GLI2 is upregulated in gastric cancer and indicates a poor survival. a, b The mRNA and protein expression of GLI2 in six gastric cancer cell lines and GES-1. c, d GLI2 mRNA expression in GC in GEPIA and TCGA databases. e The relative GLI2 mRNA expression in 21 pairs of gastric cancer and adjacent normal tissues. f, g Protein expression and immunohistochemical staining of GLI2 in representative GC patients mentioned above. h, i Survival analysis based on K-M Plotter. (Scale bar = 100 μm, *p < 0.05, **p < 0.01, ***p < 0.001, ns = no significance)
