Based on our previous data illustrating the functional connection between KIT inhibition and the activation of the FGF/FGFR pathway in GIST, we also cultured GIST T-1 cells with low concentrations of IM (0.02 μM) and also detected the increased expression of VEGF-A (Figure 2A—left panel). Here, VEGFA is linked to gastrointestinal stromal tumor.
