6 氧 甲基鸟嘌呤 DNA甲基转移酶 (O6 methylguanine DNAmethyltransferase ,MGMT)是一种高效的DNA直接修复酶 ,能修复DNA序列中的 6 氧 甲基鸟嘌呤 (O6 methylgu nine ,O6 mG)损伤 ,是人类细胞中迄今发现的唯一一种修复该损伤的甲基转移酶。近年来MGMT基因的多态性对肿瘤的?
6 OG methylguanine DNA methyltransferase (MGMT) is a highly efficient DNA direct repair enzyme that can repair the damage of O6 methylguanine (O6 mG) It is the only methyltransferase in human cells that has been found so far to repair this damage. In recent years, MGMT gene polymorphism of the tumor?
