MetabolomicsCollected mass spectrometry data on monoterpene indole alkaloids from natural product chemistry research
MIADB: a cumulative collection of 172 tandem mass spectrometry (MS/MS) of a vast array of monoterpene indole alkaloids. Samples were analyzed using an Agilent LC-MS system composed of an Agilent 1260 Infinity HPLC coupled to an Agilent 6530 ESI-Q-TOF-MS operating in positive mode. A Sunfire analytic...

MetabolomicsLimosilactobacillus reuteri with indole-3-lactic acid-producing capacity protects against atherosclerosis by fortifying the gut-vascular barrier

Introduction: The gut microbiota and its metabolites are implicated in atherosclerosis, but the specific effector molecules and their pathophysiological significance remain unclear.

Objectives: This study aimed to identify key atheroprotective microbial metabolites and to elucidate the mech...

TranscriptomicsHuman epithelial cell response to bacterial signal indole
Indole is a bacterial signal secreted by pathogenic and commensal Escherichia coli in the stationary phase at high concentrations (~600 µM). Prior work from our lab has shown that indole decreases E. coli O157:H7 (EHEC) chemotaxis, motility, attachment to epithelial cells and biofilm formation. How...

MetabolomicsLacto-N-tetraose mediates indole-3-lactic acid production by Bifidobacterium longum subsp. infantis to alleviate enterotoxigenic Escherichia coli-induced diarrhea in infants

Enterotoxigenic Escherichia coli (ETEC) is a leading cause of infectious diarrhea and poses a threat to infant health. Current treatments for ETEC infection primarily rely on antibiotics，which face limitations due to resistance and side effect. In this cross-sectional study, we analyzed fecal met...

ProteomicsEmhR is an indole-sensing transcriptional regulator responsive for the indole-induced antibiotic tolerance in Pseudomonas fluorescens
Indole is ubiquitously synthesized by plants and bacteria and functions as an inter species signaling molecule to modulate a wide variety of cellular activities. However, it is not clear how the indole signal is perceived and responded by plant growth promoting rhizobacteria (PGPR) at the rhizospher...

MetabolomicsMild cold exposure mitigates ischemic heart injury through indole-3-acetamide–AHR-mediated SMAD2 proteolysis

Ambient temperature profoundly influences organismal metabolism, physiology, and disease. While cold exposure is a well-recognized risk factor for the onset of myocardial infarction (MI), its impact on the injured heart after MI remains unexplored. Here,&nb...

MetabolomicsThe Formation of Phenol and Indole Flavor Substances in Stinky Tofu Brine Based on Metabolism of Aromatic Amino Acids

Understanding the formation mechanism of the flavor compounds in stinky tofu brine is crucial for controlling the flavor quality of Changsha stinky tofu. Dynamic changes in associated bacteria, enzymes, and differential metabolites in the metabolic pathway of aromatic amino acids in brine were in...

TranscriptomicsTranscription profiling of E.coli reveals indole cell signaling occurs primarily at low temperatures in Escherichia coli
We have shown the quorum-sensing signals acylhomoserine lactones (AHLs), autoinducer-2 (AI-2), and indole influence the biofilm formation of Escherichia coli. Here, we investigate how the environment, i.e., temperature, affects indole and AI-2 signaling in E. coli. We show in biofilms that indole a...

MetabolomicsMicrobiota-derived p-cresol and indole metabolites mediates neurotoxic gut-brain axis dysregulation in ALS
Integrated metabolomic profiling demonstrated a marked increase in microbiota-derived metabolites, particularly along aromatic amino acid pathways. Notably, p-cresol metabolites were significantly elevated in both brain and circulation, suggesting enhanced microbial phenylalanine/tyrosine metabolism...

MetabolomicsBacteroides uniformis degrades β-glucan to promote Lactobacillus johnsonii improving indole-3-lactic acid levels in alleviating colitis

The gut microbiota plays a crucial role in the onset and progression of inflammatory bowel disease (IBD). β-glucan (BG), a soluble dietary fiber widely present in oats, barley, fungi, yeast and some bacteria, has multiple bioactive properties such as mitigating intestinal inflammation; however, t...
