Figure 3. MiR-214-3p suppresses CRC cell metastasis in vitro and in vivo. (A–C) Transwell assays revealed that miR-214-3p suppressed CRC cell migration and invasion abilities. (D–E) Western blot analysis revealed that miR-214-3p decreased the expression of N-cadherin and vimentin and increased the expression of E-cadherin and Zo1. (F–I) More lung metastatic nodules were observed in the LV-miR-214-3p group than in the LV-INC group. (J–K) IHC analysis indicated that the expression of E-cadherin was lower and that the expression of N-cadherin was higher in xenograft subcutaneous tissues from the LV-miR-214-3p inhibitor group. The data are represented as the means±S.D. from at least three independent experiments. *p<0.05.
