Project description:Changes in gene expression levels were identified by microarray. Samples were human kidney epithelial cell lines derived from patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD) and unaffected controls. Autosomal Dominant Polycystic Kidney Disease (ADPKD), the most common inherited kidney disease, is due to mutations in PKD1 (85%) or PKD2 (15%) but has a highly variable phenotypic disease expression. We conducted parallel microarray profiling in normal and diseased human PKD1 cystic kidney cells to identify altered signatures of microRNA and mRNA target genes potentially implicated in disease expression.

Project description:Polycystic Kidney Disease (PKD) is a genetic disease of the kidney characterized by the gradual replacement of normal kidney parenchyma by fluid-filled cysts and fibrotic tissue. Autosomal Dominant Polycystic Kidney Disease (ADPKD) is caused by mutations in the PKD1 or PKD2 gene. Here we present an RNASeq experiment designed to investigate the effect of a kidney specific and Tamoxifen inducible knockout of the Pkd1 gene in mice. 7 mice were grouped into two groups, 4 Tamoxifen treated mice which develop an adult onset Polycystic Kidney Disease phenotype and 3 untreated mice which have WT phenotype.

Here we present an RNASeq experiment designed to investigate the effect of a kidney specific and Tamoxifen inducible knockout of the Pkd1 gene in mice. The Pkd1cko mice were harvested at different time points 2-weeks, 3-weeks, 5-weeks, 10.5-weeks, 11-weeks and 15-weeks after gene inactivation.

Project description:Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a genetic disorder caused by loss-of-function mutations in PKD1 or PKD2. Increased glycolysis is a prominent feature of the disease, but how it impacts on other metabolic pathways is unknown. Here, we present an analysis of mouse Pkd1 mutant cells and kidneys to investigate the metabolic reprogramming of this pathology. We show that loss of Pkd1 leads to profound metabolic changes that affect glycolysis, mitochondrial metabolism, and fatty acid synthesis (FAS). We find that Pkd1-mutant cells preferentially use glutamine to fuel the TCA cycle and to sustain FAS. Interfering with either glutamine uptake or FAS retards cell growth and survival. We also find that glutamine is diverted to asparagine via asparagine synthetase (ASNS). Transcriptional profiling of PKD1-mutant human kidneys confirmed these alterations. We find that silencing of Asns is lethal in Pkd1-mutant cells when combined with glucose deprivation, suggesting therapeutic approaches for ADPKD.

Project description:Mutations in PKD1 cause Autosomal Dominant Polycystic Kidney Disease (ADPKD). To further investigate the impact of Pkd1 knockout on renal tubular cells, a direct reprogramming approach was applied. After direct reprogramming of mouse embryonic fibroblasts to induced renal tubular epithelial cells (iRECs), Pkd1 knockout iREC clones were generated by Cre-mediated recombination of floxed Pkd1 alleles. The knockout clones were compared to their corresponding wild type clones by RNA Sequencing and transcriptome profiling.

Project description:ADPKD (Autosomal dominant polycystic kidney disease) is the most common inherited disorders and is characterized by growth of numerous cysts filled with fluid in the kidneys. Ultimately, it leads to kidney failure. The mutations of PKD1 and PKD2 account for approximately 85 and 15 percent of ADPKD, respectively. However, the mechanisms related to genetic mutation of PKD1 and PKD2 are still unclear. To investigate altered gene expression levels, Affymetrix microarray was performed using the kidney tissue from normal and ADPKD patients.

Project description:To elucidate the molecular pathways that modulate renal cyst growth in autosomal dominant polycystic kidney disease (ADPKD) Keywords: Disease state analysis We performed global gene profiling on renal cysts of different size (small cysts: less than 1 ml, n=5; medium cysts: between 10-25 ml, n=5; large cysts: greater than 50 ml, n=3) and minimally cystic tissue (MCT, n=5) from five PKD1 polycystic kidneys. Additionally, non-cancerous renal cortical tissue from three nephrectomized kidneys with isolated renal cell carcinoma was used as normal control tissue (n=3). This dataset is part of the TransQST collection.

Project description:Autosomal Dominant Polycystic Kidney Disease (ADPKD; MIM ID’s 173900, 601313, 613095) leads to end stage kidney disease, caused by mutations in PKD1 or PKD2. Inactivation of Pkd1 before or after P13 in mice results in distinct early- or late-onset disease. Using a mouse model of ADPKD carrying floxed Pkd1 alleles disrupted using a tamoxifen-inducible Cre recombinase, transcriptomics and metabolomics were applied to follow disease progression in animals induced before P10. Network analysis suggests that Pkd1-cystogenesis does not cause developmental arrest and occurs in the context of gene networks similar to those that regulate/maintain normal kidney morphology/function. These analyses also predict metabolic pathways, notably those controlled by HNF4α, are key elements in postnatal kidney maturation and early steps of cyst formation. To test this hypothesis, metabolic networks were altered by inactivating Hnf4a and Pkd1. The Pkd1/Hnf4a double knock-out have significantly more cystic kidneys thus indicating that modulating metabolic pathways might be an effective therapeutic approach.
