型胶原蛋白基因在反流性食管炎、Barrett食管及食管腺癌中的表达
2012
Overview
目的探讨反流性食管炎、Barrett食管及食管腺癌黏膜组织中Ⅰ型胶原蛋白(COL1A1)基因mRNA的表达水平及意义。方法经胃镜取材,采用荧光定量PCR方法检测反流性食管炎、Barrett食管、食管腺癌组织中COL1A1基因mRNA的表达水平。结果 COL1A1mRNA在正常组和反流性食管炎阴性组食管黏膜中呈低表达(0.154±0.119,0.152±0.105),在Barrett食管与食管腺癌食管黏膜中呈明显的高表达(0.396±0.170,0.726±0.561)。并且在从正常→反流性食管炎→Barrett食管→食管腺癌的发生、发展过程中,COL1A1mRNA的表达呈现渐进性增强,并与病期有关。结论 COL1A1基因的异常表达与反流性食管炎、Barrett食管和食管腺癌的发生、发展密切相关;COL1A1mRNA的表达水平可用作监测Barrett食管和食管腺癌早期发生及干预治疗效果的有用指标。
