现有文献表明腺瘤性结肠息肉病(APC)基因具有多种细胞功能。其中,最近发现APC的独特作用是在DNA修复中。APC基因可通过与DNA聚合酶β(Pol-β)和瓣状核酸内切酶1(Fen-1)的相互作用来调节碱基切除修复(BER)途径。APC与烷化剂对APC基因的转录激活和BER活性的调节一起,可能通过决定DNA损伤细胞的存活或凋亡而在肿瘤发生和化疗中发挥重要作用。在这篇综述中,我们总结了支持这一新概念的证据,并建议这些结果将对某些类型肿瘤的化学预防,预后和化疗的更有效的策略的发展产生影响。
Prevailing literature suggests diversified cellular functions for the adenomatous polyposis coli (APC) gene. Among them a recently discovered unique role of APC is in DNA repair. The APC gene can modulate the base excision repair (BER) pathway through an interaction with DNA polymerase β (Pol-β) and flap endonuclease 1 (Fen-1). Taken together with the transcriptional activation of APC gene by alkylating agents and modulation of BER activity, APC may play an important role in carcinogenesis and chemotherapy by determining whether cells with DNA damage survive or undergo apoptosis. In this review, we summarize the evidence supporting this novel concept and suggest that these results will have implications for the development of more effective strategies for chemoprevention, prognosis, and chemotherapy of certain types of tumors.
