(A) Up-regulated genes (CEACAM5, NQO1, LCN2, CDH1, KRT8, EPCAM, ELF3 and KRT19) that are commonly appeared in EMT/MET pathway and the top 50 hub genes. (B) The prognostic value of KRT8 in patients with LUAD. (C) The prognostic value of KRT19 in patients with LUAD. (D) Down-regulated genes (DCN, SERPING1, GNG11, CXCL12 and CAV1) that are commonly appeared in EMT/MET pathway and the top 50 hub genes. (E) The prognostic value of DCN in patients with LUAD. (F) The prognostic value of CXCL12 in patients with LUAD.
