Gene Network Sciences developed a computational model of human cell proliferation and apoptosis. This network model integrates signaling and gene expression data to predict therapeutic efficacy and patient-specific responses.

Area of Science:

  • Systems biology
  • Computational biology
  • Cellular signaling

Background:

  • Human cell proliferation and apoptosis are complex processes regulated by interconnected signaling and gene expression networks.
  • Understanding these networks is crucial for developing effective therapeutic strategies against diseases like cancer.

Purpose of the Study:

  • To develop a comprehensive network model of human cell proliferation and apoptosis using the Diagrammatic Cell Language.
  • To utilize experimental data to refine the model, identify unknown regulatory interactions, and predict drug target efficacy.

Main Methods:

  • Construction of a network model integrating signal transduction and gene expression pathways.
  • Time-course experiments measuring mRNA and protein activity in Caco-2 and HCT 116 colon cell lines.
