IGF-1R is a direct target of miR-10b in cervical cancer. (A) Predicted miR-10b target sequence in the 3′UTR of IGF-1R and positions of mutated nucleotides in the 3′UTR of IGF-1R. (B) HEK293T cells were transfected with luciferase report vectors, together with miR-10b mimics or NC. Luciferase activities were measured at 48 h post-transfection. (C) The protein expression levels of IGF-1R were determined by western blot analysis. *P<0.05. IGF-1R, insulin-like growth factor-1 receptor; miR-10b, microRNA-10b; UTR, untranslated region; Wt, wild type; mut, mutant; NC, negative control.
