Figure 9From: 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 cellsRelative inhibitory effects of the compounds to Tyrphostin AG 1478 on the activities. HeLa cells were pre-incubated with different concentrations of each compound or AG 1478 (10 μg/mL) for 40 min and then stimulated with EGF (10 ng/ml for 10 min). Western blot analysis performed with the indicated antibodies.Back to article page
