Gene expression changes upon Mof knockout in MLL-AF9 transformed murine LSKs

Project description:We report Illumina next generation RNA sequencing (RNAseq) of MLL-AF9 in vitro transformed murine LSKs upon genetic deletion of Mof. These gene expression data illustrate that Mof regulates the expression of genes involved in DNA damage response and chromatin stability in MLL-AF9 transformed cells.

Chromatin state changes induced by targeted degradation of MLL-AF9 are phenocopied by combined DOT1L and MENIN inhibition. [RNA-Seq]

Project description:Using RNA-seq we examined the transcriptional changes following MLL-AF9 degradation in MLL-AF9-HA-FKPB12 transformed murine (BM2222) and human (HCB1) cells. We also examined transcriptional changes in human MLL-AF9-HA-FKBP12 transformed cells (HCB1) and MOLM13 cells in response to DOT1L inhibition, Menin-MLL inhibition, and the combination of DOT1L and Menin-MLL inhibition. Lastly we assessed gene expression in murine neutrophils isolated directly from mice.

Mll-AF9 induced changes in gene expression in various hematopoietic cells

Project description:The pathways by which oncogenes, such as MLL-AF9, initiate transformation and leukemia in humans and mice are incompletely defined. In a study of target cells and oncogene dosage, we found that Mll-AF9, when under endogenous regulatory control, efficiently transformed LSK (Lin- Sca1+ c-kit+) stem cells while committed granulocyte-monocyte progenitors (GMPs) were transformation-resistant and did not cause leukemia. Mll-AF9 was expressed at higher levels in hematopoietic stem (HSC) than GMP cells. Mll- AF9 gene dosage effects were directly shown in experiments where GMPs were efficiently transformed by the high dosage of Mll-AF9 resulting from retroviral transduction. Mll-AF9 up-regulated expression of 196 genes in both LSK and progenitor cells, but to higher levels in LSKs than in committed myeloid progenitors. Keywords: mutant hematopoietic cells

Chromatin state changes induced by targeted degradation of MLL-AF9 are phenocopied by combined DOT1L and MENIN inhibition. [ChIP-Seq]

Project description:Using ChIP-seq we examined the occupancy changes of various histone marks and chromatin-bound proteins following accute MLL-AF9 degradation in MLL-AF9-HA-FKPB12 transformed human (HCB1) cells. We also examined occupancy changes of various chromatin-bound proteins in human MLL-AF9-HA-FKBP12 transformed cells (HCB1) and MOLM13 cells in response to DOT1L inhibition, Menin-MLL inhibition, and the combination of DOT1L and Menin-MLL inhibition.

PRC2 is required for acute myeloid leukemias initiated by MLL-AF9

Project description:The transcriptional activating and repressive functions performed by Trithorax and Polycomb group complexes, respectively, are critical for to maintain cellular fates in ontogeny and in cancer. Here we report that leukemias initiated by a Trithorax-related oncogene, MLL-AF9, depend upon the Polycomb Repressive Complex 2 (PRC2) to sustain a transformed cellular state. RNAi mediated suppression of PRC2 subunits is sufficient to inhibit proliferation of MLL-AF9 leukemias, with little impact on growth of non-transformed cells. This requirement is partly due to PRC2-mediated transcriptional repression of several anti-self-renewal regulators, including Cdkn2a. These results suggest that, unlike the classical antagonism generally observed between Polycomb and Trithorax group proteins during development, the activities of these two pathways can cooperate to promote myeloid neoplasia. In order to understand downstream targets of PRC2 complex in MLL-AF9 leukemia, we performed array in murine MLL-AF9/NrasG12D cell line under the condition that two subunits of PRC2(Eed and Suz12) were suppressed by using shRNAs.

H3K9me3 ChIP-seq in MLL-rearranged leukemic stem cells and hematopoietic stem cells

Project description:Acute myeloid leukemia (AML) with rearrangement of the mixed-lineage leukemia (MLL) gene are the most aggressive hematopoietic malignancies. Previous studies demonstrated the distribution of several epigenetic modifications including H3K9me3, H3K79me2, H3K36me3, H3K4me3 and H3K27me3, in MLL-AF9 transformed murine cells. Here, we examined the H3K9me3 distribution in c-Kit+ cells (enriched with stem/progenitor cells) from both MLL-AF9 transformed murine cells in parallel with control wild-type cells, and found an overall lower distribution of H3K9me3 in leukemia stem cells than normal hematopoietic stem/progenitor cells.
