- Abstract
As the aging phenomenon continues to increase, the incidence of neurodegenerative diseases continues to increase annually. As one of the significant contributive factors of neurodegenerative diseases, oxidative stress damage has received extensive attention in recent years. Oxidative stress plays an important role in neuronal damage through various apoptotic mechanisms related to neurodegenerative diseases. The use of natural antioxidants to combat oxidative stress may be a useful approach in delaying disease progression. In this study, we explored the neuroprotective effect of hyperoside on rat pheochromoma (PC12) cells. Specifically, the antioxidant effect and mechanism of hyperoside in hydrogen peroxide (H2O2)-induced cellular cytotoxicity were investigated. Our results showed that hyperoside could significantly increase the survival rate of rat PC12 cells when exposed to H2O2. In addition, hyperoside regulated the expression of genes and proteins in the corresponding pathways by up-regulating the phosphatidylinositol-3-kinase (PI3K), protein kinase B (Akt), and light chain 3ß (LC3B) pathways and down-regulating the nuclear factor-κ-gene binding (NF-κB), Bcl2-associated X (Bax), cysteinyl aspartate specific proteinase 3 (Caspase 3), and P62 pathways, thereby inhibiting cell apoptosis. Therefore, hyperoside can effectively inhibit H2O2-induced oxidative stress damage by regulating inflammation, autophagy, and apoptosis-related pathways.
