Genome-wide chromatin accessibility and gene expression profiling of renal cell carcinoma and matched normal kidney tubules [DNase-seq]

ABSTRACT: We generated primary cultures from renal cell carcinoma and matched normal primary kidney cortex tubule cell cultures from 3 patients. Early passage cultures of these two cell types were subjected to chromatin accessibility profiling (DNase-seq) and gene expression profiling (RNA-seq). Studying these paired and patient-matched controlled data sets will shed light on the epigenomic changes that underlie transformation of kidney tubules into malignant cancers.

Kidney on a Chip

Project description:<p>We generated primary cultures from mechanically isolated kidney glomeruli (filtration unit of the nephron) which are composed of podocytes and mesangial cells. In parallel, we generated primary kidney cortex tubule cell cultures, which are composed primarily of proximal tubule cells. Early passage cultures of these two cell types were subjected to chromatin accessibility profiling (DNase-Seq) and gene expression profiling (RNA-Seq). We found thousands of dynamically regulated enhancers in both cell types that potentially regulate nearby and distal target genes that are differentially expressed. These data will be useful for understanding the epigenomic regulation of gene transcription in key kidney cell types.</p>

Transcription profiling of Drosophila pooled Malpighian tubules vs. whole fly

Project description:This is an affymetrix array experiment comparing the transcriptome of the Malpighian tubule (or renal tubule) of 7-day adult Oregon R strain Drosophila melanogaster with matched whole fly samples. It is described in:,Wang, J., Kean, L., Yang, J., Allan, A. K., Davies, S. A., Herzyk, P. and Dow, J. A. T. (2004). Function-informed transcriptome analysis of Drosophila renal tubule. Genome Biol. In press.,There are five tubule samples (each derived from approx 1000 tubules (!)), and 5 matched whole-fly samples. i.e. tubule 2 is dissected from the same vial as WholeFly2.,As the tubule is probably the premier tissue for true physiology in Drosophila, the dataset can usefully be interrogated in conjunction with the detailed physiological understanding of the tissue: see,http://fly.to/tubules

Transcription profiling of mouse Clcn5 knockout in proximal tubules of the kidney

Project description:Dent disease has multiple defects attributed to proximal tubule malfunction including low molecular weight proteinuria, aminoaciduria, phosphaturia and glycosuria. In order to understand the changes in kidney function of the Clc5 transporter gene knockout mouse model of Dent disease, we examined gene expression profiles from proximal tubules of mouse kidneys. Overall 720 genes are expressed differentially in the proximal tubules of the Dent Clcn5 knockout mouse model compared to those of control wild type mice. The fingerprint of these gene changes may help us to understand the phenotype of Dent disease. Experiment Overall Design: Renal proximal tubules were dissected from wild type and Clcn5 knockout mice. Mice were anesthetized with halothane, the abdominal aorta of each animal was accessed and the left kidney was perfused with an ice-cold salt. Proximal tubule dissection was performed in an ice-cold salt solution. After dissection of approximately 80-100 segments of 2 mm in length per kidney, the RNA for 3-4 mice was combined to have enough RNA per chip. Experiment Overall Design: 3 microarrays each of wild type and knockout mouse proximal tubule were processed

PPARs and c-Myc regulate metabolism of renal tubules

Project description:Different segments of renal tubules have distinct metabolic features and functions, and defective metabolism in renal tubules is involved in the pathobiology of kidney diseases. However, the mechanisms underlying the metabolic regulation in renal tubules remain to be defined. We demonstrated that the renal proximal tubule (PT) has high expression of fatty acid and lipid metabolism enzymes, which is transcriptionally upregulated by abundantly expressed peroxisome proliferator-activated receptor (PPAR)/γ to support active lipid metabolism. In contrast, the renal distal tubule (DT) has elevated glycolytic enzyme expression corresponding with high rates of glycolysis, and this increased expression is mediated by abundantly expressed c-Myc. In addition, Nrf2 upregulated glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, and NADP-dependent malic enzyme 1 expression for NADPH production and antioxidation in the DT. Highly expressed PPARγ transcriptionally enhanced expression of the protease iRhom2 in the PT, which suppressed epidermal growth factor (EGF) expression and secretion, inhibiting EGF receptor activation-dependent glycolytic gene expression and maintaining the low level of glycolysis. PPARγ inhibition reduced iRhom2 expression and increased EGF and GLUT1 expression in the PT in mice, resulting in hypertrophy of renal tubules and inhibited kidney functions, which can be rescued by inhibition of glycolysis via treatment with 2-deoxy-D-glucose. These findings delineate instrumental molecular mechanisms underlying the active lipid metabolism and suppressed glycolysis in the PT and active glycolysis in the DT and reveal critical roles for PPARs and c-Myc in maintaining metabolic homeostasis in the kidney

Transcriptomes of Major Proximal-Tubule Cell-Culture Models

Project description:Purpose:Cultured cell lines are widely used for research in the physiology, pathophysiology, toxicology and pharmacology of the renal proximal tubule. The lines that are most appropriate for a given use depend on the genes expressed.We have used modern RNA-sequencing techniques to identify the gene expression profile of 14 different cell lines plus primary cultures of mouse proximal tubule and compare them to transcriptomes of native kidney proximal tubules. Methods: 14 different proximal tubule cell lines were grown on permeable supports under conditions specific for the respective lines. RNA-Seq followed standard procedures. Results and conclusion: Transcripts expressed in cell lines showed variable match to transcripts selectively expressed in native proximal tubule. Opossum kidney (OK) cells displayed the highest percentage match (45%) with pig kidney cells (LLC-PK1) close behind (39%). Much lower percentage matches were seen for various human lines including HK-2 cells (26%) and lines from rodent kidneys (18-23%).An online resource (https://esbl.nhlbi.nih.gov/JBrowse/KCT/) has been created for interrogation of the data.No cell line closely matched the transcriptome of native proximal tubule cells. However, some of the lines tested are suitable for the study of particular metabolic and transport processes seen in the proximal tubule.
