Abstract
Human BCL10 deficiency causes combined immunodeficiency with bone marrow transplantation as its only curative option. To date, there are four homozygous mutations described in the literature that were identified in four unrelated patients. Here, we describe a fifth patient with a novel mutation and summarize what we have learned about BCL10 deficiency. Due to the severity of the disease, accurate knowledge of its clinical and immunological characteristics is instrumental for early diagnosis and adequate clinical management of the patients.

Genetic errors of the human caspase recruitment domain-B-cell lymphoma 10-mucosa-associated lymphoid tissue lymphoma-translocation gene 1 (CBM) complex: Molecular, immunologic, and clinical heterogeneity. J Allergy Clin Immunol 2015; 136:1139-49. [PMID: 26277595 DOI: 10.1016/j.jaci.2015.06.031] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2015] [Revised: 06/02/2015] [Accepted: 06/12/2015] [Indexed: 12/15/2022]
Abstract
Three members of the caspase recruitment domain (CARD) family of adaptors (CARD9, CARD10, and CARD11) are known to form heterotrimers with B-cell lymphoma 10 (BCL10) and mucosa-associated lymphoid tissue lymphoma-translocation gene 1 (MALT1). These 3 CARD-BCL10-MALT1 (CBM) complexes activate nuclear factor κB in both the innate and adaptive arms of immunity. Human inherited defects of the 3 components of the CBM complex, including the 2 adaptors CARD9 and CARD11 and the 2 core components BCL10 and MALT1, have recently been reported. Biallelic loss-of-function mutant alleles underlie several different immunologic and clinical phenotypes, which can be assigned to 2 distinct categories. Isolated invasive fungal infections of unclear cellular basis are associated with CARD9 deficiency, whereas a broad range of clinical manifestations, including those characteristic of T- and B-lymphocyte defects, are associated with CARD11, MALT1, and BCL10 deficiencies. Interestingly, human subjects with these mutations have some features in common with the corresponding knockout mice, but other features are different between human subjects and mice. Moreover, germline and somatic gain-of-function mutations of MALT1, BCL10, and CARD11 have also been found in patients with other lymphoproliferative disorders. This broad range of germline and somatic CBM lesions, including loss-of-function and gain-of-function mutations, highlights the contribution of each of the components of the CBM complex to human immunity.

Abstract
AIM: To assess the significance of chromosome translocation t(11;18)(q21;q21), B-cell lymphoma 10 (BCL-10) protein and Helicobacter pylori (H. pylori) infection in gastric mucosa-associated lymphoid tissue (MALT) lymphoma in Colombia.
METHODS: Fifty cases of gastric MALT lymphoma and their respective post-treatment follow-up biopsies were examined to assess the presence of the translocation t(11;18)(q21;q21) as identified by fluorescence in situ hybridization; to detect protein expression patterns of BCL10 using immunohistochemistry; and for evaluation of tumor histology to determine the correlation of these factors and resistance to H. pylori eradication.
RESULTS: Infection with H. pylori was confirmed in all cases of gastric MALT lymphoma in association with chronic gastritis. Bacterial eradication led to tumor regression in 66% of cases. The translocation t(11;18)(q21;q21) was not present in any of these cases, nor was there evidence of tumor transformation to diffuse large B-cell lymphoma. Thirty-four percent of the patients showed resistance to tumor regression, and within this group, 7 cases, representing 14% of all those analyzed, were considered to be t(11;18)(q21;q21)-positive gastric MALT lymphomas. Protein expression of BCL10 in the nucleus was associated with the presence of translocation and treatment resistance. Cases that were considered unresponsive to therapy were histologically characterized by the presence of homogeneous tumor cells and a lack of plasmacytic differentiation. Responder cases exhibited higher cellular heterogeneity and a greater frequency of plasma cells.
CONCLUSION: Both t(11;18)(q21;q21)-positive MALT lymphoma cases and those with nuclear BCL10 expression are considered resistant to H. pylori eradication. It is suggested that chronic antigenic stimulation is not a dominant event in resistant cases.

Abstract
Lunasin is a novel peptide from soybean with demonstrated chemopreventive property. We compared the effect of lunasin on gene expression of RAW 264.7 macrophages with and without lipopolysaccharide (LPS)-stimulation. Our hypothesis was that lunasin will have a differential effect in RAW 264.7 gene expression in a normal and challenged state. Analysis of the microarray data using False Discovery Rate (FDR) method resulted in the identification of 340 up-regulated and 162 down-regulated genes (FDR p-value <0.05) associated with simultaneous treatment of lunasin and LPS for 24h. Treatment of lunasin with no LPS for 24h resulted in the up-regulation of 855 genes and down-regulation of 397 genes. Pre-treatment of lunasin for 24h resulted in the up-regulation of 35 genes and down-regulation of 65 genes in LPS-stimulated RAW 264.7 macrophages. GeneVenn analysis of these three sets of genes showed that there are 66 genes common among the three groups which are mostly associated with regulation of cell death, ion binding and transcription as datamined by DAVID. Analysis of the 838 genes unique to lunasin alone by functional annotation clustering tool showed that lunasin mostly affected genes associated with RNA processing, apoptosis and protein kinase activity. Further datamining of these genes by ingenuity pathway analysis (IPA) showed that lunasin affected genes involved in cellular growth and proliferation, cellular function and maintenance, and cell to cell signaling and interaction. These findings support the potential chemopreventive and chemotherapeutic use of lunasin against cancer.

Abstract
A 70-yr-old woman was hospitalized with a history of dry cough. Bronchial endoscopy and transbronchial lung biopsy were performed. However, the findings of histopathology and immunohistochemistry were not sufficient to decide whether the lesion was benign or malignant, because of the presence of crush artifacts in the biopsy specimens. We performed B-cell clonality studies using BIOMED-2 multiplex PCR (InVivoScribe Technologies, USA) to detect clonal rearrangements in the immunoglobulin gene. The results of multiplex PCR showed clonal rearrangements of both kappa and lambda immunoglobulin light chain genes. The findings of immunochemistry revealed that the lesion expressed lambda light chain, but not kappa light chain. Based on the clinical, pathologic, and molecular findings, this case was diagnosed as pulmonary MALT lymphoma. We report the first case in Korea of lambda-expressing MALT lymphoma that is shown to have dual clonal rearrangements of kappa and lambda immunoglobulin light chain gene by multiplex PCR.

Abstract
In most H. pylori-positive patients, gastric low-grade mucosa-associated lymphoid tissue (MALT) lymphomas regress both endoscopically and histopathologically after H. pylori eradication, but no factors that can be predictive of the response to the eradication have been definitively identified, and there is little information on how to determine the optimal observation period before additional treatment can be started. Here, clinical studies dealing with the diagnosis and treatment of gastric MALT lymphomas and H. pylori published during the last 5 years were systematically reviewed, and studies identifying the molecular approaches involved in the pathogenesis were summarized. Most of the clinical studies indicate a favorable effect of H. pylori eradication on the clinical outcome of gastric MALT lymphomas. Some studies suggest the necessity of additional treatment in nonresponders to H. pylori eradication, while others suggest the adoption of a watch-and-wait strategy. The molecular characteristics of MALT lymphomas could play an important role in prognostic prediction and the selection of further therapeutic intervention after the eradication. This updated review of gastric MALT lymphomas illustrates the potential efficacy of H. pylori eradication in tumor remission, but further molecular characterization is necessary to establish the most suitable therapeutic strategy for patients who do not respond to eradication.

Abstract
PURPOSE The well-known translocations identified in MALT lymphomas include t(11;18)/API2-MALT1, t(1;14)/IGH-BCL10, and t(14;18)/IGH-MALT1. Molecular investigations have suggested that these three disparate translocations affect a common pathway, resulting in the constitutive activation of nuclear factor-kappaB. However, the vast majority of MALT lymphomas are negative for any of the above-mentioned translocations and the underlying pathogenesis is unclear. EXPERIMENTAL DESIGN Fresh tissue of 29 gastric and extragastric MALT lymphomas was studied for genetic aberrations by conventional karyotyping, long-distance inverse PCR (LDI-PCR), fluorescence in situ hybridization (FISH), reverse transcription-PCR (RT-PCR), and real-time quantitative RT-PCR (QRT-PCR). RESULTS Conventional cytogenetics, FISH, and RT-PCR identified aberrations in 26 of 29 MALT lymphoma. Balanced translocations were found in 21 cases. IGH was rearranged in the majority of cases with balanced translocations (n = 17/21); 3 cases had t(11;18)/API2-MALT1 and 1 case had novel t(6;7)(q25;q11), respectively. IGH partner genes involved MALT1, FOXP1, BCL6, and four new chromosomal regions on chromosome arms 1p, 1q, 5q, and 9p. LDI-PCR identified three novel partner genes on 1p (CNN3), 5q (ODZ2), and 9p (JMJD2C). FISH assays were established and confirmed LDI-PCR results. QRT-PCR showed deregulation of the novel genes in the translocation-positive cases. CONCLUSIONS Our study expands the knowledge on the genetic heterogeneity of MALT lymphomas.

Abstract
The purpose of this study is to identify genes that are involved in the etiology of Helicobacter pylori induced gastric MALT lymphoma. We compared gene expression profiles of gastric MALT lymphoma with their corresponding gastric MALT (chronic gastritis with formation of follicles and aggregates). cDNA microarrays were used to compare these two tissue types from the same patient (n = 21). Quantitative PCR and immunohistochemical staining were performed to validate the microarray results. Three hundred and fifty eight out of 11,552 genes were differentially expressed between gastric MALT lymphomas and gastric MALT. Thirty eight genes are implicated in immune response, 66 in signal transduction and 36 in cell proliferation. Interestingly, chromosome 6 was the only chromosome which was significantly over-represented with 25 genes (EASE score p = 0.01254). Several surface markers of haematopoietic cells, such as CD1c, CD40, CD44, CD53, CD83, CD86 and members of the HLA-D family were up-regulated in lymphoma tissues, indicating antigen-dependent survival of lymphoma cells. We conclude that gastric MALT lymphoma shows a specific gene expression profile, which allows the differentiation from H. pylori induced lymphoid gastritis.

Abstract
The genomic aberrations in extra nodal marginal zone B cell lymphoma vary according to their anatomical origin. This polarization is a reflection of the participation of different genes in the lymphomagenesis of marginal zone B cell lymphoma. We previously demonstrated by means of genome-wide array comparative genomic hybridization (CGH) that the genomic profile of ocular adnexal marginal zone B cell lymphoma is distinct from that of pulmonary or nodal marginal zone B cell lymphoma. The novel finding was a recurrent deletion of a 2.9-Mb region at chromosome band 6q23.3-q24.1, including homozygous loss, in ocular adnexal marginal zone B cell lymphoma. For a more detailed examination of the deletions of 6q23.3-24.1, we used contig bacterial artificial chromosome (BAC) array CGH, containing 24 BAC clones covering the 2.9-Mb region, to analyze nine cases with 6q23.3-q24.1 loss. We narrowed the minimal common region down to a length of 586 kb with two genes and four expressed sequence tags (ESTs). All of these genes and ESTs were subjected to RT-PCR and real-time quantitative RT-PCR. Correlation between genomic loss and expression level was found only for TNFAIP3, demonstrating that TNFAIP3 is a target gene of 6q deletion in ocular adnexal marginal zone B cell lymphoma. TNFAIP3 is an inhibitor of NF-kB signaling so that loss of this gene may play an important role in lymphomagenesis and suggests that TNFAIP3 may act as a tumor suppressor gene in ocular adnexal marginal zone B cell lymphoma.

Abstract
Genetic immunization (GI), which is primarily used for vaccine purposes, is a method for producing antibodies to a protein by delivering the gene encoding the protein as a eukaryotic expression vector instead of the protein itself. The mucosa-associated lymphoid tissue lymphoma translocation gene 1 (MALT1) is one of the most likely candidates for involvement in pathogenesis of MALT lymphoma and probably of multiple myelomas. In the present work we describe the production and characterization of a mouse monoclonal antibody (mAb) directed against MALT1 and the study of MALT1 protein expression in a large series of lymphomas and myeloma cell lines. The full-length coding sequence of human MALT1 was inserted into pcDNA3 vector and delivered into mouse skin using a helium gene gun. Six new mAbs against the MALT1 molecule were produced. In order to characterize and confirm the specificity of these mAbs, Western blot (WB) and immunoprecipitation (IP) analyses were performed. A new anti-MALT1 mAb was selected and tested in a large series of cell lines. These results confirm that GI is a reliable and effective alternative method for production of mAbs, allowing accurate and sensitive detection and screening of proteins by WB.

Abstract
Activation of the transcription factor nuclear factor (NF)-kappaB is essential for the normal functioning of the immune system. Deregulated NF-kappaB signalling in lymphocytes can lead to immunodeficiency, but also to autoimmunity or lymphomas. Many of the signalling components controlling NF-kappaB activation in lymphocytes are now known, but it is less clear how distinct molecular components of this pathway are regulated. Here, we summarize recent findings on post-translational modifications of intracellular components of this pathway. Phosphorylation of the CARMA1 and BCL10 proteins and ubiquitylation of BCL10 affect the formation and stability of the CARMA1-BCL10-MALT1 (CBM) complex, and also control negative feedback regulation of the NF-kappaB signalling pathway. Moreover, the study of BCL10 phosphorylation isoforms has revealed a new mechanism controlling BCL10 nuclear translocation and an unexpected role for BCL10 in the regulation of the actin cytoskeleton.
