Therapeutic potential of curcumin in prostate cancer—IV: Interference with the osteomimetic properties of hormone refractory C4‐2B prostate cancer cells

Abstract

The highly metastatic C4-2B prostate cancer cell line is already "programmed" to exhibit the bone-like properties that would at least in part explain its affinity to set up osseous metastases. Curcumin is able to interfere with the osteoblastic component as well as the osteoclastic component of this phenotype, by interfering with the growth factor receptor pathways and by inhibiting the NF-kappa B activation process. It is concluded that curcumin may inhibit the growth factor collaboration between the prostate cancer cells and the osteoblast/stromal cells, thus exhibiting a potential to prevent the establishment of bony metastases.
