Abstract

Myeloid and lymphoid neoplasm associated with FGFR1 is an aggressive disease, and resistant to all the current chemotherapies. To define the molecular etiology of this disease, we have developed murine models of this disease, in syngeneic hosts as well as in nonobese diabetic/severe combined immunodeficiency/interleukin 2Rγnull mice engrafted with transformed human CD341 hematopoietic stem/progenitor cells. Both murine models mimic the human disease with splenohepatomegaly, hypercellular bone marrow, and myeloproliferative neoplasms that progresses to acute myeloid leukemia. Molecular genetic analyses of these model mice, as well as primary human disease, demonstrated that CNTRL-FGFR1, through abnormal activation of several signaling pathways related to development and differentiation of both myeloid and T-lymphoid cells, contribute to overt leukemogenesis. Clonal evolution analysis indicates that myeloid related neoplasms arise from common myeloid precursor cells that retain potential for T-lymphoid differentiation. These data indicate that simultaneously targeting these pathways is essential to successfully treating this almost invariably lethal disease.
