Caspase 3. Activated Caspase 3 is potent effector of post-treatment cell apoptosis: For the intrinsic cell death pathway, apoptosis is triggered by intracellular events such as DNA damage and oxidative stress. For the extrinsic cell death pathway, apoptosis is triggered by extracellular stimuli such as TNF and TRAIL. A sharp increase in the levels of Caspase 3 indicates the beginning of apoptosis.
