MetabolomicsOmics and Computational Chemistry Reveal Environmental Residues of Anti-COVID-19 Drug Chloroquine Phosphate Drive Antibiotic Resistance Gene Dissemination
The widespread use of chloroquine phosphate (CQP) during the COVID-19 pandemic has led to its persistent residues in aquatic environments, yet its impact on the horizontal transfer of antibiotic resistance genes (ARGs) remains unknown. Herein, the effects and molecular mechanisms of CQP on plasmid-m...

MetabolomicsMulti-omics of the gut microbial ecosystem in the immunotherapy resistance in microsatellite instability-high gastrointestinal cancer patients
Despite the encouraging efficacy of anti-PD-1/PD-L1 immunotherapy in microsatellite instability-high/deficient mismatch repair (MSI-H/dMMR) advanced gastrointestinal cancer, many patients exhibit primary or acquired resistance. Using multi-omics approaches, we interrogated gut microbiome, blood meta...

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 ...

MetabolomicsParabacteroides distasonis ameliorates insulin resistance via activation of intestinal GPR109a
Gut microbiota plays a key role in insulin resistance (IR). Here we perform a case-control study of Chinese adults (ChiCTR2200065715) and identify that Parabacteroides distasonis is inversely correlated with IR. Treatment with P. distasonis improves IR, strengthens intestinal integrity, and reduces ...

MetabolomicsDysregulation of Streptococcus pneumoniae zinc homeostasis breaks ampicillin resistance in a pneumonia infection model

Streptococcus pneumoniae is the primary cause of community-acquired bacterial pneumonia with rates of penicillin and multi-drug resistance exceeding 80% and 40%, respectively. The innate immune response generates a variety of antimicrobial agents to control infection including zinc stres...

MetabolomicsPyruvate availability governs adaptive antibiotic resistance in Staphylococcus aureus
Adaptive resistance enables bacteria to survive antibiotic stress before stable resistance emerges, yet the metabolic requirements that permit this transitional state remain unclear. Using vancomycin-intermediate Staphylococcus aureus (VISA) evolution as a model, we identify pyruvate availability as...

MetabolomicsLactate-driven lysine lactylation mediates high-level colistin resistance in Salmonella
Intracellular pathogens are particularly refractory to antibiotic eradication, leading to persistent and relapsing infections. However, how intracellular metabolic microenvironments shape antibiotic resistance phenotypes remains poorly understood. Here we delineate a metabolic-regulatory axis wherei...

MetabolomicsMicrobial metabolites calibrate innate immunity upon systemic viral infection

Gut microbiome dysbiosis is often associated with immune-mediated diseases. Here, we used germ-free (GF) mice, the synthetic minimal consortium OMM12, and specific pathogen-free (SPF) mice to dissect the causal influence of the microbiome on anti-viral immunity. The lack of microbial diversity af...

MetabolomicsGut Microbial and Metabolic Responses to Salmonella enterica Serovar Typhimurium and Candida albicans

The gut microbiota is increasingly recognized for playing a critical role in human health and disease, especially in conferring resistance to both virulent pathogens such as Salmonella, which infects 1.2 million people in the United States every year [1], and opportunistic pathogens like Candida,...

GenomicsDiabetes induced microbiome dysbiosis is associated with therapy resistance in Pancreatic Ductal Adenocarcinoma (PDAC)
Pancreatic cancer is the 3rd most prevalent cause of cancer related deaths in United states alone, with over 55000 patients being diagnosed in 2019 alone and nearly as many succumbing to it. Late detection, lack of effective therapy and poor understanding of pancreatic cancer systemically contribute...
