Project description:Exercise training increases endurance by inducing global gene expression changes in skeletal muscles. The extent to which the genetic effects of exercise can be mimicked by synthetic drugs is unknown. We measured global skeletal muscle expression in sedentary and exercised mice treated with vehicle or PPARdelta ligand GW1516. PPARdelta is a transcriptional regulator of muscle oxidative metabolism and fatigue resistance. Keywords: Pharmacology study

We measured global skeletal muscle expression in sedentary and exercised mice treated with vehicle or PPARdelta ligand GW1516. PPARdelta is a transcriptional regulator of muscle oxidative metabolism and fatigue resistance. Experiment Overall Design: Sedentary and exercise trained C57Bl/6J mice were treated with vehicle or GW1516 for 4 weeks, followed by collection of quadriceps for gene expression analysis.

Project description:This analysis was done to determine which muscle group has the most skeletal muscle transcriptional reponses to wheel running activity. Seven male mice with C57BL/6 genetic background were placed individually in cages with running wheels and allowed free access to the wheels 24 hr per day. Access to running wheels began when the mice were 6 months old, and continued for 12 weeks. The morning after the night of running, the mice were euthanized and several muscle groups were snap froze in liquid nitrogen to preserve RNA. The same muscle groups were collected from three age-matched "sedentary" mice that were housed in ordinary cages that did not permit sustained running. For each muscle group, separate pools of polyadenylated RNA from the sedentary and wheel-running mice were prepared for deep sequencing of cDNA with the SOLiD 3 platform.

Project description:The purpose of this study was to determine whether postdevelopmental myostatin depletion influenced the changes in skeletal muscle gene expression profiles induced by a long-term increase in physical activity. Myostatin levels in muscles of adult male mice with floxed myostatin genes were reduced ~85% by activating Cre recombinase. Control mice with normal myostatin genes had the same Cre-activating treatment. Some of the mice were housed in ordinary cages throughout the study, limiting their physical activity. Other mice were given free access to running wheels for the final 12 weeks of the study. At the end of the study, comprehensive gene expression profiles of triceps brachii muscles were determined by RNA sequencing (RNA-Seq), with muscles from mice selected for similarity of running behavior throughout the period of wheel access. Wheel running increased expression of hundreds of mRNAs encoding proteins involved in oxidative energy metabolism, and this response was not affected by myostatin deficiency. The running-induced increase in the ratio of Myh1 mRNA (which encodes myosin heavy chain type 2x) to Myh4 mRNA (which encodes myosin heavy chain type 2b) also was not affected by myostatin depletion. At every threshold of P (computed by analysis of variance), the number of transcripts with interactions between activity level and myostatin level was fewer than the number expected by chance. These data suggest that myostatin is not required for transcriptional adaptations to moderate-intensity exercise. 12 samples, 6 from sedentary mice and 6 from active (wheel running) mice. 3 control and 3 myostatin-deficient mice within each activity level.

For each muscle group, separate pools of polyadenylated RNA from the sedentary and wheel-running mice were prepared for deep sequencing of cDNA with the SOLiD 3 platform. Four muscle groups were examined (quadriceps femoris; gastrocnemius/plantaris; tibialis anterior; triceps brachii). For each muscle, RNA was pooled from 3 sedentary or 7 wheel-running mice (8 pools total).

Project description:This study aimed to characterize the effects of pre-operative volitional running wheel exercise on post-operative physical function and skeletal muscle gene expression in 24-month-old C57BL/6N mice following laparotomy. Soleus muscles collected on post-operative day 5 (POD 5) were used for this study.

Project description:We generated a large transcriptome atlas of human skeletal muscles by collecting biopsies from 6 different muscles to determine molecular signatures that may be distinct between leg muscles. The biopsies were collected from gracilis (GR), semitendinosus (ST), vastus lateralis (VL), vastus medialis (VM), rectus femoris (RF), and gastrocnemius lateralis (GL) muscles. We also investigated molecular differences within the muscle by including two biopsies from the middle and distal sides of the semitendinosus muscle (STM and STD, respectively). In total, 128 samples from 20 individuals (aged 25 ± 3.6 yr) were analyzed.
