Mechanisms of ER Stress-Mediated Mitochondrial Membrane Permeabilization
During apoptosis, the process of mitochondrial outer membrane permeabilization (MOMP) represents a point-of-no-return as it commits the cell to death. Here we have assessed the role of caspases, Bcl-2 family members and the mitochondrial permeability transition pore on ER stress-induced MOMP and subsequent cell death. Induction of ER stress leads to upregulation of several genes such as Grp78, ...
متن کاملMitochondrial membrane permeabilization in cell death.
Irrespective of the morphological features of end-stage cell death (that may be apoptotic, necrotic, autophagic, or mitotic), mitochondrial membrane permeabilization (MMP) is frequently the decisive event that delimits the frontier between survival and death. Thus mitochondrial membranes constitute the battleground on which opposing signals combat to seal the cell's fate. Local players that det...
متن کاملNanosecond electric pulses cause mitochondrial membrane permeabilization in Jurkat cells.
Nanosecond, high-voltage electric pulses (nsEP) induce permeabilization of the plasma membrane and the membranes of cell organelles, leading to various responses in cells including cytochrome c release from mitochondria and caspase activation associated with apoptosis. We report here evidence for nsEP-induced permeabilization of mitochondrial membranes in living cells. Using three different met...
متن کاملMitochondrial shape governs BAX-induced membrane permeabilization and apoptosis.
Proapoptotic BCL-2 proteins converge upon the outer mitochondrial membrane (OMM) to promote mitochondrial outer membrane permeabilization (MOMP) and apoptosis. Here we investigated the mechanistic relationship between mitochondrial shape and MOMP and provide evidence that BAX requires a distinct mitochondrial size to induce MOMP. We utilized the terminal unfolded protein response pathway to sys...
متن کاملApoptosis: Mitochondrial Membrane Permeabilization – The (W)hole Story?
One critical step of apoptosis is the release of mitochondrial proteins through the outer mitochondrial membrane. Recent work shows that two pro-apoptotic Bcl-2 family proteins, Bax and Bid, as well as the mitochondrion-specific lipid cardiolipin may cooperate in chemically defined liposomes to generate a protein-permeable conduit, relaunching the debate on the identity of the pore responsible ...
