W Abou-Jaoudé, M Chaves, JL Gouzé - PLOS one, 2011 - journals.plos.org
Experimental observations performed in the p53-Mdm2 network, one of the key protein
modules involved in the control of proliferation of abnormal cells in mammals, revealed the …

From structure to dynamics: frequency tuning in the p53–mdm2 network: I. logical approach

W Abou-Jaoudé, DA Ouattara, M Kaufman - Journal of theoretical biology, 2009 - Elsevier
We investigate the dynamical properties of a simple four-variable model describing the
interactions between the tumour suppressor protein p53, its main negative regulator Mdm2 …

From structure to dynamics: Frequency tuning in the p53-Mdm2 network. II: Differential and stochastic approaches

DA Ouattara, W Abou-Jaoudé, M Kaufman - Journal of theoretical biology, 2010 - Elsevier
In Part I of this work, we carried out a logical analysis of a simple model describing the
interplay between protein p53, its main negative regulator Mdm2 and DNA damage, and …

Spatio-temporal modelling of the p53–mdm2 oscillatory system

KE Gordon, IMM Van Leeuwen, S Lain… - … Modelling of Natural …, 2009 - cambridge.org
In this paper we investigate the role of spatial effects in determining the dynamics of a

Oscillations by the p53-Mdm2 feedback loop

G Lahav - Cellular Oscillatory Mechanisms, 2008 - Springer
The p53 network is perhaps the most important pathway involved in preventing the initiation
ofcancer. p53levels and activity are upregulated in response to various stresses including …

Negative feedback dynamics and oscillatory activities in regulatory biological networks

S Yan - Journal of Biological Systems, 2007 - World Scientific
The recent experiments on the dynamics of a common biological network motif, p53 and
Mdm2 feedback loop, have shown the oscillatory behaviors for the activities of p53 and …

Another turn for p53

JJ Tyson - Molecular Systems Biology, 2006 - embopress.org
The tumor suppressor protein, p53, is a major guardian of genomic integrity in human cells
(Hanahan and Weinberg, 2000). When DNA is damaged by ionizing radiation (as a result …

Steady states and oscillations in the p53/Mdm2 network

A Ciliberto, B Novák, JJ Tyson - Cell cycle, 2005 - Taylor & Francis
p53 is activated in response to events compromising the genetic integrity of a cell. Recent
data show that p53 activity does not increase steadily with genetic damage but rather …

We previously proposed an integrated computational model for the network of cyclin-
dependent kinases (Cdks) that controls the dynamics of the mammalian cell cycle [C. Gérard …

Analysis of a minimal model for p53 oscillations

S Bottani, B Grammaticos - Journal of Theoretical Biology, 2007 - Elsevier
Oscillatory behaviours in genetic networks are important examples for studying the
principles underlying the dynamics of cellular regulation. Recently the team of Alon has …
