PBX3 cooperates with MEISI in causing rapid acute myeloid leukemia and recapitulates the core transcriptome of MLL-rearranged leukemia

Project description:To investigate whether co-expression of PBX3/MEIS1 can mimic that of MLL-AF9, HOXA9/MEIS1 or HOXA9/PBX3 in inducing leukemogenesis, we conducted in vivo mouse bone marrow transplantation (BMT) assays. Briefly, normal mouse bone marrow (BM) progenitor (i.e., lineage negative; Lin-) cells collected from B6.SJL (CD45.1) donor mice (CD45.1) were retrovirally co-transduced with MSCVneo-MLL-AF9+MSCV-PIG (MLL-AF9), MSCVneo-HOXA9+MSCV-PIG (HOXA9), MSCVneo-HOXA9+MSCV-PIG-MEIS1 (HOXA9+MEIS1), MSCVneo-HOXA9+MSCV-PIG-PBX3 (HOXA9+PBX3), MSCV-PIG-PBX3+MSCVneo-MEIS1 (PBX3+MEIS1), MSCVneo+MSCV-PIG-PBX3 (PBX3) , MSCVneo+MSCV-PIG-MEIS1 (MEIS1), or MSCVneo+MSCV-PIG (normal control; NC). Retrovirally transduced cells then were cultured with cytokines as well as puromycin and G418. Seven days later, the donor cells were transplanted into lethally irradiated (960 rads) 8- to 10-week-old C57BL/6 (CD45.2) recipient mice. The transplanted mice were watched for leukemogenesis. Then, gene expression profiling was conducted with bone marrow samples collected from leukemia groups and control group.

PML-RARA fusion gene requires Dnmt3a to induce acute promyelocytic leukemia in mice

Project description:Loss of function mutations in the DNA methyltransferase DNMT3A are highly recurrent in acute myeloid leukemia (AML). DNMT3A and DNMT3B encode the two methyltransferases that are primarily responsible for the de novo methylation of specific DNA sequences during cellular differentiation. DNMT3A mutations are rarely found in AML patients with translocations that create oncogenic fusion genes (e.g. PML-RARA, RUNX1-RUNX1T1, CBFB-MYH11, and MLL-X). To begin to define the reasons why these mutations do not occur together, we used retroviral vectors to express PML-RARA, RUNX1-RUNX1T1, and MLL-AF9 in the bone marrow cells of wild type (WT) or Dnmt3a deficient mice; we also examined the hematopoietic phenotypes of Ctsg-PML-RARA animals (which express PML-RARA in early hematopoietic progenitors and myeloid precursors) with and without Dnmt3a. We demonstrated that the methyltransferase activity of Dnmt3a (but not Dnmt3b) is required for aberrant self-renewal ex vivo that is driven by PML-RARA (but not RUNX1-RUNX1T1 or MLL-AF9); furthermore, the PML-RARA-driven competitive transplantation advantage and leukemia generation both required Dnmt3a. Together, these findings demonstrate that PML-RARA is specifically dependent on Dnmt3a to initiate APL in mice, and may explain why loss-of-function DNMT3A mutations are not found in patients with acute promyelocytic leukemia.

PML-RARa induces dynamic changes in genome architecture during leukemic transformation

Project description:Acute Promyelocytic Leukemia (APL) is a fatal subtype of leukemia driven by the translocation between genes encoding the Promyelocytic Leukemia (PML) protein and the Retinoic Acid Receptor alpha (RARa) protein. We use mouse hematopoietic progenitor cells expressing PML-RARa and dissect the dynamic changes in the epigenome, transcriptome and genome architecture triggered by the expression of this oncogenic transcription factor during leukemic transformation. We find that PML-RARa induces a continuum of topologic and transcriptional alterations, mostly affecting distal regulatory elements. Furthermore, we identify Klf4 ― a master regulator of hematopoietic differentiation ― as an early mis-regulated gene during leukemogenesis, and deconstruct the dynamic alterations in long-range interactions, histone modifications and transcriptional output triggered by PML-RARa expression at the Klf4 locus. Our study provides a comprehensive overview of the dynamic genomic and transcriptomic alterations induced by PML-RARa, which ultimately block hematopoietic differentiation and induce leukemic transformation.
