Dynamical Analysis of Yeast Cell Cycle Using a Stochastic Markov Model
Introduction: The cell cycle network is responsible of control, growth and proliferation of cells. The relationship between the cell cycle network and cancer emergence, and the complex reciprocal interactions between genes/proteins calls for computational models to analyze this regulatory network. Ample experimental data confirm the existence of random behaviors in the interactions between gene...

متن کاملStochastic Model of Yeast Cell Cycle Network
Biological functions in living cells are controlled by protein interaction and genetic networks. These molecular networks should be dynamically stable against various fluctuations which are inevitable in the living world. In this paper, we propose and study a stochastic model for the network regulating the cell cycle of the budding yeast. The stochasticity in the model is controlled by a temper...
متن کاملStochastic Modeling of Budding Yeast Cell Cycle
This report presents the definition, solution and validation of a stochastic model of the budding yeast cell cycle, based on Stochastic Petri Nets. A well-established deterministic model, based on ODEs, is considered as the basis for the stochastic modeling. A specific class of Stochastic Petri Nets is selected for building a stochastic version of the deterministic model, with applying the same...
متن کاملStable stochastic dynamics in yeast cell cycle.
Chemical reactions in cells are subject to intense stochastic fluctuations. An important question is how the fundamental physiological behavior of the cell is kept stable against those noisy perturbations. In this study, a stochastic model of the cell cycle of budding yeast was constructed to analyze the effects of noise on the cell-cycle oscillation. The model predicts intense noise in levels ...
