Prominent roles of the NorR and Fur regulators in the Escherichia coli transcriptional response to reactive nitrogen species

Mukhopadhyay, Partha, Zheng, Ming, Bedzyk, Laura A., LaRossa, Robert A., Storz, Gisela

We examined the genomewide transcriptional responses of Escherichia coli treated with nitrosylated glutathione or the nitric oxide (NO)-generator acidified sodium nitrite (NaNO2) during aerobic...

Stationary-Phase Quorum-Sensing Signals Affect Autoinducer-2 and Gene Expression in Escherichia coli

Ren, Dacheng, Bedzyk, Laura A., Ye, Rick W., Thomas, Stuart M., Wood, Thomas K.

Quorum sensing via autoinducer-2 (AI-2) has been identified in different strains, including those from Escherichia, Vibrio, Streptococcus, and Bacillus species, and previous studies have suggested...

Differential Gene Expression To Investigate the Effect of (5Z)-4-Bromo- 5-(Bromomethylene)-3-Butyl-2(5H)-Furanone on Bacillus subtilis

Ren, Dacheng, Bedzyk, Laura A., Setlow, Peter, England, Dacre F., Kjelleberg, Staffan, Thomas, Stuart M., ...

(5Z)-4-Bromo-5-(bromomethylene)-3-butyl-2(5H)-furanone (furanone) from the red marine alga Delisea pulchra was found previously to inhibit the growth, swarming, and biofilm formation of gram-positive...

Differential Gene Expression for Investigation of Escherichia coli Biofilm Inhibition by Plant Extract Ursolic Acid

Ren, Dacheng, Zuo, Rongjun, González Barrios, Andrés F., Bedzyk, Laura A., Eldridge, Gary R., Pasmore, Mark E., ...

After 13,000 samples of compounds purified from plants were screened, a new biofilm inhibitor, ursolic acid, has been discovered and identified. Using both 96-well microtiter plates and a continuous...
