MetabolomicsFecal microbiota transplantation plus anti-PD-1 immunotherapy in advanced melanoma: a phase I trial

Fecal microbiota transplantation (FMT) represents a potential strategy to overcome resistance to immune checkpoint inhibitors in patients with refractory melanoma; however, the role of FMT in first-line treatment settings has not been evaluated. We conducted a multicenter phase I trial combining ...

TranscriptomicsDietary heme alters microbiota and mucosa of mouse colon without functional changes in host-microbe cross-talk.
Colon cancer is a major cause of cancer deaths in Western countries and is associated with diets high in red meat. Heme, the iron-porphyrin pigment of red meat, induces cytotoxicity of gut contents which injures surface cells leading to compensatory hyperproliferation of crypt cells. This hyperproli...

TranscriptomicsMicrobiota facilitates dietary heme-induced epithelial hyperproliferation and hyperplasia by breaking the mucus barrier
Colorectal cancer risk is associated with diets high in red meat. Heme, the pigment of red meat, induces cytotoxicity of colonic contents and elicits epithelial damage and compensatory hyperproliferation, leading to hyperplasia. Here we explore the possible causal role of the gut microbiota in heme-...

Transcriptomics16S rRNA sequencing of cecal microbiota from neonatal mice pre- and post-weaning
Neonatal mice were susceptible to cryptosporidium infection at 1- and 2-weeks of age, but were resistant to infection at 3- and 6-weeks of age. Diet and microbial changes are known to occur during the weaning transition in mice and we hypothesized that these changes in the intestinal luminal environ...

TranscriptomicsEffects of nitric oxide on Salmonella adapted at pH 4.4
Reactive nitrogen species (RNS) derived from dietary and salivary inorganic nitrates (NO3-) foment innate host defenses associated with the acidity of the stomach. The mechanisms by which these reactive species exert antibiotic activity in the gastric lumen are, however, poorly understood. To iden...

MetabolomicsMaternal regulation of biliary disease in neonates via gut microbial metabolites

Maternal seeding of the microbiome in neonates promotes a long-lasting biological footprint, but how it impacts disease susceptibility in early life remains unknown. We hypothesized that feeding butyrate to pregnant mice influences the newborn’s susceptibility to biliary atresia, a severe cholang...
