Hallmarks of the pathophysiology of glaucoma are oxidative stress and apoptotic death of retinal ganglion cells(RGCs).Ginkgo biloba extract (EGb) with multi-target,multi-pathway functions has been reported to exert positive pharmacological effects on oxidative stress and damaged RGCs.However,the ingredients and anti-apoptotic targets of EGb in the treatment of open-angle glaucoma (OAG) have not been fully elucidated.Therefore,in-depth analysis is necessary for further research.Ginkgo biloba-re-lated and anti-apoptotic targets were identified and then combined to obtain the intersection,representing the potential anti-apoptotic targets of Ginkgo biloba.In addition,compound-anti-apoptotic target and OAG-target protein-protein interaction network were merged to obtain five core genes and compound-OAG-anti-apoptotic target protein-protein interaction network.Consequently,the active com-pounds and anti-apoptotic targets of Ginkgo biloba in the treatment of OAG were identified,namely luteolin,β-sitosterol,kaempferol,stigmasterol,quercetin,and p53,Bax,Bcl-2,Caspase-3 and Caspase-9,respectively.For the anti-apoptotic targets of Ginkgo biloba in the treatment of OAG,Gene Ontology (GO) and pathway analysis were executed to confirm the gene functions of Ginkgo biloba in antagonizing apoptosis of RGCs.The pathway enrichment was mainly involved in transcriptional activation of p53 responsive genes,activation of caspases and apoptotic processes.Finally,we confirmed the results of the network analysis by H2O2 treated RGC-5 cells in vitro.The results demonstrated that EGb protection can effectively diminish H2O2-induced apoptosis by inhibiting p53 acetylation,reducing the ratio of Bax/Bcl-2 and suppressing the expression of specific cleavage of Caspase-9 and Caspase-3.
