Transcription profiling of mouse embryonic fibroblasts isolated from Myod-/-Myf-/- mice were tranduced with either MDER or MDER+Myog, MDER was activated by the addition of beta-estradiol and samples collected at multiple time points

Project description:We used a combination of genome-wide and promoter-specific DNA binding and expression analyses to assess the functional roles of Myod and Myog in regulating the program of skeletal muscle gene expression. Our findings indicate that Myod and Myog have distinct regulatory roles at a similar set of target genes. At genes expressed throughout the program of myogenic differentiation, Myod can bind and recruit histone acetyltransferases. At early targets, Myod is sufficient for near full expression; whereas, at late expressed genes Myod initiates regional histone modification but is not sufficient for gene expression. At these late genes, Myog does not bind efficiently without Myod, however, transcriptional activation requires the combined activity of Myod and Myog. Therefore, the role of Myog in mediating terminal differentiation is, in part, to enhance expression of a subset of genes previously initiated by Myod. Mouse embryonic fibroblasts isolated from Myod-/-Myf-/- mice were tranduced with either MDER or MDER+Myog. MDER was activated by the addition of beta-estradiol. Cells were induced to differentiate for various times, and triplate samples were collected from the indicated time points.

Staufen1 inhibits MyoD translation to actively maintain muscle stem cell quiescence

Project description:Tissue regeneration depends on the timely activation of adult stem cells. In skeletal muscle, the adult stem cells maintain a quiescent state and proliferate upon injury. We show that muscle stem cells (MuSCs) use direct translational repression to maintain the quiescent state. High resolution single molecule and single cell analyses demonstrate that quiescent MuSCs express high levels of Myogenic Differentiation1 (MyoD) transcript in vivo, whereas MyoD protein is absent. RNA pulldowns and co-stainings show that MyoD mRNA interacts with Staufen1, a potent regulator of mRNA localization, translation, and stability. Staufen1 prevents MyoD translation through its interaction with the MyoD 3’UTR. MuSCs from Staufen1 heterozygous (Staufen1+/-) mice have increased MyoD protein expression, exit quiescence, and begin proliferating. Conversely, blocking MyoD translation maintains the quiescent phenotype. Collectively, our data show that MuSCs express MyoD mRNA and actively repress its translation to remain quiescent yet primed for activation.

MicroRNA expression profiling of quiescent and activated muscle stem cells

Project description:MicroRNA expression profiling during muscle stem cell activation. Quiescent muscle stem cells from uninjured muscles and activated muscle stem cells from injured muscles at indicated time points were isolated by FACS. MicroRNA expression profiling during muscle stem cell activation using real-time PCR based miRNA arrays. Muscle stem cells were harvested at indicated time points (0hr, 36hr, 60hr and 72hr) after injury. 3 technical replicates were performed. Supplementary files: Raw data (Ct) and complete processed data (dCt, ddCt, fold-change) by platform.

Gene profiling of quiescent and activated skeletal muscle satellite cells by an in vivo approach

Project description:The satellite cell of skeletal muscle provides a paradigm for quiescent and activated tissue stem cell states. We have carried out transcriptome analyses by comparing satellite cells from adult skeletal muscles, where they are mainly quiescent, with cells from growing muscles, regenerating (mdx) muscles, or with cells in culture, where they are activated. Our study gives new insights into the satellite cell biology during activation and in respect with its niche. We used microarrays to study the global programme of gene expression underlying adult satellite cell quiescence compared to activation states and to identify distinct classes of up-regulated genes in these two different states Skeletal muscle satellite cells were isolated by flow cytrometry using the GFP fluorescence marker from Pax3GFP/+ mice skeletal muscle. The transcriptome of quiescent satellite cells from adult Pax3GFP/+ muscle was compared to the transcriptome of activated satellite cells obtained from three different samples: 1) regenerating Pax3GFP/+:mdx/mdx muscle (Ad.mdx) , 2) growing 1 week old Pax3GFP/+ muscle (1wk), and 3) adult Pax3GFP/+ cells after 3 days in culture (Ad.cult).

Genome-wide expression analysis of quiescent versus activated muscle stem cells (satellite cells)

Project description:We performed genome-wide gene expression analysis of quiescent/activated muscle stem cells isolated from mouse skeletal muscle by flow cytometry. We analyzed the global changes in gene expression occurring within muscle stem cells (satellite cells) in homeostatic conditions or after cardiotoxin (CTX) injury (3 days). Pure satellite cell populations from dissociated skeletal muscle from mice were isolated using a well-established flow cytometry protocol gating on integrin a7(+) (positive selection) and Lin- (CD31, CD45, CD11b, Sca1) (negative selection).

Myogenesis MyoD

Project description:The transcription factor MyoD can coax na?e fibroblasts or otherwise committed cells to adopt the skeletal muscle phenotype by activating the muscle gene expression program. Activation of muscle gene expression occurs in quantal steps with not all the target genes of MyoD being activated at the same time. Some genes are induced in the initial phases, others at later stages despite the fact that MyoD is present throughout the differentiation process. MyoD is post-translationally modified by phosphorylation, ubiquitination, and acetylation. Here, we have employed a model system in which MyoD and its non-acetylatable version were inducibly expressed in mouse embryonic fibroblasts derived from mice to investigate how MyoD acetylation may contribute to differential gene activation. Keywords: Time-Series
