换一批摘要碱基切除修复(BER)是DNA氧化损伤修复的重要通路,该通路的突变造成基因不稳定而增加癌症风险.大量研究已证明,BER通路的关键蛋白,如DNA糖基化酶、脱嘌呤/嘧啶核酸内切酶1、DNA聚合酶等,在多种肿瘤中异常表达.此外这些蛋白的单核苷酸多态性影响肿瘤细胞的修复活性,有望成为肿瘤诊断、治疗及预后评估的重要指标.

abstractsBase excision repair (BER) is an important pathway for DNA oxidative damage repair,and mutations in this pathway cause gene instability and increase cancer risk.A large number of studies have shown that abnormal expression of key proteins in the BER pathway in a variety of tumors,such as DNA glycosylase,apurinic/apyrimidinic endonuclease 1,DNA polymerase and so on.Single nucleotide polymorphisms of these proteins affect the repair activity of tumor cells,and are expected to be important indicators for the diagnosis,treatment and evaluation of prognosis.
