Functionally, WTAP hindered the proliferation, growth, migration and invasion of melanoma cells. Furthermore, NT5E was identified as the downstream effector of WTAP and was subsequently found to rescue the increased proliferation, migration and invasion of melanoma cells induced by WTAP deficiency. Moreover, knockdown of WTAP increased the expression of NT5E, MMP2 and N-cadherin, and simultaneous transfection with siNT5E reversed the increased expression of MMP2 and N-cadherin.

It serves as a central regulator of vital biological processes like cell proliferation, survival, and autophagy. Numerous studies have linked mTOR pathway activation to tumor progression. DEPTOR, a common negative regulator of mTORC1 and mTORC2, exhibits complex loop regulatory mechanisms beyond simple mTOR pathway modulation. Depending on the cell type or tissue environment, DEPTOR can act as either an oncogene or a tumor suppressor gene. Given its complex role in tumorigenesis, precise regulation of DEPTOR expression across different tumor types is imperative. DEPTOR has emerged as a key focus in research on human malignant tumors. While recent years have seen through investigations into DEPTOR expression regulation in tumors, a systematic literature review is lacking. This review provides a detailed summary of the mechanisms regulating DEPTOR expression, an mTOR inhibitor in tumors, covering DNA induction, transcription, translation, and post-translational modification. Additionally, it explores the potential applications of DEPTOR/mTOR signaling axis-related compounds in tumor therapy.</p>","PeriodicalId":19266,"journal":{"name":"Neoplasma","volume":" ","pages":"1-15"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143753721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
