However, compared with the cells singly transfected with miR-605-3p mimics, the inactivated Wnt/β-catenin pathway of the cells was reversed after cotransfected with KIF3B, suggesting that the tumor promotion effects of miR-605-3p were related with inactivation of Wnt/β-catenin pathway induced by KIF3B downregulation (Figure 5; P < 0.01). This evidence concerns the gene KIF3B and neoplasm.
