Project description:Gobal expression analysis in four somatic tissues (brain, liver, kidney and muscle) of adult 40,XX and 39,XO mice with the aim of identifying which genes are expressed from both X chromosomes as well as those genes deregulated in X chromosome monosomy. Keywords: Expression profiling by array For each tissue, the RNA samples of seven 40,XX, eight 39,XpO and eight 39,XmO mice were pooled by genotype into 9 groups, representing 3 biological replicates per genotype, as follows: 39,XpO-1 and 39,XpO-2 (3 pooled individuals each), 39,XpO-3 (2 pooled individuals); 39,XmO-1 and 39,XmO-2 (3 pooled individuals each), 39,XmO-3 (2 pooled individuals); 40,XX-1 and 40,XX-2 (3 pooled individuals each) 40,XX-3 (2 pooled individuals)

Project description: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.

Project description:Major complications with in vitro culture of female embryonic stem cells (ESC) have impeded study of sex-specific pluripotency; however, from the published work female pluripotency significantly differs to male. We report a replenishable female ESC system that has enabled us to optimise a protocol for preserving the XX karyotype. Our protocol also improves male ESC fitness. To demonstrate the utility of the system, we screened for regulators of the female-specific process of X chromosome inactivation, revealing a new role for chromatin remodellers Smarcc1 and Smarca4 in establishment of X inactivation. The remodellers create a nucleosome depleted region at gene promotors on the inactive X during exit from pluripotency, without which gene silencing fails. Our female ESC system provides a tractable model for XX ESC culture that will expedite study of female pluripotency and has enabled us to discover new features of the female-specific process of X inactivation. This experiment is designed to test the effect of our improved ES culture conditions on the male ES cell karyotype.
