TranscriptomicsGene Expression Profiles of cutaneous B-cell lymphoma
We studied gene expression profiles of 17 cutaneous B-cell lymphomas that were collected with 4-6 millimeter skin punch biopsies. We also included tissue from 2 cases of mycosis fungoides (MF), 3 normal skin biopsies and 3 tonsils to create a framework for further interpretation. A hierarchical clus...

GenomicsGenome-wide binding profiles of the B-Myb-MuvB complex in HeLa cells
To identify genomic regions bound by B-Myb and LIN9 (a subunit of the MuvB complex), we performed ChIP-Sequencing (ChIP-Seq) using chromatin from proliferating HeLa cells in which we can detect a robust association between B-Myb and subunits of the MuvB complex. This analysis allowed us identify lat...

GenomicsDNA Cytosine Hydroxymethylation Levels Are Distinct Among Peripheral Blood Leukocytes
Peripheral blood leukocytes are the most commonly used surrogates to study epigenome-induced risk and epigenomic response to disease related stress. We considered the hypothesis that the TET enzyme catalyzed hydroxymethylation of 5mC to 5hmC might vary among peripheral blood leukocytes and reflect t...

TranscriptomicsImpact of Hells loss-of-function on DNA methylation in B cells during humoral immune responses: kinetic comparison of Mb1-Hells knockout and control mice by single-cell RNA sequencing
We are interested in deciphering the mechanism by which DNA methylation in late B cell differentiation affects humoral immune response. We chose to study a very rare immunodeficiency called ICF type 4, where a point mutation in a gene encoding the protein HELLS causes a lack of both circulating anti...

TranscriptomicsScRNA-seq analysis of naive, germinal center and memory B cells of mice immunized with homologous and heterologous prime:boost combinations of whole-cell pertussis or acellular pertussis vaccines
Since the introduction of new generation pertussis vaccines, resurgence of pertussis is observed in many developed countries. Former whole-cell pertussis vaccines (wP) are able to protect against disease and transmission but have been replaced in several industrialized countries because of their rea...

GenomicsRegulation of Mammalian Cell Growth and Survival By an RNA Polymerase II-Pausing Factor (ChIP-seq)
Many mammalian genes are occupied by paused RNA polymerase II (pol II) at promoter-proximal regions on both sides of transcription start sites (TSSs). However, the consequences of pol II pausing on gene expression and cell biology are not fully understood. Here we report that genetic ablation of t...

GenomicsTriplication of a 21q22 region contributes to B cell transformation through HMGN1 overexpression and loss of histone H3 Lys27 trimethylation [ChIP-seq]
Children with Down syndrome (DS) have a 20-fold increased risk of developing B cell acute lymphoblastic leukemia (B-ALL). Polysomy 21 (i.e., extra copies of chr.21) is also the most frequent somatic aneuploidy among all B-ALLs. Additional B-ALLs harbor intrachromosomal amplifications of chr.21q22 (i...

TranscriptomicsTranscription profiling of chicken Bcl6 deficient DT40 B cell line to investigate the targets of Bcl6 which is required for germinal center formation
The transcription factor Bcl6 is required for germinal center formation and deregulated expression of Bcl6 has been observed in lymphomas. To gain insight to the function of Bcl6 in terminal differentiation of B cells to plasma cells and to investigate the targets of Bcl6, we established a Bcl6 defi...
