Abstract
Epstein-Barr Virus (EBV) infects more than 90% of the adult population worldwide. EBV infection is associated with Burkitt lymphoma (BL) though alone is not sufficient to induce carcinogenesis implying the involvement of co-factors. BL is endemic in African regions faced with mycotoxins exposure. Exposure to mycotoxins and oncogenic viruses has been shown to increase cancer risks partly through the deregulation of the immune response. A recent transcriptome profiling of B cells exposed to aflatoxin B1 (AFB1) revealed an upregulation of the Chemokine ligand 22 (CCL22) expression although the underlying mechanisms were not investigated. Here, we tested whether mycotoxins and EBV exposure may together contribute to endemic BL (eBL) carcinogenesis via immunomodulatory mechanisms involving CCL22. Our results revealed that B cells exposure to AFB1 and EBV synergistically stimulated CCL22 secretion via the activation of Nuclear Factor-kappa B pathway. By expressing EBV latent genes in B cells, we revealed that elevated levels of CCL22 result not only from the expression of the latent membrane protein LMP1 as previously reported but also from the expression of other viral latent genes. Importantly, CCL22 overexpression resulting from AFB1-exposure in vitro increased EBV infection through the activation of phosphoinositide-3-kinase pathway. Moreover, inhibiting CCL22 in vitro and in humanized mice in vivo limited EBV infection and decreased viral genes expression, supporting the notion that CCL22 overexpression plays an important role in B cell infection. These findings unravel new mechanisms that may underpin eBL development and identify novel pathways that can be targeted in drug development.

Liu F, Tian S, Liu Q, Deng Y, He Q, Shi Q, Chen G, Xu X, Yuan J, Nakamura S, Karube K, Wang Z. Comparison of genomic alterations in Epstein-Barr virus-positive and Epstein-Barr virus-negative diffuse large B-cell lymphoma. Cancer Med 2024; 13:e6995. [PMID: 38457199 PMCID: PMC10922027 DOI: 10.1002/cam4.6995] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 12/30/2023] [Accepted: 01/26/2024] [Indexed: 03/09/2024] Open
Abstract
BACKGROUND Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (EBV-posDLBCL) is an aggressive B-cell lymphoma that often presents similar morphological and immune phenotype features to that of EBV-negative DLBCL (EBV-negDLBCL). AIMS AND METHODS To better understand their difference in genomic landscape, we performed whole-exome sequencing (WES) of EBV-posDLBCL and EBV-negDLBCL. RESULTS This analysis revealed a new mutational signature 17 (unknown) and signature 29 (smoking) in EBV-posDLBCL as well as a specific mutational signature 24 (associated with aflatoxin) in EBV-negDLBCL. Compared with EBV-negDLBCL, more somatic copy number alterations (CNAs) and deletions were detected in EBV-posDLBCL (p = 0.01). The most frequent CNAs specifically detected in EBV-posDLBCL were gains at 9p24.1 (PDL1 and JAK2), 8q22.2-q24.23 (DEPTOR and MYC), and 7q31.31-q32.2 (MET), which were validated in additional EBV-posDLBCL cases. Overall, 53.7% (22/41) and 62.9% (22/35) of the cases expressed PD-L1 and c-MET, respectively, in neoplastic cells, whereas only 15.4% (4/26) expressed c-MYC. Neoplastic c-MET expression was positively correlated with PD-L1 (p < 0.001) and MYC expression (p = 0.016). However, EBV-posDLBCL cases did not show any differences in overall survival between PD-L1-, c-MET-, or c-MYC-positive and -negative cases or between age-related groups. Analysis of the association between somatic mutation load and EBV status showed no difference in the distribution of tumor mutant burden between the two lymphomas (p = 0.41). Recurrent mutations in EBV-posDLBCL implicated several genes, including DCAF8L1, KLF2, and NOL9, while in EBV-negDLBCL, ANK2, BPTF, and CNIH3 were more frequently mutated. Additionally, PIM1 is the most altered gene in all the WES-detected cases. CONCLUSIONS Our results confirm that genomic alteration differs significantly between EBV-posDLBCL and EBV-negDLBCL, and reveal new genetic alterations in EBV-posDLBCL. The positive correlation of c-MET and PD-L1/c-Myc expression may be involved in the pathogenesis of EBV-posDLBCL, which is should be explored prospectively in trials involving MET-directed therapies.

Acta Histochem 2024; 126:152116. [PMID: 38101290 DOI: 10.1016/j.acthis.2023.152116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 11/08/2023] [Accepted: 11/13/2023] [Indexed: 12/17/2023]
Abstract
INTRODUCTION The combined pathogenesis of Aflatoxin B1 (AFB1) and several viruses such as HBV, EBV and influenza virus have been investigated yet the molecular mechanism of their interaction and possible synergistic effects is not fully understood. OBJECTIVES The aim of the current systematic review was to review in-vitro and in-vivo studies investigating the combined pathogenesis of aflatoxins and viruses. METHODS This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. PECO (Population, Exposure, Comparator, and Outcome) criteria for invitro and invivo studies were used to evaluate the eligibility of the studies for systematic review. RESULTS 21 studies were eligible for qualitative analysis based on the inclusion criteria. Of all the included studies, 9 (42.9 %) were invivo, 7 (33.3 %) were invitro-invivo and 5(23.8) articles conducted only invitro assay. Furthermore 14 (66.6 %) article explored hepatitis B virus (HBV) combination with AFB1, 4 (19 %) studied influenza A virus (SIV), 2 (9.7 %) were about Epstein-Barr virus (EBV) and only 1 (4.7 %) included hepatitis C virus (HCV). CONCLUSION The limited collected evidence suggests that AFB1 enhanced EBV and influenza virus pathogenesis. AFB1 also operated as a cofactor for HBV and EBV-mediated carcinogenesis. On the other hand HBV and HCV also induced AFB-1 carcinogenesis. Due to the limited amount of included studies and the inconsistency of their results further studies especially on HBV and SIV are essential for better understanding of their combined mechanisms.
