    Notes on slide 1

    Multiple comparisons are necessary To be useful as a general diagnostic, signature markers should not be mouse strain or prion strain specific and should not be induced in Prnp0 mice To make this work the amount of data acquired and analyzed is very large – most researchers underestimate this aspect of systems approaches.

    There are four common features in the neuropathology of prion diseases. They are: Replication and accumulation of prion proteins Activation of microglia and astrocytes Degeneration of synapse And, cell death with spongiform phenotype.

    Need to emphasize Lee H’s signal to noise issues for each of these points Need to emphasize Lee Hood’s signal to noise advantage We’re now in a position to do genetics the way it used to be done New technologies--coverage and error Variations/recombination--I.e. the unit is the pedigree, not just the genome (Jared’s point) Disease--use the inheritance patterns (consistency) to narrow down list of candidates The idea here is to emphasize what one can uniquely do for a family

    Suttonian / Vriesian analysis figure. Just showing cross-over points and inheritance patterns now. It seems worthwhile at least indicating the locations of the centromeres. Also, the color-code can be better by showing the “intermediate phases (sea grean and dark blue) as divided blocks (one example given on top of chr 1).

    This is a slide that lays out in a simple fashion the fundamental ideas.

    Medicine of the Future—The Transformation from Reactive to Proactive (P4) Medicine - Presentation Transcript

    1. Medicine of the Future—The Transformation from Reactive to Proactive (P4) Medicine Predictive, Personalized, Preventive and Participatory Lee Hood Institute for Systems Biology, Seattle
    2. The Current Healthcare Debate
      • The debate is centered on medicine of the past/present rather than medicine of the future
      • Healthcare is a fundamental right of all citizens. When viewed in the context of medicine of the present--current health care is ineffective, costly and therefore impossible to extend to all citizens
      • The healthcare debate today is about rationing and who will be left out or poorly served
      • The key is to understand medicine of the near future (P4 medicine) and realize the transformation it will bring—an effectiveness and reduced cost—ultimately with the possibility of bringing adequate healthcare to all
    3. Contemporary Systems Biology is Predicated on Viewing Biology is an Informational Science
      • The digital information of the genome
      There are two types of Biological Information
      • The environmental information that impinges upon and modifies the digital information.

      • Challenges
        • Data standaridized
        • Universally accepted IT healthcare system to store, analyze, transmit, integrate and model data--no current system adequate
        • Data available in an integrateable mode to analytic labs
        • Biobanks for tissue and blood storage from individuals
        • Ethics, social, legal, regulatory, economic issues resolved
        • Deep research support for P4-oriented medicine to hasten its realization
    65. The Conclusion
      • The current debate on healthcare is centered on medicine of the past—and hence misses the enormous potential of medicine of the future (P4) for revolutionary change.
      • Siloization with many different medical systems with different IT for healthcare, no data standardization, no effective biobanks for sample storage and no agreement on ethical, policy, societal, economic issues would be a disaster—integrative challenges
      • Is the only the government in a position to handle the effective integrative challenges of P4 medicine?
    66. The P4 Medical Institute Through the ISB/OSU Strategic Partnership Could Play a Key Role in Accelerating the Emergence of P4 Medicine
