MetabolomicsGPR109a-AMPK Axis Mediates the Attenuation of Uric Acid-Induced M1 Macrophage Polarization by β-hydroxybutyrate from Lacticaseibacillus rhamnosus M2b

Hyperuricemia (HUA) is a metabolic disorder marked by increased blood uric acid (UA) levels, closely linked to conditions such as gout. UA-induced macrophage M1 polarization fundamentally exacerbates inflammatory pathophysiology, but current HUA-specific immunoregulatory treatments are inadequat...

MetabolomicsUntargeted metabolomic analysis in cats with naturally occurring inflammatory bowel disease and alimentary small cell lymphoma
Feline chronic enteropathy (CE) is a common gastrointestinal disorder in cats and mainly comprises inflammatory bowel disease (IBD) and small cell lymphoma (SCL). Differentiation between IBD and SCL can be diagnostically challenging. We characterized the fecal metabolome of 14 healthy cats and 22 ca...

MetabolomicsGut Commensal Bacteria-Derived Methionine is Required for Host Reproduction by Modulating RNA m6A Methylation of the Insulin Receptor_targeted metabolites

Gut commensal bacteria promote host reproduction by modulating metabolism and nutrition, but the molecular mechanisms by which microbes regulate reproduction remain unclear. Here, we show that gut commensal bacteria promote host reproduction by providing amino-acid methionine, which controls the ...

MetabolomicsSystemic Inflammation Induces Cholestasis via Upregulating a Short Variant of FTO to Remove the m6A Methylation in the 3’-UTR of Cyp7b1 mRNAs in liver
The cholestasis frequently occurs in patients with inflammatory processes. However, the mechanisms of inflammation in inducing cholestasis are still unclear. Here, by using lipopolysaccharide (LPS)-induced cholestasis mouse models, we found that most genes encoding enzymes responsible for bile acid ...

ProteomicsIgG M-protein quantification by PRM in blood of multiple myeloma patient
The amino acid sequence of the M-protein for multiple myeloma is unique compared to the polyclonal antibodies in patients’ blood. This uniqueness is exploited to develop an ultra-sensitive M-protein detection method utilizing mass spectrometry (MS). The method involves the de novo amino acid sequenc...

MetabolomicsSmall intestinal microbial dysbiosis underlies symptoms associated with functional gastrointestinal disorders
Small intestinal bacterial overgrowth (SIBO) has been implicated in symptoms associated with functional gastrointestinal disorders (FGIDs), though mechanisms remain poorly defined and treatment involves non-specific antibiotics. Here we show that SIBO based on duodenal aspirate culture reflects an o...

TranscriptomicsMicroRNAs regulate DC maturation via M-CSFR
We identify a panel of microRNAs that are differentially expressed during both spontaneous and LPS-induced DC maturation and show the M-CSF receptor (M-CSFR) as a key target for microRNA-mediated regulation. MicroRNA-22, -34a and -155 are up-regulated in mature GM-CSF-generated DC and mediate M-CSFR...

MetabolomicsGut Microbiota Dysbiosis and Hypercholesterolemia Are Associated with Bone Metastasis in Non-Small Cell Lung Cancer
We collected baseline fecal samples from 85 patients with newly diagnosed lung cancer, 51 patients with bone metastasis (M group), and 34 patients without bone metastasis (N group). We conducted metagenomic and metabolomic sequencing to compare the differences in gut microbiota and metabolites betwe...

MetabolomicsSmall Polar Hits against S. aureus: Screening, Initial Hit Optimization, and Metabolomic Studies
The global prevalence of antibacterial resistance requires new antibacterial drugs with novel chemical scaffolds and modes of action. It is also vital to design compounds with optimal physicochemical properties to permeate the bacterial cell envelope. We described an approach of combining and integr...

ProteomicsLabel-free shotgun proteomics of M. hyopneumoniae and M. feriruminatoris
Mycoplasmas are wall-less parasitic bacteria possessing extremely small genomes. Despite this, growth rates differ among mycoplasma species with doubling times ranging from only 0.5h to 16h. Here, we analyzed the whole proteomes of M. hyopneumoniae and M. feriruminatoris and performed a comparative ...
