The present invention provides a method for identifying a tumor - in a human individual or in an animal - that is susceptible to treatment with a TTK inhibitor, said method comprising: a] providing a sample of a tumor; b] determining the presence of a mutated CTNNB1 gene in said tumor sample, wherein said mutation is located in exon 3 of CTNNB1 and whereby the presence of a mutated CTNNB1 gene indicates that the tumor is susceptible to treatment with a TTK inhibitor. In an alternative aspect, step b] of the above defined method is replaced by the step of determining the presence of a mutated CTNNB1 protein in said tumor sample, wherein said mutation is located in exon 3 of CTNNB1 and whereby the presence of a mutated CTNNB1 protein indicates that the tumor is susceptible to treatment with a TTK inhibitor. In a further alternative, step b] comprises determining an altered expression of a CTNNB1 regulated gene, whereby an altered expression of a CTNNB1 regulated gene indicates that the tumor is susceptible to treatment with a TTK inhibitor.
本发明提供了一种用于识别易受TTK抑制剂治疗的人体或动物肿瘤的方法,所述方法包括:a] 提供肿瘤样本;b] 确定肿瘤样本中是否存在突变的CTNNB1基因,其中所述突变位于CTNNB1的第3外显子中,并且存在突变的CTNNB1基因表明肿瘤易受TTK抑制剂治疗。在另一种方面,上述定义方法的步骤b] 被替换为确定肿瘤样本中是否存在突变的CTNNB1蛋白,其中所述突变位于CTNNB1的第3外显子中,并且存在突变的CTNNB1蛋白表明肿瘤易受TTK抑制剂治疗。在进一步的替代方案中,步骤b] 包括确定CTNNB1调控基因的表达改变,其中CTNNB1调控基因的表达改变表明肿瘤易受TTK抑制剂治疗。
