Western blot analysis was done after the drug treatment in HCN-2 adult neuronal cell culture. The caspase-9 antibody was used to identify the amount apoptotic protein in the culture. β-actin was as loading control. Density values, normalized to actin signals, are expressed as mean ± SD (n = 3) and are showed as arbitrary units. Significant different values are taken as P < 0.05.
