Overexpression of ADAR and ADARB1 decreases glioma cell proliferation. U87 cells were transfected with ADAR, ADARB1, and a control empty expression vector (CV). After 24 h, expression of ADAR proteins was examined using Western blot analysis (A). Cells were plated (5 × 10⁴/mL) on plastic dishes. Morphology of the cells was assessed after 24 h (B) using a phase-contrast microscope (original magnification, ×20). Direct sequencing of CYFIP2 editing site in U87 transfected cells (C). Cell number was monitored at 24-h intervals (D). Results represent the means ± SE of three independent experiments. Asterisks represent P values: *P < 0.01, **P < 10⁻³, ***P < 2 × 10⁻³.
