Figure 6. WTAP promotes the malignant progression of glioblastoma cell lines. (A) A colony formation assay was used to explore the effect of WTAP on the proliferation ability of U87 and U251 cells. (B, C) A wound-healing test was used to determine the effect of WTAP on the migration ability of U87 and U251 cells. (D, E) The invasion ability and migration ability were measured by transwell assay. *P < 0.05; **P < 0.01; ***P < 0.001.
