Chlorogenic acid regulates the Nrf2-NF-κB signaling pathway by activating Sirt1 in primary cortical neurons. a Western blot evaluation of the protein levels of Sirt1, IκB, HO-1, Nrf2, NF-κB 24h after OGD. b–f Quantification of western blot data of Sirt1, IκB, HO-1, Nrf2, NF-κB. ∗∗P < 0.01 and ∗∗∗P < 0.001 vs. the control group. #P < 0.05, ##P < 0.01 and ###P < 0.001 vs. the OGD group. n = 3
