The changes of Chromatin Accessibiliy Triggered by Unilateral Nephrectomy [ATAC-seq]

ABSTRACT: Purpose: Experiments were done in mice undergoing unilateral nephrectomy (UNx) and sham nephrectomy. At specific time points (24 hours and 72 hours) after surgery, the earliest first portion of the kidney proximal tubule (PT-S1) and the cortical collecting duct (CCD) were manually micro-dissected and utilized for transcriptomic analysis by single-tubule small sample RNA-Seq and single-tubule ATAC seq. Methods: We carried out ATAC-sequencing in microdissected ealiest portion of proximal tubules (PT-S1) from mice with or without (sham) unilateral nephrectomy (UNx). Each group (Sham or UNx) has 3 biological replicates. Results and conclusion: ATAC-seq peaks in microdissected PT-S1 revealed a predominance of binding site motifs corresponding to PPARα.

Transcriptome Changes of Microdissected Kidney Tubules triggered by Unilateral Nephrectomy [RNA-seq]

Project description:Purpose: Experiments were done in mice undergoing unilateral nephrectomy (UNx) and sham nephrectomy. At specific time points (24 hours and 72 hours) after surgery, the earliest first portion of the kidney proximal tubule (PT-S1) and the cortical collecting duct (CCD) were manually micro-dissected and utilized for transcriptomic analysis by single-tubule small sample RNA-Seq. Methods: We carried out RNA-sequencing in microdissected ealiest portion of proximal tubules (PT-S1) or cortical collecting duct (CCD) from mice with or without (sham) unilateral nephrectomy (UNx). Each group (Sham or UNx) has 3-5 biological replicates. Results and conclusion: RNA-Seq in microdissected PT-S1 at 24 hours showed that peroxisome proliferator-activated receptor alpha (PPARα) target genes were strongly upregulated. RNA-Seq in microdissected PT-S1 at 72 hours showed that cell cycle related genes were strongly upregulated. RNA-Seq in microdissected CCD at both 24 hours and 72 hours showed that cell cycle related genes were strongly upregulated.

Early Signaling Events in Renal Compensatory Hypertrophy Revealed by Multi-Omics

Project description:Loss of a kidney results in compensatory growth of the remaining kidney, a phenomenon of considerable clinical importance. However, the mechanisms involved are largely unknown. Here, we used a multi-omic approach in a mouse unilateral nephrectomy model to identify signaling processes associated with compensatory hypertrophy of the renal proximal tubule. Morphometry applied to microdissected proximal tubules showed that growth of the proximal tubule involves a marked, rapid increase in cell volume rather than cell number. Measurements of DNA accessibility (ATAC-seq), transcriptome (RNA-seq) and proteome (quantitative protein mass spectrometry) independently identified patterns of change that are indicative of activation of the lipid-regulated transcription factor, PPARα. Activation of PPARα by fenofibrate administration increased proximal tubule cell size, while genetic deletion of PPARα in mice decreased it. The results indicate that PPARα is an important determinant of proximal tubule cell size and is a likely mediator of compensatory proximal tubule hypertrophy.

The transcriptional response to unilateral nephrectomy with and without ischemia-reperfusion injury

Project description:Transcriptome analysis was done after warm renal ischemia-reperfusion injury (IRI) in a rat model. Earlier studies have shown a protective effect of prior unilateral nephrectomy (UNx) against IRI in the remaining, contralateral kidney compared to a non-neprectomized control group. We aimed at identifying the underlying molecular mechanisms. We used the Affymetrix Clariom D array (formerly known as RTA 1.0 st.) Array data was processed in the Affymetrix Console Software.

Immune-mediated Tubule Atrophy Promotes Acute Kidney Injury to Chronic Kidney Disease Transition

Project description:Incomplete repair after acute kidney injury (AKI) is associated with progressive loss of tubular cell function and development of chronic kidney disease (CKD). Here, we compared the kidney single-cell transcriptomes from the mice subjected to either unilateral ischemia-reperfusion kidney injury with contralateral nephrectomy (IRI/CL-NX, in which tubule repair predominates) or unilateral IRI with contralateral kidney intact (U-IRI, in which fibrosis and atrophy predominates) to investigate the mechanism(s) underlying transition to CKD following AKI.

Circadian Gene Expression in Mouse Renal Proximal Tubule

Project description:Circadian variability in kidney function has long been recognized but is often ignored as a potential confounding variable in in vivo physiological experiments. To provide a guide for physiological studies on the kidney proximal tubule, we have now created a data resource consisting of expression levels for all measurable mRNA transcripts in microdissected proximal tubule segments from mice as a function of the time of day. This approach employs small-sample RNA-sequencing (RNA-seq) applied to microdissected renal proximal tubules including both S1 proximal convoluted tubules (PCTs) and S2 proximal straight tubules (PSTs). The data were analyzed using JTK-Cycle to detect periodicity. The data are provided as a user-friendly web page at https://esbl.nhlbi.nih.gov/Databases/Circadian-Prox/. In PCTs, 234 transcripts were found to vary in a circadian manner (3.7 % of total quantified). In PSTs, 334 transcripts were found to vary in a circadian manner (5.3 % of total quantified). Transcripts previously known to be associated with corticosteroid action and transcripts associated with increased flow were found to be overrepresented among circadian transcripts peaking during the “dark” portion of the day (Zeitgeber 14-22), corresponding to the peak levels of corticosterone and glomerular filtration rate in mice.

miRNome changes in the mouse kidney after unilateral ischemia-reperfusion injury and delayed contralateral nephrectomy

Project description:Comparing the effect of unilateral ischemia-reperfusion injury (IRI) or sham operation (sIRI) with delayed contralateral nephrectomy (Nx) or sham operation (sNx) in mouse kidney. IRI was performed on day 0 and the contralateral kidney was removed on day 7. Mice were sacrificed on day 8. Four animals were selected from the sham IRI-sham Nx and sham IRI-Nx groups and six animals were selected from the IRI-sham Nx and IRI-Nx groups for miRNA microArray analysis on the base of their proinflammatory (TNF-α and IL-6 and CCL2) and immune system-related (Complement component 3) mRNA expression levels.

Expression data from uninephrectomized dogs compared to sham operated dogs

Project description:Renal insufficiency is a risk factor for development of cardiovascular disease. In this study our aim was to investigate functional and structural changes in the heart of dogs with mild renal insufficiency induced by uninephrectomy (UNX). In addition to comprehensively assessing functional parameters 12 week after UNX or sham surgery, we harvested tissue for assessment of structural changes. Microarray analyses were performed on snap frosen tissue from the left atrium (LA) and left ventricle (LV) of UNX and sham operated animals. Gene expression in LA was compared between the groups, and gene expression in the LV was compared between the groups. We aimed to assess whether a potentially altered gene expression in the heart of the UNX group also included genes associated with cardiac remodeling. Six dogs were assigned to unineprectomy and 6 dogs were assigned to sham operation. Microarray analyses were performed on 5 samples from the left atrium of uninephrectomized animals and on 5 samples from the left atrium of sham operated animals. Further, microarray analyses were performed on 5 samples from the left ventricle of uninephcretomized animals and on 5 samples from the left ventricle of sham operated animals. No replicates were perfomed.
