The aim was to evaluate the roles of PTP4As in cancer development and progression, as previous research has primarily focused on PTP4A3 and yielded inconsistent results regarding their expression in cancers.</p></div><div><h3>Methods</h3><p>A meticulous and extensive analysis of PTP4As was performed across diverse cancer types. mRNA expression levels of PTP4A isoforms were examined, and correlations between protein expression and mRNA expression were investigated. Genomic alterations affecting PTP4As, such as amplification, were analyzed. Survival analysis was conducted to assess the prognostic values of PTP4As in different cancers.

The correlation between PTP4As protein expression and mRNA expression was found to be weak, indicating the complexity of their regulatory mechanisms. Genomic analysis showed that amplification was the major type of alteration affecting PTP4As, although it did not always translate into higher expression.

Pathway enrichment analysis unveiled novel signaling pathways and biological processes potentially influenced by PTP4As.</p></div><div><h3>Conclusion</h3><p>The pan-cancer analysis of PTP4As provided insights into their aberrant expression, genomic alterations, prognostic values, and molecular functions. PTP4A3 exhibited the most prevalent up-regulation, while PTP4A2 showed a general up-regulated trend. Inconsistent results were observed for PTP4A1 expression, warranting further investigation. These findings contribute to our understanding of the molecular mechanisms through which PTP4As may contribute to cancer pathogenesis.</p></div>","PeriodicalId":100787,"journal":{"name":"Journal of Holistic Integrative Pharmacy","volume":"4 2","pages":"Pages 185-198"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2707368823000833/pdfft?md5=b0cfe552a83493e964260d2b5cd49d85&pid=1-s2.0-S2707368823000833-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82838206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
