(Submitter supplied) Polycomb repressive complexes (PRCs) play key roles in developmental epigenetic regulation. Yet the mechanisms that target PRCs to specific loci in mammalian cells remain incompletely understood. In this study, we show that Bmi1, a core component of Polycomb Repressive Complex 1 (PRC1), binds directly to the Runx1/CBFbeta transcription factor complex. Genome-wide studies in megakaryocytic cells demonstrate considerable chromatin occupancy overlap between the PRC1 core component Ring1b and Runx1/CBFbeta and functional regulation of a significant fraction of commonly bound genes. more...

(Submitter supplied) Native ChIP on chip for H3K27me3 in murine ES cells comparing WT and Ring1B-/- cells. Paper Abstract: How polycomb group proteins repress gene expression in vivo is not known. Whilst histone modifying activities of the polycomb repressive complexes have been studied extensively, in vitro data has suggested a direct activity of the PRC1 complex in compacting chromatin. Here, we investigate higher-order chromatin compaction of polycomb targets in vivo. more...

(Submitter supplied) The essential histone variant H2A.Z localises to both active and silent chromatin sites. In embryonic stem cells (ESCs), H2A.Z is also reported to co-localise with polycomb repressive complex 2 (PRC2) at developmentally silenced genes. The mechanism of H2A.Z targeting is not clear, but a role for the PRC2 component Suz12 has been suggested. Given this association, we wished to determine if polycomb functionally directs H2A.Z incorporation in ESCs. more...

(Submitter supplied) Polycomb repressor complexes (PRCs) are important chromatin modifiers fundamentally implicated in pluripotency and cancer. Polycomb silencing in embryonic stem cells (ESCs) can be accompanied by active chromatin and primed RNA polymerase II (RNAPII), but the relationship between PRCs and RNAPII remains unclear at the genome-wide level. We mapped PRC repression markers and four RNAPII states in ESCs using ChIP-seq, and found that PRC-targets exhibit a range of RNAPII variants. more...

(Submitter supplied) The established hierarchical model explaining co-occupancy of Polycomb repressor complexes 1 and 2 (PRC 1 and 2) at target loci proposes that the chromodomain of the polycomb protein, a core PRC1 subunit, recognises the H3K27me3 histone modification catalysed by PRC2. We used chromatin immunoprecipitation to analyse PRC1 occupancy at target loci in Eed-/- mouse embryonic stem cells (ESCs) that lack H3K27me3. more...

(Submitter supplied) We demonstrate that CBFb-SMMHCmaintains leukemia viability by inhibiting RUNX1 repression of MYC expression. Upon pharmacologic inhibition of CBF-SMMHC/RUNX1 binding, RUNX1 increases its association with three MYC distal downstream enhancers and represses MYC expression.

(Submitter supplied) We recently reported the discovery of a small molecule inhibitor, AI-10-49 which can specially inhibit the protein-protein interaction between RUNX1 tumor suppressor and CBFβ-SMMHC oncogene. We also demonstrated that AI-10-49 can re-establish the RUNX1 transcriptional program in inv(16) cells and can extend the survival of inv(16) leukemic mice. To identify the changes in chromatin accessibility associated with AI-10-49, we performed ATAC-seq analysis in ME-1 cells [human inv(16) leukemia cell line] treated with AI-10-49.

We also demonstrated that AI-10-49 can re-establish the RUNX1 transcriptional program in inv(16) cells and can extend the survival of inv(16) leukemic mice. To identify the epigenetic changes as well as RUNX1 binding associated with AI-10-49, we performed genome wide analysis of H3K27ac histone mark as well as RUNX1 bindings in ME-1 cells [human inv(16) leukemia cell line] treated with AI-10-49.

(Submitter supplied) Polycomb activity is frequently altered in acute leukaemia through mutation or deletion of Polycomb Repressive Complex (PRC) components. Alterations in PRC-interacting factors such as the Core Binding Factor (CBF) complex should also affect leukemia biology, even if PRC composition is normal. We report that the acute myeloid leukemia (AML)-associated CBFβ-SMMHC fusion oncoprotein physically interacts with the PRC1 complex, and that these factors co-localize across the AML genome in a PRC2-independent manner. more...

(Submitter supplied) ChIP-seq for H3K27me3 and Ring1B was performed in WT mESCs and mESCs containing catalytically inactive Ring1B (I53A mutant). Cells expressing catalytically inactive Ring1B maintain the spatial distribution of Ring1B and H3K27me3 but at reduced levels. These findings support the notion that PRC2 recruitment is, in part, dependent on H2A ubiquitination (H2AK119ub).
