Type 2 (non-insulin-dependent) diabetes mellitus is a progressive metabolic disorder arising from genetic and environmental factors that impair beta cell function and insulin action in peripheral tissues. We identified reduced diacylglycerol kinase delta (DGKdelta) expression and DGK activity in skeletal muscle from type 2 diabetic patients. In diabetic(More)
The myocyte enhancer factor (MEF)2 transcription factor is important for development of differentiated skeletal muscle. We investigated the regulation of MEF2 DNA binding in differentiated primary human skeletal muscle cells and isolated rat skeletal muscle after exposure to various stimuli. MEF2 DNA binding activity in nonstimulated (basal) muscle cultures(More)
DNA methylation is altered by environmental factors. We hypothesized that DNA methylation is altered in skeletal muscle in response to either insulin or glucose exposure. We performed a genome-wide DNA methylation analysis in muscle from healthy men before and after insulin exposure. DNA methylation of selected genes was determined in muscle from healthy(More)
BACKGROUND Early benefits of Roux-en Y gastric bypass (RYGB) are partly mediated by the caloric restriction that patients undergo before and acutely after the procedure. Altered DNA methylation occurs in metabolic diseases including obesity, as well as in skeletal, muscle eight months after RYGB. The objective of this study was to test whether promoter(More)
