血浆中肿瘤抑制因子miR-107的减少与肿瘤进展有关,是治疗胰腺癌新型靶点。本研究探讨胰腺癌(PCa)患者肿瘤抑制微小RNA(miRNA)血浆水平的降低,以阐明其作为新生物标志物和治疗靶点的潜力。

研究使用基于microRNA阵列的方法通过比较PCa患者和健康志愿者的血浆水平来选择候选者。选择六个下调的miRNA(miR-107,miR-126,miR-451,miR-145,miR-491-5p和miR-146b-5p)。使用100例PCa患者和80例健康志愿者的样本进行小规模和大规模分析显示,与健康志愿者相比,miR-107是PCa患者中最多的下调miRNA(P  <0.0001;接受者操作特征曲线下面积,0.851)。低miR-107血浆水平与晚期T期,N期,和肝转移有关,是预测PCa患者预后不良的独立因素(P= 0.0424;风险比2.95)。

总之,该研究表明,miR-107在PCa细胞中的过表达通过产生p21诱导G1/S阻滞,并通过Notch2的转录调控抑制细胞增殖。在体内,miR-107血浆水平的恢复和维持显着抑制小鼠的肿瘤进展。血浆中肿瘤抑制因子miR-107的消耗与肿瘤进展和不良结局有关。血浆miR-107水平的恢复可能是PCa的新型抗癌治疗策略。
