Differential expression of epithelial–mesenchymal transition (EMT) markers in MCF-7 o/e Snail cells and MCF-F o/e Snail tissues. Proteins expressions of EMT markers of MCF-7 cells, MCF-7 o/e Snail cells and those obtained from tumor tissue via intratibial injection of MCF-7 o/e cells, denoted as MCF-7 o/e Snail tissues were analyzed with Western blot (a) and quantified (b). The transcripts encoding these proteins such as E-cadherin (c), N-cadherin (d), and Vimentin (e) were analyzed with real-time PCR. *p < 0.05 vs MCF-7 cells by student t test; ^#p < 0.05 vs MCF-7 o/e Snail (cells) by student t test
