Fig. 4From: Water-pipe smoking promotes epithelial–mesenchymal transition and invasion of human breast cancer cells via ERK1/ERK2 pathwaysWestern blot analysis of E-cadherin, FAK and p-Erk1/Erk2 in MCF7 and BT20 cell lines under the effect of WPS. We notice that WPS decreases/increases the expression patterns of E-cadherin and FAK, respectively, in both cell lines in comparison with control cells; meanwhile, WPS stimulates Erk1/Erk2 phosphorylation in these two cell lines. GAPDH was used as a control. Cells were treated with WPS solution as explained in “Materials and methods” section as well as “Results” sectionBack to article page
