FGFR4 and glioblastoma: In addition to decreased expression of collagen network genes upon FGFR4 inactivation (compare Fig. 5C and Additional File 1: Figure S9C), we also found loss of integrin-cell surface interactions-related genes in both GBM models (BTL1528: Fig. 5E and BTL1376: Additional File 1: Figure S9D).
