TranscriptomicsDepletion of murine intestinal microbiota: effects on gut mucosa and epithelial gene expression
Inappropriate cross talk between mammals and their gut microbiota may trigger intestinal inflammation and drive extra-intestinal immune-mediated diseases. Studies with germ-free or gnotobiotic animals represent the gold standard for research on bacterial-host interaction but they are not readily acc...

MetabolomicsAge-related differences in the gut microbiota and plasma metabolome in dogs: a prospective cross-sectional study under standardized dietary conditions
Background: Aging is associated with progressive metabolic and physiological changes that influence health span in humans and may similarly impact dogs. This study aimed to characterize in the gut microbiota and their associations with host metabolism. Client-owned young adult (2-5 years, > 20 kg, n...

GenomicsSaliva microbiota in Finnish children
The human intestinal microbiota may play a role in the development of overweight and obesity. However, associations between saliva microbiota and body mass index (BMI) have been sparsely studied, although the oral cavity is the major gateway for microbes into the body. The aim of this study was to i...

Genomics16S sequencing of gut microbiota in healthy individuals from different regions
In this study we investigated whether gut microbiota profile of Italian healthy volunteers could differ based on their geaographical origin. To this purpose, fecal samples were collected from 31 healthy individuals living in 3 different italian regions (Lombardy, North; Lazio, Center; Apulia, South)...

MetabolomicsFaecal microbiota transplant from aged donor mice affects spatial learning and memory via modulating hippocampal synaptic plasticity- and neurotransmission-related proteins in young recipients

BACKGROUND: The gut-brain axis and the intestinal microbiota are emerging as key players in health and disease. Shifts in intestinal microbiota composition affect a variety of systems, however, evidence of their direct impact on cognitive functions is still lacking. We tested whe...

MetabolomicsPaeonol Ameliorates Ulcerative Colitis in Mice by Modulating the Gut Microbiota and its Metabolites

BACKGROUND: Ulcerative colitis (UC) is a chronic recurrent inflammatory disease of the gastrointestinal tract. Recent studies demonstrate that the phenolic tannin paeonol (Pae) attenuates UC in mouse models by downregulating inflammatory factors; however, molecular mechanisms lin...

TranscriptomicsMaternal cecal microbiota transfer rescues early-life antibiotic-induced enhancement of type 1 diabetes in mice-the long term restoration
Early-life antibiotic exposure perturbs the intestinal microbiota, alters innate intestinal immunity, and accelerates type 1 diabetes development in the NOD mouse model. Here we found that maternal cecal microbiota transfer (CMT) to NOD mice with early-life antibiotic perturbation partially rescued ...

MetabolomicsMulti-kingdom gut microbiota dysbiosis is associated with the development of pulmonary arterial hypertension

Gut microbiota dysbiosis has been implicated in pulmonary arterial hypertension (PAH). However, most studies have focused on the bacterial community and the exact role and mechanisms of multi-kingdom gut microbiota, including bacteria, archaea and fungi in PAH remains largely unclear. Idiopathic ...

MetabolomicsEffect of gut microbiota on depressive-like behaviors in mice is mediated by the endocannabinoid system

Depression is the leading cause of disability worldwide. Recent observations have revealed an association between mood disorders and alterations of the intestinal microbiota, but causality remains yet to be established. Here, using unpredictable chronic mild stress (UCMS) as a mouse mod...
