GenomicsA biochemical basis for toggling enhancers from the active to poised state in B cells
BCL6 is crucial for B-cell activation and lymphomagenesis. We used integrative genomics to explore BCL6 mechanism in normal and malignant B-cells. Surprisingly, BCL6 assembled distinct complexes at enhancers vs. promoters. At enhancers BCL6 preferentially recruited SMRT, which mediated H3K27 deacety...

TranscriptomicsGene expression data of BCR-ABL1 transformed B cell precursors from BCL6 wild-type and BCL6 knockout mice
To elucidate the mechanism of BCL6-mediated pre-B cell survival signaling, we investigated the gene expression pattern in BCR-ABL1-transformed BCL6+/+ and BCL6-/- B cell precursors. Pharmacological inhibition of BCR-ABL1 was performed with the BCR-ABL1 kinase inhibitor STI571 (Imatinib). BCR-ABL1 t...

TranscriptomicsRNA-seq transcriptome profiling of motor neurons (MNs) and surrounding white matter glia (WM) microdissected from pre-symptomatic mouse model of spinal muscular atrophy (SMA)
We report tramscriptome perturbations in MNs and WM of SMA mouse, prior to first morphological and biochemical synaptic defects Examination of ventral horn MNs and WM isolated from lumbar segment spinal cords from wild type (WT) and SMA mice

GenomicsInduction of sarcomas by mutant IDH2
More than 50% of patients with chondrosarcomas exhibit gain-of-function mutations in either isocitrate dehydrogenase 1 (IDH1) or IDH2. In this study, we performed genome-wide CpG methylation sequencing of chondrosarcoma biopsies and found that IDH mutations were associated with DNA hypermethylation ...

TranscriptomicsHigh resolution ChIP sequencing reveals novel bindings targets and prognostic role for SOX11 in Mantle cell lymphoma (RNA-Seq)
SOX11 (Sex determining region Y-box 11) expression is specific for MCL as compared to other Non-HodgkinM-bM-^@M-^Ys lymphomas. However, the function and direct binding targets of SOX11 in MCL are largely unknown. We used high-resolution ChIP-Seq to identify the direct target genes of SOX11 in a geno...

GenomicsA Stable Transcription Factor Complex Nucleated by Dimeric AML1-ETO Controls Leukaemogenesis
AML1-ETO, a fusion protein generated by the t(8;21) translocation in acute myeloid leukemia, is a transcription factor implicated in both gene repression and activation. We now show that, in leukemic cells, AML1-ETO resides in and functions through a stable protein complex (AETFC) that contains seve...

GenomicsA highly sensitive and robust method for genome-wide 5hmC profiling of rare cell populations
Investigations of 5-hydroxymethylcytosine (5hmC) in biologically and clinically samples and models with low cell numbers have been hampered by the low sensitivity and reproducibility using current 5hmC mapping approaches. Here, we develop a selective 5hmC chemical labeling approach using tagmentatio...

TranscriptomicsGene expression data of interleukin-7-dependent and BCR-ABL1-transformed pre-B cells
This analysis focused on identifying factors that protect pre-B cells against DNA double strand break (DSB)-mediated DNA damage stress during pre-B cell differentiation. Differentiation of pre-B cells including immunoglobulin light chain gene recombination were performed by withdrawal of interleuki...

TranscriptomicsEZH2 is required for germinal center formation and somatic EZH2 mutations promote lymphoid transformation
The EZH2 histone methyltransferase is highly expressed in germinal center (GC) B-cells and targeted by somatic mutations in B-cell lymphomas. Here we find that EZH2 deletion or pharmacologic inhibition suppresses GC formation and functions in mice. EZH2 represses proliferation checkpoint genes and h...

TranscriptomicsThe BCL6 RD2 domain governs commitment of activated B-cells to form germinal centers
Our data demonstrated that Bcl6 directly binds and represses trafficking receptors S1pr1 and Grp183 by recruiting Hdac2 through the RD2 domain. Deregulation of these genes impairs B-cell migration and may contribute to the Germinal Center failure in Bcl6RD2MUT mice. RNAseq was performed in endogeno...
