A Pro-inflammatory cytokines, including TNF, IL-6, IL-1β, and CXCL1, were decreased following the administration of Emodin. B Different doses of Emodin attenuated OGD/R-associated apoptosis. C Different doses of Emodin inhibited OGD/R-induced apoptosis by downregulating pro-apoptosis-associated proteins such as cleaved Caspase-3/Caspase-3 and Bax, while upregulating anti-apoptosis-associated proteins like Bcl-2. Proteins that regulate apoptosis, such as p-Akt/Akt and HO-1, were also altered accordingly. Quantitative analysis of the expression compared with β-actin was shown beside
