Expression profiling of primary wild type (WT), Ezh2-null and Eed-null murine MLL-AF9 AML

Project description:We evaluated gene expression changes in murine leukemia caused by retroviral overexpression of MLL-AF9. We compared wild-type (WT) leukemia cells with mutant leukemia cells after cre-mediated inactivation of homozygous conditional alleles for Ezh2 or Eed, both of which are components of the Polycomb Repressive Complex2. For WT cells, 3 biological replicates were hybridized. For Ezh2-null cells, 4 biological replicates were hybridized. For Eed-cells, 3 biological replicates were hybridized.

Expression profiling of secondary wild type (WT) and Ezh2-null murine MLL-AF9 AML

Project description:We evaluated gene expression changes in secondary recipient murine leukemia caused by retroviral overexpression of MLL-AF9. We compared wild-type (WT) leukemia cells with mutant leukemia cells after cre-mediated inactivation of a homozygous conditional allele for Ezh2, a component of the Polycomb Repressive Complex2. For WT cells, 4 biological replicates were hybridized. For Ezh2-null cells, 5 biological replicates were hybridized.

Epigenetic profiling of WT and Ezh2-null MLL-AF9 murine leukemic cells

Project description:Chromatin immunoprecipitation (ChIP) for H3K27me3 followed by Solexa sequencing in WT and Ezh2-null leukemic cells from primary and secondary recipients. Leukemic cells from primary and secondary recipients of MLL-AF9-transduced WT and Ezh2-null cells were sorted for GFP and YFP expression and analyzed by Chip-Seq.

Hes1 is responsible for Notch signaling-mediated suppression of acute myeloid leukemia development

Project description:In leukemogenesis Notch signaling can be up- and down-regulated in a context-dependent manner. Here we report that deletion of hairy and enhancer of split-1 (Hes1) promotes acute myeloid leukemia (AML) development induced by the MLL-AF9 fusion protein. Subsequently, the FMS-like tyrosine kinase 3 (FLT3) was up-regulated in mouse cells of a Hes1- or RBP-J-null background. MLL-AF9-expressing Hes1-null AML cells showed enhanced proliferation and ERK phosphorylation following FLT3 ligand stimulation. FLT3 inhibition efficiently abrogated proliferation of MLL-AF9-induced Hes1-null AML cells. Furthermore, an agonistic anti-Notch2 antibody induced apoptosis of MLL-AF9-induced AML cells in a Hes1-wild type but not a Hes1-null background. These observations demonstrate that Hes1 mediates tumor suppressive roles of Notch signaling in AML development by down-regulating FLT3 expression. 4 samples are analyzed, two pairs of MLL-AF9/Hes1-/- and MLL-AF9/Hes1+/+ leukemic bone marrows.
