Pathway analysis tools

Definition

Pathway analysis tools are computational methods used to analyze biological pathways, which are series of interactions between molecules that lead to specific cellular functions. These tools help in interpreting large datasets, such as gene expression or proteomics data, by mapping them onto known biological pathways, enabling researchers to uncover insights into the underlying biological processes and regulatory mechanisms.
