英文摘要:

Ewing′s sarcoma is the second most frequent primary malignant bone tumor, mainly affecting children and young adults. The notorious metastatic capability of this tumor aggravates patient mortality and remains a problem to be overcome. We investigated the effect of arsenic trioxide (As2O3) on the metastasis capability of Ewing′s sarcoma cells. We performed 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyl-2H-tetrazolium bromide assays to choose appropriate concentrations of As2O3 for the experiments. Migration, invasion, and adhesion assays were performed to assess the effect of As2O3 on the metastasis of Ewing′s sarcoma. Immunofluorescent staining was used to observe cytoskeleton reorganization in Ewing′s sarcoma cells treated with As2O3. Changes in matrix metalloproteinase-9 expression and the mitogen-activated protein kinase (MAPK) pathway were investigated using western blot. Inhibitors of p38(MAPK) (sb202190) and c-Jun NH2-terminal kinase (JNK, sp600125) were used in invasion assays to determine the effect of p38(MAPK) and JNK. We found that As2O3 may markedly inhibit the migration and invasion capacity of Ewing′s sarcoma cells with structural rearrangements of the actin cytoskeleton. The expressions of matrix metalloproteinase-9, phosphor-p38(MAPK), and phosphor-JNK were suppressed by As2O3 treatment in a dose-dependent manner. The inhibitors of p38(MAPK) (sb202190) and JNK (sp600125) enhanced the inhibition induced by As2O3, which was counteracted by anisomycin, an activating agent of p38(MAPK) and JNK. Taken together, our results demonstrate that As2O3 can inhibit the metastasis capability of RD-ES and A-673 cells and may have new therapeutic value for Ewing′s sarcoma.
