Expression of miR-524-5p in human gastric cancer tissues and cell lines. (A) miR-524-5p expression in 15 pairs of gastric cancer and adjacent non-cancerous tissues was assessed by RT-qPCR. *P<0.05 vs. normal tissues. (B) miR-524-5p expression in human gastric cancer MKN-45, SGC-7901 and MGC-803 cell lines, and human normal gastric epithelial mucosa GES-1 cell line was evaluated using RT-qPCR. *P<0.05 vs. GES-1 cells. All data are reported as the mean ± standard deviation of 3 independent experiments. miR, microRNA; mRNA, messenger RNA; RT-qPCR, reverse transcription-quantitative polymerase chain reaction.
