Fig. 5From: Water-pipe smoking promotes epithelial–mesenchymal transition and invasion of human breast cancer cells via ERK1/ERK2 pathwaysQuantification of the western blot analysis of E-cadherin, FAK and Erk1/Erk2 phosphorylation as well as GAPDH in MCF7 and BT20 exposed to WPS and unexposed (control) cells. This analysis confirms the downregulation of E-cadherin in both cell lines; in parallel, WPS enhances FAK expression and Erk1/Erk2 phosphorylation in the two cell lines in comparison with their control cells.
