N-(p-Coumaroyl)serotonin (CS) with antioxidative activity is present in safflower oil. We have reported that CS inhibits proinflammatory cytokine generation from human mono-cytes in vitro. As reactive oxygen species (ROS) affect cell proliferation, in this study the effect of CS on the proliferation of various cell types was examined. CS augments the proliferation of normal human and mouse fibroblast cells. The cells continue to proliferate in the presence of CS and form a transformed cell-like focus without transformation. CS, however, does not augment the proliferation of other cell types, either normal or tumor cells. CS augments the proliferation of fibroblasts in synergy with basic fibroblast growth factor (bFGF) or epidermal growth factor (EGF), but not with acidic FGF(aFGF) or platelet-derived growth factor (PDGF). This study using synthesized derivatives of CS reveals that the growth-promoting activity is not due to antioxidative activity. These findings indicate that CS is a natural compound with unique growth-promoting activity for fibroblasts [ABSTRACT FROM AUTHOR] |
