Title:

Tumour cell responses to new fibroblast growth factor receptor tyrosine kinase inhibitors and identification of a gatekeeper mutation in FGFR3 as a mechanism of acquired resistance

Excerpt:
...FGFR3 protein levels were high in 97–7 cells, moderate in RT4 and RT112 cells, and low in 97–29 and T24 cells (Figure 2a); of these, 97–7 and 97–29 cells express FGFR3S249C….Both AZ8010 and AZD4547 inhibited the proliferation of 97–7 and RT4 cells (Figures 2b and c). The 97–7 and RT4 cells responded to AZD4547 with a dose-dependent G1 cell cycle arrest with no evidence of cell death (Figure 2d).
