    摘要: A set of isogenic cell lines, which includes a first population of cells that express only a wild type β-catenin polypeptide and at least a second population of cells that express only an activated β-catenin polypeptide, is provided. A set of isogenic cells, including a first population of cells that are null for β-catenin expression, and at least a second population of cells that express a wild type β-catenin polypeptide that functions as an activated β-catenin polypeptide in the cells, also is provided. In addition, a recombinant nucleic acid molecule, which includes at least a first linear polynucleotide that is flanked at each end by nucleotide sequences of a β-catenin gene is provided, as is a method of using the recombinant nucleic acid molecule to produce a set of isogenic cell lines as defined above. Also provide is a method of using the set of isogenic cell lines to identify a therapeutic agent that allows selective killing of cells expressing an activated β-catenin polypeptide, but not cells expressing a wild type β-catenin polypeptide is provided.

    摘要翻译: 提供了一组等基因细胞系,其包括仅表达野生型β-连环蛋白多肽的细胞的第一群和至少仅表达活化的β-连环蛋白多肽的第二细胞群。 一组等位基因细胞,包括对于β-连环蛋白表达无效的第一个细胞群,以及至少第二个表达野生型β-连环蛋白多肽的第二细胞群,其在细胞中用作活化的β-连环蛋白多肽 ,也被提供。 此外,提供了重组核酸分子,其包括至少第一线性多核苷酸,其每端末端具有β-连环蛋白基因的核苷酸序列,正如使用重组核酸分子产生组的方法一样 的等位基因细胞系。 还提供使用该组等基因细胞系鉴定允许选择性杀死表达活化的β-连环蛋白多肽的细胞但不表达野生型β-连环蛋白多肽的细胞的治疗剂的方法。
