In conclusion, tobacco specific carcinogen, NNK, enhanced colon cancer metastasis through α7-nAChR and E-cadherin — one of the hallmarks of epithelial mesenchymal transition — and its transcription repressors, Snail and ZEB1. Besides, the nicotine also enhanced the colon cancer cell migration through non-E-cadherin pathway.

从我们的实验得知菸草中的致癌物质NNK能透过结肠癌细胞上的α7尼古丁受器而改变E-cadherin转录及其转录抑制因子(Snail和ZEB1)的表现量来增加结肠癌细胞的转移能力，而尼古丁则是透过E-cadherin以外的途径来促进结肠癌细胞转移。
