摘要: 本文主要研究了冰川水和白雪茶提取物对正常人真皮成纤维细胞的抗衰老作用及其潜在的机制。用冰川水和白雪茶提取物处理正常人真皮成纤维细胞,检测了不同处理对细胞活性、细胞外基质成分及其水解酶表达水平的影响。结果显示,冰川水和白雪茶提取物可以提高人真皮成纤维细胞的增殖活性和能量代谢水平,促进透明质酸和弹性蛋白的表达;此外,白雪茶提取物还可以促进I型胶原蛋白的表达和下调弹性蛋白酶的mRNA表达水平;两者共同作用时影响更显著。以上研究表明,冰川水和白雪茶提取物有延缓皮肤衰老的作用,作用机制与两者可增强成纤维细胞活力,提高外基质成分的表达水平并抑制部分成分的降解有关。

Abstract: The objective of this study was to investigate the anti-aging effects of glacier water and Thamnolia vermicularis extract (TVE) on human dermal fibroblasts (HDF)and their underlying mechanism.The HDF were treated by glacier water and TVE,and then the cell viability,the expression level of extracellular matrix components and corresponding hydrolytic enzymes were examined.The results revealed that both glacier water and TVE can promote the cell proliferation and energy metabolism level of HDF,as well as enhancing cellular content of hyaluronic acid and expression level of elastin.Besides,TVE also showed an ability to up-regulate the expression of collage I and down-regulate the mRNA expression of elastase.Their efficacy was much more obvious when combining glacier water and TVE together.The results suggested that glacier water and TVE had anti-aging effect on skin through enhancing the cellular activity of HDF and promoting expression of extracellular matrix components as well as inhibiting their degradation.
