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 ...
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. [11]
In 2022, a JAMA Network Open cohort study of 8,279 older adults found that low muscle mass was linked with a faster drop in executive function, which are a set of skills that allow you to plan and ...

ShutterstockIt's a known fact that as you age, you lose muscle mass. That's why it's imperative to know what you should and should not do in your daily routine. We spoke with Antonio Reyes, master ...
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.
Increased amount of myostatin portray deficiency in muscle development and increase of fat; on the other hand, smaller than normal amounts of myostatin greatly increase natural muscle mass, strength and decrease fat levels. There are no known health problems related to the myostatin mutations, and affected individuals are intellectually normal. [4]
