Project description:The regulatory networks of differentiation programs have been partly characterized; however, the molecular mechanisms of lineage-specific gene regulation by highly similar transcription factors remain largely unknown. Here we compare the genome-wide binding and transcription profiles of NEUROD2-mediated neurogenesis with MYOD-mediated myogenesis. We demonstrate that NEUROD2 and MYOD bind a shared CAGCTG E-box motif and E-box motifs specific for each factor: CAGGTG for MYOD and CAGATG for NEUROD2. Binding at factor-specific motifs is associated with gene transcription, whereas binding at shared sites is associated with regional epigenetic modifications but not as strongly associated with gene transcription. Binding is largely constrained to E-boxes pre-set in an accessible chromatin context that determines the set of target genes activated in each cell type. These findings demonstrate that the differentiation program is genetically determined by E-box sequence whereas cell lineage epigenetically determines the availability of E-boxes for each differentiation program. Comparing NeuroD2 induced neurogenesis and MyoD induced myogenesis by examining NeuroD2/MyoD binding sites in fibroblasts and P19 cells and corresponding changes in AcH4 using Chip-Seq. Assess chromatin accessibility using PvuII assay followed by high throughput sequencing.

Project description:MyoD and NeuroD2 are master regulators of myogenesis and neurogenesis and bind to a "shared" E-box sequence (CAGCTG) and a "private" sequence (CAGGTG or CAGATG, respectively). To determine whether private-site recognition is sufficient to confer lineage-specification, we generated a MyoD-mutant with the DNA binding specificity of NeuroD2. Our results demonstrate that redirecting MyoD binding from MyoD-private sites to NeuroD2-private sites, despite preserved binding to the MyoD/NeuroD2-shared sites, is sufficient to change MyoD from a master regulator of myogenesis to a master regulator of neurogenesis. RNA-seq profiling of mouse P19 cells transfected with MyoD, NeuroD2 and chimera mutants. The chimeric mutants are MyoD with the bHLH domain replaced with the NeuroD2 bHLH domain.
