Inhibitory effect of artesunate on human esophageal carcinoma cells and the possible mechanism / 中国肿瘤生物治疗杂志

ABSTRACT

Objective: To explore the inhibitory effect of artesunate(Art)on human esophageal carcinoma cells and to study the related mechanism.Methods: Nude mice were inoculated with Eca109 cells subcutaneously on the left upper limbs to establish esophageal carcinoma model.The model mice were divided into 5 groups first group received 100 mg/kg Art,second group 200 mg/kg Art,third group 300 mg/kg Art,forth group 3 mg/kg cisplatin(DDP),and the fifth group received normal saline.Mass and volume changes of transplant tumors in different groups were observed.Flow cytometry was used to detect the cell cycle,apoptosis,and the expression of CDC25A protein,Smad3 protein and TGF-?protein in the transplanted tumors in mouse model.RT-PCR was used to detect the expression of CDC25A,Smad3 and TGF-?mRNA in the transplanted tumors.Results: Nude mouse model bearing human esophageal carcinoma was success- fully created.Compared with the control group,the volume and mass of transplant tumors in Art groups were significantly smaller(P
