Metformin ampk activation
Web24 aug. 2024 · Recently, surprising developments unfolded in the area of AMPK research when several studies pointed out that, under metabolic stress conditions, AMPK activators (metformin) suppress tumor growth by downregulating AMPK rather than through its activation. Therefore, AMPK aberrant activities have been linked to activation and … WebMetformin-dependent activation of AMPK classically inhibits mTORC1 via TSC/RHEB, but several lines of evidence suggest additional mechanisms at play in metformin inhibition of mTORC1. Here we investigated the role of direct AMPK-mediated serine phosphorylation of RAPTOR in a new Raptor AA mouse model, in which AMPK phospho-serine sites …
