Environmental sensing, information transfer, and cellular decision-making

CG Bowsher, PS Swain - Current opinion in biotechnology, 2014 - Elsevier
The recognition that gene expression can be substantially stochastic poses the question of
how cells respond to dynamic environments using biochemistry that itself fluctuates. The …

[HTML][HTML] Mathematical modeling of gonadotropin-releasing hormone signaling

A Pratap, KL Garner, M Voliotis… - Molecular and cellular …, 2017 - Elsevier
Gonadotropin-releasing hormone (GnRH) acts via G-protein coupled receptors on pituitary
gonadotropes to control reproduction. These are G q-coupled receptors that mediate acute …

Information transfer by leaky, heterogeneous, protein kinase signaling systems

M Voliotis, RM Perrett, C McWilliams… - Proceedings of the …, 2014 - National Acad Sciences
Cells must sense extracellular signals and transfer the information contained about their
environment reliably to make appropriate decisions. To perform these tasks, cells use signal …

Molecular circuits for dynamic noise filtering

C Zechner, G Seelig, M Rullan… - Proceedings of the …, 2016 - National Acad Sciences
The invention of the Kalman filter is a crowning achievement of filtering theory—one that has
revolutionized technology in countless ways. By dealing effectively with noise, the Kalman …

Stochastic simulation of biomolecular networks in dynamic environments

M Voliotis, P Thomas, R Grima… - PLoS computational …, 2016 - journals.plos.org
Simulation of biomolecular networks is now indispensable for studying biological systems,
from small reaction networks to large ensembles of cells. Here we present a novel approach …

Intrinsic and extrinsic noise of gene expression in lineage trees

P Thomas - Scientific reports, 2019 - nature.com
Cell-to-cell heterogeneity is driven by stochasticity in intracellular reactions and the
population dynamics. While these sources are usually studied separately, we develop an …

Information transmission from NFkB signaling dynamics to gene expression

A Maity, R Wollman - PLoS computational biology, 2020 - journals.plos.org
The dynamic signal encoding paradigm suggests that information flows from the
extracellular environment into specific signaling patterns (encoding) that are then read by …

Uncoupled analysis of stochastic reaction networks in fluctuating environments

C Zechner, H Koeppl - PLoS computational biology, 2014 - journals.plos.org
The dynamics of stochastic reaction networks within cells are inevitably modulated by factors
considered extrinsic to the network such as, for instance, the fluctuations in ribosome copy …

Signaling pathways have an inherent need for noise to acquire information

E Azpeitia, EP Balanzario, A Wagner - BMC bioinformatics, 2020 - Springer
Background All living systems acquire information about their environment. At the cellular
level, they do so through signaling pathways. Such pathways rely on reversible binding …

KL Garner, RM Perrett, M Voliotis, C Bowsher… - Journal of Biological …, 2016 - ASBMB
Cell signaling pathways are noisy communication channels, and statistical measures
derived from information theory can be used to quantify the information they transfer. Here …
