MetabolomicsA data integration multi-omics approach to study calorie restriction-induced changes in insulin sensitivity
The mechanisms responsible for weight loss-induced improvement in insulin sensitivity are partially understood. Greater insight can now be achieved through deep phenotyping and data integration. Here, we used an integrative approach to investigate associations between changes in insulin sensitivity ...

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...

MetabolomicsTiming of unsaturated fat intake improves insulin sensitivity through gut microbiota-dependent regulation of bile acid metabolism: a randomized controlled trial

The timing of dietary fat intake influences metabolic health. However, the impact of the timing of unsaturated fat (USFA) intake on glycemic control has yet to be explored. This 12-week, double-blind, randomized, controlled, 2 x 2 factorial-designed feeding trial investigated the effects of timin...

MetabolomicsGlobal Analyses of Selective Insulin Resistance in Hepatocytes due to Palmitate Lipotoxicity
Obesity is tightly linked to hepatic steatosis and insulin resistance. One feature of this association is the paradox of selective insulin resistance: insulin fails to suppress hepatic gluconeogenesis but activates lipid synthesis in the liver. How lipid accumulation interferes selectively with some...

MetabolomicsIntegration of whole-body [18F]FDG PET/MRI with non-targeted metabolomics can provide new insights on tissue-specific insulin resistance in type 2 diabetes
Alteration of various metabolites has been linked to type 2 diabetes (T2D) and insulin resistance. However, identifying significant associations between metabolites and tissue-specific phenotypes requires a multi-omics approach. In a cohort of 42 subjects with different levels of glucose tolerance (...

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 ...

MetabolomicsMechanistic insights revealed by lipid profiling in monogenic insulin resistance syndromes (Human data)
Evidence from several recent metabolomic studies suggests that increased concentrations of triacylglycerols (TAGs) with shorter (14-16 carbon atoms), saturated fatty acids are associated with insulin resistance and the risk of type 2 diabetes. Although causality cannot be inferred from association s...

TranscriptomicsPolyunsaturated fatty acids acutely affect triacylglycerol-derived skeletal muscle fatty acid uptake and increases postprandial insulin sensitivity
Dietary fat quality may influence skeletal muscle lipid handling and fat accumulation, thereby modulating insulin sensitivity. Objective: To examine acute effects of meals with various fatty acid (FA) compositions on skeletal muscle FA handling and postprandial insulin sensitivity in obese insulin r...
