Gene expression of peripheral blood leukocytes in athletes

ABSTRACT: Probiotics may alter stress sensitivity by modulating the gut-brain axis. The heat-inactivated, enteric-colonizing Lactobacillus gasseri, CP2305 (paraprobiotic CP2305), has been shown to ameliorate psychological stress-related symptoms. This study was designed to reveal the beneficial effects of paraprobiotic CP2305 on top athletes experiencing physical and mental stresses.

Gene expression in peripheral blood leukocytes in young endurance athletes

Project description:Exercise is beneficial to human’s health, and many of the effects are mediated by changes in immune function. However, the mechanisms underpinning the immune-regulatory effect of exercise remain unclear. We used microarrays to assess the global gene expression in blood leukocytes in young endurance athletes and non-athlete controls, the differential gene expression between two groups was analzyed using bioinformatic methods and enriched biological processes and pathways were identified for up- and down-regulated genes in athletes.

Lactobacillus from the Altered Schaedler Flora maintain IFNγ homeostasis to promote behavioral stress resilience.

Project description:The gut microbiome consists of trillions of bacteria, fungi, and viruses that inhabit the digestive tract. These communities are sensitive to disruption from environmental exposures ranging from diet changes to illness. Disruption of the community of lactic acid producing bacteria, Lactobaccillacea, has been well documented in mood disorders and stress exposure. In fact, oral supplement with many Lactobacillus species can ameliorate these effects, preventing depression- and anxiety-like behavior. Here, we utilize a gnotobiotic mouse colonized with the Altered Schaedler Flora to remove the two native species of Lactobaccillacea. Using this novel microbial community, we found that the Lactobacillus species themselves, and not the disrupted microbial communities are protective from environmental stressors. Further, we determine that Lactobaccillacea are maintaining homeostatic IFNγ levels which are mediating these behavioral and circuit level responses. By utilizing the Altered Schaedler Flora, we have gained new insight into how probiotics influence behavior and provide novel methods to study potential therapies to treat mood disorders.

Expression data from human skeletal muscle in endurance-trained athletes

Project description:Endurance-trained athletes have high oxidative capacity, enhanced insulin sensitivity, and high intracellular lipid accumulation in muscle. These characteristics are likely due to altered gene expression levels in muscle. We used microarrays to detect gene expression profile in endurance-trained athlete skeletal muscle.

Chronic restraint stress increases transcriptomic indicators of biological aging in mouse bone marrow leukocytes

Project description:Genome-wide transcriptional profiling results were used to examine the effect of a psychological stress paradigm for rodents (chronic restraint) on indicies of biological aging in murine femoral bone marrow leukocytes and to assess the extent to which propranolol could block such effects.

RNA-sequencing and bioinformatics analysis of long non-coding RNAs and mRNAs in the prefrontal cortex of mice following repeated social defeat stress

Project description:RNA-sequencing was used to screen all differentially expressed (DE) lncRNAs and mRNAs between the RSD and control groups. In mice experiencing RSD, 373 and 454 lncRNAs, along with 1142 and 654 mRNAs were significantly upregulated and downregulated, respectively.Available informatics evidence highlighted the likely role of synapse dysfunction and abnormal synaptic neurotransmission in these behaviors. Thus, our findings provide potential candidate biomarkers or intervention targets for chronic psychological stress-induced neuropsychiatric disorders.

Genomic Counter-Stress Changes Induced by Mind-Body Practice

Project description:Mind-body practices that elicit the relaxation response (RR) have been used worldwide for millennia to prevent and treat disease. The RR is believed to be the counterpart to stress response and is characterized by decreased oxygen consumption, increased exhaled nitric oxide, and reduced psychological distress. Individuals experiencing chronic psychological stress have the opposite pattern of physiology and a characteristic transcriptional profile. We hypothesized that consistent, long-term practice of RR techniques results in characteristic changes in gene expression. We tested this hypothesis by assessing the transcriptional profile of whole blood in healthy, long-term practitioners of daily RR practice (group M) in comparison to healthy controls (group N1). The signature obtained has been validated on new subject data. Experiment Overall Design: In the study, the gene expression profiling was performed on individuals with a long-term RR practice (group M; n=19) or those with no prior RR experience; novice (group N1; n=19). Group N1 novices, furthermore, underwent 8-weeks of RR training (Group N2; n=20) for the prospective analysis.As a validation of results , we developed an independent validation sets that includes gene expression profiling on 4 N1, 4 N2 and 6 M subjects.

Molecular mechanisms of cannabinoid type II receptor agonists in a mouse model of psychological stress-induced cardiac injury revealed by whole transcriptomic analysis

Project description:To investigate the mechanisms of chronic psychological stress-induced cardiac injury and the protective mechanisms of cannabinoid type II agonists in a model of psychological stress-induced cardiac injury We constructed a mouse chronic psychological stress model based on a chronic unpredictable stress pattern. Mice were randomly divided into control, case (psychological stress group), and treatment groups (post-stress with the cannabinoid type II receptor agonist JWH133) to begin a 3-week psychological stress procedure, and cardiac tissue was subsequently removed for whole-transcriptome sequencing

Gene expression data from C.elegans

Project description:Numerous studies have shown that resistance to oxidative stress is crucial to stay healthy and to reduce the adverse effects of aging. Accordingly, nutritional interventions using antioxidant food-grade compounds or food products are currently an interesting option to help improve health and quality of life in the elderly. Live lactic acid bacteria (LAB) administered in food, such as probiotics, may be good antioxidant candidates. Nevertheless, information about LAB-induced oxidative stress protection is scarce. To identify and characterize new potential antioxidant probiotic strains, we have developed a new functional screening method using the nematode Caenorhabditis elegans as host. C. elegans were fed on different LAB strains (78 in total) and nematode viability was assessed after oxidative stress (3mM and 5mM H2O2). One strain, identified as Lactobacillus rhamnosus CNCM I-3690, protected worms by increasing their viability by 30% and, also, increased average worm lifespan by 20%. We performed a transcriptomic analysis of C. elegans fed with this strain and showed that increased lifespan is correlated with differential expression of the DAF-16/insulin-like pathway, which is highly conserved in humans. Gene expression in C. elegans wild-type strain (N2) was analyzed in worm populations fed with E. coli OP50 (control condition) or the corresponding LAB (Lactobacillus rhamnosus CNCM I-3690 or Lactobacillus rhamnosus CNCM I-4317) . Three days and ten days feeding period was analyzed.
