Gene Editing and Aging: A Bibliometric Analysis of Global Trends and Frontier Themes (2015-2024)

Abstract

Objective The accumulation of DNA damage and mutations is a key contributor to aging. Recent studies have shown that disrupting the Beclin 1-BCL2 autophagy regulatory complex through gene editing can extend lifespan in mice. The precise application of gene editing technologies offers a promising strategy for aging. This study conducted a bibliometric analysis to map the knowledge landscape of gene editing and aging. Methods We retrieved publications related to genome editing and aging from the Web of Science Core Collection, covering the period from 2015 to 2024. The data were analyzed using VOSviewer and R package Bibliometrix. These tools enabled us to identify the most productive researchers, journals, institutions, countries and visualized current trends, emerging research hotspots. Results A total of 982 publications on genome editing and aging were identified. The United States (n=285) and China (n=214) form a dual-core structure leading global output. Harvard University (n=116) emerged as the most prolific institution. Scientific Reports was the top-publishing journal, with 23 articles in 2024. ZHANG Y (n=12, citations=102, H-index=6) was identified as the most productive author. KIM Es 2017 publication in Nature Communications (TC=494, TC/year=54.9, NTC=9.33) has had a significant and ongoing impact. The analysis indicates that future directions will include CRISPR optimization and AI-assisted genomic analysis. Conclusion This study presents the first comprehensive bibliometric analysis and visualization of the knowledge structure in gene editing and aging research up to 2024. It offers researchers a detailed overview of current developments, trends, and emerging frontiers in this rapidly evolving domain.
