24, 45 In previous studies, we reported an oncogenic role of TRIB2 in lung adenocarcinoma, and proved that miR-511 and miR-1297 could suppress A549 cell proliferation in vitro and in vivo by suppressing TRIB2 and increasing C/EBPα expression.20 Here we further demonstrated that TRIB2 were higher in adenocarcinoma samples and patients with greater TRIB2 had a poor survival. The gene discussed is CEBPA; the disease is lung adenocarcinoma.
