Figure 4From: 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 cellsMorphological changes of HeLa cells by the treatment of compounds. The cells were treated with each compound (50 μg/mL for 24 or 48 h) and EGF (10 ng/mL for 10 min), except for the control cells treated with EGF only.Back to article page
