Background:

  • Apoptosis is a critical cellular process regulated by caspases.
  • Optimization principles have been successfully applied to various physiological systems.
  • Previous models have not addressed the optimization of apoptotic biochemical pathways.

Purpose of the Study:

  • To apply optimization principles to apoptotic pathways.
  • To predict procaspase levels based on minimizing protein consumption.
  • To validate a novel optimization model for apoptosis.

Main Methods:

  • Developed an optimization model for apoptotic pathways.
  • Assumed minimization of protein consumption as the core principle.
  • Incorporated known reaction schemes and kinetic constants for apoptosis.
