초록
본 연구는 회향종자 물 추출물이 비만과 관련된 지질대사를 조절하는 효소들 가운데 lipoprotein lipase(LPL), acyl-CoA synthetase(ACS), hormone sensitive lipase (HSL)의 활성에 미치는 효과를 알아보았다. 정상 마우스에서 회향종자 물 추출물의 LPL 활성은 최고 21.9% 억제되었고, ACS와 HSL의 효소 활성은 각각 151.8%, 174.0% 증가되었다. 고지방식이 유도 비만 마우스에서 LPL은 12.0% 활성이 억제되었으며, ACS와 HSL은 742.0%, 134.4% 활성이 증가하였다. 결과적으로 회향종자 물 추출물이 효과적으로 세포내로 지방산의 유입을 억제하며, 유입된 지방산을 에너지원으로 사용하는 대사과정을 활성화시킴으로서 항비만 효능을 갖는다는 것을 추정할 수 있다.
Abstract
This study was carried out to estimate beneficial effects of Foeniculi fructus water extract on activities of key enzymes such as lipoprotein lipase (LPL), acyl-CoA synthetase (ACS), and hormone sensitive lipase (HSL) on lipid metabolism related with obesity. LPL and ACS were extracted from the epididymal adipose tissue and liver of C57BL/6J normal and obese mouse. Foeniculi fructus water extract treatment significantly reduced the activity of normal and obese LPL. When 100 ppm of Foeniculi fructus water extracts were tested, they decreased obese LPL activity by 12.0%. Foeniculi fructus water extract activated obese ACS activity by 7-fold compared with control at 1,000 ppm concentration. Expression of HSL mRNA was increased in Foeniculi fructus water extracts treated cells compared with non treated cells. All things considered, Foeniculi fructus water extract efficiently inhibits the influx of fatty acid into the cell, and activates metabolic process that uses fatty acids flowing as an energy source. Thus, it suggest that Foeniculi fructus water extract may have great potential as a novel anti-obesity agent.
