A method for identifying a tumor that is susceptible to treatment with a TTK inhibitor, including: a) providing a sample of a tumor; b) determining the presence of a mutated CTNNB1 gene in the sample, wherein the mutation is located in exon 3 of CTNNB1 and the presence of a mutated CTNNB1 gene indicates the tumor is susceptible to treatment with a TTK inhibitor. Alternatively, step b) is replaced by the step of determining the presence of a mutated CTNNB1 protein in the sample, wherein the mutation is located in exon 3 of CTNNB1 and the presence of a mutated CTNNB1 protein indicates the tumor is susceptible to treatment with a TTK inhibitor. In a further alternative, step b) includes determining an altered expression of a CTNNB1 regulated gene, whereby an altered expression of a CTNNB1 regulated gene indicates the tumor is susceptible to treatment with a TTK inhibitor.
一种鉴定易受
TTK
抑制剂治疗的肿瘤的方法,包括:a)提供肿瘤样本;b)确定样本中是否存在突变的CTNNB1
基因,其中突变位于CTNNB1的第3外显子,突变的CTNNB1
基因的存在表明肿瘤易受
TTK
抑制剂的治疗。或者,将步骤 b) 替换为确定样本中是否存在突变的 CTNNB1 蛋白,其中突变位于 CTNNB1 的第 3 号外显子,且突变的 CTNNB1 蛋白的存在表明肿瘤易受
TTK
抑制剂的治疗。在另一种选择中,步骤 b) 包括确定 CTNNB1 受控
基因表达的改变,其中 CTNNB1 受控
基因表达的改变表明肿瘤易受
TTK
抑制剂的治疗。
