Myoblasts and Myotubes

ABSTRACT: Satellite cells play an important role in post-natal growth and regeneration of skeletal muscle. They can be defined as a population adult muscle stem cells based on their self renewal capability and ability to differentiate into skeletal muscle fibers. Functional Retinoblastoma protein (pRb) is essential for the process of skeletal muscle differentiation in satellite cell derived primary myoblasts. Furthermore, the biochemical function of pRb is largely associated with its ability to interact with chromatin modifying factors such as histone deacetylases (HDACs) and histone methyltransferases thus inhibiting transcription of target gene promoters. Hence, expression profiling of pRb null primary myoblasts and myotubes will provide a global picture of the downstream targets of pRb transcriptional regulation in relation to cell cycle control, apoptosis inhibition, and muscle differentiation.

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.

Transcription profiling of mouse muscle satellite cell-derived myoblasts (MyoD-/-, p53-/-)

Project description:Muscle satellite cells are a self-renewing pool of stem cells that give rise to daughter myogenic precursor cells in adult skeletal muscle. Published and preliminary data indicated that MyoD and p53 genes are involved in satellite cell differentiation. We would like to know what downstream genes of both transcription factors are affected in satellite cell-derived myoblasts (MyoD-/-, p53 -/-). Experiment Overall Design: this experiment include 3 samples and 25 replicates

Expression data from primary myoblasts with active Beta-catenin

Project description:Regeneration of the adult skeletal muscle tissue relies on a population of muscle stem cells called satellite cells. During tissue repair, satellite cells exhibit active canonical Wnt/beta-catenin signaling. To identify genes that become transcribed following activation of the Wnt/β-Catenin pathway in satellite cells, we performed microarray analysis of primary myoblasts expressing an active form of beta-catenin

Gene expression response to Pax7 in murine myoblasts

Project description:Pax7 is a paired box transcription factor that is central to skeletal muscle satellite cell function Microarrays were used to examine gene expression after primary murine satellite cell-derived myoblasts were retrovirally infected with constructs encoding Pax7, PAX7-FOXO1A, dominant negative Pax7-ERD and retroviral control.

Expression data from Rspo1-null differentiating primary myoblasts

Project description:Regeneration of the adult skeletal muscle tissue relies on a population of muscle stem cells called satellite cells. During tisse repair, satellite cells exhibit active canonical Wnt/beta-catenin signaling. Rspo1 is a modulator of Wnt signaling in many tissue, and is expressed by muscle progenitor cells. To identify genes that become transcribed following activation of the Wnt/β-Catenin pathway in satellite cells, we performed microarray analysis of primary myoblasts expressing an active form of beta-catenin

Chromatin accessibility landscape of freshly-isolated human and murine muscle satellite cells and myoblasts

Project description:Muscle stem cells, also known as satellite cells, represent the main myogenic population accounting for skeletal muscle homeostasis and regeneration. Here, using the Assay for Transposase Accessible Chromatin followed by sequencing (ATAC-seq), we investigated the epigenetic landscape of activated human and murine satellite cells. Our analysis identified a compendium of putative regulatory elements defining activated satellite cells and myoblasts, respectively.

Microarray analysis of gene expression regulation by Vgll3 in mouse satellite cell-derived myoblasts

Project description:Hippo effectors Yap and Taz, Vgll1-4 and Tead 1-4 transcription factors have been linked to satellite cell/ myoblast proliferation and differentiation, muscle function and disease. The molecular function of Vgll3 in skeletal muscle stem cells was investigated using analysis of gene expression by microarrays to determine Vgll3 mediated gene expression changes and compare those to previously determined Taz and Yap mediated changes. Satellite cell-derived myoblasts were transduced with Vgll3 retrovirus for 24h or 48h, with empty retrovirus vector as control. Triplicate microarray analysis of empty vector controls and Vgll3 transgenic primary myoblasts were conducted.

RNA-seq profiling of C/EBPβ-overexpressing myoblasts [proliferating myoblasts]

Project description:We previously identified C/EBPβ as an inhibitor of myogenic differentiation and a regulator of muscle satellite cell self-renewal. We found that C/EBPβ is regulated during the transition from proliferation to growth arrest in myoblasts and overexpression of C/EBPβ in myoblasts promotes cell growth arrest in vitro and improves engraftment of satellite cells into the stem cell niche in vivo. To identify the molecular mechanism by which C/EBPβ regulates myoblast proliferation and growth arrest, we performed RNA-seq on C/EBPβ-overexpressing myoblasts.

Transcriptomic analysis of day 1 (D1) differentiating WT and HDAC11-deficient mouse myoblasts

Project description:To get insight into the transcriptomic changes caused by HDAC11 loss at early myogenic differentiation, we performed RNA sequencing (RNA-Seq) in 24 h differentiated primary myoblasts from WT and HDAC11-deficient mice. Satellite cell-derived primary myoblasts were obtained after FACS isolation of skeletal muscle cells by growing them at low confluence in proliferation medium. To induce myoblast differentiation, cells were plated at high confluence and changed to differentiation media. Gene Ontology (GO) analysis of the genes upregulated in HDAC11 KO differentiating myoblasts revealed a statistically significant enrichment of cell cycle-related processes while the downregulated genes in HDAC11 KO differentiating myoblasts were enriched in “muscle system process” and “muscle contraction” GO categories.
