Myostatin (GDF-8), a member of the TGFbeta superfamily, is a potent and specific negative regulator of skeletal muscle mass. In serum, myostatin circulates as part of a latent complex containing myostatin propeptide and follistatin-relatedgene. The myostatin propeptide is known to bind and inhibit myostatin in vitro. This interaction is relevant in vivo, with a majority (>70%) of myostatin in serum bound to its propeptide. The myostatin propeptide is negative regulator of myostatin in vivo.Description:28 kDa protein containing 243 amino acid residues of the human Myostatin Propeptide and 5 additional amino acid residues.
The gene encoding myostatin was discovered in 1997 by geneticists Se-Jin Lee and Alexandra McPherron who produced a strain of mutant mice that lack the gene. These myostatin "knockout" mice have approximately twice as much muscle as normal mice. These mice were subsequently named "mighty mice".
Naturally occurring deficiencies of myostatin have been identified in cattle by Ravi Kambadur, whippets, and humans; in each case the result is a dramatic increase in muscle mass. A mutation in the 3' UTR of the myostatin gene in Texel sheep creates target sites for the microRNAs miR-1 and miR-206. This is likely to cause the muscular phenotype of this breed of sheep.
Human myostatin consists of two identical subunits, each consisting of 109 (NCBI database claims human myostatin is 375 residues long) amino acid residues. Its total molecular weight is 25.0 kDa. The protein is inactive until a protease cleaves the NH2-terminal, or "pro-domain" portion of the molecule, resulting in the active COOH-terminal dimer.
Myostatin binds to the activin type II receptor, resulting in a recruitment of either coreceptor Alk-3 or Alk-4. This coreceptor then initiates a cell signaling cascade in the muscle, which includes the activation of transcription factors in the SMAD family - SMAD2 and SMAD3. These factors then induce myostatin-specific gene regulation. When applied to myoblasts, myostatin inhibits their differentiation into mature muscle fibers.
How does GDF-8 work?
Some studies show that the lack of myostatin gives rise to impressive results in the increase of muscle mass both in humans and in animals. In bones specifically, the lack of myostatin increases its mineral density, resulting in an increase of the calcium levels of the organism. GDF-8 is stored in bones and it is necessary for the correct functionality of the heart, muscles, and nerves as well as for blood clotting.
While using this recombinant myostatin propeptide, it was found that collagen-rich fibrous tissue was plentiful in the injured area of the individual's treated muscle, which has as a result the improvement of the regenerative capacity of the body.
Myostatin deficiency increases the ostegenic potential (formation of bone tissue) of bone marrow. There have been some studies related to the healing properties of stem cells originated in the bone marrow that has an auto regeneration capacity. This benefit can be promoted by blocking Myostatin on humans.
Myostatin inhibitors are used on muscular dystrophy treatment in the attempt to accomplish the muscle regeneration. Myostatin propeptide enhances muscle regeneration, increases myofiber hypertrophy (an increase in size of skeletal muscle through a growth in size of its component cells) and decreases fibrosis (formation of excess fibrous connective tissue, which can obliterate the function of the affected limb) in muscle healing.
