Apoptosis, a form of programmed cell death, plays a very crucial role in various physiological processes for maintaining the homeostasis. This process is characterized by membrane blebbing, nuclear condensation, DNA fragmentation and cell shrinkage. Any defect in this highly regulated process eventually leads to extended cell survival and could result in neoplastic cell expansion followed by genetic instability. The apoptotic machinery is mainly processed and regulated by various caspases, a family of cysteine proteases...
