Application of Sensitivity Analysis to Discover Potential Molecular Drug Targets

Area of Science:

• Systems biology
• Pharmacology
• Computational biology

Background:

• Mathematical modeling is crucial for understanding biological signaling pathways and regulatory networks.
• Sensitivity analysis methods, often adapted from engineering, may not be optimal for biological systems.
• Identifying effective molecular drug targets within complex biological pathways remains a challenge.

Purpose of the Study:

• To develop and present a novel sensitivity analysis method tailored for biological signaling pathways.
• To identify potential molecular targets for drug development within these pathways.
• To facilitate the discovery of active drug components through targeted pharmacological inhibition.

Main Methods:

• Development of a novel sensitivity analysis technique specifically designed for biological systems.
• Application of the method to two established pathway models: the p53/Mdm2 regulatory module and the IFN-β-induced JAK/STAT signaling pathway.
• Evaluation of the method's ability to identify biologically relevant targets through parameter analysis.

Main Results:

• The novel method successfully identified key processes within the tested signaling pathways.
• Biologically relevant conclusions were drawn, highlighting specific molecular interactions for potential drug targeting.
