Figure 7. The neuroprotection of LyA involved the Nrf2/HO-1 pathway. (A–C) Cells were transfected with control or HO-1 and Nrf2 siRNA for 48 h, followed by treatment with 40 μM LyA for 8 h. HO-1 and Nrf2 expression levels were analyzed by western blotting. Data were presented as mean ± SD (n =6). *p < 0.05 vs si-control group without LyA; #p < 0.05 vs si-control group with LyA. (D) Cells were treated for 48 h with control or siRNA, and then treated with 40 μM LyA for 8 h before being subjected to 60 min OGD followed at 24 h by the MTT assay. (E) Intracellular ROS level. Data were represented as means ± SD (n=6). *p < 0.05 compared with OGD group; #p < 0.05 compared with OGD + LyA group.
