The microRNA, miR-139-5p, plays an important role in the initiation and progression of various tumor types including osteosarcoma (OS).
This study aimed to detect the serum miR-139-5p expression in OS and analyze its association with clinical variables.
Blood samples were taken from 98 OS patients and 50 healthy individuals, and serum miR-139-5p levels were measured by quantitative reverse transcription-polymerase chain reaction.
We found the expression of serum miR-139-5p in OS patients was significantly lower than that in healthy individuals, and miR-139-5p levels were dramatically decreased in patients with distant metastasis or in higher clinical stage. Receiver-operating characteristic (ROC) analysis revealed that serum miR-139-5p could well discriminate OS patients from healthy controls with a high sensitivity and specificity. Moreover, low serum miR-139-5p expression was strongly associated with distant metastasis, tumor stage and shorter overall survival. Both univariate and multivariate analyses showed that serum miR-139-5p level could serve as an independent prognostic marker for OS.
Taken together, data from this study demonstrates that serum miR-139-5p could be used as a tumor biomarker for OS diagnosis and prognosis.
微小 RNA(miR-139-5p)在多种肿瘤类型的发生和发展中起着重要作用,包括骨肉瘤(OS)。
本研究旨在检测 OS 患者血清 miR-139-5p 的表达,并分析其与临床变量的关系。
采集 98 例 OS 患者和 50 例健康个体的血样,通过定量逆转录-聚合酶链反应(qRT-PCR)检测血清 miR-139-5p 水平。
我们发现 OS 患者血清 miR-139-5p 的表达明显低于健康个体,且远处转移或临床分期较高的患者 miR-139-5p 水平显著降低。受试者工作特征(ROC)分析表明,血清 miR-139-5p 能够很好地区分 OS 患者与健康对照者,具有较高的灵敏度和特异性。此外,低血清 miR-139-5p 表达与远处转移、肿瘤分期和总生存期较短密切相关。单因素和多因素分析均表明,血清 miR-139-5p 水平可作为 OS 的独立预后标志物。
综上所述,本研究数据表明,血清 miR-139-5p 可作为 OS 诊断和预后的肿瘤标志物。
