Abstract

The objective of this study was to investigate the anticancer effects of Acer tegmentosum M. extracts. HepG2 hepatocarcinoma cells were treated with ethanol, chloroform, ethylacetate, butanol, aqueous fraction and hot water extract. The antiproliferative effect was evaluated by trypan blue exclusion, MTT-based viability assay and morphology. The trypan blue test showed that anticancer effect of the A. tegmentosum M. extracts on HepG2 cells increased gradually in proportion to the increasing concentration of the fractions. The butanol fraction showed the highest anticancer activity against HepG2 cells (p<0.05). The MTT assay indicated that the growth inhibition by the butanol fraction was dose-dependent. These results suggest that A. tegmentosum M. has the potential to inhibit the growth of hepatocarcinoma cells.

본 연구는 간암세포 HepG2의 증식을 억제하고 세포 사멸을 유도하는 천연소재 발굴을 목적으로, 산겨릅나무 분획 추출물을 이용하여 간암세포 HepG2의 증식에 미치는 영향을 확인하였다. 간암세포의 생존율에 분획별 추출물이 미치는 영향을 알아보기 위하여 분획물을 24시간, 48시간 동안 농도별로 처리하여 살아있는 세포를 계수한 결과 24시간 처리 시 모든 분획에서 농도 의존적으로 유의하게 생존율이 감소하였으며 유기용매 분획물들이 수용성 용매 추출물보다 높은 생육 억제 활성을 보였다. 48시간 처리 시에도 같은 경향이 나타났으며 24시간에 비하여 세포 생존율이 비슷하거나 조금 더 감소하였다. MTT assay를 통한 세포 생존 억제율의 측정 결과 BuOH 분획물은 간암세포에 대해 농도 의존적으로 생존 억제율을 증가시켰다. 형광현미경을 이용한 세포형태 관찰에서는 BuOH 분획물의 농도 의존적으로 세포의 형태가 응축되고 무정형으로 세포사멸이 나타나 apoptotic cell의 전형적인 양상을 확인할 수 있었다. Hong 등(10)의 연구에서 산겨릅나무의 추출물 중 ethyl acetat와 butanol 분획에서 뛰어난 항산화성과 항지질과산화 활성이 있음을 밝힌 내용과 Shin 등(11)의 위암, 간암, 폐암 및 유방암 세포 등에서 암세포 생육억제효과의 보고와도 유사한 경향이 나타남을 알 수 있었다. 이상의 실험을 통해 산겨릅나무가 간암세포의 성장을 저해하는 효과가 있음을 확인할 수 있었으며 앞으로 식용 및 약용자원으로서 활용가능성이 높은 것으로 판단된다.
