iPathwayGuide is a gene and protein expression analysis tool that uses a systems biology approach to identify significantly impacted pathways, gene ontology terms, diseases, and predicted microRNAs based on the given gene or protein differential expression signature. It uses an advanced pathway analysis approach that considers the role, positioning, and relationships of a given gene within a pathway, resulting in a significantly fewer false positives associated with pathway analysis.
