Necrosis, once thought accidental, may be programmed, involving the mitochondrial pore. This programmed necrosis contributes to cardiac disease, distinct from apoptosis.
Area of Science:
- Cardiovascular Biology
- Cell Death Mechanisms
- Molecular Cardiology
Background:
- Apoptosis (programmed cell death) is well-defined.
- Necrosis has traditionally been viewed as accidental cell death.
- Emerging evidence suggests necrosis can be a regulated, programmed process.
Purpose of the Study:
- To review the roles of necrosis and apoptosis in cardiac disease pathogenesis.
- To discuss the function of the mitochondrial permeability transition pore in programmed necrosis.
- To differentiate programmed necrosis from apoptosis in the context of cardiac pathology.
Main Methods:
- Literature review of programmed necrosis and apoptosis.
- Analysis of the role of the mitochondrial permeability transition pore.
- Synthesis of current data on cell death pathways in cardiac disease.
Main Results:
- Necrosis is increasingly recognized as a programmed cell death pathway.
- The mitochondrial permeability transition pore is implicated as a key mediator of necrotic cell death.
- Distinct roles for apoptosis and programmed necrosis in cardiac disease are being elucidated.
Conclusions:
- Programmed necrosis, mediated by factors like the mitochondrial pore, plays a significant role in cardiac disease.
- Understanding the nuances between apoptosis and necrosis is crucial for developing targeted cardiac therapies.
- Further research into necrotic pathways may reveal novel therapeutic strategies for heart conditions.

Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...

Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
