Aims: Isoliquiritigenin (ISL) is a flavonoid, that has been shown to have antioxidant, vasorelaxant, anti-inflammatory, and antitumor activities. This study aimed to explore the antitumor effect of ISL on human osteosarcoma U2OS cells and investigate the mechanism of this effect.
Methods: The effect of ISL on osteosarcoma U2OS cell proliferation, invasion, migration, and apoptosis were determined by a CCK8 assay, a transwell invasion assay, a transwell migration assay, and fluorescence-activated cell sorting, respectively.
