FGFR1 and glioblastoma: These data led us to identify a six genes set defined from our in vitro results, involved in GSLC radioresistance and associated to patient overall survival when treated by the standard chemo-radiotherapy treatment and confirm our in vitro data demonstrating that FGFR1-dependant GSLC radioresistance pathways is a central actor of GBM treatment resistance.
