Rat glioma cell C6 was infected by the deficiency recombinant retrovirus (named C6TK). The sensitivity of C6TK cells to GCV or ACV increased 450 or 10 times than that of C6 cells respectively. Rat C6 glioma model was successfully built, and SD rats inoculated intracerebrally C6TK cells had normal gliomas. The average survival periods of the rats were about 15 days. However, after treated with ACV, the growth of C6TK tumors obviously regressed, and the survival periods extended to 57.8±8.1 days, especially in rats injected with mixed PA317TK and C6 cells or in situ PA317TK cells, which the tumors nearly disappeared after ACV administration and the survival periods extended to over 120 or 71.4±36.1 days respectively, P＜0.001.

结果：构建了带有HSV-tk基因的反转录病毒载体GINaTK，应用脂质体转移方法将GINaTK导入反转录病毒包装细胞PA317，成为产病毒细胞PA317TK，用带有HSV-tk基因的复制缺陷型反转录病毒感染C6细胞，命名为C6TK细胞，对GCV和ACV的敏感性分别高于亲本450倍和10倍；成功地建立了大鼠脑胶质瘤模型，并证实转染细胞C6TK的成瘤效应未改变，存活期约为15天；而经ACV治疗后，含有C6TK细胞的肿瘤生长明显被抑制，大鼠生存期延长为57.8±8.07天，尤其是采用PA317TK细胞混和治疗组和原位治疗组，肿瘤基本消失，大鼠生存期显著延长，混和治疗组存活120天以上，原位治疗组存活至71.4±36.1天。t检验，P值均小于0.001。

These variations may have some effect on gene structures and gene expression, and then contribute to intraspecific phenotypic diversities.

在物理图提供的序列基础上，对于籼粳稻两个主要栽培稻亚种进行了比较基因组分析，在2.3Mb对应区段中发现了两个亚种在基因组成和顺序上存在的广泛的微共线性，两者之间的差异主要由插入/缺失和单核苷酸多态性造成，这些差异可能影响基因的结构和表达，从而对种间表型差异产生影响。

Knockout and knockdown animals and/or cells can be closely examined for changes in phenotype.
