融合基因已被确定为某些癌症中的染色体重排,如白血病、淋巴瘤和肉瘤。EML 4-ALK(EML 4:棘皮动物微管相关蛋白样4; ALK:间变性淋巴瘤激酶)融合基因已被鉴定为非小细胞肺癌(NSCLC)的癌基因。这项研究检查了这种融合转录本在胃肠道和乳腺癌中的存在。我们评估了104例肺癌病例和645例胃肠道癌和乳腺癌样本中EML 4-ALK转录本的表达。只有一个肺癌样本的EML 4-ALK融合转录检测呈阳性,而在555例胃肠道癌和90例乳腺癌病例中均未检测到。我们的数据表明EML 4-ALK融合转录本不存在于胃肠道癌或乳腺癌中,并且对NSCLC具有特异性。
Fusion genes have been identified as chromosomal rearrangements in certain cancers, such as leukaemia, lymphoma, and sarcoma. The EML4–ALK (EML4: echinoderm microtubule-associated-protein-like 4; ALK: anaplastic lymphoma kinase) fusion gene has been identified as an oncogene in non-small-cell lung cancer (NSCLC). This study examined the presence of this fusion transcript in gastrointestinal and breast cancers. We evaluated the expression of the EML4–ALK transcript in 104 lung cancer cases and in 645 gastrointestinal and breast cancer samples. Only one of the lung cancer samples tested positive for the EML4–ALK fusion transcript, whereas none were detected in 555 gastrointestinal and 90 breast cancer cases. Our data suggest that the EML4–ALK fusion transcript is not present in gastrointestinal or breast cancers and is specific to NSCLC.
