The Role of Bacteriophage-Derived Small RNA Molecules in Bacterial and Phage Interactions [PDF]
Small regulatory RNAs (sRNAs) play a critical role in bacterial gene expression, modulating various cellular processes, including stress responses, metabolism, virulence, and many others.

Dissecting specific and global transcriptional regulation of bacterial gene expression
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]
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
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]
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
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.

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]
Intracellular bacteria have evolved mechanisms that promote survival within hostile host environments, often resulting in functional dysregulation and disease.
