The Claim
Myostatin is highly expressed in the synovial tissue of individuals with rheumatoid arthritis and promotes osteoclast differentiation in vitro through SMAD2-dependent upregulation of NFATC1, contributing to joint bone destruction in mouse models of inflammatory arthritis.
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.
Myostatin protein is present at high levels in the joint lining of people with rheumatoid arthritis and drives the formation of bone-destroying cells in laboratory cell cultures via a specific molecular pathway, leading to bone loss in mice with inflammatory arthritis.
See the scientific wording
Myostatin is highly expressed in the synovial tissue of individuals with rheumatoid arthritis and promotes osteoclast differentiation in vitro through SMAD2-dependent upregulation of NFATC1, contributing to joint bone destruction in mouse models of inflammatory arthritis.
In inflamed joints, a protein called myostatin binds to receptors on bone-eating cells, turning on a signaling chain that moves a key gene regulator into the cell nucleus. This regulator turns on genes that make the bone-eating cells grow and break down bone, leading to joint damage.
What the research says
1 studyIn people and mice with rheumatoid arthritis, a protein called myostatin is found in swollen joints and makes bone-eating cells work faster, which damages the joints. When scientists blocked myostatin, the joint damage got better.
