Identification of cooperative genes for NUP98-HOXA9 in myeloid leukemogenesis using a mouse model..     ///    These genes cooperated with NUP98-HOXA9 in transforming NIH 3T3 cells.     ///    "This suggested that the NUP98-HOXA9 fusion induced a preleukemic phase, and other factors were required for complete leukemogenesis. "    ///    We generated a transgenic mouse line that specifically expressed the chimeric NUP98-HOXA9 gene in the myeloid lineage.     ///    NUP98-HOXA9 expression promoted the onset of retrovirus-induced BXH2 myeloid leukemia.
