Cleavage of CAD inhibitor in CAD activation and DNA degradation during apoptosis

Various molecules such as cytokines and anticancer drugs, as well as factor deprivation, rapidly induce apoptosis (programmed cell death), which is morphologically characterized by cell shrinkage and the blebbing of plasma membranes and by nuclear condensation. Caspases, particularly caspase 3, are proteases that are activated during apoptosis and which cleave substrates such as poly(ADP-ribose) polymerase, actin, fodrin, and lamin. Apoptosis is...
