The Role of Sirtuin 2 in Chemotherapeutic Resistance

The lack of effective chemotherapy agents and the development of multi-drug resistance in advanced cancers are major encountered issues during treatment phase. The resistance of cancer cells against chemotherapeutic agents may occur as a result of different mechanisms. The identification of molecular pathways involved in drug resistance will yield the occurrence of alternative therapeutic strategies. Sirtuin 2 is one of the NAD-dependent deacetylases. It is involved in carcinogenesis to fulfill oncogenic and tumor-suppressing functions. Therefore, Sirtuin 2 modulation becomes a promising approach in cancer treatments. A better understanding of Sirtuin 2 related pathways is required to provide guidance to alternative cancer treatments. There are several studies about the effects of Sirtuin 2 on various types of cancers in recent years. Within the scope of this review, it is aimed to present the molecular pathways of Sirtuin 2 and its association with chemotherapeutic resistance.
