摘要: 摘要: 目的 考察临床乳腺癌病理组织中 miR-100 和 Wnt 通路关键因子卷曲蛋白 (FZD) -8 表达之间的关系,并分析 miR-100 表达与乳腺癌患者淋巴结转移的关系。方法 选取中国医科大学附属第一医院乳腺外科术后的 50 例乳腺癌患者, 通过原位杂交检测乳腺癌患者病理组织及其配对的癌旁组织中 miR-100 的表达; 免疫组化检测 2 种组织中FZD-8的表达; 比较有无淋巴结转移患者癌组织中miR-100表达情况, 分析乳腺癌组织miR-100与FZD-8 表达的相关性。结果 miR-100 在乳腺癌组织中的表达明显低于其配对的癌旁组织[2.00 (1.00, 3.00)vs. 6.00 (3.50, 8.00) ]; 有淋巴结转移者癌组织中 miR-100 低表达[1.50 (1.00, 2.75)vs. 3.00 (2.00, 4.00) ]; 与癌旁组织相比, FZD-8 在乳腺癌组织中高表达[8.00 (6.00, 9.00)vs. 6.00 (3.75, 9.00) ], 且其表达水平与 miR-100 的表达呈负相关 (rs=-0.592, P < 0.001)。结论 miR-100作为抑癌 miRNA 参与乳腺癌转移的调节, 可能与其调控 FZD-8的表达有关。

Abstract: Abstract: Objective To evaluate the expression and relationship of miR-100 and FZD-8, one of the major compo⁃ nents of Wnt signaling pathway, and the correlation of their expressions with lymph node metastasis in patients with breast cancer. Methods The expression of miR-100 was determined in 50 samples of human breast cancer tissues and adjacent normal tissues by in situ hybridization. The correlation of miR-100 expression with lymph node metastasis was analyzed by Mann-Whitney U test. The expression of FZD-8 was measured in 50 samples of human breast cancer tissues and adjacent normal tissues by immunohistochemistry. The correlation of the miR-100 expression with the protein expression of FZD-8 was evaluated by Pearson rank analysis. Results The expression of miR-100 was significantly lower in human breast can⁃ cer tissues than that in adjacent normal breast tissues [2.00 (1.00, 3.00) vs. 6.00 (3.50, 8.00)]. The miR-100 expression was lower in patients with lymph node metastasis than that in patients without lymph node metastasis [1.50 (1.00, 2.75) vs. 3.00 (2.00, 4.00)]. The expression of FZD-8 was significantly higher in human breast cancer tissues than that in adjacent normal breast tissues [8.00 (6.00, 9.00) vs. 6.00 (3.75, 9.00)]. The miR-100 expression was negatively correlated with the FZD-8 pro⁃ tein expression in human breast cancer tissues (rs=-0.592, P < 0.001). Conclusion The miR-100, as an anti-metastasis- miRNA, may involve in the metastasis of breast cancer, which may be related with the regulation of the expression of FZD-8.
