Project description:Gene expression profiling was performed to identify Sfmbt1-dependent regulation in myogenic programs. To establish the magnitude of the Sfmbt1 effect on muscle cells, we have compared gene expression profiles of C2C12 cells transduced with lentiviruses expressing scramble shRNA control or shSfmbt1. Our analysis suggested that Sfmbt1 critically confers transcriptional silencing of muscle genes in myogenic progenitor cells.

Our analysis suggested that Sfmbt1 critically confers transcriptional silencing of muscle genes in myogenic progenitor cells. Two biological replicates for each sample group: C2C12 cells stably transduced with pLKO.1 expressing scramble shRNA control and C2C12 cells transduced with pLKO.1 shSFMBT1. Samples were independently cultured and RNAs were then harvested for microarray analysis.

Project description:Myogenesis is a tightly controlled process involving the transcriptional activation and repression of thousands of genes. Although many components of the transcriptional network are known for the later phases of myogenesis, relatively little work has described the transcriptional landscape within the first 24 hours, when myoblasts commit to differentiate. Through dense temporal sampling of differentiating C2C12 myoblasts, we identify 266 transcriptional regulators (TRs) whose expression is altered within the first 12 hours of myogenesis. A high-content shRNA screen of 76 TRs involving 427 stable lines identified 48 genes whose knockdown significantly inhibits differentiation of C2C12 myoblasts. These include known regulators of myogenesis (Myod1, Myog and Myf5), as well as 26 regulators not previously associated with the process. Of the TRs differentially expressed within the first 24 hours, two-thirds inhibited differentiation when knocked down. Surprisingly, a similar proportion (67%) of shRNAs targeting TRs whose expression did not change during differentiation also inhibited myogenesis, suggesting that both stably and differentially expressed TRs are essential for this complex differentiation program. This implies that microarray-based approaches that concentrate functional validation studies on differentially-expressed genes will fail to identify many genes that are critically implicated in complex biological processes. C2C12 myoblasts were differentiated into myotubes and sampled at various timepoints for gene expression measurement on Illumina Mouse WG-6v1.1 arrays. Cells grown in separate plates were harvested at 12 different timepoints: t_0h, t_1h, t_1.5h, t_2h, t_3h, t_6h, t_9h, t_12h, t_24h, t_48h, t_96h, t_144h. All harvests were performed in triplicate using growths from successive passages.

Project description:The goal of this study was to identify potentially novel mechanisms that mediate myoblast differentiation using the C2C12 cell as a myoblast model. The study started with an RNA-seq analysis to identify genes differentially expressed during myoblast differentiation. This analysis and subsequent functional analysis resulted in the identification of autophagy as one of the upregulated biological processes in differentiating myoblasts.

C2C12 myoblasts were differentiated into myotubes and sampled at various time points for gene expression measurement on MOE-430v2 chips. Cells grown in separate plates were harvested at 14 different time points: t_-24h, t_0h, t_0.5h, t_1h, t_1.5h, t_2h, t_3h, t_6h, t_9h, t_12h, t_24h, t_48h, t_96h, t_144h. Cells were also pre-treated with 50uM cycloheximide 1 hour prior to inducing differentiation and harvested at two time points: t_chx_1h, t_chx_3h. All harvests were performed in triplicate using growths from successive passages.
