Autophagy is closely related to the formation and development of multiple human tumors including ovarian cancer. As a major regulator of this process, the role of mTOR (mammalian target of rapamycin) has been well proven. Cardamonin, a kind of flavonoid from plants, has effects on induction of autophagy and thus antiproliferation of cancer cells. However, the detailed mechanism remains unclear. DAP1 (death-associated protein 1) is a proline-rich protein, which is involved in the regulation of cellular growth and programmed cell death including autophagy and apoptosis. The aim of this study was to investigate whether DAP1 is involved in proliferation inhibition and autophagy induced by cardamonin in tumor cells. Using online bioinformatics tools, we found that DAP1 expression is closely related to the survival of patients with ovarian cancer. Our study showed that autophagy induced by cardamonin was associated with mTOR inhibition, and DAP1 was involved in this process. Silence of DAP1 decreased cell proliferation but enhanced the antiproliferative effect of cardamonin in SKOV3 cells. The level of autophagy was elevated by DAP1 silencing in SKOV3 cells. Notably, cardamonin showed higher autophagy flux in the DAP1 small interfering RNA group. Taken together, our results implied that DAP1 negatively regulates autophagy induced by cardamonin, and it may be a potential target for ovarian cancer therapy.
