초록

본 연구에서는 3T3-L1 지방전구세포를 이용하여 Allium 속 식물의 하나인 참산부추(ASM) 메탄올 추출물의 ROS 생성 저해 및 지질 축적 억제 효과를 확인하고자 하였다. 먼저 ASM 메탄올 추출물 $100{\sim}2,000{\mu}g/mL$의 모든 농도에서 유의적인 DPPH 라디칼 소거능을 나타내었으며, 지방전구세포에 ASM 메탄올 추출물 $10{\sim}100{\mu}g/mL$를 처리하였을 때 세포 독성을 나타내지 않았다. 지방세포 내 ROS 관련 효소와 분화 관련 전사인자의 조절로 인한 중성지방 축적 저해 활성을 확인하기 위하여 지방전구세포를 분화 유도하면서 추출물을 농도별(10, 50, $100{\mu}g/mL$)로 처리하였다. 그 결과 ASM 메탄올 추출물은 대조군에 비해 ROS 생성량과 ROS 관련 효소인 G6PDH mRNA 발현을 농도 의존적으로 감소시켰다. 또한 ASM 메탄올 추출물에 의하여 지방세포 내 중성지방 축적량이 유의적으로 감소하였으며, 지방세포 분화에 관련된 전사인자인 SREBP1c, $PPAR{\gamma}$$C/EBP{\alpha}$ mRNA 발현도 유의적으로 감소하였다. 이상의 결과들로 볼 때 ASM 메탄올 추출물로 인한 ROS 생성 저해와 지질 축적 억제는 ROS 생성 및 ROS 관련 유전자의 발현감소로 인한 지방 생성 주요 전사인자의 유전자 발현 억제로 인한 것으로 보이며, ASM이 항비만 효과가 있는 천연물 소재로 개발 가능성이 있을 것으로 사료된다.
