Transcription profiling of rat heart (Sprague-Dawley) after subtotal nephrectomy (SNX) vs sham (sham) operation at 2 and 12 week timepoints

ABSTRACT: Rats (Sprague-Dawley) were allotted to subtotal nephrectomy (SNX) or sham (sham) operation. After 2 and 12 weeks the experiment was terminated. RNA was isolated from small pieces of the hearts.

Gene expression profile at bulk (24h, 48h & 72h) and single nucleus (24h) level of mouse right kidney post sham operation and unilateral nephrectomy.

Project description:The mechanism driving the remarkable ability of the remaining kidney to enlarge and increase its function following removal of its contralateral pair remains elusive. To explore the pathways driving compensatory renal hypertrophy, comprehensive RNA-seq transcriptional studies in the kidneys of mice undergoing hypertrophy 24, 48 and 72 hours following nephrectomy have been undertaken and compared with mice undergoing sham operations. The results reveal substantial time dependent enhancement of cholesterol biosynthesis pathways, increases in mitochondrial gene expression and cell cycle perturbations. Single nuclei RNA-Seq 24 hours post nephrectomy was used to further explore cholesterol biosynthesis signature and its driver SREBP2. In a cell specific manner, snRNA-seq demonstrated that SREBP2 activity increases in proximal tubules and medullary thick ascending limb and is responsible for cell size regulation following IGF-1 stimulation. These results suggest a previously undescribed role for SREBP2 in the mechanism underlying compensatory renal hypertrophy. This mechanism might be amenable to therapeutic manipulation to enhance kidney size and function.

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

Transcription profiling of mouse lung to investigate effects of ischemia reperfusion injury or nephrectomy

Project description:Experiments in rodents have shown that kidney ischemia/reperfusion injury (IRI) facilitates lung injury and inflammation. To identify potential ischemia-specific lung molecular pathways involved, we conducted global gene expression profiling of lung 6 or 36 hours following 1) bilateral kidney IRI, 2) bilateral nephrectomy (BNx), and 3) sham laparotomy in C57BL/6J mice. Total RNA from whole lung was isolated and hybridized to 430MOEA (22,626 genes) GeneChips (n=3/group). Experiment Overall Design: All procedures were approved by the Johns Hopkins Animal Care and Use Committee, and were consistent with the National Institutes of Health (NIH) Guide for the Care and Use of Laboratory Animals. Male 6-8 week-old mice (C57BL6/J), weighing approximately 25-30 grams were obtained from Jackson Laboratory (Bar Harbor, ME) and housed under pathogen-free conditions according to NIH guidelines at least five days prior to operative procedures. Experiment Overall Design: Animals were placed on a heating blanket and underwent midline laparotomy with isolation of bilateral renal pedicles. For mice assigned to experimental ischemia-reperfusion injury (IRI), a non-traumatic microvascular clamp was applied across both renal pedicles for 60 minutes. After the allotted ischemia time, the clamps were gently removed, the animals administered 1 ml of sterile saline intraperitoneally, and the incision closed in two layers with 4-0 silk suture. The animals were then allowed to recover with free access to food and water. Sham animals underwent the identical procedure without placement of the vascular clamps. The mice assigned to bilateral nephrectomy (BNx) underwent similar procedures except both renal pedicles were ligated with 5-0 silk suture and the kidneys removed. At 6 or 36 hours following the experimental procedure, the mice were euthanized by exsanguination under pentobarbital anesthesia and lung tissues collected for analysis.

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.
