MecCog

MecCog represents genetic disease mechanisms as integrated, evidence-linked mechanism schemas mapping how genetic variants and perturbed biological entities and activities propagate across stages of biological organization to produce disease phenotypes.


Key Features:

  • Integrated Mechanism Schemas: Constructs graphical mechanism schemas that map propagation of system perturbations from genetic variants to disease phenotypes across stages of biological organization.
  • Graphical Notations and Hyperlinked Evidence Tagging: Uses formal graphical notations to represent perturbed entities and activities and attaches hyperlinked evidence tags that link schema elements to specific experimental data.
  • Mechanism Ontology: Applies a mechanism ontology to standardize representation of biological processes and interactions within schemas.
  • Depiction of Knowledge Gaps and Uncertainties: Explicitly marks knowledge gaps, ambiguities, and uncertainties within mechanism representations to indicate areas requiring further investigation.
  • Integration of Diverse Mechanistic Data Sources: Integrates mechanistic information from diverse formats and sources, including unstructured text, pathway diagrams, and network graphs, into unified schemas.
  • Annotation of Perturbed Entities, Activities, and Interactions: Annotates specific biological entities, molecular activities, and interactions within schemas to support mechanistic interpretation.

Scientific Applications:

  • Biomarker and Therapeutic Target Identification: Maps critical perturbation points to support identification of potential biomarkers and therapeutic intervention sites.
  • Hypothesis Generation and Validation: Integrates diverse mechanistic evidence into coherent schemas to facilitate generation and validation of mechanistic hypotheses.
  • Prioritization of Experimental Investigation: Highlights gaps and uncertainties to prioritize areas for further experimental study.
  • Standardization and Synthesis of Mechanistic Knowledge: Uses ontology-backed schemas to enable consistent representation and comparison of mechanisms across studies.

Methodology:

Systematic integration of mechanistic information from various sources into a unified graphical format, annotation of perturbed biological entities, activities, and interactions with hyperlinked evidence tagging, and application of a mechanism ontology to standardize representations.
