    Expression levels of connexin 26 and NF-κB in primary lesion and metastatic lymph nodes of triple negative breast cancer, and its clinical significance

      摘要
    • 摘要:
      目的探讨缝隙连接蛋白26（connexin 26，Cx26）和核转录因子κB（nuclear factor κB，NF-κB）在三阴性乳腺癌（triple negative breast cancer，TNBC）病人原发灶和淋巴结转移灶中的表达及临床意义。
      方法回顾性收集经术后病理和分子分型确诊为TNBC的存档石蜡组织，原发灶共49例，其中无区域淋巴结转移者22例（A1组），有区域淋巴结转移者27例（A2组）；将27例淋巴结转移灶作为B组。应用免疫组织化学SP染色法，检测各组中Cx26和NF-κB的表达情况，并分析二者表达的相互关系及其与临床病理特征的相关性。
      结果原发灶中A2组Cx26和NF-κB阳性表达率均高于A1组（P < 0.01和P < 0.05）；转移灶B组Cx26和NF-κB阳性表达率均高于原发灶A1组（P < 0.01）。Cx26蛋白表达与TNBC病人绝经状态、淋巴结转移有关（P < 0.01），NF-κB表达与pTNM分期、淋巴结转移有关（P < 0.01和P < 0.05）。在淋巴结转移灶中，Cx26与NF-κB表达呈明显正相关关系（r=0.663，P < 0.01）。
      结论Cx26和NF-κB共同参与TNBC的浸润和转移，可作为预测TNBC转移复发及评估临床预后的有效指标。

       

      Abstract:
      ObjectiveTo investigate the expression levels of connexin 26(Cx26) and nuckar factor κB(NF-κB) in primary lesion and metastatic lymph nodes of triple negative breast cancer(TNBC), and its clinical significance.
      MethodsThe TNBC paraffin tissues diagnosed by postoperative pathology and molecular classification were collected.Forty-nine cases of primary lesions and 27 cases of lymph nodes metastatic lesions were divided into group A and group B, respectively.Group A included 22 cases without regional lymph node metastasis(group A1) and 27 cases with regional lymph node metastasis(group A2).The expression levels of Cx26 and NF-κB in all cases were examined using immunohistochemical staining.The relationship between Cx26 and NF-κB, and their correlations with clinical features were analyzed.
      ResultsThe positive expression rates of Cx26 and NF-κB in group A2 were higher than those in group A1(P < 0.01 and P < 0.05).The positive expression rates of Cx26 and NF-κB in group B were higher those in group A1(P < 0.01).The expression level of Cx26 was correlated with the menopause state and lymph node metastasis(P < 0.01), and the NF-κB level was correlated with pTNM staging and lymph node metastasis(P < 0.01 and P < 0.05).In lymph nodes metastatic lesions, the expression of Cx26 was positively correlated with the expression of NF-κB(P < 0.01).
      ConclusionsCx26 and NF-κB may co-participate in the invasion and metastasis of TNBC, and can be used as an effective indicator to predict TNBC metastasis and recurrence and evaluate clinical prognosis.
