Internal and external fluctuations are ubiquitous in cellular signaling processes. Because biochemical reactions often evolve on disparate time scales, mathematical perturbation techniques can be invoked to reduce the complexity of stochastic models. Previous work in this area has focused on direct treatment of the master equation. However, eliminating fast variables in the chemical Langevin equation is also an important problem. We show how to solve this problem by utilizing a partial…

Stochastic Delay Accelerates Signaling in Gene Networks

In an analytically tractable model, increasing the randomness in protein production delay can increase signaling speed in transcriptional networks and show that in feedforward loops signaling time and magnitude are significantly affected by distributed delay.

Channel based generating function approach to the stochastic Hodgkin-Huxley neuronal system

A generating function approach is applied to the master equation for the ion channel dynamics and two accelerating algorithms are proposed, with an accuracy close to the Gillespie algorithm but with much higher efficiency, opening the door for expedited simulation of noisy action potential propagating along axons or other types of noisy signal transduction.

A variational approach to the stochastic aspects of cellular signal transduction.

This work shows how to achieve tremendous reduction in the dimensionality of specific reaction cascade dynamics by solving variationally an equivalent quantum field theoretic formulation of stochastic chemical kinetics.

Eliminating fast reactions in stochastic simulations of biochemical networks: a bistable genetic switch.

It is found that protein-protein interactions may be safely eliminated from the reaction set, but protein-DNA interactions may not, and it is important to use the chemical master equation rather than macroscopic rate equations to compute effective propensity functions for the coarse-grained reactions.

The interplay between discrete noise and nonlinear chemical kinetics in a signal amplification cascade.
