Project description:Background: MLL (KMT2A)-EB1 (MAPRE1) fusion was identified in a patient with de novo pro-B acute lymphoblastic leukemia. To investigate the leukemogenesis of MLL-EB1 fusion, a retroviral transduction of MLL-EB1 to murine bone marrow cells was performed. A frequent MLL fusion, MLL-AF10(OM-LZ), was used as a positive control. Results: Two MLL-EB1 immortalized cell lines (ME1 and ME2G), and a MLL-AF10(OM-LZ) immortalized cell line (12G) were generated. Microarray results showed that many genes including Evi1 and Ets1 were differentially expressed in ME1/ME2G and 12G cell lines.

Project description:The t(10;11) p (13;q14) translocation, giving rise to CALM-AF10, is a recurring chromosomal translocation observed in several types of acute leukemias as well as in lymphoma. We have previously demonstrated that the expression of the human CALM/AF10 fusion gene in murine bone marrow stem and progenitor cells results in an aggressive acute myeloid leukemia in vivo. In this study, we have screened the various domains essential for CALM-AF10 function and leukemogenicity. Our study identifies a mutant of CALM-AF10 that greatly enhances the clonogenic potential of hematopoietic progenitors while retaining key characteristics of disease induced by the full length CALM-AF10 fusion. Global micro-RNA expression of bone marrow cells transduced with various constructs were compared. We used the empty vector, MIG, as a control and baseline. Four samples are tested with three biological replicates each.

Project description:The translocation t(10,11)(p13;q14) resulting in the formation of the CALM/AF10 fusion gene is involved in various hematological malignancies including acute myeloid leukemia, T-cell acute lymphoblastic leukemia, and malignant lymphoma and is usually associated with poor prognosis. We established a knock-in mouse model allowing tissue-specific CALM/AF10 expression from the Rosa26 locus using a loxP-STOP-loxP cassette to study leukemic transformation by the CALM/AF10 fusion protein during hematopoiesis. vav-Cre induced pan-hematopoietic expression of the CALM/AF10 fusion gene led to acute leukemia with a median latency of 12 months. Leukemias were either myeloid or had myeloid feature and showed expression of the B cell marker B220. Gene expression profiling of leukemic bone marrow cells revealed the overexpression of Hoxa cluster genes and the Hox co-factor Meis1. The long latency to leukemia development suggested that additional, collaborative genetic lesions are required. We identified an average of 2 to 3 additional mutations per leukemia using whole-exome sequencing. When CALM/AF10 was expressed in the B lymphoid compartment using mb1-Cre or CD19-Cre inducer lines no leukemia development was observed. Our results indicate that CALM/AF10 needs to be expressed from the stem or early progenitor cell stage onward to permit the acquisition of additional mutations required for leukemic transformation.

Project description:We have compared the gene expression profiles of leukemic tissues in two different mouse models of AML, CALM-AF10 and NHD13, to clincally healthy transgenic and wildtype hematopoetic tissue to identify genes and pathways that can collaborate with these oncogenic fusion proteins to promote leukemic transformation. CA10 and NHD13 transgenic mice were sacrificed when clinical signs of leukemia manifested (mice were hunched, skinny, or had an abnormal complete blood count). For comparsion, we harvested age matched bone marrow, thymi, and spleen from wildtype and clinically healthy trangenic tissues. Transgenic animals were considered clinically healthy if no evident signs of leukemia were present.
