IGF1 and gastric cancer: In diffuse GC, but not intestinal GC, CYP1A1 expression was strongly correlated with the expression of genes involved in proliferation (IGF1, p = 0.001), EMT signature such as VIM, p = 0.007; SLUG and ZEB2 (p = 0.04); and migration (MMP2, p = 0.01); these genes were previously shown to be correlated with IGF1 [10].
