Conclusions the doublesuicide gene driven by KDR promoter has specific killing effect on KDR-expressing gastric tumor cells and venous endothelial cells in vitro.

Since then, the suicide rate has been dropping, with much smaller increases at the end of Franklin D. Roosevelt's New Deal (1937-38), the oil crisis (1973-75) and the Double-Dip Recession (1980-82).
Results Double and single suicide gene transfer were both stably expressed in GLC-82 cells. The cytotoxic effects of co-expressed TK-CD genes were superior than that of the single gene.
