Cell death, a global phenomenon found throughout the animal kingdom, is a mechanism to maintain tissue homeostasis and for adaptation to changes in the environment [1,2]. Millions of cells die in our body daily- they succumb to stress and commit suicide by a mechanism referred to as cell death or apoptosis [2-4]. Under normal conditions cells are continuously replaced by new cells from the stemor progenitor- cells. For example, an optimum balance in shedding of dead cells from the skin and their replenishment by new ones maintain our health and hygiene. In this context, apoptosis is a mechanism to eliminate cells that are no longer useful. Apoptosis has also emerged as an important player during development when programmed cell death (PCD) is triggered to eliminate extra cells and to sculpt the final form of an organ. PCD is a crucial developmental process for the removal of problematic or unnecessary cells in multi cellular organisms [5,6].
