Abstract

This study was performed to promote the effective utilization of edible marine resources and to develop functional food material from edible marine resource extracts for inhibiting lipid accumulation in liver. Edible marine resource extracts (ME) were prepared by hot water (MWE) and 80% ethanolic (MEE), and both the MWE and MEE extracts were assessed as to their cell cytotoxicity, and Oil Red O staining. Results demonstrated that ME showed no cytotoxic effects. However, treatment with MEE in the concentration of 1000, 500, and 250 ${\mu}g/mL$ significantly inhibited the lipid accumulation in HepG2 cells compared to MWE. Especially, among the 80% ethanolic extracts, Pagrus major, Larimichthys polyactis, Clupea pallasii, Octopus minor, Enteroctopus dofleini, Styela clava, dried sea mustard, and Enteromorpha intestinalis showed greater lipid accumulation inhibitory activity than the others.

수산물 추출물로부터 간세포내 지질축적억제효과 추출물의 탐색을 통해 지방간 형성 억제 활성물질을 밝힐 목적으로, 각 48종의 수산물 추출물의 사람 간암세포유래인 HepG2 세포주에서의 중성지질축적억제 효과를 조사하였다. 그 결과, 18개의 추출물에서 유의적인 지질축적억제효과를 보였고, 그 중 Pagrus major, Octopus minor, Enteroctopus dofleini, Undaria pinnatifida Sporophyll, Styela clava, Enteromorpha intenstinalis 등 6개의 추출물이 유효한 효과가 있음을 관찰하였다. 이상의 결과를 바탕으로 지질대사에 관여하는 단백질들의 발현 정도를 조사하고, 활성물질의 분리 및 정제 등에 관한 연구와 지방간 형성 억제 효과에 대한 기전 연구가 진행되어야 할 것으로 사료된다.
