Non-coding RNAs (ncRNAs) can control the flux of genetic information; affect RNA stability and play crucial roles in mediating epigenetic modifications. A number of studies have highlighted the potential roles of both virus-encoded and host-encoded ncRNAs in viral infections, transmission and therapeutics. However, the role of an emerging type of non-coding transcript, circular RNA (circRNA) in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has not been fully elucidated so far. Moreover, the potential pathogenic role of circRNA-miRNA-mRNA regulatory axis has not been fully explored as yet. The current study aimed to holistically map the regulatory networks driven by SARS-CoV-2 related circRNAs, miRNAs and mRNAs to uncover plausible interactions and interplay amongst them in order to explore possible therapeutic options in SARS-CoV-2 infection. Patient datasets were analyzed systematically in a unified approach to explore circRNA, miRNA, and mRNA expression profiles. CircRNA-miRNA-mRNA network was constructed based on cytokine storm related circRNAs forming a total of 165 circRNA-miRNA-mRNA pairs. This study implies the potential regulatory role of the obtained circRNA-miRNA-mRNA network and proposes that two differentially expressed circRNAs hsa_circ_0080942 and hsa_circ_0080135 might serve as a potential theranostic agents for SARS-CoV-2 infection. Collectively, the results shed light on the functional role of circRNAs as ceRNAs to sponge miRNA and regulate mRNA expression during SARS-CoV-2 infection.
非编码 RNA(ncRNAs)可以控制遗传信息的流动;影响 RNA 的稳定性,并在介导表观遗传修饰中发挥关键作用。许多研究强调了病毒编码和宿主编码 ncRNAs 在病毒感染、传播和治疗中的潜在作用。然而,环状 RNA(circRNA)作为一种新兴的非编码转录本,在严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)感染中的作用尚未得到充分阐明。此外,circRNA-miRNA-mRNA 调控轴的潜在致病作用尚未得到充分探索。本研究旨在全面绘制由 SARS-CoV-2 相关 circRNAs、miRNAs 和 mRNAs 驱动的调控网络,以揭示它们之间可能的相互作用和相互作用,从而探索 SARS-CoV-2 感染的可能治疗选择。通过系统的统一方法分析患者数据集,以探索 circRNA、miRNA 和 mRNA 的表达谱。基于细胞因子风暴相关 circRNAs 构建了 circRNA-miRNA-mRNA 网络,共形成 165 个 circRNA-miRNA-mRNA 对。本研究表明获得的 circRNA-miRNA-mRNA 网络具有潜在的调控作用,并提出两个差异表达的 circRNA hsa_circ_0080942 和 hsa_circ_0080135 可能作为 SARS-CoV-2 感染的潜在治疗剂。总之,这些结果揭示了 circRNAs 作为 ceRNA 在外泌体中吸附 miRNA 并调节 SARS-CoV-2 感染过程中 mRNA 表达的功能作用。
