RNA-seq of triceps brachii muscles from mice after myostatin depletion and wheel running exercise

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.

RNA-sequencing in skeletal muscle from a mouse model of laparotomy with pre-operative running wheel exercise

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.

The effects of muscular dystrophy, exercise and sActRIIB-Fc on molecular signature of skeletal muscle in mice

Project description:To study the combined effect of myostatin/activin inhibition and exercise on muscle mass and pathophysiology, young mdx mice, a model for Duchenne Muscular Dystrophy, were injected with soluble activin receptor-Fc (sActRIIB-Fc) or placebo (PBS) 1x/week for a 7-week period, in combination with or without voluntary running. C57Bl/10ScSnJ mice injected with PBS acted as wildtype controls. Microarray expression analysis from skeletal muscle was performed using m. gastrocnemies as the sample. We found thatexercise or a combination of exercise and sActRIIB-Fc treatment is more effective in correcting gene expression profiles of dystrophic muscles than the sActRIIB-Fc treatment alone. We also identified several pathways and proteins that were affected by exercise and sActRIIB-Fc together or independently. Total RNA obtained from gastrocnemius muscle of mdx mice divided into four groups: 1) control (injected with PBS, n=5), 2) runners (voluntary wheel running for 7 weeks, injected with PBS, n=5), 3) sActRIIB-Fc -treated (n=5), and 4) runners with sActRIIB-Fc-treatment (n=5). sActRIIB-Fc or PBS was injected intraperitoneally once a week with a 5-mg/kg dose of sActRIIB-Fc. In addition, wildtype mice served as healthy controls (n=4).

Molecular characterisation of muscle and spinal cord tissues from young, old and old exercised C57BL/6 wild type male mice

Project description:To investigate the effect of exercise in several tissues, mice had free access to the wheel for two months, starting at the age of 16 to 18 months. Age-matched and younger sedentary controls were included. Running wheels were removed from the cages at least 4 days before necropsy, to eliminate acute effects of exercise. At the end of the trial, RNA was isolated from spinal cord, gastrocnemius and quadriceps muscle to perform bulk transcriptome (RNAseq) analysis. Despite many genes were differentially expressed in skeletal muscle samples following exercise, only few individual genes resulted changed by exercise in spinal cord.

Effect of wheel running exercise on gene expression in skeletal muscles of mice

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. 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).
