Conserved multitissue transcriptomic adaptations to exercise training in humans and mice

ABSTRACT: Physical activity is associated with beneficial adaptations in human and rodent metabolism. We studied over 50 complex traits before and after exercise intervention in middle-aged men and a panel of 100 diverse strains of female mice. Candidate gene analyses in three brain regions, muscle, liver, heart, and adipose tissue of mice revealed genetic drivers of clinically relevant traits including volitional exercise volume, muscle metabolism, adiposity, and hepatic lipids. Although ~33% of genes differentially expressed in skeletal muscle following the exercise intervention were similar in mice and men independent of BMI, responsiveness of adipose tissue to exercise-stimulated weight loss appears impacted by species and underlying genotype. We leveraged genetic diversity to generate prediction models of metabolic trait responsiveness to volitional activity offering a framework for advancing personalized exercise prescription. Finally, we make the human and mouse data publicly available via user-friendly web-based application to enhance data mining and hypothesis development.

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.

Gene expression profile in Liver, skeletal muscle, brown and white adipose tissues in mice after different interventions

Project description:SIRT1 is a NAD+-dependent protein deacetylase. SIRT1 plays key roles in metabolic regulation and adaptation. In this study, we wanted to compare gene expression profile in SIRT1 overexpressing mice to WT mice submitted to different intervention (caloric restriction and exercise training) in different tissues (liver, skeletal muscle, brown and white adipose tissues). SIRT1 transgenic model has already been described (Pfluger et al., 2008). Here we used homozygote transgenic mice which had been backcrossed to C57Bl/6N background. 3 months old WT and SIRT1tg mice were fed with a low fat diet. After sacrifice, total mRNA obtained from brown adipose were used for microarray. Caloric restriction (CR) : everyother day feeding during 3 months Exercise training (EX) : mice were housed in running wheel cages during 10 weeks

Exercise-induced Crosstalk between Immune Cells and Adipocytes in Humans: Role of Oncostatin-M

Project description:The discovery of novel exercise-regulated circulatory factors has fueled interest in the role of organ-crosstalk, especially between skeletal muscle and adipose tissue in mediating beneficial effects of exercise. We studied the adipose tissue transcriptome in men and women with normal glucose tolerance or type 2 diabetes following an acute exercise bout, revealing substantial exercise and time-dependent changes, and a sustained increase in inflammatory genes unique to Type 2 diabetes. We identify Oncostatin-M as one of the most upregulated adipose tissue secreted factors post exercise. In cultured human adipocytes, oncostatin-M enhanced MAPK signalling and regulates lipolysis. Oncostatin-M expression predominantly arises from adipose tissue immune cell fractions, while the corresponding receptors are expressed in adipocytes. Oncostatin-M expression is induced in cultured human Thp1 macrophages in response to exercise-like stimuli. Our results suggest immune cells, via secreted factors such as oncostatin-M, are important in crosstalk between skeletal muscle and adipose tissue during exercise, to regulate adipocyte metabolism and adaptation.

Age-dependent impact of two exercise training regimens on genomic and metabolic remodeling in skeletal muscle and liver of male mice

Project description:How skeletal muscle adapts to different types of exercise intensity with age is not known. Adult and old C57BL/6 male mice were assigned to one of three groups: sedentary, daily high-intensity intermittent training (HIIT), or moderate intensity continuous training (MICT) for 4 weeks, compatible with the older group’s exercise capacity. Improvements in body composition, fasting blood glucose, and muscle strength were mostly observed in the MICT old group, while effects of HIIT training in adult and old animals was less clear. Skeletal muscle exhibited structural and functional adaptations to exercise training, as revealed by electron microscopy, OXPHOS assays, respirometry, and muscle protein biomarkers. Transcriptomics analysis of gastrocnemius muscle combined with liver and serum metabolomics unveiled an age-dependent metabolic remodeling in response to exercise training. These results support a tailored exercise prescription approach aimed at improving health and ameliorating age-associated loss of muscle strength and function in the elderly.
