Risk-score analysis combined with clinic pathological characteristics to assess the prognostic value and immunotherapy efficacy of 6-genes signature. Methods: We performed the whole exosome sequencing profiling on samples form patients with GBM. The association of PIK3CA and NF1 expression within the GBM have received cross-validations by Mendelian Randomization (MR) methods and the risk-score analysis of 6-gene signature. Results: MR study demonstrated that PIK3CA and NF1 expressions were closely related with the risk of GBM patients by the Inverse Variance Weighting (IVW) method and then the construction of 6-gene signature was classified into high-risk and low-risk groups through the median risk-score of regression formula to predict prognosis of GBM patients. Kaplan-Meier survival showed the overall survival of distinct high and low-risk groups. Receiver Operating Characteristic (ROC) curve analysis indicated the value of predictive performance of two different risk groups. In line with our Whole Exome Sequencing reporters (WES), our findings showed that the mutation of PIK3CA and NF1 was significantly associated with prognostic signature of GBM. Conclusion: Taken together, our MR analysis indicated the correlation between PIK3CA and NF1 expression and GBM disease, which provided a key basis for the precise prevention of the genetic mutation in the occurrence and development of GBM. The established PIK3CA and NF1 alteration-related prognostic signature was involved well in prognosis prediction as well as closely linked with immunotherapy responses."> <meta

Receiver Operating Characteristic (ROC) curve analysis indicated the value of predictive performance of two different risk groups. In line with our Whole Exome Sequencing reporters (WES), our findings showed that the mutation of PIK3CA and NF1 was significantly associated with prognostic signature of GBM.</p> <p><strong>Conclusion:</strong> Taken together, our MR analysis indicated the correlation between PIK3CA and NF1 expression and GBM disease, which provided a key basis for the precise prevention of the genetic mutation in the occurrence and development of GBM. The established PIK3CA and NF1 alteration-related prognostic signature was involved well in prognosis prediction as well as closely linked with immunotherapy responses. <div class="alert alert-info text-left"><b>నిరాకరణ:</b> ఈ సారాంశం కృత్రిమ మేధస్సు సాధనాలను ఉపయోగించి అనువదించబడింది మరియు ఇంకా సమీక్షించబడలేదు లేదా ధృవీకరించబడలేదు.</div> <div class="nav social-icons"> <a class="nav-link w-auto">ఈ కథనాన్ని భాగస్వామ్యం చేయండి</a> <a title="ఇక్కడ నొక్కండి" target="_blank" href="https://www.facebook.com/sharer.php?u=https://telugu.longdom.org/abstract/analysis-of-integrating-empik3caem-and-emnf1em-mutations-into-glioblastoma-multiforme-prognostication-and-immunotherapy--108801.html" rel="noopener"><i class="fab fa-facebook-f"></i></a> <a class="nav-link" title="ఇక్కడ నొక్కండి" target="_blank" href="https://twitter.com/share?url=https://telugu.longdom.org/abstract/analysis-of-integrating-empik3caem-and-emnf1em-mutations-into-glioblastoma-multiforme-prognostication-and-immunotherapy--108801.html" rel="noopener"><i class="fab fa-twitter"></i></a> <a class="nav-link" title="ఇక్కడ నొక్కండి" target="_blank" href="https://www.linkedin.com/shareArticle?mini=true&url=https://telugu.longdom.org/abstract/analysis-of-integrating-empik3caem-and-emnf1em-mutations-into-glioblastoma-multiforme-prognostication-and-immunotherapy--108801.html" rel="noopener"><i class="fab fa-linkedin-in"></i></a> <a class="nav-link" title="ఇక్కడ నొక్కండి" target="_blank" href="https://plus.google.com/share?url=https://telugu.longdom.org/abstract/analysis-of-integrating-empik3caem-and-emnf1em-mutations-into-glioblastoma-multiforme-prognostication-and-immunotherapy--108801.html" rel="noopener"><i class="fab fa-google-plus-g"></i></a> </div> </div> </div> </div> </section> <footer class="bg-blue-grey-900 py-3"> <div class="container"> <div class="row"> <div class="col-12 col-sm-4"> <h4 class="white font-size-4 fweight-400 border-bottom-1 pb-2">కంటెంట్ లింక్‌లు</h4> <ul class="list-unstyled footer-links font-size-3"> <li><a class="" href="https://telugu.longdom.org/privacy-policy.html" title="ఇక్కడ నొక్కండి">గోప్యతా విధానం</a></li> <li><a class="" href="https://telugu.longdom.org/terms-conditions.html" title="ఇక్కడ నొక్కండి">నిబంధనలు & షరతులు</a></li> <li><a class="" href="https://telugu.longdom.org/authors-reviewers-editors.html" title="ఇక్కడ నొక్కండి">రచయితలు, సమీక్షకులు & ఎడిటో</a></li> </ul> </div> <div class="col-12 col-sm-4"> <h4 class="white font-size-4 fweight-400 border-bottom-1 pb-2">లాంగ్‌డమ్‌ను సంప్రదించండి</h4> <p><strong>లాంగ్‌డమ్ గ్రూప్ SA</strong><br /> అవెన్యూ రోజర్ వాండెండ్రీస్చే,<br /> 18, 1150 బ్రస్సెల్స్, బెల్జియం<br /> ఫోన్: +442038085340<br /> <strong>ఇమెయిల్:</strong> <a class="white" href="mailto:info@longdom.org" title="Click here">info@longdom.org</a></p> </div> <div class="col-12 col-sm-4"> <h4 class="white font-size-4 fweight-400 border-bottom-1 pb-2">కనెక్ట్ చేయండి</h4> <nav class="nav nav-pills social-icons-footer flex-column a-pl-0"> <a href="https://www.facebook.com/longdompublisher" title="ఇక్కడ నొక్కండి" target="_blank" class="nav-link bg-facebook-hover"><i class="fab fa-facebook-f bg-facebook"></i></a> <a href="https://www.linkedin.com/company/longdom-publishing-sl/" title="ఇక్కడ నొక్కండి" target="_blank" class="nav-link bg-linkedin-hover"><i class="fab fa-linkedin-in bg-linkedin"></i></a> <a href="https://twitter.com/LongdomP" title="ఇక్కడ నొక్కండి" target="_blank" class="nav-link bg-twitter-hover"><i class="fab fa-twitter bg-twitter"></i></a> <a href="https://www.instagram.com/longdom_publisher/" title="ఇక్కడ నొక్కండి" target="_blank" class="nav-link bg-instagram-hover"><i class="fab fa-instagram bg-instagram"></i></a> </nav> </div> </div> <div class="row text-center"> <div class="col"> <p>కాపీరైట్ © 2024 <a href="https://telugu.longdom.org/" title="ఇక్కడ నొక్కండి" class="white">లాంగ్‌డమ్ పబ్లిషింగ్ SL</a>.</p> </div> </div> </div> </footer>  <a href="#0" class="cd-top js-cd-top">Top</a>   <script src="https://code.jquery.com/jquery-3.3.1.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>  <script> jQuery(function($) { $(window).scroll(function fix_element() { $('#target').css( $(window).scrollTop() > 100 ?
