Protocatechuic acid activates key components of insulin signaling pathway mimicking insulin activity

Abstract

This study showed that PCA stimulates the insulin signaling pathway in human adipocytes increasing GLUT4 translocation and glucose uptake. Decreasing insulin resistance is a most desirable aim to be reached for an effective therapeutic/preventive action against metabolic syndrome and type 2 diabetes. Identifying specific food/food components able to improve glucose metabolism can offer an attractive, novel, and economical strategy.
