Stimulation of receptors causing arterial contraction may also cause attenuation of cell responsiveness to stimuli. This study tested the hypothesis that attenuation of receptor-induced contractions involves Ca2+desensitization. Renal artery rings we

We investigated the role of nicotinic and muscarinic receptors in secretion of catecholamines induced by transmural electrical stimulation (ES) from isolated perfused adrenal glands of spontaneously hypertensive rats (SHRs) and normotensive Wistar-Ky

We determined the contributions of angiotensin II type 1 receptor (AT1) stimulation, adrenergic stimulation, and autonomic activation to pressure overload-induced c- fos expression in the adult rat heart in vivo. c- fos expression was increased in pr

Fibroblast growth factor (FGF-2), a mitogenic, angiogenic, and cardioprotective agent, is reported to be released from the postnatal heart by a mechanism of transient remodeling of the sarcolemma during contraction. This release can be increased with

Stimulation of single Ehrlich ascites tumor cells with agonists (bradykinin, thrombin) and with arachidonic acid (AA) induces increases in the free intracellular Ca2+concentration ([Ca2+]i) in the presence and absence of extracellular Ca2+, measured

Increasing evidence indicates that factors other than adrenocorticoid hormones can influence long-term regulation of Na+transport by inner medullary collecting duct (IMCD) cells. We now report that, of 14 interleukins tested, only interleukin-1α (IL

The present study was performed to characterize thrombin-stimulated phospholipase A2(PLA2) activity and the resultant release of lysophospholipids from endothelial cells. The majority of PLA2activity in endothelial cells was membrane associated, Ca2+

The effects of epinephrine on glucose metabolism during contractile activity and insulin stimulation were investigated in fast-twitch (epitrochlearis) and slow-twitch (soleus) muscles from Wistar rats. All muscles were mounted on contraction apparatu

This study aimed to characterize the cellular pathways along which nitric oxide (NO) influences the secretion of renin from the kidney. Using the isolated perfused rat kidney model, we found that the NO donor sodium nitroprusside (SNP) (1–30 μmol/

To study and define the early time-dependent response (≤6 h) of blocker-sensitive epithelial Na+channels (ENaCs) to stimulation of Na+ transport by aldosterone, we used a new modified method of blocker-induced noise analysis to determine the change
