Project description:Autosomal dominant polycystic kidney disease (ADPKD) is characterized by mutations in either the PKD1 or PKD2 genes leading to progressive cyst growth and often ESKD. We have previously demonstrated that with loss of Pkd1 the tubules can enlarge without an increase in tubular cell numbers, suggesting that tubular basement membrane remodeling is important for cystic dilation. Here we compared the transcriptomes from inducible tubule-specific knock out of Pkd1 (PkdTKO) and the uninduced littermate mice kidneys as controls. RNA sequencing revealed significant upregulation of 17 metalloproteinases. Of these, A Disintegrin and Metalloproteinase with Thrombospondin Motif 1 (Adamts1), expressed primarily by the proximal tubule, is the most significantly upregulated following loss of Pkd1 expression. Upregulation of Adamts1 in PkdTKO kidneys correlated with a significant increase in the 70 kDa cleavage product of the V1 isoform of versican, which localized to the tubule basement membrane (TBM) and adjacent interstitial mononuclear cells. Simultaneous deletion of both Adamts1 and Pkd1 (P/ATKO) reduced Adamts1 expression levels by >90%, prevented V1 versican cleavage, and reduced interstitial macrophage accumulation and activation. P/ATKO mice demonstrated slower cystic enlargement, improved BUN and creatinine and better survival than did PkdTKO mice. In conclusion, preventing Adamts1 upregulation following loss of tubular Pkd1 expression effectively reduced macrophage accumulation and TBM remodeling, slowing cyst growth and preserving renal function.

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.

Project description:Autosomal dominant polycystic kidney disease (ADPKD) is characterized by cyst formation throughout the kidney parenchyma. It is caused by mutations in either of two genes, PKD1 and PKD2. Mice that lack functional Pkd1 (Pkd1null/null), develop rapidly progressive cystic disease during embryogenesis, and serve as a model to study human ADPKD. We examined the molecular pathways that modulate renal cyst growth in the Pkd1null/null model by performing global gene-expression profiling in embryonic kidneys at day 14 and 17. Gene Ontology and gene set enrichment analysis were used to identify overrepresented signaling pathways in Pkd1null/null kidneys. We found dysregulation of developmental, metabolic, and signaling pathways (e.g. Wnt, calcium, TGF-b and MAPK) in Pkd1null/null kidneys. Total RNA were obtained from kidneys of wild-type and Pkd1null/null animals at embryonic ages 14.5 and 17.5.

Project description:Background: Autosomal dominant polycystic kidney disease (ADPKD) affects more than 12 million people worldwide. Mutations in PKD1 and PKD2 cause cyst formation through unknown mechanisms. To unravel the pathogenic mechanisms in ADPKD, multiple studies have investigated transcriptional mis-regulation in cystic kidneys from patients and mouse models, and numerous dysregulated genes and pathways have been described. Yet, the concordance between studies has been rather limited. Furthermore, the cellular and genetic diversity in cystic kidneys has hampered the identification of mis-expressed genes in kidney epithelial cells with homozygous PKD mutations, which are critical to identify polycystin-dependent pathways.

Project description:Human pluripotent stem cell-derived organoids are models for human development and disease. We report a modified human kidney organoid system that generates thousands of similar kidney organoids, each consisting of 1 to 2 nephron-like structures. Single-cell transcriptomic profiling and immunofluorescence validation highlighted patterned nephron-like structures, utilizing similar pathways, with distinct morphogenesis, to human nephrogenesis. To examine this platform for therapeutic screening, the polycystic kidney disease genes PKD1 and PKD2 were inactivated by gene-editing. PKD1 and PKD2 mutant models exhibited efficient and reproducible cyst formation. Cystic outgrowths could be propagated for months to centimeter-sized cysts. To shed new light on cystogenesis, 247 protein kinase inhibitors (PKI) were screened in a live imaging assay identifying novel compounds blocking cyst formation but not overall organoid growth. Scaling and further development of the organoid platform will enable a broader capability for kidney disease modeling and high-throughput drug screens.

We crossed fifth-generation C57/BL6 Pkd1cond mice to fifth-generation C57/BL6 tamoxifen-Cre (B6.Cg-Tg(Cre/Esr1)5Amc/J mice (stock 004682), Jackson Laboratories) and C57/BL6 congenic B6.129S4-Gt(ROSA)26Sortm1Sor/J (stock 003474, Jackson Laboratories) to produce Pkd1 conditional mice with TamCre (mutant) or without TamCre (control). We induced Cre recombinase activity in mice < 10 days of age by intraperitoneally injecting nursing mothers with tamoxifen (10 mg/40 g) , and harvested kidney samples of control and mutant (34 and 36 animals, respectively) between the ages of 11 and 24 days.

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. 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: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.
