Computational models for gene regulatory networks integrate genetic logic and real-time dynamics. These models reveal network architecture, aiding testable predictions for developmental gene systems.

Area of Science:

  • Developmental Biology
  • Computational Biology
  • Systems Biology

Background:

  • Gene network analysis requires models of regulatory interactions.
  • Developmentally active cis-regulatory systems process diverse inputs into novel outputs.
  • Existing models can be extended to represent complex developmental gene networks.

Purpose of the Study:

  • To develop computationally based models for gene network analysis.
  • To represent the functional architecture of regulatory interactions and provide testable predictions.
  • To accommodate the processing of diverse regulatory inputs and generation of novel outputs.

Main Methods:

  • Developing computational models that represent genetically mandated logic functions.
  • Incorporating time-varying kinetic inputs and outputs.
Keywords:
Non-programmatic

  • Utilizing cis-regulatory element target site sequences as the physical basis for network architecture.

    • Main Results:

    • A computational model was developed for the sea urchin endo16 gene cis-regulatory system.
    • The model represents genetic logic and the processing of kinetic inputs/outputs.
    • The design features can be applied to construct models for larger developmental gene networks.

    Conclusions:

    • Network models must represent genetic logic and real-time dynamics.
    • Models should transparently display network design features like feedback and input sources.
    • Successful models facilitate direct testing of architectural features through cis-regulatory analysis.
