神经母细胞瘤中间变性淋巴瘤激酶基因改变
Experimental pathology(2014)
Abstract
目的:观察国内儿童散发性神经母细胞瘤( neuroblastoma, NB)中间变性淋巴瘤激酶( anaplastic lymphoma kinase, ALK)的表达,探讨其在NB发生、发展中的作用。方法应用荧光原位杂交法( fluorescence in situ hybridization, FISH)检测56例ALK蛋白异常表达的NB中ALK基因的表达。结果 FISH检测显示56例NB中ALK基因46例为正常,10例为异常,其中9例为ALK增多(16%),1例为扩增(1.8%)。结论 ALK基因是NB一个主要的易感基因,国内儿童ALK基因异常的发生率与国外文献报道相近,其有可能成为治疗NB的主要靶点之一。
