High-Density Lipoprotein Prevents Endothelial Nitric Oxide Synthase Uncoupling in Diabetes Mellitus by Angiotensin II Type 1 Receptor Downregulation
Diabetes mellitus is a major risk factor for cardiovascular disease, and its prevalence is suspected to further increase in the coming years in the Western hemisphere and also in countries with emerging economies, like India, China, and Brazil. Together with the increasing prevalence of obesity and metabolic syndrome and the subsequent development of arterial hypertension, the epidemic of adipo...
متن کاملSphingosine kinase-dependent activation of endothelial nitric oxide synthase by angiotensin II.
OBJECTIVE In addition to their role in programmed cell death, cell survival, and cell growth, sphingolipid metabolites such as ceramide, sphingosine, and sphingosine-1-phosphate have vasoactive properties. Besides their occurrence in blood, they can also be formed locally in the vascular wall itself in response to external stimuli. This study was performed to investigate whether vasoactive comp...
متن کاملAngiotensin-(1-7) through receptor Mas mediates endothelial nitric oxide synthase activation via Akt-dependent pathways.
Angiotensin-(1-7) [Ang-(1-7)] causes endothelial-dependent vasodilation mediated, in part, by NO release. However, the molecular mechanisms involved in endothelial NO synthase (eNOS) activation by Ang-(1-7) remain unknown. Using Chinese hamster ovary cells stably transfected with Mas cDNA (Chinese hamster ovary-Mas), we evaluated the underlying mechanisms related to receptor Mas-mediated posttr...
متن کاملAngiotensin II stimulates synthesis of endothelial nitric oxide synthase.
Previous studies have suggested that NO may play an important role in protecting the renal vessels from angiotensin II (ANGII)-mediated vasoconstriction. One possible mechanism for this interaction is that ANGII could stimulate NO production in the kidney by increasing endothelial NO synthase (NOS III). The present studies were performed in rats to determine whether acute or chronic elevations ...
متن کاملValsartan regulates the interaction of angiotensin II type 1 receptor and endothelial nitric oxide synthase via Src/PI3K/Akt signalling.
AIMS Valsartan, a selective angiotensin II type 1 receptor (AT1R) blocker, has beneficial effects in the cardiovascular system in part by its increase of nitric oxide (NO) bioavailability, yet the mechanisms are unclear. We investigated the molecular mechanisms underlying this effect in endothelial cells (ECs). METHODS AND RESULTS NO production was examined by Griess reagent assay, DAF-2 DA f...
