  15. 15. An Alternative Biomedicine Information CommonsCommons are resources that are owned in common or shared amongcommunities. -David Bollier
  16. 16. Why Sage Bionetworks? We believe in a world where biomedical research has changed. It will be conducted in an open, collaborative way where all parties can contribute to making better, faster, relevant discoveries We activate/We challenge We enable others• Diverse collaborations with • Developing platforms for individuals/researchers and collaboration and institutions to collectively engagement – Synapse, grow the biomedical BRIDGE Commons • Defining governance• Crowdsourcing approaches to approaches– PLC challenge the communities We research • Leading biomedical modeling research • Novel training doctoral and internship programs

  18. 18. Governance Technology PlatformImpactful Models Better Models of Disease: INFORMATION COMMONS Challenges
  19. 19. Two recurring problems in Alzheimer’s disease research Ambiguous pathology Are disease-associated molecular systems & genes destructive, adaptive, or both? Bottom line: We need to identify causal factors vs correlative or adaptive features of disease.Diverse mechanismsHow do diverse mutations and environmentalfactors combine into a core pathology?Bottom line: There is no rigorous / consistent globalframework that integrates diverse disease factors. 29
  20. 20. Identifying key disease systems and genes- Gaiteri et al.1.) Identify groups of genes that move together – coexpressed “modules” - correlated expression of multiple genes across many patients - coexpression calculated separately for Disease/healthy groups - these gene groups are often coherent cellular subsystems, enriched in one or more GO functions Example “modules” of coexpressed genes, color-coded
  21. 21. Identifying key disease systems and genes1.) Identify groups of genes that move together – coexpressed “modules”2.) Prioritize the disease-relevance of the modules by clinical and network measures Prioritize modules through expression synchrony with clinical measures or tendency too reconfigure themselves in disease vs
  22. 22. Identifying key disease systems and genes1.) Identify groups of genes that move together – coexpressed “modules”2.) Prioritize the disease-relevance of the modules by clinical and network measures3.) Incorporate genetic information to find directed relationships between genes Infer directed/causal relationships Prioritize modules through expression and clear hierarchical structure by synchrony with clinical measures or tendency too reconfigure themselves in disease incorporating eSNP information (no hair-balls here) vs
  23. 23. Example network finding: microglia activation in ADModule selection – what identifies these modules as relevant to Alzheimer’s disease?The eigengene of a module of ~400 probes correlates with Braak score, age, cognitive disease severityand cortical atrophy. Members of this module are on average differentially expressed (both up- anddown-regulated).Evidence these modules are related to microglia functionThe members of this module are enriched with GO categories (p<.001) such as “response to bioticstimulus” that are indicative of immunologic function for this module.The microglia markers CD68 and CD11b/ITGAM are contained in the module (this is rare – even when amodule appears to represent a specific cell-type, the histological markers may be lacking).Numerous key drivers (SYK, TREM2, DAP12, FC1R, TLR2) are important elements of microglia signaling . Alzgene hits found in co-regulated microglia module:

Figure key:Five main immunologic familiesfound in Alzheimer’s-associatedmoduleSquare nodes in surrounding networkdenote literature-supported nodes.Node size is proportional toconnectivity in the full module.Core family members are shaded.(Interior circle) Width ofconnections between 5immune families arelinearly scaled to thenumber of inter-familyconnections.Labeled nodes are either highlyconnected in the original network,implicated by at least 2 papers asassociated with Alzheimer’s disease,or core members of one of the 5immune families.
