摘要 目的通过检测芳香烃受体(aryl hydrocarbon receptor,AhR)在胃癌及其多阶段癌前病变组织中的表达,初步探索AhR在胃癌发生中的作用。方法采用Envision免疫组织化学检测慢性浅表性胃炎30例、慢性萎缩性胃炎30例、肠型化生30例、异型增生30例及胃癌70例组织中AhR在胞浆及胞核的表达。结果 AhR阳性信号位于细胞核及胞浆。AhR胞浆阳性表达率从慢性浅表性胃炎、慢性萎缩性胃炎、肠型化生、异型增生到胃癌组织呈递增趋势;与慢性浅表性胃炎(33.3%)、慢性萎缩性胃炎(53.3%)及肠型化生组织(56.7%)比较,异型增生组织和胃癌组织AhR核阳性表达率显著升高(P<0.05),分别为83.3%(25/30)和94.3%(66/70)。结论AhR在胃癌及其多阶段癌前病变组织中表达逐渐上调,提示AhR与胃癌的发生密切相关。
