Global genomic studies have detected the role of genomic alterations in the pathogenesis of Epstein–Barr virus (EBV)-associated tumors. EBV oncoproteins cause a vital shift of EBV from an infectious virus to an oncogenic form during the latent and lytic phase within the lymphoid B cells and epithelial cells. This epigenetic alteration modulates the virus and host genomes and inactivates and disrupts numerous tumor suppressors and signaling pathways. Genomic profiling has played the main role in identifying EBV cancer pathogenesis and its related targeted therapies. This article reviews the role of genetic changes in EBV-associated lymphomas and carcinomas. This includes the prolific molecular genesis, key diagnostic tools, and target-specific drugs that have been in recent clinical use.

Background For long Epstein–Barr virus (EBV) has been suspected to be involved in the pathogenesis of systemic lupus erythematosus (SLE). The aim of this study was to verify the association between EBV, cell-free DNA (cfDNA) and kidney disease in SLE. Methods Blood samples were obtained from 43 SLE patients and 50 healthy individuals. EBV load was measured via real-time PCR assay. Sizing and quantification of plasma cfDNA was performed on Bioanalyzer. We proposed that the uniformity of cfDNA fragmentation can be described using cfDNA fragmentation index. Results SLE patients with chronic kidney disease (CKD +) had higher EBV load compared to CKD(–) patients (P = 0.042). Patients with high cfDNA level had higher EBV load (P = 0.041) and higher cfDNA fragmentation index (P < 0.001) compared to patients with low cfDNA level. Among patients with high cfDNA level, EBV load was higher in CKD(+) group compared to CKD(–) group (P = 0.035). EBV load was positively correlated with the fragmentation index in all SLE patients (P = 0.028, R2 = 0.13), and the correlation was even more pronounced in CKD (+) patients (P < 0.001, R2 = 0.20). Conclusions We showed that EBV load was associated with non-uniform cfDNA fragmentation, higher cfDNA levels, and kidney disease in SLE patients. Although the causality of this relationship could not be determined with the current study, it brings rationale for further investigations on the role of EBV and cfDNA interplay in SLE pathogenesis.

USP7 (also called HAUSP) is a de-ubiquitinating enzyme recently identified as a key regulator of the p53–mdm2 pathway, which stabilizes both p53 and mdm2. We have discovered that the Epstein–Barr nuclear antigen 1 protein of Epstein–Barr virus binds with high affinity to USP7 and disrupts the USP7–p53 interaction. The results have important implications for the role of Epstein–Barr nuclear antigen 1 in the cellular immortalization that is typical of an Epstein–Barr virus latent infection.

Introduction: Post-transplant lymphoproliferations (PTL) are a severe complication of solid organ transplants. Their locations can be extra-nodal. Observation: The diagnosis and management of a non-Hodgkin's plasmablastic lymphoma of mandibular localization affecting a 66-year-old kidney transplanted patient are reported here. Comment: The main risk factors for non-Hodgkin lymphoma are immunosuppression and infection with Epstein-Barr virus. Clinical and radiographic examinations, which are not specific, must be supplemented by a histological examination. Treatment which is not consensual will most often consist of a reduction in immunosuppression coupled with chemotherapy. Conclusion: Despite a constant evolution in the incidence and clinical picture of post-transplant lymphomas, the role of the dentist remains essential in the early detection of lesions.
