Negative feedback regulation within NO/cGMP pathway attenuates vasodilatory response in renovascular hypertension

Background Hypertension, the leading risk factor for cardiovascular mortality has been associated with alterations in endotheliumand smooth muscle-dependent vascular relaxation. The NO/cGMP signaling cascade is one of the major pathways that mediate vascular relaxation. In this pathway, the NO receptor guanylyl cyclase (NO-GC) holds a key position by converting the NO signal into cGMP increases...

Phosphodiesterase 5 Attenuates the Vasodilatory Response in Renovascular Hypertension

NO/cGMP signaling plays an important role in vascular relaxation and regulation of blood pressure. The key enzyme in the cascade, the NO-stimulated cGMP-forming guanylyl cyclase exists in two enzymatically indistinguishable isoforms (NO-GC1, NO-GC2) with NO-GC1 being the major NO-GC in the vasculature. Here, we studied the NO/cGMP pathway in renal resistance arteries of NO-GC1 KO mice and its r...

Exercise training attenuates renovascular hypertension partly via RAS- ROS- glutamate pathway in the hypothalamic paraventricular nucleus

Exercise training (ExT) has been reported to benefit hypertension; however, the exact mechanisms involved are unclear. We hypothesized that ExT attenuates hypertension, in part, through the renin-angiotensin system (RAS), reactive oxygen species (ROS), and glutamate in the paraventricular nucleus (PVN). Two-kidney, one-clip (2K1C) renovascular hypertensive rats were assigned to sedentary (Sed) ...

Renovascular Hypertension

The effect of hypertension and of therapy by converting enzyme inhibitor (S 9490-3, perindopril) on the function and structure of large arteries has been studied in two-kidney, one-clip Gddblatt hypertensive rats. After one month without treatment, clipped hypertensive rats (n = 24) and sham-operated rats (n = 24) were randomly allocated to treatment by S 9490,1 mg/kg once a day (n = 24) or to ...

Intracardiac Thrombus in Renovascular Hypertension: A Case Report

Thromboembolism is a rare complication of primary nephortic syndrome. Both venous and arterial thrombosis might occur in steroid responsive and steroid resistant nephrotic syndrome. This is the report of an infant with nephrotic syndrome and renovascular hypertension, complicated with asymptomatic intracardiac thrombus and managed appropriately with medical treatment.
