Downregulated miR-23b alleviates OGD-induced neuron injury. A, Inhibition effect of Anti-miR-23b on miR-23b expression in neurons detected by RT-qPCR. B, Apoptosis rate of neurons determined by flow cytometry. C, Protein bands of apoptosis-related proteins (cleaved caspase-3, Bax and Bcl-2) in neurons. D, Relative expression of apoptosis-related proteins (cleaved caspase-3, Bax and Bcl-2) in neurons measured by Western blot analysis. *p < 0.05 vs. the blank group; #p < 0.05 vs. OGD + LV-Anti-NC group. Measurement data were expressed by mean ± standard deviation. One-way ANOVA was conducted for multi-group data comparison, followed by Tukey's post hoc test. The experiment was repeated three times independently.
