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...

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...

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...

MetabolomicsMechanistic insights revealed by lipid profiling in monogenic insulin resistance syndromes (Mouse 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...

GenomicsComprehensive analysis of different in vitro insulin resistance models
Diet-induced obesity (DIO) predisposes individuals to insulin resistance, and adipose tissue has a major role in the disease. Insulin resistance can be induced in cultured adipocytes by a variety of treatments, but what aspects of the in vivo responses are captured by these models remains unknown. W...

MetabolomicsInsulin Resistance-Associated Bifidobacterium longum Ameliorates Prediabetes via the 6-ketoLCA/TGR5/GLP-1 axis

Background Prediabetes, a global health concern characterized by insulin resistance (IR) and closely linked to obesity, was investigated in this study to identify key gut microbiota characteristics. The development of insulin resistance is associated with gut microbiota. Therefore, identifying ke...

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 (...

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 ...

GenomicsCharacterizing the profiles of histone markers in mouse adipocytes during insulin resistance
Insulin resistance is a sine qua non of Type 2 diabetes (T2D) and a frequent complication of multiple clinical conditions, including obesity, aging, and steroid use, among others. How such a panoply of insults can result in a common phenotype is incompletely understood. Furthermore, very little is k...
