Med Sci Monit:miR-148/152家族的表达水平与急性髓性白血病的临床表现及预后相关

2017-11-04 MedSci MedSci原创

微小RNAs(miRNAs)在急性髓性白血病(AML)的发展和进展中起重要作用。据报道miR-148/152家族在各种肿瘤中的表达不同。我们研究了miR-148/152家族在AML患者中的表达水平及其临床意义。通过qRT-PCR分析80名新诊断的AML患者和20名健康受试者中miR-148/152家族的表达水平。此外,我们还评估了miR-148/152家族的表达水平与AML患者的临床病理学特征之间

微小RNAs(miRNAs)在急性髓性白血病(AML)的发展和进展中起重要作用。据报道miR-148/152家族在各种肿瘤中的表达不同。我们研究了miR-148/152家族在AML患者中的表达水平及其临床意义。

通过qRT-PCR分析80名新诊断的AML患者和20名健康受试者中miR-148/152家族的表达水平。此外,我们还评估了miR-148/152家族的表达水平与AML患者的临床病理学特征之间的关系。

结果显示,与健康对照相比,AML患者中miR-148/152的表达水平明显较低(p <0.0001)。 miR148/152家族的表达与各种AML临床病理学风险参数(包括FAB分类、细胞遗传学和基因突变)有关。miR-148a/b高表达的患者数量在低危组明显增加,而在高危组则明显降低。 (分别为p = 0.025,p = 0.000)。miR-148b高表达的患者显示更高的完全缓解(CR)率(p = 0.043)。重要的是,miR-148a/b高表达与较低的复发率(分别为p = 0.035,p = 0.027)和较长的无复发生存期(RFS)(分别为p = 0.0321,p = 0.002)相关。亚组分析中,高风险组和中风险组患者的RFS明显受miR-148a/b表达的影响(分别为p = 0.0499,p = 0.0114)。

总之,该研究发现表明,AML患者miR-148/152家族的表达水平低于健康对照者,且与AML临床病理参数及疗效相关。miR-148/152家族可能是AML的一个新的生物标志物。
