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.

To investigate altered gene expression levels, Affymetrix microarray was performed using the kidney tissue from normal and ADPKD patients. Total RNAs were isolated from kidney of human normal (49 years old/ male) and ADPKD patients (62 years old/ male, 67 years old/ male) using NucleoSpin® RNA Kit (MACHEREY-NAGEL) according to the manufacturer’s instructions. We used tha Affymetrix GeneChip Human Gene 1.0 ST Array. Per RNA sample, 300 ng was used as the input into the Affymetrix procedure as recommended by the manufacturer's protocol.

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: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:Little is known about the genes involved in the initial cyst formation and disease progression in autosomal dominant polycystic kidney disease (ADPKD). To uncover the genetic determinants and molecular mechanisms of ADPKD, we analyzed 4-point time-series DNA microarrays from Pkd1L3/L3 mice to generate high-resolution gene expression profiles at different stages of disease progression. We found different characteristic gene expression signatures in the kidneys of Pkd1L3/L3 mice compared to age-matched controls during the initial phase of the disease. By postnatal week 1, the Pkd1L3/L3 kidney already had a distinctive gene expression pattern considerably different from the corresponding normal controls. The genes differentially expressed, either induced or repressed, in ADPKD are important in immune defense, cell structure and motility, cellular proliferation, apoptosis and metabolic processes, and include members of three pathways (Wnt, Notch, and BMP) involved in morphogenetic signaling. Further analysis of the gene expression profiles from the early stage of cystogenesis to end stage disease identified a possible gene network involved in the pathogenesis of ADPKD.

Project description:Background: In autosomal dominant polycystic kidney disease (ADPKD) there is an unmet need for early markers of rapid disease progression to facilitate counseling and selection for kidney-protective therapy. Our aim was to identify markers for rapid disease progression in urinary extracellular vesicles (uEVs). Methods: uEVs were isolated at baseline in two independent cohorts including patients with rapid disease progression and stable disease; patients were matched by age, sex, total kidney volume and mutation. uEV biomarker candidates were identified by mass spectrometry and further analyzed in a third and fourth cohort using immunoblotting and an enzyme-linked immunosorbent assay (ELISA). Single-nucleotide RNA sequencing of healthy and ADPKD tissue was used to confirm findings and identify the cellular origin of the uEV biomarker. Results: In the first two cohorts matrix metalloproteinase-7 (MMP-7) was significantly higher in uEVs of patients with rapid disease progression compared to stable disease. In the third cohort, immunoblotting confirmed a >2-fold increase in uEV-MMP-7 in patients with rapid disease progression compared to stable disease. In the fourth cohort, whole urine rather than uEVs were analyzed with MMP-7 ELISA demonstrating a significant but weak correlation with kidney function decline. Single-nucleotide RNA sequencing showed higher MMP-7 expression in ADPKD kidney tissue than in healthy kidney tissue and localized MMP-7 to the proximal tubule and thick ascending limb. Conclusion: uEV-associated MMP-7 is elevated in ADPKD patients with rapid disease progression and should be further investigated as predictive biomarker. Our findings also suggests that MMP-7 performs better when analyzed in uEVs than in whole urine.

Further analysis of the gene expression profiles from the early stage of cystogenesis to end stage disease identified a possible gene network involved in the pathogenesis of ADPKD. A total of 13 microarray data sets were generated with RNA samples from age-matched control and disease littermates at the four time points, with at least three biological replicates for each time point (PNW1, n = 3; PNW2, n = 4; PNW3, n = 3; PNW3.5, n = 3). 13 2-color experiments including: 3 replicates of: Wt mice vs. Pkd1L3/L3 mice at PNW 1 4 replicates of: Wt mice vs. Pkd1L3/L3 mice at PNW 2 3 replicates of: Wt mice vs. Pkd1L3/L3 mice at PNW 3 3 replicates of: Wt mice vs. Pkd1L3/L3 mice at PNW 3.5

Project description:Microvescicles (MV) and exosomes (EX) seem to be involved in the pathogenetic machinery of the autosomal dominant polycystic kidney disease (ADPKD), but, at the moment, no studies have assessed their role in medullary sponge kidney disease (MSK), a sporadic kidney malformation featuring cysts, nephrocalcinosis and recurrent renal stones. To discover their role in this disease we employed a proteomic-based research strategy.

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.
