Inhibition of MMP-9 attenuates hypertensive cerebrovascular dysfunction in Dahl salt-sensitive rats.

ABSTRACT: Hypertensive cerebropathy is a pathological condition associated with cerebral edema and disruption of the blood-brain barrier. However, the molecular pathways leading to this condition remains obscure. We hypothesize that MMP-9 inhibition can help reducing blood pressure and endothelial disruption associated with hypertensive cerebropathy. Dahl salt-sensitive (Dahl/SS) and Lewis rats were fed with high-salt diet for 6 weeks and then treated without and with GM6001 (MMP inhibitor). Treatment of GM6001 (1.2 mg/kg body weight) was administered through intraperitoneal injections on alternate days for 4 weeks. GM6001 non-administered groups were given vehicle (0.9% NaCl in water) treatment as control. Blood pressure was measured by tail-cuff method. The brain tissues were analyzed for oxidativ
