Project description:The kidney has limited capacity to regenerate following injury and preferentially repairs chronic injury with secreted extracellular matrix proteins. This can be a progressive process with functioning kidney tissue being replaced detrimentally with fibrotic scar tissue, ultimately leading to kidney failure. Whilst the renal response to injury has been well described it has been examined at whole organ resolution and there has been very limited description of the contribution of individual cells to the kidney’s reparative ability. Using the reversible unilateral ureteric obstruction model, a model of reversable injury, we describe the transcriptomic changes that occur during obstructive renal injury and subsequent repair at a single cell resolution and describe the altered myeloid cell populations and kinetics likely involved in ongoing tissue repair.

Project description:Chronic kidney disease (CKD) is a burden for Public Health and concerns millions of individuals worldwide. Independently of the cause, CKD is secondary to the replacement of functional renal tissue by extra-cellular matrix proteins (i.e fibrosis) that progressively impairs kidney function. The pathophysiological pathways that control the development of renal fibrosis are common to most of the nephropathies involving native kidneys or kidney grafts. Unfortunately, very few treatments are available to stop renal fibrosis and most of the therapeutic strategies are often barely able to slow down the progression of fibrogenesis in native kidneys. Therefore, it is mandatory to discover new therapeutic pathways to stop renal fibrosis. Our objective is to study new pathways involved in renal fibrosis. We thus decided to use the model of Unilateral Ureteral renal Obstruction in mice, a fast and reproducible experimental model of renal fibrosis. We studied renal fibrosis using experimental model of ureteral unilateral obstruction in mice, which was performed by complete ligation of the left ureter. The control lateral right kidney served as internal control.

Project description:Grb2 is a small SH2-SH3 adaptor molecule that interacts with activated tyrosine kinase receptors (RTKs), providing a crucial link towards downstream activation of pro-proliferative and pro-survival ERK and Akt signaling pathways. Ret and FGFR2, two RTKs that interact with Grb2, play important roles in ureteric branching and the proper establishment of the renal collecting duct system, but it is unclear whether Grb2 is required in this process. In this study, we selectively ablated a conditional floxed allele of the Grb2 gene within the ureteric epithelial lineage in mice and demonstrate that Grb2 signaling is essentially required for proper collecting duct development. Ureteric Grb2 deficiency results in perinatal lethality and severe renal hypodysplasia closely reminiscent of the rudimentary kidney phenotypes observed in Ret-null mutant mice. Grb2 loss attenuates ERK and Akt activation in the ureteric epithelia resulting in pronounced impairment of ureteric branching. Gene expression analysis reveals that Grb2 deficiency results in defective induction of genes implicated in both ureteric branching and reciprocal mesenchymal metanephric induction. Our findings therefore strongly indicate that Grb2 is a physiologically-relevant major RTK signaling relay partner that promotes renal branching morphogenesis and the proper development of the collecting duct system and the urogenital tract. Microarray was used to profile and compare the transcriptomes of developing kidneys of E14.5 Grb2 conditional knockout (ureteric-bud specific) and wild-type embryos

Project description:To find miRNAs that involve in renal epithelial transition and renal fibrosis, we performed unilateral ureteral obstruction of mice for 7 days. After that, we harvested kidneys, and performed microarray of miRNA. Contralateral kidneys without ureteral obstruction were used as controls. miRNAs were purified from kidneys with ureteral obstruction and contralateral kidneys without ureteral obstruction. Then microarray of miRNA was performed (n=4). miRNAs up-regulated in kidneys with ureteral obsctruction compared with contralateral kidneys were sorted. We performed unilateral ureteral obstruction of mice for 7 days, and harvested kidneys.

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.

Project description:Tissue inhibitors of metalloproteinases (TIMP) are endogenous inhibitors of matrix metalloproteinases (MMP). While TIMP2 and TIMP3 inhibit MMPs, TIMP3 also inhibits activation of pro-MMP2 whereas TIMP2 promotes it. Here we assessed the differential role of TIMP2 and TIMP3 in renal injury using the unilateral ureteral obstruction model. Gene microarray assay showed that post-obstruction, the lack of TIMP3 had a greater impact on gene expression of intermediate, late injury- and repair-induced transcripts, kidney selective transcripts and solute carriers. Renal injury in TIMP3-/-, but not in TIMP2-/- mice increased expression of collagen type I/III, connective tissue growth factor, transforming growth factor-β and the downstream Smad2/3 pathway. Interestingly, ureteral obstruction markedly increased MMP2 activation in the kidneys of TIMP3-/- mice which was completely blocked in the kidneys of TIMP2-/- mice. These changes are consistent with enhanced renal tubulointerstitial fibrosis in TIMP3-/- and its reduction in TIMP2-/- mice. The activity of tumor necrosis factor-α converting enzyme, caspase-3 and mitogen activated kinases were elevated in the kidneys of TIMP3-/- but not TIMP2-/- mice, suggesting enhanced activation of apoptotic and pathological signaling pathways only in the obstructed kidney of TIMP3-/- mice. Thus, TIMP2 and TIMP3 play differential and contrasting roles in renal injury, TIMP3 protects from damage whereas TIMP2 promotes injury through MMP2 activation.

Project description:We aimed to define epithelial-specific genes in the kidney. In the developing mouse kidney at E12.5 epithelial cells are restricted to the ureteric bud, while mesenchymal cells surrounding the ureteric bud are non-epithelial. The mouse renal epithelial cell line mIMCD-3 was used to represent kidney epithelia in vitro. Gene expression was analyzed using Affymetrix microarrays in ureteric bud stalks, ureteric bud tips, and mIMCD-3 cells and compared to metanephric mesenchyme.
