The signalling architecture of skeletal muscle insulin resistance

ABSTRACT: Insulin resistance, the defective regulation of glucose metabolism by insulin, increases the risk of type 2 diabetes and cardiovascular disease. It is not yet known how insulin resistance remodels signalling networks in human tissues. Here, we define the signalling architecture of insulin resistance in skeletal muscle. We measured phenotypes and phosphoproteomes of insulin resistant and insulin sensitive subjects as they responded to exercise and an insulin infusion, quantifying more than 26,000 phosphosites in 114 skeletal muscle biopsies. Incorporating a temporal component to personalised phosphoproteomics identified signalling linked with the range of insulin sensitivity across the participants.

Personalised phosphoproteomics extracts functional signalling

Project description:Protein phosphorylation dynamically integrates environmental and cellular information to control virtually all biological processes. Identifying functional phosphorylation amongst the thousands of phosphosites regulated by a perturbation at a global scale is a major challenge. Here, we introduce personalised phosphoproteomics, an experimental and computational framework to link signalling with biological function by exploiting human phenotypic variance. This is achieved by measuring individual subject phosphoproteome responses to interventions with corresponding phenotypes measured in parallel. We employed this method to investigate how exercise potentiates insulin sensitivity in human skeletal muscle. Our approach extracted signalling highly enriched in known functional sites, as well as many previously unknown sites on proteins intimately involved in glucose metabolism. This included a new co-operative relationship between mTOR and AMPK, for which we found a role in metabolic regulation. These results establish personalised phosphoproteomics as a general approach to investigate the signal transduction underlying complex biology.

The genetic and dietary landscape of the muscle insulin signalling network

Project description:Using mass spectrometry-based phosphoproteomics, we quantified 23,126 phosphosites in the skeletal muscle of five genetically distinct inbred mouse strains exposed to two controlled dietary environments, with and without acute insulin treatment. Almost half of the insulin-regulated phosphoproteome was altered by genetic background independently of diet, and high-fat high-sugar feeding also affected insulin signalling in a strain-dependent manner. Our data illuminated signalling network organisation principles, including the uncoupling of phosphosites targeted by the same kinase. Associating diverse signalling responses with insulin-stimulated glucose uptake uncovered regulators of muscle insulin responsiveness, including the regulatory phosphosite S469 on Pfkfb2, a key glycolytic enzyme.

Effect of insulin infusion on human skeletal muscle

Project description: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 tritiated glucose (100 μCi/500 ml) maintained euglycemia during insulin infusion, with monitoring of plasma glucose concentration every 5 to 10 min during the basal and clamp periods using an automated glucose oxidation method (Glucose Analyzer 2, Beckman Instruments, Fullerton, CA). In the second protocol, skeletal muscle biopsies from six non-diabetic subjects were obtained before and after a 3-hour hyperinsulinemic (infusion rate 40 mU/m2/min) euglycemic clamp in order to increase the effects of insulin on gene expression. A variable infusion of glucose (180 g/l) was used to maintain euglycemia during insulin infusion with monitoring of plasma glucose concentration every 5 to 10 min using an automated glucose oxidation method (Glucose Analyzer 2, Beckman Instruments, Fullerton, CA). Keywords: dose response The muscle biopsies were obtained from the vastus lateralis muscle under local anesthesia before and after hyperinsulinaemic (infusion rate 40 mU/m2/min) euglycemic clamp

Expression data from human skeletal muscle

Project description:The accumulation of intramyocellular lipid (IMCL) is recognized as an important determinant of insulin resistance, and is increased by a high-fat diet (HFD). However, the effects of HFD on IMCL and insulin sensitivity are highly variable. We used microarrays to detail to identify the genes in skeletal muscle that are related to inter-individual variation of the effects with HFD on the accumulation of intramyocellular lipid and insulin sensitivity. In order to identify the gene expression profile related with inter-individual variation of the effects with high fat diet on the accumulation of intramyocellular lipid and insulin sensitivity, we classified subjects who showed a large increase in intramyocellular lipid and a large decrease in glucose infusion rate by high fat diet as the high-responder (HR), and the subjects who showed a small increase in intramyocellular lipid and a small decrease in glucose infusion rate were classified as the low-responder (LR). In 5 subjects in each group, skeletal muscle sample selected at before (pre) and after (post) 3days high fat diet for RNA extraction and hybridization on Affymetrix microarrays.

Enhanced metabolic resilience and exercise adaptation of skeletal muscle in males by Esr1-induced remodeling of mitochondrial cristae-nucleoid architecture

Project description:Reduced estrogen action is associated with obesity and insulin resistance. However, the cell and tissue-specific actions of estradiol in maintaining metabolic health remain inadequately understood especially in men. We observed that skeletal muscle ESR1/Esr1 (encodes estrogen receptor a), including expression of specific ESR1 variants is positively correlated with insulin sensitivity and metabolic health in humans and mice. Because skeletal muscle is a primary tissue involved in oxidative metabolism and insulin sensitivity, we generated muscle-selective Esr1 loss- and gain of-expression mouse models. We determined that Esr1 links mitochondrial DNA replication and cristae-nucleoid architecture with metabolic function and insulin action in skeletal muscle of male mice. Overexpression of human ERα in muscle protected male mice from diet-induced disruption of metabolic health and enhanced mitochondrial adaptation to exercise training intervention. Our findings indicate that muscle expression of Esr1 is critical for the maintenance of mitochondrial function and metabolic health in males, and that tissue-selective activation of ERα can be leveraged to combat metabolic-related diseases in both sexes.

Increased SRF Transcriptional Activity is a Novel Signature of Insulin Resistance in Humans and Mice

Project description:Insulin resistance in skeletal muscle is a key phenotype associated with type 2 diabetes (T2D) and is even present in offspring of diabetic parents. However, molecular mediators of insulin resistance remain unclear. We find that the top-ranking gene set in expression analysis of muscle from humans with T2D and normoglycemic insulin resistant subjects with parental family history (FH+) of T2D is increased expression of actin cytoskeleton genes regulated by serum response factor (SRF) and its coactivator MKL1. Furthermore, the SRF activator STARS is upregulated in FH+ and T2D and inversely correlated with insulin sensitivity. These patterns are recapitulated in insulin resistant mice, and linked to alterations in two other regulators of this pathway: reduced G-actin and increased nuclear localization of MKL1. Both genetic and pharmacologic manipulation of STARS/MKL1/SRF pathway significantly alter insulin action: 1) Overexpression of MKL1 or reduction in G-actin decreased insulin-stimulated Akt phosphorylation; 2) reduced STARS expression increased insulin signalling and glucose uptake, and 3) SRF inhibition by CCG-1423 reduced nuclear MKL1, improved glucose uptake, and improved glucose tolerance in insulin resistant mice in vivo. Thus, SRF pathway alterations are a signature of insulin resistance which may also contribute to T2D pathogenesis and be a novel therapeutic target. Skeletal muscle samples were obtained from 10 subjects with type 2 diabetes, 25 subjects with a family history of type 2 diabetes (one or both parents), and 15 subjects with no family history of type 2 diabetes. In this analysis RNA was isolated for cRNA preparation and hybridized to Affymetrix Human Genome U133 Plus 2.0 microarrays.

Phosphoproteomics reveals rewiring of the insulin signaling network and multi-nodal defects in insulin resistance

Project description:Here we employed phosphoproteomics to delineate insulin signal transduction in adipocyte cells and adipose tissue. Across a range of insults triggering insulin resistance, we observed marked rewiring of the insulin signaling network. This included both attenuated insulin-responsive phosphorylation, and the emergence of phosphorylation uniquely insulin-regulated in insulin resistance. Identifying dysregulated phosphosites common to multiple insults revealed subnetworks containing novel regulators of insulin action, such as MARK2/3, and causal drivers of insulin resistance. The presence of several GSK3 substrates among these phosphosites led us to establish a pipeline for identifying context-specific kinase substrates. This revealed widespread dysregulation of GSK3 signaling. Pharmacological inhibition of GSK3 partially reversed insulin resistance in cells and tissue explants. These data highlight that insulin resistance is multi-nodal signaling defect that includes dysregulated GSK3 activity.
