| Research Abstract |
Our study of EMT (epithelial to mesenchymal transition), which is closely involved in a process of cancer metastasis, led to the following results:
1) Downregulation of E-cadherin and overexpression of SIP1 were considered to be predictive of cervical lymph node metastasis of tongue squamous cell carcinoma.
2) Ang2 was shown to enhance metastatic ability of breast cancer cells by promoting cell survival ability via suppression of apoptosis, in addition to induction of EMT.
3) Selective Cox2-inhibition was revealed to include suppression of EMT in its anti-tumor effect.
