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...

TranscriptomicsSkeletal muscle and insulin regulated genes
Insulin action in target tissues involved precise regulation of gene expression. To define the set of insulin-regulated genes in human skeletal muscle, we analyzed the global changes in mRNA levels during a 3-h hyperinsulinemic euglycemic clamp in vastus lateralis muscle of six healthy subjects. Usi...

TranscriptomicsHuman Insulin Resistance and Thiazolidinedione-Mediated Insulin Sensitization
Cellular and tissue defects associated with insulin resistance are coincident with transcriptional abnormalities and are improved after insulin sensitization with thiazolidinedione (TZD) PPAR? ligands. We transcriptionally profiled 364 biopsies gathered from 72 human subjects harvested before and af...

TranscriptomicsInsulin resistance induced by physical inactivity is associated with multiple transcriptional changes in skeletal muscle in young men
Rationale: Physical inactivity is a risk factor for insulin resistance. We examined the effect of nine days of bed rest on basal and insulin stimulated expression of genes potentially involved in insulin action by applying hypothesis-generating microarray in parallel with candidate gene real-time PC...

TranscriptomicsTranscription profiling of preadipocytes of wild type and IRS-1,IRS-2, IRS-3, IRS-4 knock out mice to reveal role of insulin receptor substrates and necdin
Insulin and IGF-1 promote adipocyte differentiation via complex and overlapping signalling networks. Here we used microarray analysis of brown preadipocytes derived from wild-type and insulin receptor substrate (IRS) knockout (KO) animals, which exhibited progressively impaired differentiation, to ...

TranscriptomicsAdipose Rab10 Knockout Causes Insulin Resistance through Impaired Glucose Uptake
Insulin action in adipocytes affects whole-body insulin sensitivity. Studies of adipose-specific Glut4 knockout mice have established that adipose Glut4 contributes to the control of systemic glucose homeostasis. Presumably, this reflects a role for Glut4-mediated glucose transport in the regulation...

TranscriptomicsFKBP5 expression in human adipose tissue increases following dexamethasone exposure and is associated with insulin resistance.
Glucocorticoid excess is linked to central obesity, adipose tissue insulin resistance and type 2 diabetes mellitus. The aim of our study was to investigate the effects of dexamethasone on gene expression in human subcutaneous and omental adipose tissue, in order to identify potential novel mechanism...

TranscriptomicsEffect of insulin infusion on human skeletal muscle
To identify insulin responsive genes in humans, in the first protocol, skeletal muscle biopsies from six non-diabetic subjects were obtained before and after a two-hour of hyperinsulinaemic (infusion rate 40 mU/m2/min) euglycemic clamp. A variable infusion of glucose (180 g/l) enriched with tritiate...

TranscriptomicsTranscription profiling of human mesenchymal stem cell derived stromal and adipocyte cells treated with insulin.
There are an estimated 21million diabetics in the United States and 150 million diabetics worldwide. The World Health Organization anticipates that these numbers will double in the next 20 years. Metabolic syndrome is a well recognized set of symptoms that increases a patient’s risk of developing d...
