7Background
- NCRR is investigating a potential new resource
that will make it easier for researchers to find
and to use NIH-supported animal and other
biological resources. The initial developmental
focus of the envisioned resource will be a
web-based portal to provide translational
researchers with direct links to the full
spectrum of clinically relevant model systems. - The central component of the portal will be an
animal information service center designed to
enhance processing and retrieval of information
from existing animal model databases into the
forms most appropriate for the target users.
Researchers will be able to tap into various
perspectives on the most recent scientific
knowledge about a problem and combine data of
different types and from multiple sources in ways
that are not currently available. - A second phase proposes to develop technology
that will provide automated ways to optimize,
sustain viability, and enable scalability of this
resource over the longer term.
8Objectives
- The workshop aims to identify potential
architectures and components to serve as the
basis for developing a comprehensive new
resource to describe the user communities and
their needs determine the necessary
characteristics of the new resource and how to
leverage currently available resources and shared
cyberinfrastructure in its creation and ensure
that this translational resource will evolve in
concert with the expanding knowledge in
biomedical science and information technology
that it will embody.
9Reality Check
- Translational Research is
- Poorly Defined Lost in Translation on the Road
Map - Too Visionary (Which is a Bad Thing?)
- Interdisciplinary by Nature
- Therefore Aggravating Culture Clashes
- Study Section Unfriendly
- Technologically Intensive
- Computationally Intensive
- Extremely Expenive Need Innovative Funding
Strategies

14Functional Genomics Approaches To Study Viral
Host Interactions
- The human (mouse, rat, etc.) genome is completely
sequenced. - Rhesus Macaque Genome Is Done!
- Global transcriptional profiling is possible.
- Proteomics becoming high-throughput.
- Computational biology sufficiently mature to
interpret massive data sets.

On Macaque Arrays
- 18,000 unique (Rhesus) macaque genes
- 1,014 human oligonucleotides relevant to
infectious disease research - 51 viral genes (from 20 viruses)
- High degree of genetic similarity between rhesus

- To define the complete host response at the RNA
and protein level to every virus infection - To identify impacted pathways in common
- To identify unique pathways
- To cure all virus infections (with one drug?)
- To uncover links between virus infections and
other diseases e.g. malignancy - Almost 6000 array experiments in our database
43Breakout Group Questions
- 1. Who are the intended and potential users of
the new resource? What tasks are they performing
and what are their needs, particularly in
translational science? - 2. What are the characteristics of this new
resource that will best serve the users needs? - 3. What framework for animal model systems is
most appropriate to serve as the basis for this
new resource that will also support later
development? Possibilities might include one or
more disease categories, body or organ systems or
tissues, etc. - 4. How can currently available resources and
distributed systems information technology
projects be leveraged to develop the new shared
infrastructure? - 5. What are the requirements of a
cyberinfrastructure framework for animal model
systems that are most critical in order to
provide a foundation for this new resource that
will also support rapid technological elaboration
and expanded use?
