Sci Rep:EMT和MET miRNA调控在乳腺癌中的网络分析

2017-11-05 MedSci MedSci原创

在过去的几年中,微小RNA(miR)显示出对于乳腺肿瘤的发生和进展至关重要。为了解miRs对乳腺癌转录调控的影响,我们使用86例TCGA匹配的乳腺浸润癌和对照组织的RNA-Seq和miRNA-Seq测序数据构建了相互作用信息网络。结果显示,miRs是肿瘤和对照数据网络结构的决定因素。在肿瘤数据网络中,miR-200、miR-199和相邻的miRs似乎在上皮-间充质转变(EMT)和间充质-上皮转变(

在过去的几年中,微小RNA(miR)显示出对于乳腺肿瘤的发生和进展至关重要。为了解miRs对乳腺癌转录调控的影响,我们使用86例TCGA匹配的乳腺浸润癌和对照组织的RNA-Seq和miRNA-Seq测序数据构建了相互作用信息网络。

结果显示,miRs是肿瘤和对照数据网络结构的决定因素。在肿瘤数据网络中,miR-200、miR-199和相邻的miRs似乎在上皮-间充质转变(EMT)和间充质-上皮转变(MET)的生物学过程中调节获得上皮和间质性状。尽管肿瘤和对照网络之间存在结构差异,我们发现miR-200家族成员和VIM、ZEB-1/2和TWIST-1/2等基因之间存在保守的一套关联。

此外,在肿瘤网络中我们观察到大量miRs在DLK1-DIO3(Chr14q32)中定位到特定的染色体位置; 其中一些miRs也与EMT和MET调控有关。与EMT和TGF-β相关的通路增强了miR-200、miR-199和DLK1-DIO3簇在乳腺癌中的相关性。

通过这种方法,我们强调包含miR在基因调控网络构建中可以提高我们对乳腺癌生物学基础调控机制的理解。
