Project description:We investigated morphometric structure and gene expression by microarray analysis in a small diameter artery, branch of the saphenous artery (a resistance artery), in representative models of renin-angiotensin system (RAS)-dependent and glucocorticoid hypertension, using the spontaneously hypertensive rat (SHR) and adrenocorticotropic hormone (ACTH)-induced hypertensive rat, respectively. Sixteen-week-old male Wistar-Kyoto (WKY) and age-matched spontaneously hypertensive rats (SHR) were used. Keywords: Comparison of global gene expression in resistance arteries of normotensive and genetically hypertensive rats and ACTH-treated rats.
Project description:We aimed to identify gene variants associated with heart failure by using a rat model of the human disease. We performed invasive cardiac hemodynamic measurements in F2 crosses between spontaneously hypertensive heart failure rats (SHHF) and reference strains. We combined linkage analyses with genome-wide expression profiling .
Project description:Hypertension remains a poorly understood condition, and the understanding of the sympathetic nervous systems role in this disease remains even more limited. In this study, RNA-sequencing is used to identify transcriptomal differences in the sympathetic stellate ganglia between the 16-week-old normotensive wistar strain and the spontaneously hypertensive rat strain.This dataset should allow for further molecular characterisation of hypertensive changes in a cardiac-innervating sympathetic ganglion.
Project description:Spontaneously hypertensive rat (SHR; Rat Genome Database (RGD) ID: 631848) is probably the most commonly used rodent model for essential hypertension. Its minimal congenic subline PD5 ( SHR.PD-(D8Rat42-D8Arb23)/Cub; (RGD ID: 1641851)) which differs by a short segment of chromosome 8 (encompassing only 7 genes) displays lower levels of blood pressure and amelioration of cardiac fibrosis compared to SHR. We used microarray aproach to unravel gene expression differences between SHR and PD5 responsible for the different phenotypes in our rat strains.
Project description:Inflammation and oxidative stress have been implicated in the pathogenesis of metabolic disturbances. Esters of fumaric acid, mainly dimethyl fumarate (DMF), exhibit immunomodulatory, anti-inflammatory, and anti-oxidative effects. In the current study, we tested the hypothesis that fumaric acid ester treatment of an animal model of inflammation and metabolic syndrome, the spontaneously hypertensive rat transgenically expressing human C-reactive protein (SHR-CRP), will ameliorate inflammation, oxidative stress, and metabolic disturbances.
Project description:We established a new minimal congenic rat strain containing only a single gene, Zbtb16, from a metabolic syndrome model, the polydactylous rat (PD/Cub) strain, within the spontaneously hypertensive rat (SHR) strain genomic background. 16-week-old SHR and SHR-Zbtb16 rat dams were fed either standard diet during pregnancy and 4 weeks of lactation (control groups) or a high-sucrose diet (HSD, 70% calories as sucrose) during the same period. We have compared the transcriptome profile (GeneChip Rat Gene 2.1 ST Array Strip) in liver, brown and white adipose tissue in adult male offspring of SHR and SHR-Zbtb16 rat dams.
