Dissecting specific and global transcriptional regulation of bacterial gene expression
Molecular Systems Biology, 2013 Gene expression is regulated by specific transcriptional circuits but also by the global expression machinery as a function of growth. Simultaneous specific and global regulation thus constitutes an additional—but often neglected—layer of complexity in ...

Post-transcriptional regulation of gene expression in bacterial pathogens by toxin-antitoxin systems [PDF]
Frontiers in Cellular and Infection Microbiology, 2014 Toxin-antitoxin (TA) systems are small genetic elements ubiquitous in prokaryotic genomes that encode toxic proteins targeting various vital cellular functions.

Status quo of tet regulation in bacteria
Microbial Biotechnology, 2022 Summary The tetracycline repressor (TetR) belongs to the most popular, versatile and efficient transcriptional regulators used in bacterial genetics. In the tetracycline (Tc) resistance determinant tet(B) of transposon Tn10, tetR regulates the expression

Mode of Regulation and the Insulation of Bacterial Gene Expression [PDF]
Molecular Cell, 2012 A gene can be said to be insulated from environmental variations if its expression level depends only on its cognate inducers, and not on variations in conditions. We tested the insulation of the lac promoter of E. coli and of synthetic constructs in which the transcription factor CRP acts as either an activator or a repressor, by measuring their input

Algorithm for the Reconstruction of Mathematical Frame Models of Bacterial Transcription Regulation
Mathematics, 2022 Transcription regulation plays an important role in bacterial activity. The operon concept coined by François Jacob and Jacques Monod has had a considerable effect on investigations into gene expression regulation, including modeling.

Journal of Microbiology & Biology Education, 2021 Practical lab exercises that help students draw connections between genotype and phenotype, and make and test predictions about the identity of mutants, are invaluable in college-level cell biology, genetics, and microbiology courses. While many bacteria

Epigenetic silencing of host cell defense genes enhances intracellular survival of the rickettsial pathogen Anaplasma phagocytophilum. [PDF]
PLoS Pathogens, 2009 Intracellular bacteria have evolved mechanisms that promote survival within hostile host environments, often resulting in functional dysregulation and disease.

The BvgAS Regulon of
mBio, 2017 Nearly all virulence factors in Bordetella pertussis are activated by a master two-component system, BvgAS, composed of the sensor kinase BvgS and the response regulator BvgA.
