Silencing lncRNA FOXD2-AS1 inhibits proliferation, migration, invasion and drug resistance of drug-resistant glioma cells and promotes their apoptosis via microRNA-98-5p/CPEB4 axis

Figure 2. Silencing of FOXD2-AS1 results in inhibition of the proliferation, migration, invasion and EMT of glioma U87 cells and promotion of their apoptosis (Data of U251 cells were shown in Supplementary Figure 1). (A) The expression of FOXD2-AS1 in U87 cells were detected by RT-qPCR. (B) EdU assay was used to detect proliferation of U87 cells. (C) The ability of cell colony formation of U87 was detected by colony formation assay; (D) Flow cytometry was used to detect cell apoptosis of U87 cells in each group. (E) Cell migration ability of U87 cells was tested by scratch test; (F) Transwell assay was used to detect cell invasion of U87 cells in each group. (G) Western blot analysis was conducted to detect the expression of factors related to EMT in U87 cells. * P < 0.05 vs the sh-NC group; The data were all measurement data, represented by mean ± standard deviation. The comparison between the two groups was statistically analyzed by independent sample t test, and the experiment was repeated for three times.
