Epilepsy is a chronic neurological disorder characterized by recurring seizures. Although scalp electroencephalograms (EEG) and neuroimaging have been used in clinical diagnosis of epilepsy, the more economical, rapid and non-invasive biomarker is still desirable, contributing to the accurate clinical diagnosis and facilitating the appropriate treatment.
The expression of four epilepsy-associated miRNAs (miR-106b, miR-146a, miR-194-5p and miR-301a) was measured by quantitative RT-PCR in the serum of 90 epilepsy patients and control populations.
It was found that the serum miR-106b, miR-146a and miR-301a were significantly increased but serum miR-194-5p was significantly decreased in epilepsy patients compared with healthy control populations. In addition, serum miR-106b (r=0.6412) and miR-146a (r=0.5896) were correlated with NHS3 score in epilepsy patients. Furthermore, the ROC result of serum miR-106b for prediction of epilepsy was 0.786, higher than those of serum miR-146a (AUC=0.774), miR-194 (AUC=0.686) or miR-310a (AUC=0.696). The combination of serum miR-106b and miR-146a gained a better sensitivity/specificity for prediction of epilepsy (AUC=0.887).
Our preliminary findings indicate that upregulated serum miR-106b and miR-146a might be a potential biomarker for epilepsy evaluation.
癫痫是一种以反复发作性癫痫发作为特征的慢性神经系统疾病。尽管头皮脑电图(EEG)和神经影像学已用于癫痫的临床诊断,但仍需要更经济、快速且无创的生物标志物,以有助于准确的临床诊断并促进适当的治疗。
通过定量逆转录聚合酶链反应(RT-PCR)检测90例癫痫患者和对照人群血清中四种癫痫相关微小RNA(miR-106b、miR-146a、miR-194-5p和miR-301a)的表达。
发现与健康对照人群相比,癫痫患者血清miR-106b、miR-146a和miR-301a显著升高,而血清miR-194-5p显著降低。此外,癫痫患者血清miR-106b(r = 0.6412)和miR-146a(r = 0.5896)与NHS3评分相关。此外,血清miR-106b预测癫痫的ROC结果为0.786,高于血清miR-146a(AUC = 0.774)、miR-194(AUC = 0.686)或miR-310a(AUC = 0.696)。血清miR-106b和miR-146a联合使用对癫痫预测具有更好的敏感性/特异性(AUC = 0.887)。
我们的初步研究结果表明,血清miR-106b和miR-146a上调可能是评估癫痫的潜在生物标志物。
