Investigation of GDF8 Gene Promoter in Iranian Sheep
Myostatin is a growth factor belonging to the TGFß superfamily. TGFß growth factors are active in the regulation of embryonic development and in tissue homeostasis in adults. Myostatin is a growth factor controlling proliferation of myoblasts in embryonic development. Mutations in coding sequences of the bovine myostatin (GDF8) gene lead to muscle hyperplasia suggesting its inhibitory function ...
متن کاملEffect of Eight Weeks of Resistance Training on Myostatin and Folistatin Proteins Content in Gastrocnemius Muscle Tissue of Elderly Rats
Introduction: Myostatin and follistatin proteins are key proteins in the regulation of muscle atrophy and hypertrophy. Aging and sarcopenia can lead to disruption of cellular mechanisms and the activity of these proteins. Therefore, the aim of the present study was to investigate the effect of eight weeks of resistance training on myostatin and folistatin proteins content in Gastrocnemius muscl...
متن کاملThe role of myostatin in muscle wasting: an overview
Myostatin is an extracellular cytokine mostly expressed in skeletal muscles and known to play a crucial role in the negative regulation of muscle mass. Upon the binding to activin type IIB receptor, myostatin can initiate several different signalling cascades resulting in the upregulation of the atrogenes and downregulation of the important for myogenesis genes. Muscle size is regulated via a c...
متن کاملMyostatin in the Pathophysiology of Skeletal Muscle
Myostatin is an endogenous, negative regulator of muscle growth determining both muscle fiber number and size. The myostatin pathway is conserved across diverse species ranging from zebrafish to humans. Experimental models of muscle growth and regeneration have implicated myostatin as an important mediator of catabolic pathways in muscle cells. Inhibition of this pathway has emerged as a promis...
متن کاملMyostatin regulates cardiomyocyte growth through modulation of Akt signaling.
Myostatin is a highly conserved, potent negative regulator of skeletal muscle hypertrophy in many species, from rodents to humans, although its mechanisms of action are incompletely understood. Transcript profiling of hearts from a genetic model of cardiac hypertrophy revealed dramatic upregulation of myostatin, not previously recognized to play a role in the heart. Here we show that myostatin ...
