Cadmium-Induced Apoptosis in Primary Rat Cerebral …
2013/5/31· In the present study, we observed that Cd-induced apoptosis is associated with calcium-induced massive production of ROS, dissipation of ΔΨm, cleavage of caspase-9, caspase-3 and PARP. Collectively, our results demonstrate that Cd-induced apoptosis is mediated by calcium signaling pathway and calcium-mediated apoptosis occurs through the mitochondria-caspase signaling pathway.
