Abstract: Objection To investigate the effect of evodiamine on proliferation of HCT-116 in balb/c nude mice, and to explore its possible mechanism. Methods HCT-116 cells were injected into the right armpit of 4 week old Balb/c nude mice, the feeding had been executed at the time of the diameter of the xenografted tumor reached 0.5 cm, at the dose of 3 mg/kg (Evo), body weight and tumor diameter had been tested every three days, and made the curve of body weight and tumor diameter of the mice. All the mice were sacrificed after 22 days of feeding, and harvested the xenografted tumors. The morphological difference of the two groups tumor were identified by HE staining, the expression of HDAC3, NF-κB and p53 protein were detected by IHC and Westernblot. Results Compared with the control groups, the volume and weight of the tumors in Evo groups were significantly lighter, and the body weight of the nude mice were heavier, The tumor cells in Evo groups were shrink, deeply staining nucelus and their abnormal mitoses were fewer, the expression of NF-κB and p53 were increased but HDAC3 was decreased in xenografted tumors treated with Evo (P<0.05). Conclusion Evo can affect the expression of NF-κB and p53 by down-regulating HDAC3, and inhibit the proliferation of HCT-116 cells line in vivo.
