简介:背景:紫外线照射后p53依赖的对DNA损害的反应与p33^ING1b基因有关,近来报道20%的黑素瘤存在p33^ING1b基因突变。目的:分析作者收集的大量新鲜黑素瘤组织和黑素瘤细胞系中p33^ING1b的突变率。方法:通过单链构象多态分析和直接测序法筛查83例原发性黑素瘤和55株黑素瘤细胞系中p33^ING1b的突变。结果:与之前报道相比,作者发现所有黑素瘤中没有体细胞p33^ING1b的突变。分析其结果与以往发表的研究结果间的差异部分可能由于不慎扩增ING1假基因(INGX)和(或)一些标本污染了鼠ING1。结论:p33^ING1b突变在黑素瘤中很罕见。作者强调等位基因特异性引物设计的重要性,以避免假基因扩增,并认为证实遗传同一性和个体细胞系的起源物种很有必要。需进一步研究来阐明黑素瘤致癌机制中p33^ING1b的可能作用。
