| Research Abstract |
Wnt sinaling pathway has a crucial role in tumorgenesis. Some report have demonstrated that this signaling pathway was activated in melanoma. In this study, we evaluated whether celecoxib, a NSAIDs inhibited Wnt signaling pathway or not. If celecoxib suppressed Wnt signaling, this drug can be used as a molecular targeting drug. The expression of beta-catenin in melanoma samples was assessed by immunohistochemistry. Some melanoma samples expressed beta-catenin. Next, celecoxib was administrated in cell culture medium of melanoma cells. This experiment revealed that celecoxib inhibited the growth of melanoma cells. The relationship between the amount of beta-catenin in melanoma cells and the extent of growth suppression of melanoma cells was investigated, suggesting correlation of Wnt signal activation and the effect of growth inhibition of melanoma cells.
