Melanoma is highly malignant, particularly prone to metastasizing to the skin. The incidence of melanoma varies markedly between countries, and is relatively low in China. The aim of the present study was to investigate the antitumorigenic effect of damnacanthal on melanoma cells, and its molecular mechanism. MUM-2B cells were treated with 0-20µM damnacanthal for 12, 24 and 48 h., it was demonstrated that damnacanthal inhibited proliferation and promoted apoptosis of melanoma cells in a dose- and time-dependent manner. Damnacanthal treatment increased caspase-3/8 and 9 activity, and promoted B-cell lymphoma 2-associated X protein, tumor protein p53 (p53) and p21 protein expression levels in melanoma cells. Damnacanthal treatment also resulted in downregulated nuclear factor-κB (NF-κB), cyclin D and cyclin E protein expression in melanoma cells. In conclusion, the results of the present study demonstrated that the antitumorigenic activity of damnacanthal on melanoma cells is executed via the p53/p21 and NF-κB/cyclin/ caspase-3 signaling pathways.
