Moreover, in both cohorts the expression of LIF correlated significantly with the expression of FGFR4 (p < 0.05) (Fig. 1 O and T), while the Kaplan–Meier plotter survival analysis of ACRG repository confirmed the results of our cohort of patients, showing that high levels of FGFR4 correlated with a poor survival in the diffuse sub-type of GC (Supplementary Fig. 3 K). Here, FGFR4 is linked to gastric cancer.
