Abstract
Matrix metalloproteinases (MMPs) induction and type I procollagen reduction in photoaging of the skin due to exposure to ultraviolet (UV) irradiation. Therefore, regulation of these genes has been suggested to be a useful tool to abolish skin aging. In this study, antioxidative plant ingredients used in traditional Chinese medicine, berberine (BBR) was investigated for their capacity to regulate MMP-1 and type I procollagen expression in human dermal fibroblasts. Our results showed that both basal and UV-induced MMP-1 expression was decreased by BBR. On the other hand, type I procollagen expression was dose-dependently increased by it. In addition, UV-induced reduction of type I procollagen expression is recovered by it. Therefore, we suggest that BBR may be a possible candidate for anti-skin aging agent.Entities:
