Exercise intensity differentially modulates systemic molecular responses and predicted interorgan communication in humans

ABSTRACT: Exercise is recognized as a first-line lifestyle therapy for many cardiometabolic diseases, including obesity, type 2 diabetes, and hypertension. Despite the abundant health-promoting effects of exercise, in-depth characterization of circulatory factors mediating these benefits remain understudied in humans. Moreover, how different modes of exercise uniquely regulate these processes is unclear. Here, we address these questions by conducting a multi-cohort human exercise intervention, incorporating sprint-interval exercise (SIE), moderate-intensity exercise (MIE), and treadmill exercise to exhaustion to analyze intensity-dependent regulation of adipocytes and bulk adipose tissue. We find that exercise intensity uniquely influences the plasma proteome and plasma metabolome, and culturing primary human adipocytes with these plasma samples results in robust intensity-dependent transcriptome changes. We confirm many of these genes are similarly regulated by intense exercise in vivo, via RNA-sequencing of bulk adipose tissue following treadmill exercise to exhaustion. These findings underscore intensity-dependent regulation of adipose tissue following exercise.

Passing the anaerobic threshold is associated with substantial changes in the gene expression profile in white blood cells

Project description:High and moderate intensity endurance exercise alters gene expression in human white blood cells (WBCs), but the understanding of how this effect occurs is limited. To increase our knowledge of the nature of this process, we investigated the effects of passing the anaerobic threshold (AnT) on the gene expression profile in WBCs of athletes. Nineteen highly trained skiers participated in a treadmill test with an incremental step protocol until exhaustion (ramp test to exhaustion; RTE). The average total time to exhaustion was 14:40 min and time after AnT was 4:50 min. Two weeks later, seven of these skiers participated in a moderate treadmill test (MT) at 80% peak O2 uptake for 30 min, which was slightly below their AnTs. Blood samples were obtained before and immediately after both tests. RTE was associated with substantially greater leukocytosis and acidosis than MT. Gene expression in WBCs was measured using whole genome microarray expression analysis before and immediately after each test. A total of 310 upregulated genes were found after RTE, and 69 genes after MT, of which 64 were identical to RTE. Both tests influenced a variety of known gene pathways related to inflammation, stress response, signal transduction and apoptosis. A large group of differentially expressed, and previously unknown, small nucleolar RNA and small Cajal body RNA was found. In conclusion, a 15 min test to exhaustion was associated with substantially greater changes of gene expression than a 30 min test just below the AnT. After a general medical checkup, the subjects performed a ramp-type progressive exercise test on a treadmill. Blood samples were taken from the antecubital vein using indwelling catheter before (T0) and immediately after ramp test to exaustion (T1), and before (T2) and immediately after moderate treadmill test (T3).

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.

Identifying overtraining biomarkers through proteomic analysis of extracellular vesicles derived from the central nervous system of male mice

Project description:Overtraining, which results in central nervous system (CNS)-fatigue-related symptoms, lead to a long-term decline in performance. This study investigated CNS-derived EV protein content under overtraining conditions to identify potential biomarkers. Eight-week-old C57BL/6J mice were randomly divided into three groups: sedentary (SED, n=7), exercise control (EX, n=8), and overtraining (OT, n=9) groups. The OT underwent an 8-week downhill treadmill-based overtraining induction protocol. Exercise capacity was assessed using the incremental load, exhaustion, grip strength, and rotarod tests, while motor deficits, depression and anxiety were assessed using the nest building test. Proinflammatory cytokines were measured in blood plasm, skeletal muscle, and brain tissue. CNS-derived EVs were isolated using a two-step EV isolation protocol. Isolated EVs underwent proteomic analyses. Mice exhibited a significant decrease in aerobic exercise capacity, high-intensity exercise tolerance, and muscular strength. OT increased quadriceps IL-6 and hypothalamic IL-1β/TNFα compared to EX. Plasma IL-2 levels tended to be higher in OT than in EX. Proteomic analysis of CNS-derived EVs revealed a decrease in lipid metabolism-related proteins. Valosin-containing proteins and catalase, which are upregulated in organs under oxidative stress, were increased. Therefore, CNS-derived EV protein contents indicated CNS fatigue under overtraining conditions.

Expression data from exercised-trained, myog-deleted adult mice

Project description:Although skeletal muscle metabolism is a well-studied physiological process, little is known about how it is regulated at the transcriptional level. The myogenic transcription factor myogenin is required for skeletal muscle development during embryonic and fetal life, but myogenin’s role in adult skeletal muscle is unclear. We sought to determine myogenin’s function in adult muscle metabolism. A Myog conditional allele and Cre-ER transgene were used to delete Myog in adult mice. Mice were analyzed for exercise capacity by involuntary treadmill running. To assess oxidative and glycolytic metabolism, we monitored blood glucose and lactate levels and performed histochemical analysis on muscle fibers. Surprisingly, we found that Myog-deleted mice performed significantly better than controls in high- and low-intensity treadmill running. This enhanced exercise capacity was due to more efficient oxidative metabolism during low-intensity exercise and more efficient glycolytic metabolism during high-intensity exercise. Furthermore, Myog-deleted mice had an enhanced response to long-term voluntary exercise training on running wheels. We identified several candidate genes whose expression was altered in exercise-stressed muscle of mice lacking myogenin. The results suggest that myogenin plays a critical role as a high-level transcriptional regulator to control the energy balance between aerobic and anaerobic metabolism in adult skeletal muscle. We used microarrays to detail the global program of gene expression underlying enhanced exercise endurance associated with myog-deletion and long-term exercise training.

Project description:The molecular mechanisms involved in the coordinate regulation of the metabolic and structural determinants of muscle endurance are still poorly characterized. To help elucidate the role of ERRa in this process, gene expression arrays were employed resulting in the identification of ERRa-dependent genes involved in metabolic processes, oxidative stress response, maintenance of muscle fiber integrity and neovascularization. Gastrocnemius (n=3) isolated from 2-3 month old WT and ERRa-null mice under pre-exercise (sedentary) and post-exercise (2 h following acute exhaustion on a treadmill) were used for gene expression studies using Affymetrix mouse 2.0 gene ST arrays.

Time of day dependent regulation of exercise-induced transcription in the heart

Project description:We sought to determine the global transcriptional response to exercise in the heart in a time-of-day dependent manner. To accomplish this, adult male mice (C57Bl/6, ~12 weeks of age) were habituated to treadmill exercise and exposed to a single bout of low-moderate intensity exercise (60 mintue, 10 m/min, 0% grade) at ZT0 (beginning of rest phase) or ZT12 (beginning of active phase). RNA was isolated from whole hearts harvested immediately after exercise (or from sedentary control mice) for RNA-Seq.

Brown and beige adipose tissue regulate systemic metabolism through a metabolite interorgan signaling axis

Project description:Brown and beige adipose tissue are emerging as distinct endocrine organs. These tissues are functionally associated with skeletal muscle, adipose tissue metabolism and systemic energy expenditure, suggesting an interorgan signaling network. Using metabolomics, we identify 3-methyl-2-oxovaleric acid, 5-oxoproline, and β-hydroxyisobutyric acid as small molecule metabokines synthesized in browning adipocytes and secreted via monocarboxylate transporters. 3-methyl-2-oxovaleric acid, 5-oxoproline and β-hydroxyisobutyric acid induce a brown adipocyte-specific phenotype in white adipocytes and mitochondrial oxidative energy metabolism in skeletal myocytes both in vitro and in vivo. 3-methyl-2-oxovaleric acid and 5-oxoproline signal through cAMP-PKA-p38 MAPK and β-hydroxyisobutyric acid via mTOR. In humans, plasma and adipose tissue 3-methyl-2-oxovaleric acid, 5-oxoproline and β-hydroxyisobutyric acid concentrations correlate with markers of adipose browning and inversely associate with body mass index. These metabolites reduce adiposity, increase energy expenditure and improve glucose and insulin homeostasis in mouse models of obesity and diabetes. Our findings identify beige adipose-brown adipose-muscle physiological metabokine crosstalk.

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.
