miR-4775 suppression reduced the tumor-suppressive effects of LINC00152 inhibition on U-118 MG cells. U-118 MG cells were transfected with sh-LINC00152 1#, miR-4775 inhibitor, and corresponding control (NC). (A) Cell viability, (B) migration, (C) invasion, (D) apoptosis, and (E) protein levels of apoptosis-associated factors were detected by CCK-8, Transwell, flow cytometry, and Western blot, respectively. *p < 0.05, **p < 0.01, ***p < 0.001.
