Transcription profiling of rat Dahl salt-sensitive strain development of proteinuria

Project description:To get more insight in cause and consequences of proteinuria, we studied glomerular gene expression patterns before and after the onset of increased urinary albumin excretion in a proteinuric rat strain. Spontaneously proteinuric Dahl salt-sensitive rats (Dahl SS) were compared to non-proteinuric, spontaneously hypertensive rats (SHR). In Dahl SS, UAE significantly increased starting from week 5 of age. Glomerular RNA profiles of 4- and 6 week-old rats were studied by Affymetrix microarrays. Experiment Overall Design: RNA was extracted from isolated glomeruli of 4- and 6 week-old rats from both strains. At each time point, two rats were used for each strain.

Transcriptomic Analysis in Renal T Lymphocytes Exposes Sodium-Independent Dietary Differences in Dahl Salt-Sensitive Rats

Project description:Background. The Dahl salt-sensitive (SS) rat is an established model of salt-sensitive hypertension and renal damage. Recently, sodium-independent dietary effects were shown to be important in the development of the SS hypertensive phenotype. Compared to Dahl SS/JrHsdMcwi (SS/MCW) rats fed a purified diet (AIN-76A), grain-fed Dahl SS/JrHsdMcwiCrl rats (SS/CRL; Teklad 5L2F) were less susceptible to salt-induced hypertension and renal damage. Methods. With the known role of the immune system in hypertension, the present study characterized the immune cells infiltrating SS/MCW and SS/CRL kidneys. To further identify distinct molecular pathways between SS/MCW and SS/CRL, transcriptomic analysis was performed via RNA sequencing in T-cells isolated from the blood and kidneys of low and high salt-fed rats. Results. Following a 3-week high salt (4.0% NaCl) challenge, SS/CRL rats were protected from salt-induced hypertension (116.5±1.2 vs 141.9±14.4 mmHg) and albuminuria (21.7±3.5 vs 162.9±22.2 mg/day) compared to SS/MCW. Additionally, the absolute number of immune cells infiltrating the kidney was significantly reduced in SS/CRL. RNA-seq revealed >50% of all annotated genes in the entire transcriptome to be significantly differentially expressed in T-cells isolated from blood versus kidney. Pathway analysis of significant differentially expressed genes between SS/MCW and SS/CRL renal and circulating T-cells demonstrated salt-induced changes in genes related to inflammation in SS/MCW compared to metabolism-related pathways in SS/CRL. Conclusions. These functional and transcriptomic T-cell differences between SS/MCW and SS/CRL show that sodium-independent dietary effects may influence the immune response and infiltration of immune cells into the kidney, ultimately impacting susceptibility to salt-induced hypertension and renal damage.

Hypertensive Rat Kidney Study: Gender-Selective Responses to Salt in Dahl-Iwai & Sprague-Dawley Rats

Project description:Dahl-Iwai (DI) salt-sensitive rats were studied using microarrays to identify gender-specific differences in the kidney, both basal differences and responses to a high salt diet. In DI rat kidneys, gene expression profiles demonstrated inflammatory and fibrotic responses selectively in females. Gonadectomy of DI rats abrogated gender differences in gene expression. Gonadectomized female and gonadectomized male DI rats both responded to high salt with the same spectrum of gene expression changes as intact female DI rats. Androgens dominated the gender selective responses to salt. Several androgen-responsive genes were identified with roles potentiating the differential responses to salt including increased male expression of Angiotensin-Vasopressin Receptor and Prolactin Receptor, decreased 5-alpha reductase, and mixed increases and decreases in expression of Cyp4a- genes that can produce eicosanoid hormones. These gender differences potentiate sodium retention by males, and increase kidney function during gestation by females. Keywords: Disease-State Analysis (Salt-Sensitive Hypertension)
