Abstract

Obesity is one of the metabolic diseases caused by excessive differentiation and accumulation of adipose tissue due to an imbalance between energy intake and consumption. In this study, we investigated the anti-obesity effect of SliMax, a natural-derived 6 compounds mixture, by using 3T3-L1 cells. As a result, SliMax showed the inhibitory effect on adipocyte differentiation through down-regulation of the PPARγ and C/EBPα expression, which are known to regulate the late adipogenesis stage. In the process of lipolysis on differentiated 3T3-L1 cells, SliMax accelerated decomposition of large-sized unilocular lipid droplet into numerous small-sized multilocular lipid droplets through up-regulation of the expression of lipolysis-related proteins ATGL and HSL. Finally, in order to confirm the effect of SliMax on induction of brown adipocyte, the expression of UCP-1 and the amount of mitochondria were confirmed by immunofluorescent staining, and as a result, SliMax increased the expression of UCP-1 and the amount of mitochondria in fat cells. Taken together, those results suggest that SliMax, a naturally-derived mixture, have a potential to be anti-obesity agent through exerting inhibitory effect on the formation of lipid droplet by suppression of adipogenesis and stimulation of lipolysis, and browning effect associated with generation of heat energy and energy consumption.

비만은 에너지의 섭취와 소비의 불균형으로 인해 지방조직이 과도하게 분화하여 과잉 축적이 되면서 발생하게 되는 대사질환 중 하나이다. 본 연구에서 저자들은 3T3-L1 지방세포를 이용해 천연 유래 6 종 혼합물인 SliMax의 항비만 효과를 확인하였다. 그 결과 SliMax는 지방분화 단계에서 후기 분화를 조절하는 것으로 알려진 PPARγ와 C/EBPα의 발현 억제를 통해 지방분화를 억제하는 결과를 보였다. 또한 지방세포 분화 유도 후 지방세포 분해 과정에서 SliMax는 지방분해 관련 단백질인 ATGL과 HSL 발현 증가를 통해 큰 사이즈의 단방성 지방구를 작은 사이즈의 수많은 다방성 지방구로 분해하였다. 마지막으로 갈색지방으로 유도하는 효능을 확인하기 위해 UCP-1의 발현과 미토콘드리아 양을 면역형광염색법으로 확인한 결과 SliMax가 지방세포의 UCP-1의 발현과 미토콘드리아 양을 증가시켰다. 결과를 종합해볼 때, 천연 유래 혼합물인 SliMax는 지방 분화억제와 지방분해 촉진을 통해 지방구의 형성을 억제하고, 열 생산과 에너지 소비와 관련된 갈색지방화 촉진 기능을 가져 항비만 소재로의 가능성을 가진다.
