Emodin inhibits CKII activity with IC50 of 2 M, which is two to thre
4、e orders ofmagnitude lower than those against the other kinases. Enzyme kinetic assays show that Emodin inhibits CKIIactivity as acompetitive inhibitor against ATP with Ki of 7.2 M 1. Emodin is a broad-spectrum inhibitoryagent of cancer cells, including leukemia, lung cancer, human tongue squamous c
5、ancer, colon cancer,gallbladder cancer, pancreatic cancer, breast cancer, human cervical cancer and hepatic carcinoma cells.Emodin inhibits A549, HepG2, OVCAR-3, HeLa and Madin-Darby Canine Kidney (MDCK) cells with IC50 of19.54, 12.79, 25.82, 12.14 and 5.81 g/mL. The anticancer mechanisms of Emodin
6、are involved in manybiological pathways, such as casein kinase II and ERK1/2 2. Emodin is applied as a Reactive oxygenspecies (ROS) generator in combination with cisplatin in T24 and J82 human bladder cancer cells. Emodinkills T24 and J82 cells in the dose-dependent and time-dependent manner, and it
7、 is less toxic to HCV-29cells. The concentration of 20 and 15 M is selected as appropriate doses for investigating chemotherapeuticsensitivity of T24 and J82 cells at 24 h, respectively 3.体内研究 Mice treated with Emodin (50 mg/kg) and Cisplatin (1 mg/kg) have significantly smaller tumors than thosefro
8、m the other groups. In addition, no notable differences on the body weight loss are observed amonggroups and no obvious necrosis and abnormity are observed in the sections of liver, kidney and heart. Theseresults demonstrate that Emodin/cisplatin co-treatment can significantly suppress tumor growth
9、in vivo withno distinct side effects. Consistent with in vitro experiment, TUNEL assay shows that Emodin/cisplatincombination significantly increased cell apoptosis in xenograft tumors. Emodin/Cisplatin co-treatment groupalso has lower MRP1 expression than the other groups 3.PROTOCOLCell Assay 3 The

Cells are seeded in 96-well plates with 2104 cells per wel
11、l. Thecells are incubated with Emodin for 24 h at different concentrations (0, 5, 10, 20, 30, 40, 50, 60, 70 M) andchose the critical concentration (20 M) treated with cells for 0, 6, 12, 24, 48, 72, 96 h. The cells areincubated with cisplatin for 24 h at different concentrations (0, 0.5, 1.0, 1.5,
12、2.0, 2.5, 3.0 g/mL). MTT assayis used to analyze the cell viability. Cells are treated with drugs for 24 h and apoptotic rates are assessedwith flow cytometry using AnnexinV-fluorescein isothiocyanate (AnnexinV-FITC)/propidium iodide (PI) kit.Samples are prepared according to the manufacturers instr
