Finally, as shown in Figure 5(g-i), we proved that both miR-6734-3p overexpression and ZEB2 ablation restrained cell proliferation (P < 0.05, Figure 5(g,h)) and induce cell apoptosis (P < 0.05, Figure 5(i)) to sensitize CR-NSCLC cells to cisplatin stimulation, which were examined by CCK-8 assay and FCM assay, respectively. Here, ZEB2 is linked to non-small cell lung carcinoma.
