Previous studies have demonstrated that angiotensin II (Ang II) is involved in the process of atherosclerosis and vascular restenosis through its proinflammatory effect.
The purpose of this study was to define the role of MasR deficiency in AngII-induced atherosclerosis and AAA formation and severity in hypercholesterolemic male mice.
This study was designed to investigate the effect of the angiotensin II receptor blocker olmesartan alone, or in combination with standard treatment with a statin, pravastatin, on atherosclerosis development in APOE*3Leiden transgenic mice.
Angiotensin II (ANG II) type 1 (AT1)-receptor blockade reduces LDL-modification and atherosclerotic plaque formation in rodent and primate models of atherosclerosis.
While adoptive transfer of B cells in Apoe <sup>-/-</sup> /Baffr <sup>-/-</sup> mice reversed atheroprotection in the absence of AngII, infusion of AngII in B cell replenished Apoe <sup>-/-</sup> /Baffr <sup>-/-</sup> mice unexpectedly prevented the progression of atherosclerosis.
During active disease, patients with granulomatosis with polyangiitis (GPA; Wegener's granulomatosis) have accelerated atherosclerosis and ANGII inhibitors are recommended to these patients to reduce atherosclerosis.
It is assumed that the excess supply of angiotensin II (due to the deletion polymorphism of the angiotensin-converting enzyme gene) contributes to endothelial dysfunction and in this way promotes the onset and progression of atherosclerosis.
These results suggest AGT genetic variants as a risk factor for chronic heart failure compared to advanced atherosclerosis disease without heart failure, with a strong difference between IHD patients and chronic heart failure patients with ischemic heart disease, especially in haplotypes and associated genotypes.
Two of the 9 SNPs, rs2106261 (16q22) and rs6666258 (1q21), revealed interaction relationships that neared statistical significance (with point estimates in the same direction for angiotensin-converting enzyme inhibitor only and angiotensin II receptor blocker only analyses), but neither association could be replicated among 8,604 participants in Atherosclerosis Risk in Communities.
Additionally, lncRNAs have been associated with angiotensin II actions and with vascular diseases, including coronary heart disease and atherosclerosis. miRNAs, well studied in various vascular diseases, have also been recently shown to be differentially expressed in the biofluids of patients with vascular disease and mediate cell-cell communication.
Mice deficient both in ApoE and in kinin B1 receptor (ApoE(-/-)-B(1)(-/-)) were generated and analyzed for their susceptibility to atherosclerosis and aneurysm development under cholesterol rich-diet (western diet) and angiotensin II infusion.
This is a model of hypertension and atherosclerosis because of high angiotensin II and aldosterone levels as a result of the transgenic expression of the entire human renin-angiotensin system.
The effects of angiotensin II, which may be at least partially genetically mediated, have been implicated in epidemiologic and clinical studies as a risk factor for the development of atherosclerosis.
Its effects on ROS production, AP-1 activity, plasminogen activator inhibitor 1 (PAI-1) gene expression, and cellular proliferation and migration were measured in response to high glucose and angiotensin II (Ang II) concentrations, two major factors in the pathogenesis of atherosclerosis in patients with diabetes and hypertension.
Angiotensin II type 1 receptor antagonists (AIIA) are beneficial for the prevention of atherosclerosis and diabetic nephropathy suggesting that angiotensin II (Ang II) promotes the development of these diseases.
A missense gene mutation with methione-to-threonine amino acid substitution at codon 235 (M235T) of angiotensinogen (AGT) has been associated with higher plasma AGT levels and may influence the pathogenesis of cardiac hypertrophy and atherosclerosis.
