Mitochondrial biogenesis is the process by which cells increase mitochondrial numbers. [ 1 ] [ 2 ] It was first described by John Holloszy in the 1960s, when it was discovered that physical endurance training induced higher mitochondrial content levels, leading to greater glucose uptake by muscles. [ 3 ]
Mitophagy in yeast was first presumed after the discovery of Yeast Mitochondrial Escape genes (yme), specifically yme1. Yme1 like other genes in the family showed increase escape of mtDNA, but was the only one that showed an increase in mitochondrial degradation.
Mitochondrial replication is controlled by nuclear genes and is specifically suited to make as many mitochondria as that particular cell needs at the time. Mitochondrial transcription in humans is initiated from three promoters , H1, H2, and L (heavy strand 1, heavy strand 2, and light strand promoters).
Mitochondrial dynamics in different cells are understood by the way in which these proteins regulate and bind to each other. [2] These GTPases in control of mitochondrial fusion are well conserved between mammals, flies, and yeast. Mitochondrial fusion mediators differ between the outer and inner membranes of the mitochondria.
Molecular contributors to ageing (reactive oxygen species, mitochondrial unfolded protein response, mitochondrial metabolites, damage-associated molecular patterns, mitochondrial-derived peptides, mitochondrial membrane) Mitochondria are thought to be organelles that developed from endocytosed bacteria which learned to coexist inside ancient cells
Mitochondrial replacement therapy (MRT), sometimes called mitochondrial donation, is the replacement of mitochondria in one or more cells to prevent or ameliorate disease. MRT originated as a special form of in vitro fertilisation in which some or all of the future baby's mitochondrial DNA (mtDNA) comes from a third party.
Horizontal transfer of mitochondria is mediated by actin-rich membrane protrusions named tunneling nanotubes (TNTs). [5] The establishment of a nanotube begins with the formation of a filopodium-like membrane protrusion that retracts after reaching the recipient cell, leaving an ultrafine structure that is separated from the substrate. [1]
The glycerol phosphate shuttle was first characterized as a major route of mitochondrial hydride transport in the flight muscles of blow flies. [5] [6] It was initially believed that the system would be inactive in mammals due to the predominance of lactate dehydrogenase activity over glycerol-3-phosphate dehydrogenase 1 (GPD1) [5] [7] until high GPD1 and GPD2 activity were demonstrated in ...
