Abstract Gut microbiota‐mediated colonization resistance (CR) is crucial in protecting the host from intestinal infections. Sleep deprivation (SD) an important contributor disturbances of homeostasis. However, whether and how SD affects CR remains largely unknown. Here, it shown that impairs mice, whereas nicotinamide mononucleotide (NMN) supplementation restores it. Microbial diversity metabolomic analyses suggest gut microbiota metabolite profiles SD‐treated mice are highly shaped, NMN...

Tigecycline is a last-resort antibiotic to treat complicated infections caused by multidrug-resistant pathogens, while the emergence of plasmid-mediated tet(X) family severely compromises its clinical efficacy. Novel antimicrobial strategies not limited new antibiotics in pharmaceutical pipeline are urgently needed. Herein, we reveal metabolic disparities between tet(X)-negative and -positive E. coli, including distinct energy demand patterns under tigecycline exposure. In particular,...

Antimicrobial resistance poses a severe threat to human health, with colistin serving as critical medication in clinical trials against multidrug-resistant Gram-negative bacteria. However, the efficacy of is increasingly compromised due rise MCR-positive bacteria worldwide. Here, we reveal notable metabolic disparity between mcr-positive and -negative through transcriptome metabolomics analysis. Specifically, pyridoxal 5'-phosphate (PLP), active form vitamin B6, was significantly diminished...

Circular RNAs (circRNAs) are widely expressed non-coding in eukaryotic cells, involved regulating tumorigenesis of several types cancers. However, the expression profiles and precise functional role glioblastoma remain unclear.Circ-EPB41L5 was downregulated tissues cell lines compared to normal brain lines. Low circ-EPB41L5 correlated poor prognosis patients, while overexpression inhibited proliferation, clone formation, migration, invasion abilities glioma suppression had counter effects....

Background: Lung cancer is the leading source of cancer-caused disability-adjusted life years. Medical cost burden impacts well-being patients through reducing income, cutting daily expenses, curtailing leisure activities, and depleting exhausting savings. The COmprehensive Score for Financial Toxicity (COST) was created validated by De Souza colleagues. Our study intends to measure financial burdens therapy investigate link between toxicity health-related quality (HRQoL) in an advanced lung...

The emergence of antibiotic tolerance, characterized by the prolonged survival bacteria following exposure, in natural bacterial populations, especially pathogens carrying resistance genes, has been an increasing threat to public health. However, major causes contributing formation tolerance and underlying molecular mechanisms are yet poorly understood. Herein, we show that potassium sorbate (PS), a widely used food additive, triggers high level fluoroquinolone mobile colistin gene mcr....

ABSTRACT Antimicrobial resistance is rapidly increasing worldwide, highlighting the urgent need for pharmaceutical and nonpharmaceutical interventions to tackle different-to-treat bacterial infections. Tigecycline, a semi-synthesis glycylcycline parenteral administration, widely recognized as one of few effective therapies available against pan-drug resistant Gram-negative pathogens. Regrettably, efficacy multiple drugs, including tigecycline, currently being undermined due emergence...
