Abstract

In this study, we investigated the effects of Sedum sarmentosum extract on the expression of hyaluronan synthase (HAS) genes and hyaluronan (HA) production in HaCaT keratinocytes. We also assessed water content (electrical capacitance) and transepidermal water loss (TEWL) in human skin after topical treatment with Sedum sarmentosum extract. Sedum sarmentosum extract increased expression of HAS-2 and HAS-3 genes in HaCaT cells, when assayed by real-time reverse-transcriptase polymerase chain reactions (RT-PCR). Sedum sarmentosum extract induced HA production in HaCaT cells, when determined by enzyme-linked immunosorbent assay (ELISA). Finally, treatment of Sedum sarmentosum extract on human skin increased the skin hydration and decreased TEWL when measured using Corneometer and Tewameter. Our study suggests that Sedum sarmentosum extract should be a very useful cosmetic ingredient, as a skin moisturizer.

본 연구에서는 돌나물추출물이 각질형성세포에서 hyaluronan synthase (HAS) mRNA 발현과 hyaluronan (HA) 생성에 미치는 영향을 알아보았다. 또한 돌나물추출물이 가지는 인체 피부에서의 보습력 증진 효과를 평가하였다. 돌나물추출물 처리에 따른 각질형성세포에서의 HAS-1, -2, -3 mRNA 발현 변화는 semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR)을 통해 살펴보았고, HA의 생성량 변화는 enzyme-linked immunosorbent assay (ELISA)를 수행하여 확인하였다. 인체 피부에서의 수분함량 및 피부 수분 손실량에 미치는 영향은 Corneometer와 Tewameter를 이용하여 측정하였다. 그 결과, 돌나물추출물은 사람 각질형성세포의 HAS-2, -3 mRNA의 발현을 증가시켰고, HA의 생성량을 농도의존적으로 증가시킴을 확인하였다. 사람 피부에서는 수분 함량을 유지하는 효과가 우수하였으며, 표피 수분 손실량 또한 감소시켜 피부 보습제로서 매우 우수한 효과를 보였다 이상의 결과를 통해 돌나물은 피부에서 HA 생산을 촉진시키며, 피부 보습력을 증진시키는 화장품 소재로 이용될 수 있을 것으로 사료된다.
