The effect of miR-221/222 on autophagy of PTC cells. a, b The expression levels of miR-221/222 were quantified using qRT-PCR, following transfection. c, d Western blot (WB) was used to verify the expression of autophagy protein LC3II and P62, Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) was used as a control. (miR, microRNA; mimics, overexpression; inhibitor, interference; mimics NC, overexpression negative control; inhibitor NC, interference negative control. **P < 0.01 was considered statistically significant. Error bars indicate mean ± SD)
