Figure 8. Regulatory roles of miR-338-3p on the colony formation ability of NCI-H1299 and A549 cells dependent on the ERK signal. (A, B) The number of colonies formed after transfection with miR-338-3p mimic and inhibitor treated with FR180204 or TBHQ. **P < 0.01, ##P < 0.01 and $$P < 0.01 mean that the difference is statistically significant.
