Clinica Chimica Acta:循环miR-214-3p可预测鼻咽癌的复发或转移?

2020-04-13 MedSci原创 MedSci原创

由于在血液中的稳定形式,循环中的microRNAs (miRNAs)被认为是许多癌症中有具有前景的新型微创生物标志物。然而,目前关于鼻咽癌中miRNA的研究相对较少。

由于在血液中的稳定形式,循环中的microRNAs (miRNAs)被认为是许多癌症中有具有前景的新型微创生物标志物。然而,目前关于鼻咽癌中miRNA的研究相对较少。

根据GEO数据库和以前发表的报告,我们选择了21个失调的mirna通过微阵列分析进行筛选(20个NPC样本vs 10个对照组)。然后通过定量逆转录聚合酶链反应(qRT-PCR)在训练和验证集检测并验证失调的MIRNA。然后在评估集中评估候选miR-214-3p,包括miR-214-3p与临床病理特征、鼻咽癌患者动态变化以及鼻咽癌复发或转移的预测价值之间的关系。

通过微阵列分析,与健康对照组相比,7个miRNA发生了显著变化。MiR-214-3p在qRT-PCR的训练和验证组中表达最显著。血浆miR-214-3p表达与UICC分期及鼻咽癌复发或转移显著相关。鼻咽癌患者治疗后随访血浆miR-214-3p表达逐渐下降。复发或转移的患者往往在同一时间点血浆miR-214-3p水平升高。通过Kaplan-Meier生存曲线分析(P = 0.006),预处理前miR-214-3p的高表达(≥3.12)与NPC复发或转移显著相关。

研究表明,循环miR-214-3p可作为预测鼻咽癌患者复发或转移的非侵袭性生物标志物。
