1. In the present study, we investigated the effects of chronic treatment of stroke-prone spontaneously hypertensive rats (SHRSP) with the statin fluvastatin on vascular Rho/Rho-kinase pathway mediated contraction, which has been shown to be upregulated in hypertension. 2. Contribution of the Rho/Rho-kinase pathway to noradrenaline-induced contraction of arteries from SHRSP was assessed by the inhibitory effect of Y-27632, a Rho/Rho-kinase inhibitor. Stroke-prone spontaneously hypertensive rats were treated with fluvastatin (10 mg/kg per day) for 1 month. 3. Treatment with fluvastatin tended to attenuate the contraction to noradrenaline and significantly decreased the Y-27632-sensitive component of the contraction in controls compared with fluvastatin-treated rats. 4. RhoA, as assessed by western blotting, was also reduced by fluvastatin treatment. 5. These findings suggest that chronic treatment with fluvastatin reduces the contractile response associated with Rho/Rho-kinase in arteries of hypertensive rats.
