[PMID: 38496859 PMCID: PMC10944201 DOI: 10.1016/j.heliyon.2024.e27304] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2022] [Revised: 02/27/2024] [Accepted: 02/27/2024] [Indexed: 03/19/2024] Open
Abstract
Introduction The exact etiology of multiple sclerosis is unknown but recent studies indicated a link between tumor necrosis factor superfamily member 4 and the disease. Polymorphisms located in the regulatory region of the gene may affect its phenotype. Hence, we aimed to investigate the association of promoter polymorphisms of the gene with multiple sclerosis and also to estimate the frequency of haplotypes in the patients and healthy subjects. Methods Two hundred age- and sex-matched subjects including 100 patients and 100 healthy subjects were investigated in the study. Genotype and allele distributions of rs3850641, rs1234313, and rs10912580 polymorphisms in the promoter region of the gene were investigated by polymerase chain reaction-restriction fragment length polymorphism. In addition, haplotype frequencies estimation and linkage disequilibrium analysis were performed by SNPStats web tool. Results The distribution of AA, AG and GG genotypes of rs3850641 was significantly different between the patient and healthy groups (P = 0.009). In addition, frequencies of A and G alleles of rs3850641 were different between the groups (P < 0.001). Also the distribution of rs3850641 genotypes was different between the women of the both groups (P = 0.007). Our analysis revealed that rs3850641 AG (Odds ratio = 0.393, 95 % confidence interval = 0.170-0.907, P = 0.029) and GG (Odds ratio = 0.373, 95 % confidence interval = 0.168-0.830, P = 0.016) genotypes were associated with decreased risk of the disease. However, rs1234313 genotype and allele distributions were not different between the groups. The distribution of rs10912580polymorphism. AA, AG, and GG genotypes was significantly different between the groups (P = 0.007). rs10912580 AG genotype was associated with low risk of the disease (Odds ratio = 0.252, 95 % confidence interval = 0.102-0.623, P = 0.003). The distribution of haplotypes was statistically different between the patient and healthy groups (P < 0.001). A-G-A was the most frequent haplotype among the patients and the estimated frequency was higher than that of the control group (0.5527 versus 0.3739). Conclusion The distribution of rs3850641 and rs10912580 genotypes was different between the patients and healthy subjects. Moreover, rs3850641 AG and GG genotypes and also rs10912580 AG genotype were associated with low risk of the disease in Iranians. Further studies with large groups are recommended to show whether genotype variation in the patients could alter the response to treatment or not.

First report on genome wide association study in western Indian population reveals host genetic factors for COVID-19 severity and outcome. Genomics 2022; 114:110399. [PMID: 35680011 PMCID: PMC9169419 DOI: 10.1016/j.ygeno.2022.110399] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Revised: 05/18/2022] [Accepted: 06/01/2022] [Indexed: 02/07/2023]
Abstract
Different human races across the globe responded in a different way to the SARS-CoV-2 infection leading to different disease severity. Therefore, it is anticipated that host genetic factors have a straight association with the COVID-19. We identified a total 6, 7, and 6 genomic loci for deceased-recovered, asymptomatic-recovered, and deceased-asymptomatic group comparison, respectively. Unfavourable alleles of the markers nearby the genes which are associated with lung and heart diseases such as Tumor necrosis factor superfamily (TNFSF4&18), showed noteworthy association with the disease severity and outcome for the COVID-19 patients in the western Indian population. The markers found with significant association with disease prognosis or recovery are of value in determining the individual's response to SARS-CoV-2 infection and can be used for the risk prediction in COVID-19. Besides, GWAS study in other populations from India may help to strengthen the outcome of this study.

Abstract
OBJECTIVES Acute myeloid leukemia (AML) is still challenging in predicting the prognosis due to its high heterogeneity. Molecular aberrations and abnormalities play a significant prognostic role in AML patients. Our aim of the study was to investigate the prognostic role of TNFRSF4 gene expression in AML patients and its potential effect on treatment protocols. METHODS Bone marrow mononuclear cells were analyzed for TNFRSF4 expression by real-time quantitative PCR as well as of FLT3/ITD and NPM1 mutations in 80 newly diagnosed AML patients and 80 control subjects. RESULTS TNFRSF4 was significantly overexpressed in the AML patients (p < 0.001). TNFRSF4 expression was associated with unfavorable clinical outcomes including treatment response, relapse free survival, and overall survival. On multivariate testing, TNFRSF4 high expression proved to be an independent prognostic marker for clinical remission and relapse free survival but not overall survival. CONCLUSION TNFRSF4 expression was revealed as an unfavorable prognostic marker and might be a target for immunotherapy in the future.

Abstract
OBJECTIVES To test the hypothesis that genetic predisposition to systemic lupus erythematosus (SLE) increases the risk of cardiometabolic disorders. METHODS Using 41 single nucleotide polymorphisms (SNPs) associated with SLE, we calculated a weighted genetic risk score (wGRS) for SLE. In a large biobank we tested the association between this wGRS and 9 cardiometabolic phenotypes previously associated with SLE: atrial fibrillation, ischemic stroke, coronary artery disease, type 1 and type 2 diabetes, obesity, chronic kidney disease, hypertension, and hypercholesterolemia. Additionally, we performed a phenome-wide association analysis (pheWAS) to discover novel clinical associations with a genetic predisposition to SLE. Findings were replicated in the Electronic Medical Records and Genomics (eMERGE) Network. To further define the association between SLE-related risk alleles and the selected cardiometabolic phenotypes, we performed an inverse variance weighted regression (IVWR) meta-analysis. RESULTS The wGRS for SLE was calculated in 74,759 individuals of European ancestry. Among the pre-selected phenotypes, the wGRS was significantly associated with type 1 diabetes (OR [95%CI] =1.11 [1.06, 1.17], P-value = 1.05x10-5). In the PheWAS, the wGRS was associated with several autoimmune phenotypes, kidney disorders, and skin neoplasm; but only the associations with autoimmune phenotypes were replicated. In the IVWR meta-analysis, SLE-related risk alleles were nominally associated with type 1 diabetes (P = 0.048) but the associations were heterogeneous and did not meet the adjusted significance threshold. CONCLUSION A weighted GRS for SLE was associated with an increased risk of several autoimmune-related phenotypes including type I diabetes but not with cardiometabolic disorders.

Front Physiol 2020; 11:539288. [PMID: 33329013 PMCID: PMC7732687 DOI: 10.3389/fphys.2020.539288] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Accepted: 09/17/2020] [Indexed: 12/19/2022] Open
Abstract
Background: Coronary artery disease (CAD) remains the leading cause of mortality worldwide, and its susceptibility is closely associated with genetic modifications. The association between inflammation and CAD has been investigated in detail. This meta-analysis was conducted based on the PRISMA guidelines to evaluate the association between the tumor necrosis factor superfamily member 4 (TNFSF4) gene polymorphisms (rs3861950 T > C and rs1234313 A > G) and the risk of CAD. Methods: The selected criteria included 11 eligible articles containing 18 studies (nine studies included 7,395 cases and 5,296 controls for rs3861950 and nine studies with 6,951 cases and 4,959 controls for rs1234313). Correlations between the two polymorphisms and CAD were estimated by pooling the odds ratios (ORs) with 95% confidence interval (95% CI) in allelic, dominant, recessive, heterozygous, and homozygous models. Results: The pooled analyses demonstrated that the rs3861950 T > C polymorphism was significantly associated with an increased risk of CAD in the Asian population in the allelic model, dominant model, and homozygous model. Furthermore, subgroup analysis based on disease type showed that TNFSF4 rs3861950 T > C had a robust correlation with increased risk of cerebral infarction (CI) in the allelic model, dominant model, heterozygous model, and homozygous model. However, the rs1234313 A > G polymorphism mostly tended to decrease the risk of CAD in the Asian and Caucasian populations in the allelic and dominant model. This single nucleotide polymorphism (SNP) had a close relation to myocardial infarction (MI) susceptibility in the allelic model, dominant model, and heterozygous model. Conclusion: This meta-analysis identified two novel SNPs in TNFSF4 significantly associated with CAD susceptibility.

Abstract
Background Ischemic stroke is a leading cause of mortality and morbidity worldwide. Stenosis or blockage of an artery from atherosclerosis can cause insufficient cerebral blood supply, which leads to ischemic stroke. It has been reported that the polymorphisms of TNFSF4 (tumor necrosis factor super family member 4) are associated with multiple autoimmune diseases. However, it is still unclear whether TNFSF4 gene polymorphisms are associated with ischemic stroke in the Han Chinese population. Here we analyzed the association between TNFSF4 single nucleotide polymorphisms (SNPs) and cerebral arterial thrombosis in the Han Chinese population. Method We consecutively recruited 481 patients with cerebral arterial thrombosis and 538 healthy controls. Neck ultrasonography and magnetic resonance imaging (MRI) were used to evaluate large artery atherosclerosis (LAA) and small vessel disease (SVD), as well as the thickness and calcification of carotid artery. DNA was purified from the peripheral blood samples. TNFSF4 SNPs, rs1234313 and rs45454293, were genotyped using PCR. Results rs1234313 SNP had a significant correlation with the LAA and SVD subtypes in allelic (G vs A), dominate (GG/GA vs AA) and genotypic (GA vs AA; GG vs AA) models, as well as with the calcification of carotid plaque in dominant (GG/GA vs AA, p = 0.022) and genotypic (GA vs AA, p = 0.01) models. rs45454293 SNP had a significant correlation with the LAA and SVD subtypes in allelic (G vs A) and genotypic models, as well as with the thick carotid plaque in allelic (G vs A, p = 0.01) model. Conclusion TNFSF4 SNPs, rs1234313 and rs45454293, are associated with the risk of specific subtypes of cerebral arterial thrombosis in the Han Chinese population.

Abstract
BACKGROUND This meta-analysis was conducted to analyze the correlations of OX40 ligand (OX40L) variants with atherosclerotic cardio-cerebral vascular diseases (ASCVD). METHODS Systematic literature research was conducted in PubMed, Medline, and Embase. All statistical analyses were conducted with Review Manager. RESULTS Totally eighteen studies were enrolled for analyses. Although no any significant correlations between OX40L variants and ASCVD were detected in overall analyses. Further subgroup analyses by ethnicity revealed that rs1234314 variant was significantly associated with ASCVD in East Asians (dominant model: P = 0.03, odds ratios [OR] = 1.15, 95% confidence interval [CI], 1.01-1.31; allele model: P = 0.04, OR = 1.10, 95%CI, 1.00-1.20). When we stratified eligible studies by type of disease, positive results were observed for rs17568 variant in subjects with acute coronary syndrome (ACS) (allele model: P = 0.04, OR = 0.81, 95%CI, 0.65-0.99), for rs1234314 variant in subjects with coronary artery disease (CAD) (dominant model: P = 0.04, OR = 1.16, 95%CI, 1.00-1.35), for rs3850641 variant in subjects with CAD (recessive model: P = 0.02, OR = 1.42, 95%CI, 1.05-1.90) and myocardial infarction (MI) (recessive model: P = 0.03, OR = 1.49, 95%CI, 1.05-2.11). CONCLUSIONS Our findings suggested that rs17568, rs1234314, and rs3850641 variants might serve as genetic biomarkers of certain types of CAD.

Abstract
Tumor necrosis factor superfamily member 4 (TNFSF4), also known as Ox40 ligand (Ox40l), plays an important role in atherosclerosis development. Several studies reported the association between the rs3850641 polymorphism of the TNFSF4 gene and the risk of myocardial infarction (MI). However, the results are inconsistent. In order to explore the relationship between the rs3850641 polymorphism of the TNFSF4 gene and MI, we conducted a case–control study including 454 cases and 512 controls in a Chinese Han population. Genotyping was performed using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. The present study found that AA genotype (AA vs. GG: odds ratio (OR) & 95% confidence interval (CI), 2.00(1.04,3.86), P=0.039; AA vs. AG+GG: OR & 95% CI, 1.93(1.00,3.70), P=0.049) or A allele carriers (A vs. G: OR & 95% CI, 1.27(1.00,1.60), P=0.047) of the rs3850641 polymorphism of the TNFSF4 gene increased the risk of MI. In conclusion, this case–control study confirms that the rs3850641 polymorphism of the TNFSF4 gene increases the risk of MI.

Abstract
Allergic rhinitis (AR) is a common inflammatory disease of the upper airway. Recent evidence suggests that gene‑gene interactions between tumor necrosis factor receptor superfamily 4 (TNFSF4) and B cell lymphocyte kinase (BLK) may have a synergistic effect on T and B cells in determining immunologic aberration, via the nuclear factor‑κB pathway. The present study was performed to evaluate the potential association between specific single nucleotide polymorphisms (SNPs) in the TNFSF4 and BKL genes with susceptibility to AR in Chinese subjects. A population‑based case‑control study was performed in 600 Chinese AR patients and 700 controls. Blood was drawn for DNA extraction, and 9 SNPs (6 in TNFSF4 and 3 in BKL genes) were selected and genotyped. The TNFSF4 SNPs rs1234314 and rs1234315, and the BLK SNPs rs13277113 and rs1600249 were observed to occur in different frequencies between the AR patients and the controls. The CC (rs1234314, rs1234315) and AA (rs1600249, rs13277113) genotypes provided protective effects against AR, whereas the AG (rs13277113) genotype presented a risk factor for AR. The haplotypes ACC in the rs1234313‑rs1234314‑rs1234315 block and GA in the rs2254546‑rs13277113 block significantly decreased the risk of AR, whereas the GGT and AG haplotypes served protective roles. SNP interaction analysis further indicated that there may be synergistic effects among the selected sets of polymorphisms. The present study suggests a novel association between specific TNFSF4 and BLK gene polymorphisms and AR risk, highlighting their potential utility as genetic biomarkers for AR susceptibility in a Chinese Han population.

Abstract
PU.1 is a hematopoietic lineage-specific transcription factor belonging to the Ets family. We investigated the role of PU.1 in the expression of OX40L in dendritic cells (DCs), because the regulatory mechanism of cell type-specific expression of OX40L, which is mainly restricted to antigen-presenting cells, is largely unknown despite the critical involvement in Th2 and Tfh development. PU.1 knockdown decreased the expression of OX40L in mouse DCs. Chromatin immunoprecipitation (ChIP) assays demonstrated that PU.1 constitutively bound to the proximal region of the OX40L promoter. Reporter assays and electrophoretic mobility shift assays revealed that PU.1 transactivated the OX40L promoter through direct binding to the most-proximal Ets motif. We found that this Ets motif is conserved between mouse and human, and that PU.1 bound to the human OX40L promoter in ChIP assay using human monocyte-derived DCs. ChIP assays based on ChIP-seq datasets revealed that PU.1 binds to several sites distant from the transcription start site on the OX40L gene in addition to the most-proximal site in mouse DCs. In the present study, the structure of the OX40L promoter regulated by PU.1 is determined. It is also suggested that PU.1 is involved in mouse OX40L expression via multiple binding sites on the gene.

Abstract
Despite stringent procedures to secure the best HLA matching between donors and recipients, life-threatening complications continue to occur after hematopoietic stem cell transplantation (HSCT). Studying single nucleotide polymorphism (SNP) in genes encoding costimulatory molecules could help identify patients at risk for post-HSCT complications. In a stepwise approach we selected SNPs in key costimulatory molecules including CD274, CD40, CD154, CD28, and TNFSF4 and systematically analyzed their association with post-HSCT outcomes. Our discovery cohort analysis of 1157 HLA-A, -B, -C, -DRB1, and -DQB1 matched cases found that patients with donors homozygous for the C variant of rs10912564 in TNFSF4 (48%) had better disease-free survival (P = .029) and overall survival (P = .009) with less treatment-related mortality (P = .006). Our data demonstrate the TNFSF4C variant had a higher affinity for the nuclear transcription factor Myb and increased percentage of TNFSF4-positive B cells after stimulation compared with CT or TT genotypes. However, these associations were not validated in a more recent cohort, potentially because of changes in standard of practice or absence of a true association. Given the discovery cohort, functional data, and importance of TNFSF4 in infection clearance, TNFSF4C may associate with outcomes and warrants future studies.

Abstract
Large-scale genome-wide association studies (GWAS) have identified 46 loci that are associated with coronary heart disease (CHD). Additionally, 104 independent candidate variants (false discovery rate of 5 %) have been identified (Schunkert H, Konig IR, Kathiresan S, Reilly MP, Assimes TL, Holm H et al. Nat Genet 43:333-8, 2011; Deloukas P, Kanoni S, Willenborg C, Farrall M, Assimes TL, Thompson JR et al. Nat Genet 45:25-33, 2012; C4D Genetics Consortium. Nat Genet 43:339-44, 2011). The majority of the causal genes in these loci function independently of conventional risk factors. It is postulated that a number of the CHD-associated genes regulate basic processes in the vascular cells involved in atherosclerosis, and that study of the signaling pathways that are modulated in this cell type by causal regulatory variation will provide critical new insights for targeting the initiation and progression of disease. In this review, we will discuss the types of experimental approaches and data that are critical to understanding the molecular processes that underlie the disease risk at 9p21.3, TCF21, SORT1, and other CHD-associated loci.

Abstract
OBJECTIVE To clarify the association between atherosclerotic cerebral infarction (ACI) and the single nucleotide polymorphisms (SNP) rs1234313 and rs1234314 (in TNFSF4) and rs17568 (in TNFRSF4). METHODS Genomic DNA was extracted from peripheral blood of patients with ACI and healthy control subjects. The presence of carotid plaque was determined. Rs1234313, rs1234314 and rs17568 were characterized via SNP genotyping assay and verified by DNA sequencing. RESULTS Genotype distributions were in Hardy-Weinberg equilibrium. There were no significant differences in the allele and genotype distributions of rs1234313, rs1234314 and rs17568 between patients with ACI (n = 450) and healthy control subjects (n = 378), or between patients with ACI and carotid plaque (n = 342) and controls. CONCLUSIONS There were no significant associations between rs1234313, rs1234314 and rs17568 and ACI risk in a Han Chinese population.

Trans-ancestral studies fine map the SLE-susceptibility locus TNFSF4. PLoS Genet 2013; 9:e1003554.

Abstract
We previously established an 80 kb haplotype upstream of TNFSF4 as a susceptibility locus in the autoimmune disease SLE. SLE-associated alleles at this locus are associated with inflammatory disorders, including atherosclerosis and ischaemic stroke. In Europeans, the TNFSF4 causal variants have remained elusive due to strong linkage disequilibrium exhibited by alleles spanning the region. Using a trans-ancestral approach to fine-map the locus, utilising 17,900 SLE and control subjects including Amerindian/Hispanics (1348 cases, 717 controls), African-Americans (AA) (1529, 2048) and better powered cohorts of Europeans and East Asians, we find strong association of risk alleles in all ethnicities; the AA association replicates in African-American Gullah (152,122). The best evidence of association comes from two adjacent markers: rs2205960-T (P=1.71 × 10(-34) , OR=1.43[1.26-1.60]) and rs1234317-T (P=1.16 × 10(-28) , OR=1.38[1.24-1.54]). Inference of fine-scale recombination rates for all populations tested finds the 80 kb risk and non-risk haplotypes in all except African-Americans. In this population the decay of recombination equates to an 11 kb risk haplotype, anchored in the 5' region proximal to TNFSF4 and tagged by rs2205960-T after 1000 Genomes phase 1 (v3) imputation. Conditional regression analyses delineate the 5' risk signal to rs2205960-T and the independent non-risk signal to rs1234314-C. Our case-only and SLE-control cohorts demonstrate robust association of rs2205960-T with autoantibody production. The rs2205960-T is predicted to form part of a decameric motif which binds NF-κBp65 with increased affinity compared to rs2205960-G. ChIP-seq data also indicate NF-κB interaction with the DNA sequence at this position in LCL cells. Our research suggests association of rs2205960-T with SLE across multiple groups and an independent non-risk signal at rs1234314-C. rs2205960-T is associated with autoantibody production and lymphopenia. Our data confirm a global signal at TNFSF4 and a role for the expressed product at multiple stages of lymphocyte dysregulation during SLE pathogenesis. We confirm the validity of trans-ancestral mapping in a complex trait.

Abstract
The Mef2 family transcriptional regulator Mef2c (myocyte enhancer factor 2c) is highly expressed in maturing bone marrow and peripheral mature B-cells. To evaluate the role of this transcription factor in B-cell development, we generated a B-cell-specific conditional deletion of Mef2c using the Mb-1-Cre transgene that is expressed during the early stages of immunoglobulin rearrangement. Young mice possessing this defect demonstrated a significant impairment in B-cell numbers in bone marrow and spleen. This phenotype was evident in all B-cell subsets; however, as the animals mature, the deficit in the peripheral mature B-cell compartments was overcome. The absence of Mef2c in mature B-cells led to unique CD23+ and CD23- subsets that were evident in Mef2c knockout primary samples as well as Mef2c-deficient cultured, differentiated B-cells. Genome-wide expression analysis of immature and mature B-cells lacking Mef2c indicated altered expression for a number of key regulatory proteins for B-cell function including Ciita, CD23, Cr1/Cr2 and Tnfsf4. Chromatin immunoprecipitation analysis confirmed Mef2c binding to the promoters of these genes indicating a direct link between the presence (or absence) of Mef2c and altered transcriptional control in mature B-cells.

Association of OX40L polymorphisms with sporadic breast cancer in northeast Chinese Han population. PLoS One 2012; 7:e41277.

Abstract
OX40L is an important costimulatory molecule that plays a crucial role in the regulation of T-cell-mediated immunity. The interaction of OX40-OX40L is involved in the pathogenesis of multiple autoimmune and inflammatory diseases such as systemic lupus erythematosus (SLE), carotid artery disease and cancer. The genetic variants of OX40L can increase the risk of SLE, atherosclerosis, systemic sclerosis and show gender-specific effects in some studies. Accordingly, we performed a case-control study including 557 breast cancer patients and 580 age- and sex-matched healthy controls to investigate whether single nucleotide polymorphisms (SNPs) in the OX40L gene are associated with sporadic breast cancer susceptibility and progression in Chinese Han women. Seven SNPs of OX40L (rs6661173, rs1234313, rs3850641, rs1234315, rs12039904, rs844648 and rs10912580) were genotyped with the method of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The results indicated that rs3850641G allele could increase the susceptibility to breast cancer (P = 0.009662), even in the validation study (P = 0.0001515). A significant association between rs3850641 and breast cancer risk was observed under the additive model and dominant model (P = 0.01042 and 0.01942, respectively). The haplotype analysis showed that haplotype A(rs844648)A(rs10912580) was significantly associated with breast cancer, even after 10,000 permutations for haplotypes in block only (P = 0.0003). In clinicopathologic features analysis, the association between rs1234315 and C-erbB2 status was significant (P = 0.02541). Our data primarily indicates that rs3850641 of OX40L gene contributes to sporadic breast carcinogenesis in a northeast Chinese Han population.

Abstract
Differences between animal and human atherosclerosis have led to the requirement for clinical data, imaging information and biological material from large numbers of patients and healthy persons. Where such "biobanks" exist, they have been fruitful sources for genomewide association, diagnostic accuracy, ethnicity, and risk stratification cohort studies. In addition once established, they attract funding for future projects. Biobanks require a network of medical contributors, secure storage facilities, bioinformatics expertise, database managers, and ethical working practices to function optimally. There is the opportunity for collaboration between individual biobanks to further amplify the advantages afforded.
