BRD4 localization to lineage-specific enhancers is associated with a distinct transcription factor repertoire [mRNA-Seq]

We examined context specific function of BRD4 in promoting lineage specific gene expression and show that BRD4 is essential for osteoblast differentiation. Overall design: We performed mRNA sequencing from hFOB cells (undifferentiated and differentiated for 5 days into osteoblastic lineage) following BRD4 inhibition by JQ1 or siRNA mediated depletion. The mRNA-Seq includes namely 7 conditions: undifferentiated hFOBs treated with DMSO or non-targeting control siRNA (siCNTR), differentiated hFOBs with DMSO or siCNTR treatments; differentiated hFOBs treated with JQ1 or two siRNAs against BRD4 (#3 & #4). The libraries were performed in triplicates.
