Genes (RAB27b RAS family, IL-1RA, IL-33, chemokine ligand 6, epiregulin, EGF-like domain and cathepsin) related to cancer development (Wnt signaling pathway) and inflammation (chemokine/cytokine signaling pathway, Toll receptor signaling) were up-regulated while genes (troponin, tropomodulin 2, endothelial lipase, FGFR4, integrin alpha8 and adenylate cyclase 8) related to the tumor suppression such as p53 pathway, TGF-beta signaling pathway and cadherin signaling pathway were down-regulated by K-ras oncogene.
