GLP-1RAs exert their therapeutic effects through complex intracellular signaling pathways, specifically activating ERK1/2, AMPK, cAMP, MAPK, and PKC, which regulate insulin secretion, cell proliferation, and inflammation.
The effectiveness of GLP-1 medications is driven by their ability to activate specific cellular pathways (ERK1/2, AMPK, cAMP, MAPK, PKC). These pathways control insulin release, cell growth, and inflammation, which is why these drugs work for both diabetes and potentially other conditions like cancer or cardiovascular disease.
GoodSupportsHIGH confidence
The secret of GLP-1RAs’ medicinal efficacy is their complex interplay with several cellular signaling pathways... Beta cell insulin production is enhanced by activation of pathways such as ERK1/2 and AMPK... GLP-1 influences a complex network of signaling cascades, and recent investigations have shown that the MAPK and PKC pathways are also involved.
Why this rating
The paper reviews multiple studies linking these pathways to GLP-1 effects.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
