Project description:Knockdown of MLL5 led to deregulation of S phase. To understand the molecular basis for this phenotype, we performed microarray analysis of S phase synchronized myoblasts. Genes differentially regulated by MLL5 knock down were revealed by microarray analysis using NIA15K mouse chips. Control and knock down cells were synchronized at G0 by suspension culture and reactivated to enter S phase by replating for 24hrs in growth medium.

Project description:Male mice but not female Mll5 -/- mice are infertile. This study showed that post-meiotic spermatogenic maturation is impaired in Mll5 -/- mice. In order to investigate the role of Mll5 in spermatogenesis, a transcriptome analysis of whole testes from Mll5 knock out and wildtype mice was performed. Affymetrix Mouse Exon chips were hybridized with testes material from three individual male mice from each wild-type or Mll5 -/- genotype, in order to identify gene regulation differences attributed to the loss of Mll5. One-way ANOVA: wildtype vs. Mll5-/-

Project description:Analysis of Early Myogenesis Reveals an Extensive Set of Transcriptional Regulators Whose Knock-down Can Inhibit Differentiation 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.
