The Claim

Myostatin is expressed in the synovial tissue of patients with rheumatoid arthritis.

Source: Myostatin is a direct regulator of osteoclast differentiation and its inhibition reduces inflammatory joint destruction in mice

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Description
1 study reviewed
In plain English

Myostatin protein is present in the joint lining tissue of people with rheumatoid arthritis.

See the scientific wording

Myostatin is expressed in the synovial tissue of patients with rheumatoid arthritis, suggesting a potential role in human disease beyond its known function in muscle regulation.

Why this might work

Inflamed joint tissue produces myostatin, which activates a signaling chain in bone-resorbing cells, causing them to multiply and break down bone, leading to joint damage.

  1. Study: Myostatin is a direct regulator of osteoclast differentiation and its inhibition reduces inflammatory joint destruction in mice

    Scientists found that a protein called myostatin, which usually controls muscle growth, is also present in the swollen joints of people with rheumatoid arthritis. This suggests it might help cause joint damage in arthritis, not just affect muscles.
