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

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.體內(nèi)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

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,
