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.

Total RNA samples were collected in triplicate from undifferentiated and differentiated P19 cells and MEFs, and labeled cDNA was made per Affymetrix protocol
