DATS">DATS</a>, <a href="https://publications.waset.org/abstracts/search?q=ERK" title=" ERK"> ERK</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=MMPs" title=" MMPs"> MMPs</a>, <a href="https://publications.waset.org/abstracts/search?q=NF-%CE%BAB" title=" NF-κB"> NF-κB</a>, <a href="https://publications.waset.org/abstracts/search?q=platelet" title=" platelet"> platelet</a> </p> <a href="https://publications.waset.org/abstracts/2843/the-role-of-diallyl-trisulfide-as-a-suppressor-in-activated-platelets-induced-human-breast-cancer-mda-mb-435s-cells-hematogenous-metastasis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2843.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">386</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">143</span> Molecular Portraits: The Role of Posttranslational Modification in Cancer Metastasis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Navkiran%20Kaur">Navkiran Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=Apoorva%20Mathur"> Apoorva Mathur</a>, <a href="https://publications.waset.org/abstracts/search?q=Abhishree%20Agarwal"> Abhishree Agarwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Sakshi%20Gupta"> Sakshi Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Tuhin%20Rashmi"> Tuhin Rashmi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim: Breast cancer is the most common cancer in women worldwide, and resistance to the current therapeutics, often concurrently, is an increasing clinical challenge. Glycosylation of proteins is one of the most important post-translational modifications. It is widely known that aberrant glycosylation has been implicated in many different diseases due to changes associated with biological function and protein folding. Alterations in cell surface glycosylation, can promote invasive behavior of tumor cells that ultimately lead to the progression of cancer. In breast cancer, there is an increasing evidence pertaining to the role of glycosylation in tumor formation and metastasis. In the present study, an attempt has been made to study the disease associated sialoglycoproteins in breast cancer by using bioinformatics tools. The sequence will be retrieved from UniProt database. A database in the form of a word document was made by a collection of FASTA sequences of breast cancer gene sequence. Glycosylation was studied using yinOyang tool on ExPASy and Differential genes expression and protein analysis was done in context of breast cancer metastasis. The number of residues predicted O-glc NAc threshold containing 50 aberrant glycosylation sites or more was detected and recorded for individual sequence. We found that the there is a significant change in the expression profiling of glycosylation patterns of various proteins associated with breast cancer. Differential aberrant glycosylated proteins in breast cancer cells with respect to non-neoplastic cells are an important factor for the overall progression and development of cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=bioinformatics" title=" bioinformatics"> bioinformatics</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=glycosylation" title=" glycosylation"> glycosylation</a> </p> <a href="https://publications.waset.org/abstracts/68966/molecular-portraits-the-role-of-posttranslational-modification-in-cancer-metastasis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68966.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">294</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">142</span> Research on the Role of Platelet Derived Growth Factor Receptor Beta in Promoting Dedifferentiation and Pulmonary Metastasis of Osteosarcoma Under Hypoxic Microenvironment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enjie%20Xu">Enjie Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhen%20Huang"> Zhen Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kunpeng%20Zhu"> Kunpeng Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianping%20Hu"> Jianping Hu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaolong%20Ma"> Xiaolong Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongjie%20Wang"> Yongjie Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiazhuang%20Zhu"> Jiazhuang Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chunlin%20Zhang"> Chunlin Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Abstract: Hypoxia and dedifferentiation of osteosarcoma (OS) cells leads to poor prognosis. We plan to identify the role of hypoxia on dedifferentiation and the associated signaling pathways. We performed a sphere formation assay and determined spheroid cells as dedifferentiated cells by detecting stem cell-like markers. RNAi assay was used to explore the expression relationship between hypoxia inducible factor 1 subunit alpha (HIF1A) and platelet derived growth factor receptor beta (PDGFRB). We obtained PDGFRB knockdown and overexpression cells through lentiviral infection experiments and the effects of PDGFRB on cytoskeleton rearrangement and cell adhesion were explored by immunocytochemistry. Wound-healing experiments, transwell assays, and animal trials were employed to investigate the effect of PDGFRB on OS metastasis. Dedifferentiated OS cells were found to exhibit high expression of HIF1A and PDGFRB, and HIF1A promoted the expression of PDGFRB, subsequently activated ras homolog family member A (RhoA), and increased the phosphorylation of myosin light chain (MLC). PDGFRB also enhanced the phosphorylation of focal adhesion kinase (FAK). The OS cell morphology and vinculin distribution were altered by PDGFRB. PDGFRB also promoted cell dedifferentiation and had a significant impact on the metastasis of OS cells both in vitro and in vivo. Our results demonstrated that HIF1A up-regulated PDGFRB under hypoxic conditions, and PDGFRB regulated the actin cytoskeleton by activating RhoA and subsequently phosphorylating MLC, thereby promoting OS dedifferentiation and pulmonary metastasis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=osteosarcoma" title="osteosarcoma">osteosarcoma</a>, <a href="https://publications.waset.org/abstracts/search?q=dedifferentiation" title=" dedifferentiation"> dedifferentiation</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=cytoskeleton%20rearrangement" title=" cytoskeleton rearrangement"> cytoskeleton rearrangement</a>, <a href="https://publications.waset.org/abstracts/search?q=PDGFRB" title=" PDGFRB"> PDGFRB</a>, <a href="https://publications.waset.org/abstracts/search?q=hypoxia" title=" hypoxia"> hypoxia</a> </p> <a href="https://publications.waset.org/abstracts/184648/research-on-the-role-of-platelet-derived-growth-factor-receptor-beta-in-promoting-dedifferentiation-and-pulmonary-metastasis-of-osteosarcoma-under-hypoxic-microenvironment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184648.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">47</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">141</span> The Predictive Significance of Metastasis Associated in Colon Cancer-1 (MACC1) in Primary Breast Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jasminka%20Mujic">Jasminka Mujic</a>, <a href="https://publications.waset.org/abstracts/search?q=Karin%20Milde-Langosch"> Karin Milde-Langosch</a>, <a href="https://publications.waset.org/abstracts/search?q=Volkmar%20Mueller"> Volkmar Mueller</a>, <a href="https://publications.waset.org/abstracts/search?q=Mirza%20Suljagic"> Mirza Suljagic</a>, <a href="https://publications.waset.org/abstracts/search?q=Tea%20Becirevic"> Tea Becirevic</a>, <a href="https://publications.waset.org/abstracts/search?q=Jozo%20Coric"> Jozo Coric</a>, <a href="https://publications.waset.org/abstracts/search?q=Daria%20Ler"> Daria Ler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> MACC1 (metastasis associated in colon cancer-1) is a prognostic biomarker for tumor progression, metastasis, and survival of a variety of solid cancers. MACC1 also causes tumor growth in xenograft models and acts as a master regulator of the HGF/MET signaling pathway. In breast cancer, the expression of MACC1 determined by immunohistochemistry was significantly associated with positive lymph node status and advanced clinical stage. The aim of the present study was to further investigate the prognostic or predictive value of MACC1 expression in breast cancer using western blot analysis and immunohistochemistry. The results of our study have shown that high MACC1 expression in breast cancer is associated with shorter disease-free survival, especially in node-negative tumors. The MACC1 might be a suitable biomarker to select patients with a higher probability of recurrence which might benefit from adjuvant chemotherapy. Our results support a biologic role and potentially open the perspective for the use of MACC1 as predictive biomarker for treatment decision in breast cancer patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarker" title=" biomarker"> biomarker</a>, <a href="https://publications.waset.org/abstracts/search?q=HGF%2FMET" title=" HGF/MET"> HGF/MET</a>, <a href="https://publications.waset.org/abstracts/search?q=MACC1" title=" MACC1"> MACC1</a> </p> <a href="https://publications.waset.org/abstracts/86514/the-predictive-significance-of-metastasis-associated-in-colon-cancer-1-macc1-in-primary-breast-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86514.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">233</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">140</span> Study on Co-Relation of Prostate Specific Antigen with Metastatic Bone Disease in Prostate Cancer on Skeletal Scintigraphy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Waleed%20Asfandyar">Muhammad Waleed Asfandyar</a>, <a href="https://publications.waset.org/abstracts/search?q=Akhtar%20Ahmed"> Akhtar Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Adib-ul-Hasan%20Rizvi"> Syed Adib-ul-Hasan Rizvi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To evaluate the ability of serum concentration of prostate specific antigen between two cutting points considering it as a predictor of skeletal metastasis on bone scintigraphy in men with prostate cancer. Settings: This study was carried out in department of Nuclear Medicine at Sindh Institute of Urology and Transplantation (SIUT) Karachi, Pakistan. Materials and Method: From August 2013 to November 2013, forty two (42) consecutive patients with prostate cancer who underwent technetium-99m methylene diphosphonate (Tc-99mMDP) whole body bone scintigraphy were prospectively analyzed. The information was collected from the scintigraphic database at a Nuclear medicine department Sindh institute of urology and transplantation Karachi Pakistan. Patients who did not have a serum PSA concentration available within 1 month before or after the time of performing the Tc-99m MDP whole body bone scintigraphy were excluded from this study. A whole body bone scintigraphy scan (from the toes to top of the head) was performed using a whole-body Moving gamma camera technique (anterior and posterior) 2–4 hours after intravenous injection of 20 mCi of Tc-99m MDP. In addition, all patients necessarily have a pathological report available. Bony metastases were determined from the bone scan studies and no further correlation with histopathology or other imaging modalities were performed. To preserve patient confidentiality, direct patient identifiers were not collected. In all the patients, Prostate specific antigen values and skeletal scintigraphy were evaluated. Results: The mean age, mean PSA, and incidence of bone metastasis on bone scintigraphy were 68.35 years, 370.51 ng/mL and 19/42 (45.23%) respectively. According to PSA levels, patients were divided into 5 groups < 10ng/mL (10/42), 10-20 ng/mL (5/42), 20-50 ng/mL (2/42), 50-100 (3/42), 100- 500ng/mL (3/42) and more than 500ng/mL (0/42) presenting negative bone scan. The incidence of positive bone scan (%) for bone metastasis for each group were O1 patient (5.26%), 0%, 03 patients (15.78%), 01 patient (5.26%), 04 patients (21.05%), and 10 patients (52.63%) respectively. From the 42 patients 19 (45.23%) presented positive scintigraphic examination for the presence of bone metastasis. 1 patient presented bone metastasis on bone scintigraphy having PSA level less than 10ng/mL, and in only 1 patient (5.26%) with bone metastasis PSA concentration was less than 20 ng/mL. therefore, when the cutting point adopted for PSA serum concentration was 10ng/mL, a negative predictive value for bone metastasis was 95% with sensitivity rates 94.74% and the positive predictive value and specificities of the method were 56.53% and 43.48% respectively. When the cutting point of PSA serum concentration was 20ng/mL the observed results for Positive predictive value and specificity were (78.27% and 65.22% respectively) whereas negative predictive value and sensitivity stood (100% and 95%) respectively. Conclusion: Results of our study allow us to conclude that serum PSA concentration of higher than 20ng/mL was the most accurate cutting point than a serum concentration of PSA higher than 10ng/mL to predict metastasis in radionuclide bone scintigraphy. In this way, unnecessary cost can be avoided, since a considerable part of prostate adenocarcinomas present low serum PSA levels less than 20 ng/mL and for these cases radionuclide bone scintigraphy could be unnecessary. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20scan" title="bone scan">bone scan</a>, <a href="https://publications.waset.org/abstracts/search?q=cut%20off%20value" title=" cut off value"> cut off value</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate%20specific%20antigen%20value" title=" prostate specific antigen value"> prostate specific antigen value</a>, <a href="https://publications.waset.org/abstracts/search?q=scintigraphy" title=" scintigraphy"> scintigraphy</a> </p> <a href="https://publications.waset.org/abstracts/43614/study-on-co-relation-of-prostate-specific-antigen-with-metastatic-bone-disease-in-prostate-cancer-on-skeletal-scintigraphy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43614.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">319</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">139</span> Aza-Flavanones as Small Molecule Inhibitors of MicroRNA-10b in MDA-MB-231 Breast Cancer Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debasmita%20Mukhopadhyay">Debasmita Mukhopadhyay</a>, <a href="https://publications.waset.org/abstracts/search?q=Manika%20Pal%20Bhadra"> Manika Pal Bhadra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> MiRNAs contribute to oncogenesis either as tumor suppressors or oncogenes. Hence, discovery of miRNA-based therapeutics are imperative to ameliorate cancer. Modulation of miRNA maturation is accomplished via several therapeutic agents, including small molecules and oligonucleotides. Due to the attractive pharmacokinetic properties of small molecules over oligonucleotides, we set to identify small molecule inhibitors of a metastasis-inducing microRNA. Cytotoxicity profile of aza-flavanone C1 was analyzed in a panel of breast cancer cells employing the NCI-60 screen protocols. Flow cytometry, immunofluorescence and western blotting of apoptotic or EMT markers were performed to analyze the effect of C1. A dual luciferase assay unequivocally suggested that C1 repressed endogenous miR-10b in MDA-MB-231 cells. A derivative of aza-flavanone C1 is shown as a strong inhibitor miR-10b. Blockade of miR-10b by C1 resulted in decreased expression of miR-10b targets in an aggressive breast cancer cell line model, MDA-MB-231. Abrogation of TWIST1, an EMT-inducing transcription factor also contributed to C1 mediated apoptosis. Moreover C1 exhibited a specific and selective down-regulation of miR-10b and did not function as a general inhibitor of miRNA biogenesis or other oncomiRs of breast carcinoma. Aza-flavanone congener C1 functions as a potent inhibitor of the metastasis-inducing microRNA, miR-10b. Our present study provides evidence for targeting metastasis-inducing microRNA, miR-10b with a derivative of Aza-flavanone. Better pharmacokinetic properties of small molecules place them as attractive agents compared to nucleic acids based therapies to target miRNA. Further work, in generating analogues based on aza-flavanone moieties will significantly improve the affinity of the small molecules to bind miR-10b. Finally, it is imperative to develop small molecules as novel miRNA-therapeutics in the fight against cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=microRNA" title=" microRNA"> microRNA</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=EMT" title=" EMT "> EMT </a> </p> <a href="https://publications.waset.org/abstracts/23183/aza-flavanones-as-small-molecule-inhibitors-of-microrna-10b-in-mda-mb-231-breast-cancer-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23183.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">565</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">138</span> Numerical Simulation of a Single Cell Passing through a Narrow Slit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lanlan%20Xiao">Lanlan Xiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Liu"> Yang Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuo%20Chen"> Shuo Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Bingmei%20Fu"> Bingmei Fu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most cancer-related deaths are due to metastasis. Metastasis is a complex, multistep processes including the detachment of cancer cells from the primary tumor and the migration to distant targeted organs through blood and/or lymphatic circulations. During hematogenous metastasis, the emigration of tumor cells from the blood stream through the vascular wall into the tissue involves arrest in the microvasculature, adhesion to the endothelial cells forming the microvessel wall and transmigration to the tissue through the endothelial barrier termed as extravasation. The narrow slit between endothelial cells that line the microvessel wall is the principal pathway for tumor cell extravasation to the surrounding tissue. To understand this crucial step for tumor hematogenous metastasis, we used Dissipative Particle Dynamics method to investigate an individual cell passing through a narrow slit numerically. The cell membrane was simulated by a spring-based network model which can separate the internal cytoplasm and surrounding fluid. The effects of the cell elasticity, cell shape and cell surface area increase, and slit size on the cell transmigration through the slit were investigated. Under a fixed driven force, the cell with higher elasticity can be elongated more and pass faster through the slit. When the slit width decreases to 2/3 of the cell diameter, the spherical cell becomes jammed despite reducing its elasticity modulus by 10 times. However, transforming the cell from a spherical to ellipsoidal shape and increasing the cell surface area only by 3% can enable the cell to pass the narrow slit. Therefore the cell shape and surface area increase play a more important role than the cell elasticity in cell passing through the narrow slit. In addition, the simulation results indicate that the cell migration velocity decreases during entry but increases during exit of the slit, which is qualitatively in agreement with the experimental observation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dissipative%20particle%20dynamics" title="dissipative particle dynamics">dissipative particle dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=deformability" title=" deformability"> deformability</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20area%20increase" title=" surface area increase"> surface area increase</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20migration" title=" cell migration"> cell migration</a> </p> <a href="https://publications.waset.org/abstracts/40189/numerical-simulation-of-a-single-cell-passing-through-a-narrow-slit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40189.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">334</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">137</span> Designed Purine Molecules and in-silico Evaluation of Aurora Kinase Inhibition in Breast Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pooja%20Kumari">Pooja Kumari</a>, <a href="https://publications.waset.org/abstracts/search?q=Anandkumar%20Tengli"> Anandkumar Tengli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aurora kinase enzyme, a protein on overexpression, leads to metastasis and is extremely important for women’s health in terms of prevention or treatment. While creating a targeted technique, the aim of the work is to design purine molecules that inhibit in aurora kinase enzyme and helps to suppress breast cancer. Purine molecules attached to an amino acid in DNA block protein synthesis or halt the replication and metastasis caused by the aurora kinase enzyme. Various protein related to the overexpression of aurora protein was docked with purine molecule using Biovia Drug Discovery, the perpetual software. Various parameters like X-ray crystallographic structure, presence of ligand, Ramachandran plot, resolution, etc., were taken into consideration for selecting the target protein. A higher negative binding scored molecule has been taken for simulation studies. According to the available research and computational analyses, purine compounds may be powerful enough to demonstrate a greater affinity for the aurora target. Despite being clinically effective now, purines were originally meant to fight breast cancer by inhibiting the aurora kinase enzyme. In in-silico studies, it is observed that purine compounds have a moderate to high potency compared to other molecules, and our research into the literature revealed that purine molecules have a lower risk of side effects. The research involves the design, synthesis, and identification of active purine molecules against breast cancer. Purines are structurally similar to the normal metabolites of adenine and guanine; hence interfere/compete with protein synthesis and suppress the abnormal proliferation of cells/tissues. As a result, purine target metastasis cells and stop the growth of kinase; purine derivatives bind with DNA and aurora protein which may stop the growth of protein or inhibits replication and stop metastasis of overexpressed aurora kinase enzyme. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aurora%20kinases" title="aurora kinases">aurora kinases</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20silico%20studies" title=" in silico studies"> in silico studies</a>, <a href="https://publications.waset.org/abstracts/search?q=medicinal%20chemistry" title=" medicinal chemistry"> medicinal chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=combination%20therapies" title=" combination therapies"> combination therapies</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20cancer" title=" chronic cancer"> chronic cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20translation" title=" clinical translation"> clinical translation</a> </p> <a href="https://publications.waset.org/abstracts/158245/designed-purine-molecules-and-in-silico-evaluation-of-aurora-kinase-inhibition-in-breast-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158245.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">86</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">136</span> Metastatic Polypoid Nodular Melanoma Management During The COVID-19 Pandemic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stefan%20Bradu">Stefan Bradu</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Siegel"> Daniel Siegel</a>, <a href="https://publications.waset.org/abstracts/search?q=Jameson%20Loyal"> Jameson Loyal</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Leaf"> Andrea Leaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Alana%20Kurtti"> Alana Kurtti</a>, <a href="https://publications.waset.org/abstracts/search?q=Usha%20Alapati"> Usha Alapati</a>, <a href="https://publications.waset.org/abstracts/search?q=Jared%20Jagdeo"> Jared Jagdeo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Compared with all other variants of nodular melanoma, patients with polypoid nodular melanoma have the lowest 5-year survival rate.

This report demonstrates the successful treatment of a rapidly developing red nodular polypoid melanoma with metastasis using surgery and adjuvant nivolumab in a SARS-CoV-2-positive patient who delayed seeking care due to the COVID-19 pandemic. In addition to detailing the successful treatment approach, the immunosuppressive effects of SARS-2-CoV and its possible contribution to the rapid progression of polypoid melanoma are discussed. This case highlights the complex challenges of melanoma diagnosis and management during the COVID-19 pandemic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=covid-19" title="covid-19">covid-19</a>, <a href="https://publications.waset.org/abstracts/search?q=dermatology" title=" dermatology"> dermatology</a>, <a href="https://publications.waset.org/abstracts/search?q=immunotherapy" title=" immunotherapy"> immunotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=melanoma" title=" melanoma"> melanoma</a>, <a href="https://publications.waset.org/abstracts/search?q=nivolumab" title=" nivolumab"> nivolumab</a> </p> <a href="https://publications.waset.org/abstracts/140542/metastatic-polypoid-nodular-melanoma-management-during-the-covid-19-pandemic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140542.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">209</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">135</span> Inhibitory Effect of P2Y1R Agonist 1-Indolinoalkyl 2-Phenolic Derivative on Prostate Cancer Cell Proliferation via the MAPK Signalling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hien%20Thi%20Thu%20Le">Hien Thi Thu Le</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuno%20Rafael%20Candeias"> Nuno Rafael Candeias</a>, <a href="https://publications.waset.org/abstracts/search?q=Olli%20Yli-Harja"> Olli Yli-Harja</a>, <a href="https://publications.waset.org/abstracts/search?q=Meenakshisundaram%20Kandhavelu"> Meenakshisundaram Kandhavelu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purinergic receptor 1 (P2Y1R) is the potential therapeutic target for inducing prostate cancer (PCa) cell death. Recently, 1-indolinoalkyl 2-phenolic derivative, HIC, was identified as a P2Y1R agonist that increases apoptosis and inhibits cell proliferation of PCa. However, the biological effects of HIC have not been extensively studied at the molecular level. In the present study, we have investigated the anticancer effects of HIC and the molecular mechanisms underlying in PCa cells. Half maximal inhibitory concentration (IC₅₀) of HIC was measured as 15.98 μM and 15.64 μM for DU145 and PC3 cells, respectively. In addition, we found that HIC inhibited cell growth and metastasis of PC3 and DU145 cells colonies, spheroid areas, and migrated cells. RNA seq analysis revealed significant changes of over 3000 genes (p value < 0.05) upon HIC treatment in PC3 and DU145 cells. Genes involved in DNA damage, apoptosis, cell cycle arrest at G1/S phase were modulated by HIC treatment. MAPK and NF-κB protein array revealed the increased expression of ERK1/2, JNK1/2, p53 phosphorylation, and p53 protein. ERK1/2 and JNK1/2 activations are known to increase the stabilization of p53, a tumor suppressor protein, which is required to arrest the cell cycle at G1/S phase and cause cell death of PCa cells. Overall, our results suggest that HIC can serve as a multi-dimensional chemotherapeutic agent possessing strong cytotoxic, anti-cancer, and anti-metastasis against PCa growth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prostate%20cancer" title="prostate cancer">prostate cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=P2Y1%20receptor" title=" P2Y1 receptor"> P2Y1 receptor</a>, <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title=" apoptosis"> apoptosis</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a> </p> <a href="https://publications.waset.org/abstracts/132678/inhibitory-effect-of-p2y1r-agonist-1-indolinoalkyl-2-phenolic-derivative-on-prostate-cancer-cell-proliferation-via-the-mapk-signalling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132678.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">133</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">134</span> Effects of a Bioactive Subfraction of Strobilanthes Crispus on the Tumour Growth, Body Weight and Haematological Parameters in 4T1-Induced Breast Cancer Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yusha%27u%20Shu%27aibu%20Baraya">Yusha'u Shu'aibu Baraya</a>, <a href="https://publications.waset.org/abstracts/search?q=Kah%20Keng%20%20Wong"> Kah Keng Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=Nik%20Soriani%20Yaacob"> Nik Soriani Yaacob</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Strobilanthes crispus (S. crispus), is a Malaysian herb locally known as ‘Pecah kaca’ or ‘Jin batu’ which have demonstrated potent anticancer effects in both in vitro and in vivo models. In particular, S. crispus subfraction (SCS) significantly reduced tumor growth in N-methyl-N-Nitrosourea-induced breast cancer rat model. However, there is paucity of information on the effects of SCS in breast cancer metastasis. Thus, in this study, the antimetastatic effects of SCS (100 mg/kg) was investigated following 30 days of treatment in 4T1-induced mammary tumor (n = 5) model. The response to treatment was assessed based on the outcome of the tumour growth, body weight and hematological parameters. The results demonstrated that tumor bearing mice treated with SCS (TM-S) had significant (p<0.05) reduction in the mean tumor number and tumor volume as well as tumor weight compared to the tumor bearing mice (TM), i.e. tumor untreated group. Also, there was no secondary tumor formation or tumor-associated lesions in the major organs of TM-S compared to the TM group. Similarly, comparable body weights were observed among the TM-S, normal (uninduced) mice treated with SCS and normal (untreated/control) mice (NM) groups compared to the TM group (p<0.05). Furthermore, SCS administration does not cause significant changes in the hematological parameters as compared to the NM group, which indicates no sign of anemia and toxicity related effects. In conclusion, SCS significantly inhibited the overall tumor growth and metastasis in 4T1-induced breast cancer mouse model suggesting its promising potentials as therapeutic agent for breast cancer treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=4T1-cells" title="4T1-cells">4T1-cells</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title=" breast cancer"> breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=Strobilanthes%20crispus" title=" Strobilanthes crispus "> Strobilanthes crispus </a> </p> <a href="https://publications.waset.org/abstracts/119710/effects-of-a-bioactive-subfraction-of-strobilanthes-crispus-on-the-tumour-growth-body-weight-and-haematological-parameters-in-4t1-induced-breast-cancer-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119710.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">133</span> Identification of Significant Genes in Rheumatoid Arthritis, Melanoma Metastasis, Ulcerative Colitis and Crohn’s Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krishna%20Pal%20Singh">Krishna Pal Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Shailendra%20Kumar%20Gupta"> Shailendra Kumar Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Olaf%20Wolkenhauer"> Olaf Wolkenhauer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Our study aimed to identify common genes and potential targets across the four diseases, which include rheumatoid arthritis, melanoma metastasis, ulcerative colitis, and Crohn’s disease. We used a network and systems biology approach to identify the hub gene, which can act as a potential target for all four disease conditions. The regulatory network was extracted from the PPI using the MCODE module present in Cytoscape. Our objective was to investigate the significance of hub genes in these diseases using gene ontology and KEGG pathway enrichment analysis. Methods: Our methodology involved collecting disease gene-related information from DisGeNET databases and performing protein-protein interaction (PPI) network and core genes screening. We then conducted gene ontology and KEGG pathway enrichment analysis. Results: We found that IL6 plays a critical role in all disease conditions and in different pathways that can be associated with the development of all four diseases. Conclusions: The theoretical importance of our research is that we employed various systems and structural biology techniques to identify a crucial protein that could serve as a promising target for treating multiple diseases. Our data collection and analysis procedures involved rigorous scrutiny, ensuring high-quality results. Our conclusion is that IL6 plays a significant role in all four diseases, and it can act as a potential target for treating them. Our findings may have important implications for the development of novel therapeutic interventions for these diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=melanoma%20metastasis" title="melanoma metastasis">melanoma metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=rheumatoid%20arthritis" title=" rheumatoid arthritis"> rheumatoid arthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammatory%20bowel%20diseases" title=" inflammatory bowel diseases"> inflammatory bowel diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20bioinformatics%20analysis" title=" integrated bioinformatics analysis"> integrated bioinformatics analysis</a> </p> <a href="https://publications.waset.org/abstracts/168255/identification-of-significant-genes-in-rheumatoid-arthritis-melanoma-metastasis-ulcerative-colitis-and-crohns-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168255.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">90</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">132</span> Hsa-miR-139-5p Acts as a Tumor Suppressor by Targeting C-Met in Non-Small Cell Lung Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chengcao%20Sun">Chengcao Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Shujun%20Li"> Shujun Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Cuili%20Yang"> Cuili Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongyong%20Xi"> Yongyong Xi</a>, <a href="https://publications.waset.org/abstracts/search?q=Liang%20Wang"> Liang Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Feng%20Zhang"> Feng Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Dejia%20Li"> Dejia Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hsa-miRNA-139-5p (miR-139-5p) has recently been discovered having anticancer efficacy in different organs. However, the role of miR-139-5p on lung cancer is still ambiguous. In this study, we investigated the role of miR-139-5p on development of lung cancer. Results indicated miR-139-5p was significantly down-regulated in primary tumor tissues and very low levels were found in a non-small cell lung cancer (NSCLC) cell lines. Ectopic expression of miR-139-5p in NSCLC cell lines significantly suppressed cell growth through inhibition of cyclin D1 and up-regulation of p57(Kip2). In addition, miR-139-5p induced apoptosis, as indicated by up-regulation of key apoptosis gene cleaved caspase-3, and down-regulation of anti-apoptosis gene Bcl2. Moreover, miR-139-5p inhibited cellular metastasis through inhibition of matrix metalloproteinases (MMP)-7 and MMP-9. Further, oncogene c-Met was revealed to be a putative target of miR-139-5p, which was inversely correlated with miR-139-5p expression. Taken together, our results demonstrated that miR-139-5p plays a pivotal role in lung cancer through inhibiting cell proliferation, metastasis, and promoting apoptosis by targeting oncogenic c-Met. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hsa-miRNA-139-5p%20%28miR-139-5p%29" title="hsa-miRNA-139-5p (miR-139-5p)">hsa-miRNA-139-5p (miR-139-5p)</a>, <a href="https://publications.waset.org/abstracts/search?q=c-Met" title=" c-Met"> c-Met</a>, <a href="https://publications.waset.org/abstracts/search?q=non-small%20cell%20lung%20cancer%20%28NSCLC%29" title=" non-small cell lung cancer (NSCLC)"> non-small cell lung cancer (NSCLC)</a>, <a href="https://publications.waset.org/abstracts/search?q=proliferation" title=" proliferation"> proliferation</a>, <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title=" apoptosis"> apoptosis</a> </p> <a href="https://publications.waset.org/abstracts/41708/hsa-mir-139-5p-acts-as-a-tumor-suppressor-by-targeting-c-met-in-non-small-cell-lung-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41708.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">343</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">131</span> Biological Significance of Long Intergenic Noncoding RNA LINC00273 in Lung Cancer Cell Metastasis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ipsita%20Biswas">Ipsita Biswas</a>, <a href="https://publications.waset.org/abstracts/search?q=Arnab%20Sarkar"> Arnab Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashikur%20Rahaman"> Ashikur Rahaman</a>, <a href="https://publications.waset.org/abstracts/search?q=Gopeswar%20Mukherjee"> Gopeswar Mukherjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Subhrangsu%20Chatterjee"> Subhrangsu Chatterjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Shamee%20Bhattacharjee"> Shamee Bhattacharjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Deba%20Prasad%20Mandal"> Deba Prasad Mandal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the major reasons for the high mortality rate of lung cancer is the substantial delays in disease detection at late metastatic stages. It is of utmost importance to understand the detailed molecular signaling and detect the molecular markers that can be used for the early diagnosis of cancer. Several studies explored the emerging roles of long noncoding RNAs (lncRNAs) in various cancers as well as lung cancer. A long non-coding RNA LINC00273 was recently discovered to promote cancer cell migration and invasion, and its positive correlation with the pathological stages of metastasis may prove it to be a potential target for inhibiting cancer cell metastasis. Comparing real-time expression of LINC00273 in various human clinical cancer tissue samples with normal tissue samples revealed significantly higher expression in cancer tissues. This long intergenic noncoding RNA was found to be highly expressed in human liver tumor-initiating cells, human gastric adenocarcinoma AGS cell line, as well as human non-small cell lung cancer A549 cell line. SiRNA and shRNA-induced knockdown of LINC00273 in both in vitro and in vivo nude mice significantly subsided AGS and A549 cancer cell migration and invasion. LINC00273 knockdown also reduced TGF-β induced SNAIL, SLUG, VIMENTIN, ZEB1 expression, and metastasis in A549 cells. Plenty of reports have suggested the role of microRNAs of the miR200 family in reversing epithelial to mesenchymal transition (EMT) by inhibiting ZEB transcription factors. In this study, hsa-miR-200a-3p was predicted via IntaRNA-Freiburg RNA tools to be a potential target of LINC00273 with a negative free binding energy of −8.793 kcal/mol, and this interaction was verified as a confirmed target of LINC00273 by RNA pulldown, real-time PCR and luciferase assay. Mechanistically, LINC00273 accelerated TGF-β induced EMT by sponging hsa-miR-200a-3p which in turn liberated ZEB1 and promoted prometastatic functions in A549 cells in vitro as verified by real-time PCR and western blotting. The similar expression patterns of these EMT regulatory pathway molecules, viz. LINC00273, hsa-miR-200a-3p, ZEB1 and TGF-β, were also detected in various clinical samples like breast cancer tissues, oral cancer tissues, lung cancer tissues, etc. Overall, this LINC00273 mediated EMT regulatory signaling can serve as a potential therapeutic target for the prevention of lung cancer metastasis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epithelial%20to%20mesenchymal%20transition" title="epithelial to mesenchymal transition">epithelial to mesenchymal transition</a>, <a href="https://publications.waset.org/abstracts/search?q=long%20noncoding%20RNA" title=" long noncoding RNA"> long noncoding RNA</a>, <a href="https://publications.waset.org/abstracts/search?q=microRNA" title=" microRNA"> microRNA</a>, <a href="https://publications.waset.org/abstracts/search?q=non-small-cell%20lung%20carcinoma" title=" non-small-cell lung carcinoma"> non-small-cell lung carcinoma</a> </p> <a href="https://publications.waset.org/abstracts/143383/biological-significance-of-long-intergenic-noncoding-rna-linc00273-in-lung-cancer-cell-metastasis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143383.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">130</span> LTF Expression Profiling Which is Essential for Cancer Cell Proliferation and Metastasis, Correlating with Clinical Features, as Well as Early Stages of Breast Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azar%20Heidarizadi">Azar Heidarizadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdieh%20Salimi"> Mahdieh Salimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Mozdarani"> Hossein Mozdarani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: As a complex disease, breast cancer results from several genetic and epigenetic changes. Lactoferrin, a member of the transferrin family, is reported to have a number of biological functions, including DNA synthesis, immune responses, iron transport, etc., any of which could play a role in tumor progression. The aim of this study was to investigate the bioinformatics data and experimental assay to find the pattern of promoter methylation and gene expression of LTF in breast cancer in order to study its potential role in cancer management. Material and Methods: In order to evaluate the methylation status of the LTF promoter, we studied the MS-PCR and Real-Time PCR on samples from patients with breast cancer and normal cases. 67 patient samples were conducted for this study, including tumoral, plasma, and normal tissue adjacent samples, as well as 30 plasma from normal cases and 10 tissue breast reduction cases. Subsequently, bioinformatics analyses such as cBioPortal databases, string, and genomatix were conducted to disclose the prognostic value of LTF in breast cancer progression. Results: The analysis of LTF expression showed an inverse relationship between the expression level of LTF and the stages of tissues of breast cancer patients (p<0.01). In fact, stages 1 and 2 had a high expression in LTF, while, in stages 3 and 4, a significant reduction was observable (p < 0.0001). LTF expression frequently alters with a decrease in the expression in ER⁺, PR⁺, and HER2⁺ patients (P < 0.01) and an increase in the expression in the TNBC, LN¯, ER¯, and PR- patients (P < 0.001). Also, LTF expression is significantly associated with metastasis and lymph node involvement factors (P < 0.0001). The sensitivity and specificity of LTF were detected, respectively. A negative correlation was detected between the results of level expression and methylation of the LTF promoter. Conclusions: The altered expression of LTF observed in breast cancer patients could be considered as a promotion in cell proliferation and metastasis even in the early stages of cancer. <p
