This study was designed to investigate the mechanism of the synergistic anticancer effect of Astragalus membranaceus (AM) and Adenophora triphylla var. japonica (AT) in H1299 human lung carcinoma cells. A combined treatment of ethanol extract of AM (EAM) and AT (EAT) explosively increased the reacti...

Apoptosis의 특징은 무엇인가? | Apoptosis는 일정한 프로그램에 따라 세포가 능동적으로 죽는 과정으로서 세포막의 blebbing 현상, 세포질과 염색질의 응축, DNA의 절편화 등을 특징으로 한다. Necrosis가 일어난 세포는 팽창하여 터짐으로써 주변 조직에 염증을 일으키는 반면 apoptosis 가 일어난 세포는 식세포의 식작용에 의해 제거되므로 주위에 염증 반응을 일으키지 않는다17,18). | |
암세포에 활성산소종을 유발함으로써 항암활성을 가지는 천연물 성분에는 무엇이 있는가? | 특히 다양한 천연물 성분이 암세포에 활성산소종을 유발함으로써 항암활성을 가진다고 알려져 있다. 예를 들어 capsaicin은 췌장암세포에24), curcumin은 위암세포에25), phenethyl isothiocyanate은 만성골수성백혈병세포에26), piperine은 악성흑색종세포27), deguelin은 폐암세포에 각각 활성산소종을 유발하여 apoptosis를 일으킨다고 보고되어 있다28). 뿐만 아니라 활성산소종을 유발하는 천연물질들은 암세포의 세포주기조절과 전이 억제 및 기존 항암치료의 효과를 높임으로써 항암활성을 나타낸다29-31). | |
황기의 효능은 무엇인가? | 한의학적으로 폐암은 전신적인 正氣와 陰液 부족 등 虛證을 근본으로 痰飮과 瘀血이 생겨 형성되는 것으로 알려져 있으며, 실제 중의학에서는 폐암을 치료하는데 황기와 사삼을 주요약재로 한 益氣養陰法을 적극적으로 운용해왔다4,5). 황기와 사삼의 항암작용에 대한 전임상연구들을 살펴보면 황기는 면역증강과 신생 혈관억제를 통해 항암활성을 가지며6-10), 사삼은 암세포의 apoptosis 유도, 비장세포 증식유도 및 혈관신생억제 등을 통해 항암작용을 나타낸다11-15). 이에 본 저자는 인체폐암세포에서 황기와 사삼이 항암 시너지효과를 가지는지 여부를 조사하여 유의한 결과를 보고하였으나16), 그 기전은 명확히 밝혀지지 않았다. |
