Project description:The results of this study identified a number of pathways potentially important for the amelioration of hypertension and renal injury in SS-13BN/Mcw rats, and these results generated a series of testable hypotheses related to the role of the renal medulla in the complex mechanism of salt-sensitive hypertension. Keywords: time course, microarray; 11ß-hydroxysteroid dehydrogenase; glucagon receptor; extracellular matrix; apoptosis

Project description:Using poly(A)-independent and strand-specific RNA-seq, we identified approximately 1,500 to 1,800 lncRNAs expressed in each of the following tissues of Brown Norway rats: the renal cortex, renal outer medulla, liver, cardiac left ventricle, adrenal gland, and hypothalamus.

Project description:Vasopressin, the antidiuretic hormone, acts on the renal collecting duct. In this experiment both vasopressin (AVP) and the V2R specific agonist dDAVP were infused into Aquaporin 1 knockout animals for 7 days. The aim of the experiment was to identify genes increased by vasopressin receptors in the renal medullary collecting ducts, in the absence of an increase in renal medullary osmolarity (the AQP1 knockouts are concentrating mechanism knockouts). All experiments used inner medulla tissue for the RNA isolation. Hybridizations were performed that compared kidney inner medulla total RNA from three control mice against kidney medulla total RNA from 3 mice infused with either arginine vasopressin (AVP) or des-amino-D-arginine vasopressin (dDAVP).

Project description:Substitution of chromosome 13 from Brown Norway BN/SsNHsd/Mcw (BN/Mcw) rats into the Dahl salt-sensitive SS/JrHsd/Mcw (SS/Mcw) rats resulted in substantial reduction of blood pressure salt sensitivity in this consomic rat strain designated SSBN13. In the present study, we attempted to identify genes associated with salt-sensitive hypertension by utilizing a custom, known-gene cDNA microarray to compare the mRNA expression profiles in the renal medulla (a tissue playing a pivotal role in long-term blood pressure regulation) of SS/Mcw and SSBN13 rats on either low-salt (0.4% NaCl) or high-salt (4% NaCl, 2 wk) diets.

Project description:The results of this study identified a number of pathways potentially important for the amelioration of hypertension and renal injury in SS-13BN/Mcw rats, and these results generated a series of testable hypotheses related to the role of the renal medulla in the complex mechanism of salt-sensitive hypertension. Rats were paired for microarray hybridization, and the results were analyzed. Each of the four between-group comparisons comprised three pairs of rats examined by six microarrays with dye switching for each pair. Dye switching was not necessary for within-group comparisons, because the two rats of each pair were equivalent in terms of their treatment status. The expression data from the present study were combined with those from 24 microarrays hybridized in our previous study and used to identify genes exhibiting the most distinct temporal patterns of expression between SS and SS-13BN/Mcw over the time course studied.

Project description:Numerous adult diseases involving tissues that consist primarily of non-dividing cells are associated with changes in DNA methylation. It suggests a role for de novo methylation or demethylation of DNA, which is catalyzed by DNA methyltransferase 3 (Dnmt3) and ten-eleven translocases (Tet). However, the contribution of DNA de novo (de)methylation to these diseases remains nearly completely unproven. Broad changes in DNA methylation occurred within days in the renal outer medulla of Dahl SS rats fed a high-salt diet, a classic model of hypertension. Intra-renal administration of anti-Dnmt3a/Tet3 GapmeR’s attenuated high salt-induced hypertension in SS rats. The high salt diet induced differential expression of 1,712 genes in the renal outer medulla. Remarkably, the differential expression of 76% of these genes were prevented by anti-Dnmt3a/Tet3 GapmeR’s. The genes differentially expressed in response to the GapmeR’s were involved in the regulation of metabolism and inflammation and were significantly enriched for genes showing differential methylation in response to the GapmeR’s. These data indicate DNA de novo (de)methylation in the kidney contributes to the development of hypertension in SS rats. The findings should help to shift the paradigm of DNA methylation research in diseases involving non-dividing cells from correlative analysis to functional and mechanistic studies.

Project description:In order to identify novel gene targets of vasopressin regulation in the renal medulla, we performed a cDNA microarray study on the inner medullary tissue of mice following a 48 hour water restriction protocol. Three renal medulla of 3 water restricted (WR) mice and three control mice (C) were hybridized against each other such that each WR sample was hybridized against each C sample.
