A significant positive correlation between in-situ active caspase-3 in the sperm midpiece and DNA fragmentation was observed in the low motility fractions of patients. A soluble proform of caspase 3 containing a fortuitous mutation (W206R) is inactive when incubated with recombinant human caspase 8 and therefore can serve as a useful reagent to test the efficacy of caspase 8 inhibitors.

The antiapoptotic property of Hualpha-Syn in neuronal cell lines is associated with the attenuation of caspase-3 activity without affecting the caspase-9 activity or the levels of cleaved, active caspase-3. The apoptosis resistance of mdr cells is not related to the abnormality of CPP32 but the upstream of caspase, the fact of which indicates promising prospect of the research on reversion of mdr cells using CPP32 as target. The crystal structure of the binding site of caspase-3 reveals critical side chain movements in a hydrophobic pocket. The positions of these side chains may have implications for the directed design of inhibitors of caspase-3 or caspase-7. The increased ratio of Bax/Bcl-2 proteins after Epigallocatechin-3-gallate may lead to activation of caxpaxe-3, leading to apoptosis.

This gene encodes a protein which is a member of the cysteine-aspartic acid protease (caspase) family. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis. Caspases exist as inactive proenzymes which undergo proteolytic processing at conserved aspartic residues to produce two subunits, large and small, that dimerize to form the active enzyme. This protein cleaves and activates caspases 6, 7 and 9, and the protein itself is processed by caspases 8, 9 and 10. It is the predominant caspase involved in the cleavage of amyloid-beta 4A precursor protein, which is associated with neuronal death in Alzheimer's disease. Alternative splicing of this gene results in two transcript variants that encode the same protein. Transfected caspase-3 is involved in the reduction of Akt level, and its involvement is mediated through caspase-9 activation.
