Mitochondrial disease is a group of disorders caused by mitochondrial dysfunction. Mitochondria are the organelles that generate energy for the cell and are found in every cell of the human body except red blood cells .
Mitochondrial toxicity is a condition in which the mitochondria of a body's cells become damaged or decline significantly in number; it occurs as a side effect of certain antiretroviral drugs used to treat human immunodeficiency virus, or HIV.
Mitochondrial myopathies are types of myopathies associated with mitochondrial disease. [1] Adenosine triphosphate (), the chemical used to provide energy for the cell, cannot be produced sufficiently by oxidative phosphorylation when the mitochondrion is either damaged or missing necessary enzymes or transport proteins.
Mitochondrial dysfunction causes intestinal tissue damage For this study, researchers used a mouse model where a specific gene segment was deleted, disrupting their mitochondrial function.
The serious symptoms of Reye syndrome appear to result from damage to cellular mitochondria, [14] at least in the liver, and there are a number of ways that aspirin could cause or exacerbate mitochondrial damage. A potential increased risk of developing Reye syndrome is one of the main reasons that aspirin has not been recommended for use in ...
MELAS is a condition that affects many of the body's systems, particularly the brain and nervous system (encephalo-) and muscles (myopathy). In most cases, the signs and symptoms of this disorder appear in childhood following a period of normal development. [4]
A novel drug molecule that activates a key protein in the brain that cleans up and recycles damaged mitochondria may offer hope for young Parkinson's patients, a new study suggests.
Another damaging result of excess calcium in the cytosol is the opening of the mitochondrial permeability transition pore, a pore in the membranes of mitochondria that opens when the organelles absorb too much calcium. Opening of the pore may cause mitochondria to swell and release reactive oxygen species and other proteins that can lead to ...
