The Gene Ontology (GO) provides a system for hierarchically classifying genes or gene products into terms organized in a graph structure (or an ontology).The terms are groups into three categories: molecular function (describing the molecular activity of a gene), biological process (describing the larger cellular or physiological role carried out by the gene, coordinated with other genes), and ...
Reactome is a free online database of biological pathways. [ 1 ] [ 2 ] [ 3 ] It is manually curated and authored by PhD-level biologists, in collaboration with Reactome editorial staff. The content is cross-referenced to many bioinformatics databases.
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 ...
Metascape is a free gene annotation and analysis resource that helps biologists make sense of one or multiple gene lists. Metascape provides automated meta-analysis tools to understand either common or unique pathways and protein networks within a group of orthogonal target-discovery studies.
The Gene Ontology (GO) is a major bioinformatics initiative to unify the representation of gene and gene product attributes across all species. [1] More specifically, the project aims to: 1) maintain and develop its controlled vocabulary of gene and gene product attributes; 2) annotate genes and gene products, and assimilate and disseminate annotation data; and 3) provide tools for easy access ...
PathVisio is a free open-source pathway analysis and drawing software. It allows drawing, editing, and analyzing biological pathways.Visualization of ones experimental data on the pathways for finding relevant pathways that are over-represented in your data set is possible.
Over-representation analysis [ edit ] Using the web-interface of the database, one can perform overrepresentation analysis, based on biochemical pathways or on neighbourhood-based entity sets (NESTs) that constitute sub-networks of the overall interaction network containing all physical entities around a central one within a "radius" (number of ...
As noted above MetPA performs two types of pathway analysis: 1) Pathway (or Metabolite Set) Enrichment Analysis; and 2) Pathway Topological Analysis. Pathway Enrichment Analysis (which is similar to MSEA) identifies which metabolic pathways have compounds (from the input lists) that are over-represented and have significant perturbations to ...
