| Research Abstract |
Epithelial-Mesencymal Transition(EMT) is involved in tumor invasion and metastasis of oral squamous cell carcinomas(SCCs). Snail, a transcription factor and EMT inducer, directs transcription of its target genes for the acquisition of EMT in SCC cells. We focused a process of loss of epithelial integrity among SCC cells during the EMT. For the investigation of that, we generated SCC cell pools of forced Snail expression by recombinant virus infection system. Almost the cells displayed constant expression of exogenous Snail, however, a small population of the cells underwent EMT. The cells on culture dish were given the migration area and were escalated into EMT. Immnocytochemistory and immnoblot analyses showed that loss of epithelial integrity and cell-cell contact were the last step of EMT process and the process was accelerated by distinct humoral factors.
