DLEU1 and central nervous system cancer: To further explore the functions of lncRNA DLEU1 in migration and invasion of glioma cells, as shown in Figure 5A, the wound healing assay were performed, demonstrating that knocking down lncRNA DLEU1 in U87 and U251 cells could significantly inhibit migration in glioma cells, compared with the NC groups after 24 h of incubation.
