Agonist stimulation of certain G protein-coupled receptors (GPCRs) causes shedding of heparin-binding epidermal growth factor (HB-EGF) through activation of matrix metalloproteinases (MMPs), with subsequent transactivation of the EGF receptor. MMPs are widely expressed, and their dysregulated expression is crucial in cancer, inflammation, and cardiovascular remodeling. Recent studies in hypertensive animals have shown enhanced expression and activation of MMPs and EGF receptors, and their inhibition attenuates cardiac hypertrophy, vasoconstriction and hypertension induced by GPCR agonists such as angiotensin II, endothelin-1 and phenylepherine. These findings suggest that selective inhibition of MMPs might have therapeutic potential in hypertension and other cardiovascular diseases.
