ABSTRACT
Arctiin, a lignin isolated from Arctium lappa, exhibits a variety of biological effects, including antiviral, antiinflammatory, and antiproliferative actions, in mammalian cells. In a previous study, arctiin was demonstrated to induce procollagen type I synthesis and exhibited protective effects against ultraviolet B (UVB) radiation in normal human dermal fibroblasts (nHDFs). However, the underlying molecular mechanism of arctiinmediated collagen synthesis remains unknown. In the present study, the mechanism for increased expression of collagen type 1α 1 chain (COL1A1) mRNA in arctiininduced nHDFs was identified. The expression of microRNA378b (miR378b), downregulated by arctiin, was correlated with the expression of sirtuin6 (SIRT6) mRNA, a regulator of COL1A1 mRNA. Furthermore, it was revealed that arctiin protected the UVB radiationmediated decrease in COL1A1 mRNA expression, through the miR378b/SIRT6 signaling pathway. In conclusion, these results suggest that arctiin regulates COL1A1 through the miR378bSIRT6 axis.
