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.

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).

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:To identify the mechanism underlying AdipoR1-mediated beneficial effect of exercise, we used RNA-Seq analysis to study the transcriptomic profiles of mice after 4-month wheel running exercise. Differential expression analysis was performed by comparing exercised mice to control mice, and exercised mice subjected to AdipoR1 shRNA versus exercised mice.

Project description:Exercise has been correlated with retardation of tumor initiation and progression. However, it is unclear what are the molecular mechanisms behind this beneficial effect of exercise. In this study, we obtained RNA-seq data from biopsies of Lewis lung carcinoma tumors in a total of 16 mice, 8 with access to running wheel and 8 without (controls).
