qRT-PCR analysis of miRNA expression in EVs from NSCLC patients and healthy controls. The qRT-PCR analysis of miR-20a-5p (a), miR-20b-5p (b), miR-30b-5p (c), miR-451a (d), and miR-665 (e) expression in EVs from ADC, SQCC, and CTRL, or between NSCLC and CTRL are shown. The qRT-PCR data were normalized to cel-miR-39. An unpaired Student’s t test was used for equal variances, and Welch’s t test was used for unequal variances. *P < 0.05, **P < 0.01. Results are presented as mean ± SEM
