Expression data from ZMYM2-FGFR1-induced T-cell lymphomas in a mouse model
Ontology highlight
ABSTRACT: The ZMYM2-FGFR1 (formerly known as ZNF198-FGFR1) fusion kinase induces stem cell leukemia-lymphoma syndrome (SCLL), a hematological malignancy characterized by rapid transformation to acute myeloid leukemia and T-lymphoblastic lymphoma. We previously developed a mouse model of ZMYM2-FGFR1 (Ren et al. 2009, Blood). To further investigate mechanisms of oncogenesis and progression, we undertook a global gene expression analysis of leukemic T-cells from the animal model compared with Thy1+DP+ (CD4+CD8+) cells isolated from normal Balb/c thymuses, as well as lukemic stem cells (LSK, GFP+Lin-Sca-1+c-kit+ cells) sorted from the leukemic mice versus hematopoietic stem cells (HSC, Lin-Sca-1+c-kit+ cells) sorted from normal BALB/c bone marrow cells. We found high expressions of Notch1 and its downstream target genes in T-cell lymphomas that arise in a murine model of ZMYM2-FGFR1 SCLL. Our functional studies demonstrate the importance of Notch signaling in the etiology of SCLL and suggest that targeting this pathway could provide a novel strategy for molecular therapies to treat SCLL patients.
