Project description:Enhancers play a central role in cell-type-specific gene expression and are marked by H3K4me1/2. Active enhancers are further marked by H3K27ac. However, the methyltransferases responsible for the deposition of H3K4me1/2 on enhancers remain elusive. Furthermore, the functions of these methyltransferases on enhancers and associated cell-type-specific gene expression are poorly understood. Here, we identify MLL4 (KMT2D) as a major H3K4 mono- and di-methyltransferase in mammalian cells. Using adipogenesis and myogenesis as model systems, we show that MLL4 exhibits cell-type- and differentiation-stage-specific genomic binding and is predominantly localized on enhancers. MLL4 co-localizes with lineage-determining transcription factors (TFs) on active enhancers during differentiation. Deletion of MLL4 dramatically decreases H3K4me1/2 and H3K27ac on enhancers and leads to severe defects in cell-type-specific gene expression and cell differentiation. Finally, we provide evidence that lineage-determining TFs recruit and require MLL4 to establish enhancers critical for cell-type-specific gene expression. Together, these results identify MLL4 as an H3K4 mono-/di-methyltransferase required for enhancer activation during cell differentiation. ChIP-Seq of MyoD, MLL4 and histone modifications (H3K4me1, H3K4me3, and H3K27ac) in adenoviral GFP- or Cre-infected MLL3-/-;MLL4-flox/flox cells. Preadipocytes: brown preadipocytes before differentiation. D5 myocytes: 5 days after MyoD-induced myogenesis of brown preadipocytes.

Project description:We performed ChIP-seq to chart genome-wide maps of H3K27me3 in brown preadipocytes and mature brown adipocytes. We observed a subset of brown fat-specific genes, but not common fat genes or white fat-specific genes, possess the H3K27me3 mark in preadipocytes, and this mark is erased in mature adipocytes. H3K27me3 ChIP-seq in brown preadipocytes and mature adipocytes.
