Furthermore, we considered alternative signaling routes in cancer plasticity and spread, which revealed interesting associations between expression of ZEB1 and three genes involved in fibroblast growth factor signaling: FGF4 (R = 0.34, p = 0.04), FGF19 (R = 0.43 p = 0.0084), and FGFR1 (R = 0.28, p = 0.092). Here, ZEB1 is linked to cancer.
