Myostatin-related muscle hypertrophy is a rare genetic condition characterized by reduced body fat and increased skeletal muscle size. [1] Affected individuals have up to twice the usual amount of muscle mass in their bodies, but increases in muscle strength are not usually congruent. [ 2 ]
Myostatin (also known as growth differentiation factor 8, abbreviated GDF8) is a protein that in humans is encoded by the MSTN gene. [6] Myostatin is a myokine that is produced and released by myocytes and acts on muscle cells to inhibit muscle growth. [7] Myostatin is a secreted growth differentiation factor that is a member of the TGF beta ...
The best approach to specifically achieve muscle growth remains controversial (as opposed to focusing on gaining strength, power, or endurance); it was generally considered that consistent anaerobic strength training will produce hypertrophy over the long term, in addition to its effects on muscular strength and endurance.
Myostatin, a member of the transforming growth factor superfamily, is a negative regulator of bone and muscle growth. It may also play a role in obesity, insulin resistance, cardiovascular disease, and chronic kidney disease. [1] [2]
A growth factor is a naturally occurring substance capable of stimulating cell proliferation, wound healing, and occasionally cellular differentiation. [1] Usually it is a secreted protein or a steroid hormone .

Growth hormone increases muscle protein synthesis and increases muscle mass, but does not lead to gains in strength and function in most studies. [42] This, and the similar lack of efficacy of its effector insulin-like growth factor 1 (IGF-1), may be due to local resistance to IGF-1 in aging muscle, resulting from inflammation and other age ...
Finally, the muscle fibers that form later arise from satellite cells. [4] Two genes significant in muscle fusion are Mef2 and the twist transcription factor. Studies have shown knockouts for Mef2C in mice lead to muscle defects in cardiac and smooth muscle development, particularly in fusion. [12] The twist gene plays a role in muscle ...
