Gonads gene expression profiling in WT and Sox9flox/flox; Sf1:creTr/+ mice

ABSTRACT: In mammals, gonadal differentiation is the first step of sex determination, and the transcription factor Sox9 promotes testis differentiation. Here we used the XY Sox9flox/flox; Sf1:creTr/+ mouse model and show that the lack of Sox9 expression induces a full sex reversal of E13.5 XY Sox9flox/flox; Sf1:creTr/+ gonads compared to XY Sox9flox/flox. Keywords: gonads gene expression profiling in WT and Sox9flox/flox; Sf1:creTr/+ mice 3 WT versus 3 Sox9flox/flox; Sf1:creTr/+ mice.

Gonadal Identity in the Absence of pro-Testis Factor SOX9 and pro-Ovary Factor beta-catenin

Project description: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

RNA-seq of bovine genital ridges from male and female fetuses at three different time points corresponding to sex determination and early differentiation of the gonads

Project description:The aim of the study was to identify differentially expressed genes during Gonadal Sex Determination in cattle. We performed a Rna-Seq analysis of XX and XY gonads during sex determination on embryonic days 35 (D35), 39 (D39) and 43 (D43). RNA-seq libraries were prepared from grouped gonads from D35, D39 and D43 males and females.

RNA-seq of mice genital ridges from males and females at embryonic days E11 and E12

Project description:The aim of the study was to identify differentially expressed genes, isoforms and AS modifications accompanying Gonadal Sex Determination in mice. We performed a Rna-Seq analysis of XX and XY gonads during sex determination on embryonic days 11 (E11) and 12 (E12). RNA-seq libraries were prepared from grouped gonads from E11 and E12 males and females. The cDNA libraries were sequenced using a HiSeq2500 v4 chemistry system

Expression analysis of Wv/Wv fetal gonads

Project description:Following sex determination, XY and XX gonads develop into a testis and an ovary, respectively. Depending on the sex of the gonad, resident germ cells will subsequently be committed to either spermatogenesis or oogenesis. In this study we took advantage of the Wv/Wv mouse genetic model, in which gonads are almost devoided of germ cells, to uncover gene expression underlying fetal germ cell development. Male and Female gonads were collected at 12, 14 and 16 days post coitum (dpc) from wild-type and Wv/Wv mouse embryos. Total RNAs were extracted and hybridized on Affymetrix microarrays. Expression signals from male and female gonads or from wild-type and mutant gonads were compared to identify sexually dimorphic genes as well as genes expressed in germ cell during fetal gonad development.

Reprogramming of somatic cell fate in fetal mouse testis by FOXL2

Project description:From fish to human, FOXL2 is considered one of the most conserved markers of ovarian granulosa cell identity. To determine if the sole expression of FOXL2 can determine ovarian differentiation, we created a mouse model that allows the conditional expression of FOXL2. Rosa26-CAG-LSL-Foxl2 mice were crossed to Sf1-Cre mice to induce the expression of FOXL2 in the SF1+ somatic cells of the fetal gonads.When FOXL2 was induced in the somatic cells of the undifferentiated testis, the Sertoli cells and consequently the other cell lineages composing the fetal gonads were feminized, resulting in a partial testis-to-ovary sex reversal We created a mouse genetic model that conditionaly express FOXL2 in the somatic cells of the fetal gonads. All embryos used in this study resulted from the crossing between Rosa26-CAG-LSL-Foxl2+/f and Sf1-cre+/Tg mice. XX and XY fetal gonads were collected at embryonic day E14.5. This microarray analysis led to the identification of the genes misregulated upon ectopic induction of FOXL2 in the fetal testis, and showed that FOXL2 expression resulted in feminization of both somatic and germ cells of the fetal gonad.

Transcription profiling of mouse embryonic day (E) 11.5 and E12.5 mouse gonadsNew candidate gene identification for controlling mammalian gonadal sex determination

Project description:Mammalian gonadal sex determination is dependent on proper expression of sex determining genes in fetal gonadal somatic support cells (i.e., pre-granulosa and pre-Sertoli cells in XX and XY gonads, resp.). We used a unique transgenic mouse strain combined with microarray profiling to identify all the differentially expressed transcripts in XX and XY isolated somatic support cells during critical stages of gonadal development and differentiation. Experiment Overall Design: XX and XY somatic support cells (SSC) were isolated by flow cytometry from embryonic day (E) 11.5 and E12.5 mouse gonads. Total RNA was isolated from pools of isolated cells; 3 pools per sex and each timepoint.

Expression analyses to identify genes involved in testis-specific vascular development

Project description:One of the earliest morphological changes during testicular differentiation is the establishment of an XY specific vasculature. The testis vascular system is derived from mesonephric endothelial cells that migrate into the gonad. In the XX gonad, mesonephric cell migration and testis vascular development is inhibited by WNT4 signaling. In Wnt4 mutant XX gonads, endothelial cells migrate from the mesonephros and form a male-like coelomic vessel. Consequently, the XX Wnt4 mutant mice presented an opportunity to focus a gene expression screen on the processes of mesonephric cell migration and testicular vascular development. We compared differences in gene expression between XY Wnt4+/+ and XX Wnt4+/+ gonads and between XX Wnt4-/- and XX Wnt4+/+ gonads to identify genes similarly upregulated in wildtype XY gonads and XX mutant gonads that might play important roles in testis-specific vascular development. Keywords: genetic sex and phenotypic comparisons
