Recruitment of mitochondrial cyclophilin to the mitochondrial inner membrane under conditions of oxidative stress that enhance the opening of a calcium-sensitive non-specific channel.
1997), increases reactive oxygen species (ROS) production, impairs mitochondrial respiration, causes ATP depletion, opens the mitochondrial permeability transition pore and makes the mitochondrial inner membrane abruptly permeable to solutes up to 1500 Da Qames et al.
At the present time, mutations in at least 9 genes [POLG, [4] polymerase (DNA directed), gamma; DGUOK, deoxyguanosine kinase; TK2, thymidine kinase, mitochondrial; TYMP, thymidine phosphorylase; MPV17, MpV17 mitochondrial inner membrane protein; SUCLA2, succinate-CoA ligase, ADP-forming, beta subunit; SUCLG1, succinate-CoA ligase, alpha sub unit; RRM2B, ribonucleotide reductase M2 B (TP53 inducible); C10orf2, chromosome 10 open reading frame 2 (also known as TWINKLE)] have been found to cause mtDNA depletion (3-17).
Any impairment on the mitochondrial inner membrane structure and complex's activities could have catastrophic consequences due to mitochondrial dysfunction in energy metabolism.
CL is found almost exclusively in the mitochondrial inner membrane and plays a central role in mitochondrial oxidative phosphorylation because several respiratory chain complexes depend on CL (1,2).
pectinata leaves may not injure the mitochondrial inner membrane but decreases significantly the oxidative phosphorylation.
