A bibliometric analysis of bladder cancer and microRNA research: Trends and advances from 2008 to 2022.

Bladder cancer (BC) is a significant global health issue with high incidence and mortality rates. MicroRNAs (miRNAs) play a crucial role in regulating gene expression and have been found to be dysregulated in BC. Understanding the role of miRNAs in BC development could lead to targeted therapies and improved patient management. Our study presents a thorough examination of the correlation between BC and miRNA research from 2008 to 2022. With the help of 3 powerful methods, including VOSviewer, Biblioshiny, and CiteSpace software, we analyzed the retrieved documents from "Core Collection databases online" on the Web of Science. In total, 798 articles were extracted from the Web of Science, and the number of published papers showed an upward trend from 2008 to 2019. The total number of citations was 21,233, of which the highest paper was a review article written by Chan Jiajia et al in 2018 with 752 citations. Based on the result of the coauthor analysis, Seki Naohiko was the most productive writer and China had the highest volume of published articles. Co-citation analysis was used to reveal the knowledge structure of the research field. In addition to the keywords "Bladder cancer" and "miRNA," "Proliferation," "Biomarkers," and "Apoptosis" were the high-frequency used keywords. Recently, increasingly researchers have paid more attention to the field about BC and miRNA around the worldwide. Through in-depth communication and close collaboration, the veil of miRNA in BC has gradually been unveiled. Bibliometric analysis helps to identify hotspots in research and areas for future investigation.
