polymer, and it is derived from chitin. The objective of this research was to determine the growth promoting responses induced by chitosan at the molecular physiology level in Khao Dawk Mali 105 (KDML 105) rice (Oryza sativa L.) seedlings under drought stress by adding of 2% polyethylene glycol 4000 (PEG4000) to the nutrient solution and after removal of the drought stress (re-water). Oligomeric chitosan at 40 ppm could enhance shoot fresh weight and shoot dry weight during drought stress and re-water. After 7 days of drought stress and re-water, significant increases in chlorophyll a and chlorophyll b contents in KDML 105 cultivar were observed. The 749 phosphoproteins in rice leaf treated with chitosan could be resolved by phosphoprotein enrichment, tryptic digestion and liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis. They can be classified into 10 groups. Proteins involved in the metabolic process and biological regulation were upregulated in response to chitosan during drought stress. This work will help us to understand protein phosphorylation relating to chitosan response during drought stress in aromatic rice seedlings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chitosan" title="Chitosan">Chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=drought" title=" drought"> drought</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphoproteome" title=" phosphoproteome"> phosphoproteome</a>, <a href="https://publications.waset.org/abstracts/search?q=rice" title=" rice"> rice</a> </p> <a href="https://publications.waset.org/abstracts/109972/phosphoproteomic-analysis-of-the-response-of-rice-leaves-to-chitosan-under-drought-stress" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109972.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">164</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">3</span> Initiation of Paraptosis-Like PCD Pathway in Hepatocellular Carcinoma Cell Line by Hep88 mAb through the Binding of Mortalin (HSPA9) and Alpha-Enolase</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Panadda%20Rojpibulstit">Panadda Rojpibulstit</a>, <a href="https://publications.waset.org/abstracts/search?q=Suthathip%20Kittisenachai"> Suthathip Kittisenachai</a>, <a href="https://publications.waset.org/abstracts/search?q=Songchan%20Puthong"> Songchan Puthong</a>, <a href="https://publications.waset.org/abstracts/search?q=Sirikul%20Manochantr"> Sirikul Manochantr</a>, <a href="https://publications.waset.org/abstracts/search?q=Pornpen%20Gamnarai"> Pornpen Gamnarai</a>, <a href="https://publications.waset.org/abstracts/search?q=Sasichai%20Kangsadalampai"> Sasichai Kangsadalampai</a>, <a href="https://publications.waset.org/abstracts/search?q=Sittiruk%20Roytrakul"> Sittiruk Roytrakul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hepatocellular carcinoma (HCC) is the most primary hepatic cancer worldwide. Nowadays a targeted therapy via monoclonal antibodies (mAbs) specific to tumor-associated antigen is continually developed in HCC treatment. In this regard, after establishing and consequently exploring Hep88 mAb’s tumoricidal effect on hepatocellular carcinoma cell line (HepG2 cell line), the Hep88 mAb’s specific Ag from both membrane and cytoplasmic fractions of HepG2 cell line was identified by 2-D gel electrophoresis and western blot analysis. After in-gel digestion and subsequent analysis by liquid chromatography-mass spectrometry (LC-MS), mortalin (HSPA9) and alpha-enolase were identified. The recombinant proteins specific to Hep88 mAb were cloned and expressed in E.coli BL21 (DE3). Moreover, alteration of HepG2 and Chang liver cell line after being induced by Hep88 mAb for 1-3 days was investigated using a transmission electron microscope. The result demonstrated that Hep88 mAb can bind to the recombinant mortalin (HSPA9) andalpha-enolase. In addition, gradual appearance of mitochondria vacuolization and endoplasmic reticulum dilatation were observed. Taken together, paraptosis-like programmed cell death (PCD) of HepG2 is induced by binding of mortalin (HSPA9) and alpha-enolase to Hep88 mAb. Mortalin depletion by formation of Hep88 mAb-mortalin (HSPA9) complex might initiate transcription-independent of p53-mediated apoptosis. Additionally, Hep88 mAb-alpha-enolase complex might initiate HepG2 cells energy exhaustion by glycolysis pathway obstruction. These results imply that Hep88 mAb might be a promising tool for development of an effective treatment of HCC in the next decade. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hepatocellular%20carcinoma" title="Hepatocellular carcinoma">Hepatocellular carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=Monoclonal%20antibody" title=" Monoclonal antibody"> Monoclonal antibody</a>, <a href="https://publications.waset.org/abstracts/search?q=Paraptosis-like%20program%20cell%20death" title=" Paraptosis-like program cell death"> Paraptosis-like program cell death</a>, <a href="https://publications.waset.org/abstracts/search?q=Transmission%20electron%20microscopy" title=" Transmission electron microscopy"> Transmission electron microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=mortalin%20%28HSPA9%29" title=" mortalin (HSPA9)"> mortalin (HSPA9)</a>, <a href="https://publications.waset.org/abstracts/search?q=alpha-enolase" title="alpha-enolase">alpha-enolase</a> </p> <a href="https://publications.waset.org/abstracts/4778/initiation-of-paraptosis-like-pcd-pathway-in-hepatocellular-carcinoma-cell-line-by-hep88-mab-through-the-binding-of-mortalin-hspa9-and-alpha-enolase" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4778.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">361</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">2</span> Differential Proteomics Expression in Purple Rice Supplemented Type 2 Diabetic Rats’ Skeletal Muscle </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ei%20Ei%20Hlaing">Ei Ei Hlaing</a>, <a href="https://publications.waset.org/abstracts/search?q=Narissara%20Lailerd"> Narissara Lailerd</a>, <a href="https://publications.waset.org/abstracts/search?q=Sittiruk%20Roytrakul"> Sittiruk Roytrakul</a>, <a href="https://publications.waset.org/abstracts/search?q=Pichapat%20Piamrojanaphat"> Pichapat Piamrojanaphat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Type 2 diabetes is one of the most common metabolic diseases all over the world. The pathogenesis of type 2 diabetes is not the only dysfunction of pancreatic beta cells but also insulin resistance in muscle, liver and adipose tissue. High levels of circulating free fatty acids, an increased lipid content of muscle cells, impaired insulin-mediated glucose uptake and diminished mitochondrial functioning are pathophysiological hallmarks of diabetic skeletal muscles. Purple rice (Oryza sativa L. indica) has been shown to have antidiabetic effects. However, the underlying mechanism(s) of antidiabetic activity of purple rice is still unraveled. In this research, to explore in-depth cellular mechanism(s), proteomic profile of purple rice supplemented type 2 diabetic rats’ skeletal muscle were analyzed contract with non-supplemented rats. Diabetic rats were induced high-fat diet combined with streptozotocin injection. By using one- dimensional gel electrophoresis (1-DE) and LC-MS/MS quantitative proteomic method, we analyzed proteomic profiles in skeletal muscle of normal rats, normal rats with purple rice supplementation, type 2 diabetic rats, and type 2 diabetic rats with purple rice supplementation. Total 2676 polypeptide expressions were identified. Among them, 24 peptides were only expressed in type 2 diabetic rats, and 24 peptides were unique peptides in type 2 diabetic rats with purple rice supplementation. Acetyl CoA carboxylase 1 (ACACA) found as unique protein in type 2 diabetic rats which is the major enzyme in lipid synthesis and metabolism. Interestingly, DNA damage response protein, heterogeneous nuclear ribonucleoprotein K [Mus musculus] (Hnrnpk), was upregulated in type 2 diabetic rats’ skeletal muscle. Meanwhile, unique proteins of type 2 diabetic rats with purple rice supplementation (bone morphogenetic 7 protein preproprotein, BMP7; and forkhead box protein NX4, Foxn4) involved with muscle cells growth through the regulation of TGF-β/Smad signaling network. Moreover, BMP7 may effect on insulin signaling through the downstream signaling of protein kinase B (Akt) which acts in protein synthesis, glucose uptake, and glycogen synthesis. In conclusion, our study supports that type 2 diabetes impairs muscular lipid metabolism. In addition, purple rice might recover the muscle cells growth and insulin signaling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=proteomics" title="proteomics">proteomics</a>, <a href="https://publications.waset.org/abstracts/search?q=purple%20rice%20bran" title=" purple rice bran"> purple rice bran</a>, <a href="https://publications.waset.org/abstracts/search?q=skeletal%20muscle" title=" skeletal muscle"> skeletal muscle</a>, <a href="https://publications.waset.org/abstracts/search?q=type%202%20diabetic%20rats" title=" type 2 diabetic rats"> type 2 diabetic rats</a> </p> <a href="https://publications.waset.org/abstracts/58923/differential-proteomics-expression-in-purple-rice-supplemented-type-2-diabetic-rats-skeletal-muscle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58923.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">253</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">1</span> The Expression Patterns of Thai Moderately Salt Tolerant Rice and High Salt Tolerant Rice in Response to Salt Stress</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kongngern%20K.">Kongngern K.</a>, <a href="https://publications.waset.org/abstracts/search?q=Homwonk%20C."> Homwonk C.</a>, <a href="https://publications.waset.org/abstracts/search?q=Theerakulpisut%20P."> Theerakulpisut P.</a>, <a href="https://publications.waset.org/abstracts/search?q=Roytrakul%20R."> Roytrakul R.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rice cultivation is crucial globally, especially in Asia. Soil salinity poses a significant challenge for agricultural lands. Understanding the expression patterns of different rice varieties under salt stress can provide insights for developing more salt-tolerant cultivars. This study aims to compare the expression patterns of two rice varieties, Thai moderately salt-tolerant rice (Leaung Anan) and high salt-tolerant rice (Pokkali), in response to salt stress. By analyzing protein expression, the research seeks to identify key proteins associated with salt tolerance in rice. The expression patterns of the two rice varieties under salt stress were analyzed using 1D-SDS-PAGE, NanoLC-MS/MS, and MEV software. These methods enabled the researchers to assess the differential expression of proteins in the leaf sheaths of the rice plants. These results indicate that the study identified 18 proteins, exhibited significantly different expression patterns between the two rice cultivars under salt stress. Notably, certain proteins, such as Os05g0364500 and pr1-like protein, showed contrasting expression profiles in the two varieties. The up-regulated proteins, predominantly observed in the salt-tolerant rice, may contribute to the survival of rice plants under salt stress and may provide valuable insights for breeding programs aiming to enhance salt tolerancein rice cultivars. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mass%20spectrometry" title="mass spectrometry">mass spectrometry</a>, <a href="https://publications.waset.org/abstracts/search?q=proteomics" title=" proteomics"> proteomics</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20leaf%20sheaths" title=" rice leaf sheaths"> rice leaf sheaths</a>, <a href="https://publications.waset.org/abstracts/search?q=salt%20stress" title=" salt stress"> salt stress</a> </p> <a href="https://publications.waset.org/abstracts/194601/the-expression-patterns-of-thai-moderately-salt-tolerant-rice-and-high-salt-tolerant-rice-in-response-to-salt-stress" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194601.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">8</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
