Epithelial-Mesenchymal Transition Markers and HER3 Expression Are Predictors of Elisidepsin Treatment Response in Breast and Pancreatic Cancer Cell Lines
Figure 2
Expression of EMT markers associated with elisidepsin sensitivity in breast cancer cell lines.
Protein expression levels of different EMT markers were evaluated by immunocytochemistry (A), western blot (B) and IHC (C). A) Immunocytochemistry of two epithelial (E-cadherin and β-catenin) and four mesenchymal markers (vimentin, Slug, Snail and Twist). Magnification 100x. B) E-cadherin, β-catenin, Slug, Snail, Twist, vimentin and β-actin (loading control) were detected by western blot analysis using 50 µg of total protein. C) Basal levels of E-cadherin, β-catenin and vimentin were analyzed by IHC. Magnification 20x. Each experiment was performed at least in duplicate.
