miR-519 inhibited HL60 human AML cell migration predominantly by targeting HuR. (A) A cell migration assay was performed by scratching the cell layer prior to transfection with antago-miR-519 (As-miR-519) or NC. Time-based images were captured from 0–48 h. (B) Flow cytometric analysis of the HL60 cells transfected with HuR-specific siRNA. (C) Cell migration levels were analyzed following HuR inhibition. The data are presented as the mean ± standard error of the mean (n=3) from independent experiments. *P<0.05 and **P<0.01 vs. NC. AML, acute myeloid leukemia; si, small interfering; NC, negative control; miR, microRNA; HuR, human antigen R.
