Transcription profiling by array of the secretome from human myotube and myotube derived vesicles

ABSTRACT: Human satellite cells were isolated from muscle biopsies and expanded in vitro. Cells were induced to differentiate into branched multinucleated myotubes by serum depletion and were harvested from three independent cultures after 72 hours. Total RNA was isolated, amplified, labelled and hybridised to Illumina Human WG-6v3 arrays. Data were analysed to identify a "virtual secretome". These data and proteomic data from similar cultures suggested that differentiating muscle cultures produce microvesicles - which were characterised in the ensuing experiment. Human satellite cells were cultured as before (duplicate cultures) and culture supernatants were subjected to a differential centrifugation procedure, resulting in isolation of two distinct vesicle populations: exosomes and microparticles. Total RNA was isolated from these vesicle populations and the cells from which they were derived. RNA was amplified, labelled and hybridised to Illumina Human HT12v3 arrays. Data from myotubes, exosomes and microparticles were analysed to identify transcripts present, differential expression and functional interpretation of transcriptomes. IDAT files are available on the ArrayExpress ftp site in the additional.zip file.

Modeling OPMD in myotube cultures reveals reduced accumulation of soluble mutant PABPN1 protein

Project description:Oculopharyngeal muscular dystrophy (OPMD) is an autosomal dominant disease caused by an alanine tract expansion mutation in Poly(A)-binding protein nuclear 1 (expPABPN1). To model OPMD in a myogenic and physiological context, we generated mouse myoblast cell clones stably expressing either human wild type (WT) or expPABPN1 at low levels. The transgene expression is induced upon myotube differentiation and results in formation of insoluble nuclear PABPN1 aggregates that are similar to the in vivo aggregates. Quantitative analysis of PABPN1 protein in myotube cultures revealed that expPABPN1 accumulation and aggregation is greater than that of the WT protein. In a comparative study we found that aggregation of expPABPN1 is more affected by inhibition of proteasome activity, as compared with the WT PABPN1 aggregation. Consistent with this, in myotubes cultures expressing expPABPN1 deregulation of the proteasome was identified as the most significantly deregulated pathway. Differences in the accumulation of soluble WT and expPABPN1 were consistent with differences in ubiquitination and protein turnover. This study indicates, for the first time, that in myotubes the ratio of soluble to insoluble expPABPN1 is significantly lower compared to that of the WT protein. We suggest that this difference can contribute to muscle weakness in OPMD. Clones on IM2 mouse myotubes that stably express Ala10-PABPN1-FLAG (WTA, WTD) or Ala17-PABPN1-FLAG (D7E). The transgene expression level in D7E and WTA are similar. WTA and WTD reflects differences in expression levels. RNA was extracted from myotubes of WTA, WTD and D7E in triplicates. cDNA synthesis and lebeling was preformed with the Illumina cDNA labeling kit.

Exosomes derived from pancreatic cancer cells induce insulin resistance in C2C12 myotube cells through the PI3K/Akt/FoxO1 pathway

Project description:Prospective epidemiological studies have consistently supported that pancreatic cancer associated new-onset diabetes mellitus (PC-DM) is probably an important clue for early diagnosis of pancreatic cancer (PC). However, the mechanism underlying remains fragmentary. In this study, two types of exosomes released by murine pancreatic cancer cells and murine pancreatic ductal epithelial cells were isolated，and their effects on skeletal muscle cells were invested. The results showed that PC-derived exosomes can readily enter C2C12 myotubes, and then induce lipidosis, glucose intake inhibition. We also found that PC-derived exosomes can inhibit Insulin and PI3K/Akt signaling, in which insulin-induced FoxO1 nuclear exclusion is preserved while Glut4 trafficking is impaired. In addition, further microarray and Kyoto encyclopedia of genes and genomes (KEGG) analysis prompted that exosomal microRNAs (miRNAs) probably play an critical role in this process, which also has been preliminarily demonstrated in vitro. Taking together, these results suggest that PC-derived exosomes induce insulin resistance (IR) of skeletal muscle cells through Insulin and PI3K/Akt/FoxO1 signaling pathway, and exosomal miRNAs are probably involved. The novel findings also support the theories of cancer “metabolic reprogramming” and “metabolic crosstalk”.

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.
