Fig. 3: LncRNA NORAD targets miR-520g-3p/SMIM22 in NSCLC tissues.

A–C The levels of lncRNA NORAD, SMIM22 mRNA, or miR-520g-3p level in adjacent tissue (N = 31) and NSCLC tissues (N = 31). D, E The protein level of SMIM22 in NSCLC tissues and adjacent tissues (N = 8). F, G The linear regression and correlation analyses between miR-520g-3p and lncRNA NORAD, or between miR-520g-3p and SMIM22. H–J The ROC curve of lncRNA NORAD, miR-520g-3p, or SMIM22 in the NSCLC patients. Error bars represent the means ± SEM of three independent experiments. ROC: Receiver Operating Characteristic. ∗∗p < 0.01.
