백화사설초 추출물의 인체 대장암 세포주에서 항암효능에 관한 연구 = Anti-Cancer Effects of Oldenlandia diffusa extract on WiDr human colorectal adenocarcinoma cells

다국어 초록 (Multilingual Abstract)

Objectives : The purpose of this study was to investigate the anti-cancer effects of Oldenlandia diffusa extract on WiDr human colorectal adenocarcinoma cells. Methods : We examined cell death by (3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide) MTT assay and the caspase 3 and 9 activity assay with Oldenlandia diffusa extract. To examine the inhibitory effects of Oldenlandia diffusa extract, we performed a cell cycle (sub-G1) analysis and mitochondrial membrane potential for the WiDr cells after 24 hours with Oldenlandia diffusa extract. Results : 1. Oldenlandia diffusa extract induced cell death in WiDr cells. 2. The sub-G1 peak was increased by Oldenlandia diffusa extract in WiDr cells. 3. Oldenlandia diffusa extract leads to increase the mitochondrial membrane depolarization in WiDr cells. 4. Oldenlandia diffusa extract increases caspase 3 and 9 activities in WiDr cells. 5. Oldenlandia diffusa extract combined with several anti-cancer drugs (paclitaxel, 5-fluorouracil, cisplatin, ectoposide, doxorubicin and docetaxel) markedly inhibited the growth of WiDr cells compared to Oldenlandia diffusa extract and anti-cancer drugs alone. Conclusions : Oldenlandia diffusa extract has an apoptotic role in human colorectal cancer cells and a potential role in developing therapeutic agents against colorectal cancer.
