Zyflamend, a polyherbal preparation, was designed based on constituents that exhibit antiproliferative, antiinflammatory, antioxidant, antiangiogenic, and apoptotic activities through a mechanism that is not well defined. Because the nuclear factor (NF)-kappaB has been shown to regulate proliferation, invasion, and metastasis of tumor cells, we postulated that Zyflamend modulates the activity of NF-kappa B. To test this hypothesis, we examined the effect of this preparation on NF-kappaB and NF-kappaB-regulated gene products. We found that Zyflamend inhibited receptor activator of NF-kappa B ligand-induced osteoclastogenesis, suppressed tumor necrosis factor (TNF)-induced invasion, and potentiated the cytotoxicity induced by TNF and chemotherapeutic agents, all of which are known to require NF-kappa B activation. Zyflamend suppressed NF-kappa B activation induced by both TNF and cigarette smoke condensate. The expression of NF-kappa B-regulated gene products involved in antiapoptosis (inhibitor-of-apoptosis protein 1/2, Bcl-2, Bcl-xL, FADD-like interleukin-1betaconverting enzyme/caspase-8 inhibitory protein, TNF receptor-associated factor-1, and survivin) and angiogenesis (vascular endothelial growth factor, cyclooxygenase-2, intercellular adhesion molecule, and matrix metalloproteinase-9) was also down-regulated by Zyflamend. This correlated with potentiation of cell death induced by TNF and chemotherapeutic agents. Overall, our results indicate that Zyflamend suppresses osteoclastogenesis, inhibits invasion, and potentiates cytotoxicity through down-regulation of NF-kappa B activation and NF-kappa B-regulated gene products.
