Description
Mutations in the RUNX1 gene (RUNX1mut) have been established in myelodysplasia (MDS), de novo and secondary acute myeloid leukaemia (AML), and are in general associated with an unfavourable clinical outcome. Familial RUNX1 mutations are associated with familial thrombocytopenia and these patients have a predisposition to AML development. However, a number of studies have been performed so far in mice which might be distinct from the human hematopoietic system. Therefore we studied the cellular phenotypes, the RUNX1 binding pattern and expression profile induced by RUNX1mut in cord blood (CB) CD34+ cells and induced pluripotent stem cell (iPSC) and compared these findings to primary RUNX1mut AML's. Overall design: A total of nine samples were subject to RNA-Seq including RUNX1mut-transduced cord blood CD34 cells and time-course iPSCs.
Publication Title
RUNX1 mutations enhance self-renewal and block granulocytic differentiation in human in vitro models and primary AMLs.

Description
We used an inducible shRNA system and RNA-Seq to examine gene expression changes in acute myeloid leukemia THP1 cells following silencing of RUVBL2. RUVBL2 is a AAA+ ATPase that functions in a number of cellular processes, including chromatin remodeling and transcriptional control, and is critical for survival of acute myeloid leukemia cells and in vivo disease progression. Overall design: Total cellular RNA was extracted using the RNeasy Plus Mini Kit from THP1 cells transduced with RUVBL2-specific inducible shRNA, following 2 and 4 days exposure to doxycycline or medium controls. In total, 6 pairs of control and doxycycline-treated samples were analysed (3 control and 3 doxycycline-treated for each time-point).
Publication Title
The AAA+ATPase RUVBL2 is essential for the oncogenic function of c-MYB in acute myeloid leukemia.

Description
In MLL-rearranged (MLLr) leukemias the N terminal part of the MLL gene can be fused to over 60 different partner genes. Here, we investigate the genome wide binding of the MLL-AF9 and MLL-AF4 fusion proteins and their epigenetic signatures in order to define a core set of MLLr targets. We uncover both common as well as specific MLL-AF9 and MLL-AF4 target genes, which are all marked by H3K79me2, H3K27ac, and H3K4me3. Apart from promoter binding, we also identify MLL-AF9 and MLL-AF4 binding at specific subsets of non overlapping active distal regulatory elements. Despite this differential enhancer binding MLL-AF9 and MLL-AF4 still share a common gene program, which represents part of the RUNX1 gene program and constitutes of CD34+ and monocyte specific genes. Comparing these datasets revealed several zinc finger transcription factors as potential MLL-AF9 co-regulators. Together these results suggest that MLL-fusions collaborate with specific subsets of TFs to aberrantly regulate the RUNX1 gene program in 11q23 AMLs. Overall design: Genome-wide (ChIP-seq) binding of MLL, AF9, AF4, H3K4me3, H3K27ac, H3K79me2 and RUNX1 in THP-1 and MV4-11 AML cell lines. Expression Profiling (RNA-seq) of THP-1 and MV4-11 cell lines, as well as 5 MLL-AF9 positive patient blasts.
Publication Title
MLL-AF9 and MLL-AF4 oncofusion proteins bind a distinct enhancer repertoire and target the RUNX1 program in 11q23 acute myeloid leukemia.

Description
We sequenced mRNA from triplicate log-phase cultures of BY4741 (WT) transformed with pRS313-HA3-SSN6 and taf14D transformed with pRS313-HA3-SSN6 (empty vector), full-length pRS313-TAF14-HA3-SSN6, or pRS313-taf14W81A-HA3-SSN6 cultured in synthetic complete media lacking histidine. Overall design: Examination of changes in gene expression when the YEATS domain of Taf14 is mutated so it cannot bind acetyl-H3.

Description
Innate immune memory is the phenomenon whereby innate immune cells such as monocytes or macrophages undergo functional reprogramming after exposure to microbial components such as LPS. We apply an integrated epigenomic approach to characterize the molecular events involved in LPS-induced tolerance in a time dependent manner. ChIP-seq, RNA-seq, WGBS and ATAC-seq data were generated. This analysis identified epigenetic programs in tolerance and trained macrophages, and the potential transcription factors involved. Overall design: Time-course in vitro culture of human monocytes. Two innate immune memory states can be induced in culture through an initial exposure of primary human monocytes to either LPS or BG for 24 hours, followed by removal of stimulus and differentiation to macrophages for an additional 5 days. Cells were collected at baseline (day 0), 1 hour, 4 hour, 24 hour and 6 days.

The heat-shock stress response was studied at the level of exons using Affymetrix Exon-array profiling for both sense and anti-sense transcripts. Sense transcript profiling was done as per the protocol of Affymetrix Exon 1.0 ST array and anti-sense transcript array profiling was done using a modified protocol (Xijin Ge et al., BMC Genomics. 2008 Jan 22;9:27).
