What this claim means

Endothelin-1 reduces the ability of insulin to promote glucose uptake into cells by interfering with the cytoskeletal changes that move GLUT4 transporters to the cell surface.

See the technical phrasing

Endothelin-1 inhibits insulin-stimulated glucose uptake by disrupting RAC1-mediated cytoskeletal remodeling required for GLUT4 translocation.

Why this might work
Verified
based on 5 studies

Endothelin-1 binds to receptors on the cell surface, triggering a signal that breaks down the internal scaffold made of actin and membrane lipids needed to move glucose transporters to the surface. Without this scaffold, the transporters cannot reach the membrane, so glucose cannot enter the cell even when insulin is present.
