Optimal path to epigenetic switching

Phys Rev E Stat Nonlin Soft Matter Phys. 2005 Jan;71(1 Pt 1):011902. doi: 10.1103/PhysRevE.71.011902. Epub 2005 Jan 11.

Abstract

We use large deviation methods to calculate rates of noise-induced transitions between states in multistable genetic networks. We analyze a synthetic biochemical circuit, the toggle switch, and compare the results to those obtained from a numerical solution of the master equation.
