(Submitter supplied) The current study aimed to address the hypothesis that programmed expression of key miRNAs in skeletal muscle mediates the development of insulin resistance, and consequently long-term health. We thus examined microRNA signatures in skeletal muscle of programmed insulin resistant rats offspring from high fat-fed dams vs control offspring from chow fed dams.

(Submitter supplied) MicroRNAs (miRNAs) are noncoding RNAs representing an important class of gene expression modulators. Extracellular circulating miRNAs are both candidate biomarkers for disease pathogenesis and mediators of cell-to-cell communication. We examined the miRNA expression profile of total serum and serum derived exosome-enriched extracellular vesicles in people with normal glucose tolerance or type 2 diabetes. more...

(Submitter supplied) Maternal obesity can program metabolic syndrome in offspring but the mechanisms are not well characterized. Moreover, the consequences of maternal overnutrition in the absence of frank obesity remain poorly understood. This study aimed to determine the effects of maternal consumption of a high fat-sucrose diet on the skeletal muscle metabolic and transcriptional profiles of adult offspring. Female Sprague Dawley rats were fed either a diet rich in saturated fat and sucrose (HFD, 23.5% fat, 20% sucrose wt/wt) or a standard chow diet (NFD, 7% fat, 10% sucrose w/w) for the 3 weeks prior to mating and throughout pregnancy and lactation. more...

(Submitter supplied) The Igf2 mRNA binding protein2/Imp2 was selectively deleted from adult mouse muscle; two phenotypes were observed: modestly decreased accrual of skeletal muscle mass after weaning and reduced wheel running activity but normal forced treadmill performance. Reduced voluntary activity occurs when fed a high fat diet but is normalized when consuming standard chow. The reduced muscle mass is due to diminished autocrine Igf2 production, reduced Akt1 activation, disinhibition of Gsk3α and reduced protein synthesis, without altered mTOR complex1 activity. more...

(Submitter supplied) Type 2 diabetes mellitus (DM) is characterized by insulin resistance and pancreatic beta-cell dysfunction. In high-risk subjects, the earliest detectable abnormality is insulin resistance in skeletal muscle. Impaired insulin-mediated signaling, gene expression, and glycogen synthesis, and accumulation of intramyocellular triglycerides have all been linked with insulin resistance, but no specific defect responsible for insulin resistance and DM has been identified in humans. more...

(Submitter supplied) Dysregulation in expression of microRNAs (miRNAs) in various tissues has been linked to a wide spectrum of diseases, including Type 2 Diabetes mellitus (T2D). In this study, we compared the expression profiles of miRNAs in blood samples from Impaired Fasting Glucose (IFG) and T2D male patients with tissues from T2D rat models. Healthy adult males with no past history of T2D (n=158) and with desirable cholesterol and blood pressure profiles were enrolled in this study. more...

(Submitter supplied) The contribution of altered posttranscriptional gene silencing (PTGS) to the development of insulin resistance and type 2 diabetes mellitus so far remains elusive. We have described that expression of microRNAs (miR)-143 and -145 is dysregulated in genetic and dietary mouse models of obesity. Induced transgenic overexpression of miR-143, but not miR-145, causes insulin resistance and impaired insulin-stimulated AKT activation. more...

(Submitter supplied) Impaired skeletal muscle function is a central feature in the pathophysiology of type 2 diabetes (T2DM). The disease phenotype could be due to immature muscle cell development, which in turn may occur as the result of disturbed microRNA-mediated regulation of muscle differentiation in T2DM. To address this hypothesis, we assessed global miRNA expression during in vitro differentiation of muscle stem cells derived from T2DM patients and healthy controls. more...

(Submitter supplied) Objective: Decreased muscle mass is a major contributor to age-related morbidity, and strategies to improve muscle regeneration during ageing are urgently needed. Our aim was to identify the subset of relevant microRNAs (miRNAs) that partake in critical aspects of muscle cell differentiation, irrespective of computational predictions, genomic clustering or differential expression of the miRNAs. Methods: miRNA biogenesis was deleted in primary myoblasts using a tamoxifen-inducible CreLox system and combined with an add-back miRNA library screen. more...
