Coenzyme Q10 (CoQ10) protects retinal ganglion cells (RGCs) in experimental retinal ischemia and glaucoma by scavenging reactive oxygen species. We tested whether a diet supplemented with ubiquinol, the reduced form of CoQ10, promotes RGC survival and blocks the apoptotic pathway in ischemic mouse
We report a 3-year follow-up of high-dose ubiquinol supplementation in a case of familial multiple system atrophy (MSA) with compound heterozygous nonsense (R387X) and missense (V393A) mutations in COQ2. A high-dose ubiquinol supplementation substantially increased total coenzyme Q10 levels in
CONCLUSIONS
Traumatic nerve injury or nerve disease leads to denervation and severe muscle atrophy. Recent evidence shows that mitochondrial loss could be a key mediator of skeletal muscle atrophy. Here, we show that daily heat stress treatment rescues denervation-induced loss of mitochondria and
Inherited optic neuropathies (IONs) are neurodegenerative disorders characterized by optic atrophy with or without extraocular manifestations. Optic atrophy-10 (OPA10) is an autosomal recessive ION recently reported to be caused by mutations in RTN4IP1, which encodes reticulon 4 interacting protein
A nuclear gene (QCR9) encoding the 7.3-kDa subunit 9 of the mitochondrial cytochrome bc1 complex from Saccharomyces cerevisiae has been isolated from a yeast genomic library by hybridization with a degenerate oligonucleotide corresponding to nine amino acids proximal to the N terminus of purified
The conditions under which Coenzyme Q (CoQ) may protect platelet mitochondrial function of transfusional buffy coats from aging and from induced oxidative stress were investigated. The Pasteur effect, i.e. the enhancement of lactate production after inhibition of mitochondrial respiratory chain, was
Deterioration during seed storage generally causes seed vigour declining. However, the mechanism of deterioration occurred still not clear. Seeds and embryos of oat (Avena sativa L.) were selected to analyze the relation of physiological and metabolic reactions with DEGs by using RNA-seq. Oat seed
The substitutions M1401, F144S and L, G152S, T163A and V333A in cytochrome b of the ubiquinol-cytochrome c oxidoreductase (bc1 complex) from Rhodobacter capsulatus provide resistance to the quinol oxidation (Qo) inhibitors myxothiazol, mucidin and stigmatellin. Site-directed mutagenesis with
Age-associated alterations in the mitochondrial electron transport system (ETS) may lead to free radical generation and contribute to aging. The complexes of the ETS were screened spectrophotometrically in gastrocnemius of young (10 month) as well as older (20 and 26 month) B6C3F1 female mice fed an
The aim of this study is to determine whether coenzyme Q (CoQ) muscle concentrations and redox state are associated with pathologic changes in muscle biopsy specimens. Skeletal muscle biopsies were collected (January 2002-February 2004) and underwent pathologic evaluation. Quadriceps specimens (n =
The progressive loss of skeletal muscle mass is a serious pathophysiological problem in the elderly, which warrants detailed biochemical studies into the underlying mechanism of age-related fiber degeneration. Over the last few years, mass spectrometry (MS)-based proteomics has identified a
Mitochondria are dynamic intracellular organelles playing a central role in cell metabolism by generating ATP, through the oxidative phosphorylation system (OXPHOS). Altered mitochondrial functions have been identified as causative or contributing factors in some degenerative diseases and are
The effects of vitamin E on lipid peroxidation, intracellular free Ca2+ concentration ([Ca2+]i), and cell death were investigated in the postischemic immature cerebellum. Deprivation of oxygen and glucose for 10-min in a suspension of freshly dissociated granule cells from the cerebellum of
Mitochondria isolated from the skeletal muscle of an infant with mitochondrial myopathy and renal dysfunction were analyzed. Activities of NADH dehydrogenase, succinate dehydrogenase, ubiquinol-cytochrome c oxidoreductase, and cytochrome c oxidase were severely decreased. Cytochromes aa3 and b were
