miR-129-5p expression levels in primary tissues (in vivo) and cell lines (in vitro). (A) Primary lung cancer tissues and corresponding adjacent non-cancer tissues were collected from 20 patients and miR-129-5p levels were determined by stem-loop RT-qPCR. All samples were performed in triplicate. (B) Normal human lung fibroblast cells MRC-5 and non-small cell lung cancer cells A549 were collected and miR-129-5p expression levels were determined by stem-loop RT-qPCR. Data are presented as the mean ± standard deviation of three independent experiments. *P<0.05; **P<0.01. RT-qPCR, reverse transcription-quantitative polymerase chain reaction.
