Rule-Based Modeling of Biochemical Systems

From Santa Fe Institute Events Wiki

The use of rules to represent and simulate the interactions of molecules in biochemical regulatory networks [1] is an emerging area of systems biology that promises to change the way these networks are modeled and understood. The purpose of this proposed workshop is to bring together representatives from major research groups active in this area for the purpose of exchanging ideas, discussing applications of rule-based modeling methods, surveying existing capabilities, mapping out where the field is headed, and developing standards that will promote the exchange of models and the development of new software tools. As part of this, one pratical goal will be to discuss and (hopefully) settle on a draft proposal for representing multicomponent species and complexes within the framework of SBML.

Software for Rule-Based Modeling

The objective for this session is to provide an overview of the tools available for rule-based modeling. Key questions for the speakers to address are 1) What biological features and questions motivated the development of the software? 2) What capabilities does the software provide? 3) What are specific examples where the approach/software have led to new insights? 4) What capabilities still need to be developed? 5) What are the essential entities and processes that you feel must be represented in any exchange format to support your modeling needs and software?

One theme for this session and for the whole workshop arises from a more pointed version of Question 3: What results from your work so far make the best case for the necessity of rule-based modeling in this context? How do you respond to the argument that the data doesn't yet justify this sophisticated approach?

Recommended Background Readings

If you have time for nothing else, we strongly recommend reading the following before coming to the meeting:

  • Hlavacek WS, Faeder JR, Blinov ML, Posner RG, Hucka M, Fontana W, Rules for modeling signal-transduction systems, Science STKE, 18 July 2006 PDF. This is a a comprehensive review of rule-based modeling written by the organizers.
  • Kohn, KW, Aladjem, MI, Kim, S, Weinstein, JN, Pommier, Y "Depicting combinatorial complexity with the molecular interaction map notation" Mol Syst Biol 2006 PubMed Abstract

The following are important for the discussions about extending SBML to support this class of modeling:

Travel Information

Santa-fe-google-satellite-view.jpg

The Santa Fe Institute is located in Santa Fe, a small town in New Mexico, USA.

To get to the Santa Fe Institute from outside of New Mexico, you will most likely be flying into Albuquerque International Airport (code: ABQ), which is 60 miles (~100km) away from Santa Fe. It is also possible, though unlikely, that you will fly into the Santa Fe Municipal Airport (code: SAF), but few airlines make connections there. The Santa Fe Institute provides the following useful pages of information about transportation to SFI from ABQ:

The following are some suggestions and recommendations for international visitors:

  • Distances in the western USA are deceptively long (much longer than you may expect from driving in other areas of the world) and the region is sparsely populated. If you are planning on doing any sightseeing, make sure to check your distances carefully.
  • English is the dominant language in Santa Fe. Many residents also speak Spanish.
  • Airport currency exchange services are usually more expensive than taking cash out of an ATM or exchanging at a bank. You may want to check the current exchange rates (e.g., at xe.com) so that you have some idea of what to expect, although of course you will not get the exact exchange rate because all services charge a percentage for doing the exchange.
  • Tipping is customary in the USA and generally not precomputed on bills. 15%-20% is typical and expected for restaurants and taxis, tipping $2-$5 if someone carries your bags or parks your car is also typical, and leaving $2 for the hotel room cleaning staff every day is also appreciated by the staff.
  • You may wish to obtain whatever kind of power adapter is necessary for you to use your laptop and other electrical devices before you arrive into Santa Fe. It may be possible to buy converters at shops around your hotel or elsewhere in Santa Fe, but it is not guaranteed, nor is it assured they will have the right type for your electrical needs. See [3] for information about electric standards in the USA.
