Does YK-11’s follistatin signal demonstrate human muscle growth?
Demonstrated findings
In mouse-derived C2C12 cells, YK11 increased follistatin expression and myogenic differentiation. Blocking follistatin reduced that response.
What might this mean? · interpretation
The experiment supports a follistatin-linked mechanism in this cell model.
What might this mean, and what would change the interpretation?
Cell differentiation is not a measured increase in human muscle mass or strength. Exposure and downstream effects in people remain separate questions.
What would clarify this: Replication, animal functional outcomes and appropriately controlled human studies.
Mechanism to possible human relevance
- Working explanation
- The follistatin response offers a possible link between androgen-receptor signaling and differentiation in the tested cells.
- Possible human implication, hypothesis
- Muscle growth is a hypothesis to investigate, not an outcome measured in this experiment.
- Evidence that would support it
- Independent replication followed by appropriate in vivo muscle-size and function findings.
- Evidence that would challenge it
- Failure to reproduce the response or no muscle/function benefit at a tolerable exposure.
