摘要
目的: 探讨环氧合酶-2 (COX-2)和C-met蛋白在胃黏膜癌变过程中的变化规律及其意义.方法:采用Envision法,用20例慢性浅表性胃炎作为对照组,对38例慢性萎缩性胃炎伴肠上皮化生、38例肠化伴异型增生和76例胃腺癌标本,分别检测COX-2和C-met蛋白的表达情况,并分析其间的相关性.结果: C-met蛋白在慢性浅表性胃炎组的表达低于其他胃黏膜病变组织;从非萎缩性胃炎胃黏膜组织→肠化生→异型增生→胃癌,COX-2的表达逐渐增高.COX-2与C-met蛋白的表达呈正相关.结论: 细胞增殖和凋亡相关因子C-met蛋白与COX-2表达异常在胃黏膜癌变过程中发挥重要作用.
Objective: To investigate the expression and significance of cyclooxygenase-2 (COX-2) and C-met protein in the carcinogenesis of gastric mucosa. Methods: Twenty chronic superficial gastritis, 38 chronic atrophic gastritis with intestinal metaplasia, 38 intestinal metaplasia with dysplasia and 76 gastric cancer were collected. The expression of COX-2 and C-met protein in those tissues was determined by Envision irnmunohistochemieal technique, and the relationship between COX-2 and C-met was analyzed. The results were analysed by SPSS 13.0. Results: The expression of C-met protein in normal gastric mucosa was the lowest among the various gastritis from the non-atrophic gastric mucosa, dysplasia to gastric cancer. There was a positive correlation between the expression of COX-2 and C-met protein. Conclusion: COX-2 and C-met protein may play an important role in the carcinogenesis of gastric mucosa.
