In the red-eared slider turtle, Dmrt1 acts as the primary activator of the testis pathway. Removal of the repressive histone modification H3K27me3 from Dmrt1 by the histone demethylase KDM6B is required for its activation. We hypothesized that a similar de-repression mechanism is used in mammals to activate the testis pathway. Using a mouse knockout model for Kdm6b, we found that loss of Kdm6b leads to a delay in Sry activation and the development of an ovotestis. These results implicate KDM6B as a conserved regulator at the top of the sex determination cascade in both reptiles and mammals.<\/jats:p>","DOI":"10.1242\/dev.204724","type":"journal-article","created":{"date-parts":[[2025,5,23]],"date-time":"2025-05-23T10:17:45Z","timestamp":1747995465000},"source":"Crossref","is-referenced-by-count":8,"title":["KDM6B is a conserved activator at the top of the male sex determination pathway"],"prefix":"10.1242","volume":"152","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4607-2715","authenticated-orcid":false,"given":"Shannon M.","family":"Dupont","sequence":"first","affiliation":[{"name":"Duke University Medical Center Department of Cell Biology , , Durham, NC 27710 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2137-6114","authenticated-orcid":false,"given":"Alexandra","family":"Garcia-Moreno","sequence":"additional","affiliation":[{"name":"Duke University Medical Center Department of Cell Biology , , Durham, NC 27710 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4919-2715","authenticated-orcid":false,"given":"Eleanore V.","family":"O'Neil","sequence":"additional","affiliation":[{"name":"Duke University Medical Center Department of Cell Biology , , Durham, NC 27710 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6587-0969","authenticated-orcid":false,"given":"Blanche C.","family":"Capel","sequence":"additional","affiliation":[{"name":"Duke University Medical Center Department of Cell Biology , , Durham, NC 27710 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","published-online":{"date-parts":[[2025,6,13]]},"reference":[{"key":"2025061315010501900_DEV204724C1","doi-asserted-by":"publisher","first-page":"92","DOI":"10.1006\/dbio.2001.0438","article-title":"Evidence that sry is expressed in pre-sertoli cells and sertoli and granulosa cells have a common precursor","volume":"240","author":"Albrecht","year":"2001","journal-title":"Dev.
