Effects of matrine on expression levels of miR-133a in lung cancer NCI-H1299 cells. NCI-H1299 cells were treated with different concentrations of matrine for 24 hr (A) or with matrine (20 μg/ml) for different times (B). Real-time PCR was used to evaluate expression of miR-133a Representative results are shown from three independent experiments. (*P<0.05, **P<0.01, ***P<0.001).
