随机反应网络中受约束稳态分布参数域的代数计算方法

An algebraic method to calculate parameter regions for constrained steady-state distribution in stochastic reaction networks

Tan Van Vu, Yoshihiko Hasegawa

摘要:

稳态是反应网络中的一个基本概念。它的稳定性反映了细胞信号转导和基因表达等生物学现象的基本特征。由于生化反应发生在细胞水平,它们受到不可避免的波动的影响。虽然已经提出了几种方法来检测和分析确定性模型的稳态稳定性,这些方法不能应用于随机反应网络。本文提出了一种基于代数计算的随机反应网络约束稳态分布参数域的算法,其中均值和方差满足给定的不等式约束。为了评估我们提出的方法,我们进行了计算机模拟的三个典型的化学反应,并证明我们的方法得到的结果与模拟结果是一致的。

英文摘要:

Steady state is an essential concept in reaction networks. Its stability reflects fundamental characteristics of several biological phenomena such as cellular signal transduction and gene expression. Because biochemical reactions occur at the cellular level, they are affected by unavoidable fluctuations. Although several methods have been proposed to detect and analyze the stability of steady states for deterministic models, these methods cannot be applied to stochastic reaction networks. In this paper, we propose an algorithm based on algebraic computations to calculate parameter regions for constrained steady-state distribution of stochastic reaction networks, in which the means and variances satisfy some given inequality constraints. To evaluate our proposed method, we perform computer simulations for three typical chemical reactions and demonstrate that the results obtained with our method are consistent with the simulation results.
