Abstract
항독성 물질(파이토알렉신) 중 하나인 resveratrol(trans-3,4',5,-trihydroxystilbene)은 특정 암세포의 성장을 조절할 수 있다고 보고되어져 왔다. 그러나 구강암과 관련된 resveratrol에 관한 자료는 거의 없다. 따라서 본 연구에서는 사람 구강편평세포암종 KB 세포주를 이용하여 resveratrol의 구강암세포 성장억제에 미치는 효과와 세포성장 억제기전을 분석하였다.
본 연구에서 resveratrol에 의한 구강암세포 성장억제와 그 기전을 조사하기 위해, KB 세포주에서 resveratrol을 이용하여 MTT 분석, DNA fragmentation 분석, immunoblotting 및 caspase 활성분석 등을 시행하였다.
사람 구강편평세포암종 KB 세포주에서 resveratrol은 구강암 세포주의 성장을 시간과 농도에 의존적으로 억제하였다. KB 세포에서 resveratrol은 DNA fragmentation을 유도하였다. KB 세포에 resveratrol을 처리한 실험군에서 procaspase-3, procasapse-7 및 procaspase-9의 proteolytic cleavage 현상을 확인할 수 있었다. KB 세포에 resveratrol을 처리한 실험군에서 caspase-3/-7의 활성화를 확인할 수 있었다.
본 연구의 결과로 resveratrol은 사람 구강편평세포암종 KB 세포주의 apoptosis를 유도하여 구강암세포 성장을 억제시키는 것으로 사료된다. 또한 본 연구의 결과로, resveratrol을 이용한 구강암세포의 성장억제에 관한 하나의 방향을 제시할 수 있을 것으로 사료된다.

중심어: Resveratrol, 세포사, Apoptosis, 항암치료제, 구강암|Resveratrol (trans-3,4',5,-trihydroxystilbene), a phytoalexin that is present in grape skin and red wine, suppresses many types of cancers by regulating cell proliferation and apoptosis through a variety of mechanisms. However, resveratrol effects on oral cancer are not clearly established. The main goal of this study was to investigate the effect of resveratrol on cell growth and apoptosis induction in human oral cancer cells.

To determine the effect of resveratrol on cell growth and apoptosis induction in human oral cancer cells, it was examined by inhibition of cell growth (MTT assay), DNA fragmentation analysis, immunoblotting and determination of caspase activation in KB human oral squamous cell carcinoma. The results are as follows.

1. Treatment of resveratrol induced the inhibition of cell growth depended on the resveratrol treatment time and concentration in KB cells.
2. Treatment of resveratrol induced the formation of DNA ladder in a time- dependent manner in KB cells.
3. Resveratrol promoted proteolytic cleavages of procaspase-3 and procaspase-7 with the increases in the amount of cleaved caspase-3 and caspase-7.
4. The proteolytic processing of caspase-9 was increased by resveratrol treatment in KB cells.
5. Activation of caspase-3 and -7 was detected in living KB cells by fluorescence microscopy.

These results suggest that the resveratrol can induce the suppression of cell growth and cell apoptosis in KB human oral squamous cell carcinoma, and that it may have potential properties for anti-cancer drug discovery.
