The bacterial signal molecule, ppGpp, regulates Salmonella virulence gene expression [PDF]
Molecular Microbiology, 2004 SummaryNumerous, overlapping global regulatory systems mediate the environmental signalling controlling the virulence of Salmonella typhimurium. With both extra‐ and intracellular lifestyles, unravelling the mechanisms involved in regulating Salmonella pathogenesis has been complex.

Biofilm-stimulated epithelium modulates the inflammatory responses in co-cultured immune cells [PDF]
, 2019 The gingival epithelium is a physical and immunological barrier to the microbiota of the oral cavity, which interact through soluble mediators with the immune cells that patrol the tissue at the gingival epithelium.

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes
FEBS Letters, EarlyView.Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

FEBS Letters, EarlyView.Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...

A sigma factor toolbox for orthogonal gene expression in Escherichia coli [PDF]
, 2018 Synthetic genetic sensors and circuits enable programmable control over timing and conditions of gene expression and, as a result, are increasingly incorporated into the control of complex and multi-gene pathways.

FEBS Letters, EarlyView.Mutations in the C9orf72 gene represent the most common genetic cause of amyotrophic lateral sclerosis (ALS), a fatal neurodegenerative disease. Using patient‐derived neurons and C. elegans models, we find that the nucleoporin Nup107 is dysregulated in C9orf72‐associated ALS. Conversely, reducing Nup107 levels mitigates disease‐related changes.

A Prophage-Encoded Small RNA Controls Metabolism and Cell Division in
mSystems, 2016 Hundreds of small RNAs (sRNAs) have been identified in diverse bacterial species, and while the functions of most remain unknown, some regulate key processes, particularly stress responses.

Nitric oxide mediates antimicrobial peptide gene expression by activating eicosanoid signaling. [PDF]
PLoS ONE, 2018 Nitric oxide (NO) mediates both cellular and humoral immune responses in insects. Its mediation of cellular immune responses uses eicosanoids as a downstream signal.
