A STUDY ON THE TREATMENT OF GASTRIC CANCER BY CD GENE COMBINED WITH 5-FC IN VITRO AND IN VIVO

Objective: To study the killing effect of suicide gene CD on mouse gastric cancer. Methods: CD gene was transduced with the retroviral vector. The killing effect and bystander effect of CD gene on mouse gastric cancer cell line MFC were observed. The mouse gastric cancer model was used for in vivo study. The CD gene containing virus was injected into the tumors. The volumes of the tumors in every group were measured in time. Results: Significant killing effect and bystander effect were observed by CD gene in vitro, 70~80% cell death resulting from 20% of CD gene transduction. In vivo, CD/5-Fc caused tumor to diminution. Conclusion: CD/5-Fc system has significant killing effect on mouse gastric cancer
