초록

본 연구에서는 발아 검은 쌀로부터 분리한 올리고펩타이드($Oligosproutin^{(R)}$)의 피부 탄력 개선 효과에 대하여 연구하였다. 올리고펩타이드가 각질형성세포의 유전자 발현에 미치는 영향을 알아보고자 DNA microarray를 수행하였다. 각질형성세포에 올리고펩타이드를 처리하여 유전자의 발현이 2배 이상 증가하는 유전자는 745개이고, 2배 이상 감소하는 유전자는 1011개로 나타났다. 이 중 hyaluronan synthase 2 (HAS2)의 유전자 발현이 2배 이상 증가함을 확인하였다. 올리고펩타이드를 처리한 각질형성세포에서 세포활성 증가, HAS2 유전자 발현 증가, 세포내 항산화 효과를 확인하였다. 올리고펩타이드를 함유한 O/W 에멀젼을 이용한 임상실험에서 피부의 탄력 개선 효과를 확인하였다. 본 연구를 통하여 발아 검은 쌀로부터 분리한 올리고펩타이드는 피부 탄력 개선을 주는 항노화 화장품 개발에 응용될 수 있을 것이라 기대된다.

In this study, the effect of oligopeptide ($Oligosproutin^{(R)}$) from sprouted black rice was evaluated for possible improvement in skin elasticity. We examined the changes in gene expression on oligopeptide-treated HaCaT cells using DNA microarray analysis. As a result, oligopeptide treatment showed a differential expression ratio of more than 2-fold : 745 genes were activated and 1011 genes were repressed. One of the most interesting findings is a 2-fold increase in hyaluronan synthase 2 (HAS 2) gene expression by oligopeptide. We also found that oligopeptide increased cell proliferation, HAS2 mRNA expression and intracellular ROS scavenging activity in HaCaT cells. A human clinical study which oil-in-water emulsion with oligopeptide was topically applied showed significant increase in skin elasticity. These results suggest that the sprouted black rice oligopeptide ($Oligosproutin^{(R)}$) can be effective anti-aging ingredient for cosmetics.
