The effect of miR-221/222 on migration, invasion, and apoptosis of PTC cells. a, b The transwell assay shows the effect of interference or overexpression of miR-221/222 on the migration of PTC cells. c, d Transwell assay shows the effect of miR-221/222 on the invasion of PTC cells. e, f Flow cytometry shows the effect of miR-221/222 on the apoptosis of PTC cells. The test was repeated independently in triplicates. Two-sample and other variance t tests were used for data treatment. (miR, microRNA; mimics, overexpression; inhibitor, interference; mimics NC, overexpression negative control; inhibitor NC, interference negative control. The scale is 20 μm.)
