| الوصف: | Polycystic kidney diseases (PKD) are genetic disorders which disrupt kidney architecture and function. Autosomal recessive PKD (ARPKD) is a rare form of PKD, caused by mutations in PKHD1, and clinically more severe than the more common autosomal dominant PKD (ADPKD). Prior studies have implicated Hedgehog (Hh) signaling in ADPKD, with increased levels of Hh components in experimental ADPKD and reduced cystogenesis following pharmacological Hh inhibition. In contrast, the role of the Hh pathway in ARPKD is poorly understood. We hypothesized that Hh pathway activity would be elevated during ARPKD pathogenesis, and its modulation may slow disease progression. We utilized Cpk mice which phenocopy ARPKD and generated a PKHD1-mutant spheroid model in human collecting ducts. Significantly elevated levels of the Hh transcriptional effector Gli3 were found in Cpk mice, a finding replicated in PKHD1-mutant spheroids. In Cpk mice, total GLI3 and GLI3 repressor protein levels were also increased. Reduction of increased Gli3 levels via heterozygous genetic deletion in Cpk mice did not affect cyst formation. Additionally, lowering GLI3 transcripts to wildtype levels did not influence PKHD1-mutant spheroid size. Collectively, these data suggest attenuation of elevated Gli3 does not modulate murine and human models of ARPKD. |
