산수유 에탄올 추출물이 환경호르몬인 dioxin 및 bisphenol A(BPA)에 의해 유도된 인체 전립선 암세포인 RC58T/h/SA#4(prostate epithelial primary cancer cell lines)의 성장을 억제하는지를 조사하였다. 즉 산수유 에탄올 추출물을 10, 100, 300 및 $500{mu}g/mL$ 농도로 RC58T/h/SA#4에 처리했을 시 $500{mu}g/mL$ 농도 이상에서 높은 성장 억제율을 나타내었으며, dioxin과 bisphenol A를 다양한 농도로 처리한 결과 각각 1 nM, $0.1{mu}M$ 농도에서 가장 높은 전립선암세포 증식을 유도하였다. 한편 환경호르몬(dioxin, BPA)에 의해 RC58T/h/SA#4의 증식을 유도시킨 후 산수유 에탄올 추출물을 10, 100, 300 및 $500{mu}g/mL$ 농도로 처리한 결과 대조군에 비하여 산수유 에탄올 추출물 $500{mu}g/mL$ 농도에서 그 억제율이 가장 높았다.
Anti-proliferation effects of Corni fructus ethanol extracts were investigated in the RC58T/h/SA#4 cells treated with environmental hormones including dioxin and bisphenol A. The proliferation was decreased at the concentration over $500{mu}g/mL$ in the RC58T/h/SA#4 cells with ethanol extracts of various concentrations (1, 10, 100, 500, and $1000{mu}g/mL$). The environmental hormones such as dioxin and bisphenol A increased the growth of RC58T/h/SA#4 cells in the charcoal-treated FBS (cFBS) medium. The proliferation was the highest at 1 nM and $0.1{mu}M$ for the tested dioxin and bisphenol A concentration, respectively. Ethanol extracts showed inhibition of the proliferation in a dose-dependent manner at the tested concentrations (10, 100, 300, and $500{mu}g/mL$) in the RC58T/h/SA#4 cells treated with the environmental hormones. The anti-proliferation was the highest at $500{mu}g/mL$ concentration among the tested ethanol extracts.
