As shown in Fig. 2C and 2D, trans-fection of HBx dramatically enhanced invasive activity compared with the EGFP vector group. Remarkably, the invasion of HBx-expressing cells was markedly inhibited by the transfection of miR-143 AS, whereas migration was not altered significantly in cells that were cotrans-fected with mock AS.
MiR-143 overexpression in HBx-transfected cells significantly promotes cell migration with no substantial effect on cell proliferation or apoptosis,Thesedata indicate that miR-143 eases HBx-controlled cell migration/invasion both in vitro and in vivo.
