Project description:Moderate-intensity exercise affects gut microbiome
| PRJEB21675 | ENA
Project description:Exercise exerts a wide range of beneficial effects for healthy physiology. However, the mechanisms regulating an individual's motivation to engage in physical activity remain incompletely understood. An important factor stimulating the engagement in both competitive and recreational exercise is the motivating pleasure derived from prolonged physical activity, which is triggered by exercise induced neurochemical changes in the brain. Here, we report on the discovery of a gut brain connection in mice that enhances exercise performance by augmenting dopamine signalling during physical activity. We find that microbiome dependent production of endocannabinoid metabolites in the gut stimulates the activity of TRPV1 expressing sensory neurons and thereby elevates dopamine levels in the ventral striatum during exercise. Stimulation of this pathway improves running performance, whereas microbiome depletion, peripheral endocannabinoid receptor inhibition, ablation of spinal afferent neurons or dopamine blockade abrogate exercise capacity. These findings indicate that the rewarding properties of exercise are influenced by gut derived interoceptive circuits and provide a microbiome dependent explanation for interindividual variability in exercise performance. Our study also suggests that interoceptomimetic molecules that stimulate the transmission of gut derived signals to the brain may enhance the motivation for exercise.

Project description:To explore the effects of moderate intensity exercise on protein of lactylation in mouse muscle tissue metabolism. The healthy adult mice running for 6 weeks as exercise model and sedentary mice as control were used to perform transcriptomic, proteomic, lactylation-proteomics, and metabolomics analysis. In addition, correlation analysis between transcriptome and proteome, and proteome and metabolome was conducted as well. In this study, 159 lactate sites of 78 proteins were identified to be differentically regulated by moderate intensity exercise. Enrichment analysis showed that lactated proteins Mtatp8, Atp5mg and Atp5po exhibited ATP hydrolysis activity. They are involved in biological processes such as mitochondrial transmembrane transport, and Mtatp8, Atp5mg and Atp5po participate in Oxidative phosphorylation and Thermogenesis pathways. The lactation levels of Mtatp8, Atp5mg and Atp5po proteins in exercise group were significantly decreased, while their protein levels were significantly increased. The combined analysis of proteomics and metabolomics showed that the Oxocarboxylic acid metabolism pathway and Sphingolipid signaling pathway had significant changes under the influence of moderate intensity exercise. Our results showed that moderate intensity exercise has a certain effect on the lactylation level of mice, possibly by reducing lactylation levels of Mtatp8, Atp5mg and Atp5po and increasing the expression of their protein levels, thereby regulating the Oxidative phosphorylation pathway and participating in energy metabolism. 2-Oxocarboxylic acid metabolism pathway and Sphingolipid signaling pathway need to be further explored.

Project description:Lifestyle induces long lasting effects on the brain and cognition, with some interventions like stress including transgenerational inheritance on the next generations mediated by epigenetic mechanisms. Physical exercise is one potent intervention driving robust improvements of cognition and brain health, also inducing intergenerational transmission to the litter. However, little is known about whether exercise effects may be transgenerationally transmitted. Here we analyzed the adult hippocampal neurogenesis (AHN) and the behavioral phenotype of sedentary adult male mice of the F2 generation of exercised grandfathers (F0, patrilineal design). Both F1 and F2 were sedentary, while F0 performed a moderate exercise training. We found that the F2 mice from exercised F0 acquired and recalled both spatial and non-spatial information better than F2 from sedentary F0. Contextual fear conditioning resulted not affected, together with no differences in the AHN markers. These results demonstrate that the transgenerational transmission of the effects of exercise on specific cognitive tasks persists after two generations, even though some of the cellular changes induced in F1 disappear in F2, and suggest that moderate exercise training has a longer-lasting effect than previously thought, and this aspect is worth taking into account in public health programs.

Project description:While moderate endurance exercise has been reported to improve cardiovascular health , its effects on cardiac structure and function are not fully characterized, especially with respect to sex dimorphism. We aimed to assess the effects of moderate endurance exercise on cardiac physiology in male versus female mice.

Project description:Exercise has the potential to significantly impact those suffering from autoimmune and inflammatory diseases including multiple sclerosis (MS). However, persons with multiple sclerosis (PwMS) do not engage in sufficient activity due to barriers such as increased fatigue, reduced mobility and disability. Characterizing the potential molecular benefits for acute exercise is critical for understanding its therapeutic effects on inflammatory lesions. Investigating the effects of exercise on the central nervous system (CNS) will help in guiding future design and implementation of programs to maximize the benefits of exercise for PwMS.

Project description:In order to assess the impact of treadmill exercise on traumatic brain injury outcomes, we subjected male and female swiss webster mice to a controlled cortical impact (CCI), followed by 10 days of sedentary, low-, moderate-, or high-intensity treadmill exercise. Outcome measures included neurometabolic function, cognitive recovery, oxidative stress, pathophysiology, and single nuclei RNA sequencing (snRNA seq). The snRNA seq study was conducted on both male and female mice, and included a total of 2 replicates (each was a pool of 2 tissue samples) from each of the following groups: male sham sedentary, male CCI sedentary, male CCI low, male CCI high, female sham sedentary, female CCI sedentary, female CCI low, female CCI high. Our data reveal exercise intensity- and sex-dependent effects of treadmill exercise following injury. Transcriptomic changes were largely limited to the low-intensity exercised CCI males.
