Prostate cancer is one of the most common malignancies in men, and it urgently demands precise interventions that target the signaling pathways implicated in its initiation, progression, and metastasis. The Notch-1 signaling pathway is closely associated with the pathophysiology of prostate cancer. This study investigated the antitumor effects and mechanisms of curcumin, which is a well-known natural compound from curcuminoids, in prostate cancer cells. Viability, proliferation, and migration were analyzed in two prostate cancer cell lines, DU145 and PC3, after curcumin treatment. Whether the Notch-1 signaling pathway is involved in the antitumor effects of curcumin was examined. Curcumin inhibited the survival and proliferation of PC3 and DU145 cells in a dose- and time-dependent manner and inhibited DU145 migration. Curcumin did not affect the expression of Notch-1 or its active product NICD, but it did inhibit the expression of MT1-MMP and MMP2 proteins in DU145 cells. We found that curcumin inhibited the DNA-binding ability of NICD in DU145 cells. In conclusion, curcumin inhibited the survival and metastasis of prostate cancer cells via the Notch-1 signaling pathway.
