Increased expression of HOXA11-AS was observed in lung adenocarcinoma tissues (3.173 ± 2.059) and lung squamous cell carcinoma tissues (5.049 ± 1.919) compared with the non-cancerous tissues (1.340 ± 0.466, 1.780 ± 0.349, respectively, both P < 0.001, Fig. 1A,B). Here, HOXA11 is linked to lung adenocarcinoma.
