Mitochondria-controlled signaling mechanisms of brain protection in hypoxia
The article is focused on the role of the cell bioenergetic apparatus, mitochondria, involved in development of immediate and delayed molecular mechanisms for adaptation to hypoxic stress in brain cortex. Hypoxia induces reprogramming of respiratory chain function and switching from oxidation of NAD-related substrates (complex I) to succinate oxidation (complex II). Transient, reversible, compe...
متن کاملToxicity of atorvastatin on isolated brain mitochondria
Background: Although the bio kinetics, metabolism and chemical toxicity of Atorvastatin are well known, until recently little attention was paid to the potential neurotoxic effect of Atorvastatin (Atv). Regarding the concrete evidences indicating Atv may reduce Coenzyme Q10 (CoQ10) levels through blockage of metalonate cycle, the present work aims to determine if Atorvastatin may provide toxic...

متن کاملBrain Mitochondria
A mitochondrial fraction prepared from calf brain cortex possessed negligible glycolytic activity in the absence of the enzymes of the high speed supernatant fraction. When mitochondria were added to a supernatant system supplemented with optimal amounts of crystalline hexokinase, a 20 per cent stimulation of glycolysis was observed. The supernatant fraction produced minimal amounts of lactate ...
متن کاملBRAIN MITOCHONDRIA I. Isolation of Bovine Brain Mitochondria
Two methods of preparing a mitochondrial fraction from beef brain cortex are described. Data are presented on the rate of oxidation of substrates, P/O and respiratory control ratios, cholinesterase activity, and DNA content. Electron micrographs of isolated mitochondria and mitochondria in situ are shown. Comparisons are drawn between these preparations and mitochondria prepared in 0.25 M sucro...
