Project description:Background: Exercising is know to have an effect on exercising skeletal muscle, but unkown is the effect on non-exercising skeletal muscle. Gene expression changes in the non-exercising skeletal muscle would point to a signalling role of skeletal muscle 9 healthy middle-aged men performed 1 hour of one-legged exercise, before and afterwards muscle biopsies were taken from both legs. Skeletal muscle biopsies were analyzed by microarray.

Project description:Analysis of the changes in the transcriptome of circulating neutrophils and skeletal muscle from standardized resting conditions (baseline; pre-EXTRI) to 3, 48 and 96 hours after an experimental exercise trial (EXTRI; 1 hour of cycling followed by 1 hours of running) in 8 healthy, endurance-trained, male subjects. It was hypothesized that the time-course dependent transcriptomic changes would reflect the molecular and signalling mechanisms by which neutrophils regulate and counter-regulate inflammation, and by which skeletal muscle responds, regenerates, and phenotypically adapts to intense, prolonged exercise involving muscle damage. Results provide an important insight in the signalling pathways underlying the transcriptional activation and priming of circulatory neutrophils in response to physiological stress, in particular muscle-derived damage-associated molecular patterns. Furthermore, the study provides novel data on the skeletal muscle transcriptome beyond 48 hours after strenuous endurance exercise, and indicates important muscular remodelling processes at 96 hours post-EXTRI. Blood and muscle samples were taken under standardized conditions at baseline (pre-EXTRI), and 3, 48 and 96 hours post-EXTRI. Total mRNA was extracted from isolated neutrophils, and from skeletal muscle tissue.

Project description:The few investigations on exercise-induced global gene expression responses in human skeletal muscle haves typically focused at one specific mode of exercise and few such studies have implemented control measures. However, interpretation on distinct phenotype regulation necessitate comparison between essentially different modes of exercise and the ability to identify true exercise effects, necessitate implementation of independent non-exercise control subjects. Furthermore, muscle transkriptometranscriptome data made available through previous exercise studies can be difficult to extract and interpret by individuals that are inexperienced with bioinformatic procedures. In a comparative study, we; (1) investigated the human skeletal muscle transcriptome response to differentiated exercise and non-exercise control intervention, and; (2) aimed to develop a straightforward search tool to allow for easy extraction and interpretation of our data. We provide a simple spreadsheet containing transcriptome data allowing other investigators to see how mRNA of their interest behave in skeletal muscle following exercise, both endurance, strength and non-exercise. Our approach, allow investigators easy access to information on genuine transcriptome effects of differentiated exercise, to better aid hyporthesis-driven question in this particular field of research.

Biopsies for microarray were take before (Pre) and 2½ and 5 hours after the last training session. Isolated RNA from these biopsies were then measured with the Affymetrix Human Gene 1.0 ST arrays.

Project description:The aim of this investigation was to evaluate the effect of training on the global transcriptional response of skeletal muscle to an acute bout of resistance exercise. Seven young healthy men and women underwent a 12-week supervised progressive unilateral arm resistance exercise (RE) training program. One week after the last session of training, subjects performed an acute bout of bilateral arm RE in which the trained and the untrained arm exercised at the same relative intensity. A muscle biopsy was obtained 4h post exercise from the biceps brachii of the trained and untrained arm. Trained and untrained muscle samples were analyzed for mRNA levels of over 20,000 annotated genes using Affymetrix U133 Plus 2.0 microarrays.

Project description:Exercise is an important strategy in the prevention and treatment of metabolic diseases, like diabetes and obesity. Alterations in the skeletal muscle proteome, including post-translational modifications, especially acetylation, regulate its metabolic adaptations to exercise. Here, we examined the effect of 6-week aerobic exercise and Scriptaid, a HDAC4/5 inhibitor, on the proteome and acetylome of skeletal muscle in mice. We find Scriptaid and exercise both induce acetylation modification changes of some proteins involved in metabolism, suggest that exercise improves metabolic health by regulating protein acetylation level.
