Project description:This SuperSeries is composed of the following subset Series: GSE34959: Expression profiling of primary wild type (WT), Ezh2-null and Eed-null murine MLL-AF9 AML GSE34961: Expression profiling of secondary wild type (WT) and Ezh2-null murine MLL-AF9 AML GSE34962: Epigenetic profiling of WT and Ezh2-null MLL-AF9 murine leukemic cells Refer to individual Series
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.
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.
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.
Project description:We used EZH2i-targeted hematological malignancies as an examples and focused on molecular characterization of EZH2 Y641 mutant hematological cell lines. We used the proteomic strategies and compared the protein expression level and lysine methylation level (including mono-, di-, and trimethylaiton) in EZH2 wild-type (EZH2 WT), EZH2 Y641N and Y641F (EZH2 MUT) cell lines.
