Epigenetics as a first exit problem
, 2001 We develop a framework to discuss stability of epigenetic states as first exit problems in dynamical systems with noise. We consider in particular the stability of the lysogenic state of the lambda prophage, which is known to exhibit exceptionally large ...

DNA looping provides stability and robustness to the bacteriophage lambda switch [PDF]
, 2009 The bistable gene regulatory switch controlling the transition from lysogeny to lysis in bacteriophage lambda presents a unique challenge to quantitative modeling. Despite extensive characterization of this regulatory network, the origin of the extreme stability of the lysogenic state remains unclear.

Calculating Biological Behaviors of Epigenetic States in Phage lambda Life Cycle
, 2004 Gene regulatory network of lambda phage is one the best studied model systems in molecular biology. More 50 years of experimental study has provided a tremendous amount of data at all levels: physics, chemistry, DNA, protein, and function.

Comparative study of adenosine 3′‐pyrophosphokinase domains of MuF polymorphic toxins
FEBS Open Bio, EarlyView.With the ultimate goal of understanding the association of toxin‐immunity modules to temperate phages, we characterized toxins from three prophages and examined cross‐protection from immunity proteins. The toxins exhibit adenosine 3′‐pyrophosphokinase activity and are toxic in Escherichia coli.

Transcriptional delay stabilizes bistable gene networks
, 2013 Transcriptional delay can significantly impact the dynamics of gene networks. Here we examine how such delay affects bistable systems. We investigate several stochastic models of bistable gene networks and find that increasing delay dramatically ...

Sonochemical Functionalization of Glass
Advanced Functional Materials, EarlyView.A new method for functionalizing glass using ultrasonication of aryl diazonium salts. Aryl radicals generated by ultrasounds react with glass, forming a stable, covalently bonded organic film. The functionalized glass adheres microorganisms such as microalgae, fungi, and bacteria, suggesting potential applications in enzyme production, filtration ...

Lysogen stability is determined by the frequency of activity bursts from the fate‐determining gene
Molecular Systems Biology, 2010 The ability of living cells to maintain an inheritable memory of their gene‐expression state is key to cellular differentiation. Bacterial lysogeny serves as a simple paradigm for long‐term cellular memory.
