Project description:Coxiella burnetii, the agent causing Q fever, has been associated with B-cell non-Hodgkin lymphoma (NHL). To better clarify this link, we analysed the genetic transcriptomic profile of peripheral blood leukocytes from patients with C. burnetii infection to identify possible links to lymphoma. Microarray analyses revealed that 1189 genes were expressed differently (p <.001 and fold change ≥4) in whole blood of patients with C. burnetii infection compared to controls. In addition, 95 genes expressed in patients with non-Hodgkin lymphoma (NHL) and in patients with C. burnetii persistent infection have allowed us to establish the ‘C. burnetii-associated NHL signature’. Among these, 33 genes previously found modulated in C. burnetii-associated -NHL by the microarray analysis were selected and their mRNA expression levels were measured in distinct C. burnetii-induced pathologies, namely, acute Q fever, focalized persistent infection, lymphadenitis and C.burnetii-associated NHL. Specific genes involved in anti-apoptotic process were found highly expressed in leukocytes from patients with C. burnetii associated-NHL: MIR17HG, REL and SP100. This signature differed from that found for NHL-control group. Patients with C. burnetii lymphadenitis presented significant elevated levels of BCL2 and ETS1 mRNAs. Altogether, we identified a specific transcriptionnal signature for NHL during C. burnetii infection reflecting the up-regulation of anti-apoptotic processes and the fact that lymphadenitis might constitute a critical step towards lymphomagenesis.

Project description:Non-Hodgkin lymphomas (NHL) make up the majority of lymphoma diagnoses and represent a very diverse set of malignancies. We sought to identify kinases uniquely upregulated in different NHL subtypes. Using Multiplexed Inhibitor Bead-mass spectrometry (MIB/MS), we found Tyro3 was uniquely upregulated and important for cell survival in primary effusion lymphoma (PEL), which is a viral lymphoma infected with Kaposi’s sarcoma-associated herpesvirus (KSHV).

Project description:This series represents the data set of Array CGH from the paper (submit for publication): “Homozygous deletions localize novel tumor suppressor genes in B-cell lymphomas. Mestre et all. ” and it's web supplement. The molecular nature of many secondary events in the pathogenesis of B-cell non Hodgkin lymphoma (B-NHL) remains unknown. We used high-resolution CGH to BAC microarrays to characterize the genomes of 48 B-cell non-Hodgkin lymphoma (B-NHL) cell lines of different origins. Array CGH identified, on average, 20 genomic alterations per cell line, including regional gains and losses as well as previously uncharacterized aberrations. Different genomic patterns were observed among the B-NHL subtypes. To search for possible oncogenic target genes, gene expression profiling was performed in the cell lines models. Integrative genomic and gene expression analyses have identified amplified oncogenes in B-cell non-Hodgkin lymphoma (B-NHL), but the capability of such technologies to localize tumor suppressor genes within homozygous deletions remains unexplored. Array-based comparative genomic hybridization (CGH) and gene expression microarray analysis of 48 cell lines derived from patients with different B-NHLs delineated twenty homozygous deletions at seven chromosome areas, all of which contained tumor suppressor gene targets. Further investigation revealed that only a fraction of primary biopsies presented inactivation of these genes by point mutation or intragenic deletion, but instead some of them were frequently silenced by epigenetic mechanisms. Our microarray strategy has identified novel candidate suppressors inactivated by genetic and epigenetic mechanisms that substantially vary among the B-NHL subtypes.

Project description:The redirection of T-cells has emerged as an attractive therapeutic principle in B-cell non-Hodgkin lymphoma (B-NHL). However, a detailed characterization of lymphoma-infiltrating T-cells across B-NHL entities is missing. Here, we present cellular indexing of transcriptomes and epitopes of lymph-node derived T-cells from patients with diffuse large B-cell, mantle cell, follicular, or marginal zone lymphoma, and from healthy controls. These data revealed quantitative aberrations of the T-cell microenvironment across and within B-NHL entities.

However, a detailed characterization of lymphoma-infiltrating T-cells across B-NHL entities is missing. Here, we present single-cell transcriptome and T-cell receptor sequencing of lymph-node derived T-cells from patients with diffuse large B-cell, mantle cell, follicular, or marginal zone lymphoma, and from healthy controls. These data revealed quantitative aberrations of the T-cell microenvironment across and within B-NHL entities.
