Abstract:
Sirtuin 2 (SIRT2) belongs to the sirtuins family. It exists in many tissues and organs of the human body and regulates a wide range of biological functions. Studies have found that the abnormal expression of SIRT2 was associated with a variety of malignant tumors. SIRT2 possesses an important role in tumorigenesis, with both tumor-promoting and tumor-suppressing function. However, the mechanisms in which SIRT2 plays the roles in cancer are still controversial. This article reviews the role and molecular mechanism of SIRT2 in tumor evolution, and provides ideas for future research in this field, to guide the targeted therapy and drug development of related malignancies.
Insights
Sirtuin 2 (SIRT2) impacts cancer development, acting as both a tumor promoter and suppressor. Understanding its complex role is key for developing targeted cancer therapies.
Area of Science:
- Biochemistry
- Molecular Biology
- Oncology
Background:
- Sirtuin 2 (SIRT2) is a protein deacetylase found in human tissues, regulating diverse biological functions.
- Abnormal SIRT2 expression is linked to various malignant tumors, indicating its involvement in cancer.
- SIRT2's precise role in tumorigenesis, whether promoting or suppressing, remains debated.
Purpose of the Study:
- To review the multifaceted role of SIRT2 in tumor evolution.
- To elucidate the molecular mechanisms underlying SIRT2's functions in cancer.
- To offer insights for future research and guide targeted therapy development.
Main Methods:
- Literature review of existing studies on SIRT2 and cancer.
- Analysis of molecular pathways involving SIRT2 in tumorigenesis.
- Synthesis of current knowledge on SIRT2's dual role in cancer.
Main Results:
- SIRT2 exhibits context-dependent functions in cancer, acting as both an oncogene and a tumor suppressor.
- Evidence suggests SIRT2 influences key cellular processes like cell cycle, DNA repair, and metabolism in tumors.
- The molecular mechanisms are complex and vary across different cancer types.
Conclusions:
- SIRT2 is a critical player in cancer progression with a dual role.
- Further research into SIRT2's mechanisms is essential for clinical applications.
- Targeting SIRT2 may offer novel therapeutic strategies for malignancies.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
