Metalloprotease inhibitor blocks angiotensin II-induced migration through inhibition of epidermal growth factor receptor transactivation

Biochem Biophys Res Commun. 2002 Jun 28;294(5):1023-9. doi: 10.1016/S0006-291X(02)00595-8.

Abstract

In vascular smooth muscle cells (VSMCs), angiotensin II (AngII) induces transactivation of the EGF receptor (EGFR) which involves a metalloprotease that stimulates processing of heparin-binding EGF from its precursor. However, the identity and pharmacological sensitivity of the metalloprotease remain unclear. Here, we screened the effects of several metalloprotease inhibitors on AngII-induced EGFR transactivation in VSMCs. We found that an N-phenylsulfonyl-hydroxamic acid derivative [2R-[(4-biphenylsulfonyl)amino]-N-hydroxy-3-phenylpropinamide] (BiPS), previously known as matrix metalloprotease (MMP)-2/9 inhibitor, markedly inhibited AngII-induced EGFR transactivation, whereas the MMP-2 or -9 inhibition by other MMP inhibitors failed to block the transactivation. BiPS markedly inhibited AngII-induced ERK activation and protein synthesis without affecting AngII-induced intracellular Ca2+ elevation. VSMC migration induced by AngII was also inhibited not only by an EGFR inhibitor but also by BiPS. Thus, BiPS is a specific candidate to block AngII-induced EGFR transactivation and subsequent growth and migration of VSMCs, suggesting its potency to prevent vascular remodeling.
