Project description:The aim of this study is to establish a comprehensive transcriptome atlas that enables identification of key molecular pathways and morphogenic events regulating postnatal renal medulla/papillary and cortex development. To achieve this, a microarray expression profiling was performed on postnatal day 0-90 renal medulla and cortex obtained from CD1 male mice.
Project description:The aim of this study is to establish a comprehensive transcriptome atlas that enables identification of key molecular pathways and morphogenic events regulating postnatal renal medulla/papillary and cortex development. To achieve this, a microarray expression profiling was performed on postnatal day 0-90 renal medulla and cortex obtained from CD1 male mice. Renal medulla and cortex were regionally dissected from postnatal day 0-90 CD1 male mice, and total RNA extracted for microarray expression profiling. Each time point consists of RNA pooled from 4 biological replicates, and an Agilent Bioanalyser test was performed to assess RNA integrity prior to sample pooling. The microarray data was analysed with the use of lumi and limma packages (Bioconductor) in R.
Project description:This SuperSeries is composed of the following subset Series: GSE28283: Renal cortex microRNA expression differences between hypertensive and normotensive patients GSE28344: Renal medulla microRNA expression differences between hypertensive and normotensive patients GSE28345: Renal cortex expression differences between hypertensive and normotensive patients GSE28360: Renal medulla expression differences between hypertensive and normotensive patients Refer to individual Series
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:To determine the changes in intra-renal gene expression in a novel large animal model of post Cardiopulmonary Bypass (CPB) acute kidney injury, we collected renal medulla samples obtained 24hours post intervention. The transcriptional profile of the mRNA in these samples was measured with gene array technology. Pigs were subjected to 2.5 hours of general anaesthesia or 2.5 hours of CPB under general anaesthesia. Renal medulla samples were collected 24 hours post intervention.
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:Identification of renal medulla microRNAs whose expression differs between male individuals with high blood pressure and normal blood pressure using Agilent Human miRNA Microarrays (V3, release 12.0).
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.
Project description:Comparison between renal papilla tissue with and without the presence of calcified Randall’s plaques, and between the papilla, medulla, and cortex regions from within a single recurrent stone forming kidney demonstrated that patterns of gene expression between the papilla, medulla, and cortex that distinguished these three regions from one another. Disease and function analysis of these gene sets demonstrated up-regulation of genes related to urinary/renal disorders, granulocyte response, vascular smooth muscle cell proliferation, dehydration, and renal calcification and down-regulation of genes related to carboxylic acid/ lipid/ fatty acid transport and urine osmolality.
