Analysis of skeletal muscles of C57BL/6J animals fed a low or high fat diet for 3 or 28 days. Oversupply of lipid to skeletal muscle can result in insulin resistance, a characteristic of metabolic syndrome (MS). Results provide insight into the molecular events underlying the early onset of MS.

(Submitter supplied) The prevalence of the metabolic syndrome (MS) is rapidly increasing all over the world. Consequently, there is an urgent need for more effective intervention strategies. Both animal and human studies indicate that lipid oversupply to skeletal muscle can result in insulin resistance which is one of the charecteristices of the MS. C57BL/6J mice were fed a low fat (10 kcal%) palm oil diet or a high fat (45 kcal%; HF) palm oil diet for 3 or 28 days. more...

(Submitter supplied) An 8-week high fat palm oil diet causes obesity and insulin resistance in C57BL/6J mice, but induces only small changes in the muscle transcriptome. Introduction: The metabolic syndrome (MS) is a cluster of metabolic abnormalities linked to an increased risk of type 2 diabetes and cardiovascular diseases. Two major characteristics of the MS are obesity and insulin resistance. In the present study we investigated the effect of obesity and insulin resistance on the mouse muscle transcriptome. more...

(Submitter supplied) We studied the effect of dietary fat type, varying in polyunsaturated/saturated fatty acid ratio's (P/S) on development of metabolic syndrome. C57Bl/6J mice were fed purified high-fat diets (45E% fat) containing palm oil (HF-PO; P/S 0.4), olive oil (HF-OO; P/S 1.1) or safflower oil (HF-SO; P/S 7.8) for 8 weeks. A low-fat palm oil diet (LF-PO; 10E% fat) was used as a reference. Additionally, we analyzed diet-induced changes in gut microbiota composition and mucosal gene expression. more...

Analysis of small intestine divided into 3 equal parts along the proximal to distal axis (SI 1, SI 2, SI 3) from C57Bl/6J males fed high-fat diets varying in polyunsaturated/saturated fatty acid ratios (P/S). Results provide insight into role of dietary fat type on development of metabolic syndrome.

Analysis of skeletal muscles of transgenics (trs) overexpressing PPARalpha. Trs overexpressing PPARalpha develop glucose intolerance despite protection from diet-induced obesity. Results provide insight into the role of PPARalpha in the development of insulin-resistant diabetes.

(Submitter supplied) Introduction: The mouse skeletal muscle is composed of four distinct fiber types that differ in contractile function, number of mitochondria and metabolism. Every muscle group has a specific composition and distribution of the four fiber types. Until now, three genes (CnA, PGC1α and PPARδ) are identified that are involved in the generation of more oxidative muscle types. In the present study we searched for novel genes that are involved in specifying different muscle types. more...

(Submitter supplied) Exercise training can stimulate the formation of fatty acid oxidizing slow-twitch skeletal muscle fibers which are inversely correlated with obesity, but the molecular mechanism underlying this transformation requires further elucidation. Here, we report that the downregulation of the mitochondrial disulfide relay carrier CHCHD4 in skeletal muscle by exercise training decreases the import of TP53-regulated inhibitor of apoptosis 1 (TRIAP1) into mitochondria, which reduces cardiolipin levels and promotes VDAC oligomerization. more...
