摘要 目的:探讨脆性组氨酸三联体基因(fragile histidine trail, FHIT)蛋白在38例溃疡性结肠炎(ulcerative colitis,UC)、25例Crohn’s病、11例UC相关性腺癌和13例正常对照组中的表达情况. 方法:标本常规石蜡包埋,采用免疫组化法检测FHIT在UC、Crohn’s病、UC相关性腺癌和正常对照组中的表达. 结果:38例UC中,25例FHIT蛋白表达阴性;25例Crohn’S 病中,19例表达阴性;11例UC相关性腺癌中,6例表达阴性.FHIT蛋白在UC和正常对照组(71.43%vs 7.69%, X2=18.80,P<0.01)、Crohn’s病和正常对照组(76% vs 7.69%,X2=18.88,P<0.01)、UC相关性腺癌和正常对照组(54.55%vs 7.69%,X2=7.75,P<0.05)间均有显著性差异;而在UC和UC相关性腺癌中无显著性差异(54.55%vs 71.43%,X2=0.05,P>0.05). 结论:FHIT蛋白在炎症性肠病(inflammatory bowel disease, IBD)和UC相关性腺癌中呈低表达或缺失,提示该基因可能与IBD和UC相关性腺癌发生有关.
