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...

PPAR-γ agonist pioglitazone effect on obese women with polycystic ovary syndrome: skeletal muscle

Analysis of skeletal muscle from obese women with polycystic ovary syndrome (PCOS) before and after thiazolidinedione (TZD) pioglitazone treatment. TZDs improve metabolic disturbances in PCOS patients. Results provide insight into the molecular mechanisms underlying the effect of TZD in PCOS.

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...

Differential Gene Expression in Granulosa Cells from Polycystic Ovary Syndrome Patients with and without Insulin Resistance: Identification of Susceptibility Gene Sets through Network Analysis

(Submitter supplied) Polycystic ovary Syndrome (PCOS) is a heterogeneous endocrine disorder that shows evidence of genetic predidposition among affected individuals. We have utilized the Microarray data from granulosa cells of normal and PCOS women for network construction.

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...

Pioglitazone treatment of Lethal Yellow mice

(Submitter supplied) Goal of the experiment: To examine differential gene expression in the ovaries of heterozygous Lethal Yellow (C57BL/6J Ay/a) mice treated with vehicle or pioglitazone. Brief description of the experiment: The objective of this study was to use whole mouse genome DNA microarrays (Codelink) to examine gene expression the ovaries of heterozygous Lethal Yellow (C57BL/6J Ay/a) mice. Women with polycystic ovary syndrome (PCOS) treated with thiazolidinediones (TZD), such as pioglitazone, show reduced androgen levels and improved ovulatory function. more...
