Genome-wide maps of chromatin state and gene expression in control and TPA-stimulated pre-B leukemic 697 line

Project description:Linker histone H1 has been correlated with transcriptional inhibition, but the mechanistic basis of the inhibition and its reversal during gene activation has remained enigmatic. We report that H1-compacted chromatin, reconstituted in vitro, blocks transcription by abrogating core histone modifications by p300 but not activator and p300 binding. Transcription from H1-bound chromatin is elicited by H1 chaperone NAP1, which is recruited in a gene-specific manner through direct interactions with activator-bound p300 that facilitate core histone acetylation (by p300) and concomitant eviction of H1 and H2A/H2B. An analysis in B cells confirms the strong dependency on NAP1-mediated H1 eviction for induction of the silent CD40 gene and further demonstrates that H1 eviction, seeded by activator-p300-NAP1 interactions, is propagated over a CTCF-demarcated region through a distinct mechanism that also involves NAP1. Our results confirm direct transcriptional inhibition by H1 and establish a gene-specific H1 eviction mechanism through an activator-p300-NAP1-H1 pathway.

Transcriptomic effects of forced expression of FOXO3, PRDM1⍺ and PRDM1β in pre-B ALL cell line 697 [exp1]

Project description:Lentiviral constructs expressing candidate tumoure suppressor genes were transduced into 697 cells. Of the candidates FOXO3, two isoforms of PRDM1 (⍺ and β) suppressed growth in-vitro and in-vivo. To indentify tumour suppressor mechanisms we extracted RNA from triplicate 697 cultures four days after transduced with empty vector (SIN-SIEW) or constructs expressing FOXO3, PRDM1⍺ or PRDM1β. Approximately 90 million 100bp paired-end reads were generated per sample by illumina sequencing.

Genome-wide maps of factors and gene expression in pre-B leukemic 697 line

Project description:E2A, a basic helix-loop-helix (bHLH) transcription factor, plays a crucial role in determining tissue-specific cell fate, including differentiation of B cell lineages. In 5% of childhood acute lymphoblastic leukemia (ALL), the t(1,19) chromosomal translocation specifically targets the E2A gene and produces an oncogenic E2A-PBX1 fusion protein. While previous studies have demonstrated oncogenic functions of E2A-PBX1 in cell and animal models, the E2A-PBX1-enforced cistrome, the E2A-PBX1 interactome, and related mechanisms underlying leukemogenesis remain unclear. Here, by unbiased genomic profiling approaches, we identify the direct target sites of E2A-PBX1 in t(1,19)-positive pre-B ALL cells and show that, compared to normal E2A, E2A-PBX1 preferentially binds to a subset of gene loci co-bound by RUNX1 and gene-activating machineries (p300, MED1, and H3K27 acetylation). Using biochemical analyses, we further document a direct interaction between E2A-PBX1 and RUNX1 and show that E2A-PBX1 binding to gene enhancers is dependent on RUNX1, but not the DNA-binding activity harbored within the PBX1 homeodomain of E2A-PBX1. Transcriptome analyses and cell transformation assays further establish a significant RUNX1 requirement for E2A-PBX1-mediated target gene activation and leukemogenesis. Notably, the RUNX1 locus itself is also directly activated by E2A-PBX1, indicating a multilayered interplay between E2A-PBX1 and RUNX1. Collectively, our study provides the first unbiased profiling of the E2A-PBX1 cistrome in pre-B ALL cells and reveals a previously unappreciated pathway in which E2A-PBX1 acts in concert with RUNX1 to enforce transcriptome alterations for the development of pre-B ALL.
