Siragy HM, Inagami T, Carey RM. NO and cGMP mediate angiotensin AT2 receptor-induced renal renin inhibition in young rats. Am J Physiol Regul Integr Comp Physiol 293: R1461–R1467, 2007. First published August 1, 2007; doi:10.1152/ajpregu.00014.2007.—We hypothesized that angiotensin subtype-2 receptor (AT2R) inhibits renal renin biosynthesis in young rats via nitric oxide (NO). We monitored chan...
Adaptive growth responses of the embryo and fetus to nutritional restraint are important in ensuring early survival, but they are implicated in the programming of hypertension. It has been demonstrated that kidney growth and nephrogenesis are each regulated by intrarenal factors, including the insulin-like growth factors, glucocorticoids, and the renin-angiotensin system. Therefore, we have inv...
BACKGROUND We demonstrated earlier that angiotensin II (Ang II), by AT(1) receptor activation, upregulates oxidized LDL (ox-LDL) endothelial receptor LOX-1 gene expression and uptake of ox-LDL in human coronary artery endothelial cells (HCAECs). In this study, we investigated the regulation of Ang II receptors (AT1R and AT2R) by ox-LDL and the role of the redox-sensitive transcription factor NF...
Clayton SC, Haack KK, Zucker IH. Renal denervation modulates angiotensin receptor expression in the renal cortex of rabbits with chronic heart failure. Am J Physiol Renal Physiol 300: F31–F39, 2011. First published October 20, 2010; doi:10.1152/ajprenal.00088.2010.—Excessive sympathetic drive is a hallmark of chronic heart failure (HF). Disease progression can be correlated with plasma norepine...
Local bone interaction between renin-angiotensin system and kallikrein-kinin system in diabetic rat.
OBJECTIVE This study was performed to investigate bone deteriorations and the involvement of skeletal renin-angiotensin system (RAS) and kallikrein-kinin system (KKS) of male rat in response to the hyperglycemia. METHODS The biomarkers in serum and urine were measured by ELISA kit, and tibias were taken for the measurement on gene, protein expression and histological analysis, femurs were tak...
During high-salt (HS) diet the kidney increases urinary Na+ and volume excretion to match intake. We recently reported that HS provokes a redistribution of distal convoluted tubule Na+-Cl- cotransporter (NCC) from apical to subapical vesicles and decreases NCC abundance. This study aimed to test the hypothesis that the other renal Na+ transporters' abundance and or subcellular distribution is d...
The adipose-specific protein adiponectin has been recently discovered to improve insulin sensitivity. Angiotensin type-1 receptor (AT1R) blockers (ARBs) reduce the incidence of type 2 diabetes mellitus by mostly unknown molecular mechanisms. To identify new antidiabetic mechanisms of ARBs, we studied the regulation of adiponectin by angiotensin II (Ang II) and different ARBs in murine 3T3-L1 ad...
Functional modulation of the non-AT1R arm of the renin-angiotensin system, such as via AT2R activation, is known to improve stroke outcome. However, the relevance of the Mas receptor, which along with the AT2R forms the protective arm of the renin-angiotensin system, as a target in stroke is unclear. Here we tested the efficacy of a selective MasR agonist, AVE0991, in in vitro and in vivo model...
Objective(s): Considering the lack of information, the effects of mild endurance exercise plus blood flow restriction (BFR) on electrocardiographic parameters, hypertrophy index, and expression of angiotensin II receptors type 1 (AT1R) and type 2 (AT2R) and apelin receptor (APJ) were assessed in hearts of old male rats.Materials and Methods: Animal were grouped as control (CTL), Sham (Sh), lowe...
Moderately elevated maternal cortisol levels late in gestation cause enlargement of the fetal sheep heart. We have used quantitative real-time PCR to examine expression of candidate genes in fetal hearts from mothers in whom cortisol levels were increased (by infusion of 1 mg cortisol.kg(-1).day(-1)) or decreased (by adrenalectomy and replacement to 0.5 mg cortisol.kg(-1).day(-1)) from 115 to 1...
