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 study the function of E3 ligase Huwe1 knockdown on C2C12 proliferation and differentiation, we use mRNA-seq to compare gene expression profiles between control wild-type C2C12 myoblasts and two Huwe1 knockdown C2C12 cell lines generated by different shRNAs on differentiation Day 0 (proliferation medium) and Day 6 (differentiation medium for 6 days). To study the potential roles of Huwe1 in maintainance of muscle morphology, we use mRNA-seq to compare gene expression profiles between control and Huwe1 knockdown myotubes. To study whether downregulation of USP10 deubiquitinase is of functional significance during muscle differentiation, we compare gene expression profiles between control wildtype and USP10 overexpressing C2C12 cells on differentiation Day 6.
Project description:We tested the hypothesis that ectopic expression of the MyoD-dependent gene program in differentiating myoblasts and myotubes compromises the integrity of the plasma membrane/sarcolemma by using a doxycycline-inducible system to overexpress MyoD in C2C12 myoblasts during differentiation. The overarching goals of this analysis pipeline were to (a) determine changes in transcriptional profiles upon sustained overexpression of MyoD during and upon differentiation; and, (b) utilize these profiles to identify potential drivers of sarcolemmal fragility that exacerbate myofiber damage and loss in dystrophic muscle. We used microarrays to generate information about transcriptional profiles in differentiating myoblasts and myotubes overexpressing the myogenic transcription factor myoblast determination protein 1 (MyoD1).
