epigenetics exercise training muscle SNPs PGC-1alpha

shared by Nathan Goodyear on 30 Nov 17 - No Cached

Oxidative slow-twitch type I fibres (henceforth briefly called ‘slow fibres’) contain MHC-Iβ. They use oxidative phosphorylation (OXPHOS) to generate ATP and are thus highly fatigue resistant and preferentially activated during endurance exercise. Slow fibres comprise high amounts of mitochondria, myoglobin and lipid droplets, and are well supplied by capillaries

there are three types of fast-twitch fibres (types IIA, IID/X, IIB, with the corresponding MHC isoforms IIa, IId/x, IIb) which are all used for rapid high-force generation. Oxidative-glycolytic fast-twitch type IIA fibres have intermediate amounts of mitochondria, lipid droplets and capillaries, and are intermediately resistant to fatigue (as compared to type I and types IIB and IID/X). Glycolytic fast-twitch type IID/X fibres are poor in mitochondria, lipids and capillaries and more susceptible to fatique than type IIA. Glycolytic fast-twitch type IIB fibres have the lowest amounts of mitochondria, lipid droplets and capillaries, but generate the highest contraction velocities

Those that carry the risk SNP for Gly482Ser for the PGC-1alpha gene dont' transform type II to type I and thus decrease the effectiveness of aeorbic exercise training, decreased oxidative phosphorylation, decreased lipid oxidation, increased lipid accumulaiton in muscle, and increased risk of IR, obesity, and diabetes.

only abstract available here. Weight loss, through diet and exercise, decreased proteins important to tumor angiogenesis; thus weight loss associated with a reduction in VEGF, PEDF, and PAI-1 may reduce cancer risk, particularly in the overweight and obese. This is all the result of inflammation originating from obesity.
