Project description:We used the dTAG protein degradation system to rapidly deplete transcription factor EBF1 in the B cell culture. After treatment with dTAG-13 for 6 hours, we performed ChIP-seq, ATAC-seq, and RNA-seq. After the treatment, EBF1 is completely absent from the chromatin. This leads to the closure of EBF1 binding sites and changes in the target gene expression. This approach allowed us to identify direct targets of EBF1 and show the importance of EBF1 for open chromatin maintenance.

Project description:EBF1 is essential for B cell specification and commitment. To explore the dynamics of EBF1 initiated B cell programming, we performed EBF1 ChIP-seq, ATAC-seq, bisulfite-seq, RNA-seq and several histone ChIP-seq analyses at different stages of the transition from Ebf1-/- pre-pro-B to pro-B triggered by EBF1 restoration. We also performed Pax5 ChIP-seq in Ebf1-/- pre-pro-B cell and EBF1-restored pro-B cell to study the pioneering function of EBF1 that allows other transcription factors to access certain chromatin sites.

Project description:EBF1 is crucial transcription factor in B cell lineage and Ebf1 -/- hematopoietic stem cells are arrest in early B cell development and disable to express CD19. miR-195 transduction is able to overcome Ebf1 deficiency and cause CD19 positive cells. ATAC-seq data of these cells provided a new insight into relationship between early B cell differentiation and micro-RNA regulation.
