  1. Mitochondrial fission

    Mitochondria can divide by fission and since they require mitochondrial DNA for their function, fission is coordinated with Mitochondrial DNA Replication DNA replication . Some of the proteins that are involved in mitochondrial fission have been identified and some of them are associated with mitochondrial disease s. ref Cite pmid 21776419 ref Mechanism The DNM1L Drp1 protein is a member of the Dynamin family of large GTPases . Drp1 controls the final part of mitochondrial fission, pinching off the membrane stalk between two forming daughter mitochondria. The MFN2 protein is part of a complex that links the endoplasmic reticulum ER to mitochondria. Points of ER mitochondrial association have been associated with the formation of Drp1 complexes and mitochondrial fission. ref Cite pmid 21885730 ref Several Drp1 binding proteins have been identified. ref Cite pmid 21772324 ref A protein called mitochondrial fission factor Mff binds Drp1 and promotes mitochondrial fission. ref Cite pmid 21149567 ref The FIS1 protein might recruit Drp1 to sites of fission ref Cite pmid 21647385 ref but it might require association with another protein, MIEF1 coded for by the SMCR7L gene , to promote mitochondrial fission.

  1. Mitochondrial biogenesis

    Mitochondrial biogenesis is the process by which new mitochondria are formed in the cell. Mitochondrial biogenesis is activated by numerous different signals during times of cellular stress or in response to environmental stimuli. The mitochondrion is a key regulator of the metabolic activity of the cell, and is also an important organelle in both production and degradation of free radicals. It is thought that higher mitochodrial copy number or higher mitochondrial mass is protective for the cell. Mitochondria are produced from the transcription and translation of genes both in the nuclear genome and in the Mitochondrial DNA mitochondrial genome . The majority of mitochondrial protein comes from the nuclear genome, while the mitochondrial genome encodes most parts of the electron transport chain along with mitochondrial rRNA and tRNA . A major adaptation to mitochondrial biogenesis results in more mitochondrial tissues which increases metabolic enzymes for glycolysis, oxidative phosphorylation and ultimately a greater mitochondrial metabolic capacity. Peter D. Wagner Summer 2011 Lecture cn date October 2011 The master regulators of mitochondrial biogenesis appear to be the peroxisome proliferator activated receptor gamma PGC family of transcriptional coactivators, including PPARGC1A PGC 1 , PPARGC1B PGC 1 , and the PGC related coactivator, PRC. PGC 1 , in particular, is thought to be a master regulator. It is known to co activate nuclear respiratory factor 2 GABPA NRF2 GABPA , and together with NRF 2 coactivates nuclear respiratory factor 1 NRF1 . The NRFs, in turn, activate the mitochondrial transcription factor A TFAM tfam , which is directly responsible for transcribing nuclear encoded mitochondrial proteins. This includes both structural mitochondrial proteins as well as those involved in Human mitochondrial genetics Replication.2C repair.2C transcription.2C and translation mtDNA transcription, translation, and repair .

  1. Mitochondrial toxicity

    Mitochondrial toxicity is a condition in which the mitochondrion mitochondria of a body s cells become damaged or decline significantly in number it occurs as a side effect of certain antiretroviral drug s used to treat human immunodeficiency virus, or HIV . Causes While the exact causes of mitochondrial toxicity are not known, research has shown that a certain group of anti viral drugs used to treat HIV, specifically nucleoside analog reverse transcriptase inhibitor s NRTIs , interfere with an enzyme needed in the production of mitochondria. ref http www.thebody.com pinf mitochondrial.html ref Symptoms The disruption of cell function that accompanies the condition can cause both mild and severe problems in people suffering from mitochondrial toxicity. The most commonly observed symptom is muscle weakness, or myopathy . Others include peripheral neuropathy numbness in the fingers and toes and pancreatitis inflammation of the pancreas , with the most severe being lactic acidosis , in which a build up of lactic acid in the tissues of the body leads to loss of energy, organ failure, and eventually death. ref http www.projinf.org fs mito b.html ref References references External links Mitochondrial toxicity at http www.hivnet.org OverHivEnAids Alternatief BrochureBijwerkingenEngels Mitochondrial 20toxicity.htm hiv.org Category Toxicology medical stub med toxic stub sl Mitohondrijska toksi nost ...   more details

PBC is an autoimmune disorder , a condition in which the human body s immune defense system mistakenly attacks the body s own cells, or in this case parts of the cells. Cause of AMAs is postulated that xenobiotic induced and or oxidative modification of mitochondrial autoantigens is a critical step leading to loss of tolerance.

    Unreferenced date December 2009 image Mitochondrie.svg thumb 300px Mitochondria structure br 1 Inner membrane br 2 Outer membrane br 3 Crista br 4 Matrix biology Matrix The outer mitochondrial membrane , which encloses the entire organelle, has a protein to phospholipid ratio similar to the eukaryotic plasma membrane about 1 1 by weight . It contains numerous integral protein s called Porin protein porin s , which contain a relatively large internal channel about 2 3 Nanometre nm that is permeable to all molecules of 5000 Atomic mass unit dalton s or less. Larger molecules can only traverse the outer membrane by active transport through mitochondrial membrane transport protein s. The outer membrane also contains enzyme s involved in such diverse activities as the elongation of fatty acid s, oxidation of epinephrine adrenaline , and the Biodegradation degradation of tryptophan .

  1. Inner mitochondrial membrane

    Image Mitochondrie.svg thumb 300px right Mitochondria structure 1 inner membrane, 2 outer membrane, 3 cristae, 4 matrix The mitochondria l inner membrane forms internal compartments known as crista e, which allow greater space for the proteins such as cytochrome s to function properly and efficiently. The electron transport chain is located on the inner membrane of the mitochondria. Within the inner mitochondrial membrane are also transport protein s that transport in a highly controlled manner metabolites across this membrane. The inner membrane of mitochondria IMM is similar in lipid composition to the membrane of bacteria . This phenomenon can be explained by the endosymbiont hypothesis of the origin of mitochondria as prokaryotes internalized by a eukaryotic host cell.
