These polycystins form a cilia-localized complex that, when mutated, fails to inhibit an uncharacterized cilia-dependent cyst activation (CDCA) signal. This leads to progressive bilateral cyst growth and ultimately compromised renal function. Previous in vitro and in vivo studies from our group have demonstrated that Hedgehog (Hh) signaling inhibition reduces renal cystic severity in PKD models. To further investigate, we inactivated several Hh pathway components (Gli1, Gli2, Gli3 and Smo) in a Pkd1 hypomorphic mouse model through conditional deletion by tamoxifen-induced Cre-Lox recombination. We assessed cystic severity using kidney weight assessment and a microcomputed tomography (micro-CT)-based 3D imaging assay. Contrary to expectations, inactivation of Gli1 and Smo significantly increased cystogenesis. These findings suggest that Hh signaling does not mediate the CDCA signal.<\/jats:p>","DOI":"10.1242\/jcs.264133","type":"journal-article","created":{"date-parts":[[2025,6,24]],"date-time":"2025-06-24T16:30:37Z","timestamp":1750782637000},"source":"Crossref","is-referenced-by-count":6,"title":["Inhibition of Hedgehog signaling does not mitigate polycystic kidney disease severity in a <i>Pkd1<\/i> mutant mouse model"],"prefix":"10.1242","volume":"138","author":[{"given":"Sean K.","family":"Gombart","sequence":"first","affiliation":[{"name":"Center for Developmental Biology and Regenerative Medicine, Seattle Children's Research Institute 1 , Seattle, WA 98101 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott","family":"Houghtaling","sequence":"additional","affiliation":[{"name":"Center for Developmental Biology and Regenerative Medicine, Seattle Children's Research Institute 1 , Seattle, WA 98101 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tzu-Hua","family":"Ho","sequence":"additional","affiliation":[{"name":"Center for Developmental Biology and Regenerative Medicine, Seattle Children's Research Institute 1 , Seattle, WA 98101 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0325-8520","authenticated-orcid":false,"given":"David R.","family":"Beier","sequence":"additional","affiliation":[{"name":"Center for Developmental Biology and Regenerative Medicine, Seattle Children's Research Institute 1 , Seattle, WA 98101 ,","place":["USA"]},{"name":"University of Washington School of Medicine 2 Department of Pediatrics, Division of Genetic Medicine , , Seattle, WA 98195 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","published-online":{"date-parts":[[2025,7,31]]},"reference":[{"key":"2025073106395066200_JCS264133C1","doi-asserted-by":"publisher","first-page":"1392","DOI":"10.1016\/j.kint.2021.01.028","article-title":"The genetic background significantly impacts the severity of kidney cystic disease in the Pkd1(RC\/RC) mouse model of autosomal dominant polycystic kidney disease","volume":"99","author":"Arroyo","year":"2021","journal-title":"Kidney Int."},{"key":"2025073106395066200_JCS264133C2","doi-asserted-by":"publisher","first-page":"4753","DOI":"10.1242\/dev.129.20.4753","article-title":"Gli2, but not Gli1, is required for initial Shh signaling and ectopic activation of the Shh pathway","volume":"129","author":"Bai","year":"2002","journal-title":"Development"},{"key":"2025073106395066200_JCS264133C3","doi-asserted-by":"publisher","first-page":"1670","DOI":"10.1093\/brain\/awab083","article-title":"The hedgehog pathway suppresses neuropathogenesis in CD4 T cell-driven inflammation","volume":"144","author":"Benallegue","year":"2021","journal-title":"Brain"},{"key":"2025073106395066200_JCS264133C4","doi-asserted-by":"publisher","first-page":"2093","DOI":"10.1242\/dev.015990","article-title":"Gli3 coordinates three-dimensional patterning and growth of the tectum and cerebellum by integrating Shh and Fgf8 signaling","volume":"135","author":"Blaess","year":"2008","journal-title":"Development"},{"key":"2025073106395066200_JCS264133C5","doi-asserted-by":"publisher","first-page":"1553","DOI":"10.1152\/physrev.00018.2024","article-title":"Physiologic mechanisms underlying polycystic kidney disease","volume":"105","author":"Boletta","year":"2025","journal-title":"Physiol.
