The expression level of RP11-838N2.3 in LAD tissues, adjacent tissues, and cells. (a) RP11-838N2.3 expression level in A549/DDP and A549 cell. (b) RP11-838N2.3 expression level in LAD and adjacent tissues. (c) The expression levels of lncRNA RP11-838N2.3 in cisplatin-sensitive LAD cells and cisplatin-insensitive LAD cells were primary cultured. QPCR results showed that the expression level of RP11-838N2.3 in cisplatin-resistant A549/DDP cell was plainly higher than that in cisplatin-sensitive A549 cell (Mann-Whitney U test = 0.000, P ≤ 0.001). The RP11-838N2.3 expression level of LAD was also clearly higher than that of adjacent tissues (Mann-Whitney U test = 12.32, P = 0.001). ###P < 0.001; ∗∗P < 0.01.
