RNA seq comparative analysis of XX, XY, and XXTet3-/- mutant mouse embryonic stem cells versus XX, XY, and XXTet3-/- mutant epiblast-like cells

ABSTRACT: In XXTet3-/- mESCs DNA methylation levels are higher than XX wildtype levels. We sought to determine if changes in cytosine modifications observed in XXTet3-/- mESCs impacted gene expression, we performed RNA-seq. 104 genes were up regulated in the mutant XX mESCs relative to wild type controls, and 86 were down regulated To ask whether the XX-specific nuclear enrichment of TET3 is necessary for a developmental transition, we differentiated WT XX and XXTet3-/- mESCs into epiblast-like cells (EpiLCs). Comparison of WT XX and XXTet3-/- EpiLC RNA-seq showed that 404 genes exhibited increased expression and 499 exhibited decreased expression in mutant cells. GO term analysis showed gene expression changes affecting several LIF and BMP signaling pathways. However, despite these changes in signaling pathway driven expression, the expression of mESC markers went down and mEpiLC markers went up comparably upon differentiation WT XX and XXTet3-/- mESCs, suggesting that many key transcriptional changes that characterize this transition can occur without TET3.

Comparison of gene expression by RNA-seq in canine gonads from embryos at risk of XX Disorder of Sex Development (XX), male (XY) littermate controls, and age-matched female (XX) and male (XY) controls.

Project description:In a rare subtype of XX Disorder of Sex Development (DSD), individuals are negative for SRY, the testis determining factor on the Y chromosome, yet develop testes or ovotestes, and both of these phenotypes occur in the same family. This is a naturally occurring disorder in humans (Homo sapiens) and dogs (C. familiaris), and phenotypes in the canine XX DSD model are strikingly similar to those in this type of human XX DSD. The purposes of this study were to identify 1) a variant associated with XX DSD in the canine model and 2) gene expression alterations in canine embryonic gonads that could be informative to causation. Using a genome wide association study (GWAS) and whole genome sequencing (WGS), we identified a variant on C. familiaris autosome 9 (CFA9) that is significantly associated with XX DSD in the canine model and in affected purebred dogs. This is the first marker and candidate causative variant identified for inherited canine XX DSD. It lies within the canine ortholog for the human disorder (OMIM 278850), which resides on 17q24, upstream of SOX9. Gene expression studies (RNA-seq and PRO-seq) in embryonic gonads at risk of XX DSD from the canine model identified significant RSPO1 downregulation in comparison to XX controls, without significant upregulation of SOX9 or other known testis pathway genes. A novel mechanism is proposed in which the canine XX DSD variant acts upstream of RSPO1 to induce epigenomic gonadal mosaicism.

Transcription profiling of XX and XY sorted mouse somatic support cells and XX and XY mouse whole gonads to identify potential new mammalian gonadal sex determining genes.

Project description:Gonadal sex determining (GSD) genes that initiate fetal ovarian and testicular development and differentiation are expressed in the cells of the urogenital ridge that differentiate as somatic support cells (SSCs), i.e., granulosa cells of the ovary and Sertoli cells of the testis. To identify potential new mammalian GSD genes, we analyzed the gene expression differences between XX and XY SSCs cells isolated from the gonads of embryonic day (E) 13 mouse fetuses carrying an EGFP reporter transgene expressed specifically in SSCs. In addition, genome wide expression differences between XX and XY E13 whole gonads were examined. Newly identified differentially expressed transcripts are potential GSD genes involved in unexplained human sex reversal cases. Experiment Overall Design: Two seperate RNA samples were obtained from E13 XX and XY sorted EGFP+ cells, and two seperate RNA samples were obtained from E13 XX and XY pooled gonads. Approximately 20ng of total RNA from each sample was used to generate biotin-labelled cDNA. Approximately 2.5ug biotin labelled cDNA of each sample was used for each Mouse Genome 430v2.0 GeneChip array (Affymetrix). Significantly differentially expressed transcripts were identified using R/maanova. Statistical significance was determined at a false discovery rate value of equal to or less than 1%.

Effects of the sex chromosome complement, XX, XO or XY, on the transcriptome and development of mouse oocytes during follicular growth.

Project description:Purpose: To understand how sex chromosome complement, XX, XO and XY, influences the transcriptome in the oocytes of grwoth phase. Methods: Oocytes of 50 and 60 µm in diameter were isolated from mouse ovaries at 18 dpp and subject to RNA-sequencing. Results: (1) Many X-linked genes are subject to X chromosome dosage dependent expression. (2) Many genes are expressed from both short and long arms of the Y chromosome. (3) The transcriptome landscape in XY oocytes is closer to XX oocytes than XO oocytes. (4) About 10 genes are differentially expressed in XY oocytes compared to XX or XO oocytes. Conclusions: The differences in XY oocytes became exacerbated to differ from XX or XO oocytes near the end of growth phase.

Genomic imprinting of XX spermatogonia and XX oocytes recovered from XX<-->XY chimeric testes.

Project description:We produced XX<-->XY chimeras by using embryos whose X chromosomes were tagged with EGFP (X*), making the fluorescent green female (XX*) germ cells easily distinguishable from their nonfluorescent male (XY) counterparts. Taking advantage of tagging with EGFP, the XX* "prospermatogonia" were isolated from the testes, and the status of their genomic imprinting was examined. It was shown that these XX cells underwent a paternal imprinting, despite their chromosomal constitution. As previously indicated in sex-reversal XXsxr testes, we also found a few green XX* germ cells developed as "eggs" within the seminiferous tubules of XX*<-->XY chimeric testes. These cells were indistinguishable from XX* prospermatogonia at birth but resumed oogenesis in a testicular environment. The biological nature of the "testicular eggs" was examined by recovering the eggs from chimeric testes. The testicular eggs not only formed an egg-specific structure, the zona pellucida, but also were able to fuse with sperm. The collected testicular eggs were indicated to undergo maternal imprinting, despite the testicular environment. The genomic imprinting did not always follow the environmental conditions of where the germ cells resided; rather, it was defined by the sex that was chosen by the germ cells at early embryonic stage.

Tet-dependent transcriptional programs during mESC differentiation

Project description:Tet-family dioxygenases catalyze conversion of 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC) in DNA. Here, we show that Tet3 deficiency impairs neural differentiation of mouse ESCs, resulting in skewing towards cardiac mesoderm; conversely, ectopic expression of Tet3 enhances neural differentiation and limits cardiac mesoderm specification. To determine the effects of Tet3 gain and loss on global gene expression profiles during mESC differentiation, we performed whole transcriptome RNA-sequencing (RNA-seq) analysis of (i) WT and Tet3 KO mESCs differentiating into neuroectoderm under SFEB culture (days 6 and 10); and (ii) Control and Tet3-overexpressing mESCs in non-permissive neural differentiation conditions containing FBS (days 4 and 7). Genome-wide analyses showed that Tet3 mediates cell-fate decision by inhibiting Wnt signaling.
