메리골드(Tagetes L.)와 카렌듈라(Calendula officinalis L.) 추출물이 인간 섬유아세포에서 콜라겐 생성 및 MMP-1 발현에 미치는 영향 = The Effects of Marigold(Tagetes L.) Extract and Calendula(Calendula officinalis L.) Extract on Collagen Growth and MMP-1 Expression in Human Dermal Fibroblasts

다국어 초록 (Multilingual Abstract)

To research the effects of marigold extract, which is used mixed with calendula extract, on collagen growth and MMP-1 expression in human fibroblast, we measured cytotoxicity, collagen growth and MMP-1 expression by using HDF cells. The result of measurement showed over 80% cell survival rate in 5 ~ 100 μg/mL concentration of marigold extract and calendula extract for HDF cells, which indicates there is no cytotoxicity. The result of measuring collagen synthetic abilities showed both types of extract had collagen synthetic ability increase dose dependently, by 25% in 100 μg/mL concentration of marigold extract, and by 7% in 100 μg/mL concentration of calendula extract. The result of experimenting the effect on MMP-1 expression showed that both types of extract suppress MMP-1 expression. The result of observing phosphorylation of p-JNK and p-ERK, which are known to be involved with MMP-1 expression, revealed that marigold extract effectively suppresses MMP-1 expression through signaling pathway of p-JNK and p-ERK. The above results confirm the wrinkle improvement effect of marigold extract, and furthermore, it can be used as a cosmetic ingredient for anti-aging.

카렌듈라 추출물과 혼용되어 불리고 있는 메리골드 추출물을 인간섬유아세포에서 콜라겐 생성과 MMP-1 발현에 미치는 영향을 알아보기 위하여 HDF세포를 이용하여 세포독성 및 콜라겐 생성과 MMP-1 발현을 측정하였다. 실험 결과, HDF세포에 대한 메리골드와 카렌듈라 추출물의 5 ~ 100 μg/mL 농도에서 80%이상의 세포 생존율을 나타내어 세포독성이 없었으며, 콜라겐 합성능 측정 결과, 두 추출물 모두 농도 의존적으로 콜라겐 생성능의 증가를 나타냈으며, 메리골드 추출물 100 μg/mL 농도에서 25%, 카렌듈라 추출물 100 μg/mL 농도에서 7% 콜라겐 생성능의 증가를 확인하였다. MMP-1 발현에 미치는 영향 실험 결과, 메리골드와 카렌듈라 추출물 모두 MMP-1 발현을 억제시키는 것을 확인하였고, MMP-1 발현에 관련 있다고 알려진 p-JNK와 p-ERK의 인산화를 관찰한 결과, 메리골드 추출물은 p-JNK와 p-ERK 신호전달 경로를 통화여 MMP-1 발현을 효과적으로 억제하는 것을 확인하였다. 이와 같은 결과를 통해 메리골드 추출물의 주름 개선 효능을 확인하였고, 나아가 항노화 효능을 가지는 화장품 원료로 활용 가능성을 확인하였다.
