Gene expression in primary isolated human myoblast during proliferation, G0 arrest, reactivation and differentiation

ABSTRACT: A microarray study including two primary isolated human myoblast cell cultures ( samples A and B) was designed in order to detect the differences in global gene expression during four different culture conditions, two actively proliferating and two non-proliferating. Myoblasts were kept long term proliferating (BG0, before G0) followed by G0 arrest (G0), reactivation (AG0, after G0) and finally they were differentiated (Dif). The samples BG0 and AG0 were harvested when cells reached 70-80% confluence. The raw data from gene arrays were normalized, sample A and B were paired and the mean expression value used for further analyses. The four samples were compared to each other in order to detect differences in gene expression between the samples. Primary isolated human myoblast cells were cultured through four different culture, BG0, G0, AG0 and Dif. Two independent studies were made with primary isolated myoblasts from two different individuals for each of the four culture condition. Thus the number of samples for microarray analyses was 8.

Novel RNA-binding activity of MYF5 enhances Ccnd1/Cyclin D1 mRNA translation during myogenesis

Project description:Skeletal muscle contains long multinucleated and contractile structures known as muscle fibers, which arise from the fusion of myoblasts into nucleated myotubes during myogenesis. The myogenic regulatory factor (MRF) MYF5 is the earliest to be expressed during myogenesis and functions as a transcription factor in muscle progenitor cells (satellite cells) and myocytes. In mouse C2C12 myocytes, MYF5 is implicated in the initial steps of myoblast differentiation into myotubes. Ribonucleoprotein immunoprecipitation (RIP) analysis showed that MYF5 bound a subset of myoblast mRNAs; prominent among them was Ccnd1 mRNA, which encodes the key cell cycle regulator CCND1 (Cyclin D1). Biotin-RNA pulldown, UV-crosslinking, and gel shift experiments indicated that MYF5 was capable of binding the 3' untranslated region (UTR) and the coding region (CR) of Ccnd1 mRNA. MYF5 silencing in proliferating growing myoblasts revealed that and MYF5 promoted CCND1 translation, and it also modestly increased transcription of Ccnd1 mRNA. Importantly, silencing MYF5 reduced myoblast growth as well as differentiation of myoblasts into myotubes, while overexpressing MYF5 in C2C12 cells upregulated CCND1 expression. We propose that MYF5 enhances early myogenesis in part by coordinately elevating Ccnd1 transcription and Ccnd1 mRNA translation. Four replicates were utilized from either Control (IgG) or MYF5-immunoprecipitated RNA samples from C2C12 cells growing in either growth medium (GM) or differentiation medium (DM) for a total of sixteen samples.

Baf250A, Brd9 and Baf180 knockdown impact on myoblast transcriptome

Project description:We performed RNA-seq to investigate global changes in gene expression in proliferating myoblasts transduced with either the scramble, Baf250A, Brd9 or Baf180 shRNAs. This study revelaed that the Baf250-containing BAF complex and the Brd9-containing ncBAF complex contribute to myoblast proliferation but the Baf180-containing PBAF subfamily does not.

Skeletal muscle myoblasts: GATA4-Wt, -KO, -OE; day 0, 3

Project description:Gene expression in satellite cell-derived primary myoblasts islolated from Gata4-loxP mice. Myoblasts were infected with nLacZ for control (Wt), Cre recombinase to knockout GATA4 (KO), or GATA4 expression vector to overexpress GATA4 (OE). Infected myoblasts were cultured in growth medium (day 0) then differentiated into myotubes in differentiation medium for 3 days (day 3). Total 18 samples. Three replicates in each myoblast; GATA4-Wt, -KO, and -OE myoblasts at day 0 and day 3.

ChIP-seq of GATA4 in mouse skeletal muscle myoblasts

Project description:GATA4 occupancy on the mouse genome of satellite cell-derived primary myoblasts. Proliferating myoblasts cultured in growth medium were immunoprecipitated with anti-GATA4 antibody or control IgG. Precipitated genomic DNAs were subjected to next generation sequencing. Paired-end 150 bp sequence reads of GATA4-ChIP and IgG-ChIP using mouse skeletal muscle myoblasts.

Asymmetric cancer cell division regulated by AKT, Reactive Oxygen Species (ROS) high versus ROS low mRNA

Project description:Human tumors often contain slowly proliferating cancer cells that resist treatment but we do not know precisely how these cells arise. We show that rapidly proliferating cancer cells can divide asymmetrically to produce slowly proliferating “G0-like” progeny that are enriched following chemotherapy in breast cancer patients. Asymmetric cancer cell division results from asymmetric suppression of AKT/PKB kinase signaling in one daughter cell during telophase of mitosis. Moreover, inhibition of AKT signaling with small molecule drugs can induce asymmetric cancer cell division and the production of slow proliferators. Cancer cells therefore appear to continuously flux between symmetric and asymmetric division depending on the precise state of their AKT signaling network. This model may have significant implications for understanding how tumors grow, evade treatment, and recur. 3 replicates each of MCF7 Reactive Oxygen Species (ROS) high, HCT116 ROS high, MCF7 ROS low, and HCT116 ROS low.

Distinct transcriptional networks in quiescent myoblasts: a role for Wnt signaling in reversible vs irreversible arrest

Project description:Using cDNA arrays, we compared G0 myoblasts (S48) with post-mitotic myotubes. Our findings define the transcriptional program of quiescent myoblasts in culture which show important similarities with muscle satellite cells, and establish that distinct gene expression profiles characterize irreversible and reversible arrest Cell were synchronized in G0 by resuspending them in semi-solid media for 48 hours and harvested for RNA isolation

Project description:This study profiled the expression of miRNA during myogenesis of the C2C12 mouse myoblast cell line. 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.
