Protective effect of cornin in OGD/R-induced U87 cell death. A The viability of U87 cells exposed to OGD/R at different durations as assessed using the CCK-8 assay. B U87 cells were pre-incubated with different concentrations of cornin for 48 h, then underwent oxygen–glucose deprivation for 3 h, followed by reoxygenation for 24 h to detect cell viability changes. Data are expressed as the mean ± SD, (n = 6). Significance was assessed by a one-way ANOVA followed by Dunnett’s test. ^*P < 0.05, ^**P < 0.01 vs. the control group; ^#P < 0.05 vs. the OGD/R group
