Objective: To investigate the inhibitory effect and mechanisms of Shenqi Yiliu decoction(Yi Liu decoction) medicated serum on proliferation and metastasis of gastric cancer cell line MKN-45. Method:Methyl thiazolyl tetrazolium(MTT) was employed to test the viability of gastric cancer cell lines MKN-45. Transwell test and scratch test were used to detect the invasion and metastasis abilities. Real-time PCR technique was used to detect the expression of cyclooxygenase-2(COX-2) and phosphatase and tensin homol...
