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.

Project description:The objective of the study is to caracherize the genes that are regulated by Srf in myoblasts at day 0 (J0) and in differentiated cells at day 1 (J1) and day 3 (J3). We used microarrays to investigate gene expression in Srf KO and Srf WT muscle cells at day 0 (J0), day 1 (J1) and day 3 (J3) of differentiation
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.
Project description:Myoblasts harvested from a postnatal day 2 WT and Foxj3 KO litter. We used Affymetrix microarrays to identify dysregulated transcripts in Foxj3 mutant myoblasts. Keywords: mutant analysis, skeletal 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.
Project description:The purpose of this study was to determine the miRNA expression profile of in vitro differentiation of human skeletal muscle cells and to couple changes in individual miRNA expression to effects on target genes by transcriptome profiling of mRNA expression. mRNA expression profiling at three different time points during the in vitro differentiation process of human skeletal muscle cells from three subjects. RNA was harvested from myoblasts before and 4 and 10 days after induction of differentiation. Temporal, time-course design with paired analysis (3 subjects). Biological replicates: 3 at day 0, 3 at day 4, and 3 at day 10. One replicate per array.
Project description:The purpose of this study was to determine the miRNA expression profile of in vitro differentiation of human skeletal muscle cells and to couple changes in individual miRNA expression to transcriptional output of target genes. miRNA expression profiling at six different time points during the in vitro differentiation process of human skeletal muscle cells from six subjects. RNA was harvested from myoblasts before induction of differentiation and at every other day for 10 following days. Temporal, time-course design with paired analysis (6 subjects). Biological replicates: 6 at day 0, 6 at day 2, 6 at day 4, 6 at day 6, 6 at day 8, and 5 at day 10. One replicate vs common reference RNA pool per array.
Project description:The purpose of the study was to further understand the molecular mechanisms mediating the effect of Crhr2 signaling on insulin sensitivity in skeletal muscle. To that end we compared the gene expression profile of skeletal muscle obtain from both Crhr2 KO and WT littermates using gene expression microarray. RNA was extracted from skeletal muscle of 4 Crhr2 KO and 4 WT littermates. RNA from 2 KO or 2 WT mice was pooled and analyzed using Affymetrix U74Av2 GeneChips.
