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

Project description: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.

Immunohistochemical Investigation for Renal Tubules in Adaptive and Maladaptive Repair Process after Renal Tubular Injury in the Kidney of Rats

Project description:Acute kidney injury (AKI) have been thought to be reversible condition, however, emerging evidence demonstrated association between AKI and subsequent development of irreversible fibrosis and chronic kidney disease. In the present study, since recovery of AKI depends on renal tubular regeneration, factors expressing in renal tubules in adaptive or maladaptive repair process were investigated to predict reversibility of kidney injury. In the kidney of female F344 rats subjected to ischemia/reperfusion (I/R), regenerative tubules and dilated tubules were observed at 3 and 7 days after I/R. In fibrotic areas of the kidney of male SD rats subjected to I/R, renal tubules were dilated or atrophied. From microarray data of regenerative tubules, survivin, sex-determining region Y (SRY)-box 9 (SOX9), and CD44 were extracted as factors possibly relating to tubular regeneration or fibrosis. Immunohistochmical analysis demonstrated that survivin and SOX9 expressed in regenerative tubules, while SOX9 also expressed in renal tubules in fibrotic area, indicating that survivin and SOX9 contribute renal tubular regeneration, but sustained SOX9 expression may lead fibrosis. CD44 expressed in dilated tubules at day 3 and 7, and tubules in fibrotic area, suggesting that CD44 expressed in maladaptive tubules. These information will be helpful to consider reversibility of kidney injury.

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

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

Epigenome analysis of clear cell renal cell carcinoma (ccRCC) tissue versus matched normal kidney tissue

Project description:Genome wide DNA methylation profiling of clear cell renal cell carcinoma (ccRCC) tissue versus matched normal kidney tissue. The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles across approximately 450,000 CpGs in tumor and adjacent normal kidney tissue samples from ccRCC patients. Samples included 46 paired fresh frozen ccRCC tumor and adjacent normal kidney tissues.

Isolation and characterization of progenitor-like cells from human renal proximal tubules

Project description:The adult kidney has a remarkable capacity for self-renewal upon damage. Whether this regeneration is mediated by dedifferentiating surviving cells or as recently suggested by stem cells has not been unequivocally settled. The stem cell concept is however hampered by lack of consensus regarding the histological localization of and defining markers for these cells. Here, we demonstrate that aldehyde dehydrogenase (ALDH) activity may be used for isolation of cells with progenitor-like characteristics from adult human renal cortical tissue. Gene expression profiling of the isolated ALDHhigh and ALDHlow cell fractions followed by immunohistochemical interrogation of renal tissues enabled us to delineate a tentative progenitor cell population with a scattered distribution in the epithelial layer of the proximal tubules (PT). The cells differed from the surrounding cells by expression of CD133, CD24, vimentin, KRT7, KRT19, and BCL2, and were negative for PT-specific markers. Based on functional and bioinformatic analyses as well as an immunophenotypical resemblance to cells of regenerating tubules we suggest that these cells are endowed with a more robust phenotype, allowing increased resistance to acute renal injury, enabling rapid repopulation of the tubules. The rare intratubular cells also displayed marked transcriptional and immunophenotypical similarities to that of cortical adenomas and papillary renal cell carcinomas, indicating that these renal neoplasms arise through oncogenic transformation of this subset of PT cells. Total RNA extracted from three pairs of ALDH-high and ALDH-low cell fractions were hybridized to Illumina humanHT-12 v3.0 Expression BeadChips (Illumina Inc) at the SCIBLU Genomics Centre at Lund University Sweden (http://www.lth.se/sciblu).
