该综述对MGMT的潜在作用和结构特性、靶向MGMT的研究进展以及MGMT与DNA损伤处理中的DNA修复途径之间的相互作用进行了全面的研究。O6-甲基鸟嘌呤-DNA甲基转移酶(MGMT或AGT)是一种DNA修复蛋白,具有从O6-烷基G加合物中去除烷基的能力。此外,MGMT在甲基化药物替莫唑胺和氯乙基化药物如卡莫司汀引起的DNA损伤修复中起着至关重要的作用,从而在使用这些药物时导致化疗耐药。本文对MGMT的结构作用和修复机制进行了综述,重点介绍了MGMT N-末端结构域的潜在结构和功能作用。它还探索了针对MGMT的癌症治疗策略的发展。最后,它讨论了MGMT和其他DNA修复途径之间有趣的串扰。
This review offers a thorough examination of the potential role and structural properties of MGMT, the progression in targeting MGMT, and the interactions between MGMT and DNA repair pathways involved in processing DNA lesions. O6-methylguanine-DNA methyltransferase (MGMT or AGT) is a DNA repair protein with the capability to remove alkyl groups from O6-AlkylG adducts. Moreover, MGMT plays a crucial role in repairing DNA damage induced by methylating agents like temozolomide and chloroethylating agents such as carmustine, and thereby contributes to chemotherapeutic resistance when these agents are used. This review delves into the structural roles and repair mechanisms of MGMT, with emphasis on the potential structural and functional roles of the N-terminal domain of MGMT. It also explores the development of cancer therapeutic strategies that target MGMT. Finally, it discusses the intriguing crosstalk between MGMT and other DNA repair pathways.
