LncFOXO1 was down-regulated in lung cancer tumor tissues and cells. (A) The expression levels of lncFOXO1 in lung cancer tissues and adjacent tissues were examined by qRT-PCR; (B) The expression level of lncFOXO1 in lung cancer cells (A549, H460, HCC827 and H1299) and lung fibroblast IMR-90 cells were detected by qRT-PCR. Data are presented as the mean ± SD of three independent experiments; * P<0.05, ** P<0.01, *** P<0.001. LncFOXO1: long non-coding RNA FOXO1; qRT-PCR: quantitative real time PCR
