NCI-Nature Pathway Interaction Database; Netpath: curated resource of signal transduction pathways in humans; Reactome: navigable map of human biological pathways, ranging from metabolic processes to hormonal signalling (Ontario Institute for Cancer Research, European Bioinformatics Institute, NYU Langone Medical Center, Cold Spring Harbor ...
All pathways have an open license and can be freely used. Reactome is a free and manually curated online database of biological pathways. NCI-Nature Pathway Interaction Database is a free biomedical database of human cellular signaling pathways (new official name: NCI Nature Pathway Interaction Database: Pathway, synonym: PID).
KEGG (Kyoto Encyclopedia of Genes and Genomes) is a collection of databases dealing with genomes, biological pathways, diseases, drugs, and chemical substances.KEGG is utilized for bioinformatics research and education, including data analysis in genomics, metagenomics, metabolomics and other omics studies, modeling and simulation in systems biology, and translational research in drug development.
Pathway resources and types of pathway analysis using databases like KEGG, Reactome and WikiPathways. [1]Pathway is the term from molecular biology for a curated schematic representation of a well characterized segment of the molecular physiological machinery, such as a metabolic pathway describing an enzymatic process within a cell or tissue or a signaling pathway model representing a ...
Examples of biological pathways in Reactome include signal transduction, innate and acquired immune function, transcriptional regulation, programmed cell death and classical intermediary metabolism. The pathways represented in Reactome are species-specific, with each pathway step supported by literature citations that contain an experimental ...
WikiPathways is originally built using MediaWiki software, [4] a custom graphical pathway editing tool (PathVisio [5]) and integrated BridgeDb [6] databases covering major gene, protein, and metabolite systems. WikiPathways was founded in 2008 by Thomas Kelder, Alex Pico, Martijn Van Iersel, Kristina Hanspers, Bruce Conklin and Chris Evelo.
Based on the manual curation done, BioCyc database family is divided into 3 tiers: Tier 1: Databases which have received at least one year of literature based manual curation. Currently there are seven databases in Tier 1. Out of the seven, MetaCyc is a major database that contains almost 2500 metabolic pathways from many organisms.
Chado makes extensive use of controlled vocabularies to type all entities in the database; for example: genes, transcripts, exons, transposable elements, etc., are stored in a feature table, with the type provided by Sequence Ontology. When a new type is added to the Sequence Ontology, the feature table requires no modification, only an update ...
