(Submitter supplied) Obesity and type 2 diabetes (T2D) are metabolic disorders influenced by lifestyle and genetic factors, and characterized by insulin resistance in skeletal muscle, a prominent site of glucose disposal. Numerous genetic variants have been associated with obesity and T2D, of which the majority is located in non-coding DNA regions. This suggest that most variants mediate their effect by altering the activity of gene-regulatory elements, including enhancers. more...

(Submitter supplied) To identify mediators of obesity-linked reductions in PGC-1, we tested the effects of cellular nutrients in C2C12 myotubes. While overnight exposure to high insulin, glucose, glucosamine, or amino acids had no effect, saturated fatty acids (FA) potently reduced PGC-1a and b mRNA expression. Keywords: Nutrient Effect

Analysis of myoblasts treated with the saturated fatty acid palmitate. Muscle expression of PPAR coactivator 1 (PGC-1) is reduced in models of obesity. Palmitate decreases the expression of PGC-1. Results provide insight into the molecular basis of the link between overnutrition, obesity, and PGC-1.

(Submitter supplied) We screened intronic microRNAs dysregulated in liver of obese mouse models to identify previously uncharacterized coding host genes that may contribute to the pathogenesis of obesity-associated insulin resistance and type 2 diabetes mellitus. Our approach identified the expression of Ectodysplasin A (Eda), the causal gene of X-linked hypohidrotic ectodermal dysplasia (XLHED; MIM 305100) was strongly increased in liver of obese mouse models both in rodents and humans.Eda expression in murine liver is controlled via PPARγ activation, increases in circulation and promotes JNK activation and inhibitory serine phosphorylation of IRS1 in skeletal muscle. more...

(Submitter supplied) Objective: Homozygous loss-of-function mutations in the gene coding for the homeobox transcription factor (TF) PDX1 leads to pancreatic agenesis, whereas heterozygous mutations can cause Maturity-Onset Diabetes of the Young 4 (MODY4). Although the function of Pdx1 is well studied in pre-clinical models during insulin-producing β-cell development and homeostasis, it remains elusive how this TF controls human pancreas development by regulating a downstream transcriptional program. more...

(Submitter supplied) Omega-3 and omega-6 polyunsaturated fatty acids (PUFA) have important signalling roles in the body. The goal of this study was to investigate the impact of linoleic acid (LA, omega-6) and alpha-linolenic (ALA, omega-3) on global skeletal muscle gene expression. We were also interested to study the impact of these fatty acids on myokine expression. To differentiate the roles of essential dietary PUFA on skeletal muscle function, we fed male rats a control diet (AIN-93G) or diets containing 10% safflower oil or flaxseed oil. more...

(Submitter supplied) Myostatin (GDF8) is a member of the TGF-beta family of proteins which is predominantly expressed in skeletal muscle and acts as a negative regulator of muscle mass. Inhibition of myostatin leads to muscle hypertrophy and has been shown to mitigate insulin resistance in mouse models of type 2 diabetes, although the mechanisms underlying this effect are unclear. We found that myostatin inhibition by AAV-mediated overexpression of the myostatin propeptide improves skeletal muscle insulin sensitivity in mice made insulin-resistant by high fat diet feeding. more...

(Submitter supplied) Skeletal muscle is one of the primary tissues involved in the development of type 2 diabetes (T2D). Obesity is tightly associated with T2D, making it challenging to isolate specific effects attributed to the disease alone. By using an in vitro myocyte model system we were able to isolate the inherent properties retained in myocytes originating from donor muscle precursor cells, without being confounded by varying extracellular factors present in the in vivo environment of the donor. more...

(Submitter supplied) Skeletal myocytes are metabolically active and susceptible to insulin resistance, thus implicated in type 2 diabetes (T2D). This complex disease involves systemic metabolic changes and their elucidation at the systems level requires genome-wide data and biological networks. Genome-scale metabolic models (GEMs) provide a network-context to integrate high-throughput data. We generated myocyte-specific RNA-seq data and investigated their correlation with proteome data. more...
