Pathway databases contain biological pathways for metabolic, signaling, and regulatory pathway analysis. Several databases containing information on cell signaling pathways have been developed in conjunction with data access and analysis methodologies (Bauer?Mehren, Furlong et al. 2009). Many databases have been published in this Research Area, such as KEGG pathway (Kanehisa, Furumichi et al. 2017), BiGG Models DB (Rigden, Fernandez-Suarez et al. 2016), MiST 3.0 DB (Gumerov, Ortega et al. 2020) and Pathway Commons db (Blinov, Schaff et al. 2014) in this study, we have collected almost all of the updated 66 Pathway databases and can be easily accessed by clicking on the required database.
