Abstract

Carcinogenesis is predominantly dependent on the cancer stem cells (CSCs) residing or populating within the cancer. We previously demonstrated that the novel synthetic genistein analogue, 7-difluoromethoxyl-5,4'-di-n-octylgenistein (DFOG), induced apoptotic cell death of ovarian and gastric cancer cells. The present study demonstrated that sphere‑forming cells (SFCs) derived from the ovarian cancer cell-line SKOV3 possessed ovarian cancer stem-like cell (OCSLC) properties, including self-renewal and high tumorigenicity. DFOG may be effective in inhibiting the self‑renewal capacity of SFCs derived from the SKOV3 cell line. DFOG decreased the level of phosphorylated FOXO3a protein in SKOV3 cell‑derived SFCs. The inhibition of FOXO3a expression by siRNA significantly attenuated the ability of DFOG to inhibit the self-renewal capacity of SKOV3-derived SFCs. Our results suggested that DFOG has been demonstrated to significantly inhibit the self-renewal capacity of ovarian cancer stem cells (OCSCs) through a mechanism partly dependent on the activation of FOXO3a.
