Project description:Autosomal Recessive Polycystic Kidney Disease (ARPKD) is a rare paediatric disease primarily caused by mutations in the gene PKHD1. ARPKD presents with considerably clinical variability which is linked to the type of PKHD1 mutation but not position. Animal models of Polycystic Kidney Disease (PKD) suggest there is a complex genetic landscape with genetic modifiers as a potential cause of disease variability. Transcriptomic analysis identified a considerable number of genes linked to cellular metabolism and development. Amongst these genes were those linked to WNT signalling. Two individuals in this cohort had the same mutations in PKHD1 but different rates of kidney disease progression. Amongst the transcriptomic differences of these two individuals were differences in the expression changes of WNT genes.

Project description:Autosomal recessive polycystic kidney disease (ARPKD) is caused by mutations in the PKHD1 gene in both humans and the orthologous PCK rat model. Although ARPKD results solely from PKHD1 mutations, the disease onset and severity are highly variable, indicating that other unknown genetic risk factor(s) modify ARPKD-associated phenotypes. To identify genetic modifiers of ARPKD severity, we created two genetically distinct Pkhd1 congenic rat strains on the Fawn-Hooded Hypertensive (FHH) and the Dahl S (SS) rat backgrounds (denoted FHH.Pkhd1 and SS.Pkhd1, respectively) that harbor the PCK-derived Pkhd1 allele. The FHH.Pkhd1 and SS.Pkhd1 strains had lower renal cyst formation at 30 days-of-age (5±2% and 8±2% cystic, respectively; P<0.001) compared to the PCK kidneys (26±4% cystic), which coincided with significantly reduced kidney weights in the FHH.Pkhd1 and SS.Pkhd1. Liver cyst formation and liver weight did not differ between PCK, FHH.Pkhd1, and SS.Pkhd1. These data indicated that the PCK genome harbors genetic modifier(s) of ARPKD severity that are not present in the FHH and SS genomes. Using high density SNP array genotyping and microarray expression analysis, we identified 50 potential modifiers of ARPKD severity in the PCK rat. Of these candidates, a damaging nonsynonymous variant in Nphp4 stood out as the most likely candidate based on variant segregation, protein modeling, network analysis, and gene ontology. Nphp4 is widely associated with the autosomal recessive cilliopathy and nephronopthisis, but had not been previously implicated in the molecular or cellular pathophysiology of ARPKD. Collectively, these data provide genetic evidence of disease modifier(s) in the PCK model of ARPKD and prioritized multiple candidates, including NPHP4, for further investigation in ARPKD pathogenesis. In this study, we used microarray to analyze transcript expression in the kidneys of 30 day old SD (n=4), PCK (n=4), FHH (n=4), FHH.Pkhd1 (n=4), SS (n=4), and SS.Pkhd1 (n=4). Samples were pooled and the pooled samples were run in triplicate. The 30 day timepoint was chosen because the differences in renal cyst formation between PCK, FHH.Pkhd1, and SS.Pkhd1 were greatest at this timepoint. To account for genetic strain differences that do not contribute to ARPKD severity, gene expression of each cystic rat strain was compared to its parental strain.

Project description:Autosomal recessive polycystic kidney disease (ARPKD) is a severe renal cystic disease mainly caused by PKHD1. However, its genetic cause, pathological features, and mechanism remained unsolved. Our findings may provide new insight on the pathophysiology of the polycystic kidney due to PKHD1 deficiency, and the PKHD1 mosaicism needs to be taken close attention in genetic testing of ARPKD.

Project description:Liver fibrosis usually involve different cell types interaction. Despite its devastating consequences, there are no treatments for liver fibrosis. Genome engineering and a human hepatic organoid system was used to produce the first naïve in vitro model including several crucial components contributed for liver fibrosis. Hepatic organoids engineered to express the most common causative mutation for Autosomal Recessive Polycystic Kidney Disease (ARPKD) developed abnormal bile ducts and hepatic fibrosis in only 21 days, which are the key features of ARPKD liver pathology. Singel cell level analysis indicated that the ARPKD mutation induced bile duct proliferation through several critial pathways, and appear to be actively involved in collagen fiber generation. Therefore, abnormal cholangiocytes promotes the expansion its counterpart , which collagen-producing myofibroblasts with a markedly increased level of PDGFRB protein expression and evidence of an activated STAT3 signalling pathway.

Project description:Autosomal recessive polycystic kidney disease (ARPKD) is a severe pediatric hepatorenal disorder with pronounced phenotypic variability. A substantial number of patients with early diagnosis reaches adulthood and some patients are not diagnosed until adulthood. Yet, clinical knowledge about adult ARPKD patients is scarce. Here, we describe forty-nine patients with longitudinal follow-up into young adulthood that were identified in the international ARPKD cohort study ARegPKD. Forty-five patients were evaluated in a cross-sectional analysis at a mean age of 21.4 (±3.3) years describing hepatorenal findings. Renal function of native kidneys was within CKD stages 1 to 3 in more than 50% of the patients. Symptoms of hepatic involvement were frequently detected. Fourteen (31%) patients had undergone kidney transplantation and six patients (13%) had undergone liver transplantation or combined liver and kidney transplantation prior to the visit revealing a wide variability of clinical courses. Hepatorenal involvement and preceding complications in other organs were also evaluated in a time-to-event analysis. In summary, we characterize the broad clinical spectrum of young adult ARPKD patients. Importantly, many patients have a stable renal and hepatic situation in young adulthood. ARPKD should also be considered as a differential diagnosis in young adults with fibrocystic hepatorenal disease.
