Effect of cornin on U87 cell apoptosis. U87 cells were pretreated with cornin (10, 30, 100 nM) for 48 h, followed by oxygen–glucose deprivation exposure for three hours, and reoxygenation for 24 h. Apoptosis was assess by flow cytometry using Annexin V-FITC/PI fluorescence staining. The sum of the second and fourth quadrants in the figure is the percentage of apoptotic cells. The data of apoptotic cells are expressed as the mean ± SD, (n = 3). ^**P < 0.01 vs. the control group; ^##P < 0.01 vs. the OGD/R group
