After dissemination to the bone, the survival rate is \<7\%, indicating an urgent need for novel therapeutic regimes. As curcumin (diferuloylmethane) had been shown to exert strong anticancer effects against diverse human malignancies different from neurblastoma, the antiproliferative effect of curcumin on the growth of human neuroblastoma cell lines was tested. Materials and Methods: Proliferation of neuroblastoma cell lines Lan-5, SK-N-SH and Kelly under the treatment of curcumin over a broad concentration range (1{\texttimes}10-5 to 1{\texttimes}102 μM) was assessed using XTT cell proliferation assays. Possible induction of apoptosis through curcumin treatment was assessed by detection of DNA fragmentation. To investigate the effect of curcumin on NFκB activation, the protein levels of the NFκB subunit p65 of curcumin-treated cells were compared to untreated cells using Western blots. Results: Curcumin showed a significant dose-dependent antiproliferative effect on all three neuroblastoma cell lines starting at a concentration of 1{\texttimes}10-3 μM. The highest concentration of 1{\texttimes}102 μM significantly reduced the viable cell count to 8-48\% depending on the cell line. This antiproliferative effect was mediated through an increased induction of apoptosis by inhibition of NFκB, corroborating earlier findings indicating an antiapoptotic effect of NF{\^I}B. Conclusion: Our results suggest that curcumin might hold promise in the treatment of patients suffering from neuroblastoma.}, issn = {0250-7005}, URL = {https://ar.iiarjournals.org/content/28/1A/209}, eprint = {https://ar.iiarjournals.org/content/28/1A/209.full.pdf}, journal = {Anticancer Research} }
