CASP3 and cancer: The mode of action of CASP3 is that when cells are damaged, it mainly shows mitochondrial membrane damage, and cytochrome in mitochondria is released to the outside of cells, which activates CASP3 and induces apoptosis.[19] CASP3 has attracted more and more attention as a target for the treatment of some cancers, and the study of CASP3 inhibitors is one of the effective methods for the development of anticancer drugs.
