Summary
Wang et al. (2017) conducted a functional genetic screen in FGFR-mutant urothelial carcinoma cells to identify mechanisms of resistance to FGFR inhibitors. The screen identified the phosphoinositide 3-kinase signalling pathway as a critical determinant of resistance, suggesting that dual inhibition of FGFR and PI3K pathways might enhance therapeutic efficacy. This work contributes to understanding tumour adaptation mechanisms and potential strategies to overcome drug resistance in this cancer type.
UK applicability
This laboratory study on cancer cell resistance mechanisms has limited direct application to UK farming systems or soil health. However, findings on therapeutic resistance may inform oncology treatment strategies in UK clinical practice for patients with FGFR-driven urothelial cancers.
Key measures
Pathway components and genes associated with FGFR inhibitor resistance; phosphoinositide 3-kinase pathway activity as a resistance mechanism
Outcomes reported
The study employed functional genetic screening to identify signalling pathways conferring resistance to FGFR inhibitors in FGFR-mutant urothelial cancer cells. As suggested by the title, the phosphoinositide 3-kinase pathway emerged as a key determinant of treatment resistance.
