Abstract/OtherAbstract:
We have reported that treatment with trientine, Cu-chelating agent, inhibits tumor growth in a murine transplantation model using fibrosarcoma and induces apoptosis in tumor cells in vivo and in vitro. When fibrosarcoma cells were treated with 10 mM trientine, the activities of p38 MAPK in treated cells were approximately 3-4 times higher than those in untreated cells. Proportions of cells in which apoptosis was induced by trientine increased in an incubation time-dependent manner from days 2 to 6. The proportions of apoptotic cells in the cells treated with trientine and SB203580, an inhibitor of p38 MAPK, were approximately 50% in those of cells treated with trientine alone. The present results showed that the p38 MAPK pathway may play an important role in induction of apoptosis in fibrosarcoma cells by trientine.
