The study shows cadmium suppresses AMPK and that metformin restores AMPK activity, but the molecular mechanism by which cadmium inhibits AMPK remains unexplained. Understanding this upstream mechanism is critical for developing targeted interventions and predicting which heavy metals might trigger similar pathways.
