摘要
AIM: To study the expression of trefoil factor 1 (TFF1) and TFF2 in precancerous condition and gastric cancer and to explore the relationship between TFFs and tumorigenesis, precancerous condition and gastric cancer. METHODS: The expression of TFF1 and TFF2 was immunohistochemically analyzed in paraffin-embedded samples from 140 patients including 35 cases of chronic superficial gastritis (CSG), 35 cases of gastric ulcer (GU), 35 cases of chronic atrophic gastritis (CAG) and 35 cases of gastric cancer (GC). RESULTS: TFF1 and TFF2 were located in cytoplasm of gastric mucous cells. In CSG, GU, CAG and GC, the level of TFF1 expression had a decreased tendency (P〈 0.05). The expression of TFF2 was higher in GU than in CSG, but the difference was not significant. The expression of TFF2 also had a decreased tendency in GU, CAG, and GC (P〈 0.05). CONCLUSION: The reduced expression of TFF1 and TFF2 in precancerous conditions and gastric cancer may be associated with the proliferation and malignant transformation of gastric mucosa. More investigations are needed to explore the mechanism of TFFs and the relationship between TFFs and gastric cancer.
瞄准:处于癌症前期的状况和胃的癌症学习翘摇因素 1 的表示(TFF1 ) 和 TFF2 并且探索在 TFF 和肿瘤发生之间的关系,癌症前期的状况和胃的癌症。方法:TFF1 和 TFF2 的表示是组织化学地包括 35 从 140 个病人在嵌入石蜡的样品分析的免疫长期的表面的胃炎(CSG ) 的盒子,胃溃疡(GU ) 的 35 个盒子,长期的萎缩性胃炎(CAG ) 的 35 个盒子和胃的癌症(GC ) 的 35 个盒子。结果:TFF1 和 TFF2 位于胃的粘液细胞的细胞质。在 CSG, GU, CAG 和 GC, TFF1 表示的水平有一个减少的趋势(P < 0.05 ) 。TFF2 的表示比在 CSG 在 GU 是更高的,但是差别不是重要的。TFF2 的表示也在 GU, CAG,和 GC 有一个减少的趋势(P < 0.05 ) 。结论:处于癌症前期的条件和胃的癌症的 TFF1 和 TFF2 的减少的表示可以与增长和胃粘膜的恶意的转变被联系。更多的调查被需要探索在 TFF 和胃的癌症之间的 TFF 和关系的机制。
