mitochondrial myopathies/obesity

Leigh's syndrome, which is characterised by progressive neurodegeneration involving the brainstem and basal ganglia, belongs to a family of disorders classified as mitochondrial myopathies. It is most commonly transmitted by an autosomal recessive mode of inheritance, but can sometimes occur in a

Endurance exercise training induces an increase in the respiratory capacity of muscle, resulting in an increased capacity to generate ATP as well as improved efficiency of muscle contraction. Such adaptations are largely the result of a coordinated genetic response that increases mitochondrial

Long-chain fatty acids (LCFA) and thiazolidinediones are potent activators of differentiation of preadipose cells. These adipogenic effects are, at least in part, mediated by nuclear receptors of the peroxisome proliferator-activated receptor (PPAR) subfamily. This report describes the effects of

Myostatin, a member of the muscle-specific transforming growth factor (TGF)-β family, negatively regulates skeletal muscle growth. It inhibits muscle stem cell proliferation and differentiation and attenuates adult muscle fiber protein accretion, resulting in decreased skeletal muscle mass. As such,

The NAD⁺ precursor nicotinamide riboside (NR) is a type of vitamin B₃ found in cow's milk and yeast-containing food products such as beer. Recent studies suggested that NR prevents hearing loss, high-fat diet-induced obesity,

Hydrogen sulfide (H2S) is a novel endogenous gaseous signal transducer (gasotransmitter). Its emerging role in multiple facets of inter- and intra-cellular signaling as a metabolic, inflammatory, neuro and vascular modulator has been increasingly realized. Although H2S is known for its effects as an
