Figure 1. LncRNA SDPR-AS was down-regulated NSCLC tissues (A) and cells (B). NSCLC: non-small cell lung cancer AC: adenocarcinoma; SCC: squamous cell carcinoma; LCC: large cell carcinoma; SCLC: small cell lung cancer. Data were presented as mean ± standard deviation. *p < .05, **p < .01 and ***p < .01 compared with corresponding controls.

Figure 2. Down-regulation of SDPR-AS promoted NSCLC cell proliferation and inhibited cell apoptosis. NSCLC cell lines H522, H661 and H520 were transfected with pcDNA-SDPR-AS, sh-SDPR-AS or their corresponding controls. (A) SDPR-AS was confirmed to be successfully overexpressed and knocked down in H522, H661 and H520 cells. (B) Effects of SDPR-AS dysregulation on H522 cell viability, colony forming ability and apoptosis. (C) Effects of SDPR-AS dysregulation on H661 cell viability, colony forming ability and apoptosis. (D) Effects of SDPR-AS dysregulation on H520 cell viability, colony forming ability and apoptosis. Data were presented as mean ± standard deviation. *p<.05, **p<.01 and ***p<.01 compared with corresponding controls.
