层粘连蛋白受体和nm23蛋白在乳腺癌组织中的表达及其与间 …

探讨乳腺癌组织层粘连蛋白（ＬＮ）及其受体（ＬＮ－Ｒ）和ｎｍ２３蛋白的表达与间质微血管密度及肿瘤转移的关系。方法应用免疫组织化学ＬＳＡＢ方法检测７３例乳腺癌力ｎｍ２３蛋白的表达,在第Ⅷ因子相关抗原染色切片上检测其微血管密度（ＭＶＤ）。结果病理分级越高,乳腺癌ＬＮ表达程度越强,即病理Ⅰ级而ＬＮ分布Ⅲ级者为８．３％,病理和ＬＮ分布均Ⅲ级者为５８．８％,两者间差异有极显著意义。ＬＮ－Ｒ表达程度则与转移有关

The relationship between laminin-receptor and nm23 protein expression and its correlation with interstitial microvascular density and tumor metastasis in breast carcinoma

OBJECTIVE: To study the relationship between 67,000 laminin, laminin-receptor (LN-R) and nm23 protein expression, interstitial microvascular density (MVD) and tumor metastasis in breast carcinomas. METHODS: The expression of laminin (LN), LN-R, FVIIIRAg and nm23 protein were detected in 73 cases of breast carcinoma with immunohistochemical technique and analyzed. RESULTS: A significant difference in LN expression was found in breast carcinoma according to their pathological grade. A positive relation exists between LN-R expression and lymph node metastasis. A positive relationship exists between the degree of LN-R and MVD expression. A significant difference in lymph node metastasis cases exists between nm23 protein positive expression group and negative expression group. When the expression of nm23 protein was inhibited, the degree of LN-R, MVD expression increased and positively related with lymph node metastasis. CONCLUSION: LN-R expression enhancement, microvascular density increase and nm23 expression inhibition may be the reliable markers for predicting tumor metastasis and prognosis.
