  15. The Ingenuity OntologyStructures, translates, and integrates information • Helps you to find highly relevant and contextual information. ex: direction of change • Makes information computationally accessible and available for queries. ex: • Query over any type of connections (molecular, cellular, organism) • Make leaps from one concept to another and ask “Is there a path that might lead from A to B? • Ensures we are all talking about the same concept– regardless of your preferred nomenclature (semantically consistent). : THE INGENUITY ONTOLOGY ex : IL-1 beta increases regulation of COX1: Which COX1? cyclooxygenase or cytochrome c oxidase – both are enzymes

  16. Extensive: Leverages knowledge in one place Largest scientific knowledge base of its kind with modeled relationships between proteins, genes, complexes, cells, tissues, drugs, pathways and diseases Structured:Captures relevant details Scientific statements are modeled into Findings (often causal) using the Ingenuity Ontology Expert Review Process: Checked for accuracy Findings go through extensive QC process Timely: Frequent updates and up-to-date knowledge Findings are added weekly Explore the Ingenuity Knowledge Base Ingenuity Expert Findings THE INGENUITY KNOWLEDGE BASE • From the full text • Contextual details • Timely • High-quality Ingenuity ExpertAssist Findings • High coverage (abstracts) • Timely • High-quality Ingenuity Expert Knowledge Ingenuity Supported Third Party Information

  19. Questions Arise During ExperimentalProcess : • How Can IPA Help You?

  20. IPA Allows Scientists to Explore Biological Findings • Browse and Search the comprehensive Ingenuity Knowledge Base • Gene/Chemical Search • Functions Search • Pathway Search • Build Pathways; Build Hypotheses • Use Build Tools to explore which molecules have molecular interactions with molecule(s) of interest • Use the Overlay tools to layer additional functional, drug and biomarker information • Analyze Data; Interpret Cause and Effect; Discover the Biology • Gain insights into the Biological Functions, Canonical Pathways and Molecular Networks that involve dataset molecules • Predict Transcription Factors & Upstream Regulators involved in transcriptional changes and connect Regulators into Mechanistic and Causal Networks • Explore the Causal Effects of network changes • Filter Datasets • Biomarkers and Biofluid expression • microRNA Target Filter for miRNA-mRNA relationships

  21. Search for Genes, Chemicals, Diseases, Functions, or Pathways

  22. Build Pathways; Build HypothesesSearch and Explore Examples • Tell me about my gene of interest – Insulin / INS • What canonical signalling pathways does it appear in? • What are the transcriptional regulators of this gene? • What Ligand-Dependent Nuclear Receptors are regulated by these Transcription Factors? • What GPCRs are involved in diabetes? • How do they interconnect? • What other biological processes (functions) are these genes involved in? • What are the molecular connections that link these genes to cytokines involved in obesity? • What drugs target these genes? • Tell me about rosiglitazone? • What clinical trials are running with rosiglitazone? • How does rosiglitazone treatment affect the gene expression of these diabetes GPCRs and obesity cytokines? • What are the upstream regulators of the gene expression changes induced by rosiglitazone treatment?

  24. View Canonical Pathways and Link Additional Molecules

  25. Cause and Effect Analytics • Upstream Regulator Analysis (including Transcription Factors) • Predicts which Transcriptional Regulators and other upstream molecules are driving gene expression changes and predicts which are activated / inhibited to explain gene expression observed in a dataset • Create Mechanistic and Causal Networks • Connect upstream regulators into networks to help understand the regulatory control of the gene expression seen • Use the Ingenuity Knowledge Base of causal relationships to predict regulators that can be causally linked to the dataset molecules for unprecedented understanding of biological regulation • Downstream Effects Analysis • Predict increase or decreases in downstream biological processes (functions) and disease using the direction of change in your gene expression data • Molecule Activity Predictor • Visualize the predicted activity of causally connected molecules in Networks and Pathways

  26. Upstream Regulators and Mechanistic Networks Upstream Regulator Regulator Dataset Molecules Mechanistic Network Algorithm chains interacting regulators together to create a “Mechanistic Network” Upstream Regulator Additional Upstream Regulators Dataset Molecules

  27. Proprietary and Confidential Upstream Regulator AnalysisIdentify important signaling molecules for a more complete regulatory picture • Quickly filter by molecule type • Filter by biological context • Generate regulators-targets network to identify key relationships

  28. Mechanistic NetworksHow might the upstream molecule drive the observed expression changes? • Hypothesis generation and visualization • Each hypothesis generated indicates the molecules predicted to be in the signaling cascade

  29. Interpret Downstream Biological Functions Identify over-represented biological functions and predict how those functions are increased or decreased in the experiment

  30. Compare Canonical Pathways across analyses as a heatmap

  31. BioProfiler*: Find, Filter and Explore • Find molecules causally relevant to a disease, phenotype, or function • Filter by specific genetic evidence or species • Explore association with other similar diseases or phenotypes/symptoms leveraging the depth of the Ingenuity Ontology and the Human Phenotype Ontology *Available for additional cost
