Project description:The methylome and transcriptome signatures following exercise that are physiologically and metabolically relevant to sporting contexts such as team sports or health prescription scenarios (e.g. high intensity interval training/HIIT) has not been investigated. To explore this, we performed two different sport/exercise relevant high-intensity running protocols in 5 male sport team members using a repeated measures design of: 1) Change of direction (COD) versus; 2) straight line (ST) exercise with a wash-out period of at least 2 weeks between trials. Skeletal muscle biopsies collected from the vastus lateralis 30 minutes and 24 hours post exercise, were assayed using 850K methylation arrays and a comparative analysis with recent (subject-unmatched) sprint and acute aerobic exercise meta-analysis transcriptomes was performed. Despite COD and ST exercise being matched for classically defined intensity measures (speed x distance and number of accelerations/decelerations), COD exercise elicited greater movement (GPS-Playerload), physiological (HR), metabolic (lactate) as well as central and peripheral (differential RPE) measures compared with ST exercise, suggesting COD exercise evoked a higher exercise intensity. The exercise response alone across both conditions evoked extensive alterations in the methylome 30 mins and 24 hrs post exercise, particularly in MAPK, AMPK and axon guidance pathways. COD evoked a considerably greater hypomethylated signature across the genome compared with ST exercise, particularly at 30 minutes post exercise, enriched in: Protein binding, MAPK, AMPK, insulin, and axon guidance pathways. Comparative methylome analysis with sprint running transcriptomes identified considerable overlap, with 49% of genes that were altered at the expression level also differentially methylated after COD exercise. After differential methylated region analysis, we observed that VEGFA and its downstream nuclear transcription factor, NR4A1 had enriched hypomethylation within their promoter regions. VEGFA and NR4A1 were also significantly upregulated in the sprint transcriptome and meta-analysis of exercise transcriptomes. We confirmed increased gene expression of VEGFA, and considerably larger increases in the expression of canonical metabolic genes, PPARGC1A (that encodes PGC1-α) and NR4A3 in COD vs. ST exercise. Overall, we demonstrate that increased physiological/metabolic load via change of direction exercise in human skeletal muscle evokes considerable epigenetic modifications that are associated with changes in expression of genes responsible for adaptation to exercise.

Project description:Voluntary running exercise after focal cerebral ischemia promotes functional recovery and prevents the ischemia-induced dendritic spine loss in the peri-infarct motor cortex layer 5. Neuronal morphology is affected by the perineuronal environmental change. Glia exert crucial roles in the formation of perineuronal environment, and exercise-induced changes of glial phenotype are expected. Here, we demonstrated that voluntary running exercise increased the population of newborn astrocytes in the acute phase after cerebral ischemia at late phase. Transcriptome analysis detected 10 upregulated genes and 70 downregulated genes by exercise in the ipsilateral cortex astrocytes. Gene cluster downregulated by exercise were significantly associated with neuronal morphology. The expression of Lipocalin 2, a factor of decreasing dendritic spines, tended to be decreased in the postischemic astrocytes by exercise. Our results suggest that exercise modifies the phenotype of postischemic astrocytes, which relate to the exercise-induced amelioration of postischemic dendritic spine loss.

Project description:n total, 16 7-week-old male F344 rats were subjected to model regular exercise and sedentary lifestyle. In the second week after arrival and acclimatization to the reversed light/dark cycle, rats were introduced to the forced running wheel without a specific running mode. It was followed by a 12-day training phase for all 16 experimental animals (started at 9 weeks of age) by gradually increasing the running speed and duration. During the training phase, 8 best performers were selected for the runner group while the remaining 8 rats were assigned to the sedentary group. The regular forced running exercise phase for the runner group lasted for 5 weeks in total, including 4 weeks of regular running. After 4 weeks of regular exercise, rats underwent brief anesthesia and of blood from the tail vein were taken. This step was repeated for the same animals immediately after 1h of running. On the same day, a blood sample was collected from the sedentary rats following the same protocol. Plasma was collected and immediately frozen for further EV isolation. EVs were isolated from rat plasma by size exclusion chromatography. RNA libraries were constructed using CleanTag® Small RNA Library Prep Kit (Trilink Biotechnologies, USA) and sequenced on Illumina NextSeq500 instrument using NextSeq 500/550 Mid Output Kit v2.5 (150 cycles).

Project description:Currently, the mechanisms behind the anti-aging effects of exercise are not understood. The presented study conducted a microarray on hippocampal samples from adult (3.5 month-old) and aged (18 month-old) male BALB/c mice that were individually housed with or without running wheels for 8 weeks. Results showed that aging altered genes related to chromatin remodeling, cell growth, immune activity, and synapse organization compared to adult mice. Exercise was found to modulate many of the genes altered by aging, but in the opposite direction. For example, wheel running increased expression of genes related to cell growth and attenuated expression of genes involved in immune function and chromatin remodeling. Collectively, findings show that even late-onset exercise may attenuate age-related changes in gene expression and identifies possible pathways through which exercise may exert its beneficial effects. In total 20 samples (4 aged exercise, 4 aged sedentary, 6 adult exercise, and 6 adult sedentary) plus 4 technical replicates (24 total) were analyzed.
