MetabolomicsA Calorie-restricted Dietary Intervention Alleviates Obesity-induced MASLD via the Microbiota-5-hydroxyindoleacetic acid–Pregnane X Receptor Axis

Metabolic dysfunction-associated steatotic liver disease (MASLD) represents the most common chronic liver disease worldwide. Caloric restriction (CR) is a major dietary intervention known to reshape the gut microbiota; however, the implications of these microbial changes for MASLD pathophysiology...

MetabolomicsMetabolic Effects of a Chronic Dietary Exposure to a Low-Dose Pesticide Cocktail in Mice: Sexual Dimorphism and Role of the Constitutive Androstane Receptor (Untargeted urine, plasma and liver NMR assay)
BACKGROUND: Epidemiological evidence suggests a link between pesticide exposure and the development of metabolic diseases. However, most experimental studies have evaluated the metabolic effects of pesticides using individual molecules, often at non-relevant doses or in combination with other r...

MetabolomicsThe dynamic clustering of insulin receptor underlies its signaling and is disrupted in insulin resistance
Insulin receptor (IR) signaling is central to normal metabolic control and is dysregulated in metabolic diseases such as type 2 diabetes. We report here that IR is incorporated into dynamic clusters at the plasma membrane, in the cytoplasm and in the nucleus of human hepatocytes and adipocytes. Insu...

MetabolomicsDeletion of glycerol channel aquaporin-9 (Aqp9) impairs long-term blood glucose control in C57BL/6 leptin receptor-deficient (db/db) obese mice
Deletion of the glycerol channel aquaporin-9 (Aqp9) reduces postprandial blood glucose levels in leptin receptor deficient (db/db) obese mice on a C57BL/6×C57BLKS mixed genetic background. Furthermore, shRNA mediated reduction of Aqp9 expression reduces liver triacylglycerol (TAG) accumulation in a ...

MetabolomicsA metabolite-augmented FIB-4 machine learning panel achieves superior liver fibrosis staging in chronic liver disease

Accurate, non-invasive liver fibrosis detection is essential for chronic liver disease management, particularly with rising metabolic dysfunction-associated liver disease (MASLD) and chronic hepatitis B (CHB). While the Fibrosis-4 (FIB-4) index is widely used, its performance for advanced fibrosi...

MetabolomicsMetabolic Effects of a Chronic Dietary Exposure to a Low-Dose Pesticide Cocktail in Mice: Sexual Dimorphism and Role of the Constitutive Androstane Receptor (Untargeted urine UPLC-MS assay)
BACKGROUND: Epidemiological evidence suggests a link between pesticide exposure and the development of metabolic diseases. However, most experimental studies have evaluated the metabolic effects of pesticides using individual molecules, often at non relevant doses or in combination with other r...

MetabolomicsGenome-scale study reveals reduced metabolic adaptability in patients with non-alcoholic fatty liver disease
Non-alcoholic fatty liver disease (NAFLD) is a major risk factor leading to chronic liver disease and type 2 diabetes. Here we chart liver metabolic activity and functionality in NAFLD by integrating global transcriptomic data, from human liver biopsies, and metabolic flux data, measured across the ...

MetabolomicsThe Effects of Combined Aerobic and Resistance Exercise on Liver Metabolomics in Mice Fed a High-Fat Diet

Background and Objectives: Obesity is often accompanied by hepatic metabolic disorders and chronic low-grade inflammation. While combined aerobic and resistance exercise is considered an intervention to improve body composition, its systematic regulatory effects on the hepatic metabolic profile r...

MetabolomicsA multi-omics approach to study peroxisome proliferator-activated receptor mediated regulation of lipid metabolism in Atlantic cod (Gadus morhua)
Lipid metabolism is essential in maintaining energy homeostasis in multicellular organisms. In vertebrates, a group of nuclear receptor transcription factors named peroxisome proliferator-activated receptors (PPARs, NR1C) regulate the expression of many genes involved in these processes. We have rec...

MetabolomicsMetabolic profiling of ob/ob mouse fatty liver using HR-MAS 1H-NMR combined with gene expression analysis reveals alterations in betaine metabolism and the transsulfuration pathway
Metabolic perturbations resulting from excessive hepatic fat accumulation are poorly understood. Thus, in this study, leptin-deficient ob/ob mice, a mouse model of fatty liver disease, were used to investigate metabolic alterations in more detail. Metabolites were quantified in intact liver tissues ...
