Background and objective Our previous in vivo experiment (paper has been published) has confirmed Feiyanning’s regulation effect on epithelial cell markers Alpha-catenin, beta-catenin, E-Cadherin and mesenchymal cell markers N-cadherin, Fibronectin, vimentin. Based on previous study, the objective of this study is to further investigate the expression of epithelial-mesenchymal cell marker gene and protein intervened by Feiyanning in highly metastatic lung cancer cells 95-D in vitro. Methods Human highly metastatic lung cancer 95-D cells were treated with different concentrations of Feiyanning in vitro, and then Real-time PCR and Western blot methods were used to detect mRNA and protein expression of epithelial-mesenchymal cell marker factor Alpha-catenin, beta-catenin, E-Cadherin, N-cadherin, Fibronectin and vimentin. Results Real-time PCR results showed that compared with the control group, Feiyanning at 20% concentration remarkably up-regulated the expression of Alpha-catenin (P
