Dynamic analysis of gene expression and genome wide transcription factor binding during lineage-specification of multipotent progenitors [ER]

ABSTRACT: FDCPmix cells were infected with Gata1 and Pu1 ER fusion proteins and microarrayed after induction to reveal genes regulated by each factor as part of a study investigating the differentiation of a multipotential cell-line to erthroid and myeloid fates. We used the paradigmatic 'GATA-PU.1 axis’ to explore, at systems-level, dynamic relationships between transcription factor (TF) binding and global gene expression programs as multipotent cells differentiate. We combined global ChIPSeq of GATA1, GATA2 and PU.1 with expression profiling during differentiation to erythroid and neutrophil lineages. Our analysis reveals (i) differential complexity of sequence motifs bound by GATA1, GATA2 and PU.1; (ii) the scope and interplay of the GATA1 and GATA2 programs within, and during transitions betwee
