[Methods] The viabilities of HCE-4 cells were measured by MTT assay. The induction of active components from A. membranaceus on apoptosis of HCE-4 cells was detected by Annexin V-FITC/PI double staining. The apoptotic-related protein expression levels were determined by Western blotting. [Results] Formononetin and astragaloside IV suppressed the proliferation of HCE-4 cells in a dose-dependent manner. The Annexin V-FITC/PI double staining results showed that formononetin and astragaloside IV could induce HCE-4 cells apoptosis in a time-dependent manner. The Western blotting results showed that formononetin and astragaloside IV could significantly down-regulate p-AKT,pro-caspase-3,and increase cle-caspase-3 protein expression in HCE-4 cells. [Conclusions]Active components from A. membranaceus such as formononetin and astragaloside IV significantly inhibited the proliferation of human esophageal cancer HCE-4 cells by inducing mitochondrial dependent apoptosis via AKT signaling pathway.展开更多
