Research progress on the regulation mechanism of DEPTOR expression and its role in tumorigenesis

Area of Science:

• Oncology
• Molecular Biology
• Biochemistry

Background:

• The mammalian target of rapamycin (mTOR) pathway regulates cell growth, proliferation, and survival.
• mTOR pathway dysregulation is implicated in various human cancers.
• DEPTOR is a key negative regulator of mTORC1 and mTORC2, with a complex role in tumorigenesis.

Purpose of the Study:

• To systematically review the regulatory mechanisms of DEPTOR expression in tumors.
• To explore the dual role of DEPTOR as an oncogene or tumor suppressor.
• To discuss the therapeutic potential of targeting the DEPTOR/mTOR signaling axis.

Main Methods:

• Systematic literature review of studies on DEPTOR expression regulation in tumors.
• Analysis of DEPTOR regulation at the levels of DNA induction, transcription, translation, and post-translational modification.
• Review of preclinical and clinical studies on DEPTOR/mTOR signaling in cancer therapy.

Main Results:

• DEPTOR expression is tightly regulated through multiple mechanisms, including transcriptional, translational, and post-translational modifications.
• DEPTOR's function as an oncogene or tumor suppressor is context-dependent, varying with cell type and tumor environment.
• The DEPTOR/mTOR signaling axis presents a promising target for novel cancer therapeutics.

Conclusions:

• Understanding DEPTOR's complex regulatory network is crucial for its role in cancer.
• Targeting DEPTOR and the mTOR pathway offers potential for innovative cancer treatment strategies.
• Further research into DEPTOR's precise role in different tumor types is warranted for personalized therapy.
