Trend research of vitamin D receptor: Bibliometric analysis

Studies on vitamin D receptor (VDR) and its association with multiple disorders are expanding. This bibliometric study aims to find and summarize VDR-related publications, and compare them across various countries, organizations, and journals to demonstrate trends in VDR research. VOSviewer and Excel 2019 were used to classify and summarize Web of Science articles from 1900 to mid-2021. Total records of 8762 articles were analyzed, and maps of co-citations bibliometric keywords co-occurrence were designed. In conclusion, relative research interest and published papers related to VDR were growing in the past 30 years. The United States of America dominates the research regarding VDR. The highest quality of VDR research was achieved by the University of California System, University of Wisconsin System, and Harvard University. J Steroid Biochem Mol Biol, PLoS One, and J Biol Chem are the leading three productive journals on VDR. Various aspects of vitamin D deficiency associated disorders and genetic studies regarding VDR, including single nucleotide polymorphism, gene variants, epigenome, long non-coding ribonucleic acid (lncRNA), and small nucleolar RNA host gene 6 are potentially the recent research hotspot in this field. Moreover, coronavirus disease, polycystic ovary syndrome, non-alcoholic fatty liver disease, gut microbiota, gestational diabetes, systemic sclerosis, and chemoresistance are the trending medical conditions associated with VDR.
