PURPOSE: Extranodal natural killer/T-cell lymphoma (ENKTL), nasal-type, is a distinct subtype of non-Hodgkin lymphoma. ENKTL is sensitive to radiotherapy, but the prognosis is poorer than those of other types of early stage lymphoma. To date, optimal treatment strategies for patients with early stage ENKTL have not been fully defined. METHODS: We retrospectively investigated the efficacy and safety of pegaspargase, gemcitabine, and oxaliplatin (P-GEMOX) combined with different dose radiotherapy (RT) in the treatment of 35 newly diagnosed, stage IE to IIE ENKTL patients at our institution from October 2011 to September 2015...

BACKGROUND: Recent studies have suggested that latent herpes virus infections can be associated with chronic periodontal sites that exhibit a predisposition to disease progression. The aim of this study was to identify the possible relationship between infections with CMV and EBV and the severity of periodontal disease. MATERIALS AND METHODS: Fifty two patients aged between 27 and 70 years, diagnosed with periodontal disease were enrolled in the study after giving informed consent...

A 41-year-old man was referred to our hospital for treatment of anaplastic lymphoma kinase (ALK)-negative anaplastic large cell lymphoma. Chronic active Epstein-Barr virus (CAEBV) was diagnosed based on the findings of elevated EBV antibody titers and positive EBV-DNA in the peripheral blood, and cord blood stem cell transplantation (CBT) was performed. The EBV-DNA levels in the blood fell below the limit of detection. His lymphoma relapsed on Day 165 with the appearance of eruptions, which disappeared after the withdrawal of tacrolimus...

Cancer-initiating cells (CICs) are specialized cells that have the ability to self-renew and are multipotent. We recently demonstrated that Forkhead box O3a (FoxO3a)-expressing cells exhibited a CIC-like potential in Hodgkin's lymphoma (HL). A proportion of HL patients are infected with Epstein-Barr virus (EBV). EBV-encoded latent membrane protein (LMP) 1 downregulates FoxO3a, suggesting that FoxO3a expression may be abolished in EBV-positive HL. Inhibitors of DNA-binding (ID) proteins are highly conserved transcription factors mediating stem cell functions...

We introduce an innovative approach to lowering the overall cost of obtaining genomic EBV (GEBV) and encourage their use in commercial extensive herds of Brahman beef cattle. In our approach, the DNA genotyping of cow herds from 2 independent properties was performed using a high-density bovine SNP chip on DNA from pooled blood samples, grouped according to the result of a pregnancy test following their first and second joining opportunities. For the DNA pooling strategy, 15 to 28 blood samples from the same phenotype and contemporary group were allocated to pools...

PURPOSE: In patients with Epstein-Barr virus (EBV)-associated nasopharyngeal carcinoma (NPC), intertumor heterogeneity causes interpatient heterogeneity in the risk of distant metastasis. We aimed to identify novel biomarkers of metastasis risk using reverse-phase protein array (RPPA) profiling of NPC patients at risk for metastasis and considering plasma EBV DNA load. EXPERIMENTAL DESIGN: A total of 98 patients with NPC with and without metastasis after treatment, matched with respect to clinical parameters, were enrolled...

Determining which components of the transcription machinery associate with the viral and cellular genome, and how this changes at specific stages of the viral life cycle is paramount to understanding how the distinct transcriptional programs associated with primary infection, latency, and disease are established and how they are reprogrammed during initiation and execution of the viral lytic replication cycle. Chromatin precipitations linked to next generation DNA sequencing (ChIP-Seq) allow for the interactions of proteins with DNA to be mapped across both viral and cellular genomes...

DNA sequencing approaches originally developed in two directions, the chemical degradation method and the chain-termination method. The latter one became more widespread and a huge amount of sequencing data including whole genome sequences accumulated, based on the use of capillary sequencer systems and the application of a modified chain-termination method which proved to be relatively easy, fast, and reliable. In addition, relatively long, up to 1000 bp sequences could be obtained with a single read with high per-base accuracy...

Epstein-Barr virus (EBV) was the first human virus associated directly with human malignancies. During EBV infection of various host cells the double-stranded linear EBV DNA carried by the virions undergoes circularization. Since there are variable numbers of terminal repetitions (TRs) at the ends of the linear EBV genome, the resulting circular episomes enclose a variable number of TRs. Thus, in cells carrying viral episomes, the sizes of the terminal restriction enzyme fragments of EBV is affected by the number of TRs (Raab-Traub and Flynn Cell 47:883-889, 1986)...

The vast majority of the human adult population is infected with Epstein-Barr virus (EBV), and the majority of the EBV-infected individuals tolerates the infection well, without any further symptoms after primary infection. In cases of individuals which undergo primary infection in the form of an infectious mononucleosis, or which have undergone primary infection in their past, it is sometimes important to appraise symptomatic disease or differentiate infectious mononucleosis from other conditions. In these cases, serological methods, i...

Epstein-Barr virus (EBV) is associated with the pathogenesis of several diseases in both adults and children. However, there have been no reports on the prevalence and amount of EBV in the adenoids of adults; thus, it is important to investigate these in the adenoids and tonsils of adults and children. In this study, 67 patients who underwent tonsillectomy or adenotonsillectomy were included and divided into two groups: adults aged ≥ 16 years (n = 35) and children aged <16 years (n = 32). Patients' adenoid and tonsil tissues were analyzed using quantitative polymerase chain reaction for EBV DNA...

We analyzed CpG-island hypermethylation status in 12 genes of paraffin-embedded tissues from 38 rheumatoid arthritis (RA) patients with methotrexate (MTX)-associated large B cell lymphoproliferative disorder (BLPD), 11 RA patients with non-MTX-associated BLPD (non-MTX-BLPD), 22 controls with diffuse large B cell lymphoma (DLBCL), and 10 controls with Epstein-Barr virus (EBV)(+) DLBCL. Among them, tumor cells from EBV(+) MTX-BLPD patients and control EBV(+) DLBCL patients had significantly lower median incidence of CpG island methylator phenotype (CIMP) than those from non-MTX-BLPD and control DLBCL groups (2...

Infectious agents have been identified as a major cause of specific types of human cancers worldwide. Several microorganisms have been identified as potential aggravators of ocular adnexal neoplasms; however, given the rarity of these neoplasms, large epidemiological studies are difficult to coordinate. This study aimed to conduct an exhaustive search for pathogenic DNA in lymphoproliferative disorders (LPD) of the ocular adnexa in a total of 70 patients who were diagnosed with LPD of the ocular adnexa between 2008 and 2013...

Extensive DNA methylation is observed in gastric cancer with Epstein-Barr virus (EBV) infection, and EBV infection is the cause to induce this extensive hypermethylaton phenotype in gastric epithelial cells. However, some 5' regions of genes do not undergo de novo methylation, despite the induction of methylation in surrounding regions, suggesting the existence of a resistance factor against DNA methylation acquisition. We conducted an RNA-seq analysis of gastric epithelial cells with and without EBV infection and found that TET family genes, especially TET2, were repressed by EBV infection at both mRNA and protein levels...

BACKGROUND: The prevalence of HCV infection in people with hemophilia is substantially higher than that in the general population (63% - 98%). Multiple transfusions and substitutive therapy have also been linked to a high risk of HBV and HIV transmission. However, the prevalence of other blood-borne viral infections in this population is less well known. OBJECTIVES: This study aimed to assess the prevalence of co-infection with HBV and other blood-borne viruses in Polish HCV-infected hemophiliacs...

We describe the establishment and characterization of a cell line, AM-HLH, obtained from a patient with Epstein-Barr virus-positive (EBV(+) ) nodular sclerosis-type Hodgkin lymphoma (HL). The cells were positive for CD2 and CD30 and negative for CD15. The immunoglobulin heavy- and κ light-chain genes were rearranged. The karyotype was of the triploid range. Southern blotting using the EBV terminal repeat probe detected 3 hybridizing bands that were identical to those of the parental HL material. The cells expressed EBV-encoded RNAs as well as latent genes (EBNA1, EBNA2, LMP1, and LMP2A) and lytic genes (BZLF1 and BALF2)...

Most nasopharyngeal carcinomas (NPCs) in a high-incidence population are driven by Epstein-Barr virus (EBV) infection. EBV-associated malignancies have increased expression of the programmed death-ligand 1 (PD-L1). Immunotherapy agents targeting the PD-1/PD-L1 pathway have achieved durable treatment effects in patients with various cancer types including EBV-associated malignancies. In this study, we sought to investigate PD-L1 expression in a cohort of patients with NPCs from the Philippines. Fifty-six NPCs were studied for PD-L1, p16, and DNA mismatch repair (MMR) deficiency by immunohistochemistry...

BACKGROUND: Hemophagocytic lymphohistiocytosis (HLH) is a life threatening hematological disorder associated with severe systemic inflammation caused by an uncontrolled and ineffective immune response resulting in cytokine storm. Epstein-Barr virus (EBV) is the most common infectious agent in patients with the viral-associated HLH. Limited numbers of cases with cardiac complication have been demonstrated in other viral-associated HLH patients. Herein, we report a pediatric case of severe EBV-associated HLH with cardiac complications...
