Outline of Final Research Achievements |
We analyzed expression and regulatory mechanisms for glycosyltransferase genes responsible for ganglioside synthesis in normal melanocytes and melanoma cells. Consequently, the expression level of GD3 synthase gene was high in melanoma cells, although very low in melanocytes. We also found that addition of TNFα into the culture medium and elimination of cAMP from the culture medium resulted in up-regulation of GD3 synthase gene, suggesting that signals mediated via TNFα and cAMP oppositely regulate GD3 synthase gene expression in melanocytes. On the other hand, when melanoma cells were treated by these factors, no fluctuation in the expression level of GD3 synthase gene, although GD3 synthase gene expression was remarkably decreased by treatment of IKK-inhibitor, Wedelolactone. These results suggested that ganglioside synthase genes are regulated in distinct manners between melanocytes and melanomas.
