Circ_0007142 was enhanced in lung adenocarcinoma tissues and correlated with poor prognosis. A. 32 differentially expressed lncRNAs were upregulated in lung adenocarcinoma tissues and paracancerous tissues. B. The expression of circ_0007142 was most up-regulated in lung adenocarcinoma tissues. C. The expression of circ_0007142 in 60 pairs of lung adenocarcinoma tissues and adjacent normal tissues. D. Circ_0007142 expression was obviously higher in patients with advanced clinical stage (III phase) than that with early clinical stage (I-II phase). E. Kaplan-Meier curves of overall survivals and log-rank test showed that patients with high circ_0007142 expression had poor overall survivals. *P<0.05 compared to normal, I-II group; **P<0.01 compared to normal group.
