Oxidative stress is related to the pathogenesis of several chronic diseases, including inflammatory processes. Free radicals excess increase not only oxidative stress but also genomic instability. Polyphenols are non-enzymatic antioxidants that act as a defense barrier against free radicals and non-radical oxidants. The purpose of this article was to review published articles relating dietary polyphenols contained in grape seed proanthocyanidin extracts with its potential for reversing DNA damage.
Proanthocyanidin components exert pleiotropic actions having several biological, biochemical, and significant pharmacological effects and showed the ability to reduce cytotoxicity and genotoxicity. Grape seed proanthocyanidin extracts showed the ability to reduce cytotoxicity and genotoxicity through the comet assay and the micronucleus technique.
氧化应激与包括炎症过程在内的多种慢性疾病的发病机制有关。自由基过量不仅会增加氧化应激,还会导致基因组不稳定。多酚是一种非酶抗氧化剂,可作为抵御自由基和非自由基氧化剂的防御屏障。本文旨在综述已发表的关于葡萄籽原花青素提取物中所含膳食多酚及其逆转DNA损伤潜力的文章。
原花青素成分具有多效性作用,具有多种生物学、生化和显著的药理作用,并显示出降低细胞毒性和遗传毒性的能力。葡萄籽原花青素提取物通过彗星试验和微核技术显示出降低细胞毒性和遗传毒性的能力。
