Conclusions the double suicide gene driven by KDR promoter has specific killing effect on KDR-expressing gastric tumor cells and venous endothelial cells in vitro.
结论KDR基因启动子可调控双自杀基因系统选择性杀伤表达KDR胃癌细胞及血管内皮细胞。
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).
之后，在罗斯福新政时期（1937-38），石油危机时期（1973-75）和双底衰退时期（1980-82），自杀率开始下降。
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.
结果单、双自杀基因均在GLC- 82细胞中稳定表达，双基因转染组对细胞增殖的杀伤及旁杀伤效应高于单基因组。
