Protective effects of galangin against HO/UVB-induced dermal fibroblast collagen degradation via hsa-microRNA-4535-mediated TGFβ/Smad signaling.

This study aimed to investigate the mechanism underlying the protective effects of galangin against HO/UVB-induced damage using and models of photodamage. Moreover, we identified the involvement of miRNA regulation in this process. The HO/UVB-treated HS68 human dermal fibroblasts and UVB-induced C57BL/6J nude mice were used as and models of photodamage.
