摘要 聚ADP核糖聚合酶-1(PARP-1)能修复DNA损伤,从而维持细胞内环境与基因组稳定。多数恶性肿瘤细胞中PARP-1活性增强,因此,敲除PARP-1基因或使用PARP-1抑制剂能降低肿瘤细胞的DNA修复功能,增强其对DNA损伤因子的敏感性,从而提高肿瘤放疗和化疗疗效。PARP-1有望成为恶性肿瘤治疗的一个新靶点。 Poly(ADP-ribose) polymerase 1 (PARP-1 ) plays an essential role in DNA repair and maintenance of homeostasis and genome stability. Increased PARP-1 activity has been reported in various forms of cancer. Thus the absence of PARP- 1 or the use of its inhibitors depresses DNA repair function, sensitizes cancer cells to DNA damage and enhances the therapeutic effect of radio-or chemotherapy. PARP- 1 is potentially a therapeutic target of malignant tumors.
