Expression data from Hodgkin lymphoma cell lines UHO-1 and L-1236 transduced with shRNAs against GATA-3 or non-functional control shRNAs

ABSTRACT: The transcription factor network in Hodgkin lymphoma (HL) represents a unique composition of proteins found in no other hematopoietic cell. Among these factors, an aberrant expression of the T cell transcription factor GATA-3 is observed in the B cell-derived Hodgkin and Reed/Sternberg (HRS) tumor cells. Herein, we elucidated the regulation and function of this factor in HL To obtain a more comprehensive overview of GATA-3 regulated genes in cHL cell lines, we performed a gene chip analysis comparing gene expression in GATA-3-specific shRNA-transduced L-1236 and U-HO1 cells compared to samples transduced with vectors encoding scrambled shRNAs.

Three independent samples were analyzed per condition and cell line.We generated the following pairwise comparisons using Bioconductor: shRNA Gata-3 UHO-1 < control shRNA UHO-1; shRNA Gata-3 L1236 < control shRNA L-1236. Genes with an FDR≤ 25% and a fold-change ≥ 1.5 and ≤ -1.5 were selected.

Expression data from Hodgkin lymphoma cell lines L-428 and L-1236: L-428 and L-1236 cells were transduced with tGFP-EBF1 or as control tGFP-only.

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.

Expression study of the Hodgkin’s lymphoma cell line L-1236 upon CRISPR Cas9-mediated knockout of lymphotoxin alpha (LTA) compared to control

Project description:Persistent NF-κB activation is a hallmark of the malignant Hodgkin/Reed-Sternberg (HRS) cells in classical Hodgkin lymphoma (cHL). Analysis of the cHL cell-secreted key factors for NF-κB activation by chromatography and subsequent mass spectrometry revealed lymphotoxin-α (LTA) as the causative factor for autocrine and paracrine activation of canonical and noncanonical NF-κB in cHL cell lines. Upon CRISPR/Cas9-mediated gene knockout of LTA in the cell line L-1236, we performed expression analysis of LTA knockout versus control cells by using the Affymetrix array, Clariom S human, profiling tool.

Expression study of the Hodgkin’s lymphoma cell line L-1236 upon CRISPR Cas9-mediated knockout of lymphotoxin alpha (LTA) compared to control

Project description:Persistent activation of canonical and non-canonical NF-κB pathways is a hallmark of the malignant Hodgkin and Reed-Sternberg cells in classical Hodgkin lymphoma (cHL). We identified lymphotoxin alpha (LTA), which is secreted by the cHL cell line L-1236 in high concentrations. This cytokine contributes to the constitutive activation of the canonical and non-canonical NF-κB pathways. L-1236 cells were purchased from the DSMZ (Braunschweig, Germany) and cultured in RPMI (Gibco) with 10% heat-inactivated fetal calf serum (FCS; Gibco). Cells were transducted with the lentiCRIPSPR v2 vector containing gRNAs which target the second (g2) and the fourth exon (g3) of LTA. Following single cell clonal selection, L-1236 control cells (v2) and two LTA knockout (KO) clones g2_1 and g3_4 were cultured in normal culture medium for 72 h. The RNA was extracted using the RNeasy kit (Qiagen) according to manufacturer’s instructions. Preparation of cDNA, fragmentation and labeling was performed with the GeneChIPTM WT PLUS reagent kit (ThermoFisher Scientific). Samples were hybridized to the human Clariom™ S Assay (ThermoFisher Scientific).

Gene expression profiling of cell lines derived from classical Hodgkin lymphoma

Project description:Hodgkin lymphoma is derived from germinal center / post-germinal center B cells. To determine differentially expressed genes between Hodgkin Reed Sternberg cells and their presumed cell of origin we investigated the expression profiles of 5 commonly used Hodgkin lymphoma cell lines as compared to reactive germinal centers.

Tumor infiltrating HLA-matched CD4+ T cells retargeted against Hodgkin and Reed-Sternberg cells

Project description:Hodgkin's lymphoma (HL) is one of the most frequent hematological malignancies. Due to its extraordinary composition, few tumor cells surrounded by a reactive infiltrate, HL can be seen as an ideal model system for research focusing on tumor immunology. In fact, the tumor cells of HL, so called Hodgkin/Reed-Sternberg (HRS) cells attract CD4+ T cells, which then build rosettes with the HRS cells. HRS cells further modulate the tumor microenvironment with the help of CD4+ T cells to avoid tumor rejection. Here, we mimicked this scenario using compatible CD4+ T cells receiveing data of profound interactions for the first time, as former studies were performed with allogeneic donors. Finally, we genetically retargeted compatible CD4+ T cells to kill HRS cells.

Fibroblasts in Nodular Sclerosing Classical Hodgkin Lymphoma Are Defined by a Specific Phenotype and Protect Tumor Cells From Brentuximab-Vedotin Induced Injury

Project description:Several studies have described a crosstalk between the tumour cells of cHL, the Hodgkin- and Reed-Sternberg (HRS) cells, and cancer-associated fibroblasts (CAF). However, to date a deep molecular characterization of these fibroblasts is lacking. Aim of the present study therefore was a comprehensive characterization of these fibroblasts.
