It has been found that each non-coding RNA (ncRNA) can act not only through its target gene, but also interact with each other to act on biological traits, and this interaction is more common. Many studies focus mainly on the analysis of microRNA(miRNA) and message RNA (mRNA) interactions. In this study, we investigated miRNA and long non-coding RNA (lncRNA) interactions using support vector regression (SVR) for prediction of new target genes in Arabidopsis thaliana and identify some regulatory roles in stress response. The networks of miRNA-mRNA, miRNA-lncRNA and miRNA-mRNA-lncRNA were constructed. They were further analyzed and interpreted in R. We showed that miRNA with low sequence number, targeted lncRNA with high sequence number and miRNA with high sequence number targeted lncRNA with low sequence number. The experimental results showed that there is a regulatory relationship between miRNA-lncRNA. New RNA targets were predicted using SVR with new gene expression mechanism and the stress related functions were annotated.
现已发现,每种非编码 RNA(ncRNA)不仅可以通过其靶基因发挥作用,还可以相互作用以影响生物特征,而且这种相互作用更为常见。许多研究主要集中在 microRNA(miRNA)和 message RNA (mRNA)相互作用的分析上。在这项研究中,我们使用支持向量回归(SVR)研究了 miRNA 和长非编码 RNA(lncRNA)的相互作用,以预测拟南芥中的新靶基因,并确定一些在应激反应中的调节作用。构建了 miRNA-mRNA、miRNA-lncRNA 和 miRNA-mRNA-lncRNA 的网络。在 R 中进一步分析和解释了这些网络。我们发现 miRNA 具有低序列数,靶向 lncRNA 具有高序列数,而 miRNA 具有高序列数靶向 lncRNA 具有低序列数。实验结果表明 miRNA-lncRNA 之间存在调节关系。使用 SVR 预测新的 RNA 靶标,并注释与新基因表达机制和应激相关的功能。
