영문 초록

The production of matrix metalloproteinases (MMPs) by the UV irradiated skin fibroblast and the degradation of extracellular matrix (ECM) by these enzymes is known as one of the main reasons of photoaging. In this papers to inverttigate the relationship between aging and Selaginella tamariscina extract (STE), we investigated the effects of antioxidant and expression of UVA-induced MMP-1 in human dermal fibroblasts. STE was fecund to show scavenging activities of radicals and reactive owgen species (ROS) with the Icso values of 65.1 ㎍/ml against 1,1-diphenyl- 2-picrylhydrazyl(DPPH) radical and 40.9 ㎍/ml against superoxide radicals in the xanthine/xanthine oxidase system, respectively. UVA Induced MMP expression was reduced 75.5% by treatment with STE, and MMP-1 mRNA expression was reduced in a dose- dependent manner Therefore STE was able to significantly inhibition of MMP expression in protein and mRNA level. All these results suggested that STE may act as an anti- aging agent by antioxidation and reducing UVA-induced MMP-1 production.
