What is ACE-031 peptide?

ACE-031 is a synthetic protein made up of activin receptor type IIB and the immunoglobulin G1-Fc (IgG1-Fc). It binds to myostatin and related proteins within muscle, rendering them inactive.

Are myostatin inhibitors illegal?

Myostatin inhibitors can improve athletic performance and therefore there is a concern these inhibitors might be abused in the field of sports. Myostatin inhibitors are specifically banned by the World Anti-Doping Agency (WADA).

Are myostatin inhibitors permanent?

Their misguided focus continues to be on blocking myostatin completely with unnatural synthetic drugs. These experimental medications have yet to become available and, due to the fact that they are irreversible blockers, may have potentially harmful side effects.

Which drugs is a myostatin inhibitor?

Myostatin inhibitors in development

• RG6206. RG6206 (also known as RO7239361 or BMS986089) is an investigational molecule to possibly treat Duchene muscular dystrophy (DMD).
• ACE-083.
• Domagrozumab (PF-06252616)

What does myostatin do in the body?

Myostatin is found almost exclusively in muscles used for movement (skeletal muscles), where it is active both before and after birth. This protein normally restrains muscle growth, ensuring that muscles do not grow too large.

How do you take Ace-031?

ACE-031 1 mg can be dissolved by adding 1 ml of water to provide 1 mg of ACE-031 in every 1 ml of solution. This solution can be injected in one single dose for maximum efficacy or split into several smaller doses.

What happens if you have too much myostatin?

High levels of myostatin make it hard for the body to build muscle, and low levels of myostatin allow muscle to grow. After the mice and cattle discovery, scientists found natural mutations in some dogs and sheep, but never in a human until 2004.

How do I know if I have myostatin deficiency?

Myostatin-related muscle hypertrophy is diagnosed based upon the clinical signs and symptoms in the patient (i.e, reduced body fat and increased muscle size) and genetic testing . Body fat can be measured by ultrasound or with a caliper.

Are myostatin inhibitors bad for you?

Now, a new University of Michigan study in mice suggests that while myostatin inhibitors may indeed bulk up muscles, they may also bring a troubling side effect — small, brittle tendons that could make muscle injuries more likely.

Can myostatin be blocked?

In vivo, myostatin-specific activation-blocking antibodies were able to prevent atrophy in a corticosteroid atrophy model, and also increased muscle mass and function in healthy animals.

Is myostatin deficiency bad?

This condition is not known to cause any medical problems, and affected individuals are intellectually normal. Myostatin-related muscle hypertrophy is caused by mutations in the MSTN gene . It follows an incomplete autosomal dominant pattern of inheritance.

What is myostatin good for?

Myostatin (MSTN), also referred to as growth and differentiation factor-8, is a protein secreted in muscle tissues. Researchers believe that its primary function is in negatively regulating muscle because a mutation in its coding region can lead to the famous double muscle trait in cattle.
