MetabolomicsDietary carbohydrate and protein levels affect the growth performance of juvenile peanut worm (Sipunculus nudus): an LC–MS-based metabolomics study
The peanut worm (Sipunculus nudus) is an economically important fishery resource in China. To determine how dietary carbohydrate and protein levels affects the growth performance of juvenile S. nudus and identify the mechanisms underlying observedpatterns, five isoenergetic and isolipidic diets with...

MetabolomicsA targeted MRM-based lipidomic dataset of Tenebrio molitor larvae fed diets with different protein levels
Tenebrio molitor is increasingly used as a sustainable source of nutrients for food and feed production, yet their lipid metabolic responses to dietary protein remain poorly characterized at the molecular species level. Here, we report a targeted UPLC–MS/MS lipidomics dataset of Tenebrio molitor lar...

MetabolomicsA low protein diet drives short and long-term improvements in metabolic health in a mouse model of sleeve gastrectomy

Despite the largely beneficial impact of bariatric surgery on obesity and metabolic disease, many patients continue to suffer from obesity after surgery and weight recurrence is common. The success of bariatric surgery may be impacted by diet. While bariatric surgery guidelines recommend a high-p...

MetabolomicsMetabolic effects of dietary glycerol supplementation in muscle and liver of European seabass and rainbow trout by 1H NMR metabolomics
The sustainable growth of fish aquaculture will require the procurement of non-marine feed sources. Glycerol is a potential feed supplement whose metabolism may spare the catabolism of dietary amino acids, thereby extending the use of the feed protein to other physiological functions such as growth....

MetabolomicsDietary restriction of cysteine and methionine sensitizes gliomas to ferroptosis and induces alterations in energetic metabolism

Ferroptosis is mediated by lipid peroxidation of phospholipids containing polyunsaturated fatty acyl moieties. Glutathione, the key cellular antioxidant capable of inhibiting lipid peroxidation via the activity of the enzyme glutathione peroxidase 4 (GPX-4), is generated directly from the sulfur-...

MetabolomicsMicrobiome Metabolism of Dietary Phytochemicals Controls the Anticancer Activity of PI3K Inhibitors
Phosphatidylinositol 3-kinase (PI3K) signaling is both the effector pathway of insulin and among the most frequently activated pathways in human cancer. In murine cancer models, the efficacy of PI3K inhibitors is dramatically enhanced by a ketogenic diet, with a proposed mechanism involving dietary ...

MetabolomicsThe Effect of Dietary BIoactives on Gut Microbiome DivErsity (DIME) - A pilot study (Untargeted metabolomics)

The gut microbiome refers to the complex community of microorganisms (bacteria, fungi, archaea and viruses) present within our gut. The composition and complexity of gut microbiota communities are crucial for maintaining human health. Humans depend on the gut microbiota to undertake essential met...

MetabolomicsUrban living in healthy Tanzanians is associated with an inflammatory status driven by dietary and metabolic changes
Sub-Saharan Africa currently experiences an unprecedented wave of urbanization, which has important consequences for health and disease patterns. This study aimed to investigate and integrate the immune and metabolic consequences of rural or urban lifestyles and the role of nutritional changes assoc...

MetabolomicsLow-Protein Diet Enhances Anti-Tumor Immunity in Pancreatic Cancer through Microbiota-Derived Uridine Diphosphate-Galactose
Low-protein diets (LPD) have been linked to improved metabolic health, but their role in pancreatic ductal adenocarcinoma (PDAC) immunotherapy remains unclear. Here we show that an LPD suppresses PDAC progression in male mice by remodeling the gut microbiota and activating anti-tumor immunity. LPD p...
