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. In the experiment, the researchers used many compounds, for example, 4-Amino-5-fluoro-3-(6-(4-methylpiperazin-1-yl)-1H-benzo[d]imidazol-2-yl)quinolin-2(1H)-one 2-hydroxypropanoate (cas: 692737-80-7HPLC of Formula: 692737-80-7).
4-Amino-5-fluoro-3-(6-(4-methylpiperazin-1-yl)-1H-benzo[d]imidazol-2-yl)quinolin-2(1H)-one 2-hydroxypropanoate (cas: 692737-80-7) belongs to piperazine derivatives. Piperazine causes primary dermal irritation and skin burns at high concentrations. Piperazine also causes eye irritation in humans. Piperazine is an anthelminthic especially useful in the treatment of partial intestinal obstruction caused by Ascaris worms, which is a condition primarily seen in children. Piperazine hydrate and piperazine citrate are the main anthelminthic piperazines.HPLC of Formula: 692737-80-7
