Renal Dopamine Receptors and Hypertension
Dopamine has been recognized as an important modulator of central as well as peripheral physiologic functions in both humans and animals. Dopamine receptors have been identified in a number of organsExpand

Oxidative stress-induced renal angiotensin AT1 receptor upregulation causes increased stimulation of sodium transporters and hypertension.
Reactive oxygen species have emerged as important molecules in cardiovascular dysfunction such as diabetes and hypertension. Recent work has shown that oxidative stress and angiotensin II signalingExpand

Resveratrol prevents endothelial nitric oxide synthase uncoupling and attenuates development of hypertension in spontaneously hypertensive rats.
Endothelial dysfunction is a hallmark of hypertension and vascular oxidative stress can contribute to endothelial dysfunction and hypertension development. Resveratrol is an antioxidant polyphenolExpand

Angiotensin II AT1 receptor/signaling mechanisms in the biphasic effect of the peptide on proximal tubular Na+,K+-ATPase.
The present study was designed to determine the cellular signaling mechanisms responsible for mediating the effects of angiotensin II on proximal tubular Na+,K+-ATPase activity. Angiotensin IIExpand

Tempol reduces oxidative stress, improves insulin sensitivity, decreases renal dopamine D1 receptor hyperphosphorylation, and restores D1 receptor-G-protein coupling and function in obese Zucker rats.
Oxidative stress plays a pathogenic role in hypertension, particularly the one associated with diabetes and obesity. Here, we test the hypothesis that renal dopamine D1 receptor dysfunction in obeseExpand

Bromocriptine regulates angiotensin II response on sodium pump in proximal tubules.
-Dopamine and angiotensin II (Ang II) receptors have been reported to exhibit an interaction in renal proximal tubules. The present study was designed to investigate the regulation by a D2-likeExpand

Renal dopamine receptor function in hypertension.
Dopamine plays an important role in the regulation of renal sodium excretion. The synthesis of dopamine and the presence of dopamine receptor subtypes (D1A, D1B, as D1-like and D2, and D3 as D2-like)Expand

Oxidative stress causes renal dopamine D1 receptor dysfunction and hypertension via mechanisms that involve nuclear factor-kappaB and protein kinase C.
Renal dopamine, via activation of D1 receptors, plays a role in maintaining sodium homeostasis and BP. There exists a defect in renal D1 receptor function in hypertension, diabetes, and aging,Expand

Vascular oxidative stress upregulates angiotensin II type I receptors via mechanisms involving nuclear factor kappa B
Abstract The association of oxidative stress with hypertension is well known. However, a causal role of oxidative stress in hypertension is unclear. Vascular angiotensin II type 1 receptor (AT1R)Expand

Effect of epinephrine on norepinephrine release from rat kidney during sympathetic nerve stimulation.
Experiments were performed to study presynaptic beta-adrenoceptor facilitation of sympathetic neurotransmitter release in the isolated perfused rat kidney and evaluate the effect of epinephrine onExpand
