(Submitter supplied) 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). more...

(Submitter supplied) OBJECTIVE: MEIS1, a HOX cofactor, collaborates with multiple HOX proteins, such as HOXA9, to accelerate the onset of acute myeloid leukemia (AML) through largely unknown molecular mechanisms. To further resolve these mechanisms, we conducted a structure-function analysis of Meis1 and gene expression profiling, in the context of Hoxa9 leukemogenesis. RESULTS: We show, in a murine bone marrow transplantation model, that the homeodomain of Meis1 is required for leukemogenic collaboration with Hoxa9. more...

(Submitter supplied) Aberrant expression of homeobox transcription factor HOXA9 is a central component of the leukemogenic program driven by diverse oncogenes. Here we show that HOXA9 overexpression in myeloid progenitor cells and pro-B cells leads to significant rearrangement of the epigenetic landscape with prominent emergence of cancer specific de novo enhancers. HOXA9 acts as a pioneer factor at the de novo enhancers and is required for recruitment of transcription factor CEBP/a and the histone H3K4 methyltransferase MLL3/MLL4 complex. more...

(Submitter supplied) Leukemia is caused by the accumulation of multiple genomic lesions in hematopoietic precursor cells. However, how these events cooperate during oncogenic transformation remains poorly understood. We studied the cooperation between activated JAK3/STAT5 signaling and HOXA9 overexpression, two events identified as significantly co-occuring in T-cell acute lymphoblastic leukemia. Expression of mutant JAK3 and HOXA9 led to a rapid development of leukemia originating from multipotent or lymphoid-committed progenitors, with a significant decrease in disease latency compared to JAK3 or HOXA9 alone. more...

(Submitter supplied) Purpose: To characterize transcriptional changes associated with homozygous inactivation of Dot1l or Mll1 in MN1 driven AML Methods: We sequenced mRNA from murine LSK-cells transformed using forced expression of MN1 (MSCV-MN1-IRES-GFP), and transduced with Cre-vector to inactivate either Dot1l or Mll1. Cells were sorted for Cre-expression (pTomato fluorescent marker) or expression of an inert control vector. more...
