槲皮素是中草药、水果和葡萄酒中的一种植物来源的黄酮类化合物,在许多与氧化应激相关的病理过程中表现出抗氧化特性。然而,槲皮素对氧化应激下植入前胚胎发育的影响尚不清楚。本研究旨在确定槲皮素对过氧化氢 (H2O2) 诱导的小鼠受精卵氧化损伤的保护作用和潜在作用机制。 H2O2 处理会损害小鼠受精卵的体外发育,降低囊胚形成和孵化率,并增加囊胚的破碎、凋亡和迟缓。槲皮素通过降低活性氧水平、维持线粒体功能和调节总抗氧化能力、酶促抗氧化剂的活性(包括谷胱甘肽过氧化物酶和过氧化氢酶活性)来强烈保护受精卵免受H2O2诱导的氧化损伤,以保持细胞氧化还原环境。此外,槲皮素对谷胱甘肽(胚胎中主要的非酶抗氧化剂)的水平没有影响。
Quercetin, a plant-derived flavonoid in Chinese herbs, fruits and wine, displays antioxidant properties in many pathological processes associated with oxidative stress. However, the effect of quercetin on the development of preimplantation embryos under oxidative stress is unclear. The present study sought to determine the protective effect and underlying mechanism of action of quercetin against hydrogen peroxide (H2O2)-induced oxidative injury in mouse zygotes. H2O2 treatment impaired the development of mouse zygotes in vitro, decreasing the rates of blastocyst formation and hatched, and increasing the fragmentation, apoptosis and retardation in blastocysts. Quercetin strongly protected zygotes from H2O2-induced oxidative injury by decreasing the reactive oxygen species level, maintaining mitochondrial function and modulating total antioxidant capability, the activity of the enzymatic antioxidants, including glutathione peroxidase and catalase activity to keep the cellular redox environment. Additionally, quercetin had no effect on the level of glutathione, the main non-enzymatic antioxidant in embryos.
