查询词典 permeability

The long-term opening of mitochondria permeability transition pore results in the release of cytochrome C, apoptosis inducing factors, Ca2+ and other apoptosis factors into cytoplasm, which can destruct the whole cell structure and function by activating the main member of apoptosis protein family——caspase, or destroying the intranuclear chromoplasm independently, or affecting other protein relying on Ca2+, and finally lead to the formation of apoptotic body.
