Abstract:
A method for inhibiting melanosome migration by using prohibitin siRNA(small interference RNA) is provided to inhibit expression of prohibitin in a melanin synthesis cell and uniformed distribution of melanosome in the melanin synthesis cell, so that the skin is whitened. The melanosome migration to the end of melanin synthesis cell is inhibited by administering prohibitin siRNA into the melanin synthesis cell, melan-a, thereby inhibiting binding of prohibitin to melanophilin as a melanosome vehicle and uniformed distribution of melanosome in the melanin synthesis cell.
Abstract:
A food composition for improving and preventing obesity is provided to promote a beta oxidation of fatty acids effectively, and prevent and reduce an accumulation of excessive fat. The food composition for improving and preventing obesity contains coumestrol, a coumesterol-containing natural materials or an extract thereof as an active component. The active component promotes expression of Carnitine Palmitoyl Transferase 1A gene to increase a beta oxidation of fatty acids. The food composition for improving and preventing obesity is formulated into drink, diet bar, chocolate, caramel, or confectionery. The coumestrol is contained in an amount of 0.02-10wt% based on the total composition.

본 발명은 진세노사이드 F1(20-O-β-D-글루코피라노실-20(S)-프로토파낙사트리올)과 EGCG((-)에피갈로카테킨-3-갈레이트)의 상승효과에 의한 용도에 관한 것으로, 더욱 상세하게는 상기 화합물들을 동시에 처리하는 것을 특징으로 하는, 자외선 조사로 유도되는 피부세포의 사멸을 방지하는 방법에 관한 것이다. 본 발명은 단독 처리시에는 효과가 없는 낮은 농도의 두 화합물을 혼합하여 처리함으로써 자외선 조사에 의해 유발되는 Bcl-2의 발현 감소를 효과적으로 억제하여 피부세포의 사멸을 방지하는 Bcl-2 발현 조절제로서의 용도를 제공한다. 또한, 암억제 유전자인 Rb 단백질의 탈인산화를 억제하여 안정화시킴으로써 자외선에 의한 피부세포의 손상을 방지하는 용도를 제공한다. 본 발명을 통해 단가가 높은 두 화합물을 낮은 농도(단독 사용시 각각 2.5배, 5배 농도 필요)로 사용함으로써 원료비를 낮추어 고기능성 제품을 보다 저렴한 가격에 공급할 수 있다.
Abstract:
PURPOSE: Provided is a controlling agent of Bcl-2 expression which characteristically contains ginsenoside F1(20-O-beta-D-glucopyranosyl-20(S)-protopanaxatriol) represented by the formula(1), as an active ingredient. It prevents apoptosis caused by radiating low doses of ultraviolet rays, while promoting apoptosis when radiating high doses of ultraviolet rays, therefore it removes the risk of cancers. CONSTITUTION: A controlling agent of the expression of Bcl-2 is characterized by containing ginsenoside F1(20-O-beta-D-glucopyranosyl-20(S)-protopanaxatriol), which is represented by the formula(1), as an active ingredient. It inhibits the decrease of Bcl-2 expression caused by radiating ultraviolet rays. Therefore, it prevents apoptosis by the radiation of low doses of ultraviolet rays, but promotes apoptosis by the radiation of high doses of ultraviolet rays.
