Abstract

Background and objectives: Parkinson's disease (PD) is a common neurodegenerative disorder with unclear molecular mechanisms. Noncoding RNAs, such as microRNAs (miRNAs) and long noncoding RNAs (lncRNAs), have been identified as critical regulators of gene expression. This study aimed to investigate the triple network of lncRNA-miRNA-mRNA, known as competing endogenous RNAs (ceRNAs), and to identify essential lncRNAs that regulate PD-related gene expression through their target miRNAs. The study also identified a common triple network between COVID-19 and PD that may contribute to exacerbating PD symptoms. Methods: A bioinformatics approach was employed to construct a PD ceRNA network using common PD genes, miRNAs and lncRNAs with the highest interaction with their targets. Also, a PD-COVID-19 triple network was constructed by integrating PD network nodes into the COVID-19 network. Results: The PD ceRNA network comprised 34 nodes, including 12 lncRNAs, 16 miRNAs with interconnections and six mRNAs, some of which were related to COVID-19. The network showed parallel expression of the SNCA and PARK7 genes as well as the NEAT1 and MALAT1 lncRNAs in both PD and COVID-19. Conclusions: This study provide insights into the molecular mechanisms underlying the worsening of symptoms in PD patients with COVID-19. The PD and COVID-19 ceRNA network indicates that coronavirus could worsen PD symptoms by altering the expression of some genes related to PD. Therefore, COVID-19 could dysregulate the common RNAs involved in PD through lncRNAs, miRNAs. © 2024 The Author(s).
