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 ...
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 ]
Double-muscled cattle are breeds of cattle that carry one of seven known mutations that limits and reduces the activity of the myostatin protein. Normally, myostatin limits the number of muscle fibers present at birth, and interfering with activity of this protein causes animals to be born with higher numbers of muscle fibers, consequently augmenting muscle growth.
The active-myostatin gene acts as a "governor" on muscle growth; myostatin is a protein that instructs muscles to stop growing. In effect, when inactive, as it is with Piedmontese cattle, it no longer prevents muscle development which is what allows for the hypertrophic condition sometimes referred to as "double muscling". [7]
The Belgian Blue has a natural mutation in the myostatin gene which codes for the protein, myostatin ("myo" meaning muscle and "statin" meaning stop). [7] Myostatin is a protein that inhibits muscle development. This mutation also interferes with fat deposition, resulting in very lean meat. [7]
Myostatin inhibitors were generally able to increase lean body mass and reduce body fat in people with sarcopenia, but the extent to which this translated into functional improvements varied. [ 11 ] Bimagrumab showed effectiveness in increasing lean mass and reducing fat mass in obese individuals in a clinical trial.
The definition and use of the term myokine first occurred in 2003. [5] In 2008, the first myokine, myostatin, was identified. [4] [6] The gp130 receptor cytokine IL-6 (Interleukin 6) was the first myokine found to be secreted into the blood stream in response to muscle contractions.
The deficiency occurs in the cytosol of the muscle cell. Fatty acid metabolism disorder (fatty acid oxidation disorder, FAOD)—defect in fat (lipid) metabolism, anywhere along the pathway, starting from entering the muscle cell and ending at converting fatty acids into acetyl-CoA within the mitochondrion.
