三阴性乳腺癌患者癌组织中RUNX3及JAM-A表达变化及与疾病预后的相关性分析

Expression changes of RUNX3 and JAM-A in cancer tissues of patients with triplenegative breast cancer and their correlation with disease prognosis

目的探讨三阴性乳腺癌患者癌组织中Runt相关转录因子3(RUNX3)及连接黏附分子A(JAMA)表达变化及与疾病预后的相关性。方法选取2016年1月至2018年3月在新疆维吾尔自治区人民医院确诊的三阴性乳腺癌患者60例作为研究对象,收集患者乳腺癌组织及癌旁组织,通过实时荧光定量PCR及酶联免疫吸附试验检测并对比癌组织、癌旁组织中RUNX3、JAM-A转录水平及蛋白水平。对比不同临床病理特征三阴性乳腺癌患者癌组织中RUNX3及JAM-A转录水平及蛋白水平。采用Spearman相关性分析三阴性乳腺癌患者癌组织中RUNX3、JAM-A表达与患者不良预后的相关性。结果三阴性乳腺癌患者癌组织中RUNX3转录水平显著低于癌旁组织,JAM-A转录水平显著高于癌旁组织,差异有统计学意义(P<0.05)。三阴性乳腺癌患者癌组织中RUNX3蛋白水平显著低于癌旁组织,JAM-A蛋白水平显著高于癌旁组织,差异有统计学意义(P<0.05)。不同肿瘤最大径、TNM分期及淋巴结转移情况的三阴性乳腺癌患者癌组织中RUNX3及JAM-A转录水平比较,差异有统计学意义(P<0.05)。不同肿瘤最大径、TNM分期及淋巴结转移情况的三阴性乳腺癌患者癌组织中RUNX3及JAM-A蛋白水平比较,差异有统计学意义(P<0.05)。Spearman相关性分析表明,三阴性乳腺癌患者癌组织中RUNX3转录水平及蛋白水平与不良预后呈负相关,JAM-A转录水平及蛋白水平与不良预后呈正相关(P<0.05)。结论三阴性乳腺癌患者癌组织中RUNX3表达显著下调、JAM-A表达显著上调,且与患者预后均存在一定相关性,RUNX3及JAM-A可能是三阴性乳腺癌发生、发展过程中的重要调控因子。

Objective To explore the expression changes of Runt-related transcription factor 3(RUNX3)and junction adhesion molecule A(JAM-A)in cancer tissues of patients with triple-negative breast cancer and their correlation with disease prognosis.Methods Sixty patients with triple-negative breast cancer diagnosed in the People's Hospital of Xinjiang Uygur Autonomous Region from January 2016 to March 2018 were selected as the study objects.Breast cancer tissues and adjacent tissues of patients were collected.Real-time fluorescence quantitative PCR and enzyme-linked immunosorbent assay were used to detect and compare RUNX3 and JAM-A transcription levels and protein levels in cancer tissues and adjacent tissues.The transcription and protein levels of RUNX3 and JAM-A in cancer tissues of patients with triple-negative breast cancer with different clinicopathological characteristics were compared.The correlation between RUNX3 and JAM-A expression and poor prognosis in patients with triple-negative breast cancer was analyzed by Spearman correlation analysis.Results The transcription level of RUNX3 in cancer tissues was significantly lower than that in adjacent tissues,and the transcription level of JAM-A was significantly higher than that in adjacent tissues,with statistical significance(P<0.05).The level of RUNX3 protein in cancer tissues of patients with triple-negative breast cancer was significantly lower than that in adjacent tissues,and the level of JAM-A protein was signifi-cantly higher than that in adjacent tissues,with statistical significance(P<0.05).There were statistically significant differences in RUNX3 and JAM-A transcription levels in triple-negative breast cancer patients with different tumor maximum diameter,TNM stage and lymph node metastasis(P<0.05).There were statistically significant differences in RUNX3 and JAM-A protein levels among patients with triple-negative breast cancer with different tumor maximum diameter,TNM stage and lymph node metastasis(P<0.05).Spearman correlation analysis showed that RUNX3 transcription and protein levels were negatively correlated with poor prognosis,while JAM-A transcription and protein levels were positively correlated with poor prognosis in patients with triple-negative breast cancer(P<0.05).Conclusion RUNX3 expression is significantly downregulated and JAM-A expression is significantly up-regulated in cancer tissues of patients with triple-negative breast cancer,and there is a certain correlation with patient prognosis.RUNX3 and JAM-A may be important regulatory factors in the occurrence and development of triple-negative breast cancer.
