Polycomb repressive complex 1 (PRC1) role in skin epithelium development [Epi Eed cKO]

Project description:Polycomb repressive complexes (PRC) 1 and 2 are essential chromatin regulators of cell identity. PRC1, a dominant executer of Polycomb-mediated control, functions as multiple sub-complexes that possess catalytic-dependent H2AK119 mono-ubiquitination (H2AK119ub) and catalytic-independent activities. Here, we show that despite its well-established repressor functions, PRC1 binds to both silent and active genes. Through in vivo loss-of-function studies, we show that global PRC1 function is essential for skin development and stem cell (SC) specification.

The Central Role of EED in the Orchestration of Polycomb Group Complexes

Project description:Polycomb Repressive Complexes 1 and 2 (PRC1 and 2) play a critical role in the epigenetic regulation of transcription during cellular differentiation, stem cell pluripotency, and neoplastic progression1-3. Here we show that the Polycomb group protein EED, a core component of PRC2, physically interacts with and functions as part of the PRC1 complex. Components of PRC1 and PRC2 compete for EED binding. EED functions to recruit PRC1 to H3K27me3 loci and enhances PRC1 mediated H2A ubiquitin E3 ligase activity. Taken together, we uncover the integral role of EED as an epigenetic exchange factor coordinating the activities of PRC1 and 2.

EED orchestration of heart maturation through interaction with HDACs is H3K27me3-independent

Project description:In proliferating cells, where most Polycomb repressive complex 2 (PRC2) studies have been performed, gene repression is associated with PRC2 trimethylation of H3K27 (H3K27me3). However, it is uncertain whether PCR2 writing of H3K27me3 is mechanistically required for gene silencing. Here we studied PRC2 function in postnatal mouse cardiomyocytes, where the paucity of cell division obviates bulk H3K27me3 rewriting after each cell cycle. EED (Embryonic Ectoderm Development) inactivation in the postnatal heart (Eed CKO ) caused lethal dilated cardiomyopathy. Surprisingly, gene upregulation in Eed CKO was not coupled with loss of H3K27me3. Rather, the activating histone mark H3K27ac increased. EED interacted with histone deacetylases (HDACs) and enhanced their catalytic activity. HDAC overexpression normalized Eed CKO heart function and expression of derepressed genes. Our results uncovered a non-canonical, H3K27me3-independent EED repressive mechanism that is essential for normal heart function. Our results further illustrate that organ dysfunction due to epigenetic dysregulation can be corrected by epigenetic rewiring.

Next-generation Sequencing Facilitates Quantitative Analysis of Wild Type and EED cKO mice Hippocampus Dentate Gyrus Transcriptomes

Project description:Purpose:Quantification differentially expressed genes and find target genes. The goals of this study are to compare Wild Type and EED cKO hippocampus dentate gyrus transcriptome profiling (RNA-seq) to quantitative reverse transcription polymerase chain reaction (qRT–PCR) differentially expressed genes and find target genes Methods: Hippocampus dentate gyrus mRNA profiles of 14-day-old wild-type (WT) and Embryonic Ectoderm Development conditional knockout (EED cKO) mice were generated by deep sequencing, in two biological replicates,using BGISEQ-500 platform.All RNA-Seq data were aligned to mouse genome version mm10 using HISAT.We use cluster software and Euclidean distance matrix for the hierarchical clustering analysis of the expressed gene and sample program at the same time, the clustering results can be viewed with javaTreeview. qRT–PCR validation was performed using SYBR Green assays. Results:Only transcripts that showed more than 2-fold differential expression compared to control were subjected to relevance network analysis. 1047 candidate genes that were differentially expressed with biological functional groups as compared between WT and EED cKO mice . Conclusions: Our study represents the first detailed analysis of Wild Type and EED cKO mice hippocampus dentate gyrus transcriptomes, with two biologic replicates, generated by RNA-seq technology.
