A common NFKB1 variant detected through antibody analysis in UK Biobank predicts risk of infection and allergy. Am J Hum Genet 2024; 111:295-308. [PMID: 38232728 PMCID: PMC10870136 DOI: 10.1016/j.ajhg.2023.12.013] [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: 01/06/2023] [Revised: 12/07/2023] [Accepted: 12/10/2023] [Indexed: 01/19/2024] Open
Abstract
Infectious agents contribute significantly to the global burden of diseases through both acute infection and their chronic sequelae. We leveraged the UK Biobank to identify genetic loci that influence humoral immune response to multiple infections. From 45 genome-wide association studies in 9,611 participants from UK Biobank, we identified NFKB1 as a locus associated with quantitative antibody responses to multiple pathogens, including those from the herpes, retro-, and polyoma-virus families. An insertion-deletion variant thought to affect NFKB1 expression (rs28362491), was mapped as the likely causal variant and could play a key role in regulation of the immune response. Using 121 infection- and inflammation-related traits in 487,297 UK Biobank participants, we show that the deletion allele was associated with an increased risk of infection from diverse pathogens but had a protective effect against allergic disease. We propose that altered expression of NFKB1, as a result of the deletion, modulates hematopoietic pathways and likely impacts cell survival, antibody production, and inflammation. Taken together, we show that disruptions to the tightly regulated immune processes may tip the balance between exacerbated immune responses and allergy, or increased risk of infection and impaired resolution of inflammation.

Abstract
Inflammatory bowel disease (IBD) is an idiopathic, chronic condition characterized by episodes of inflammation in the gastrointestinal tract. The nuclear factor κB (NF-κB) system describes a family of dimeric transcription factors. Canonical NF-κB signaling is stimulated by and enhances inflammation, whereas noncanonical NF-κB signaling contributes to immune organogenesis. Dysregulation of NF-κB factors drives various inflammatory pathologies, including IBD. Signals from many immune sensors activate NF-κB subunits in the intestine, which maintain an equilibrium between local microbiota and host responses. Genetic association studies of patients with IBD and preclinical mouse models confirm the importance of the NF-κB system in host defense in the gut. Other studies have investigated the roles of these factors in intestinal barrier function and in inflammatory gut pathologies associated with IBD. NF-κB signaling modulates innate and adaptive immune responses and the production of immunoregulatory proteins, anti-inflammatory cytokines, antimicrobial peptides, and other tolerogenic factors in the intestine. Furthermore, genetic studies have revealed critical cell type-specific roles for NF-κB proteins in intestinal immune homeostasis, inflammation, and restitution that contribute to the etiopathology of IBD-associated manifestations. Here, we summarize our knowledge of the roles of these NF-κB pathways, which are activated in different intestinal cell types by specific ligands, and their cross-talk, in fueling aberrant intestinal inflammation. We argue that an in-depth understanding of aberrant immune signaling mechanisms may hold the key to identifying predictive or prognostic biomarkers and developing better therapeutics against inflammatory gut pathologies.

[PMID: 36791052 PMCID: PMC9931161 DOI: 10.1371/journal.pone.0280839] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Accepted: 01/10/2023] [Indexed: 02/16/2023] Open
Abstract
Graph analytical approaches permit identifying novel genes involved in complex diseases, but are limited by (i) inferring structural network similarity of connected gene nodes, ignoring potentially relevant unconnected nodes; (ii) using homogeneous graphs, missing gene-disease associations' complexity; (iii) relying on disease/gene-phenotype associations' similarities, involving highly incomplete data; (iv) using binary classification, with gene-disease edges as positive training samples, and non-associated gene and disease nodes as negative samples that may include currently unknown disease genes; or (v) reporting predicted novel associations without systematically evaluating their accuracy. Addressing these limitations, we develop the Heterogeneous Integrated Graph for Predicting Disease Genes (HetIG-PreDiG) model that includes gene-gene, gene-disease, and gene-tissue associations. We predict novel disease genes using low-dimensional representation of nodes accounting for network structure, and extending beyond network structure using the developed Gene-Disease Prioritization Score (GDPS) reflecting the degree of gene-disease association via gene co-expression data. For negative training samples, we select non-associated gene and disease nodes with lower GDPS that are less likely to be affiliated. We evaluate the developed model's success in predicting novel disease genes by analyzing the prediction probabilities of gene-disease associations. HetIG-PreDiG successfully predicts (Micro-F1 = 0.95) gene-disease associations, outperforming baseline models, and is validated using published literature, thus advancing our understanding of complex genetic diseases.

NFKB1 Gene Mutant Was Associated with Prognosis of Coronary Artery Disease and Exacerbated Endothelial Mitochondrial Fission and Dysfunction. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:9494926. [PMID: 36317060 PMCID: PMC9617727 DOI: 10.1155/2022/9494926] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/22/2022] [Revised: 08/11/2022] [Accepted: 09/21/2022] [Indexed: 11/18/2022]
Abstract
Endothelial apoptosis is the core pathological change in atherosclerotic cardiovascular disease, including coronary artery disease (CAD). Determining the molecular mechanisms underlying endothelial apoptosis is important. Nuclear factor kappa B (NF-κB) is a crucial transcription factor for controlling apoptosis. Our previous study demonstrated that the -94 ATTG ins/del mutant in the promoter of NFKB1 gene (rs28362491) is a risk factor for CAD. In the present study, we found that NFKB1 rs28362491 polymorphism was positively associated with increased major adverse cardiac and cerebrovascular events (MACCEs) in CAD patients. After adjusting for confounding factors including age, smoking, hypertension, glucose, and low-density lipoprotein cholesterol, the mutant DD genotype was an independent predictor of MACCEs (OR = 2.578, 95%CI = 1.64–4.05, P = 0.003). The in vitro study showed that mutant human umbilical vein endothelial cells (DD-mutant HUVECs) were more susceptible to high-glucose/palmitate-induced apoptosis, which was accompanied by decreased p50 expression and increased expression of cleaved caspase-3, Cytochrome c, and phospho-p65 (P < 0.05). The mitochondrial membrane potential was significantly lower, while increasing levels of mtROS and more opening of the mPTP were observed in DD-mutant HUVECs (P < 0.05). Furthermore, the percentage of cells with fragmented or spherical mitochondria was significantly higher in DD-mutant HUVECs than in wild-type cells (genotype II HUVECs) (P < 0.05). In addition, after stimulation with high glucose/palmitate, the NFKB1 gene mutant significantly increased the expression of Drp1, which indicated that the NFKB1 gene mutant affected the expression of mitochondrial morphology-related proteins, leading to excessive mitochondrial fission. In conclusion, the mutant DD genotype of the NFKB1 gene was an independent predictor of worse long-term prognosis for CAD patients. DD-mutant HUVECs exhibited abnormal activation of the NF-κB pathway and increased Drp1 expression, which caused excessive mitochondrial fission and dysfunction, ultimately leading to increased apoptosis.

Abstract
Large scale genetic association studies have identified many trait-associated variants and understanding the role of these variants in the downstream regulation of gene-expressions can uncover important mediating biological mechanisms. Here we propose ARCHIE, a summary statistic based sparse canonical correlation analysis method to identify sets of gene-expressions trans-regulated by sets of known trait-related genetic variants. Simulation studies show that compared to standard methods, ARCHIE is better suited to identify "core"-like genes through which effects of many other genes may be mediated and can capture disease-specific patterns of genetic associations. By applying ARCHIE to publicly available summary statistics from the eQTLGen consortium, we identify gene sets which have significant evidence of trans-association with groups of known genetic variants across 29 complex traits. Around half (50.7%) of the selected genes do not have any strong trans-associations and are not detected by standard methods. We provide further evidence for causal basis of the target genes through a series of follow-up analyses. These results show ARCHIE is a powerful tool for identifying sets of genes whose trans-regulation may be related to specific complex traits.

Abstract
OBJECTIVE This study was performed to replicate the associations of genetic polymorphisms within nuclear factor-κB (NF-κB) signaling pathway genes with rheumatoid arthritis (RA), and to further examine genetic interactions in a Chinese population. METHODS A total of eleven single-nucleotide polymorphisms (SNPs) were genotyped in 594 RA patients and 604 healthy controls. RESULTS Genetic association analysis revealed that NFKBIE rs2233434, TNIP1 rs10036748 and BLK rs13277113 were significantly associated with RA, cyclic citrullinated peptide (CCP)-positive RA and rheumatoid factor (RF)-positive RA, and TNFAIP3 rs2230926 was significantly associated with CCP-positive RA. Significant additive interaction was observed between NFKB1 rs28362491 and IKBKE rs12142086 (RERI = 0.76, 95% CI 0.13-1.38; AP = 0.57, 95% CI 0.11-1.03), NFKBIE rs2233434 and BLK rs13277113 (RERI = 1.41, 95% CI 0.88-1.94; AP = 0.85, 95% CI 0.50-1.20), NFKBIL rs2071592 and TNIP1 rs10036748 (RERI = 0.59, 95% CI 0.17-1.02; AP = 0.46, 95% CI 0.05-0.87), UBE2L3 rs5754217 and TNFSF4 rs2205960 (RERI = 0.50, 95% CI 0.16-0.84; AP = 0.57, 95% CI 0.09-1.05). Significant multiplicative interaction was detected between BLK rs13277113 and UBE2L3 rs5754217 (p = 0.02), BLK rs13277113 and TNFSF4 rs2205960 (p = 0.03). CONCLUSIONS Our results lent further support to the role of NF-κB signaling pathway in the pathogenesis of RA from a genetic perspective.

Abstract
Myocardial infarction (MI), the leading cause of mortality and disability worldwide, is a disease in which multiple environmental and genetic factors are involved. Recently, researches suggested that insertion/deletion (ins/del) variation of NFKB1 gene rs28362491 is a functional polymorphism. In the present study, we aimed to explore the relation between variation of NFKB1 gene rs28362491 and MI by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 359 MI patients and 1085 control participants. Gensini score was used to evaluate the degree of coronary artery stenosis in MI patients. The plasma levels of interleukin-6 (IL-6), IL-8, malonaldehyde (MDA) and superoxide dismutase (SOD) were randomly measured by ELISA both in MI patients and control participants. We found that the detected frequencies of D allele (41.2% vs. 36.4%, P = 0.021) and DD genotype (17.5% vs. 12.0%, P = 0.022) were significantly higher in MI patients than in control participants. Compared with II or ID genotype carriers, the Gensini score in MI patients with DD genotype was 32-43% higher (both P < 0.001). Moreover, DD genotype carries had more diseased coronary arteries (P = 0.001 vs. II or ID genotype). Of note, IL-6 levels in MI patients carrying DD genotype were significantly higher than that in control participants and other genotype carriers in MI patients (both P < 0.05). In conclusion, NFKB1 gene rs28362491 DD genotype was associated with a higher risk of MI and more severe coronary artery lesion, which also had a potential influence on the level of inflammatory cytokine IL-6.

Abstract
Acute graft-versus-host disease (aGVHD) is a severe inflammatory complication of haematopoeitic stem cell transplantation. The nuclear factor- Kappa Beta (NF-κB) signaling pathway regulates T cell activation. The NF-κB controls the expression of microRNA-146a (miR-146a) that in turn regulates NF-κB activation through a negative feedback loop. We aim to analyze the association between NF-κB1 encoding p50 (rs28362491, -94 in.ertion/deletion ATTG) and miR-146a (rs2910164, G > C) polymorphisms and risk of aGVHD. Genotyping was performed for 135 HLA-matched donors using polymerase chain reaction- restriction fragment length polymorphism (PCR-RFLP).The incidence of aGVHD grades II-IV was 24/135 (17.8 %). NF-κB1 genotype and cytomegalovirus infection were significantly associated with risk of aGVHD II-IV (p = 0.022, HR = 3.17, 95 % CI:1.18-8.51 and p = 0.048, HR = 2.56, 95 % CI:1.01-6.52, respectively). In multivariate analysis, NF-κB1homozygous deletion/deletion genotype was the only independent risk factor associated with aGVHD II-IV (p = 0.013, HR = 3.50, 95 % CI:1.30-9.44). No significant association could be observed between miR-146a polymorphism and aGVHD. Combined NF-κB1 and miR146a genotype analysis warrants investigation in a larger cohort. Our preliminary data do not support the association between miR146a and aGVHD, but suggest an association between NF-κB1 and risk of aGVHD that may pave the way for the development of a novel targeted therapy if proved in a larger cohort.

Abstract
Human gammaherpesvirus 8 (HHV-8) is the etiologic agent of Kaposi's sarcoma, multicentric Castleman's disease and primary effusion lymphoma. Like other herpesviruses, the HHV-8 may exhibit latent or lytic cycle, both regulated by viral and host factors. Regarding host factors, we analysed the association of polymorphisms in NFkB1 promoter (NFkB1-94 ins/del ATTG) and NFκBIA gene (NFκBIA 3'UTR A→G) with the development of antibodies against latent or lytic antigens from HHV-8. The ins/del [OR 7.9 (95% CI 3.3-19.1), p < 0.001], AG [OR 12.3 (95% CI 4.3-34.9) p < 0.001], GG [OR 9.4 (95% CI 3.2-27.9), p < 0.001], ins/del + AG [OR 94.5 (95% CI 9.6-924.4), <0.0001], ins/del + GG [OR 50.4 (95% CI 5.2-482.2, p < 0.0001] and G allele [OR 3.3 (95% CI 2.0-5.6), p < 0.001] were strongly related with the presence of antibodies to lytic antigens. This is the first association of polymorphisms in NFκB1 promoter and NFκBIA gene with the development of antibodies against HHV-8.

Abstract
The acute coronary syndrome (ACS) is a complex disease where genetic and environmental factors are involved. NF-κB, a central regulator of inflammation, is involved in various inflammatory diseases. The aim of the present study was to explore the association between NFKB1 gene rs28362491 (-94ATTGins/del) polymorphism and ACS. A total of 778 ACS patients and 1112 healthy subjects were included in our study. The TaqMan SNP genotyping assays was used to analyze the rs28362491 polymorphism. The lesion extent of coronary artery was assessed by Gensini Score and lesion vessel number in ACS patients. For total and males, the frequencies of the mutant DD genotype and D allele were significantly higher in ACS patients than that in control subjects (total: DD genotype: 18.0 vs 14.1%, P=0.009, D allele: 43.0 vs 37.9%, P=0.002, males: DD genotype: 20.6 vs 15.3%, P=0.042, D allele: 44.2 vs 38.8%, P=0.013). After multivariate logistic regression analysis, we found that individuals with mutant DD genotype had 1.329-fold higher risk of ACS compared with individuals with ID and II genotypes. Moreover, ACS patients with DD genotype were worse stenosis of coronary artery compared with patients carrying II or ID genotype. In conclusion, our study demonstrated that the mutant DD genotype of NFKB1 gene was associated with the risk and severity of ACS in Han population in Xinjiang, northwest of China.

Abstract
The progression of ischemic stroke is associated with inflammatory response, in which the nuclear factor kappa B subunit 1 (NFKB1) plays an important role. The aim of present study was to determine whether promoter single nucleotide polymorphism (SNP) in the NFKB1 gene was contributed to susceptibility of ischemic stroke. One hundred twenty-one Korean adult patients with ischemic stroke (65.7±12.1 years in age) and 291 Korean healthy controls (63.0±9.3 years in age) were recruited. We genotyped a promoter SNP (rs11940017, −1727, C/T) of NFKB1 gene using direct sequencing in 121 Korean ischemic stroke patients and 291 control subjects. The T/C genotype of rs11940017 SNP in the codominant model (vs. the T/T genotype) (odds ratio [OR], 0.38; 95% confidence interval [CI], 0.15–0.92; P=0.032) and the genotype containing C allele (T/C and C/C) in the dominant model (vs. the T/T genotype) (OR, 0.33; 95% CI, 0.14–0.81; P=0.0068) were associated with a decreased risk of ischemic stroke. The frequency of C allele was decreased in ischemic stroke patients, compared with control subjects (OR, 0.31; 95% CI, 0.13–0.74; P=0.008). These results suggest that the promoter SNP (rs11940017, −1727, C/T) of NFKB1 gene may affect ischemic stroke susceptibility in Korean population.

Abstract
Coronary artery disease (CAD) is considered as a chronic inflammatory disease initiated from early childhood. Nuclear factor κB (NF κB) and κB1A (NF κB1A) are the key regulators of inflammatory responses. The NFKB1 -94ATTG ins/del and NFKB1A -826C/T polymorphisms may contribute to the development of CAD. The aim of the present study was to investigate the association of these polymorphisms with the risk of CAD. The study population included 120 patients with angiographically confirmed CAD and 100 matched controls. Genotyping of NFKB1 -94ATTG ins/del and NFKB1A -826C/T polymorphism was performed using PCR-RFLP method. Lipid level was determined by routine colorimetric methods. Statistical analysis was done by SPSS 16 software. Results indicated that the genotypic (P=0.041) and allelic (P=0.009) distribution of the NFKB1-94ATTG ins/del polymorphism was significantly different between the two groups. In the univariate analysis (ins/ins genotype as reference), the del/del genotype (OR=2.88, 95% CI=1.21-6.84, P=0.015) but not ins/del genotype (OR=1.48, 95% CI=0.83-2.64, P=0.191) was significantly associated with the increased risk of CAD. In the multiple binary logistic regression analysis, diabetes, hypertension, smoking, LDL-cholesterol, total cholesterol, HDL-cholesterol and NFKB1 -94ATTG del/del genotype were identified as significant and independent risk factors for CAD development. The distribution of genotypes and alleles of NFKB1A -826C/T polymorphism was not significantly different between the two groups. In conclusion the present study identified NFKB1 -94ATTG ins/del polymorphism but not NFKB1A -826C/T polymorphism as a significant and independent risk factor for development and severity of CAD.

Meat and fiber intake and interaction with pattern recognition receptors (TLR1, TLR2, TLR4, and TLR10) in relation to colorectal cancer in a Danish prospective, case-cohort study. Am J Clin Nutr 2018; 107:465-479. [PMID: 29566186 DOI: 10.1093/ajcn/nqx011] [Citation(s) in RCA: 26] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2017] [Accepted: 10/20/2017] [Indexed: 12/13/2022] Open
Abstract
Background Meat and dietary fiber are associated with increased and decreased risk of colorectal cancer (CRC), respectively. Toll-like receptors (TLRs) regulate the intestinal immune response in a complex interplay between the mucosal epithelium and the microbiota and may therefore be important modulators of diet-induced CRC together with other inflammatory mediators. Objective Our aim was to investigate the association between functional TLR polymorphisms and risk of CRC and the interaction with dietary factors. Additionally, interactions with previously studied polymorphisms in IL10, IL1B, PTGS2, and NFKB1 were assessed in order to examine possible biological pathways in meat-induced CRC. Design A nested case-cohort study of 897 CRC cases and 1689 randomly selected participants from the Danish prospective "Diet, Cancer and Health" study encompassing 57,053 persons was performed using Cox proportional hazard models and the likelihood ratio test. Results We found associations between polymorphisms in TLR2 (P = 0.018) and TLR4 (P = 0.044) and risk of CRC per se, interactions between intake of red and processed meat (10 g/d) and polymorphisms in TLR1 (P-interaction = 0.032) and TLR10 (P-interaction = 0.026 and 0.036), and intake of cereals (50 g/d) and TLR4 (P-interaction = 0.044) in relation to risk of CRC. Intake of red and processed meat also interacted with combinations of polymorphisms in TLR1 and TLR10 and polymorphisms in NFKB1, IL10, IL1B, and PTGS2 (P-interaction; TLR1/rs4833095 × PTGS2/rs20417 = 0.021, TLR10/rs11096955 × IL10/rs3024505 = 0.047, TLR10/rs11096955 × PTGS2/rs20417 = 0.017, TLR10/rs4129009 × NFKB1/rs28362491 = 0.027, TLR10/rs4129009 × IL1B/rs4848306 = 0.020, TLR10/rs4129009 × IL1B/rs1143623 = 0.021, TLR10/rs4129009 × PTGS2/rs20417 = 0.027), whereas intake of dietary fiber (10 g/d) interacted with combinations of polymorphisms in TLR4, IL10, and PTGS2 (P-interaction; TLR4/rs1554973 × IL10/rs3024505 = 0.0012, TLR4/rs1554973 × PTGS2/rs20417 = 0.0041, TLR4/rs1554973 × PTGS2/rs5275 = 0.0064). Conclusions Our study suggests that meat intake may activate TLRs at the epithelial surface, leading to CRC via inflammation by nuclear transcription factor-κB-initiated transcription of inflammatory genes, whereas intake of fiber may protect against CRC via TLR4-mediated secretion of interleukin-10 and cyclooxygenase-2. Our results should be replicated in other prospective cohorts with well-characterized participants. The trial was registered at www.clinicaltrials.gov as NCT03250637.

Abstract
Background: The humoral system is activated and various cytokines are released due to infections in tissues and traumatic damage. Nuclear factor-kappa B dimers are encoded by nuclear factor-kappa B genes and regulate transcription of several crucial proteins of inflammation such as tumour necrosis factor-alpha. Aims: To investigate the possible effect of polymorphisms on tumour necrosis factor-alpha serum levels with clinical and prognostic parameters of sepsis by determining the nuclear factor-kappa B-1-94 ins/del ATTG and tumour necrosis factor-alpha (-308 G/A) gene polymorphisms and tumour necrosis factor-alpha serum levels. Study Design: Case-control study. Methods: Seventy-two patients with sepsis and 104 healthy controls were included in the study. In order to determine the polymorphisms of nuclear factor-kappa B-1-94 ins/del ATTG and tumour necrosis factor-alpha (-308 G/A), polymerase chain reaction–restriction fragment length polymorphism analysis was performed and serum tumour necrosis factor-alpha levels were determined using an enzyme-linked immunosorbent assay. Results: We observed no significant differences in tumour necrosis factor-alpha serum levels between the study groups. In the patient group, an increase in the tumour necrosis factor-alpha serum levels in patients carrying the tumour necrosis factor-alpha (-308 G/A) A allele compared to those without the A allele was found to be statistically significant. Additionally, an increase in the tumour necrosis factor-alpha serum levels in patients carrying tumour necrosis factor-alpha (-308 G/A) AA genotype compared with patients carrying the AG or GG genotypes was statistically significant. No significant differences were found in these 2 polymorphisms between the patient and control groups (p>0.05). Conclusion: Our results showed the AA genotype and the A allele of the tumour necrosis factor-alpha (-308 G/A) polymorphism may be used as a predictor of elevated tumour necrosis factor-alpha levels in patients with sepsis.

Inhibition of corticotropin-releasing hormone receptor 1 and activation of receptor 2 protect against colonic injury and promote epithelium repair. Sci Rep 2017; 7:46616.

Abstract
Maternal separation (MS) in neonates can lead to intestinal injury. MS in neonatal mice disrupts mucosal morphology, induces colonic inflammation and increases trans-cellular permeability. Several studies indicate that intestinal epithelial stem cells are capable of initiating gut repair in a variety of injury models but have not been reported in MS. The pathophysiology of MS-induced gut injury and subsequent repair remains unclear, but communication between the brain and gut contribute to MS-induced colonic injury. Corticotropin-releasing hormone (CRH) is one of the mediators involved in the brain–gut axis response to MS-induced damage. We investigated the roles of the CRH receptors, CRHR1 and CRHR2, in MS-induced intestinal injury and subsequent repair. To distinguish their specific roles in mucosal injury, we selectively blocked CRHR1 and CRHR2 with pharmacological antagonists. Our results show that in response to MS, CRHR1 mediates gut injury by promoting intestinal inflammation, increasing gut permeability, altering intestinal morphology, and modulating the intestinal microbiota. In contrast, CRHR2 activates intestinal stem cells and is important for gut repair. Thus, selectively blocking CRHR1 and promoting CRHR2 activity could prevent the development of intestinal injuries and enhance repair in the neonatal period when there is increased risk of intestinal injury such as necrotizing enterocolitis.

Abstract
The present study attempted to identify potential key genes and pathways of peri-implantitis, and to investigate the possible mechanisms associated with it. An array data of GSE57631 was downloaded, including six samples of peri-implantitis tissue and two samples of normal tissue from the Gene Expression Omnibus (GEO) database. The differentially expressed genes (DEGs) in the peri-implantitis samples compared with normal ones were analyzed with the limma package. Moreover, Gene Ontology annotation and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses for DEGs were performed by DAVID. A protein-protein interaction (PPI) network was established using Cytoscape software, and significant modules were analyzed using Molecular Complex Detection. A total of 819 DEGs (759 upregulated and 60 downregulated) were identified in the peri-implantitis samples compared with normal ones. Moreover, the PPI network was constructed with 413 nodes and 1,114 protein pairs. Heat shock protein HSP90AA1 (90 kDa α, member 1), a hub node with higher node degrees in module 4, was significantly enriched in antigen processing, in the presentation pathway and nucleotide-binding oligomerization domain (NOD)-like receptor-signaling pathway. In addition, nuclear factor-κ-B1 (NFKB1) was enriched in the NOD-like receptor-signaling pathway in KEGG pathway enrichment analysis for upregulated genes. The proteasome is the most significant pathway in module 1 with the highest P-value. Therefore, the results of the present study suggested that HSP90AA1 and NFKB1 may be potential key genes, and the NOD-like receptor signaling pathway and proteasome may be potential pathways associated with peri-implantitis development.

Abstract
Nuclear factor κappa B (NF-κB) is an important transcription factor in the development and progression of coronary artery disease (CAD). Recent evidence suggests that -94 ATTG ins/del mutant in the promoter of NFKB1 gene is an essential functional mutant. The present study demonstrated the frequencies of the del/del (DD) genotype and del (D) allele were significantly higher in CAD patients than in controls. CAD patients carrying mutant DD genotype had worse stenosis of diseased coronary arteries compared to those carrying ins/ins (II) or ins/del (ID) genotype. Plasma levels of endothelial nitric oxide synthase (eNOS) were lower, while inflammatory cytokine incnterlukin-6 (IL-6) was higher in CAD patients with DD genotype than those with II or ID genotype (both P<0.05). In vitro study showed that mutant human umbilical vein endothelial cells (DD genotype HUVECs) were more susceptible to H2O2-induced apoptosis, which was accompanied with a decreased Bcl-2 expression. Further, mutant HUVECs had lower eNOS but higher IL-6 mRNA levels and decreased phosphorylation of eNOS under H2O2-stimulation (both P<0.05). Compared to wild type cells (II genotype), significantly downregulated protein expression of total NF-κB p50 subunit were observed in mutant HUVECs with or without oxidative stress, and a lower expression of unclear p50 was associated with a decreased p50 nuclear translocation in mutant HUVECs versus wild type cells under H2O2-stimulation (both P<0.05). In conclusion, mutant DD genotype of NFKB1 gene is associated with the risk and severity of CAD. Dwonregulation of NF-κB p50 subunit leads to exacerbated endothelial dysfunction and apoptosis and enhanced inflammatory response that is the potential underlying mechanism.

Abstract
Common variable immunodeficiency (CVID), characterized by recurrent infections, is the most prevalent symptomatic antibody deficiency. In ∼90% of CVID-affected individuals, no genetic cause of the disease has been identified. In a Dutch-Australian CVID-affected family, we identified a NFKB1 heterozygous splice-donor-site mutation (c.730+4A>G), causing in-frame skipping of exon 8. NFKB1 encodes the transcription-factor precursor p105, which is processed to p50 (canonical NF-κB pathway). The altered protein bearing an internal deletion (p.Asp191_Lys244delinsGlu; p105ΔEx8) is degraded, but is not processed to p50ΔEx8. Altered NF-κB1 proteins were also undetectable in a German CVID-affected family with a heterozygous in-frame exon 9 skipping mutation (c.835+2T>G) and in a CVID-affected family from New Zealand with a heterozygous frameshift mutation (c.465dupA) in exon 7. Given that residual p105 and p50—translated from the non-mutated alleles—were normal, and altered p50 proteins were absent, we conclude that the CVID phenotype in these families is caused by NF-κB1 p50 haploinsufficiency.

Abstract
OBJECTIVES Coronary artery disease (CAD) is the most common chronic inflammatory disease worldwide. NF-κB, a central regulator of inflammation, is involved in various inflammatory diseases. The aim of this study was to investigate the association between NFKB1 and NFKBIA polymorphisms and the susceptibility to CAD and their impact on plasma levels of IL-6 in a Chinese Uygur population. METHODS We genotyped NFKB1-94ins/del ATTG (rs28362491) and NFKBIA3' UTR A/G (rs696) using TaqMan SNP genotyping assays in 960 Uygur CAD cases and Uygur 1060 CAD-negative controls. IL-6 plasma levels were measured in 360 stable angina pectoris (SAP) cases and 360 controls using ELISA method. RESULTS There was no significant difference in the distribution of the genotypes and alleles of rs696 polymorphism in CAD cases and controls. Significant difference in the frequency of genotypes (P = 0.001) and alleles (P = 0.001) of rs28362491 polymorphism was observed in CAD cases compared to controls. In multivariate logistic regression analysis, SNP rs28362491 was consistently associated with CAD risk in a recessive model after adjustment for cardiovascular risk factors (OR = 1.581, 95% CI 1.222 to 2.046, P<0.001). SAP cases had significantly higher plasma levels of IL-6 compared to controls (P<0.001). General linear model analysis showed rs28362491 was independently associated with increased IL-6 levels by analyses of a recessive model (P<0.001) after adjustment for covariates. CONCLUSIONS Our study indicates that NFKB1-94 ins/del ATTG polymorphism may play a role in CAD susceptibility in Chinese Uygur population and is functionally associated with IL-6 expression, suggesting a mechanistic link between NFKB1-94 ins/del ATTG polymorphism and CAD susceptibility.

Abstract
Behçet's disease (BD) is a chronic inflammatory autoimmune disease. Although raised levels of proinflammatory cytokines in BD have been reported, the pathogenesis is still unknown. The aim of this study was to investigate the association of NFKB1 and NFKBIA polymorphisms and their single and combined analysis effects on susceptibility of BD in Turkish population. We analysed the distribution of NFKB1 -94 ins/del ATTG (rs28362491) and NFKBIA 3' UTR A→G (rs696) polymorphisms using PCR-RFLP method in 89 patients with BD and 190 controls in this population. Statistical analysis of the results was performed by calculating OR, and 95% CI via χ(2) test and using Bonferroni correction. According to the significant results of both single and combined genotype analysis, the frequencies of ins/ins genotype and ins allele of rs28362491 were significantly higher in patients with BD (Pc = 0.003, 0.004, respectively). Also, higher frequencies of the rs696 variant containing AA genotype was found in patients with BD (Pc = 0.0033), whereas no statistical significant differences in distribution of the alleles of rs696 polymorphism in patients and controls. In addition, according to the combined genotype analysis, the wild type of both rs28362491 and rs696 polymorphisms (ins/ins/AA genotype) was also significantly higher in BD cases (Pc = 0.044). Our findings prove that both single and combined genotype analysis of rs28362491 and rs696 polymorphisms indicate that the wild genotypes of both two SNPs (ins/ins and AA genotypes) and ins/ins/AA combined genotype are strongly associated with enhanced risk of BD in a Turkish population.

Polymorphisms in NFKB1 and TLR4 and interaction with dietary and life style factors in relation to colorectal cancer in a Danish prospective case-cohort study. PLoS One 2015; 10:e0116394.

Abstract
Maintenance of a balance between commensal bacteria and the mucosal immune system is crucial and intestinal dysbiosis may be a key event in the pathogenesis of colorectal cancer (CRC). The toll-like receptor 4 (TLR4) is an important pattern-recognition receptor that regulates inflammation and barrier function in the gut by a mechanism that involves activation of the nuclear factor-κB (NF-κB) transcription factor. Dietary and life style factors may impact these functions. We therefore used a Danish prospective case-cohort study of 1010 CRC cases and 1829 randomly selected participants from the Danish Diet, Cancer and Health cohort to investigate three polymorphisms in NFKB1 and TLR4 and their possible interactions with diet and life style factors in relation to risk of CRC. Homozygous carriage of the variant allele of the TLR4/rs5030728 polymorphism was associated with increased risk of CRC (incidence rate ratio (IRR) = 1.30; 95% confidence interval (CI): 1.05-1.60; P = 0.02 (gene-dose model); IRR = 1.24; 95%CI: 1.01-1.51; P = 0.04 (recessive model)). Del-carriers of the NFKB1/rs28362491 polymorphism had a 17% (95%CI: 1.03-1.34; P = 0.02) increased risk of CRC compared to homozygous carriers of the ins-allele. However, none of these risk estimates withstood adjustment for multiple comparisons. We found no strong gene-environment interactions between the examined polymorphism and diet and life style factors in relation to CRC risk.

Abstract
Ulcerative colitis (UC) is a form of chronic and recurrent bowel disease with unknown etiology. Pieces of evidence suggest that UC should be evolved as a result of inappropriate and ongoing activation of the mucosal immune system driven by the luminal commensal microflora in a genetically susceptible host. Protein tyrosine phosphatase non-receptor type 2 (PTPN2) and nuclear factor-kappa B (NF-κB) play important roles not only in inflammatory pathways, but also in the development of UC. In recent years, association of PTPN2 and NF-κB gene polymorphisms with susceptibility to UC has become a research focus in Western counties, but the studies are controversial in southern China. This paper reviews the PTPN2 and NF-κB gene single nucleotide poly-morphisms (SNPs) associated with susceptibility to UC.

Abstract
Bacterial meningitis (BM) is a serious infection of the central nervous system, frequently occurring in childhood and often resulting in hearing loss, learning disabilities, and encephalopathy. Previous studies showed that genetic variation in innate immune response genes affects susceptibility, severity, and outcome of BM. The aim of this study is to describe whether single nucleotide polymorphisms (SNPs) in pathogen recognition gene products are associated with susceptibility to develop BM in single genes analysis as well as SNP combinations. Genotype frequencies of seven SNPs, in five immune response genes encoding for Toll-like receptors (TLRs), nucleotide oligomerization domain (NOD) proteins and caspase-1 (CASP1), in 391 children with meningococcal meningitis (MM) and 82 children with pneumococcal meningitis were compared with a large cohort of 1141 ethnically matched healthy controls. Carriage of TLR4 +896 GG mutant predisposed to susceptibility to develop MM (p = 1.2*10−5, OR = 9.4, 95% CI = 3.0–29.2). The NOD2 SNP8 mutant was significantly more frequent in MM patients compared to controls (p = 0.0004, OR = 12.2, 95% CI = 2.6–57.8). Combined carriage of TLR2 +2477 and TLR4 +896 mutants was strongly associated with MM (p = 4.2*10−5, OR = 8.6, 95% CI = 2.7–27.3). A carrier trait of TLR4 +896 and NOD2 SNP8 mutants was also strongly associated with susceptibility to develop MM (p = 4.2*10−5, OR = 10.6, 95% CI = 2.9–38.6). This study associates SNPs in TLR4 and NOD2 with susceptibility to develop MM.

Abstract
AIM: To clarify the association between a polymorphism -449 C>G (rs72696119) in 5’-UTR of NFKB1 with ulcerative colitis (UC).
METHODS: The studied population comprised 639 subjects, including patients with UC (UC cases, n = 174) and subjects without UC (controls, n = 465). We employed polymerase chain reaction-single strand conformation polymorphism to detect the gene polymorphism.
RESULTS: The rs72696119 G allele frequencies in controls and UC cases were 33.4% and 38.5%, respectively (P = 0.10). Genotype frequency of the GG homozygote in UC cases was significantly higher than that in controls (P = 0.017), and the GG homozygote was significantly associated with susceptibility to UC [odds ratio (OR), 1.88; 95%CI, 1.13-3.14]. In male subjects, the GG homozygote was associated with an increased risk for UC (OR, 3.10; 95%CI, 1.47-6.54; P = 0.0053), whereas this association was not found in female subjects. In addition, the GG homozygote was significantly associated with the risk of non-continuous disease (OR, 2.06; 95%CI, 1.12-3.79; P = 0.029), not having total colitis (OR, 2.40; 95%CI, 1.09-3.80, P = 0.040), disease which developed before 20 years of age (OR, 2.80; 95%CI, 1.07-7.32, P = 0.041), no hospitalization (OR, 2.28; 95%CI, 1.29-4.05; P = 0.0090) and with a maximum of 8 or less on the UCDAI score (OR, 2.45; 95%CI, 1.23-4.93; P = 0.022).
CONCLUSION: Our results provide evidence that NFKB1 polymorphism rs72696119 was significantly associated with the development of UC. This polymorphism influences the susceptibility to and pathophysiological features of UC.

Abstract
BACKGROUND The dimeric NF-κB transcription factors play critical roles in diverse cellular processes including adaptive and innate immunity, cell differentiation, proliferation and apoptosis. It regulates the expression of numerous genes that play a key role in the inflammatory response during kidney allograft rejection. This study aims to determine the association of NF-κB gene polymorphisms with allograft outcomes in the Hispanic renal transplant recipients. METHODS A total of 607 Hispanic renal transplant recipients at St. Vincent Medical Center between 2001 and 2010 were included in this study. The NF-κB genotypes were studied along with clinical data. In the case of NF-κB genotypes, the following single nucleotide polymorphisms (SNPs) were included: NF-κB1 (rs3774959, rs3774932, rs3774937, rs230526, rs230519), NF-κB2 (rs1056890, rs7897947, rs12769316) and NF-κB inducing kinase (NIK) (rs9908330, rs7222094). The association of each genotype with renal allograft survival and acute rejection was evaluated. RESULTS NF-κB1 (rs3774937) CC genotype showed protective association with allograft rejection (OR=0.66, 95% CI=0.44-0.99, p=0.04). There was a significant increase in allograft survival time associated with the NF-κB1 (rs3774959) A allele (OR=0.76, 95% CI=0.60-0.98, p=0.03) while GG genotype was associated with a higher risk of graft failure (OR=1.51, 95% CI=1.02-2.21, p=0.03). There were no associations between polymorphic markers in NF-κB2 and NIK genes with allograft survival or acute rejection. Among non-genetic factors, we found that the use of tacrolimus, a deceased donor, delayed graft function and acute rejection were associated with allograft failure. CONCLUSION The result of present study suggests that NF-κB1 gene polymorphisms may determine the incidence of acute rejection or graft survival among Hispanic allograft recipients.

Abstract
BACKGROUND Extensive investigation of the NF-κB1 -94ins/delATTG promoter polymorphism for risk association with ulcerative colitis (UC) and Crohn's disease (CD) risk has yielded conflicting results. AIMS The objective of this meta-analysis was to evaluate the risk association between the NF-κB1 -94ins/delATTG promoter polymorphism and UC and CD. METHODS All eligible case-control studies of the association of NF-κB1 -94ins/delATTG promoter polymorphism with UC and CD were identified in the Pubmed and Embase databases. From these data, odds ratios (OR) with 95 % confidence intervals (CI) were calculated. Meta-analysis was performed for alleles (D vs. W) and genotypes (DD + WD vs. WW, DD vs. WW + WD, DD vs. WW, WD vs. WW) in a fixed/random effects model. RESULTS Nine case-control studies that included 4,447 cases (2,631 UC and 1,816 CD) and 2,195 controls were identified. Results indicated increased risk association of D allele carriers with UC (D vs. W: OR = 1.08, 95 % CI = 1.01-1.17, P = 0.03; DD vs. WW + WD: OR = 1.16, 95 % CI = 1.01-1.32, P = 0.04 and DD vs. WW: OR = 1.20, 95 % CI = 1.03-1.39, P = 0.02). No risk association was identified with CD. CONCLUSION This meta-analysis indicated that the NF-κB1 -94ins/delATTG promoter polymorphism is a risk factor for UC but not CD.

Abstract
BACKGROUND AND AIMS An imbalance of Nuclear Factor Kappa B (NFкB) and Inhibitor Kappa B (IкB) is involved in various human diseases including atherogenesis. We aimed to evaluate the relationship between NFKB1 and NFKBIA polymorphism and susceptibility to myocardial infarction (MI). METHODS AND RESULTS Genotyping was performed for NFKB1 and NFKBIA gene variants in 253 subjects (86 patients affected by myocardial infarction and 167 control subjects). In 40 patients, biopsy specimens were taken from the left ventricle area of presumed ischemia for p50, p65 and IкBα quantification. The allele frequency and genotype distribution of NFKBIA gene polymorphism did not differ between MI and control group while control subjects had a higher D allele frequency of -94 ins/del ATTG NFKB1 polymorphism, compared to the MI group (P<0.001; OR=0.304; 95% CI=0.177-0.522). Subjects carrying the D allele had significantly lower plasma fibrinogen and CRP (C-reactive protein) levels compared to no carriers (P<0.05). Fibrinogen-genotype interaction was found to have a significant effect on susceptibility to myocardial infarction. Myocardial p50 (r=0.627; P=0.012) and p65 (r=0.683; P=0.005) levels significantly correlated with plasma fibrinogen levels while subjects carrying the D allele of the NFкB1 gene variant had lower myocardial p50 (P=0.007) and p65 (P=0.009) levels compared to no carriers. CONCLUSION -94 ins/del ATTG NFKB1 gene variant may contribute to lower MI susceptibility via the potential reduction of activated NFкB which in turn is related to plasma inflammatory marker reduction.

Abstract
Ulcerative colitis and Crohn's disease are chronic, immune-mediated inflammatory diseases of the gastrointestinal tract. Nuclear Factor Kappa B (NF-κB) is a transcription factor that plays a key role in regulating expression of multiple inflammatory and immune genes. In this study, a Topological Virtual Screening study has been carried out to achieve a model capable of finding new compounds active in ulcerative colitis by inhibiting NF-κB. Different topological indices were used as structural descriptors, and their relation to biological activity was determined using linear discriminant analysis. A topological model consisting of two discriminant functions was built up. The first function focused in the discrimination between NF-κB active and inactive compounds, and the second one in distinguishing between compounds active and inactive on ulcerative colitis. The model was then applied sequentially to a large database of compounds with unknown activity. Twenty-eight of such compounds were predicted to be active and selected for in vitro and in vivo testing.

Abstract
AIM: To investigate the contribution of polymorphisms in nuclear receptors to risk of inflammatory bowel disease (IBD).
METHODS: Genotypes of nuclear factor (NF)-κB (NFKB1) NFκB -94ins/del (rs28362491); peroxisome proliferator-activated receptor (PPAR)-γ (PPARγ) PPARγ Pro12Ala (rs 1801282) and C1431T (rs 3856806); pregnane X receptor (PXR) (NR1I2) PXR A-24381C (rs1523127), C8055T (2276707), and A7635G (rs 6785049); and liver X receptor (LXR) (NR1H2) LXR T-rs1405655-C and T-rs2695121-C were assessed in a Danish case-control study of 327 Crohn’s disease patients, 495 ulcerative colitis (UC) patients, and 779 healthy controls. Odds ratio (OR) and 95% CI were estimated by logistic regression models.
RESULTS: The PXR A7635G variant, the PPARγ Pro12Ala and LXR T-rs2695121-C homozygous variant genotypes were associated with risk of UC (OR: 1.31, 95% CI: 1.03-1.66, P = 0.03, OR: 2.30, 95% CI: 1.04-5.08, P = 0.04, and OR: 1.41, 95% CI: 1.00-1.98, P = 0.05, respectively) compared to the corresponding homozygous wild-type genotypes. Among never smokers, PXR A7635G and the LXR T-rs1405655-C and T-rs2695121-C variant genotypes were associated with risk of IBD (OR: 1.41, 95% CI: 1.05-1.91, P = 0.02, OR: 1.63, 95% CI: 1.21-2.20, P = 0.001, and OR: 2.02, 95% CI: 1.36-2.99, P = 0.0005, respectively) compared to the respective homozygous variant genotypes. PXR A7635G (rs6785049) variant genotype was associated with a higher risk of UC diagnosis before the age of 40 years and with a higher risk of extensive disease (OR: 1.34, 95% CI: 1.03-1.75 and OR: 2.49, 95% CI: 1.24-5.03, respectively).
CONCLUSION: Common PXR and LXR polymorphisms may contribute to risk of IBD, especially among never smokers.

Abstract
Ovarian cancer is the leading cause of death among all gynecological cancers. This is mainly attributed to its frequent presentation at an advanced stage (International Federation of Gynecology and Obstetrics stage III-IV). Nuclear factor-kappaB (NF-κB) is critically involved in the carcinogenesis and development of ovarian cancer. A functional insertion/deletion polymorphism (-94 ins/del ATTG) in the promoter region of the NFKB1 gene, which encodes the p50 subunit of the NF-κB protein, has been recently identified and shown to increase the susceptibility to many diseases. The purpose of this study was to explore the association between this polymorphism and the risk of advanced ovarian cancer in a Chinese population. A total of 179 advanced ovarian cancer patients and 223 healthy controls were recruited into this study. Genotypes were determined using polymerase chain reaction-capillary electrophoresis method. The insertion increased the risk of advanced ovarian cancer (odds ratio = 2.111, 95% confidence intervals = 1.125-3.961, p = 0.019 for heterozygote insertion, and odds ratio = 2.656, 95% confidence intervals = 1.397-5.051, p = 0.002 for homozygote insertion) compared with homozygote deletion. Similar results were seen in age-adjusted analyses (p < 0.05). Our preliminary results suggest that NFKB1-94 ins/del ATTG promoter polymorphism may be associated with increased susceptibility to advanced ovarian cancer.

Abstract
The human superorganism is a conglomerate of mammalian and microbial cells, with the latter estimated to outnumber the former by ten to one and the microbial genetic repertoire (microbiome) to be approximately 100-times greater than that of the human host. Given the ability of the immune response to rapidly counter infectious agents, it is striking that such a large density of microbes can exist in a state of synergy within the human host. This is particularly true of the distal gastrointestinal (GI) tract, which houses up to 1000 distinct bacterial species and an estimated excess of 1 x 10(14) microorganisms. An ever-increasing body of evidence implicates the GI microbiota in defining states of health and disease. Here, we review the literature in adult and pediatric GI microbiome studies, the emerging links between microbial community structure, function, infection and disease, and the approaches to manipulate this crucial ecosystem to improve host health.

Abstract
BACKGROUND AND OBJECTIVE Periodontitis is influenced by specific host-dependent immune responses. Periodontopathogens induce innate immune responses, amongst others, via toll-like receptor 2 (TLR2), resulting in activation of the nuclear transcription factor nuclear factor-kappaB (NF-kappaB). The aim of this case-control study was to evaluate links between genetic variants of these genes and chronic/aggressive periodontitis in a multivariate model. MATERIAL AND METHODS A total of 141 patients with periodontitis (63 with chronic periodontitis and 78 with aggressive periodontitis) and 81 controls without periodontitis were included in the study. Polymorphisms in TLR2 (Arg677Trp, Arg753Gln) and in NF-kappaB (-94ins/delATTG) were determined by restriction fragment length polymorphism and fragment length analyses, respectively. Subgingival bacterial colonization was evaluated using a PCR/DNA probe test (micro-Ident). RESULTS Although there was no association of the TLR2 polymorphism Arg753Gln with periodontitis, heterozygous carriers (Arg/Gln) were at a higher risk for colonization with bacteria of the 'red complex' (corrected p-value = 0.042). The del/del genotype of the NF-kappaB polymorphism was associated with aggressive periodontitis considering age, gender, smoking and approximal plaque index as potential confounders (odds ratio = 2.81, p = 0.035, 95% confidence interval: 1.08-7.33). del/del carriers had a higher risk for subgingival colonization with Aggregatibacter actinomycetemcomitans (odds ratio = 2.36, p = 0.030, 95% confidence interval: 1.09-5.1; adjusted for age, gender, smoking and pocket depth(bacteria)). CONCLUSIONS The del/del genotype of NF-kappaB was shown to be associated with the occurrence of aggressive periodontitis.

Abstract
BACKGROUND The era of genome-wide association studies (GWAS) has led to the identification of many inflammatory bowel disease (IBD)-associated single-nucleotide polymorphisms (SNPs) with unknown function. The next step would be to identify the functional consequences of these polymorphisms in order to target them efficiently for therapeutic purposes. One way to study this type of genetic variation is the use of cell line models. However, to characterize the functional effect of a SNP, it is important to know if the selected cell line model itself carries the studied genetic variation. Here, we genotyped 50 IBD markers across 32 susceptibility genes in 9 commonly used gastrointestinal cell lines. METHODS We used Sequenom, TaqMan, and DNA sequencing for the genotyping. To determine the expression profile of the selected genes, we conducted real-time RT-PCR. RESULTS We found variant SNPs in all analyzed cell lines. Almost every minor allele was carried by at least one of the tested cell lines. We analyzed the effect of 4 SNPs in more detail using quantitative real-time RT-PCR (qRT-PCR) comprising genes ATG16L1, CD14, MDR1, and OCTN2. According to our data, only 2 of the commonly studied SNPs in MDR1 and CD14 have an impact on gene expression. CONCLUSIONS We have identified genotype variants in all analyzed cell lines. Some of them are functional and alter the response to drugs (MDR1) or affect bacterial recognition (TLR4, NOD2). Our results highlight that the genotype should not be neglected in experimental design when using model cell lines.

Abstract
Nuclear factor (NF)-kappaB (NFKB1)-94ins/del is an important polymorphism that affects promoter activity of the NFKB1 gene and is potentially associated with several inflammatory diseases. We investigated the association of this polymorphism with lung injury after cardiac surgery and cardiopulmonary bypass in a prospective cohort study of 283 patients. Genotyping was performed by high resolution melting analysis; analysis indicated no association of NFKB1 with postoperative lung injury (p = 0.064). Relative risks of the del allele and the del/del genotype were 1.34 (95% CI 1.02-1.75) and 1.74 (95% CI 1.00-3.05) respectively. Logistic regression analysis (with factors including age, peripheral vascular disease and surgical duration as risk factors of lung injury after cardiac surgery with cardiopulmonary bypass) also failed to confirm that the NFKB1 genotype is influential for lung injury (p = 0.113). We conclude that, contrary to some other evidence, the NFKB1-94ins/del polymorphism is not associated with lung injury after cardiac surgery with cardiopulmonary bypass.

Abstract
BACKGROUND A very high expression of nuclear factor-kappa B protein (nuclear p50, encoded by NFKB1) in high-grade squamous intraepithelial lesion and invasive cancers has been observed. The aim of this study was to determine whether the functional NFKB1 -94 insertion/deletion ATTG polymorphism (rs28362491) is associated with cervical squamous cell carcinoma (CSCC). MATERIALS AND METHODS PCR-polyacrylamide gel electrophoresis method was used to genotype the NFKB1 -94 insertion/deletion ATTG polymorphism in 233 women with CSCC and 365 ethnicity-matched healthy control women. The genotyping method was confirmed by the DNA sequencing analysis. RESULTS The frequency of ATTG(2)/ATTG(2) genotype and ATTG(2) allele in the CSCC patients was significantly higher than that of controls, indicating that the -94 insertion/deletion ATTG polymorphism in NFKB1 promoter was associated with CSCC [P = 0.001, odds ratio (OR) = 2.560, 95% confidence interval (CI) 1.459-4.492 and P = 0.001, OR = 1.493, 95% CI 1.168-1.908, respectively]. Results of stratified analyses revealed that this polymorphism is associated with younger age (< or =35 years) and positive parametrial invasion but not with tumor differentiation, high clinical stage or lymph node status. CONCLUSION Our results indicate that the functional NFKB1 -94 insertion/deletion ATTG polymorphism is associated with CSCC, especially with younger age (< or =35 years) and positive parametrial invasion of CSCC patients.

Abstract
BACKGROUND The genetic basis for the predisposition to alcoholic liver cirrhosis (ALC) remains unknown. Increasing evidence supports a role for the nuclear factor (NF)-kappaB, the NF-kappaB inhibitor alpha (NFKBIA), and the peroxisome proliferator-activated receptor (PPAR)-gamma in the pathogenesis of alcoholic liver disease, raising the possibility that common polymorphisms in genes encoding these molecules may confer susceptibility to ALC. The objective of this study was to analyze the relationship between common polymorphisms in NFKB1, NFKBIA, and PPARG2 genes and the presence of ALC. METHODS A total of 258 male alcoholics (161 without liver disease and 97 with ALC) and 101 healthy controls were genotyped for the -94ins/delATTG NFKB1, 3'-UTR+126G>A NFKBIA, and 34C>G PPARG2 polymorphisms. The association of these genetic variants with ALC was tested in alcoholic patients with alcohol abuse and alcohol dependence. A logistic regression analysis was further performed to analyze the model of inheritance. RESULTS We found an association between the presence of the deletion allele in NFKB1 polymorphism and ALC in patients with alcohol dependence. We found no association between NFKBIA and PPARG2 polymorphisms and the presence of ALC. CONCLUSIONS The deletion allele of the -94ins/del NFKB1 polymorphism could be associated with a higher risk of developing ALC through an increase in inflammation, as supported by previous data.

Abstract
AIM: To investigate the association between NFkB1 -94ins/delATTG promoter polymorphism and ulcerative colitis in Chinese Han population of Hubei Province.
METHODS: The NFkB1-94ins/delATTG promoter polymorphism was genotyped in 73 unrelated Chinese patients with ulcerative colitis and 121 healthy controls using polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP). The correlation of allele and genotype frequencies for this locus with the clinical subtypes of ulcerative colitis was analyzed. The results were compared with those obtained in a previous study of Italian population.
RESULTS: No significant differences were found in genotype and allele frequencies of the NFkB1-94ins/delATTG promoter polymorphism between patients with ulcerative colitis and healthy controls. There was no significant correlation between allele and genotype frequencies for this locus and the clinical subtypes of ulcerative colitis (P > 0.05). However, the genotypes (χ2 = 13.155, P < 0.05) and allele frequencies (OR = 0.566, 95%CI: 0.413-0.774, P < 0.01) for this locus were significantly different between the Chinese and Italian populations.
CONCLUSION: No association between NFkB1 -94ins/delATTG promoter polymorphism and ulcerative colitis is found in Chinese Han population of Hubei Province.

Abstract
Background Previous studies in experimental and human heart failure showed that nuclear factor kappa B (NF-κB) is chronically activated in cardiac myocytes, suggesting an important involvement of NF-κB in the cardiac remodeling process. A common insertion/deletion (-94 insertion/deletion ATTG, rs28362491) located between two putative key promoter regulatory elements in the NFKB1 gene was identified which seems to be the first potential functional NFKB1 genetic variation. The main goal of the present investigation was to investigate the NFKB1 -94 insertion/deletion ATTG polymorphism in relation to risk of dilated cardiomyopathy (DCM). Methods A total of 177 DCM patients and 203 control subjects were successfully investigated. The NFKB1 -94 insertion/deletion ATTG polymorphism was genotyped by using PCR-PAGE. Results Genotype frequency of NFKB1 -94 insertion/deletion ATTG polymorphism in DCM patients was significantly different from that in control subjects (P = 0.015) and the ATTG2 carrier (ATTG1/ATTG2 + ATTG2/ATTG2) was susceptible to DCM. Conclusion Our data suggested that NFKB1 -94 insertion/deletion ATTG polymorphism is associated with DCM.

Abstract
We found that regular use of aspirin may reduce the risk of Hodgkin lymphoma (HL), a common cancer of adolescents and young adults in the United States. To explore possible biological mechanisms underlying this association, we investigated whether polymorphic variation in genes involved in nuclear factor-kappaB (NF-kappaB) activation and inhibition, other inflammatory pathways, and aspirin metabolism influences HL risk. Twenty single nucleotide polymorphisms (SNP) in seven genes were genotyped in DNA from 473 classical HL cases and 373 controls enrolled between 1997 and 2000 in a population-based case-control study in the Boston, Massachusetts, metropolitan area and the state of Connecticut. We selected target genes and SNPs primarily using a candidate-SNP approach and estimated haplotypes using the expectation-maximization algorithm. We used multivariable logistic regression to estimate odds ratios (OR) for associations with HL risk. HL risk was significantly associated with rs1585215 in NFKB1 (AG versus AA: OR, 2.1; 95% confidence interval, 1.5-2.9; GG versus AA: OR, 3.5; 95% confidence interval, 2.2-5.7, Ptrend=1.7x10(-8)) and with NFKB1 haplotypes (Pglobal=6.0x10(-21)). Similar associations were apparent across categories of age, sex, tumor EBV status, tumor histology, and regular aspirin use, although statistical power was limited for stratified analyses. Nominally significant associations with HL risk were detected for SNPs in NFKBIA and CYP2C9. HL risk was not associated with SNPs in IKKA/CHUK, PTGS2/COX2, UDP1A6, or LTC4S. In conclusion, genetic variation in the NF-kappaB pathway seems to influence risk of HL. Pooled studies are needed to detect any heterogeneity in the association with NF-kappaB across HL subgroups, including aspirin users and nonusers.

Abstract
PURPOSE In previous studies the NFKBIA 3'UTR (untranslated region) AA genotype was associated with Crohn's disease (CD), while the NFKB1-94ins/delATTG mutation increased the risk for ulcerative colitis (UC). The aim of our study was to investigate these two polymorphisms and patients' response to medical therapy and/or disease phenotype in Hungarian inflammatory bowel disease (IBD) patients. METHODS NFKBIA 3'UTR- and NFKB1-94ins/delATTG polymorphisms were investigated in 415 unrelated IBD patients (CD: 266 patients, mean age 35.2 +/- 12.1 years, duration 8.7 +/- 7.5 years; UC patients: 149, mean age 44.4 +/- 15.4 years, duration 10.7 +/- 8.9 years) and 149 controls by PCR-restriction fragment length polymorphism (RFLP) analysis. Detailed clinical phenotypes were determined by reviewing the medical charts. RESULTS The NFKBIA 3'UTR and NFKB1-94ins/delATTG genotypes and allele frequencies were not significantly different among IBD and controls. In patients with UC, the 3'UTR GG genotype was associated with extensive colitis (55.3 vs. 29.4%, odds ratio 2.97, 95% confidence interval 1.45-6.08). The presence of variant alleles did not predict response to steroids, infliximab, or need for surgery.
