Figure 5From: 3,4-dihydroxyphenyl acetic acid and (+)-epoxydon isolated from marine algae-derived microorganisms induce down regulation of epidermal growth factor activated mitogenic signaling cascade in Hela cellsEGFR (phosphorylation of tyrosine) activation induced by EGF. Western blot analysis against phosphorylated form of Tyr1068 and non-phosphorylated form of EGFR was performed to examine the effects of various concentrations of EGF (0, 10, 50, 100 ng/ml for 10 min) on the activation of EGFR tyrosine kinase in HeLa cells.Back to article page
