Interkingdom signaling is established in the gastrointestinal tract in that human hormones
trigger responses in bacteria; here, we show that the corollary is true, that a specific bacterial …

Background As a stationary phase signal, indole is secreted in large quantities into rich medium
by Escherichia coli and has been shown to control several genes (eg, astD, tnaB, gabT), …

Communication between bacteria, belonging to the same species or to different species, is
mediated through different chemical signals that are synthesized and secreted by bacteria. …

The gut microbiota plays a significant role in the progression of fatty liver disease; however,
the mediators and their mechanisms remain to be elucidated. Comparing metabolite profile …

During infection in the gastrointestinal tract, enterohemorrhagic Escherichia coli (EHEC)
O157:H7 is exposed to a wide range of signaling molecules, including the eukaryotic hormones …

The tryptophan metabolites indole, indole-3-acetate, and tryptamine were identified in mouse
cecal extracts and fecal pellets by mass spectrometry. The aryl hydrocarbon receptor (AHR…

Metabolites produced by the intestinal microbiota are potentially important physiological
modulators. Here we present a metabolomics strategy that models microbiota metabolism as a …

Since indole is present at up to 500 μM in the stationary phase and is an interspecies biofilm
signal (J. Lee, A. Jayaraman, and TK Wood, BMC Microbiol. 7:42, 2007), we investigated …

The dynamics of gene expression are fundamental to the coordination of cellular responses.
Measurement of temporal gene expression patterns is currently limited to destructive low-…

To utilize biofilms for chemical transformations in biorefineries they need to be controlled
and replaced. Previously, we engineered the global regulator Hha and cyclic diguanylate-…
