本文综述了聚腺苷二磷酸核糖参与哺乳动物细胞辐射反应的证据。结论是,使用ADP-核糖基转移酶(ADPRT)抑制剂的明显相互矛盾的结果可以用工作假说来解释。这一假说认为,多聚(ADP-核糖)是修复辐射损伤所必需的(可能是为了促进连接)。在大多数细胞中,聚(ADP-核糖)的合成不是修复的速率限制,因此,需要几乎完全抑制ADPRT活性来增强辐射反应。在辐射敏感细胞(如静息淋巴细胞、L5178Y-S细胞)中,聚腺苷二磷酸核糖代谢缺陷,其合成可能成为修复的限速。在这类细胞中,即使部分抑制ADPRT活性也可能增强辐射诱导的细胞杀伤。提示如果正常细胞和癌细胞之间存在这种差异,则可以利用它们来提高放射治疗的比率。
The evidence implicating poly (ADP-ribose) in the radiation response of mammalian cells is reviewed. It is concluded that the apparently conflicting results using inhibitors of ADP-ribosyl transferase (ADPRT) can be explained by a working hypothesis. This hypothesis maintains that poly (ADP-ribose) is required for repair of radiation damage (presumably to facilitate ligation). In most cells the synthesis of poly (ADP-ribose) is not rate limiting for repair and therefore, an almost complete inhibition of ADPRT activity is required to potentiate the radiation response. In radiation-sensitive cells (e.g. resting lymphocytes, L5178Y-S cells) with a deficient poly (ADP-ribose) metabolism, its synthesis can become rate limiting for repair. In such cells even a partial inhibition of ADPRT activity may enhance radiation-induced cell killing. It is suggested that if such differences exist between normal and cancer cells, they can be utilized to improve the therapeutic ratio of radiotherapy.
