Purpose: Prostate cancer is the most common male cancer all over the world. Triptolide, one of the components from the Traditional Chinese Medicine Tripterygium wilfordii, has been shown to induce cell death of many human solid tumor cells such as breast, lung, pancreatic, bladder, cervical and colorectal cancers. But its effects on prostate cancer cell have never been revealed in aspects of proliferation or apoptosis, not to mention on migration and invasion capacities. The information prompts us to evaluate the potential anticancer efficacy of triptolide in the prevention and therapy of Taiwan prostate cancer.
Materials and Methods: In the first step, we have examined and revealed the mechanisms of proliferation inhibition and apoptosis induction of triptolide in prostate cancer cell lines, DU145 and PC3. In addition, we have also examined the metastasis capacity of these prostate cancer cell lines via wound scratch, wound healing, transwell, matrigel invasion assays, and revealed the involved signaling pathways and molecules. 
Results: In summary, in the DU145 and PC3 prostate cancer cell lines, finding that triptolide suppressed the overall cell survival of DU145 and PC3 prostate cancer cells. In addition, we have found that the mechanism may be related to induction of cancer cell apoptosis, not to simply proliferation.
Conclusion: We have found NF-kappaB-dependent pathway critically involved in triptolide’s inhibition of migration and invasion.
