In bioinformatics research, pathway analysis software is used to identify related proteins within a pathway or building pathway de novo from the proteins of interest. This is helpful when studying differential expression of a gene in a disease or analyzing any omics dataset with a large number of proteins. By examining the changes in gene expression in a pathway, its biological causes can be explored. Pathway is the term from molecular biology which depicts an artificial simplified model of a process within a cell or tissue. A typical pathway model starts with an extracellular signaling molecule that activates a specific receptor, thus triggering a chain of protein-protein or protein-small molecule interactions. Pathway analysis helps to understand or interpret omics data from the point of view of canonical prior knowledge structured in the form of pathways diagrams. It allows finding distinct cell processes (Cellular processes), diseases or signaling pathways that are statistically associated with selection of differentially expressed genes between two samples. Often but erroneously pathway analysis is used as synonym for network analysis (functional enrichment analysis and gene set analysis).
