Genome Editing Meta-database (GEM) is a genome editing metadatabase developed to comprehensively collect metadata related to past genome editing experiments (an original paper). The GEM is systematically extracted via specialized text-mining from PubMed and PubMed Central (PMC) literatures that contain experiments involving the use of the seven types of genome editing tools. A dataset consisting of 50,162 entries of metadata based on 15,952 studies with 1,088 species was constructed and can be searched and retrieved graphically in the GEM web interface.
