Type 2 diabetes: myotube

Analysis of myotube cell lines established from type 2 diabetes (T2D) subjects. Insulin resistance and reduced mitochondrial biogenesis coexist early in T2D pathogenesis independent of hyperglycemia and obesity. Results provide insight into the effect of T2D on developing skeletal muscle cells.

Transcription profiling of myotubes from patients with type 2 diabetes

(Submitter supplied) Microarray-based studies of skeletal muscle from patients with type 2 diabetes and high-risk individuals have demonstrated that insulin resistance and reduced mitochondrial biogenesis co-exist early in the pathogenesis of type 2 diabetes independent of hyperglycaemia and obesity. It is unknown whether reduced mitochondrial biogenesis or other transcriptional alterations co-exist with impaired insulin-responsiveness in primary human muscle cells from patients with type 2 diabetes. more...

Reduced expression of mitochondrial oxidative metabolism genes in skeletal muscle of women with PCOS

(Submitter supplied) Recently, abnormalities in mitochondrial oxidative phosphorylation (OXPHOS) have been implicated in the pathogenesis of skeletal muscle insulin resistance in type 2 diabetes. In the present study, we hypothesized that decreased expression of OXPHOS genes could be of similar importance for insulin resistance in the polycystic ovary syndrome (PCOS). Using the HG-U133 Plus 2.0 expression array from Affymetrix, we analyzed gene expression in skeletal muscle from obese women with PCOS (n=16) and age- and body mass index-matched control women (n=13) metabolically characterized by euglycemic-hyperinsulinemic clamp and indirect calorimetry. more...

Human skeletal muscle - type 2 diabetes and family history positive individuals - Mexican American

(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...

Relationship between insulin sensitivity and gene expression in human skeletal muscle

(Submitter supplied) The aim of this study was therefore to investigate molecular mechanisms associated with insulin sensitivity in skeletal muscle by relating global skeletal muscle gene expression with a surrogate measure of insulin sensitivity, i.e. homeostatic model assessment of insulin resistance (HOMA-IR). To identify genes with skeletal muscle expression related to insulin sensitivity, we obtained muscle biopsies from 38 non-diabetic participants in study A. more...

Relationship between insulin sensitivity and gene expression in human skeletal muscle (Study B)

(Submitter supplied) We studied 9 healthy young non-diabetic men without any family history of diabetes. The mean age and body mass index (BMI) were 25.33 ± 0.33 years and 24.57 ± 0.62 kg/m2, respectively, and the mean 1/ homeostatic model assessment of insulin resistance (HOMA-IR) was 1.17 ± 0.12. We included baseline gene expression profile data (i.e. only before bed rest)

Insulin resistance induced by physical inactivity is associated with multiple transcriptional changes in skeletal muscle in young men

(Submitter supplied) 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 PCR approaches in 20 healthy, young men. Furthermore, we investigated whether bed rest affected DNA methylation in the promoter region of the peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PPARGC1A) gene. more...

Progressive loss of PGC-1alpha expression in aging muscle potentiates glucose intolerance and systemic inflammation

(Submitter supplied) Decreased mitochondrial mass and function in muscle of diabetic patients is associated with low PGC-1alpha, a transcriptional coactivator of the mitochondrial gene program. To investigate whether reduced PGC-1alpha and oxidative capacity in muscle directly contributes to age-related glucose intolerance, we compared the genetic signatures and metabolic profiles of aging mice lacking muscle PGC-1alpha. more...

Analysis of PGC-1alpha overexpression effects on the whole transcriptome in cultured skeletal muscle cells

(Submitter supplied) The transcriptional coactivator peroxisome proliferator-activated receptor-gamma coactivator 1 alpha (PGC-1α) is a chief activator of the mitochondrial and metatolic program in skeletal muscle (skm) and prevents atrophy. Here we tested whether PGC-1α overexpression could restructure the transcriptome and metabolism of cultured human skeletal myotubes, which display an athropic phenotype. An oligonucleotide microarray analysis was used to reveal PGC-1α effects on the whole transcriptome, and the possible impact on fuel metabolism reprogramming was examined. more...

Gene expression profiling in skeletal muscle of PCOS after pioglitazone therapy

(Submitter supplied) Insulin resistance is a common metabolic abnormality in women with PCOS and leads to an elevated risk of type 2 diabetes. Studies have shown that thiazolidinediones (TZD) improve metabolic disturbances in PCOS patients. We hypothesized that the effect of TZD in PCOS is in part mediated by changes in the transcriptional profile of muscle favoring insulin sensitivity. Using Affymetrix microarrays, we examined the effect of pioglitazone (30 mg/day for 16 weeks) on gene expression in skeletal muscle of 10 obese women with PCOS metabolically characterized by a euglycemic-hyperinsulinemic clamp. more...
