Vasopressin (AVP) and the V2R specific agonist dDAVP 7 day infusion into Aquaporin 1 knockout animals

ABSTRACT: 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).

Effects of water restriction on gene expression in mouse renal medulla

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.

Expression data from mouse collecting duct cell, mpkCCD, in response to a peptide hormone vasopressin analog, dDAVP

Project description:Vasopressin is the major hormone that regulates renal water excretion. It does so by binding to a receptor in renal collecting duct cells, triggering signaling pathways that ultimately regulate the abundance, location, and activity of the water channel protein aquaporin 2. We took an advantage of quantitative large scale proteomic technologies and oligonucleotide microarrays to quantify steady state changes in protein and transcript abundances in response to vasopressin in a collecting duct cell line, mpkCCD clone 11 (Yu et al. PNAS 2009, 106:2441-2446). This cell line originally developed by Alan Vandewalle’s group recapitulates vasopressin-mediated AQP2 expression and phosphorylation as seen in native colleting duct cells. The mpkCCD cells were grown on membrane supports to permit polarization. Once transepithelial resistance reached 5kohm per centimeter square and higher, the cells were exposed to the vasopressin V2 receptor analog, dDAVP, at a physiological concentration, 0.1nM, for 5 days. Control experiments were done with cells exposed to vehicle alone. Total RNA was harvested and processed for transcript expression analysis using Affymetrix GeneChip Mouse Genome 430 2.0 Arrays. Each experimental treatment, vehicle and dDAVP, was repeated 3 times.

Effect of dDAVP on outer medullary gene expression in Brattleboro rats

Project description:Activation of the renal urine concentrating mechanism by vasopressin requires the coordinated regulation of multiple gene products including ion transporters, and water channels as well as regulatory proteins like protein kinases and phosphatases or enzymes involved in the energy-metabolism of the cells. We used microarray analysis of AVP-regulated gene products in a rat model of central diabetes insipidus (DI) to generate a comprehensive database documenting these changes. For microarray studies young (8 weeks) adult male Brattleboro rats were randomly divided into 2 groups (n = 3 per group) and treated for 3 days with either 1-desamino-8-D-Arg vasopressin (dDAVP; 5ng/h; Sigma Aldrich, Germany) or vehicle via osmotic minipump (ALZET minipump model 2001, Charles River, Sulzfeld, Germany). At the end of the treatment period animals were sacrificed and the kidneys removed. The outer medulla was isolated and used for cDNA generation and subsequent microarray analysis using [Rat230_2] Affymetrix Rat Genome 230 2.0 Array.

Control and Congestive Heart Failure

Project description:Congestive heart failure was done by artificial myocardial infarction. After extracting total RNA from control and infarcted ventricles with Triazol, messenger RNA was isolated with Qiagen mRNA isolation kit. About 1.5ug poly A+ RNA was taken for probe preparation. Probe was labeled with Alexa Fluor 546 and 657. Labeled probes were hybridized with Qiagen rat unigene oligo library. After 2 low and 1 high stringency washes Prolong Antifade was added to the slides to prevent bleaching effect. The data ratio was normalized using a location and intensity dependent Lowess formula.

Heart Failure, DITPA and Captopril

Project description:Three weeks after infarction, age matched rats with large infarction by ECG criteria were randomly assigned to one of the three groups: 1) Treatment with Captopril for 21 days and a daily subcutaneous dose of DITPA for the last 10 days of treatment, 2) Treatment for 10 days with DITPA alone, 3) Control heart failure and 4) Sham-operated. Keywords: Drug Effects on Heart Failure Total RNA was prepared from left ventricle using TRIzol and later Poly A+ RNA was isolated with Oligotex beads. About 0.5ug Poly A+ RNA was reverse transcribed and labeled with Alexa Fluor 546 and 647. Labeled probed were hybridized with Operon's rat Unigene oligo library printed on glass slides. After 2 lows and 1 high stringency washes, Prolong Antifade was added to the slides to prevent any bleaching effect. The experiments were repeated 2-4 times by dye-swaping. Slides were scanned in Array Worx scanner with dual wave length. The data ratio was normalized using a location and intensity dependent Lowess formula.

Changes of mRNA expressin in rat kidney inner medulla in response to dDAVP stimulation/ withdrawal

Project description:The E3 ubiquitin -protein ligases (E3s) plays a role as regulators of protein trafficking and degradation. We aimed to identify E3s in rat kidney which are associated with dDAVP-induced urine concentration. Kidney inner medulla collected from vehicle treated control (n=2), dDAVP infusion for 5 d (D5d, n=2) and 3 h-withdrawal of dDAVP after 5 d-infusion (D5d-3h, n=2) groups were subjected to a transcriptome analysis.

Transcriptome changes in response to dDAVP stimulation in CRISPR/Cas9 mediated Camk2d knock-out mpkCCD cells

Project description:The Ca2+/CaM-dependent protein kinase 2-delta (CAMK2D) has been proposed to be involved in vasopressin signaling in the renal collecting duct, which controls water and salt excretion by the kidney. RNA sequancing and quantitative proteomics analyses identified the expression of multiple CAMK2 isoforms, with CAMK2D being the most abundant in collecting duct cells. To investigate the role of CAMK2D in regulating RNA expression in response to vasopressin signaling, the transcriptome of CRISPR/Cas9-mediated Camk2d knock-out mpkCCD cells was profiled using RNA-Seq in the presence of vasopressin analogue dDAVP.
