Apoptosis,,a wide physiological process in multicel-lular organisms, is critical for the organ development, the cell senescence, the tissue homeostasis and the resistance to infection of virus and bacteria. Apoptosis plays a key role in the regulation of the growth cell number such as the tissue construction, the elimination of abnormal or dangerous cells. Therefore, apoptosis is a stringent and effective cell quality controlling system, which reduces the number of harmful cells to the maximum, such as auto-immunity cell, cells infected by virus, tumor cells by cell suicide111. Apoptosis can be initiated by a wide variety of the extracellular and intracellular stimuli, including the developmental signals, the cellular stress and the disruption of cell cycle, transduced and amplified by the second messengers, and finally finished by the activating death effector protease. This process can be called apoptosis signal network. The defective in control of the apoptotic pathways may contribute to a variety of
