Derived from Ginkgo biloba leaves, EGb761 is a potent bioactive compound widely recognized for its benefits in treating cerebrovascular diseases. Previous studies have demonstrated that the administration of EGb761 to VD rats enhances the proliferation, differentiation, and migration of neurons, effectively alleviating cognitive dysfunction. However, the specific mechanisms by which EGb761 exerts its remedial influence on VD persist in ambiguity. This investigation utilized an integrated approach incorporating network pharmacology with experimental procedures on HT-22 mouse hippocampal neuronal cells amidst oxygen-glucose deprivation and reoxygenation (OGD/R) to delve into certain repercussions of EGb761 on cell proliferation and migration. Results revealed that ras homolog family member A (RHOA) and B-cell lymphoma 2 (BCL-2) are potential targets of Ginkgo biloba leaves. Target genes are mainly enriched in pathways including those involved in growth hormone synthesis, secretion and action and the neurotrophin signalling pathway. Cellular experiments further demonstrated that the application of EGb761 notably enhanced the viability, proliferation, and migration of HT22 cells subjected to OGD/R through RhoA-ROCK2 pathway.

Meanwhile, the vascular hypothesis suggests that vascular damage occurs in the early stages of the disease, leading to neurodegeneration and hindered waste clearance, which in turn triggers a series of events including the accumulation of amyloid plaques and Tau protein tangles. Non-coding RNAs (ncRNAs), including long noncoding RNAs (lncRNAs), microRNAs (miRNAs), and circular RNAs (circRNAs), have been found to be involved in the regulation of AD. Furthermore, lncRNAs and circRNAs can act as competitive endogenous RNAs to inhibit miRNAs, and their interactions can form a complex regulatory network. Exosomes, which are extracellular vesicles (EVs), are believed to be able to transfer ncRNAs between cells, thus playing a regulatory role in the brain by crossing the blood-brain barrier (BBB). Exosomes are part of the intercellular carrier system; therefore, utilizing exosomes to deliver drugs to recipient cells might not activate the immune system, making it a potential strategy to treat central nervous system diseases. In this review, we review that AD is a multifactorial neurological disease and that ncRNAs can regulate its multiple pathogenic mechanisms to improve our understanding of the etiology of AD and to simultaneously regulate multiple pathogenic mechanisms of AD through the binding of ncRNAs to exosomes to improve the treatment of AD.</p>","PeriodicalId":18685,"journal":{"name":"Metabolic brain disease","volume":"40 1","pages":"84"},"PeriodicalIF":3.2,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11700052/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142927609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
