Objective: To investigate the neuroprotective effects and mechanism of hyperin on CoCl2-induced hypoxic/ischemic PC12 cells.
Method: CoCl2 was used to treat rat pheochromocytoma cell line (PC12) to investigate the protective effects of different concentrations of hyperin.
Result: Hyperin could significantly inhibit CoCl2-induced cytotoxicity and apoptosis on PC12 cells in a dose-dependent manner, by inhibiting reactive oxygen species (ROS) production, increasing mitochondrial membrane potential (MMP), and inactivating caspase-3 and poly ADP-ribose polymerase (PARP).
Conclusion: Hyperin could inhibit CoCl2-induced cytotoxicity and apoptosis on PC12 cells, show neuroprotective effects on hypoxic/ischemic neural injuries.
