Abstract

Long non-coding RNA (lncRNA) distal-less homeobox 6 antisense RNA 1 (DLX6-AS1) is elevated in a variety of cancers, including non-small cell lung cancer (NSCLC) and cervical cancer. Although it was found that the microRNA-16-5p (miR-16), which is known to regulate autophagy and apoptosis, had been downregulated in similar cancers. Recent research has shown that in tumors with similar characteristics, DLX6-AS1 acts as a sponge for miR-16 expression. However, the cell death-related molecular mechanism of the DLX6-AS1/miR-16 axis has yet to be investigated. Therefore, we propose a dynamic Boolean model to investigate gene regulation in cell death processes via the DLX6-AS1/miR-16 axis. We found the finest concordance when we compared our model to many experimental investigations including gain-of-function genes in NSCLC and cervical cancer. A unique positive circuit involving BMI1/ATM/miR-16 is also something we predict. Our results suggest that this circuit is essential for regulating autophagy and apoptosis under stress signals. Thus, our Boolean network enables an evident cell-death process coupled with NSCLC and cervical cancer. Therefore, our results suggest that DLX6-AS1 targeting may boost miR-16 activity and thereby restrict tumor growth in these cancers by triggering autophagy and apoptosis.

摘要

长链非编码RNA(lncRNA)远端同源盒6反义RNA 1(DLX6-AS1)在包括非小细胞肺癌(NSCLC)和宫颈癌在内的多种癌症中表达上调。尽管已知调节自噬和凋亡的微小RNA-16-5p(miR-16)在类似癌症中表达下调。最近的研究表明,在具有相似特征的肿瘤中,DLX6-AS1充当miR-16表达的海绵。然而,DLX6-AS1/miR-16轴与细胞死亡相关的分子机制尚未得到研究。因此,我们提出了一个动态布尔模型,以研究通过DLX6-AS1/miR-16轴在细胞死亡过程中的基因调控。当我们将模型与包括NSCLC和宫颈癌中功能获得性基因在内的许多实验研究进行比较时,发现了最佳的一致性。我们还预测了一个涉及BMI1/ATM/miR-16的独特正反馈回路。我们的结果表明,该回路在应激信号下对调节自噬和凋亡至关重要。因此,我们的布尔网络能够清晰地呈现与NSCLC和宫颈癌相关的细胞死亡过程。因此,我们的结果表明,靶向DLX6-AS1可能会增强miR-16的活性,从而通过触发自噬和凋亡来限制这些癌症中的肿瘤生长。
