The loss of cellular homeostasis balance is a character of tumor. The mitochondria (the intrinsic pathway) and the death receptors (the extrinsic pathway) are two major signal transduction pathways. With elucidation of the apoptotic molecular mechanism, some key proteins and genes related with apoptosis had been as the molecular targets for anticancer new drugs. There is the fundamental signficance to research further both apoptotic molecular mechanism and tumor therapy. [展开更多
