In this study, observed results revealed that Dkk-3 induced the apoptosis in 4T1 breast cancer cells and apoptotic effects of Dkk-3 intensified following photodynamic therapy. This study provided a novel insight into the development of therapeutic strategies for treatment of breast cancer using Dkk-3 combined with PDT.
