[Problem] The present invention aims to elucidate a polynucleotide as a novel responsible gene for cancer and aims to thus provide a method for detecting the polynucleotide and a polypeptide encoded by the polynucleotide and a detection kit, a probe set, and a primer set for the detection. The present invention also aims to provide a pharmaceutical composition for treating cancer.
[Means for Solution] The method detects a fusion gene composed of a portion of an FGFR3 gene and a portion of a TACC3 gene or a fusion protein encoded by the fusion gene. The primer set, the probe set, or the detection kit comprises a sense primer and a probe set designed from the portion encoding FGFR3 and an antisense primer and a probe set designed from the portion encoding TACC3. Since an inhibitor of the polypeptide exhibits antitumor effect, a pharmaceutical composition for treating cancer which is positive for either the fusion gene or the polypeptide is provided.
[问题]本发明旨在阐明一种多核苷酸是癌症的新型责任
基因,因此旨在提供一种检测该多核苷酸和由该多核苷酸编码的
多肽的方法,以及用于检测的检测试剂盒、探针组和引物组。本发明还旨在提供一种治疗癌症的药物组合物。
[解决方法]该方法检测由 FGFR3
基因的一部分和 TACC3
基因的一部分组成的融合
基因或由该融合
基因编码的融合蛋白。引物组、探针组或检测试剂盒包括根据 FGFR3 编码部分设计的有义引物和探针组,以及根据 TACC3 编码部分设计的反义引物和探针组。由于该
多肽的
抑制剂具有抗肿瘤作用,因此提供了一种用于治疗癌症的药物组合物,该药物组合物对融合
基因或该
多肽均呈阳性反应。
