Immuno-chemical staining with SP method was conducted to detect the protein expression of E-cadherin and Vimentin in 44 lung cancer tissues. E-cadherin was highly expressed in all normal lung tissues, and Vimentin was lowly expressed in all normal lung tissues. The expression rate of E-cadherin and Vimentin was 40.9% and 25.0% in NSCLC cases. The expressions of E-cadherin and Vimentin were not associated with gender, age, histopathological grading, lymphatic metastasis or smoking status (P > 0.05). But they were associated with clinical stage (P < 0.05). In addition, a negative correlation between the E–cadherin and Vimentin was observed (Spearman’s r = ?0.397, p < 0.05). E-cadherin and Vimentin are involved in the transformation of epithelial cells into the mesenchymal cells, which play important role in the metastasis of lung cancer.展开更多

目的本研究通过分析上皮细胞-间质转型(Epithelial to mesenchymal transition,EMT)相关通路蛋白E-cadherin、vimentin、snail及NF-κB在胃癌淋巴转移组及无转移组中的表达情况,探讨EMT在胃癌淋巴转移中的可能作用。方法选取淋巴结转移...目的本研究通过分析上皮细胞-间质转型(Epithelial to mesenchymal transition,EMT)相关通路蛋白E-cadherin、vimentin、snail及NF-κB在胃癌淋巴转移组及无转移组中的表达情况,探讨EMT在胃癌淋巴转移中的可能作用。方法选取淋巴结转移者31例(有淋巴结转移组),无淋巴结转移者25例(无淋巴结转移组),取其癌组织,通过免疫组化方法检测E-cadherin、vimentin、snail及NF-κB在相关组织中的表达情况,并通过统计学分析两组间的表达差异。结果在胃癌组织中,有淋巴结转移组E-cadherin的表达明显低于无淋巴结转移组,而vimentin与其相反,有淋巴结转移组的表达明显高于无淋巴结转移组,两者比较均有统计学差异(P<0.05);同时有淋巴结转移组snail的表达明显低于无淋巴结转移组,NF-κB在有淋巴结转移组的表达明显高于无淋巴结转移组,两者比较均有统计学差异(P<0.05)。相关性分析提示E-cadherin的表达与NF-κB表达相关,而vimentin及snail的表达则与其无关。结论 E-cadherin及vimentin可能通过NF-κB及snail调节表达,通过EMT参与胃癌淋巴转移,其表达高低可以作为淋巴转移发生几率的预测,联合检测可作为重要的生物学指标,用于术前胃癌检测。展开更多
