中文摘要: |
目的:研究胃癌腺癌(gastric adenocarcinoma, GAC)中组胺H4 受体的表达水平及其临床意义。方法:60 例GAC 组织(病例
组)与配对癌旁组织(adjacent normal tissue, ANT)中应用免疫组织化学技术检测组胺H4 受体的表达,应用实时荧光定量RT-PCR
方法检测组胺H4 受体mRNA 的表达,统计分析组胺H4 受体表达与临床病理特征之间的关系。结果:①胃腺癌组织中组胺H4
受体蛋白的阳性表达率(11.7%)显著低于癌旁正常组织(96.7%)。②胃腺癌组织中组胺H4 受体mRNA 水平较癌旁组织明显降低
(p<0.001)。③组胺H4 受体蛋白和mRNA 表达异常和肿瘤的病理分级有相关性(p=0.0027 和p=0.0011),也与有无胃周淋巴结转
移有关(p<0.001 和p=0.0049)。结论:组胺H4 受体在胃腺癌组织有表达异常,表达量与病理分期相关。组胺H4 受体表达异常和
组胺水平紊乱可能在胃癌发生发展过程中有重要作用。 |

Abjective: To investigate the expression level of HRH4 in gastric adenocarcinoma (GAC) and its clinical significance.
Methods: The protein and mRNA level of HRH4 was examined in tissues from 60 patients with GAC by SP immunohistochemistry and
real-time PCR compared with adjacent normal tissues (ANT). Results:①The positive expression rate of HRH4 protein in GACs (11.7%)
was significantly lower than that in ANTs(96.7%,P<0.001).②The average mRNA level in patients with was much lower than those in
adjacent tissues. ③The positive expression rate of HRH4 protein and HRH4 mRNA in stage T3~T4 (2.6% and 5.1%) was significantly
lower than that in stage T1~T2 (28.6% and 38.1%, P<0.05). Conclusion: The expression of HRH4 gene is reduced significantly in GAC
tissues and is correlated with TNM stage. Abnormally expressed HRH4 and histamine might play a role in the progression of GAC. |
