Protein synthesis during myoblast differentiation

Project description:Mole (MSR) and fractional (FSR) synthesis rates of proteins during C2C12 myoblast differentiation were investigated. Myoblast cultures supplemented with D2O during 0-24 h or 72-96 h of differentiation were analysed by LC-MS/MS to calculate protein FSR and MSR after samples were spiked with yeast alcohol dehydrogenase (ADH1).

Effect of depletion of PRR33 on gene expression during myoblast differentiation

Project description:Coordinated cytoskeleton-mitochondria organization during myogenesis is very essential for muscle development and function. Currently, our understanding of the underlying regulatory mechanisms is still inadequate. Here, we identified a novel muscle specific protein PRR33, which is up-regulated during myogenesis and acts as a promyogenic factor. Depletion of PRR33 in C2C12 represses myoblast differentiation. Interactome and transcriptome analyze reveal that PRR33 regulates cytoskeleton and mitochondrial function. Remarkably, PRR33 interacts with DESMIN, a key regulator of cytoskeleton-mitochondria organization in muscle cells. Abrogation of PRR33 in myocytes substantially abolishes the interaction of DESMIN filaments with mitochondria and can result in abnormal intracellular accumulation of DESMIN and mitochondrial disorganization/dysfunction in myofibers. Together, our study shows that PRR33 and DESMIN constitute an important regulatory module coordinating mitochondrial organization with muscle differentiation.

Identification of proteolytic events during C2C12 myoblast differentiation

Project description:Identification of product of proteolysis during C2C12 myoblast differentiation using subtiligase N-terminomics. Different cell populations collected during a time-course of differentiation (4 days) were used for N-terminal labeling in a forward degradomics approach (n=2). Day0 population= Myoblasts, Day1 populations= live cells and dead cells, Day4 populations= Myotubes and Reserve cells. Additionally, cleavages events generated by mouse caspase-3 at early stages of differentiation (Day 0 and 1) was evaluated using a reverse degradomics approach on myoblasts and live cells (n=2).

Ethanol effect on myoblast differentiation

Project description:Expression profiling of C2C12 myoblast cells treated with ethanol during differentiation. Ethanol inhibits C2C12 differentiation. Results provide insight into signaling pathways altered by ethanol during differentiation. When C2C12 cells reached 70% confluence in growth medium containing 20% FBS, culture medium was changed to differentiation medium containing 2% horse serum with and without 100mM ethanol. Samples were harvested from day zero (just prior to differentiation) as well as days 1, 2 and 3 following onset of differentiation with and without alcohol treatment. RNA was isolated using the Qiagen RNA mini-kit.

Genomic mapping of Six1 binding sites during skeletal myoblast differentiation

Project description:In this study, the C2C12 cell line, a model used to study myogenesis and regeneration, was allowed to differentiate from myoblast precursor cells to myotubes. Cells were harvested at 3 different timepoints to perform ChIP-on-Chip of Six1, which is a key muscle regulator. We identified global loci bound by Six1 during skeletal myoblast differentiation. C2C12 Myoblasts were allowed to differentiate into myotubes. Cells at three timepoints were harvested for ChIP-on-Chip, including myoblasts stage, 24h after differentiation and myotubes (96h after differentiation). Myotubes were detached from the undifferentiated myoblast reserve cells using diluted trypsin. 3 independent biological replicates were used for each time point experiment. A microarray set counts 3 arrays (Custom Arrays A, B and C) for a total of approximately 2.9 million probes.
