Abstract
Aims: Breast cancer (BC) is one of the most common cancers among women. The influence of genetic variations on BC risk has been thus far assessed via genome-wide association studies. NF-κB has been recognized as a major player in BC progression. In this study, the association between rs28362491 and BC was evaluated in a population from northeastern Iran. Materials & methods: This study was conducted on 476 patients with BC and 524 healthy controls. The genotyping method used was an amplification-refractory mutation system. Results: The INS/DEL genotype conferred a statistically significant increased risk in patients in comparison with controls. Additionally, in the recessive model, INS/INS + INS/DEL versus DEL/DEL was statistically significant (OR = 0.34; 95% CI: 0.12-0.96; p = 0.042). Conclusion: This study found that rs28362491, as a susceptibility genetic factor, may affect BC risk in the Iranian population.

Wu H, Liang J. Contributions of NFKB1 -94insertion/deletion ATTG polymorphism to the susceptibility of gastrointestinal cancers: A meta-analysis. J Cell Mol Med 2021; 25:10674-10683. [PMID: 34672421 PMCID: PMC8581328 DOI: 10.1111/jcmm.17004] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Revised: 09/14/2021] [Accepted: 10/07/2021] [Indexed: 12/16/2022] Open
Abstract
Nuclear factor‐kappa B1 (NF‐κB1), a pleiotropic transcription factor, functions as a critical contributor to tumorigenesis. Growing numbers of case‐control studies were carried out to analyse the potential contribution of NF‐κB1 gene variants to gastrointestinal cancer risk, yet remains conflicting conclusions. Therefore, we conducted this most up‐to‐date meta‐analysis to evaluate the relationship between NF‐κB1 gene insertion (I)/deletion (D) polymorphism, namely −94ins/delATTG or rs28362491, and the susceptibility to gastrointestinal cancers. We searched PubMed, EMBASE and MEDLINE databases updated in April 2021 for relevant studies. Meta‐analysis was carried out by software Stata11.0. The quantification of the relationship was determined by computing the combined odds ratios (ORs) and their corresponding 95% confidence intervals (CIs). Sensitivity analysis, the funnel plot and Begg's rank correlation test were also applied. Our findings indicate that −94ins/delATTG polymorphism could not significantly impact the susceptibility to gastrointestinal cancers. Under any five genetic models, −94ins/delATTG polymorphism was not remarkedly linked to the risk of colorectal, gastric and oesophageal cancer, respectively. The significant role of −94ins/delATTG was only observed in some certain subgroups. Findings here suggest that NF‐κB1 gene −94ins/delATTG polymorphism may not predispose to gastrointestinal cancer susceptibility.

Abstract
As a cell survival signal, nuclear factor-kappa B (NFKB) is associated with the pathogenesis of numerous malignancies. According to several studies, NFKB1 −94ins/del ATTG promoter polymorphism is associated with the risk of different malignancies, but the results were not consistent. Therefore, we performed an updated meta-analysis based on 37 case-control studies from 33 articles (16,271 cases and 22,781 controls) to clarify the relationship. The odds ratio (OR) and 95% confidence interval (CI) were used to determine the strength of the association. We found that the NFKB1 −94ins/del ATTG promoter polymorphism was significantly associated with increased susceptibility to cancer in the recessive (II vs. ID+DD, OR = 1.140, 95% CI = 1.029–1.263, p =0.012), homozygote (II vs. DD, OR = 1.259, 95% CI = 1.068–1.485, p =0.006), and allele (I vs. D, OR = 1.109, 95% CI = 1.025–1.199, p =0.010) genetic models. The subgroup analysis for ethnicity found that the NFKB1 −94ins/del ATTG promoter polymorphism was significantly associated with an increased susceptibility to cancer in Asians and with a decreased susceptibility in Caucasians. The stratified analyses revealed significant associations between the polymorphism and increased susceptibility to ovarian cancer, oral squamous cell carcinoma, and nasopharyngeal carcinoma.

Abstract
Nuclear factor-kappa B1 (NF-κB1) is a pleiotropic transcription factor and key contributor to tumorigenesis in many types of cancer. Numerous studies have addressed the association of a functional insertion (I)/deletion (D) polymorphism (-94ins/delATTG, rs28362491) in the promoter region of NFKB1 gene with the risk of various types of cancer; however, their conclusions have been inconsistent. We therefore conducted a meta-analysis to reevaluate this association. PubMed, EMBASE, China National Knowledge infrastructure (CNKI), and WANFANG databases were searched through July 2016 to retrieve relevant studies. After careful assessment, 50 case-control studies, comprising 18,299 cases and 23,484 controls were selected. Crude odds ratios (ORs) and 95% confidence intervals (CIs) were used to determine the strength of the association. The NFKB1 -94ins/delATTG polymorphism was associated with a decreased risk of overall cancer in the homozygote model (DD vs. II): OR = 0.75, 95% CI = 0.64-0.87); heterozygote model (ID vs. II): OR = 0.91, 95% CI = 0.83-0.99; recessive model (DD vs. ID/II): OR = 0.81, 95% CI = 0.71-0.91; dominant model (ID/DD vs. II): OR = 0.86, 95% CI = 0.78-0.95; and allele contrast model (D vs. I): OR = 0.88, 95% CI = 0.81-0.95). Subgroup and stratified analyses revealed decreased risks for lung cancer, nasopharyngeal carcinoma, prostate cancer, ovarian cancer, and oral squamous cell carcinoma, and this association held true also for Asians (especially Chinese subjects) in hospital-based studies, and in studies with quality scores less than nine. Well-designed, large-scale case-control studies are needed to confirm these results.

Abstract
BACKGROUND Melanoma is the leading cause of death from skin cancers and its etiology is complex. Recent discoveries related to genetic risk factors are helping us to understand melanoma pathogenesis better. Nuclear factor-κB (NF-κB) has a critical role in immunity, inflammation, and tumor growth. The 94ins/del ATTG (rs28362491) polymorphism located in the NFKB1 gene has been associated to various cancers and the ATTG2/ATTG2 genotype was correlated to melanoma risk in Sweden. The CYP19A1 gene encodes the enzyme aromatase, which is active in malignant melanoma tissue. In addition, the CYP19A1 TCT insertion/deletion variant in intron 4 (rs11575899) has been associated with an increased incidence of cancer, albeit with conflicting results. The goal of this study was to investigate possible associations between these two gene variants and melanoma. METHODS In this case-control study, we evaluated 117 cutaneous melanoma patients and 116 controls from southern Brazil. Genotyping of rs28362491 and rs11575899 was carried out by means of PCR amplification and capillary electrophoresis. Logistic regression was used to obtain odds ratios (ORs) of melanoma, according to genotypes. RESULTS We identified an association between the ATTG2/ATTG2 and melanoma [OR=1.78; 95% confidence interval (CI): 1.06-3.00; P=0.03]. In addition, there was a dose effect: for each ins allele in the genotype, the risk for melanoma increased (OR=1.51; 95% CI: 1.08-2.11; P=0.017). As regards the CYP19A1 variant, genotype 11 (del/del) was more frequent in patients than in controls (OR=1.85; 95% CI 1.06-3.22; P=0.03). CONCLUSION The NFKB1 ATTG2/ATTG2 and CYP19A1 del/del genotypes are significantly associated with melanoma and could be genetic markers of melanoma susceptibility in southern Brazilian population.

Abstract
Background NFKBIA encodes the inhibitors of nuclear factor-κB (NF-κB), which regulate the translation of the genes involved in the inflammatory and immune reactions. Polymorphisms (rs2233406, rs3138053, and rs696) of NFKBIA have been implicated in susceptibility to many cancer types. Material/Methods To evaluate the association between polymorphisms of NFKBIA and cancer susceptibility, a meta-analysis including a total of 7182 cancer cases and 10 057 controls from 28 case-control studies was performed. Data were extracted and pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Results Combined data demonstrated that rs3138053 polymorphism of NFKBIA was associated with cancer susceptibility in an allelic model (C vs. T: OR=10.754, 95%CI=4.175–27.697, Pheterogeneity=0.000), while the polymorphism of rs696 appeared to play a protective role in tumorigenesis (CC+CT vs. TT: OR=0.879, 95%CI=0.787–0.982, Pheterogeneity=0.107). When stratification analysis was performed by cancer type, an increased association of rs3138053 was recognized in hepatocarcinoma (C vs. T: OR=42.180, 95%CI=27.970–63.612, Pheterogeneity=0.007), while a decreased association of rs696 was identified in Hodgkin lymphoma (C vs. T: OR=0.792, 95%CI=0.656–0.956, Pheterogeneity=0.116; CC vs. TT: OR=0.658, 95%CI=0.448–0.965, Pheterogeneity=0.076; CC vs. CT+TT: OR=0.734, 95%CI=0.562–0.958, Pheterogeneity=0.347). By ethnicity, rs696 appears to be a protective candidate among Caucasians (CT vs. TT: OR=0.809, 95%CI=0.676–0.969, Pheterogeneity=0.459). Conclusions Our data demonstrated that the rs3138053 polymorphism of NFKBIA gene is a candidate for susceptibility to overall cancers, while rs696 plays a protective role.

Role of genetic polymorphisms in NFKB-mediated inflammatory pathways in response to primary chemoradiation therapy for rectal cancer. Int J Radiat Oncol Biol Phys 2014; 90:595-602. [PMID: 25304949 DOI: 10.1016/j.ijrobp.2014.06.060] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2014] [Revised: 05/20/2014] [Accepted: 06/23/2014] [Indexed: 12/20/2022]
Abstract
PURPOSE To investigate whether polymorphisms of genes related to inflammation are associated with pathologic response (primary endpoint) in patients with rectal cancer treated with primary chemoradiation therapy (PCRT). METHODS AND MATERIALS Genomic DNA of 159 patients with locally advanced rectal cancer treated with PCRT was genotyped for polymorphisms rs28362491 (NFKB1), rs1213266/rs5789 (PTGS1), rs5275 (PTGS2), and rs16944/rs1143627 (IL1B) using TaqMan single nucleotide polymorphism genotyping assays. The association between each genotype and pathologic response (poor response vs complete or partial response) was analyzed using logistic regression models. RESULTS The NFKB1 DEL/DEL genotype was associated with pathologic response (odds ratio [OR], 6.39; 95% confidence interval [CI], 0.78-52.65; P=.03) after PCRT. No statistically significant associations between other polymorphisms and response to PCRT were observed. Patients with the NFKB1 DEL/DEL genotype showed a trend for longer disease-free survival (log-rank test, P=.096) and overall survival (P=.049), which was not significant in a multivariate analysis that included pathologic response. Analysis for 6 polymorphisms showed that patients carrying the haplotype rs28362491-DEL/rs1143627-A/rs1213266-G/rs5789-C/rs5275-A/rs16944-G (13.7% of cases) had a higher response rate to PCRT (OR, 8.86; 95% CI, 1.21-64.98; P=.034) than the reference group (rs28362491-INS/rs1143627-A/rs1213266-G/rs5789-C/rs5275-A/rs16944-G). Clinically significant (grade ≥2) acute organ toxicity was also more frequent in patients with that same haplotype (OR, 4.12; 95% CI, 1.11-15.36; P=.037). CONCLUSIONS Our results suggest that genetic variation in NFKB-related inflammatory pathways might influence sensitivity to primary chemoradiation for rectal cancer. If confirmed, an inflammation-related radiogenetic profile might be used to select patients with rectal cancer for preoperative combined-modality treatment.

Abstract
To assess the effect of the NFKB1 -94ins/del polymorphism on cancer, we conducted a meta-analysis based on 25 studies including 8,750 cases and 9,170 controls. Overall, the -94ins/del polymorphism was associated with cancer risk in the pooled analysis and in Asian population, whereas no association was observed in Caucasian population. Stratified analysis by subtypes of cancer showed that the -94ins/del polymorphism was associated with oral squamous cell carcinoma and ovarian cancer risk, but had no association with colorectal cancer, bladder cancer, and renal cell cancer. Our meta-analysis suggests the NFKB1 -94ins/del polymorphism affects cancer susceptibility, and the association is ethnic-specific.

Nuclear factor-κB is associated with the pathogenesis of numerous malignancies, and the functional polymorphism −94ins/del ATTG (rs28362491) in the human NFKB1 gene is associated with cancer risk. Previous studies on the association between the −94ins/del ATTG polymorphism and cancer risk reported conflicting results. To clarify this relationship, we performed a meta-analysis of 21 case-control studies involving 6127 cases and 9238 controls. We used pooled odds ratios (ORs) with their 95% confidence intervals (95% CIs) to assess the association. We found that the NFKB1 promoter −94ins/del ATTG polymorphism was significantly associated with cancer risk in four genetic models (ins/ins versus del/del, OR = 1.47, 95% CI = 1.11–1.93; dominant model, OR = 1.26, 95% CI = 1.03–1.53; recessive model, OR = 1.26, 95% CI = 1.05–1.51; ins allele versus del allele, OR = 1.19, 95% CI = 1.05–1.35). Stratified analyses revealed a significant association between the polymorphism and ovarian, oral, and prostate cancers. Similar results were determined in an Asian population and not in a Caucasian population. Thus, our results suggested that the polymorphism can contribute to cancer risk. Moreover, the polymorphism can exert race- and cancer-specific effects on cancer risk. Further large-scale and functional studies are necessary to elucidate this possible effect.

Investigation of NF-κB1 and NF-κBIA gene polymorphism in non-small cell lung cancer. BIOMED RESEARCH INTERNATIONAL 2014; 2014:530381. [PMID: 24707489 PMCID: PMC3953471 DOI: 10.1155/2014/530381] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/20/2013] [Revised: 12/13/2013] [Accepted: 01/09/2014] [Indexed: 01/23/2023]
Abstract
Lung cancer is a complex, multifactorial disease which is the leading cause of cancer death in both men and women.
NF-κB is a transcription factor which is known to affect the expression of more than 150 genes related to inflammation, lymphocyte activation, cell proliferation, differentiation, and apoptosis, as well as contributing to cell apoptosis and survival. However, NF-κBIA (IκBα) is the inhibitor of the transcription factor. The -94ins/delATTG polymorphism of the NF-κB1 gene promoter region which causes a functional effect and NF-κBIA 3′UTR A → G polymorphism has been shown to be related to various inflammatory diseases and cancer. Ninety-five NSCLC patients and 99 healthy controls were included in study. The NF-κB1 -94ins/delATTG and NF-κBIA 3′UTR A → G polymorphism have been studied by using PCR-RFLP method. It was found that the NF-κB1 -94ins/delATTG DD genotype and D allele frequencies were higher in patients than healthy controls and the presence of the DD genotype has a 3.5-fold increased risk of the disease (P: 0.014). This study is the first to investigate the NF-κB1 -94ins/delATTG and NF-κBIA 3′UTR A → G polymorphism together in the Turkish population. According to the results, the NF-κB1 -94ins/del ATTG promoter polymorphism may have a role in lung carcinogenesis and prognosis.

NFKB1 -94 insertion/deletion polymorphism and cancer risk: a meta-analysis. Tumour Biol 2014; 35:5181-7. [PMID: 24532467 DOI: 10.1007/s13277-014-1672-z] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2013] [Accepted: 01/22/2014] [Indexed: 12/11/2022] Open
Abstract
Previous studies on the associations of the NFKB1 -94 insertion/deletion polymorphism with cancer risk have produced conflicting results. The purpose of this meta-analysis is to define the effect of the NFKB1 -94 insertion/deletion polymorphism on cancer risk. A search of the literature by PubMed was performed to identify studies based on the predetermined inclusion criteria. Twenty-three studies consisting of 6,494 cases and 9,884 controls were identified and analyzed. Overall, significant association was observed between the polymorphism and cancer risk under all genetic models. Subgroup analysis according to ethnicity and cancer type also detected significant association. The NFKB1 -94 insertion/deletion polymorphism was associated with cancer risk in Asian population (dominant model: OR=1.52, 95 % CI=1.17-1.98; recessive model: OR=1.50, 95 % CI=1.26-1.79; II vs. DD: OR=1.90, 95 % CI=1.37-2.65; ID vs. DD: OR=1.32, 95 % CI=1.05-1.66; I vs. D: OR=1.37, 95 % CI=1.17-1.60), but not in Caucasian population. In addition, significant associations in OC, HCC, and OSCC were observed, but significant associations were not found in BC and LC. The current meta-analysis suggested that NFKB1 -94 insertion/deletion polymorphism may influence cancer risk in Asian population.

Abstract
Background Tumour necrosis factor-alpha (TNF-α) and nuclear factor of kappa light chain gene enhancer in activated B cells (NF-κB) play critical role in carcinogenesis processes like tumour initiation, proliferation, migration and invasion. Single nucleotide polymorphisms in TNF-α, NF-κB and its inhibitor IκB genes were shown to be associated with susceptibility and prognosis of several cancers; however, their role in esophageal squamous cell carcinoma (ESCC) is not well recognised. Therefore, in present study, we aimed to investigate association of common polymorphisms in TNFA, NFkB1 and NFKBIA with risk and prognosis of ESCC in northern Indian population. Methods We genotyped 290 ESCC patients (including 162 followed up cases) and 311 mean age, gender and ethnicity matched controls for TNFA -308G>A, NFkB1 -94ATTG ins/del and NFKBIA (-826C>T and 3’UTRA>G) polymorphisms using PCR alone or followed by RFLP and TaqMan assay. Results TNFA-308GA genotype was associated with increased risk of ESCC specifically in females and in patients with regional lymph node involvement, while, NFKBIA -826CT+TT genotype conferred decreased risk of ESCC in females. Haplotypes of NFKBIA -826C>T and 3’UTRA>G polymorphisms, C-826G3’UTR and T-826A3’UTR, were associated with reduced risk of ESCC. No independent role of NFkB1 -94ATTG ins/del polymorphism in susceptibility of ESCC was found. Multi-dimensionality reduction analysis showed three factor model TNFA-308, NFKBIA-826, NFKBIA 3’UTR as better predictor for risk of ESCC. Furthermore, combined risk genotype analysis of all studied polymorphisms showed increased risk of ESCC in patients with 1-3 risk genotype compared to ‘0’ risk genotype. Survival analysis did not show any significant prognostic effect of studied polymorphisms. However, in stepwise multivariate analysis, metastasis was found to be independent prognostic predictor of ESCC patients. Conclusion TNFA-308 and NFKBIA (-826C>T and 3’UTRA>G) polymorphisms may play role in susceptibility but not in prognosis of ESCC patients in northern Indian population.

Abstract
In the present study, we report an association between gastric cancer and polymorphisms in NFKB1 (rs28362941 and rs78696119). We employed the PCR-SSCP method to detect gene polymorphisms in 479 gastric cancer cases and 880 controls. The rs28362941 del/del homozygote was significantly associated with gastric cancer development; in particular it was closely associated with diffuse type gastric cancer. The rs78696119 GG homozygote was also associated with the diffuse type of gastric cancer. In young subjects, both polymorphisms were significantly associated with the development of gastric cancer. In addition, both polymorphisms were related to tumor progression such as tumor invasion and lymph node metastasis. The inflammatory cell infiltration into non-cancerous gastric mucosa was greater in the subjects with the rs28362491 del/del or rs78696119 GG genotype when compared to those with the other genotypes. In conclusion, functional polymorphisms of NFKB1 are associated with an increased risk of gastric cancer; in particular they are closely associated with the development of diffuse type of gastric cancer via severe gastric inflammation. These polymorphisms also appear to be associated with gastric cancer progression.

Abstract
BACKGROUND Constitutive activation of nuclear factor (NF)-κB is frequently observed in hepatocellular carcinoma (HCC). The current study examined associations of polymorphisms within promoter regions of NFKB1 encoding NF-κB1 and NFKBIA encoding IκBα with the susceptibility of developing HCC and clinicopathological characteristics of the tumors. METHODOLOGY AND PRINCIPAL FINDINGS Genetic polymorphisms of NFKB1 and NFKBIA were analyzed by a real-time polymerase chain reaction (PCR) in 135 HCC patients and 520 healthy controls. The genotypic frequency of the NFKB1 -94 Ins polymorphism in HCC patients was significantly higher than that of the controls (adjusted odds ratio (AOR) = 2.23; 95% confidence interval (CI) 1.32∼3.77). No statistical significance was observed for the distribution frequency of the NFKBIA --519 C/T, -826 C/T, or -881 A/G genotype and haplotype polymorphisms between HCC patients and controls. Furthermore, female HCC patients carrying the NFKB1 -94 Ins polymorphism were associated with lower clinical stages and smaller tumor sizes. CONCLUSIONS Our results indicate that the NFKB1 -94 Ins promoter polymorphism increased the risk of HCC, and may be applied as a predictive factor for the clinical stage and tumor size in female HCC patients.

Abstract
Congenital heart disease (CHD) is the most frequently occurring congenital disorder in newborns and is the most frequent cause of infant death from birth defects. Human genetic studies have identified that numerous genes encoding transcription factors that regulate specific events in heart development are responsible for inherited and sporadic CHD. Nuclear factor-kappa B (NF-κB) is a major transcription regulator of immune response, apoptosis and cell-growth control genes. The aim of this study was to investigate whether the functional -94 insertion/deletion ATTG polymorphism (rs28362491) in the promoter of nuclear factor κB gene (NFKB1) is associated with susceptibility to CHD. Polymerase chain reaction (PCR)-polyacrylamide gel electrophoresis (PAGE) method was used to genotype rs28362491 in 122 atrial septal defect (ASD) patients, 114 ventricular septal defect (VSD) patients, and 412 controls. The frequencies of II (Insertion/Insertion) genotype in the ASD and VSD patients were significantly higher than that of controls (p=0.004 for ASD Vs. controls, and p=0.009 for VSD Vs. controls, respectively), and the frequencies for I allele in CHD patients were also significantly higher than that in controls (p=0.01 for ASD Vs. controls, and p=0.009 for VSD Vs. controls, respectively). This study suggests that the functional -94 insertion/deletion ATTG polymorphism in the promoter of NFKB1 is associated with CHD.

Abstract
OBJECTIVE Activated nuclear factor-ĸB is associated with the pathogenesis of numerous malignancies, including renal cell carcinoma (RCC). This study aimed to clarify the influence of a common insertion/deletion polymorphism (-94 ins/del ATTG, rs28362491) in the NFKB1 promoter on RCC susceptibility. METHODS We genotyped the NFKB1 -94 ins/del ATTG promoter polymorphism by the TaqMan method and assessed the association with RCC risk, clinicopathological parameters in a case-control study of 1,027 cases and 1,094 controls. RESULTS The genotype frequencies were significantly different between RCC cases and controls (p = 0.046). Compared with individuals carrying the ins/del + del/del genotypes, those with the ins/ins genotype had an increased RCC risk [p = 0.036, adjusted odds ratio (OR) = 1.23, 95% confidence interval (CI) = 1.02-1.48], particularly in the subgroup of younger age (p = 0.005, adjusted OR = 1.42, 95% CI = 1.11-1.83) and never smokers (p = 0.013, adjusted OR = 1.34, 95% CI = 1.07-1.69). Furthermore, the polymorphism was significantly associated with the risk of developing localized stage RCC (p = 0.020, OR = 1.26, 95% CI = 1.04-1.53). CONCLUSIONS The functional NFKB1 promoter polymorphism is associated with an increased risk of RCC.

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
CpG island aberrant methylation is shown to be an important mechanism in gene silencing. The important role of NF-κB in the inflammatory response to H. pylori colonization has been indicated. We investigated the influence of NFKB1 polymorphisms, -94 ins/del (rs28362491) and -449 C>G (rs72696119), on the aberrant gene methylation under H. pylori infection. Gastric mucosal samples were obtained from sub-subjects without malignancies. Methylation status of genes (p14ARF, p16INK4a, DAPK and CDH1) was determined by methylation-specific PCR (MSP). The genotyping of NFKB1 was performed by PCR-SSCP. There was a strong allelic association between rs28362491 and rs72696119, and all H. pylori-infected -94 del/del homozygotes had a -449 GG genotype. The -94 del/del homozygosity was significantly associated with risk for development of CpG island high methylation (CIHM) (two or more gene methylations), especially DAPK and CDH1 methylations, and the number of methylated genes was significantly higher in -94 del/del homozygotes than in ins/del and ins/ins (ins carrier) H. pylori-infected elder subjects. In addition, this methylated gene number was significantly increased with age in H. pylori-infected del/del homozygotes, but not in infected ins carriers. Furthermore, the inflammation score was significantly higher in H. pylori-infected del/del homozygotes compared to ins carriers. NFKB1 -94 ins/del ATTG polymorphism (rs28362491) was significantly associated with the increased risk for the development of age-related gene methylation in non-cancerous gastric mucosa under H. pylori-induced inflammation.

Abstract
Due to the high morbidity and mortality of colorectal cancer (CRC), this study aims to determine the joint association of RE-1-silencing transcription factor (REST) and nuclear factor-κB 1 (NFKB1) genes with CRC in a population-based study. A well-matched case-control study including 390 controls and 388 patients with CRC was enrolled in China. The selected single nucleotide polymorphisms (SNPs) in the REST and NFKB1 genes were genotyped by Illumina SnapShot Chip. After adjustment for important covariates, the associations of SNPs and joint association of REST and NFKB1 with CRC were evaluated by multiple logistic regression models. The subjects with the rs2228991 AA genotype of the REST gene had a decreased risk for CRC (OR = 0.38; 95%CI: 0.19-0.74), compared with the GG genotype. There were no significant associations between three SNPs in the NFKB1 gene, their haplotype and CRC risk. However, a significant combined effect of rs3774959 and rs3774964 in the NFKB1 gene with rs2228991 in the REST gene on CRC risk was observed. In conclusion, the present study found that mutation in the REST gene rather than the NFKB1 gene was associated with the risk of CRC. Furthermore, significant REST-NFKB1 joint association was observed for CRC, colon cancer and rectal cancer risk.

Abstract
It is only recently that the full importance of nuclear factor-κB (NF-κB) signalling to cancer development has been understood. Although much attention has focused on the upstream pathways leading to NF-κB activation, it is now becoming clear that the inhibitor of NF-κB kinases (IKKs), which regulate NF-κB activation, have many independent functions in tissue homeostasis and normal immune function that could compromise the clinical utility of IKK inhibitors. Therefore, if the NF-κB pathway is to be properly exploited as a target for both anticancer and anti-inflammatory drugs, it is appropriate to reconsider the complex roles of the individual NF-κB subunits.

Abstract
Population-based studies are important to address emerging issues in health disparities among populations. The Partnership between the Moffitt Cancer Center (MCC) in Florida and the Ponce School of Medicine and Health Sciences (PSMHS) in Puerto Rico (the PSMHS-MCC Partnership) was developed to facilitate high-quality research, training, and community outreach focusing on the Puerto Rican population in the island and in the mainland, with funding from the National Cancer Institute. We report here the establishment of a Tissue Biobank at PSMHS, modeled after the MCC tissue biorepository, to support translational research projects on this minority population. This facility, the Puerto Rico Tissue Biobank, was jointly developed by a team of basic and clinical scientists from both institutions in close collaboration with the administrators and clinical faculty of the tissue accrual sites. The efforts required and challenges that needed to be overcome to establish the first functional, centralized cancer-related biobank in Puerto Rico, and to ensure that it continuously evolves to address new needs of this underserved Hispanic population, are described. As a result of the collaborative efforts between PSMHS and MCC, a tissue procurement algorithm was successfully established to acquire, process, store, and conduct pathological analyses of cancer-related biospecimens and their associated clinical-pathological data from Puerto Rican patients with cancer recruited at a tertiary hospital setting. All protocols in place are in accordance with standard operational procedures that ensure high quality of biological materials and patient confidentiality. The processes described here provide a model that can be applied to achieve the establishment of a functional biobank in similar settings.
