(Submitter supplied) 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. more...

(Submitter supplied) Regular physical exercise evokes profound physiological responses which are strongly associated with many health benefits. However, the details of cellular networks and mechanisms underlying the adaptive responses to exercise remain to be elucidated. We have previously shown the usefulness of electrical pulse stimulation (EPS) to investigate metabolic effects of exercise in cultured human myotubes. The aim of the present study was to uncover networks of signaling pathways and regulatory molecules responsible for the metabolic effects of exercise in human skeletal muscle cells exposed to chronic EPS. Differentiated myotubes were subjected to two different EPS protocols (protocol 1; 2 ms, 10 V, 0.1 Hz for 24 h or protocol 2; 2 ms, 30 V, and 1 Hz for 48 h). Fuel handling was assessed using radiolabeled substrates. The transcriptome, cell proteome, and secreted proteins from EPS-treated and untreated myotubes were analyzed using a combination of high-throughput RNA sequencing, microarray, and high-resolution liquid chromatography mass spectrometry. Independent validation of selected putative myokines were measured using ELISA or multiplex assay. Oxidative metabolism was enhanced in human myotubes exposed to EPS protocol 1. A total of 81 differentially regulated proteins and 952 differentially expressed genes (DEGs) were observed in the cells after EPS protocol 1. Gene ontology (GO) analysis indicated that significantly regulated proteins and genes were enriched in biological processes related to glycolytic pathways, positive regulation of fatty acid oxidation, and oxidative phosphorylation, as well as muscle contraction, autophagy/mitophagy, and oxidative stress. Moreover, proteomic identification of secreted proteins revealed extracellular levels of 137 proteins were changed in myotubes subjected to EPS protocol 1. We also found some degree of overlap between the DEGs found in myotubes submitted to EPS protocol 1 and protocol 2. Among these DEGs was a myokine, leukemia inhibitory factor, which showed to enhance the glucose uptake in skeletal muscle cells, indicating autocrine mechanism to maintain metabolic homeostasis. Collectively, our data provides new insight into the transcriptome, proteome and secreted proteins alterations following in vitro exercise and is a valuable resource for understanding the molecular mechanisms and regulatory molecules mediating the beneficial metabolic effects of exercise.

(Submitter supplied) The role of peroxisome proliferator-activated receptor δ (PPARδ) activation on global gene expression and mitochondrial fuel utilization were investigated in human myotubes. Only 21 genes were up-regulated and 3 genes were down-regulated after activation by the PPARδ agonist GW501516. Pathway analysis showed up-regulated mitochondrial fatty acid oxidation, TCA cycle and cholesterol biosynthesis. GW501516 increased oleic acid oxidation and mitochondrial oxidative capacity by 2-fold. more...

(Submitter supplied) 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. more...

(Submitter supplied) Secreted microRNAs (miRNAs) enclosed within extracellular vesicles (EVs) play a pivotal role in intercellular communication by regulating recipient cell gene expression and affecting target cell function. Here, we report the isolation of three distinct EV subtypes from the human colon carcinoma cell line LIM1863--shed microvesicles (sMVs) and two exosome populations (immunoaffinity isolated A33-exosomes and EpCAM-exosomes). more...

(Submitter supplied) The role of extracellular vesicles (EVs), specifically exosomes, in intercellular communication likely plays a key role in placental orchestration of pregnancy and maternal immune sensing of the fetus. While murine models are powerful tools to study pregnancy and maternal-fetal immune interactions, in contrast to human placental exosomes, the content of murine placental and pregnancy exosomes remains largely understudied. more...
