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 ]
A monoclonal antibody specific to myostatin increases muscle mass in mice [40] and monkeys. [25] A two-week treatment of normal mice with soluble activin type IIB receptor, a molecule that is normally attached to cells and binds to myostatin, leads to a significantly increased muscle mass (up to 60%). [41]
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]
Weight loss over 60 can be difficult due to muscle loss and changes in metabolism. Here, doctors and dietitians share how to build strength and lose pounds.
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.

Myostatin, a TGF-beta superfamily member, is a negative regulator of muscle growth. [1] Myostatin binds to ACVR2B and to a lesser extent ACVR2A. In mice that were ACVR2A −/− mutants there was an increase in all four muscle groups studied (pectoralis, triceps, quadriceps, and gastrocnemious/plantaris muscles). [1] Two of these muscle groups ...
