Project description:Maps of genomic regions in proximity to the nuclear lamina were determined in undifferentiated C2C12 myoblasts (MBs) and 6 day differentiated C2C12 myotubes (MTs) using DamID with a Dam-Lamin B1-encoding lentivirus.
Project description:Muscle larva of a parasitic nematode Trichinella spp. lives a portion of muscle fiber transformed to a nurse cell (NC). The NC is formed from miss-differentiated muscle satellite cells which have fused with a parasite-invaded degenerating myofiber. Though originating from muscle cells, the NC is of non-muscular type.The NC is multinuclear and hypertrophic. Molecular mechanism of the NC development remains largely unknown. The microarray project was aimed at characterization of the NC transcriptome. The NCs were isolated by enzymatic digestion from infected mouse striated muscles. Murine C2C12 myogenic cell line (ATCC) was cultured in vitro. Differentiation of myoblasts into myotubes was carried out for 6 days in a high-glucose DMEM supplemented with 2% heat-inactivated horse serum, on the plates covered with laminin and collagen IV.The NC transcriptome was referred to the transcriptomes of C2C12 myoblasts and C2C12 myotubes in two sets of camparative expression microarray hybridization experiments, NC vs myoblasts and NC vs myotubes, respectively.
Project description:Mouse C2C12 myoblasts were used to mimic skeletal muscle differentiation in vitro.Using RNA-seq and MeRIP-seq, we generated the tascriptome and epitranscriptome data of undifferentited C2C12 myoblasts in growth medium (GM) and differentiated myotubes in differentitation medium for 4 days (D4).
Project description:To determine the lncRNA expression profile in C2C12 myoblasts and myotubes, we used mouse lncRNA microarray from Arraystar to examine the expression of lncRNAs in C2C12 myoblasts and myotubes.
Project description:To determine the circRNA expression profile in C2C12 myoblasts and myotubes, we used mouse circRNA microarray from Arraystar to examine the expression of circRNAs in C2C12 myoblasts and myotubes.
Project description:Investigate the genome-wide gene expression profiles of 50% and 95% confluent C2C12 myoblasts and C2C12 myotubes differentiated for 24 and 48 hours.
Project description:This study aimed to interrogate the interrelationship between 3D genome organization and global gene expression during muscle development using a mouse C2C12 cell line as an in vitro model. The C2C12 cell line is a well-established and extensively studied in vitro model derived from serial passage of myoblasts cultured from the thigh muscle of C3H mice after a crush injury. C2C12 cells divide when mitogens are present in the culture medium and spontaneously differentiate into muscle-like multinucleated (myotubes) cells if the medium is depleted of mitogens (i.e. serum; (Bischoff 1986)). C2C12 cells were either harvested as: 1) proliferating myoblasts (Myoblasts); 2) myotubes that were not treated with AraC (as such these myotubes contained myoblasts) - Myotubes(Day3); or 3) myotubes which were treated with AraC (myoblasts were largely depleted from these myotube cultures; Myotubes(Day7+AraC).
Project description:We show the application of 5mC antibody-based methylated DNA immunoprecipitation followed sequencing technology for high-through profiling of DNA methylation in mouse C2C12 myoblasts and myotubes. By analyzing the methylation status of immunoprecipitated DNA fragments, we generated genome-wide DNA methyaltion maps in mouse C2C12 myoblasts and myotubes. We find that DNA methylation levels in myoblasts at rDNA promter and coding regions are higher than that in myotubes but not changed in intergenic regions.
Project description:Gene expression analysis in human skeletal myoblasts (undifferentiated mononucleated cells, cultured in growth medium - 15% FBS) and human skeletal myotubes (pre-formed myotubes, cultured in differentiation medium – 2% horse serum) exposed to the HDACi TSA (50nM) for 24 hours TSA treated undifferentiated human primary myoblasts and terminally differentiated human myotubes
