Project description:To study the function of EBF1-H240 residue, genome-wide EBF1 ChIP was performed in A-MuLV transformed pro-B (Ebf1fl/fl;RERTCre) cells transduced with Ebf1wt and Ebf1H240A expressing vectors.
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 deficient pre-pro B-cells (Fraction A) can be cultured in the presence of stromal feeders and cytokines. The retroviral transduction of these cells with Ebf1 was used as gain-of-function experiment for the analysis of direct and functional target genes of Ebf1. Ebf1 deficient pre-pro B-cells were retrovirally transduced with an Ebf1-expressing or control retrovirus. 24h after transduction the infected cells were isolated and their gene expression profile was compared.
Project description:Early B cell factor 1 (EBF1) is one of the key transcription factors required for orchestrating B-cell lineage development. Although studies have shown that Ebf1 haploinsufficiency is involved in the development of leukemia, no study has been conducted that characterizes the global effect of Ebf1 heterozygosity on the proteome of pro-B lymphocytes. Here, we employ both DIA (Data Independent Acquisition) and shotgun DDA (Data Dependent Acquisition) workflows for profiling proteins that are differently expressed between Ebf1+/+ and Ebf1+/- cells. Both DDA and DIA were able to reveal the downregulation of the EBF1 transcription factor in Ebf1+/- pro-B lymphocytes. Further examination of differentially expressed proteins by DIA revealed that, similar to EBF1, the expression of other B-cell lineage regulators, such as TCF3 and Pax5, is also down-regulated in Ebf1 heterozygous cells. Functional DIA analysis of differentially expressed proteins showed that EBF1 heterozygosity resulted in the deregulation of at least 8 transcription factors involved in lymphopoiesis, and to the deregulation of key proteins playing crucial roles in survival, development and differentiation of pro-B lymphocytes.
