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.
由于暴露于紫外线(UV)辐射,基质金属蛋白酶(MMPs)在皮肤光老化中被诱导,而I型前胶原减少。因此,调节这些基因被认为是消除皮肤老化的一种有用工具。在本研究中,对传统中药中使用的抗氧化植物成分黄连素(BBR)调节人皮肤成纤维细胞中MMP-1和I型前胶原表达的能力进行了研究。我们的结果表明,BBR可降低基础和UV诱导的MMP-1表达。另一方面,I型前胶原表达则呈剂量依赖性增加。此外,它还能恢复UV诱导的I型前胶原表达的降低。因此,我们认为BBR可能是一种抗皮肤老化剂的潜在候选物。
