Amlodipine and endothelial nitric oxide synthase activity

Tetrahydrobiopterin and endothelial nitric oxide synthase activity.

Association of endothelial nitric oxide synthase gene G894T polymorphism with type two diabetes and diabetic nephropathy

Background: Nitric oxide (NO) produced by endothelial NO synthase (eNOS) mediates a large range of processes, and abnormality in the production of NO has been implicated in diabetic complications including diabetic nephropathy (DN). G894T polymorphism in the eNOS gene has been shown to decreased activity the NO levels of plasma. The association between eNOS Glu298Asp gene polymorphism and DN ri...

Nitric oxide produced by endothelial nitric oxide synthase promotes diuresis.

Extracellular fluid volume is highly regulated, at least in part, by peripheral resistance and renal function. Nitric oxide (NO) produced by NO synthase type 3 (NOS 3) in the nonrenal vasculature may promote fluid retention by reducing systemic vascular resistance and arterial pressure. In contrast, NO produced by renal NOS 3 promotes water excretion by reducing renal vascular resistance, incre...

Tetrahydrobiopterin and endothelial nitric oxide synthase uncoupling.

Tetrahydrobiopterin and Endothelial Nitric Oxide Synthase Uncoupling To the Editor: Gao et al1 reported that oral administration of folate, the tetrahydrobiopterin (H4B) precursor, attenuated endothelial NO synthase (eNOS) uncoupling in abdominal aortic aneurysm. The beneficial effects of H4B supplementation in endothelial dysfunction are beyond dispute, but in vivo demonstration of eNOS (un)co...
