E-GEOD-67463 - Gonadal Identity in the Absence of pro-Testis Factor SOX9 and pro-Ovary Factor beta-catenin
Released on 26 May 2015, last updated on 30 May 2015
The main goal of our study is to identify the molecular events that determine the gonadal identity in mammals. Although testis and ovary arise from a common embryonic primordium, they represent outcomes of opposing fate determination. This decision to differentiate into a testis or an ovary hinges upon the balance between two antagonizing factors, pro-testis SOX9 and pro-ovary β-catenin. This microarray analysis led to the identification of the genes involved in the fate of XX and XY gonads in absence of SOX9 and beta-catenin We developed mouse genetic models that lack either Sox9, β-catenin, or both specifically in the somatic cells. All embryos used in this study resulted from the crossing between Ctnnb1f/f; Sox9f/f females with Sf1-cre+/Tg ; Ctnnb1+/f; Sox9+/f males. XX and XY fetal gonads were collected at embryonic day E14.5
