['Nuclear factor-κB (NF-κB) has been implicated in tumor cell proliferation and survival and in tumor angiogenesis. We sought to evaluate the effects of curcumin, an inhibitor of NF-κB, on a xenograft model of disseminated neuroblastoma.', 'For in\xa0vitro studies, neuroblastoma cell lines NB1691, CHLA-20, and SK-N-AS were treated with various doses of liposomal curcumin. Disseminated neuroblastoma was established in\xa0vivo by tail vein injection of NB1691-luc cells into SCID mice, which were then treated with 50 mg/kg/day of liposomal curcumin 5 days/week intraperitoneally.', 'Curcumin suppressed NF-κB activation and proliferation of all neuroblastoma cell lines in\xa0vitro. In\xa0vivo, curcumin treatment resulted in a significant decrease in disseminated tumor burden. Curcumin-treated tumors had decreased NF-κB activity and an associated significant decrease in tumor cell proliferation and an increase in tumor cell apoptosis, as well as a decrease in tumor vascular endothelial growth factor levels and microvessel density.'] Does liposome-encapsulated curcumin suppress neuroblastoma growth through nuclear factor-kappa B inhibition?
