Expression of miR-21 and miR-4257 in NSCLC patients and healthy individuals. To investigate the miRNA expression of exosome samples, reverse transcription-quantitative polymerase chain reaction using Taqman miRNA assays was performed. (A) Comparison of exosomal miR-21 levels between the 30 healthy volunteers and 195 patients with NSCLC. Exosomal miR-21 levels showed a significant increase in the NSCLC patients (*P<0.01). (B) Comparison of exosomal miR-4257 levels between the 30 healthy volunteers and 195 patients with NSCLC. Exosomal miR-4257 levels showed a significant increase in the NSCLC patients (*P<0.01). miR/miRNA, microRNA; NSCLC, non-small cell lung cancer.
