Moreover, the result of western blot analysis implied that the EMT process was also suppressed in RB cells in response to the treatment of miR-134-5p mimics, as E-cadherin expression was obviously enhanced while the levels of N-cadherin and Vimentin were apparently reduced in these two RB cells facing miR-134-5p upregulation (Fig. 3c). Here, CDH1 is linked to retinoblastoma.
