摘要: 目的探讨6号染色体长臂的杂合性缺失(LOH)与膀胱肿瘤的关系。方法应用6q21区域附近D6S404、D6S434微卫星标志,以PCR-SSLP银染法对31例膀胱肿瘤患者的肿瘤组织进行杂合性缺失的研究。结果膀胱肿瘤组织D6S40 4LOH发生率为35.5%,D6S43 4LOH发生率为22.6%。结论6q21区域附近可能存在与膀胱肿瘤相关的肿瘤抑制基因。

Abstract: ObjectiveTo investigate the loss of heterozygosity (LOH) on 6q in bladder tumor.MethodsD6S404 and D6434 microsatellite markers near 6q21 were tested by PCR-SSLP-stain method on tumor DNA from 31 cases of bladder tumor.ResultsAmong these 31 cases of bladder tumor,LOH was detected in tumor tissues on site for D6S404 (35.5%) and D6S434(22.6%).ConclusionOne or more tumor suppressor gene near 6q21 maybe relevant for the development of bladder tumor.

Key words: bladder tumor, loss of heterozygosity (LOH), long arm of chromosome 6(6q)
