Qiao P, Wu W, Wu Y, Wang X. miR-328a-3p modulates the proliferative and migratory abilities of Schwann cells in peripheral nerves. Neurosci Lett 2022; 791:136893. [PMID: 36191794 DOI: 10.1016/j.neulet.2022.136893] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 09/21/2022] [Accepted: 09/27/2022] [Indexed: 11/19/2022]
Abstract
MicroRNAs (miRNAs) modulate Schwann cell phenotype. Here miR-328a-3p amounts after peripheral nerve damage were determined in injury stumps of the sciatic nerve in rats administered surgical crush. Quantitative real-time reverse transcription-polymerase chain reaction was performed to assess miR-328a-3p levels 0, 1, 4, 7 and 14 days post-sciatic nerve damage. The results showed miR-328a-3p was upregulated after nerve damage. CCK8 and EdU assays revealed elevated miR-328a-3p amounts suppressed Schwann cell viability and proliferation, respectively. Next, the migratory potential of cells was assessed by the Transwell chamber and wound healing assays. We found elevated miR-328a-3p amounts also suppressed Schwann cell migration. Conversely, low miR-328a-3p amounts promoted Schwann cell migration. The possible miR-328a-3p targets were predicted by bioinformatics. The 15 target genes retrieved provided insights into miR-328a-3p's effects on Schwann cells and expanded the understanding of miR-328a-3p's biological functions in the peripheral nervous system. Collectively, these findings revealed miR-328a-3p's effects on Schwann cells and provided further insights into the functions of miRNAs in peripheral nerves.

Front Neurol 2022; 13:872261. [PMID: 35669875 PMCID: PMC9163812 DOI: 10.3389/fneur.2022.872261] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Accepted: 04/19/2022] [Indexed: 12/17/2022] Open
Abstract
BackgroundPeripheral nerve injury (PNI) is very common in clinical practice, which often reduces the quality of life of patients and imposes a serious medical burden on society. However, to date, there have been no bibliometric analyses of the PNI field from 2017 to 2021. This study aimed to provide a comprehensive overview of the current state of research and frontier trends in the field of PNI research from a bibliometric perspective.MethodsArticles and reviews on PNI from 2017 to 2021 were extracted from the Web of Science database. An online bibliometric platform, CiteSpace, and VOSviewer software were used to generate viewable views and perform co-occurrence analysis, co-citation analysis, and burst analysis. The quantitative indicators such as the number of publications, citation frequency, h-index, and impact factor of journals were analyzed by using the functions of “Create Citation Report” and “Journal Citation Reports” in Web of Science Database and Excel software.ResultsA total of 4,993 papers was identified. The number of annual publications in the field remained high, with an average of more than 998 publications per year. The number of citations increased year by year, with a high number of 22,272 citations in 2021. The United States and China had significant influence in the field. Johns Hopkins University, USA had a leading position in this field. JESSEN KR and JOURNAL OF NEUROSCIENCE were the most influential authors and journals in the field, respectively. Meanwhile, we found that hot topics in the field of PNI focused on dorsal root ganglion (DRG) and satellite glial cells (SGCs) for neuropathic pain relief and on combining tissue engineering techniques and controlling the repair Schwann cell phenotype to promote nerve regeneration, which are not only the focus of research now but is also forecast to be of continued focus in the future.ConclusionThis is the first study to conduct a comprehensive bibliometric analysis of publications related to PNI from 2017 to 2021, whose bibliometric results can provide a reliable source for researchers to quickly understand key information in this field and identify potential research frontiers and hot directions.
