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 (...

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...

TranscriptomicsTranscription profiling of soleus muscle from lean and obese Zucker rats following exercise training
Endurance exercise training has been shown to decrease whole-body and skeletal muscle insulin resistance and increase glucose tolerance in conditions of both pre-diabetes and overt type 2 diabetes. However, the adaptive responses in skeletal muscle at the molecular and genetic level for these benef...

TranscriptomicsThe G Protein-coupled Receptor P2Y14 Influences Insulin Release and Smooth Muscle Function in Mice
UDP-sugars were identified as extracellular signaling molecules, assigning a new function to these compounds in addition to their well defined role in intracellular substrate metabolism and storage. Previously regarded as an orphan receptor, the G protein-coupled receptor (GPCR) P2Y14 (GPR105) was f...

TranscriptomicsTranscription profiling of mouse liver response to a glucose challenge in healthy and insulin resistant C57BL/6J mice
The goal of this experiment is to compare the transcriptional response to a metabolic stressor (glucose bolus) between healthy and insulin resistant mouse liver. Mice with an isogenic background (C57BL/6J mice) were fed diets for 12 weeks containing either 10 or 45% fat by energy (mainly palm oil) a...

TranscriptomicsTranscription profiling of mouse small intestine in the development of dietary fat-induced obesity and insulin resistance in C57BL/6J strain.
Obesity and insulin resistance are two major risk factors underlying the metabolic syndrome. To gain more insight in the role of the small intestine in the etiology of these metabolic disorders, a microarray study was performed on small intestines (SI) of C57BL/6J mice that were fed a high fat diet ...

TranscriptomicsNutritional Strategy to Prevent Fatty Liver and Insulin Resistance Independent of Obesity by Reducing GIP Responses
High intakes of carbohydrates, particularly sucrose, in Western societies are associated with the development of non-alcoholic fatty liver (NAFL) and diabetes mellitus. It is unclear whether this is related to the carbohydrate quantity or the hormonal responses, particularly Glucose-dependent Insuli...

TranscriptomicsBenefits of a 6 week supplementation of sebacic acid on a mouse model of type 2 diabetes (db/db mice)
This study aimed at investigating the impact of chronic ingestion of sebacic acid (SA), a 10 carbons medium-chain dicarboxylic acid, on glycemic control in a mouse model of type 2 diabetes (db/db mice). Three groups of 15 mice were fed for 6 weeks either a chow diet (Ctrl), or a chow diet supplement...

TranscriptomicsSupplementary dietary calcium stimulates faecal fat and bile acid excretion, but does not protect against obesity and insulin resistance in C57BL/6J mice
There is increased interest in the potential protective role of dietary Ca in the development of metabolic disorders related to the metabolic syndrome. Ca-induced intestinal precipitation of fatty acids and bile acids as well as systemic metabolic effects of Ca on adipose tissue is proposed to play ...
