What was studied?
Plasma stability, pancreatic-cell assays, isolated islets and mouse metabolic experiments compared three kisspeptin lengths.
What did the researchers report?
The isoforms differed in degradation and cellular effects. Acute glucose elevation occurred in the mouse experiments, and favorable cell findings did not translate uniformly to glucose tolerance.
What are the limits?
Sequence length changes biological behavior. The results do not establish diabetes treatment, and a selected favorable endpoint should not obscure unfavorable or neutral metabolic findings.
