摘要: DNA双链断裂作为最严重的DNA损伤是引起人体基因组不稳定和引起基因疾病形成的潜在因素。研究发现,多种食物成分具有抑制DNA双链断裂、促进DNA损伤修复的功能。本文主要概括了近20 年来国内外报道的对DNA双链断裂损伤具有调节功能的食物成分,从抗氧化作用、调节DNA损伤修复和抗氧化同时调节DNA损伤修复3 个方面阐述了食物成分缓解肠道细胞DNA双链断裂损伤的作用机制,并探讨了不同摄入时间和摄入剂量对DNA双链断裂损伤保护效果的影响,对可能缓解DNA双链断裂损伤的其他潜在食物成分进行展望,为开发新型缓解DNA双链断裂损伤的食物提供理论参考。

Abstract: As the most dangerous type of DNA damage, DNA double strand breaks (DSBs) are a potential factor causing human genome instability and promoting the occurrence of genetic diseases. In many studies, it has been found that many food ingredients can inhibit the formation of DSBs or promote DNA damage repair. This paper mainly summarizes the food ingredients reported in the recent 20 years that have a regulatory function on DSBs. The mechanism of food ingredients in alleviating DSBs in human intestinal cells is expounded from three aspects: antioxidant effect, regulation of DNA damage repair and simultaneous action of both functions. The influence of different intakes and ingestion times of food components on the protective effect on DSBs is discussed as well. The possible protective effect of other potential food components on DSBs is proposed, aiming to provide a theoretical reference for the development of new types of foods that can alleviate DSBs.
