Fig. 2. Downregulation of Arc expression by siRNA transfection.
a Western blot shows that Si-Arc-1 and Si-Arc-3 significantly decreased Arc expression in cortical neurons. b No morphological changes were observed at 24 h after siRNA transfection. c Cell viability assay shows that siRNA transfection had no effect on cell viability. d LDH release assay shows that siRNA transfection had no effect on LDH release. Scale bar, 50 μm. Error bars indicate SEM (n = 6). *p < 0.05 vs. Si-control group.
