Remodeling of the human skeletal muscle proteome found after long-term endurance training but not after strength training

ABSTRACT: Proteomic characterization of skeletal muscle biopsies collected from the vastus lateralis of 44 male and female human subjects. Research subjects were divided in three different groups based on their individual exercise backgrounds and physical performance testing: 1) endurance trained (males; ME, n = 9 and females; FE, n = 9, with at least 15 years’ of regular training experience), 2) strength-trained males (MS, n = 9, with at least 15 years’ of regular training experience), and 3) age-matched healthy untrained controls (males, MC, n = 9 and females FC, n = 8, with a self-reported history of <2 exercise bouts per week over the past 15 years).

Exercise training has tremendous systemic tissue-specific health benefits, but the molecular adaptations to long-term exercise training are not completely understood. We investigated the skeletal muscle proteome of highly endurance-trained, strength-trained, and untrained individuals and performed exercise- and sex-specific analyses. Of the 6,000+ proteins identified, >650 were differentially expressed in endurance-trained individuals compared with controls. Strikingly, 92% of the shared protein ...[more]

Aplysia Pleural Ganglia 24 Hours After Long-Term Habituation Training

Project description:We used a custom-designed microarray and qPCR to characterize the persistent transcriptional response to long-term habituation training in the marine mollusk Aplysia californica. Aplysia were exposed to either 3 days of spaced long-term habituation training (10 rounds of stimulation/day; each round = 15 min brushing at a 10s ISI; 15 min rest between rounds); a matched set of controls was not exposed to any brushing (n = 8/group). While reflex responsiveness remained stable in controls, trained animals exhibited a large reduction in siphon-withdrawal duration that was evident at stimulation sites across the entire dorsal surface of the body (head, tail, and siphon). This habituation was retained for at least 24 hours after the end of training. Immediately after 24 hour retention tests, pleural ganglia were harvested from each trained animal and its matched control. The pleural ganglia contain the VC nociceptors, which we confirmed are activated by the brush stimulus used to produce habituation. Microarray analysis from 8 biological replicates suggests that long-term habituation training persistently regulates 21 transcripts. We used qPCR to test a subset of these transcripts and found persistent regulation of an putative Aplysia cornichon homolog. Between-subjects comparison of a trained animal to a matched control (matching based on duration of pre-test responsiveness). Conducted with 8 biological replicates, meaning 8 arrays, each comparing 1 trained and 1 matched control.

Aplysia pleural Ganglia 1 Hour After Long-Term Sensitization Training

Project description:We used a custom-designed microarray and qPCR to characterize the rapid transcriptional response to long-term sensitization training in the marine mollusk Aplysia californica. Aplysia were exposed to repeated noxious shocks to one side of the body (4 ten-second shocks at 90mA, 30 min ISI), a procedure known to induce a transcription-dependent and long-lasting increase in reflex responsiveness that is restricted to the side of training. One hour after training, pleural ganglia from the trained and untrained sides of the body were harvested; these ganglia contain the sensory nociceptors which help mediate the expression of long-term sensitization memory. Â Microarray analysis from 8 biological replicates suggests that long-term sensitization training rapidly regulates at least 102 transcripts. We used qPCR to test a subset of these transcripts and found that 86% were confirmed in the same samples, and 83% of these were again confirmed in an independent sample (n = 9 animals). Thus, our new microarray design shows very strong convergent and predictive validity for analyzing the transcriptional correlates of memory in Aplysia. Fully validated transcripts include some previously identified as regulated in this paradigm (ApC/EBP and ApEgr) but also include novel findings. Specifically, we show that long-term sensitization training rapidly up-regulates the expression of transcripts which encode a C/EBP gamma, a glycine transporter, and a vacuolar-protein-sorting-associated protein. Within-subjects comparison of trained (Cy5) to untrained (Cy3) pleural ganglia with 8 biological replicates. Each replicate is a trained sample from two animals (right and left trained) and each untrained sample is from the same two aniamls (right and left untrained)

Exosomal miRNA profile of physical activity as preventive lifestyle intervention

Project description:Emerging evidence suggests that circulating exosomes mediate some of the beneficial effects of exercise via the transfer of microRNAs between tissues. However, the impact of short-term (0.5 year in this study) and long-term (25+ years in this study) regular bouts of exercise on circulating exosomal microRNAs (exomiRs) remains unknown. Our aim was to elucidate the prevention pattern of exomiRs and their targeted pathways. Therefore, in the present study we analyzed serum exomiR expression in healthy young, sedentary participants (n=14) at baseline and following a half year-long moderate-intensity regular exercise training. We also analyzed serum exomiR expression in older, healthy trained participants (seniors, n=11) who engaged in endurance activities for at least 25 years. Following the isolation and enrichment of serum exosomes their exomiR levels were determined using the amplification-free Nanostring platform.

Contractile activity-specific transcriptome response to acute endurance exercise and training in human skeletal muscle

Project description:In our study, we investigated for contractile activity-specific changes in the transcriptome in untrained and trained (after an aerobic training programme) human skeletal muscle. The second goal was to examine effect of aerobic training on gene expression in muscle at baseline (after long term training). Seven untrained males performed the one-legged knee extension exercise (for 60 min) with the same relative intensity before and after a 2 month aerobic training programme (1 h/day, 5/week). Biopsy samples were taken at rest (baseline condition, 48 h after exercise), 1 and 4 h after the one-legged exercise from m. vastus lateralis of either leg. Comparison of gene expression in exercised leg with that in non-exercised [control] leg allowed us to identify contractile activity-specific genes in both untrained and trained skeletal muscle, i.e., genes that play a key role in adapting to acute exercise, regardless of the level of fitness. RNA-sequencing (84 samples in total; ~47 million reads/sample) was performed by NextSeq 500 and HiSeq 2500 (Illumina). Two months aerobic training increased the aerobic capacity of the knee-extensor muscles (power at anaerobic threshold in the incremental one-legged and cycling tests), the maximum rate of ADP-stimulated mitochondrial respiration in permeabilized muscle fibres and amounts of oxidative phosphorylation proteins. Contractile activity-specific changes in the transcriptome in untrained and trained human skeletal muscle were revealed for the first time. After 2 month aerobic training, transcriptome responses specific for contractile activity in trained muscle substantially decreased relative to those in untrained muscle. We found out that adaptation of skeletal muscle to regular exercise is associated not only with a transient change in the transcriptome after each stress (acute exercise), but also with a marked change in baseline expression of many genes after repeated stress (e.g., long term training).

Zebrafish were subjected to swim-training from 5 days post fertilization (dpf) until 10 dpf. Subsequently, we performed a genome-wide microarray analysis on the caudal fins of control and trained fish at 10 dpf. The goal of the project was to investigate the effects of swim-training on the gene expression level during caudal fin development in zebrafish larvae. Two-condition experiment: control vs trained fish. RNA was isolated from pooled caudal fins of 15 control fish (in duplo: pooled control samples (C2 and C3)) and of 15 trained fish (in duplo: pooled trained samples( T2 and T3)). Subsequently, each pooled RNA sample of control and trained caudal fins was labeled with Cy3 and Cy5 in order to correct for dye bias. We included a technical replicate of the labeled C2 and T2 samples.

Investigating the target and off-target landscape of PLK1 small molecule inhibitor volasertib

Project description:In this study we aimed to identify off-targets of polo-like kinase 1 (Plk1) small molecule inhibitor volasertib. Plk1 is an important cell cycle kinase and an attractive target for anticancer treatment. Volasertib is ATP-competitive small molecules that may also block the ATP-pocket of other proteins. Despite the fatal infections and negative survival in a phase III trial on volasertib in acute myeloid leukemia volasertib has been a promising treatment option in children with rhabdomyosarcoma. Therefore, there is a need to understand the nature of adverse effects that possibly originate from the off-target proteins. We used thermal proteome profiling (TPP) to identify proteins that have a change in the thermal stability after treatment with volasertib. The temperature of aggregation of several proteins involved in prostaglandin and phosphatidyl-inositol phosphate metabolism increased after treatment with volasertib. PIP4K2A and ZADH2 were stabilized both by treatment in living cells and cell lysate. Functional disruption of these proteins affects the immune response and fatty acid metabolism. In addition, volasertib was found to affect transcriptional coactivators, normal and alternative RNA splicing regulators and proteins involved in the intracellular transport regulation. Our data suggests that the identified proteins may contribute more to the understanding of anti-tumor effect of volasertib.

Candida albicans induces monocyte training via epigenetic programming through a dectin 1-dependent pathway

Project description:Non-specific protective effects against reinfection have been described following infection with Candida albicans. Here we show that mice defective in functional T and B lymphocytes were protected against reinfection with C. albicans in a monocyte-dependent manner. C. albicans and beta glucans induced functional programming of monocytes, leading to enhanced cytokine production in vivo and in vitro. The training required the beta glucan receptor dectin 1 and the non-canonical Raf 1 pathway. Monocyte training by beta-glucans was mediated by epigenetic mechanisms through genome-wide changes in histone trimethylation at H3K4. Pathway analysis showed specific induction of epigenetic changes in genes of innate immunity. The functional programming of monocytes, reminiscent of similar properties of NK cells, has been termed M-bM-^@M-^\trained immunityM-bM-^@M-^] and may be employed for the design of improved vaccination strategies. Chromatin-IP at day7 followed by highthroughput sequencing to look at the differences in H3K4me3 and H3K27me3 binding in Monocytes either cultured in RPMI only versus those trained for 24hrs with beta glucan. Additionally expression analysis was performed by doing strandspecific RNAseq also for both unstimulated and beta glucan trained monocytes for correlating the histone modification changes with the expression changes. Biological replicates were generated from independent samples for H3K4me3 and RNAseq. Additional H3K4me3 ChIP-seq assays were performed for day0 untreated, 24hrs control and beta glucan trained monocytes. H3K4me3 ChIP-seq was also performed for Mouse macrophages both saline(control) and low dose Candida treated.
