Project description:ChIP-seq data (H3K4Me3, H3K27Ac histone modifications) of Hodgkin lymphoma cell line L-428. Samples were processed as previously described (Sud et al., 2018). The files are in bam format, aligned to build 37 of the human genome.

Project description:The transcription factor network in Hodgkin lymphoma (HL) represents a unique composition of proteins found in no other hematopoietic cell. An aberrant downregulation of the B cell transcription factor EBF1 is observed in the B cell-derived Hodgkin and Reed/Sternberg (HRS) tumor cells. Herein, we elucidated the consequences of the down regulation of this factor in HL. To obtain a more comprehensive overview of EBF1 regulated genes in cHL cell lines, we performed a gene chip analysis comparing gene expression in tGFP-EBF1-transduced L-1236 and L-428 cells compared to samples transduced with vectors encoding only tGFP. 12 total samples were analyzed. Three independent samples were analyzed per condition and cell line.We generated the following pairwise comparisons using Bioconductor: tGFP-EBF1 L-428 < tGFP L-428; tGFP-EBF1 L-1236 < tGFP L-1236. Genes with an FDR≤ 5 % and a fold-change ≥ 2.0 and ≤ -2.0 were selected.

Project description:In situ promoter capture Hi-C on Hodgkin lymphoma cell line L-428 in experimental triplicates. Hi-C libraries were prepared as previously described (Orlando et al., 2018, https://currentprotocols.onlinelibrary.wiley.com/doi/pdf/10.1002/cphg.63). Promoter capture was based on 32,313 biotinylated 120-mer RNA baits (Agilent). Hi-C libraries were sequenced using Illumina HiSeq 2000 technology. The files are in FASTQ format.

Project description:Background Epigenetic changes are involved in the extinction of the B-cell gene expression program of classical Hodgkin lymphoma. However, little is known regarding epigenetic similarities between classical Hodgkin lymphoma and plasma cell myeloma cells, both of which share an extinction of the gene expression program of mature B-cells. Design and methods Global histone H3 acetylation patterns were determined in cell lines derived from classical Hodgkin lymphoma, plasma cell myeloma and B-cell lymphoma by chromatin immunoprecipitation and subsequent hybridization onto promoter tiling arrays. H3K27 trimethylation was analyzed by chromatin immunoprecipitation and real-time DNA-PCR for selected genes. Epigenetic modifications were compared to gene expression data. Results B-cell characteristic genes were hypoacetylated in classical Hodgkin lymphoma and plasma cell myeloma cell lines, as demonstrated by comparison of their histone H3 acetylation patterns to those of B-cell lines. However, the number of genes jointly hyperacetylated and expressed in classical Hodgkin lymphoma and plasma cell myeloma cell lines, such as IFR4/MUM1 and RYBP, is limited. Moreover, H3K27 trimethylation for selected B-cell characteristic genes revealed that this additional epigenetic silencing is much more prevalent in classical Hodgkin lymphoma as compared to plasma cell myeloma. Conclusion Our epigenetic data support the view that classical Hodgkin lymphoma is characterized by an abortive plasma cell differentiation with a down-regulation of B-cell characteristic genes but without activation of most plasma cell typical genes.

Gene expression analysis of Hodgkin lymphoma (cHL) and B-cell lines: Microarray data for three Hodgkin lymphoma cell lines (KM-H2, L1236, L428) and the B-cell line Namalwa that were published previously by our group (GEO accession GSE8388) were analyzed together with newly generated data for the B-cell lines SU-DHL4 and SU-DHL6. For all cell lines, RNA was isolated according to standard protocols (Qiagen, Hilden, Germany) and used for Affymetrix GeneChip hybridization (HG-U133A). Microarrays were normalized using RMA, and differential expression was calculated using moderated t-test. The gene expression profiles of the cell lines were generated in duplicates.
