The effects of COE on the expression of VEGF and CECs of Hepal-6 tumor bearing mice / 国际中医中药杂志

ABSTRACT

Objective To study the effects of Celastrus orbiculatus extracts (COE) on the expression of VEGF and CECs of Hepal-6 tumor bearing mice.Methods Animal Models of Hepal-6 portability liver tumor bearing mice were established and randomly assigned to six groups (eight mice per group) as followsuntreated control group,solvent vehicle control (DMSO) group,physiological saline control group,cisplatin-treated group,and different dosages COE-treated groups (40 mg/kg,20 mg/kg,10 mg/kg).To approach the effects of COE on the expression of VEGF and CECs in Hepal-6 toumor bearing mice.Results The ELISA and flow cytometer showed that COE could significantly inhibit the expression of VEGF(45.24±21.36) pg/ml and CECs (0.83 ± 0.10) ％ compared with the physiological saline control group (P＜ 0.01 ) with the dose of 20mg/kg.Conclusion COE could significantly down-regulate the expression of VEGF and CECs.It may be related with the effect of COE in inhibiting angiogenesis of tumor.
