| Outline of Final Research Achievements |
We exaimned the effect of TGF-β on the highly lymph nodes metastatic oral squamous cell carcinoma cell line, LM8 and its parental cell, SAS-GFP. We found that TGF-β didn't mediate their morphological change, cell to cell contact and growth. But, TGF-β induced increase in their migration and invasiveness. Epithelial-mesenchymal transition was inclined to be induced through up regulation of N-cadherin and Vimentin and enlogation of actin fiber in TGF-β stimulated cells. Additionaly, the expression of Wnt5b was elevated, not Wnt5a. Over all, these results suggest that TGF-β could increase migration and invasion of highly lymph nodes metastatic oral squamous cell carcinoma cell through EMT, in which Wnt5b could be involved.
