The SINE Of A Winning Thoroughbred
A research team led by Plusvital’s CSO, Prof Emmeline Hill, have today published a scientific paper that identifies the specific mutation in the Speed Gene that causes the change in muscle growth in the Thoroughbred. This variation in muscle growth and muscle fibre type differentiation manifests itself on the track in terms of the optimum race distance for a horse.
Thoroughbred horses are finely-tuned athletes with a high aerobic capacity relative to skeletal muscle mass, attributable to centuries of genetic selection for speed and stamina. Polymorphisms in the myostatin gene, a pronounced inhibitor of skeletal muscle growth, have been shown to almost singularly account for gene-based race distance aptitude in racehorses, earning the myostatin gene the moniker of “Speed Gene”.
