Title | Abstract |
| The kinase inhibitor TKI258 is active against the novel CUX1-FGFR1 fusion detected in a patient with T-lymphoblastic leukemia/lymphoma and t(7;8)(q22;p11). | We report a patient with T-lymphoblastic leukemia/lymphoma and a t(7;8)(q22;p11). CUX1 was identified as the fusion partner of FGFR1 by fluorescence in situ hybridization and 5 RACE-PCR. We further investigated this novel FGFR1 fusion using the interleukin-3 (IL-3) dependent Ba/F3 cell line and demonstrated IL-3 independent cell growth of CUX1-FGFR1 expressing cells. TKI258 and PKC412 potently inhibited proliferation of CUX1-FGFR1 transformed Ba/F3 cells. This growth inhibition was shown to be mediated by inhibition of CUX1-FGFR1 kinase activity for TKI258 but not PKC412. In summary, we identified a novel CUX1-FGFR1 fusion oncogene in a patient with the 8p11 myeloproliferative syndrome and demonstrated its transforming potential in the Ba/F3 cell line. Our in vitro data support the further investigation of TKI258 for the treatment of constitutively active FGFR1 fusion proteins. |
