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

How it works

1 study reviewed

In plain English

Myostatin has a similar structure to other proteins in the TGF-beta family, and blocking myostatin without targeting it specifically causes unintended effects on those related proteins.

See the scientific wording

Myostatin shares structural homology with other TGF-beta family proteins, leading to off-target effects when inhibited non-selectively.

Why this might work

When a drug blocks myostatin, it also accidentally blocks other similar proteins because they all look alike and use the same signaling system. This causes unintended changes in bone and tissue remodeling, since those other proteins normally control those processes too.

Study: Myostatin is a direct regulator of osteoclast differentiation and its inhibition reduces inflammatory joint destruction in mice
Blocking myostatin can help with arthritis, but since myostatin looks a lot like other similar proteins in the body, stopping it might accidentally affect those other proteins too — even if this study didn’t prove it directly.
