PathFXweb

PathFXweb analyzes protein-protein interaction networks and performs phenotype enrichment using the PathFX algorithm to identify drug-associated safety and efficacy signals.

Key Features:

• Protein-Protein Interaction Network Analysis: Constructs and analyzes protein-protein interaction networks surrounding drug target(s) to map network-level drug effects.
• Phenotype Enrichment Analysis: Identifies phenotypes that are statistically enriched within the target-centered network compared to the background network.
• Integration of Heterogeneous Datasets: Aggregates and integrates multiple datasets to inform construction of interaction networks and phenotype associations.
• Visualization and Phenotype Clustering: Provides visualization and phenotype clustering to support interpretation of network and enrichment results.

Scientific Applications:

• Safety Liability Identification: Detects potential adverse phenotype associations linked to drug targets to inform safety assessment.
• Efficacy and Mechanism-of-Action Inference: Reveals phenotype and pathway associations that support hypotheses about drug efficacy and mechanism of action.
• Early-Stage Drug Development Analysis: Supports evaluation of target-associated pathway effects and phenotype signals during early development.

Methodology:

Integrates multiple datasets to construct protein-protein interaction networks around drug targets, analyzes these networks to identify statistically enriched phenotypic associations using the PathFX algorithm, and applies visualization and phenotype clustering for interpretation.
