摘要 目的:根据女性体细胞中两条X染色体上雄激素受体(AR)基因的长度多态性进行非放标克隆性检测,以探讨女性结肠增生性息肉的克隆组成。方法:用石蜡切片,HE染色后应用激光显微切割系统进行显微切割并收集目的组织,提取基因组DNA,经HhaⅠ消化后,巢式PCR扩增,变性聚丙烯酰胺凝胶电泳后银染显示单股DNA片段长度。结果:在49例结肠增生性息肉标本中,45例扩增成功,其中39例(86.67%)具有AR位点的多态性;在适于分析的37例中,14例(37.84%)显示AR位点长度多态性丢失,其余23例(62.16%)无多态性丢失。结论:大部分结肠增生性息肉属于多克隆性病变,是反应性增生;少部分是克隆性增生,可能已经属于真性肿瘤。 Objective:To demonstrate the clonality status of colorectal hyperplastic polyps using an assay based on inactivation mosaicism of the length-polymorphic X chromosomes at the androgen receptor(AR) locus.Methods: Proliferative epithelial component of the colorectal hyperplastic polyps was collected using microdissection from the routine sections stained with hematoxylin and eosin.Stroma component was also isolated from the same samples,and used for parallel controls.Genomic DNA was extracted,pretreated with H...
