Quorum sensing influences Vibrio harveyi growth rates in a manner not fully accounted for by the marker effect of bioluminescence.

PLoS ONE, 2008
BackgroundThe light-emitting Vibrios provide excellent material for studying the interaction of cellular communication with growth rate because bioluminescence is a convenient marker for quorum sensing.

Exploring the Role of Stent Strut Geometry in Cellular Behavior: An In Vitro Chip Model to Understand In‐Stent Restenosis

Advanced Materials Interfaces, EarlyView.
An engineered in vitro platform mimicking stent strut cross‐sectional shapes reveals how geometry influences cell behavior. Sharp‐cornered geometries promote cell proliferation and matrix alignment, while rounded shapes reduce these effects. The findings align with clinical outcomes and suggest intracellular tension as a key driver, offering a ...

The Potential of Secondary Metabolites in Medicinal Plants as Anti–Quorum Sensing in Biofilms: A Comprehensive Review

Journal of Chemistry
The formation of biofilms occurs due to a group of bacteria gathering together. The increasing of cell density will stimulate chemical signals for bacteria to communicate through quorum sensing system.

Reversible Signal Binding by the Pseudomonas aeruginosa Quorum-Sensing Signal Receptor LasR

mBio, 2011
Many members of the LuxR family of acyl-homoserine lactone (acyl-HSL)-dependent quorum-sensing transcriptional activators are thought to have the unusual characteristics of requiring the signal ligand during polypeptide synthesis to fold into an active ...

Synergy of Quorum Quenching Enzyme and Quorum Sensing Inhibitor in InhibitingP.aeruginosaQuorum Sensing [PDF]

, 2017
ABSTRACTThe threat of antibiotic resistant bacteria has called for alternative antimicrobial strategies that would mitigate the increase of classical resistance mechanism. Many bacteria employ quorum sensing (QS) to govern the production of virulence genes and formation of drug-resistance biofilms.

Self‐Adjusting Engineered Probiotic for Targeted Tumor Colonization and Local Therapeutics Delivery

Advanced Science, EarlyView.
Zou et al. developed an engineered strain of Escherichia coli Nissle 1917 with precise targeting abilities for colonization and on‐demand payload release. The engineered probiotic survives and embolizes tumors only in the presence of more than 5 mM L‐lactate. Furthermore, the introduction of an α‐hemolysin circuit enhances its anti‐tumor effect.

The natural furanone (5Z)-4-bromo-5-(bromomethylene)-3-butyl-2(5H)-furanone disrupts quorum sensing-regulated gene expression in Vibrio harveyi by decreasing the DNA-binding activity of the transcriptional regulator protein luxR [PDF]

, 2007
This study aimed at getting a deeper insight in the molecular mechanism by which the natural furanone (5Z)-4-bromo-5-(bromomethylene)-3-butyl-2(5H)- furanone disrupts quorum sensing in Vibrio harveyi.

Negative regulation of violacein biosynthesis in Chromobacterium violaceum [PDF]

, 2017
In Chromobacteium violaceum, the purple pigment violacein is under positive regulation by the N-acylhomoserine lactone CviI/R quorum sensing system and negative regulation by an uncharacterized putative repressor.
