We identified that transforming growth factor-β (TGF-β) induces long non-coding RNA (lncRNA) MIR100HG along with its host microRNAs (miRNAs) miR-100 and miR-125b, to regulate its response in pancreatic ductal adenocarcinoma (PDAC). Importantly let-7a, despite originating from MIR100HG, remains unchanged because post-transcriptionally repressed by lin-28 homolog B (LIN28B). A novel method for global miRNA-target discovery identified that miR-100/125b regulates crucial PDAC pathways.
我们发现,转化生长因子-β(TGF-β)可诱导长链非编码RNA(lncRNA)MIR100HG及其宿主微小RNA(miRNA)miR-100和miR-125b,以调节其在胰腺导管腺癌(PDAC)中的反应。重要的是,尽管let-7a源自MIR100HG,但由于其在转录后被lin-28同源物B(LIN28B)抑制,所以其表达保持不变。一种用于全局miRNA靶点发现的新方法确定,miR-100/125b可调节关键的PDAC通路。
