Project description:Congenital heart disease is among the most frequent major birth defects. Epigenetic marks are crucial for organogenesis, but their role in heart development is poorly understood. Polycomb Repressive Complex 2 (PRC2) trimethylates histone H3 at lysine 27, establishing H3K27me3 repressive epigenetic marks that promote tissue-specific differentiation by silencing ectopic gene programs. We studied the function of the catalytic subunit of PRC2, EZH2, in murine heart development. Early EZH2 inactivation by Nkx2-5Cre caused lethal congenital heart malformations, but slightly later EZH2 inactivation by cTNT-Cre did not. To study how the cardiomyocytes gene expression program is properly established in the early heart development, we combined the technologies of RNA sequencing and chromatin immunoprecipitation sequencing to identify the functional target genes directly repressed by EZH2. Intriguingly, these were enriched for transcriptional regulators of non-cardiac expression programs, such as transcription factors that regulate neuronal (Pax6) and cardiac progenitor genes (Isl1 and Six1). EZH2 was also required to maintain spatiotemporal regulation of cardiac gene expression, as Hcn4, Mlc2a, and Bmp10 were inappropriately upregulated in ventricular RNA. Furthermore, EZH2 was required for normal cardiomyocyte proliferation, establishing H3K27me3 epigenetic marks at cell cycle inhibitors Ink4a/b and repressing their expression. Our study reveals a previously undescribed role of EZH2 in regulating heart formation and shows that perturbation of the epigenetic landscape early cardiogenesis has sustained disruptive effects at later developmental stages. 8 E12.5 heart apex were used for RNA preparation each group.

Project description:RNA-seq for DKO, E1KO, E2KO and WT E12.5 heart revealed that EZH1 and EZH2 play a partially redundant role to trimethylate histone H3 at Lys 27 (H3K27me3). Through EZH1, H3K27me3 and H3K27ac ChIP-seq and RNA-seq for P13 EZH1 and GFP overexpressing heart (AAVEzh1 and AAVGFP respectively) suffered MI at P10, we surprisingly found that EZH1 can active the expression of regenerating relevant genes by directly binding to the promoter of targeted genes and through a mechanism independent of H3K27me3 deposition. Together, we unravel a requirement but divergent mechanisms of EZH1 in heart development and regeneration

Project description:Gene expression (RNA-seq) and H3K27me3 binding (ChIP-seq) profiling of wild type and Ezh2-deficient mouse lung epithelium. Lungs from wild type and Ezh2-deficient mice (Ezh2 deletion is specific to lung epithelium) were collected at day e16.5. Lung cells were separated into epithelial and stromal populations based on EpCAM expression. Epithelial cells were profiled for both gene expression (Total RNA-seq) and H3K27me3 binding (ChIP-seq). Additionally, stromal cells were also profiled for gene expression.

Project description:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.
