Abstract
Calcium channels are involved in pathologies across all the major therapeutic areas involving the cardiac, neurological, metabolic, and respiratory systems. Although calcium channels have been the hotspot of multidisciplinary research for decades, the hotspots and frontier trends of calcium channel research have not been comprehensively analyzed by bibliometrics. Here, we collected scientific publications on calcium channel research in the past decade to explore the hotspots and frontier directions of calcium channel research by bibliometric analysis. Publications were retrieved from the Web of Science Core Collection (WOSCC) database from 2010 to 2019. Citespace5.6 R5 was used to perform bibliometric analysis on the countries, institutions, authors, and related research areas. In total, 26,664 articles were analyzed. The United States and the University of California are the most productive country and institution for calcium channel research. The most productive researchers were Lang, Florian, Zamponi, Gerald W, and Jan, Chung-Ren. PLoS One had the most significant number of publications (986). Research hotspots can be summarized as the regulation mechanism of calcium channels, calcium channel blockers, and ryanodine receptor. The research frontiers were the effect of calcium channel on cell proliferation, gene mutation, calcium channels in neuropathic pain, and calcium-signaling pathway. This is the first report to visualize and analyze hotspots and emerging trends in calcium channel research.
