LINC00707 knockdown decreases the IC₅₀ values of DDP in A549/DDP cells. (A) LINC00707 expression levels were measured in A549/DDP cells transfected with either si-LINC00707 or si-NC using reverse transcription-quantitative PCR. (B) IC₅₀ values of DDP in either si-LINC00707- or si-NC-transfected A549/DDP cells were measured using an MTT assay. **P<0.01; ***P<0.001 vs. si-NC. IC₅₀, half-maximal inhibitory concentration; LINC00707, long intergenic non-coding RNA 00707; A549/DDP cells, DDP-resistant A549 cells; si-LINC00707, LINC00707 siRNA; si-NC, siRNA negative control.
