a Stable WTAP silenced cells (sh-WTAP) and negative control (sh-NC) were constructed by Lentiviruses. The knockdown efficiency was tested by western blot assay. b The cell index curves reflecting cell number were detected by RTCA. c EdU assay was applied to compare the cell proliferation ability. d The effect of WTAP knockdown on cell invasion and migration was detected by transwell assay. Statistical signifcance, as indicated by P values, was determined by Student’s t-test: p < 0.05(*), p < 0.01(**)
