The cardiovascular and other actions of angiotensin II (Ang II) are mediated by AT(1) and AT(2) receptors, which are seven transmembrane glycoproteins with 30% sequence similarity. Most species express a single autosomal AT(1) gene, but two related AT(1A) and AT(1B) receptor genes are expressed in rodents. AT(1) receptors are predominantly coupled to(More)
BACKGROUND Angiotensin type 1 receptor (AT(1)R) blockers (ARB) have been shown to reduce the incidence of type 2 diabetes mellitus by an unknown molecular mechanism. The peroxisome proliferator-activated receptor-gamma (PPARgamma) is the central regulator of insulin and glucose metabolism improving insulin sensitivity. We investigated the regulation of(More)
Selective peroxisome proliferator-activated receptor (PPAR) gamma modulation is a new pharmacological approach that, based on selective receptor-cofactor interactions and target gene regulation, should result in potent insulin sensitization in the absence of PPARgamma-mediated adverse effects. Here, we characterize two angiotensin receptor blockers (ARBs),(More)
Angiotensin II (ANG II) is known to be a potent growth promoting factor for vascular smooth muscle cells and fibroblasts but little is known about its influence on growth in endothelial cells. We studied the effects of ANG II on endothelial growth and the role of the angiotensin receptor subtypes involved. Proliferation of rat coronary endothelial cells(More)
In the treatment of hypertension, physicians’ attitudes and practice patterns are receiving increased attention as contributors to poor blood pressure (BP) control. Thus, current use of antihypertensive drugs in primary care was analyzed and the association with selected physician and patient characteristics was assessed. The Hypertension and Diabetes Risk(More)
From pharmacological investigations and clinical studies, it is known that ACE inhibitors exhibit additional local actions that are not related to hemodynamic changes and that cannot be explained only by interference with the renin-angiotensin system by means of an inhibition of ANG II formation. Because ACE is identical to kininase II, which inactivates(More)
In inflamed tissue--including skeletal muscle--the concentrations of cytokines and neurotrophins are known to increase. However, nothing is known about a possible contribution of these agents to muscle pain and hyperalgesia. The present study investigated acute effects of cytokines and neurotrophins on response properties of slowly conducting muscle(More)
The cardiocytes of mammalian cardiac atria contain granules very similar to those in endocrine cells. The number of these atrial granules is related directly to salt loading and blood volume. Furthermore, crude extracts of rat atria and granule preparations have powerful natriuretic and diuretic effects. These effects are mediated by peptides identified(More)
BACKGROUND Adipose tissue inflammation may play a critical role in the pathogenesis of insulin resistance (IR). The present study examined the role of lymphocytes in adipose tissue inflammation and IR. METHODS AND RESULTS In a mouse model of obesity-mediated IR, high-fat diet (HFD) induced IR already after 5 weeks, which was associated with a marked(More)
We have previously described a rat model that responds to repetitive episodic hypoxia (FiO2 nadir 3-5% for 12 seconds every 30 seconds for 7 hr/day for 35 days) with chronic increase in arterial blood pressure. The purpose of the current study was to determine if peripheral sympathetic nervous system denervation blocks this persistent blood pressure(More)
