Effects of moderate intensity exercise on liver metabolism in mice based on multi-omics analysis

ABSTRACT: Physical exercise is beneficial to keep physical and mental health. The molecular mechanisms underlying exercise are still worth exploring.The healthy adult mice after six weeks of moderate-intensity exercise (experimental group) and sedentary mice (control group) were used to perform transcriptomic, proteomic, lactylation modification, and metabolomics analysis. In addition, gene sets related to hypoxia, glycolysis, and fatty acid metabolism were used to aid in the screening of hub genes. The mMCP-counter was employed to evaluate infiltration of immune cells in murine liver tissues.

Effects of moderate intensity exercise on liver metabolism in mice based on multi-omics analysis

Project description:Background: Physical exercise is beneficial to keep physical and mental health. The molecular mechanisms underlying exercise are still worth exploring. Methods: The healthy adult mice after six weeks of moderate-intensity exercise (experimental group) and sedentary mice (control group) were used to perform transcriptomic, proteomic, lactylation modification, and metabolomics analysis. In addition, gene sets related to hypoxia, glycolysis, and fatty acid metabolism were used to aid in the screening of hub genes. The mMCP-counter was employed to evaluate infiltration of immune cells in murine liver tissues. Results: Transcriptomics analysis revealed 82 intersection genes related to hypoxia, glycolysis, and fatty acid metabolism. Proteomics and lactylation modification analysis identified 577 proteins and 141 differentially lactylation modification proteins. By overlapping 82 intersection genes with 577 differentially expressed proteins and 141 differentially lactylation modification proteins, three hub genes (Aldoa, Acsl1, and Hadhb) were obtained. The immune infiltration analysis revealed a decreased score for monocytes/macrophages and an increased score for endothelial cells in the experimental group. Then, 459 metabolites in positive mode and 181 metabolites in negative mode were identified. The “Metabolic pathways” (mmu01100) was a common pathway between intersection genes-enriched pathways and metabolites-enriched pathways. Conclusion: These findings highlight the pivotal roles of hub genes in the glycolysis and fatty acid metabolism under the context of chronic exercise.

Multi-omics study on the effect of moderate intensity exercise on protein of lactylation in mouse muscle tissue

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.

Moderate-Intensity Interval Exercise Exacerbates Cardiac Lipotoxicity in High-Fat, High-Calories Diet-Fed Mice

Project description:Physical exercise is a cornerstone for preventing diet-induced obesity, while it is unclear whether physical exercise could offset high-fat, high-calories diet (HFCD)-induced cardiac dysfunction. Here, mice were fed with HFCD and simultaneously subjected to physical exercise. As expected, physical exercise prevented HFCD-induced whole-body fat deposition. However, physical exercise exacerbated HFCD-induced cardiac damage. Further metabolomic analysis results showed that physical exercise induced circulating lipid redistribution, leading to excessive cardiac lipid uptake and lipotoxicity. Our study provides valuable insights into the cardiac effects of exercise in mice fed with HFCD, suggesting that counteracting the negative effect of HFCD by simultaneous physical exercise might be detrimental. Moreover, inappropriate physical exercise may damage certain organs even though it leads to weight loss and overall metabolic benefits. Of note, the current findings are based on animal experiments, the generalizability of these findings beyond this specific diet and mouse strain remains to be further explored.

Exercise intensity and sex alter neurometabolic, transcriptional, and functional recovery following traumatic brain injury.

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.

Transgenerational effects of exercise on mouse brain and cognition

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.

Effect of IL6 level on gene expression changes in Peripheral Blood Mononuclear cells (PBMC) induced by physical activity

Project description:A number of chronic, age-related diseases are associated with elevated markers of inflammation such as interleukin-6 (IL-6). In this study, we investigated the hypothesis that sedentary individuals with disparate basal serum IL-6 respond differentially to a structured physical activity programme. Gene expression changes in Peripheral Blood Mononuclear cells (PBMC) induced by physical activity was investigated in sedentary, middle-aged men (mean age 52.6 years and BMI 29.1), with relatively high or low basal serum IL-6 levels (mean of 2.13 and 0.59pg/ml respectively), who undertook a 24-week physical activity programme with blood sampling in the pre-exercise period and at the end of 24-weeks prescribed physical activity. AgilentTM Whole Human Genome Oligo Microarrays were utilised to examine the effects of physical activity on mRNA expression profiles of the Peripheral Blood Mononuclear cells (PBMC) at 2 time points (pre-exercise, and after 24 weeks physical activity. There were 6 individuals per group.

Gene expression profile induced by moderate physical exercise in heart left ventricles in rats

Project description:Physical exercise training is a known protective factor against cardiovascular morbidity and mortality. Nevertheless, the underlying specific molecular mechanisms still remain uncompletely explored. To identify molecular mechanisms by which exercise training induces this favorable phenotype a genomic approach was used in an animal model of mild exercise previously demonstrated by our group to induce cardioprotection. Our data indicate that mild exercise by inducing no or few permanent changes in gene expression profile is able to determine cardioprotection without induction of cardiac hypertrophy. Keywords: Case-Control: Response to physical exsercise
