Background: Glioblastoma is the most common type of malignant tumor of the brain. Despite substantial improvements in therapy, the 5-year survival rate of patients with glioblastoma remains low. Antitumor drug development has encountered considerable obstacles, which can be attributed to metastasis and the bloodbrain barrier (BBB). Hesperetin (HSP), derived from citrus fruits, exhibits several biological properties, including anticancer and anti-inflammatory activities. In addition, in vitro models have shown that HSP can easily cross the BBB. The purpose of the present study was to explore the effects and underlying mechanisms of HSP on glioblastoma cells.Methods: GL261 cell were cultured and treated with different dose HSP. The cell viability was assessed with Cell Counting Kit-8 (CCK-8) assay. The cell apoptosis was determined using an Annexin V/propidine iodide (PI) staining and Hoechst staining and detection assay, cell migration and invasion were observed on GL261 cells using Matrigel-coated Transwells and Wound-Healing assay. The expression of proteins was detected by Western blotting.Results: HSP suppressed cell proliferation and could induce apoptosis, the latter of which might be regulated through the Phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) and nuclear factor-kappa B (NF-κB) pathways. Furthermore, HSP inhibited cell migration and invasion by downregulating the expression of matrix metalloproteinase-2 (MMP-2) and MMP-9, and inhibited epithelial-mesenchymal transition (EMT) by upregulating the expression of E-cadherin while downregulating N-cadherin and vimentin expression.Conclusions: These findings suggest HSP to be an alternative preventive and therapeutic antiglioblastoma drug that may be especially useful for patients with recurrent glioblastoma.
Background and Objective: Ischemic cerebrovascular disease is one of the main diseases threatening human health and survival and is a commonly occurring disease in neurology. Due to its high disability rate, ischemic cerebrovascular disease is one of the most important diseases to be prevented and treated at present. The risk factors of cerebral ischemia include atherosclerosis, hypertension, hyperlipidemia, and blood viscosity caused by thrombocytosis. After cerebral ischemia, cerebral ischemia-reperfusion injury may be induced by oxidative stress (OS), inflammatory reaction, nitric oxide damage, apoptosis, excitatory amino acid toxicity, calcium (Ca 2+ ) overload, and other mechanisms. Hesperidin is a flavanone compound and is a key component in citrus plants. It is a kind of traditional Chinese medicine extract with high levels of Pericarpium, shell, fruit, and green peel. In recent years, Hesperidin has received great attention, compelling evidence has indicated Hesperidin plays a beneficial role in cerebral ischemia. Methods: We conducted a literature search for published manuscripts hesperidin in ischemia/ reperfusion up to December 2021 in common English databases (i.e., PubMed, EMBASE, Web of Science, SpringerLink, Wiley, Cochrane Library) and Chinese databases [Chinese BioMedical Literature Service System (CBM), WANFANG database, China Knowledge Resource Integrated Database (CNKI)].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
