Figure 2. GAL-1 expression is correlated with GLI1, and GLI1 expression is correlated with VM. (A) Representative images of IHC indicating GLI1 and GAL-1 protein expression in GC tissues (×200 magnification). (B) The GAL-1 IHC scores in GLI1-positive GC tissues were significantly higher than the GAL-1 IHC scores in GLI1-negative GC tissues(P < 0.01) (C) GAL-1 IHC scores were positively correlated with GLI1 IHC scores in GC tissues (r = 0.958; P < 0.01). (D) GC tissues exhibiting high GLI1 expression were more likely to form VM (endogenous cell-dependent vessels are indicated by the red dotted line, VM is indicated by the green dotted line, and red blood cells are indicated by red arrows in VM and endogenous cell-dependent vessels; ×400 magnification). (E) The GLI1 IHC scores in GC tissues with VM were significantly higher than those without VM (P < 0.01).
