Figure 1. The hepatic inflammatory microenvironment promoted the proliferation, migration, and invasion of lung adenocarcinoma (LUAD) cells. The IL-6-stimulated inflammatory microenvironment simulated by liver cells (our hepatic inflammatory microenvironment model) significantly promoted the (A) proliferation, (B) migration, and (C) invasiveness of A549 and H1975 LUAD cells and (D) significantly increased the secretion of the primary hepatocyte inflammatory factors CRP, TNFα, and IL-22 (*P<0.05, **P<0.01 versus the control group).
