Abstract | BACKGROUND: The putative functions of the cellular prion protein (PrP(c)) are believed to be associated with cell signaling, differentiation, survival, and cancer progression. With respect to cancer development and progression, elevations and mutations of PrP(c) expression have been shown to increase the risk for malignancy and metastasis in breast and colorectal cancer. Since both natural supplements and direct regulation of PrP(c) expression contribute to inhibition of cancer progression and growth, we hypothesized that knockdown of PrP(c) could lead to an enhanced synergic effect on the inhibition of cancer growth by fucoidan. MATERIALS AND METHODS: RESULTS: CONCLUSION: Combination of fucoidan with silencing of PrP(c) has a synergic effect on the inhibition of HT29 colon cancer cell growth. Furthermore, we provide evidence for the therapeutic application of PrP(c) silencing with other anticancer drugs for cancer.
