[PMID: 36649009 PMCID: PMC9844464 DOI: 10.3390/pathophysiology30010001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2022] [Revised: 12/14/2022] [Accepted: 01/01/2023] [Indexed: 01/13/2023] Open
Abstract
Nasopharyngeal carcinoma (NPC) is the most common cancer among head and neck cancers in Vietnam. We aimed to identify the rate of a 30 bp deletion mutation of the LMP1-EBV gene in nasopharyngeal biopsy tissue samples, the HLA genotypes of NPC patients, and the relationship between these two targets. Patients with NPC at Can Tho Oncology Hospital from September 2014 to December 2018 were selected. A length of 30 bp of the del-LMP1-EBV gene was analyzed using a PCR technique, and the HLA genotypes in patients' blood samples were analyzed with PCR-SSO technology. HLA-B*15 gene carriers had the highest risk of 30 bp LMP1-EBV gene deletion mutation, which was found in 51 out of 70 patients (72.9%). Carriers of the HLA-B*15 allele had a 4.6-fold increased risk of a 30 bp del-LMP1-EBV gene compared with non-carriers of this allele. The initial identification of NPC was related to the 30 bp del-LMP1-EBV gene and high frequencies of the -A*02, -B*15, -DRB1*12, -DQB1*03, and -DQA1*01 HLA alleles. Our study results suggest an association of the 30 bp del-LMP1-EBV gene and the HLA-B*15 allele with NPC susceptibility.

Association between HLA alleles and Epstein-Barr virus Zta-IgA serological status in healthy males from southern China. J Gene Med 2021; 23:e3375. [PMID: 34164868 PMCID: PMC8596395 DOI: 10.1002/jgm.3375] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Accepted: 06/22/2021] [Indexed: 11/12/2022] Open
Abstract
Background Nasopharyngeal carcinoma (NPC), an Epstein–Barr virus (EBV) associated cancer, exhibits an extremely high incidence in southern Chinese. Given that human leukocyte antigen (HLA) plays critical roles in antigen presentation and relates to NPC susceptibility, it is speculated that certain HLA variants may affect EBV reactivation, which is a key pathogenic factor of NPC. Therefore, we attempted to identify HLA alleles associated with the indicator of EBV reactivation, Zta‐IgA, in healthy males from NPC endemic area. Methods HLA alleles of 1078 healthy males in southern China from the 21‐RCCP study were imputed using genome‐wide single nucleotide polymorphism data. EBV Zta‐IgA in blood samples were measured using an enzyme‐linked immunosorbent assay. Multiple logistic regression analysis was used to evaluate the effect of HLA allele on Zta‐IgA serological status and its potential joint association with smoking. The binding affinity for Zta‐peptide was predicted using NetMHCIIpan 4.0. Results HLA‐DRB1*09:01 was found to be associated with a higher risk of Zta‐IgA seropositivity (odds ratio = 1.80, 95% confidence interval = 1.32–2.45; p = 1.82 × 10−4). Compared with non‐smokers without HLA‐DRB1*09:01, the effect size increased to 2.19‐ and 3.70‐fold for the light and heavy smokers carrying HLA‐DRB1*09:01, respectively. Furthermore, HLA‐DRB1*09:01 showed a stronger binding affinity to Zta peptide than other HLA‐DRB1 alleles. Conclusions Our study highlighted the pivotal role of genetic HLA variants in EBV reactivation and the etiology of NPC. Smokers with HLA‐DRB1*09:01 have a significantly higher risk of being Zta‐IgA seropositive, which indicates the necessity of smoking cessation in certain high‐risk populations and also provide clues for further research on the etiology of NPC.

Abstract
Background The incidence rate of nasopharyngeal carcinoma (NPC) has been documented to be high in Southeast Asia. Interleukin-18 (IL-18) is a multifunctional cytokine that augments interferon-γ production and acts as an important immunomediator in the development of several types of cancer. Patients and methods This case-control study evaluated the role of IL-18 in NPC at the DNA level by genotyping its promoter polymorphisms at positions -656, -607, and -137 in a Taiwanese population. A total of 176 patients with NPC and age- and gender-matched 352 noncancer controls were included in this study. Results The CC genotype of the IL-18-607 polymorphism was found to be associated with significantly decreased risks of NPC compared to the AA genotype (crude OR =0.50, 95% CI =0.29-0.84, P=0.0093). This significant difference persisted even in the dominant and recessive models. A significantly lower C allele frequency at position -607 was detected in the NPC group(41.8% vs 50.3%; OR =0.77; 95% CI =0.63-1.04, P=0.0089). Regarding IL-18-656 and -137 polymorphisms, there were no differential distributions of their genotypes between the NPC and control groups. After substratification of the subjects according to their smoking, alcohol consumption, and areca chewing status, the genotype distribution of the IL-18-607 polymorphism was found to be different only among nonsmokers between the NPC and control subgroups. Conclusion This study suggests that IL-18 plays an important role in the carcinogenesis of NPC in Taiwan and that the genotype-phenotype correlation of IL-18-607 polymorphism and its contribution to NPC need to be investigated further.

Abstract
Background: Development of innovative immunotherapy is imperative to improve the poor survival of the nasopharyngeal carcinoma (NPC) patients. In this study, we evaluated the T cell response to melanoma-associated antigen (MAGE)-A1, MAGE-A3, or synovial sarcoma X-2 (SSX-2) in the peripheral blood of treatment-naive NPC patients. The relationship of responses among the three proteins and the human leukocyte antigen (HLA)-A types were analyzed to provide evidence of designing novel therapy. Methods: Sixty-one NPC patients admitted into the Tumor Hospital affiliated to the Xinjiang Medical University between March 2015 and July 2016 were enrolled. Mononuclear cells were isolated from the peripheral blood before any treatment. HLA-A alleles were typed with Sanger sequence-based typing technique. The T cell response to the MAGE-A1, MAGE-A3, or SSX-2 was evaluated with the Enzyme-Linked ImmunoSpot assay. Mann-Whitney U-test was used to compare the T cell responses from different groups. Spearman's rank correlation was used to analyze the relationship of T cell responses. Results: HLA-A*02:01, A*02:07, and A*24:02 were the three most frequent alleles (18.9%, 12.3%, and 11.5%, respectively) among the 22 detected alleles. 31.1%, 19.7%, and 16.4% of the patients displayed MAGE-A1, MAGE-A3, or SSX-2-specific T cell response, respectively. The magnitudes of response to the three proteins were 32.5, 38.0, and 28.7 SFC/106 peripheral blood mononuclear cells, respectively. The T cell response against the three proteins correlated with each other to different extent. The percentage of A*02:01 and A*24:02 carriers were significantly higher in patients responding to any of the three proteins compared to the nonresponders. Conclusion: MAGE-A1, MAGE-A3, or SSX-2-specific T cell responses were detectable in a subgroup of NPC patients, the frequency and magnitude of which were correlated.

Abstract
Epidemiological studies have shown that human leukocyte antigen (HLA) allelic polymorphisms are closely correlated to susceptibility to nasopharyngeal carcinoma (NPC), and in a previous study, we showed that HLA-B*46 and HLA-A*02-B*46 haplotypes were strongly associated with NPC susceptibility. In this retrospective study, we investigated the phenotype of the HLA-A and HLA-B alleles and haplotypes and correlated these data to the clinical and pathological parameters of NPC to understand the role of HLA alleles and haplotypes in NPC prognosis. The cohort comprised 117 NPC patients from a Han population in Xinjiang. The local recurrence-free survival (LRFS), distant metastasis- free survival (DMFS), disease-free survival (DFS), and overall survival (OS) were analyzed. The 5-year DMFS of the HLA-A*02-B*46 haplotype carriers and non-carriers was 66.4% and 90.3%, respectively. In addition, age was found to be a prognostic factor for LRFS, DFS, and OS (P=0.032, 0.040, and 0.013, respectively). We found that the HLA-A*02-B*46 haplotype might be a prognostic marker in addition to the traditional TNM staging in patients with NPC.

Abstract
Background: Genetic susceptibility is one of the major etiological factors for nasopharyngeal carcinoma (NPC). Among the genetic predisposing factors, human leukocyte antigen (HLA) genes have been reported to be associated with NPC. This study aimed to investigate the associations of HLA-DRB1 alleles with NPC and the clinical significance of HLA-DRB1 alleles in NPC. Methods: From January 2009 to December 2013, 140 NPC patients (118 Han patients and 22 Uyghur patients) and 158 healthy controls (81 Han individuals and 77 Uyghur individuals) from Xinjiang Province were genotyped for HLA-DRB1 using the polymerase chain reaction-sequence specific primer technique. Chi-square analysis was used when comparing allele frequencies between groups. The clinical outcomes were evaluated by Kaplan-Meier method and Cox regression model. Results: Compared with healthy controls, the allele frequency of HLA-DRB1*0701 was increased in the Uyghur patients (P = 0.008) but not in the Han patients (P = 0.869). HLA-DRB1*0101 allele was presented with higher frequency in clinical Stage I + II group compared with clinical Stage III + IV group in the Han patients (P = 0.015) but not in the Uyghur patients (P = 1.000). Higher frequency of HLA-DRB1*1501 allele was observed in patients aged <45 years compared with those in patients aged ≥45 years (P = 0.002). Neither HLA-DRB1*0701 nor HLA-DRB1*0101 had a statistically significant association with 3-year survival. Conclusions: This study found HLA-DRB1*0701 in Uyghur population was associated with an increased risk of developing NPC. In Han population, we found HLA-DRB1*0101 was associated with protection from disease progression, and HLA-DRB1*1501 was associated with early age of onset. HLA-DRB1 could not be identified as a prognostic indicator for NPC in either Han or Uyghur patients.

Abstract
Human leukocyte antigen (HLA)-DRB1 has been reported to influence individual's susceptibility to nasopharyngeal carcinoma (NPC) by many studies in recent years; however, these studies provided controversial results. The meta-analysis was thus conducted here to estimate the relationship between HLA-DRB1 polymorphisms and NPC. After an extensive review of journals from various databases (PubMed, the Web of Science, Embase, China National Knowledge Internet (CNKI), and Wanfang Database), 8 out of 69 case-control studies, including 778 cases and 1148 controls, were extracted. The results showed that 4 of 13 polymorphisms allele are statistically significantly associated with NPC, among them, HLA-DRB1*3, HLA-DRB1*9, and HLA-DRB1*10 may increase the risk of NPC while HLA-DRB1*01 has the opposite effect. The pooled odds ratio and 95 % confidence interval (CI) were 1.702 [95 % CI (1.047, 2.765)], 1.363 [95 % CI (1.029, 1.806)], 1.989 [95 % CI (1.042, 3.799)], and 0.461 [95 % CI (0.315, 0.676)], respectively. In a further ethnicity-based subgroup analysis, HLA-DRB1*08, HLA-DRB1*11, and HLA-DRB1*16 were found to be linked with NPC in Asian, Tunisian, and Caucasian, respectively. In Asian, HLA-DRB1*03, 08, and 10 may elevate the risk whereas HLA-DRB1*09 could lower it. In Tunisian, HLA-DRB1*01 and 11 are the protective factors while HLA-DRB1*03 is the only risk factor. In Caucasian, HLA-DRB1*01 and 03 increase the risk and HLA-DRB1*16 lowers it. The most frequent statistically associated gene is found to be HLA-DRB1*03 which has protective influence on Asian and Tunisian. In conclusion, HLA-DRB1*01, DRB1*03, DRB1*09, and DRB1*10 are related with NPC susceptibility, and the association of HLA-DRB1*08, DRB1*11, and DRB1*16 with NPC risk are significantly different in different ethnicities.

Abstract
In this study, we typed 930 cases of nasopharyngeal carcinoma (NPC) and 1134 normal controls recruited from Hunan province, southern China for human leukocyte antigen-A (HLA-A) locus by sequencing exons 2-4. Very significant associations between HLA-A*02:07, HLA-A*11:01 and NPC were established [25.7% vs 16.18%; odds ratio, OR (95% confidence interval, CI) = 1.79 (1.54-2.09), P < 0.0001 and 21.1% vs 30.42%, OR (95% CI) = 0.61 (0.53-0.70), P<0.0001, respectively]. Further analysis of the molecular basis underlying these associations suggests that cysteine (C) at codon 99 of α2-helix of HLA-A protein is probably deleterious and confers risk to NPC. Convincing evidence was uncovered for negative association of a rare allele in southern Chinese populations, HLA-A*31:01, with NPC [0.22% vs 2.12%, OR (95% CI) = 0.1 (0.04-0.28), P < 0.0001]. rs1059449-A, which encodes arginine (R) at codon 56 of α1-helix of HLA-A protein, was postulated to be crucial for such a pattern of negative association with NPC. A subset of NPC cases (N = 632) and normal controls (N=712) were tested for anti-virus capsid antigen (anti-VCA) immunoglobulin A (IgA), very significant difference in seropositivity for anti-VCA IgA was observed between the two groups [67.56% vs 6.46%, OR (95% CI) = 30.16 (21.42-42.46), P < 0.0001]. However, seropositivity for anti-VCA IgA did not correlate with HLA-A allelic typing in both groups.

Abstract
BACKGROUND Epstein-Barr virus (EBV) is considered to be closely associated with nasopharyngeal carcinoma (NPC), in which EBV-encoded latent membrane protein 1 (LMP1) was found to have an oncogenic role. However, the results published on the LMP1 polymorphism are inconsistent. In the present study, we performed a meta-analysis to determine the frequency of the associations and a more precise association between NPC and EBV LMP1 gene variants (30-bp deletion (del)/XhoI-loss). METHODS Eligible articles met the inclusion/exclusion criteria and were identified in the following electronic databases: PubMed, ScienceDirect, and SciELO. Consequently, the data of interest were extracted and plotted in a table to calculate the frequency and odds ratio (OR) of the outcomes of interest (30-bp del-LMP1/XhoI-loss) in patients with NPC. Study quality (Newcastle-Ottawa Scale (NOS)), publication bias, and heterogeneity were assessed. RESULTS Thirty-one observational studies were included with a total of 2,846 individuals (NPC, n = 1,855; control, n = 991). The risk of bias in relation to study quality evaluated by NOS was considered low. The pooled estimate of the frequency of 30-bp del-LMP1 and XhoI-loss in patients with NPC was 77% (95% confidence interval (CI): 72 to 82) and 82% (95% CI: 71 to 92), respectively. There was an association between 30-bp del-LMP1 and NPC susceptibility (OR = 2.86, 95% CI: 1.35 to 6.07, P = 0.00). Similarly, there was an association between XhoI-loss and NPC (OR = 8.5, 95% CI: 1.7 to 41, P = 0.00). However, when we analyze the co-existence of the 30-bp del-LMP1 and XhoI-loss in patients with NPC, there was no association (OR = 1.09, 95% CI: 0.06 to 18.79, P = 0.002). CONCLUSIONS Our results suggest an association between the 30-bp del-LMP1 and XhoI-loss with NPC susceptibility. However, our data should be interpreted with caution because the sample size was small, and there was heterogeneity between the studies. Thus, future studies are needed with adjusted estimates to simultaneously evaluate multiple factors involved in the development of NPC. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42014013496 .
