Western blotting with tumor tissue samples also showed that treatment with DHA led to marked decreases in the expression of PDGFRα, and inactivation of AKT and ERK and the repression of the EMT phenotype, that is, the upregulation of E-cadherin and downregulation of N-cadherin and vimentin and twist (Figure 5e). This evidence concerns the gene CDH1 and neoplasm.
