Project description:Mouse ES-cells with different sex chromosome compliment were differentiated into EpiSC, samples were taken every 4-12 hours for 84 hours in total. The original data for the XX-cells is also available as GSE34243, but normalisation of these differs.

Project description:Abdominal aortic aneurysms (AAAs) are a prevalent and deadly human pathology with strong sexual dimorphism. Research demonstrates that sex hormones influence, but do not fully explain, male versus female AAA pathology. In addition to sex hormones, the X and Y sex chromosomes, and their unique complements of genes, may contribute to sexually dimorphic AAA pathology. Here, for the first time, we defined the effect of female (XX) versus male (XY) chromosome complement on AAA formation and rupture in phenotypically female mice using an established murine model. Abdominal aortas from female mice bearing the XY chromosome selectively expressed Y chromosome genes, while genes known to escape X-inactivation were higher in XX females. The majority of gene differences in XY females fell within inflammatory pathways. When XY females were infused with AngII, AAA incidences doubled and aneurysms ruptured. AAAs from XY females exhibited significant inflammation. Moreover, infusion of AngII to XY females augmented aortic activity of matrix metalloproteinases. Finally, testosterone exposure applied chronically, or as a single bolus at postnatal day 1, markedly worsened AAA outcomes in XY compared to XX females. These results demonstrate that an XY sex chromosome complement profoundly influences aortic gene expression profiles and promotes AAA severity.

Project description:Major depressive disorder (MDD) is characterized by symptom heterogeneity and sex differences in prevalence. To gain insight into these sex differences, we utilized the subchronic variable stress paradigm (SCVS) in which female mice are susceptible, while males are behaviorally resilient. We used the Four Core Genotypes mice to differentiate between sex chromosome complement (XX vs. XY) and gonad type (ovaries vs. testes) in stress susceptibility, uncoupling these factors by removing the testes-determining SRY gene from the Y chromosome. Mice were subjected to SCVS followed by assays to assess anxiety-/depressive-like behaviors. Regardless of gonads, XX mice were stress susceptible, while XY mice were stress resilient, underscoring the importance of sex chromosome effects to sex differences in susceptibility to SCVS, independent of gonad type. We then performed RNA-sequencing of the prefrontal cortex (PFC) and nucleus accumbens (NAc). Consistent with human MDD and previous rodent SCVS findings, there was little overlap in genes altered by SCVS across sex. In stress susceptible XX mice, stress exposure altered pathways related to immune function, while in resilient XY mice, stress exposure altered pathways involved in neuronal function. There was brain region specificity to how sex chromosome complement and gonad type contributed to sex-specific stress effects. In the NAc, sex chromosome complement was the primary contributor to stress-induced gene expression, while in the PFC, both sex chromosome complement and gonad type contributed. These findings underscore a complex relationship between sex chromosome complement and gonadal factors in shaping stress vulnerability, partly through immune-related pathways.

Project description:Sex biases in the genome-wide distribution of DNA methylation and gene expression levels are some of the manifestations of sexual dimorphism in mammals. To advance our understanding of the mechanisms that contribute to sex biases in DNA methylation and gene expression, we conducted whole genome bisulfite sequencing (WGBS) as well as RNA-seq on liver samples from mice with different combinations of sex phenotype and sex-chromosome complement. We compared groups of animals with different sex phenotypes, but the same genetic sexes, and vice versa, same sex phenotypes, but different sex-chromosome complements. We also compared sex-biased DNA methylation in mouse and human livers. Our data show that sex phenotype, X-chromosome dosage, and the presence of Y chromosome shape the differences in DNA methylation between males and females. We also demonstrate that sex bias in autosomal methylation is associated with sex bias in gene expression, whereas X-chromosome dosage-dependent methylation differences are not, as expected for a dosage-compensation mechanism. Furthermore, we find partial conservation between the repertoires of mouse and human genes that are associated with sex-biased methylation, an indication that gene function is likely to be an important factor in this phenomenon.
