AIF deficiency compromises oxidative phosphorylation.
Apoptosis-inducing factor (AIF) is a mitochondrial flavoprotein that, after apoptosis induction, translocates to the nucleus where it participates in apoptotic chromatinolysis. Here, we show that human or mouse cells lacking AIF as a result of homologous recombination or small interfering RNA exhibit high lactate production and enhanced dependency on glycolytic ATP generation, due to severe red...
متن کاملSuppression of Mic60 compromises mitochondrial transcription and oxidative phosphorylation
Precise regulation of mtDNA transcription and oxidative phosphorylation (OXPHOS) is crucial for human health. As a component of mitochondrial contact site and cristae organizing system (MICOS), Mic60 plays a central role in mitochondrial morphology. However, it remains unclear whether Mic60 affects mitochondrial transcription. Here, we report that Mic60 interacts with mitochondrial transcriptio...
متن کاملTargeted Deletion of AIF Decreases Mitochondrial Oxidative Phosphorylation and Protects from Obesity and Diabetes
Type-2 diabetes results from the development of insulin resistance and a concomitant impairment of insulin secretion. Recent studies place altered mitochondrial oxidative phosphorylation (OxPhos) as an underlying genetic element of insulin resistance. However, the causative or compensatory nature of these OxPhos changes has yet to be proven. Here, we show that muscle- and liver-specific AIF abl...
متن کاملMutant mitochondrial elongation factor G1 and combined oxidative phosphorylation deficiency.
Although most components of the mitochondrial translation apparatus are encoded by nuclear genes, all known molecular defects associated with impaired mitochondrial translation are due to mutations in mitochondrial DNA. We investigated two siblings with a severe defect in mitochondrial translation, reduced levels of oxidative phosphorylation complexes containing mitochondrial DNA (mtDNA)-encode...
متن کاملThe effect of magnesium deficiency on oxidative phosphorylation.
The uncoupling of oxidative phosphorylation in mitochondrial preparations by thyroxine and its reversal are now well known (l-6). More recently we have shown that high levels of dietary magnesium completely prevent the uncoupling effect on heart mitochondria of thyroxine-fed animals, and partially overcome the growth inhibition caused by thyroxine. Thyroxine thus raises the magnesium requiremen...
