(Submitter supplied) MDA-MB-231 cell line with relatively high DOT1L levels was treated with two potent, selective inhibitors of the DOT1L histone methyl transferase. These compounds can inhibit cells migration and invasion and induce differentiation. Here we provide expression profiling data of cells treated with two DOT1L inhibitors [1] [2], DOT1L siRNA (siDOT1L) or control.

(Submitter supplied) The MLL gene on chromosome 11 fuses to the AF6 gene on chromosome 6 in a balanced chromosomal translocation that is characetristic of certain adult and pediatric human leukemias. We established a murine leukemia model of MLL-AF6 using the retroviral MLL-AF6 contruct in a bone marrow transplantation system. The ML2 human MLL-AF6 positive leukemia cell line was used for gene expression profiling to assess the transctiptional profile in MLL-AF6 leukemias.

(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) Cell lines bearing MLL translocations (MV4-11 and MOLM-13) were treated with a potent, selective inhibitor of the DOT1L histone methyl transferase. Treatment of MLL-rearranged cell lines with the DOT1L inhibitor selectively inhibits H3K79 methylation and blocks expression of leukemogenic genes. Here we provide expression profiling data of cells treated with DOT1L inhibitor or vehicle control.

Temporal analysis of mixed lineage leukemia (MLL)-rearranged cell lines MV4-11 and MOLM-13 treated with EPZ004777, a potent inhibitor of DOT1L histone methyl transferase. EPZ004777 induces differentiation and apoptosis in MLL-rearranged cells. Results provide insight into role of DOT1L in MLL cells.

(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) 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...

Immunophenotypic and gene expression analysis of the ALL cells demonstrated bone marrow replacement with B-precursor cells which express a gene expression profile that has significant overlap with profiles in human MLL-rearranged ALL. more...

(Submitter supplied) We created a mouse model where conditional expression of physiologic levels of an Mll-AF4 fusion oncogene induces development of acute lymphoblastic (ALL) or acute myeloid leukemias (AML). ChIP-chip analysis demonstrated increased histone H3 Lysine 79 (H3K79) dimethylation that correlated with Mll-AF4 associated gene expression profiles in murine ALLs, and in human MLL-rearranged leukemias. In addition, human MLL-rearranged ALLs can be distinguished from other ALLs by their genome-wide H3K79 methylation profiles. more...
