초록
본 연구 결과들을 바탕으로 도깨비부채 잎(RPL)은 GSK3β활성화를 통해 IκB-α를 인산화시켜 단백질 분해를 유도하고 Iκ B-α분해로 인해 p65 핵내 전이를 유도하여 NF-κB 신호전달을활성화?시킨다. 이러한 NF-κB 신호전달 활성화를 통해 대장암의 세포생육을 억제하는 것으로 추정된다. 본 결과는 도깨비부채 잎을 소재로 항암을 목적으로 한 천연치료제 및 대체보완소재 개발에 활용할 수 있다고 판단된다. 그러나 도깨비부채 잎의대장암에 대한 세포생육 억제와 작용기전의 정확한 관련성과세포생육 억제활성 물질 분석을 위해 추가적인 연구가 필요할것으로 사료된다.
Abstract
In this study, we evaluated the anti-cancer activity and potential molecular mechanism of 70% ethanol extracts of leaves from Rodgersia podophylla against human colorectal cancer cells, HCT116. RPL dose-dependently decreased the cell viability through RPL-induced apoptosis in HCT116 cells. RPL induced inactivation the nuclear factor κB(NF-κB) through blocking IκB-α degradtion and P65 nuclear accumulation. The inhibition of GSK3β by LiCl attenuated RP-L-mediated NF-κB signaling inactivation. In addition, RP-L induced GSK3β activation. Based on these findings, RPL may be a potential candidate for the development of chemopreventive or therapeutic agents for human colorectal cancer
