Project description:SMXA-5 mouse shows a high-fat induced fatty liver. The QTL for fatty liver was mapped on mouse chromosome 12, designated as Fl1sa. Iah1 gene is a candidate gene for Fl1sa. Kidney is the highest tissue of Iah1 gene expression in mouse. We compared the kidney's gene expressions between Iah1-WT mouse and Iah1-KO mouse.

Project description:mRNA expression differences between the liver and kidney of an adult male (homo sapien) were investigated using three technical replicates. The purpose of the experiment was to compare array data generated using Affymetrix with measures of expression obtained using RNAseq (a sequencing approach for measuring expression that utilizes Solexa technology). Keywords: kidney, liver
Project description:Hypertension is a progressive condition that predisposes patients to the development of chronic kidney disease (CKD). Previous genetic and animal studies utilizing the Dahl salt-sensitive (SS) rat, a genetic model of progressive hypertension and CKD, identified that Arhgef11 was playing a role in hypertension and CKD in the Dahl SS model. Arhgef11 is a Rho guanine nucleotide exchange factor involved in the regulation of the cytoskeleton, intracellular trafficking, protein-protein interactions, and transcription factor regulation. Temporal evaluation of SS-WT and SS-Arhgef11-/- rats demonstrated that the loss of Arhgef11 attenuated hypertension and improved renal function. Transcriptome and proteomic studies lead to the hypothesis that dysregulation of these pathways in the kidney, particularly the proximal tubule, may alter sodium handling and ultimately lead to hypertension. Current rat studies confirmed previous work between SS-WT and SS-Arhgef11-/- and investigated early (week 4) transcriptional changes using single nuclei RNA sequencing, present before blood pressure differences are observed. Due to only being able to test systemic loss of Arhgef11 in the rat model, a global knockout (Arhgef11-/-(CMV)), as well as a proximal tubule-specific deletion (Arhgef11-/-(Sglt2)) were studied in the mouse. Studies utilized two models of experimental hypertension: Angiotensin II and deoxycorticosterone acetate (DOCA) + salt. Both models demonstrated a slight protective effect on blood pressure and kidney injury for DOCA experimental models, replicating the rat knockout data. However, the impact of the loss of Arhgef11 was dependent on the type of induced hypertension, with the large effect in the rat model likely explained by the highly permissive genetic background of the Dahl SS model.
Project description:This dataset consists of liver and kidney gene expression profiles of young UM-HET3 mice subjected to the following compounds for 1 month: AS-703026 (liver and kidney), enzastaurin (liver and kidney), GDC-0941 (liver and kidney), ascorbyl-palmitate (kidney), AZD8055 (kidney) and KU0063794 (kidney). Corresponding age-, sex- and strain-matched littermate controls for kidney are also presented. This dataset complements liver RNAseq profiles of control UM-HET3 mice and mice subjected to ascorbyl-palmitate, AZD8055 and KU0063794 (collected and sequenced at the same time) stored at GSE131868.
