(Submitter supplied) Methylation of H3K79 is associated with chromatin at expressed genes, though it is unclear if this histone modification is required for transcription of all genes. Recent studies suggest that Wnt-responsive genes depend particularly on H3K79 methylation, which is catalyzed by the methyltransferase DOT1L. Human leukemias carrying MLL gene rearrangements show DOT1L-mediated H3K79 methylation and aberrant expression of leukemogenic genes. more...

(Submitter supplied) Background: Wnt signaling maintains the undifferentiated state of intestinal crypt progenitor cells by inducing the formation of nuclear TCF4/beta-catenin complexes. In colorectal cancer, activating mutations in Wnt pathway components cause inappropriate activation of TCF4/beta-catenin-driven transcription. Despite the passage of a decade after the discovery of TCF4 and beta-catenin as the molecular effectors of the Wnt signal, few transcriptional activators essential and unique to the regulation of this transcription program have been found. more...

(Submitter supplied) DOT1L as methyltransferase of H3K79 is implicated in brian development. Here, we further defined DOT1L function within the granular neurons during cerebellar development using ChIP-seq of H3K79 dimethylation of isolated cerebellar granular neurons and progenitors. Thereby we compared samples treated with a DOT1L inhibitor versus DMSO treated cells. The data sets reveals new important targets of DOT1L, which ensure a correct development of the cerebellum.

(Submitter supplied) DOT1L as methyltransferase of H3K79 is implicated in brian development. Here, we further defined DOT1L function in gene expression during cerebellar development using Microarrays. For that we generated Dot1l knockout mice using a Atoh-Cre driver line resulting in a Dot1l knockout within the cerebellum. The RNA of cerebellar tissue of the Dot1l knockout animals was thereby compared to controls. Additionally we compared the RNA levels of cultured CGNP and CGN samples treated with a DOT1L inhibitor versus DMSO treated cells. more...

(Submitter supplied) Actively transcribed genes in mammals are decorated by H3K79 methylation, which is correlated with transcription levels and is catalyzed by the histone methyltransferase DOT1L. DOT1L is required for mammalian development, and the inhibition of its catalytic activity has been extensively studied for cancer therapy; however, the mechanisms underlying DOT1L’s functions in normal development and cancer pathogenesis remain elusive. more...

(Submitter supplied) Enhancer elements are a key regulatory feature of many important genes. Several general features including the presence of specific histone modifications are used to demarcate potentially active enhancers. Here we reveal that putative enhancers marked with H3 lysine 79 (K79) di or trimethylation (me2/3) (which we name H3K79me2/3 enhancer elements or KEEs) can be found in multiple cell types. Mixed lineage leukemia gene (MLL) rearrangements (MLL-r) such as MLL-AF4 are a major cause of incurable acute lymphoblastic leukemias (ALL). more...

(Submitter supplied) The histone 3 lysine 79 (H3K79) methyltransferase Dot1l has been implicated in the development of leukemias bearing translocations that involve the Mixed Lineage Leukemia (MLL) gene. We identified the MLL-fusion targets in a murine MLL-AF9 leukemia model, and conducted epigenetic profiling for H3K79me2, H3K4me3, H3K27me3 and H3K36me3. Histone methylation patterns are highly abnormal on MLL-AF9 fusion target loci, defining a distinct epigenetic lesion involving H3K79. more...
