Fig. 1: LncRNA SNHG17 was elevated in gefitinib-resistant LUAD.

A qRT-PCR analysis of lncRNA SNHG17 in normal (n = 36), gefitinib-sensitive (n = 23), and gefitinib-resistant (n = 13) LUAD tissues. B qRT-PCR detection of lncRNA SNHG17 in LUAD cells (PC9 and A549) and gefitinib-resistant LUAD cell lines (PC9/GR, A549/GR). BEAS-2B was used as a normal control. The data were expressed as the mean ± SD of n = 3 experiments. **P < 0.01; ***P < 0.001.
