Abstract

Anti-proliferation effects of decursin from Angelica gigas Nakai were investigated in the MCF-7 cells treated with environmental hormones. The proliferation was decreased in a dose-dependent manner at the concentration over 20 ${\mu}g/mL$ in the MCF-7 cells treated with decursin of various concentrations. The environmental hormones such as $17{\beta}$-estradiol and bisphenol increased the growth of MCF-7 cells in the charcoal-treated FBS (cFBS) medium and the proliferation was the highest at 0.1 ${\mu}M$ among the tested hormone concentration. Decursin was predicted to inhibit the proliferation in a dose-dependent fashion at tested concentrations (1, 3, 10 or 30 ${\mu}g/mL$) in the MCF-7 cells added environmental hormones; however, the survival rate of the cells was lower than that of control cells that were not treated with decursin at 30 ${\mu}g/mL$ concentration. The chromatin condensation and apoptotic body were examined in the decursin treated cells cultured with the cFBS medium added environmental hormones. These results suggest that decursin decreased the proliferation through apoptosis in the MCF-7 cells added environmental hormones.

당귀로부터 분리한 decursin을 환경호르몬에 의해 증식을 유도한 인체 유방암세포(MCF-7)에 처리한 후 그 억제효과를 조사하였다. 인체 유방암세포주인 MCF-7은 20, 40, 60, 80 및 100 ${\mu}g/mL$ 농도로 decursin의 처리 시 20 ${\mu}g/mL$ 이상에서 농도 의존적으로 그 증식이 억제되었다. 호르몬이 제거된 배지로 배양한 세포에 0, 0.01, 0.1 및 1 ${\mu}M$의 농도로 환경 호르몬 $17{\beta}$-estradiol과 bisphenol을 처리한 결과 호르몬이 제거된 배지로 배양한 세포에 비해 세포의 증식을 유도하였으며, Yamada(21)와 본 실험 결과가 유사한 세포성장을 보여 암세포의 성장억제 효과를 측정하기 위한 환경호르몬의 농도를 0.1 ${\mu}M$로 하였다. 환경호르몬에 의해 증식이 유도된 MCF-7 세포에 당귀 메탄올추출물 및 decursin을 1, 3, 10 및 30 ${\mu}g/mL$ 농도로 처리한 결과 농도에 비례하여 세포의 증식을 억제하였으며, 10 ${\mu}g/mL$의 농도 이상에서는 대조구의 증식보다도 낮은 생존율을 나타내어 강한 세포독성을 나타내었다. 또한 hoechst 염색을 통하여 세포 핵의 변화를 알아본 결과 decursin 처리군에서 핵의 응축과 apoptic body가 관찰되어 decursin은 apoptosis를 유도함으로써 환경호르몬이 처리된 MCF-7 세포의 증식을 억제하는 것으로 판단된다. 이들 결과는 decursin이 환경호르몬에 의해 증식이 유도되는 MCF-7 세포의 성장을 apoptosis에 의해 억제한다는 것을 나타낸다.
