Field: Medicine › Endocrinology, Diabetes and MetabolismIllustrative exampleArea: type 2 diabetesTarget: GPR40 agonismStage: preclinical✦ AI inferred reasoning

Hypothesis

GPR40 agonism would boost glucose-stimulated insulin secretion without the hypoglycemia risk of sulfonylureas.

What failed

Efficacy was strong in rodent models but did not replicate in primate islet studies.

Why

Species-specific receptor expression patterns — rodent islets over-express GPR40 relative to primate and human islets.

Research ideas from this failure

Unvetted lead — read the papers

New hypotheses this failure suggests, each with a crucial experiment, a rival explanation of the original result, and the papers it rests on. Written by AI from paper titles and abstracts found on OpenAlex (and Europe PMC, for life and health sciences).

Not available for example entries: this one describes an invented experiment, and ideas built on it would be fiction.
