Reactome Functional Interaction (FI) Network and ReactomeFIViz app
• No single mutated gene is necessary and sufficient to cause cancer.
• Typically one or two common mutations (e.g. TP53) plus rare mutations.
• Analyzing mutated genes in a network context:
• reveals relationships among these genes.
• can elucidate mechanism of action of drivers.
• facilitates hypothesis generation on roles of these genes in disease phenotype.
• Network analysis reduces hundreds of mutated genes to < dozen mutated pathways.

Inhibitor, Input2-Catalyst, Input2-Activator, Input2-Inhibtior,
Catalyst-Activator, Catalyst-Inhibitor, Activator-Inhibitor
Reaction Functional Interactions
• Convert reactions in pathways into pair-wise relationships
• Functional Interaction: an interaction in which two proteins are involved in the same reaction as input, catalyst, activator and/or inhibitor, or as components in a complex
Method and practical application: A human functional protein interaction network and its application to cancer data analysis, Wu et al. 2010 Genome Biology.

3) Pathway-Based Modeling
• Apply list of altered {genes, proteins, RNAs} to biological pathways.
• Preserve detailed biological relationships.
• Attempt to integrate multiple molecular alterations together to yield lists of altered pathway activities.
• Pathway modeling shades into Systems Biology
![Page 11: ReactomeFunctional Interaction Network and ReactomeFIVizapp · • Functional Interaction: an interaction in which two proteins are involved in the same reaction as input, catalyst,](https://reader033.vdocuments.site/reader033/viewer/2022050509/5f9a4fd1ebe2dd4498570ab9/html5/thumbnails/11.jpg)
Types of Pathway-Based Modeling
• Partial differential equations/boolean models, e.g. CellNetAnalyzer
• Mostly suited for biochemical systems (metabolomics)
• Network flow models, e.g. NetPhorest, NetworKIN
• Mostly suited for kinase cascades (phosphorylation info)
• Transcriptional regulatory network-based reconstruction methods, e.g. ARACNe (expression arrays)
• Probabilistic graph models (PGMs), e.g. PARADIGM
• Most general form of pathway modeling for cancer analysis at this time.
![Page 12: ReactomeFunctional Interaction Network and ReactomeFIVizapp · • Functional Interaction: an interaction in which two proteins are involved in the same reaction as input, catalyst,](https://reader033.vdocuments.site/reader033/viewer/2022050509/5f9a4fd1ebe2dd4498570ab9/html5/thumbnails/12.jpg)
Probabilistic Graphical Model (PGM) based Pathway Analysis
• Attempt to integrate multiple molecular alterations together to yield lists of altered pathway activities.
• Many omics data types available for one single patient
• CNV, gene expression, methylation, somatic mutations, etc.
• Pathway and network-based Simulation
• Find significantly impacted pathways for diseases
• Link pathway activities to patient phenotypes
• Predict drug effects: one drug or multiple drugs together?
