LINC00261 expression was down-regulated in LC tissues and cells and was associated with overall survival. a The level of LINC00261 in LC tissues (LC, n = 78) and adjacent normal lung tissues (normal, n = 78) determined by qRT-PCR. b The Kaplan–Meier analysis of LINC00261 in relation to overall survival rate in patients with LC. c The level of LINC00261 in BEAS-2B cells and A549, H1299, H23, SPC-A1 and L78 cells. ^##P < 0.001 vs. BEAS-2B. All experiments were conducted independently in triplicate
