越来越多的证据表明,非编码 RNA 在神经性疼痛 (NP) 中发挥着显着的作用;然而,NP 中竞争性内源 RNA 调节的机制仍不确定。本研究的目的是研究 NP 背后的分子过程。 我们利用基因表达综合 (GEO) 来获取 NP 相关的微阵列数据集,其中包括环状 RNA (circRNA) 和信使 RNA (mRNA) 的表达模式。随后进行了生物信息学分析和分子生物学实验。 研究结果表明,对目标基因进行富集研究对多种 NP 相关通路产生影响。值得注意的是,我们分离出了一个ceRNA子网络,其中包含两个上调的circRNA(Esrrg和Map3k3),它们主要通过调节整合素亚基β4(ITGB4)和两个下调的circRNA(Dgkb和Atp2a2)参与粘着斑途径,它们可能调节代谢相关分子脂肪酶A(LIPA)。 根据我们的研究结果,粘着斑和代谢信号通路在 NP 的进展中可能至关重要,一些 circRNA 可能通过 ceRNA 网络调节这一生物过程,这可能为潜在机制提供相关的见解。
Increasing evidence has shown that noncoding RNAs perform a remarkable function in neuropathic pain (NP); nonetheless, the mechanisms underlying the modulation of competitive endogenous RNA in NP remain uncertain. The goal of this research was to investigate the molecular processes underlying NP. We utilized the Gene Expression Omnibus (GEO) to obtain NP-related microarray datasets that included the expression patterns of circular RNAs (circRNAs) and messenger RNAs (mRNAs). Following that, bioinformatics analyses and a molecular biology experiment were carried out. According to the findings, carrying out enrichment studies of the targeted genes had an impact on a variety of NP-related pathways. Notably, we isolated a ceRNA subnetwork incorporating two upregulated circRNAs (Esrrg and Map3k3) which primarily participate in the focal adhesion pathway by regulating Integrin Subunit Beta 4 (ITGB4) and two downregulated circRNAs (Dgkb and Atp2a2), which potentially regulate metabolism-related molecule Lipase A (LIPA). According to our findings, the focal adhesion and metabolic signaling pathways could be critical in the advancement of NP, and some circRNA might regulate this biological process through the ceRNA network, which might offer pertinent insights into the underlying mechanisms.
