基于Web of Science和CNKI数据库的DNA甲基化文献可视化分析OA北大核心CSTPCD

Currently,DNA methylation has become one of the research foci in the field of life sciences and medicine,with a rapid increase in related literature.In order to understand the overall development and trends of international research related to DNA methylation,this study used bibliometrics to analyze the DNA methylation-related publications in the Web of Science(WOS)and the China's CNKI database o-ver the past thirty years,and applied VOSviewer software for visualization.The retrieval and analysis re-vealed a total of 21,262 DNA methylation-related papers in the WOS database and 25,664 papers in the CNKI database.In WOS database,the United States has an absolute advantage in the number of relevant papers,with relatively high average citation frequencies and h-indexes.Research directions mainly focus on genetics,biochemistry and molecular biology,and oncology.Keywords primarily include"epigenetics","gene expression"and"cancer".Among them,gene expression is the focus and direction of DNA methylation research.These keywords reflect the wide application and deep exploration of DNA methylation in these fields.In the CNKI database,the main publications are in journals such as Cancer,China Animal Husbandry & Veterinary Medicine,and Journal of Animal Husbandry and Veterinary Medicine.Through the analysis of DNA meth-ylation related literature in WOS and CNKI databases,this study provides valuable information and refer-ence for subsequent research in the field of DNA methylation.
