Our work aimed to investigate the protective effects of saponin-based nanoemulsions of vitamin A and E against oxidative stress-induced cellular damage in AML-12 cells. Saponin nanoemulsions of vitamin A (SAN) and vitamin E (SEN) were prepared by high-pressure homogenization and characterized in terms of size, zeta potential, and polydispersity index. SEN and SAN protect AML-12 cells against oxidative stress-induced cellular damage more efficiently via scavenging reactive oxygen species (ROS), and reducing DNA damage, protein carbonylation, and lipid peroxidation. These results provide valuable information for the development of nanoemulsion-based delivery systems that would improve the antioxidant properties of vitamin A and E.
我们的工作旨在研究基于皂苷的维生素A和E纳米乳剂对急性髓系白血病12(AML-12)细胞中氧化应激诱导的细胞损伤的保护作用。通过高压均质法制备了维生素A皂苷纳米乳剂(SAN)和维生素E皂苷纳米乳剂(SEN),并对其粒径、ζ电位和多分散指数进行了表征。SEN和SAN通过清除活性氧(ROS),减少DNA损伤、蛋白质羰基化和脂质过氧化,更有效地保护AML-12细胞免受氧化应激诱导的细胞损伤。这些结果为开发基于纳米乳剂的递送系统提供了有价值的信息,该系统将改善维生素A和E的抗氧化性能。
