  Oxidative stress is a much-recognized phenomenon linked with the progression of Neurodegenerative Diseases (NDs) due to imbalances in redox homeostasis. Increasing evidence indicates that excessive Reactive Oxygen Species (ROS), impairing the physiological functions of neurons via inducing cell apoptosis, is the main cause of NDs. The drug candidates are required that can effectively protect neurons from oxidative stress insult to slow down the process of neurodegenerative diseases. In present study, we investigated the protective effect and the underlying mechanisms of berberine (BBR, an isoquinoline alkaloid isolated from the herb Rhizoma coptidis, against oxidative damage in PC12 cells. It was found that BBR was able to suppress hydrogen peroxide (H2O2)- induced cell death in PC12 cells. Flow cytometry revealed that BBR significantly reduced the apoptosis of PC12 cells exposed to H.. View More»
