Novel Transcriptomic Network Dynamics in Response to Divergent Acute Exercise Challenges in Young Adults

ABSTRACT: This study measured the transcriptome-wide response in skeletal muscle and circulating extracellular vesicles (EVs) in young adults randomized to a single exposure of TRAD (n=21, 12M/9F, 22±3y) or HITT (n=19, 11M/8F, 22±2y) exercise. Next-generation sequencing captured small (<200nt), long (>200nt), and circular RNA species in muscle and EVs. In parallel, data streams were analyzed to identify transcripts differentially expressed (|log2FC|>1, FDR≤0.05) immediately (h0, EVs only), h3, and h24 postexercise within and between exercise doses. Strongly-trending responsive transcripts (FDR<0.2) underwent singular value decomposition to summarize the data structure into latent variables, LVs) deconvolving inter-regulatory relationships across transcripts; LVs were compared across time and exercise dose.

Effects of Voluntary Running Wheel Exercise-induced Extracellular Vesicles on Anxiety

Project description:Exercise induces the release of extracellular vesicles (EVs) into the circulation, which transmit signals between organs. EVs contain microRNAs (miRNAs) that inhibit mRNA translation or enhance mRNA degradation. However, the effects of exercise-induced EVs on anxiety remain poorly understood. We used microarrays to figure out the global alteration of gene expression in the hippocampus underlying stress and sedentary or exercise-induced EVs.

A ribosomal protein homolog modulates gene expression and virulence in a bacterial pathogen

Project description:To assess which F. tularensis LVS transcripts are impacted by loss of bS21-2, we generated cells lacking the gene encoding bS21-2 (LVS ∆rpsU2). We then grew wild-type cells containing an empty vector (LVS pF), cells lacking bS21-2 with empty vector (LVS ∆rpsU2 pF), and cells lacking the native bS21-2 but ectopically expressing bS21-2 from a plasmid (LVS ∆rpsU2 pF-rpsU2-V). We isolated RNA from mid-log phase cells and analyzed by RNA-Seq.

Distinct microRNA and protein profiles of extracellular vesicles secreted from myotubes from morbidly obese donors with type 2 diabetes in response to electrical pulse stimulation [EPS_MV]

Project description:We have used a combined transcriptome-proteome approach to describe how EPS affected the cargo of extracellular vesicles derived from myotubes from morbidly obese patients with T2D, and revealed several new factors, both miRs and proteins, that might act as exercise factors. During exercise, skeletal muscles release signaling factors that communicate with other organs and mediate beneficial effects of exercise. These factors include myokines, metabolites, and extracellular vesicles (EVs). In the present study, we have examined how electrical pulse stimulation (EPS) of myotubes, a model of exercise, affects the cargo of released EVs. Chronic low frequency EPS was applied for 24 h to human myotubes isolated and differentiated from biopsy samples from 6 morbidly obese females with T2D, and EVs, both exosomes and microvesicles (MV), were isolated from cell media 24 h thereafter.Protein content was assessed by high-resolution proteomic analysis (LC-MS/MS), non-coding RNA was quantified by Affymetrix GeneChip Multispecies miRNA-4_0 Array and Flash Tag TM Biotin RNA labelling, Thermo Fisher), and selected microRNAs (miRs) validated by real time RT-qPCR. We found that human myotubes secrete both exosomes and MV. EPS treatment of the myotubes, clearly changed the protein content of both exosomes and MV, whereas the miR content was changed only in exosomes. We suggest that skeletal muscle derived EVs can contribute to circulatory EVs and mediate beneficial effects of exercise in metabolically active organs.

Extracellular Vesicle miR-1 Delivery from Skeletal Muscle to Adipose Tissue Modifies Lipolytic Pathways in Response to Resistance Exercise in Humans

Project description:Extracellular vesicles (EVs) have emerged as important mediators of inter-tissue signaling and exercise adaptations. In this human study (n=32), muscle-specific microRNA-1 (miR-1) was delivered to adipose tissue via EVs following an acute bout of resistance exercise. Using a multi-model machine learning automation tool, we discovered muscle primary miR-1 transcript and CD63+ EV count in circulation as top explanatory features for changes in adipose miR-1 levels in response to resistance exercise. RNA-sequencing (RNA-seq) and in-silico prediction of miR-1 target genes identified CAV2 and TRIM6 as miR-1 target genes upregulated in adipose tissue of participants with high increases in miR-1 levels following resistance exercise. Overexpression of miR-1 in differentiated human adipocyte-derived stem cells downregulated these miR-1 targets and enhanced catecholamine-induced lipolysis. These data identify a novel mechanism by which skeletal muscle communicates to adipose tissue and modulates lipolysis via delivery of miR-1-containing EVs.

Differential microRNA profiles of intramuscular and secreted extracellular vesicles in human tissue-engineered muscle

Project description:Exercise affects the expression of microRNAs (miR/s) and muscle-derived extracellular vesicles (EVs). To evaluate sarcoplasmic and secreted miR expression in human skeletal muscle in response to exercise-mimetic contractile activity, we utilized a three-dimensional tissue-engineered model of human skeletal muscle (“myobundles”). Myobundles were subjected to three culture conditions: no electrical stimulation (CTL), chronic low frequency stimulation (CLFS), or intermittent high frequency stimulation (IHFS) for 7 days. RNA was isolated from myobundles and from extracellular vesicles (EVs) secreted by myobundles into culture media; miR abundance was analyzed by miRNA-sequencing. We used edgeR and a within-sample design to evaluate differential miR expression and Pearson correlation to evaluate correlations between myobundle and EV populations within treatments with statistical significance set at p<0.05. Numerous miRs were differentially expressed between myobundles and EVs; 116 miRs were differentially expressed within CTL, 3 within CLFS, and 2 within IHFS. Additionally, 25 miRs were significantly correlated (18 in CTL, 5 in CLFS, 2 in IHFS) between myobundles and EVs. Electrical stimulation resulted in differential expression of 8 miRs in myobundles and only 1 miR in EVs. Several KEGG pathways, known to play a role in regulation of skeletal muscle, were enriched, with differentially overrepresented miRs between myobundle and EV populations identified using miEAA. Together, these results demonstrate that in vitro exercise-mimetic contractile activity of human engineered muscle affects both their expression of miRs and number of secreted EVs. These results also identify novel miRs of interest for future studies of the role of exercise in organ-organ interactions in vivo
