Frequent and Focal FGFR1 Amplification Associates with Therapeutically Tractable FGFR1 Dependency in Squamous Cell Lung Cancer

TL;DR: F focal FGFR1 amplification is common in squamous cell lung cancer and associated with tumor growth and survival, suggesting that FGFR inhibitors may be a viable therapeutic option in this cohort of patients.
Journal ArticleDOI

Identifying genotype-dependent efficacy of single and combined PI3K- and MAPK-pathway inhibition in cancer

TL;DR: By systematically linking drug response to genomic aberrations in non-small-cell lung cancer, as well as in cell lines of other tumor types and in a series of in vivo cancer models, it is shown that tumors with genetically activated receptor tyrosine kinases depend on PI3K signaling, whereas tumors with mutations in the RAS/RAF axis depend on MAPK signaling.
Journal ArticleDOI

Tumor VEGF:VEGFR2 autocrine feed-forward loop triggers angiogenesis in lung cancer

TL;DR: A tumor cell-autonomous VEGF:VEGFR2 feed-forward loop provides signal amplification required for the establishment of fully angiogenic tumors in lung cancer and interrupts this loop switches tumor cells from anAngiogenic to a proliferative phenotype that sensitizes tumor cells to MAPK inhibition.
