Effects of water restriction on gene expression in mouse renal medulla

ABSTRACT: 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.

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-h water restriction protocol. In this study, 4,625 genes of the possible approximately 12,000 genes on the array were included in the analysis, and of these 157 transcripts were increased and 63 transcripts were decreased by 1.5-fold or more. Quantitative, real-time PCR measurements confirmed the increases seen for 12 selected tr ...[more]

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

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).

Aquaporin-1 Knockout vs Wild type Mice (Re-spot found)

Project description:This dataset was derived (re-spot found) from the original images used in GSE1298. This experiment compared aRNA derived from the kidney inner medula of three mice lacking a functional aquaporin-1 gene to three wild type mice. Each sample was hybridized 4 times, against 4 of the other 5 samples, using an interwoven loop experimental design. Keywords: repeat sample

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.

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.

Genetic deletion of Pax2 and Pax8 in adult mice

Project description:Background: The mammalian kidneys maintain salt and water homeostasis for proper electrolyte balance and hydration. As the glomerular filtrate passes through the nephron and into the renal medulla, electrolytes, water, and urea are reabsorbed through the concerted actions of solute carrier channels and aquaporins located at various positions along the nephron and in the outer and inner medulla. Renal epithelial cells develop from Pax2 positive proliferating stem cells that suppress Pax2 expression once differentiated into mature proximal and distal tubules, but continue to express the related Pax8 protein. The collecting tubules and renal medulla are derived from a Pax2 positive ureteric bud epithelia that continue to express Pax2 and Pax8 in adult kidneys. Despite the necessity for Pax2 in renal development, functions for Pax2 or Pax8 in adult renal epithelia have not been established. Methods: In this report, we deleted either Pax2, Pax8, or both genes in adult mice and examined the phenotypes and changes in gene expression patterns. The mechanism of Pax8 mediated activation of potential target genes was described in inner medullary collecting duct cells. Results: Mice with induced deletions of both Pax2 and Pax8 exhibit severe polyuria that can be attributed to significant changes in the expression of solute carriers, such as the urea transporter UTA1, and aquaporins within the inner and outer medulla. Furthermore, Pax8 expression is induced by high salt in collecting duct cells and activates the UTA1 gene by recruiting a histone methyltransferase complex to the promoter. Conclusions: These data uncover novel functions for Pax proteins, in adult renal epithelia, that are essential for retaining water and concentrating urine.

Neutral amino acid transporter SNAT2 protects renal medulla from hypertonicity-induced ferroptosis

Project description:Hypertonicity in renal medulla is essential for urine concentration and water homeostasis. However, how renal medullary collecting duct cells (MCDs) survive and function under the harsh hypertonic stress remains incompletely understood. By using the RNA-seq technique, we identified SNAT2 (slc38a2) as a novel osmoresponsive neutral amino acid transporter in MCD cells. We found that hypertonic stress induced cell death of MCDs mainly via ferroptosis.
