Expression of HIF-1α in NSCLC cells. (A) Expression of HIF-1α mRNA in SW900 and A549 NSCLC cell lines and normal BEAS-2B cells determined using reverse transcription-quantitative polymerase chain reaction. (B) Results of the western blot analysis of HIF-1α protein. In (A) and (B), **P<0.01 and ***P<0.001 vs. BEAS-2B; and #P<0.05 and ##P<0.01 vs. SW900. (C) mRNA and (D) protein expression of HIF-1α in NSCLC cells transfected with si-HIF-1α. In (C) and (D), **P<0.01 and ***P<0.001 vs. si-NC. HIF-1α, hypoxia-inducible factor 1α; NSCLC, non-small cell lung cancer; si-HIF-1α, small interfering RNA to HIF-1α; si-NC, small interfering RNA negative control.
