Project description:To predict Rp58-regulated gene involved in myogenesis, RNA profiling experiments were performed, comparing RNA derived from C2C12 with or without expressing shRNA for Rp58. As a result, 271 genes were upregulated in C2C12 stably expressing shRNA-Rp58 cells compared with control C2C12 cells. As Rp58 is repressor in C2C12, we hypothesized that Rp58 regulates gene cluster which expression is downregulated in accordance with Rp58 expression and myogenesis progression. In this regard, we also characterized dynamic gene expression patterns during myogenesis by microarray at 4 different stage (GM, day 0, 2, 4) of C2C12 myogenesis assays and found that 399 genes expression is characterized as downregulation pattern during myogenesis. Importantly, this down regulation gene set and upregulated genes by shRNA for Rp58 were highly overlapped. Keywords: time course, shRNA

Project description:Tamoxifen, a selective estrogen receptor modulator (SERM), is commonly used in the treatment of hormone-responsive cancers. The effects of tamoxifen in anabolic tissues harboring estrogen-receptors, such as skeletal muscle, are poorly understood. As estrogen and estrogen receptors play an important role in skeletal muscle development and repair, we hypothesize that tamoxifen may have specific effects on myogenesis, the developmental process underlying muscle cells differentiation and repair. Myogenesis is characterized by fine-tuned changes in protein expression as embryonic myoblasts and adult satellite cells transition from pluripotent stem cells to multinucleated, contractile muscle fibers: we undertake a quantitative proteomic analysis of tamoxifen-induced changes in developing skeletal muscle cells which we expect may also shed light on the effect of tamoxifen on muscle repair.
We report a tandem mass-tag (TMT) approach to tamoxifen-treated myogenesis in C2C12 cells, a well-characterized model of in vitro murine skeletal muscle differentiation. A longitudinal analysis of >10,000 proteins identified in C2C12 myogenesis revealed a novel subset of 1,239 myogenically-regulated proteins. This set of regulatory proteins clustered into five distinct longitudinal expression trends which significantly overlap those obtained in similar analyses performed in human myocytes. A longitudinal analysis of myogenesis in the presence of tamoxifen, when contrasted with a similar analysis in untreated myogenesis finds that while the vast majority of myogenically-regulated proteins were unaffected by tamoxifen treatment, specific pathways and networks are affected. We document a specific functional enrichment for adiponectin-signaling, whereby a set of 198 proteins were differentially expressed relative to controls at one or more stages of myogenesis, the majority of which were involved in steroid biosynthesis, lipid storage and/or metal ion homeostasis. Interestingly, the only protein that was differentially expressed in the tamoxifen-treated cells at every stage of myogenesis was metallothionein-1 (MT1). Elevated levels of MT1 have been correlated with tamoxifen resistance and increased patient mortality and relapse in breast cancer, as well as with cachexia and muscle atrophy in rodent models. Increased MT1 expression levels may contribute to the musculoskeletal effects reported by patients undergoing tamoxifen treatment. Finally, we present a powerful, self-validating pipeline for analyzing the total proteomic response to in vitro treatment across every stage of muscle cells development which can be easily adapted to study the effects of other drugs on myogenesis.

Cells were harvest at different stages during myogenesis including proliferating, confluence, 1 day post-differentiation induction, 2 day post-differentiation induction and 4 days post-differentiation induction. Keywords: time course This experiment was a reference design miRNA microarray where all time points were compared to a pooled proliferating C2C12 sample, made up of 4 proliferating biological replicates. Each time point had four bioloigcal replicates of which two were labelled with Cy3 and two were labelled with Cy5.

Importantly, this down regulation gene set and upregulated genes by shRNA for Rp58 were highly overlapped. Experiment Overall Design: C2C12 murine skeletal muscle cells were purchased from American Type Experiment Overall Design: culture Collection (ATCC). These cells were mainteined in GM (DMEM Experiment Overall Design: supplemented with 10% FBS). Cells were grown in GM and after reaching Experiment Overall Design: counfluence, the medium was switched to DM (DMEM supplemented with 2% hourse serum) and further incubated. The medium was changed every 2 days. Culture was performed by using within five passages cells. For the experiment of shRNA for Rp58, transfection was performed by using Lipofectamin 2000 (Invitrogen). Stable transfectants were obtained by selection of the transfected C2C12 cells for two weeks. Experiment Overall Design: Microarray analysis - RNA was isolated as described from C2C12, and cRNA was synthesized. 10 ug of cRNA were hybridized to Affymetrix mouse 430 2.0 arrays. Intensity values were quantified using RMA algorithm. Experiment Overall Design: MAPPFinder (www.genmapp.org) was used to integrate expression data with known pathways.

Project description:Myogenesis is governed by signalling networks whose regulations are tightly controlled in a time-dependent manner. While different protein kinases have been identified to regulate various aspects of myogenesis, knowledge on the global signalling networks and their downstream substrates during myogenesis remains incomplete. Here, we map the myogenic differentiation of C2C12 cells using mass spectrometry (MS)-based phosphoproteomics and proteomics. From these data, we infer global kinase activity and predict substrates of key kinases that are involved in myogenesis. We found that multiple mitogen-activated protein kinases (MAPKs) mark the initial wave of signalling cascades. Further phosphoproteomic and proteomic profiling with MAPK1/3 and MAPK8/9 specific inhibitions unveil their shared and distinctive roles on myogenesis.

Project description:Adipocytes are key players in maintaining energy homeostasis and are classified into two different categories: white and brown adipocyte. While white adipocytes store energy as triacylglycerols in lipid droplets, brown adipocytes combust excess chemical energy and release in the form of heat through uncoupled respiration. This characteristic phenomenon of brown fat attracts researchers and pharmacological industries to view brown fat as one of the potential therapeutic targets for obesity and associated metabolic disease. In the current study, we investigated the effect of a small molecule, sesaminol (SML) on brown fat activity and found that SML induces thermogenic program in primary white adipocytes as well as chow diet fed mice. In particular, SML treatment to mice elevated mitochondrial complex proteins and the rate oxygen consumption in brown and white fat. Administration of SML to high fat diet (HFD) challenged mice decreased weight gain, adiposity and cholesterol levels along with an increase of brown fat gene program in brown and white fat. Mechanistically, SML repressed the myogenic gene program in C2C12 myoblasts and increased all mitochondrial marker genes as appeared in brown adipose cells. Together, our results demonstrate that SML stimulates brown adipose function and protects mice against diet induced weight gain.

Project description:C2C12 is a myoblast cell line usually used for study of muscle differentiation. Myod1 is a pro-differentiation factor for myogenesis. We found that CRISPR/Cas9-mediated Myod1 gene knockout in C2C12 cells led to the loss of myoblast identity and gain of neural properties.
