Dynamical properties and path dependence in a gene-network model of cell differentiation

Abstract: In this work, we explore the properties of a control mechanism exerted on random Boolean networks that takes inspiration from the methylation mechanisms in cell differentiation and consists in progressively freezing (i.e. clamping to 0) some nodes of the network. We study the main dynamical properties of this mechanism both theoretically and in simulation. In particular, we show that when applied to random Boolean networks, it makes it possible to attain dynamics and path dependence typical of biological cells… Show more

“…Finally, in light of the great complexities posed by the path-dependent nature of the online adaptation process [ 20 , 48 , 49 ], we conclude that a mechanism such as the one we have introduced might be an effective tool for tuning artificial systems to the specific environment in which they have to operate. As a futuristic application, we imagine the construction of miniaturized robots that can accomplish missions precluded to humans, such as recovering polluted environments.…”

“…Since their inception as an abstract model of gene regulatory networks [ 14 ], Boolean networks (BNs) have been the subject of a wealth of works investigating their computational and dynamical properties. Notably, BNs have demonstrated their ability to effectively capture significant biological phenomena, such as cell differentiation [ 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. Evidence of an edge provided by critical Boolean networks has been demonstrated in classification, filtering and control tasks, just to mention some examples.…”

“…This special issue includes seven peer-reviewed articles about synthetic biology, whose aim is to develop formal models for biological-like phenomena, specially in the context of molecular logic (Djordević and Silva 2019;Nemati and Torres 2020;Santiago et al 2020;Braccini et al 2020;Moreira et al 2020;Tavares et al 2021;Veloz and Flores 2021). Molecular logic focuses on understanding logical and operational aspects on molecules and their interactions, providing a fruitful conceptual crossover between chemistry and computation with unsuspected applications.…”

“…The aim of MLSCB18 was harnessing logical and algebraic methods for modeling and verifying systems on the interaction of Nature and Computation, around two main themes, which can also serve to split the list of articles published in this special issue: The development of biological computation models and devices (Djordević and Silva 2019;Braccini et al 2020;Tavares et al 2021;Veloz and Flores 2021), and the application of new computing paradigms to the design of biological systems (Nemati and Torres 2020;Santiago et al 2020;Moreira et al 2020).…”
