Bibliometric Analysis and Science Mapping on RNA-seq and Gene Expression in Sheep

Abstract

This study aimed to determine the development of research articles on ‘RNA-sequencing and gene expres-sion’ in sheep between 2011-2023 in the Web of Science (WoS) database by scientific mapping method. In this regard, 205 articles were examined in the first search using the relevant keywords, and 124 articles suitable for analysis. They were analysed with the Shiny web application of the Bibliometrix R package, and VOSviewer. The results determined that the country with the most publications in the relevant field was China, the related institution with the most studies was “The University of Edinburgh”, and the journal with the most publications was “PLoS One”. According to the key-word analysis, the trend topics started from studies on granulosa cells and showed into research areas such as im-mune response, growth, pathway and meat quality. In the abstract analysis, the word ‘transcriptome’ and words such as mammary gland, muscle, fertility, Peripheral Blood Mononuclear Cells (PBMCs), lactation, fat storage were found together, while the words forming the parasitic agents, drug resistance, miRNA studies were clustered in different groups. The scarcity of the articles obtained in the analysed period reveals the openness of the study area. It can be suggested that the researchers who will plan to work on this subject can plan studies on the identification of variants belonging to different sheep breeds, resistance to antiparasitic drugs used in sheep, meat yield, disease resistance, reproductive tissues and organs, as well as designing all these studies as study subjects based on climate change and global warming factor.
