miR-107 reduces the expression level of TPD52. (A) The mRNA expression level of TPD52 in differing groups; (B) The protein expression level of TPD52 in different groups; (C) The quantitative result of B was presented. **P<0.01, vs NC group. Control, untreated cells; NC, microRNA-107 mimics negative control-transfected cells; miR-107 mimics, microRNA-107 mimics-transfected cells; TPD52, tumor protein D52; GAPDH, glyceraldehyde 3-phosphate dehydrogenase.
