    Abstract:
    Scutellarein, a flavone found in the perennial herb Scutellaria baicalensis, has antitumorigenic activity in multiple human cancers. However, whether scutellarein can attenuate ovarian cancer (OC) is unclear. This study investigated the effects of scutellarein in OC. In vitro cell viability was assessed using MTT assay whereas proliferation was assessed using 5-ethynyl-2'-deoxyuridine and colony formation assays. Cell apoptosis was detected by an Annexin V-fluorescein isothiocyanate/propidium iodide assay. Wound-healing and Transwell assays were used to determine cell migration and invasion. The differential expression of enhancer of zeste homolog 2 (EZH2) and forkhead box protein O1 (FOXO1) was measured by Quantitative real-time PCR and western blot analysis. We found that scutellarein inhibited viability, migration, invasion of A2780 and SKOV-3 cells, and reduced the expression of EZH2 in OC cells. In addition, FOXO1 was downregulated in OC tissues and cells and negatively regulated by EZH2. Also, scutellarein inhibited tumor growth and metastasis in vivo. In conclusion, scutellarein alleviates OC by the regulation of EZH2/FOXO1 signaling.
