What is MOMP in apoptosis?
Mitochondrial outer membrane permeabilization (MOMP), also known as the mitochondrial outer membrane permeability, is one of two ways apoptosis (programmed cell death) can be activated. MOMP is known as the point of no return in apoptosis.
What does MOMP mean?
|MOMP||Mitochondrial Outer Membrane Permeabilization|
|MOMP||Major Outer Membrane Protein|
|MOMP||Mid-Ocean Meeting Point|
|MOMP||Maine Organic Milk Producers (Charleston, ME)|
How does permeability lead to cell death?
A loss of IMM permeability leads to rapid loss of the mitochondrial membrane potential (ΔΨmt) and the consequent loss of adenosine triphosphate (ATP) as well as osmotic shock to the organelle and rupture of the outer mitochondrial membrane (OMM).
Why is the outer membrane of mitochondria permeable?
The outer membrane has many protein-based pores that are big enough to allow the passage of ions and molecules as large as a small protein. In contrast, the inner membrane has much more restricted permeability, much like the plasma membrane of a cell.
What causes Momp?
The innocent bystander scenario suggests that MOMP is a very specific sort of mitochondrial damage, caused exclusively by BAX and BAK. Furthermore, numerous rigorous studies have demonstrated that cytochrome c release from mitochondria is complete and independent of caspase activation.
What causes opening of the MPTP?
Mitochondrial permeability transition pore (MPTP) is a transmembrane protein residing in the mitochondrial inner membrane. Normally closed, this large protein pore opens when stimulated by mitochondrial matrix Ca2+ accumulation, adenine nucleotide depletion, increased phosphate concentration or oxidative stress.
Why does the mitochondria have two membranes?
The double membrane found in mitochondria and chloroplasts appears to be a relic of the absorption of the prokaryotic bacteria by the eukaryotic host cells. The inner membrane, which now contains numerous folds, apparently came from the bacterial membrane, while the outer membrane came from the host cell itself.
What effect do caspases have?
Activation of caspases ensures that the cellular components are degraded in a controlled manner, carrying out cell death with minimal effect on surrounding tissues. Caspases have other identified roles in programmed cell death such as pyroptosis and necroptosis.
What does MOPP stand for in cancer treatment?
MOPP is a combination chemotherapy regimen used to treat Hodgkin lymphoma. The acronym is derived from the component drugs of the regimen: (M)ustargen (also known as mechlorethamine, chlormethine, mustine, nitrogen mustard, or MSD)

How is MOPP used to treat Hodgkin’s disease?
MOPP (chemotherapy) MOPP is a combination chemotherapy regimen used to treat Hodgkin’s disease. The treatment is usually administered in four week cycles, often for six cycles. MSD and VCR are administered intravenously, while procarbazine and prednisone are pills taken orally. A newer Hodgkin’s lymphoma treatment is ABVD .
