Project description:Overexpression of the transcription factor RUNX1 was studied in Nalm-6 precursor B acute lymphoblastic leukemia cells. The active enhancer histone marker H3K27ac and RUNX1 were measured using ChIP-seq. The effect on gene expression was analyzed using single cell RNA-sequencing.

Project description:Overwhelming evidence indicates that long non-coding RNAs have essential roles in tumorigenesis. Nevertheless, their expression and role in pediatric B-cell precursor acute lymphoblastic leukemia has not been extensively explored. Here, we conducted a comprehensive analysis of the long non-coding RNA transcriptome in ETV6/RUNX1 positive BCP-ALL, one of the most frequent subtypes of pediatric leukemia. An ETV6/RUNX1 expression signature was established, consisting of 596 lncRNAs (434 up and 162 down) using expression analysis of a series of primary patient samples. Subsequently, RNA sequencing from BCP-ALL cell lines and shRNA-mediated silencing of ETV6/RUNX1, illustrated that lnc-NKX2-3-1, lnc-TIMM21-5, lnc-ASTN1-1 and lnc-RTN4R-1 are bona fide ETV6/RUNX1 targets and could serve as novel biomarkers of this prevalent subtype of human leukemia.

Project description:Runt-related transcription factor 1 (RUNX1) is oncogenic in diverse types of leukemia and epithelial cancers where its expression is associated with poor prognosis. Current models suggest that RUNX1 cooperates with other oncogenic factors (e.g., NOTCH1, TAL1) to drive the expression of proto-oncogenes in T cell acute lymphoblastic leukemia (T-ALL) but the molecular mechanisms controlled by RUNX1 and its cooperation with other factors remain unclear. Integrative chromatin and transcriptional analysis following inhibition of RUNX1 and NOTCH1 revealed a surprisingly widespread role of RUNX1 in the establishment of global H3K27ac levels and that RUNX1 is required by NOTCH1 for cooperative transcription activation of key NOTCH1 target genes including MYC, DTX1, HES4, IL7R, and NOTCH3. Super-enhancers were preferentially sensitive to RUNX1 knockdown and RUNX1-dependent super-enhancers were disrupted following the treatment of a pan-BET inhibitor, I-BET151.

Project description:Despite absent expression in normal hematopoiesis, the Forkhead factor FOXC1, a critical mesenchymal differentiation regulator, is highly expressed in ~30% of HOXAhigh AML to confer blocked monocyte/macrophage differentiation. Through integrated proteomics and bioinformatics, we discovered that FOXC1 and RUNX1 interact through Forkhead and Runt domains respectively and cooccupy primed and active enhancers distributed close to differentiation genes. FOXC1 stabilises association of RUNX1, HDAC1 and Groucho repressor TLE3 to limit enhancer activity: FOXC1 knockdown induced loss of repressor proteins, gain of CEBPA binding, enhancer acetylation and upregulation of nearby genes, including KLF2. Furthermore, it triggered genome-wide redistribution of RUNX1, TLE3 and HDAC1 from enhancers to promoters leading to repression of self-renewal genes including MYC and MYB. Our studies highlight RUNX1 and CEBPA transcription factor swapping as a feature of leukemia cell differentiation, and reveal that FOXC1 prevents this by stabilising enhancer binding of a RUNX1/HDAC1/TLE3 transcription repressor complex, to oncogenic effect.

Project description:Around 20-25% of childhood acute lymphoblastic leukemias carry the TEL-AML1 (TA) fusion gene. It is a fusion of two central hematopoietic transcription factors, TEL (ETV6) and AML1 (RUNX1). Despite its prevalence, the exact genomic targets of TA have remained elusive. We evaluated gene loci and enhancers targeted by TA genome-wide in precursor B acute leukemia cells using global nuclear run-on sequencing (GRO-seq).
