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

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.

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).

Side Population Analysis in Clear Cell Renal Cell Carcinoma

Project description:Cancer stem cells have an important role in tumour biology. While their identity in haematological malignancies is clearly defined, stem cell identity remains elusive in some solid tumours. Clear cell renal cell carcinoma (ccRCC) represents the most common form of kidney cancer, but the identity or existence of ccRCC stem cells remains unknown. We aimed to discern their existence using the widely utilised side population approach in ccRCC cell lines. In all cells tested, a well-defined side population was identified, and cell-based assays suggested stem-like properties. However, limiting dilution assays revealed comparable tumour initiating abilities and tumour histology of side and non-side populations, and single cell RNA-sequencing revealed minimal differences between these populations. The results indicate that the side population approach is not sufficient for cancer stem cell discovery in ccRCC.

Gene expression profiles in isolated proximal tubules and whole kidneys of rats after cisplatin-administration

Project description:To clarify the effects of cisplatin (cis-diamminedichloroplatinum II, CDDP) on the gene expression profiles in renal proximal tubules, microarray analyses were carried out using total RNA samples isolated from microdissected proximal tubules and whole kidneys. The molecular events underlying acute kidney injury (AKI) in the proximal tubules of rats with cisplatin-induced nephrotoxicity were successfully clarified with 17,000 transcripts. Renal proximal tubules were isolated under microscopy, and transcriptome data were collected with Rat Genome Survey MicroarrayÂ® (Applied Biosystems)
