Association of Four Interleukin-8 Polymorphisms (-251 A>T, +781 C>T, +1633 C>T, +2767 A>T) with Ovarian Cancer Risk: Focus on Menopausal Status and Endometriosis-Related Subtypes. Biomedicines 2024; 12:321. [PMID: 38397923 PMCID: PMC10886609 DOI: 10.3390/biomedicines12020321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 01/22/2024] [Accepted: 01/27/2024] [Indexed: 02/25/2024] Open
Abstract
Interleukin-8 (IL-8) is involved in the regulation of inflammatory processes and carcinogenesis. Single-nucleotide polymorphisms (SNPs) within the IL-8 gene have been shown to alter the risks of lung, gastric, or hepatocellular carcinomas. To date, only one study examined the role of IL-8 SNPs in ovarian cancer (OC), suggesting an association between two IL-8 SNPs and OC risk. In this study, we investigated four common IL-8 SNPs, rs4073 (-251 A>T), rs2227306 (+781 C>T), rs2227543 (+1633 C>T), and rs1126647 (+2767 A>T), using the restriction fragment length polymorphism (PCR-RFLP) technique. Our study included a cohort of 413 women of Central European descent, consisting of 200 OC patients and 213 healthy controls. The most common (73.5%) histological type was high-grade serous OC (HGSOC), whereas 28/200 (14%) patients had endometriosis-related (clear cell or endometrioid) OC subtypes (EROC). In postmenopausal women, three of the four investigated SNPs, rs4073 (-251 A>T), rs2227306 (+781 C>T), and rs2227543 (+1633 C>T), were associated with OC risk. Furthermore, we are the first to report a significant relationship between the T allele or TT genotype of SNP rs1126647 (+2767 A>T) and the EROC subtype (p = 0.02 in the co-dominant model). The TT homozygotes were found more than twice as often in EROC compared to other OC subtypes (39% vs. 19%, p = 0.015). None of the examined SNPs appeared to influence OC risk in premenopausal women, nor were they associated with the aggressive HGSOC subtype or the stage of disease at the initial diagnosis.

Dashtaki ME, Karimi E, Ghasemi S. Genetic Variants Impacting Angiogenesis Signaling Pathways in Glioblastoma Multiforme: A Systematic Review of Mutations and Polymorphisms. Curr Mol Med 2024; 24:1346-1357. [PMID: 37489777 DOI: 10.2174/1566524023666230725115812] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Revised: 06/11/2023] [Accepted: 06/19/2023] [Indexed: 07/26/2023]
Abstract
BACKGROUND Several signaling pathways are involved in the process of angiogenesis, which is one of the most important hallmarks of glioblastoma multiforme (GBM). Identifying related gene variants can help researchers work out what causes anti-angiogenesis drug resistance. OBJECTIVE The goal of this systematic analysis was to identify all mutations and polymorphisms involved in angiogenesis pathways in GBM and their impact on clinical outcomes. METHODS The keywords include glioblastoma, angiogenesis, signaling pathway, mutation, polymorphism, and related terms used to search ISI, PubMed, and Scopus for relevant articles published up to January 2022. The PRISMA protocol was used to conduct our systematic review. The related articles were taken into consideration. The risk of bias in the associated articles was surveyed, as well as the article scoring. Two authors collaborated on data extraction. RESULTS The inclusion criteria were included in 32 articles out of a total of 787 articles. VEGF, HIF1a, EGFR, PI3K, and MAPK are the pathways that have been studied the most. IDH1, VEGF, VEGFR, EGFR, and HIF1a are the genes with the highest frequency of mutations or polymorphisms. CONCLUSION In conclusion, this study found that angiogenesis in primary or recurrent GBM is linked to gene changes in eleven signaling pathways. However, some of these gene mutations have been researched numerous times in relation to angiogenesis, while others have only been studied once. Understanding these changes will help us employ combination therapies more effectively for GBM patients' survival and personal medicine.

Investigation of roles of IL-8 (+ 781 C/T) and MMP-2 (-735 C/T) gene variations in early diagnosis of bladder cancer and progression. Mol Biol Rep 2023; 50:443-451. [PMID: 36348195 DOI: 10.1007/s11033-022-07881-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 08/12/2022] [Accepted: 08/17/2022] [Indexed: 11/09/2022]
Abstract
BACKGROUND The aim of our study is to investigate the roles of IL-8 (+ 781 C/T) and MMP-2 (-735 C/T) gene variations in early diagnosis and progression of BCA. METHODS Polymerase chain reaction (PCR) followed by restriction fragment length polymorphism (RFLP) methods were used to determine the genotype distributions of IL-8 (+ 781 C/T) and MMP-2 (-735 C/T) gene variations. RESULTS In our study, the genotype distributions of IL-8 (+ 781 C/T) and MMP-2 (-735 C/T) gene variations were not found to be significantly different between the patient and control groups. In addition, C and T allele frequencies for these gene variations were not different from the Hardy-Weinberg distribution in patient and control groups. However, when the combined genotype analyzes for these gene variations were evaluated, CC-CC and CT-CC combined genotypes for + 781 C/T / -735 C/T gene variations were observed significantly more in the patient group compared to other genotypes. CONCLUSION Although IL-8 (+ 781 C/T) and MMP-2 (-735 C/T) gene variations were not found to be genetic risk factors in the Thrace population in our study, CC-CC and CT-CC combined genotypes were determined as genetic risk factors for BCA susceptibility. The combined genotypes obtained as a result of the combined genotype analysis of these genetic variations that are effective in tumor progression may be considered to be important biomarkers for the early diagnosis and progression of BCA.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE) susceptibility was found to be correlated with genetic polymorphisms. Therefore, the current study aimed to investigate the association of the IL-8-251 T/A polymorphism with the risk of SLE. METHODS A total of 135 SLE patients and 75 controls were enrolled in our study. The IL-8-251 T/A polymorphism was analysed by PCR-RFLP. Also, the serum concentration of IL-8 was measured using ELISA. Finally, investigate possible IL-8 pathways in SLE pathogenesis by using the STRING database. RESULTS Our results revealed that the risk of having SLE in AA genotype carriers was significantly increased (OR = 1.92, 95 % CI = 1.23-3.10, p = 0.006) when compared with TT genotype carriers. Patients with SLE had a significantly higher frequency of the A allele (OR = 1.37, 95 % CI = 1.09-1.7; P = 0.01) than controls. Serum IL-8 levels were significantly increased in SLE patients (77.81 ± 21.27; p < 0.001) when compared to healthy controls (48.85 ± 7.89). Also, it was found that the serum IL-8 level had significant positive correlations with proteinuria, ESR, ANA, urea and SELADI, and significant negative correlations with RBCs count, C3 and hemoglobin. According to ROC curve analysis, serum IL-8 levels are a good biomarker for the detection of SLE disease, with 87.5 % sensitivity and 85 % specificity. STRING analysis revealed that IL-8 interacts with key SLE signaling pathway members such as TNF-α, IL-1β, IL-6, and IL-10. CONCLUSIONS There was a correlation between the IL-8-251 T/A polymorphism and the risk of SLE. Our findings also suggest that the IL8-251 A allele may be an important risk factor for the development of SLE.

Abstract
Simple Summary Neuroblastoma (NB) presents diverse biological and clinical characteristics, from spontaneous regression to highly malignant and aggressive unfavorable tumors that condition the therapeutic failure of conventional treatments. The tumorigenesis of NB can be the result of different genetic variants, which can influence the clinical outcome, and the survival of patients who have metastatic tumors is low. The role of cytokines such as interleukin (IL)-6 has been described in the NB microenvironment promoting tumor progression and metastasis. Single nucleotide polymorphism (SNP)-174 G > C in IL-6 and -251 T > A and +781 C > T in IL-8 regulate the expression of these cytokines, and could be associated with the clinical outcome in patients with NB. Our objective was to evaluate the association of the genetic polymorphisms of IL-6 and IL-8, as well as the serum levels of these cytokines in patients with NB, as this will allow the genetic bases of NB to be characterized and understood, in order to predict the outcome of the disease and develop new therapeutic strategies. Abstract There is evidence that high circulating levels of IL-6 and IL-8 are markers of a poor prognosis in various types of cancer, including NB. The participation of these cytokines in the tumor microenvironment has been described to promote progression and metastasis. Our objective was to evaluate the prognostic role of genetic polymorphisms and serum levels of IL-6 and IL-8 in a cohort of Mexican pediatric patients with NB. The detection of the SNPs rs1800795 IL-6 and rs4073 and rs2227306 IL-8 was carried out by PCR-RFLP and the levels of cytokines were determined by the ELISA method. We found elevated circulating levels of IL-8 and IL-6 in NB patients compared to the control group. The genotype frequencies of the rs1800795 IL-6 and rs4073 IL-8 variants were different between the patients with NB and the control group. Likewise, the survival analysis showed that the GG genotypes of rs1800795 IL-6 (p = 0.014) and AA genotypes of rs4073 IL-8 (p = 0.002), as well as high levels of IL-6 (p = 0.009) and IL-8 (p = 0.046), were associated with lower overall survival. We confirmed the impact on an adverse prognosis in a multivariate model. This study suggests that the SNPs rs1800795 IL-6 and rs4073 IL-8 and their serum levels could be promising biomarkers of a poor prognosis, associated with overall survival, metastasis, and a high risk in Mexican children with NB.

Abstract
OBJECTIVE To determine the possible associations of polymorphisms in interleukin (IL)-8 (rs4073 T/A), IL-10 (rs1800896 A/G), IL-22 (rs1179251 C/G and rs2227485 C/T), IL-27 (rs17855750 T/G), and transforming growth factor beta 1 (TGFß1) (rs1800469 C/T) with colorectal cancer (CRC) susceptibility in Saudi patients. METHODS The case-control study was carried out between July 2019 and January 2020 in King Khaled University Hospital, Riyadh, Saudi Arabia. A total of 70 patients with CRC and 70 healthy controls were included in the study. Single nucleotide polymorphisms of promoter regions were determined using TaqMan genotyping assays. RESULTS A statistically significant reduction in CRC risk was identified for carriers of the IL-10 (rs1800896 A/G) AG genotype, IL-22 (rs1179251 C/G) G allele, IL-27 (rs17855750 T/G) G allele and TGFß1 (rs1800469 C/T) CT and TT genotype. While IL-10 (rs1800896 A/G) AA genotype and TGFß1 (rs1800469 C/T) CC genotype were significantly associated with increased susceptibility to CRC. No significant associations were identified between the cytokine polymorphisms of IL-8 (rs4073 T/A) and IL-22 (rs2227485 C/T), and CRC risk. Conclusion: Our findings indicate a significant impact of IL-10 (rs1800896 A/G), IL-22 (rs1179251 C/G), IL-27 (rs17855750 T/G) and TGF-ß1 (rs1800469 C/T) polymorphisms on risk of CRC; while the IL-8 (rs4073 T/A) and IL-22 (rs2227485 C/T) and polymorphisms were not associated with CRC risk.

Abstract
Multifunctional pro-inflammatory cytokine CXCL8 is a small peptide of 8-10 kDa in size and it functions as a monomer or dimer. CXCL8 harbors 2 disulfide bonds for its stability. Although production of the CXCL8 protein in a large quantity in both mammalian and bacterial systems has been reported, the processes are complicated and lengthy. Here, we develop a new bacterial expression system for recombinant CXCL8 and simplify the purification system to yield a high amount of protein quickly. The purified CXCL8 protein from our new system develops a crystal structure that is identical to that produced through the mammalian expression system. Thus, we have established a simple and efficient recombinant CXCL8-producing system, which can be easily operated and is suitable to those requiring a large quantity of CXCL8.

Abstract
This study aimed to determine the main single nucleotide polymorphisms (SNPs) that are associated with an increased or decreased risk of glioma development in healthy individuals. We conducted a systematic review of the articles published in English on the PUBMED database between January 2008 and December 2017. Our search resulted in a total of 743 articles; however, only 56 were included in this review. A total of 148 polymorphisms were found, which involved 64 different genes. The polymorphisms that were most associated with an increased risk of glioma development were polymorphic variants rs179782, rs13181, and rs3791679 of the genes XRCC1, ERCC2, and EFEMP1, respectively.

Abstract
Background Several studies have been performed to investigate the associations between interleukin (IL)-8 rs4073 polymorphism and acute pancreatitis (AP), but the results are inconclusive. We conducted this cumulative meta-analysis for a precise estimate of the relationship between IL-8 rs4073 polymorphism and acute pancreatitis. Methods We searched the electronic databases for relevant studies. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to evaluate the strength of the associations. For a better presentation of how the pooled ORs changed as updated evidence accumulated, we used forest plots from a cumulative meta-analysis method. Results Ten studies involving 1646 AP patients and 1816 controls were finally included in this meta-analysis. Cumulative meta-analyses indicated there is a consistent trend toward association after the initial discovery. Under the allelic, dominant, recessive and homozygous models, the pooled ORs were 1.265 (1.147–1.395, p < 0.001), 1.304 (1.127–1.508, p < 0.001), 1.431 (1.203–1.702, p < 0.001), and 1.634 (1.334–2.001, p < 0.001), respectively. Conclusions This meta-analysis demonstrated a suggestive result that people who carried the risk A allele of the IL-8 rs4073 polymorphism may be more sensitive to acute pancreatitis.

Proinflammatory Cytokine Gene Polymorphisms in Bullous Pemphigoid. Front Immunol 2019; 10:636.

Abstract
Bullous pemphigoid (BP) is a rare autoimmune skin blistering disease, characterized by the presence of autoantibodies against hemidesmosomal autoantigens. Cytokine expression is altered in BP patients, and several of these differently expressed cytokines, including IL-1α, IL-1β, IL-8, and TNF-α, contribute to disease pathogenesis. Since genetic polymorphisms in the genes of these cytokines might be implicated in susceptibility to BP disease, we aimed at testing this implication in susceptibility to BP in an Iranian cohort. Blood samples were collected from the subjects and genomic DNA was extracted. To detect the single nucleotide polymorphisms (SNPs), IL-1α (rs1800587), IL-1β (rs1143627, rs16944, rs1143634), IL-8 (rs4073), and TNF-α (rs1799964, rs1800630, rs1799724, and rs361525) genes were genotyped in BP patients and healthy controls as well as IL-8 (rs4073) in pemphigus vulgaris (PV) patients. Quantitative gene expression was evaluated by RT-PCR analysis. A significant difference was observed in the distribution of genotypes or alleles of IL-8 SNP between the BP patients and controls. The A-allele of IL-8 SNP is significantly more prevalent in the control individuals compared to the BP patient. To further validate this observation, we included PV patients as an additional control. Again, the A-allele of IL-8 SNP is significantly more prevalent in the PV compared to the BP patients. While we observed a trend toward significant differences regarding alleles of TNF-α rs1799724 as well as alleles of TNF-α rs1799964, this difference was, however, not evident after correction for multiple analysis. There was no significant difference in all other studied SNPs. In contrast to IL-1α, IL-1β, and TNF-α, IL-8 gene expression levels were significantly higher in the patients than that of controls. The minor allele in IL-8 SNP might play a protective role in susceptibility to BP in Iranian patients. Although higher expression levels of IL-8 gene was found in the patients compared with healthy controls, these levels, however, suggest no association with the examined polymorphism. Moreover, further investigation revealed an elevation in gene expression between wild and polymorphic genotypes of IL-1α rs1800587 and TNF-α rs361525 in the patient group and these SNPs are therefore associated with altering the levels of gene expression.

Abstract
Background Although the associations between common single nucleotide polymorphisms (SNPs) of EFEMP1 gene and glioma risk have been investigated in Chinese population-based case–control studies, investigation results for several SNPs are inconsistent. In addition, the single-center study has a poor statistical power due to finite sample size. Therefore, a meta-analysis was conducted to comprehensively determine the associations. Methods All eligible case–control studies were obtained by searching PubMed, EMBASE, Web of Science, and Chinese National Knowledge Infrastructure. Pooled odds ratio (OR) with 95% confidence interval (CI) was used to assess the strength of the associations in fixed- or random-effects model. Results EFEMP1 rs1346787 polymorphism was significantly associated with glioma risk in Chinese population under all genetic models (GG vs AA, OR =2.22, 95% CI =1.46–3.36; AG vs AA, OR =1.54, 95% CI =1.27–1.87; (GG+AG) vs AA, OR =1.60, 95% CI =1.34–1.93; GG vs (AG+AA), OR =1.86, 95% CI =1.24–2.78; G vs A, OR =1.54, 95% CI =1.32–1.79). However, the significant association of EFEMP1 rs1346786 with glioma risk in Chinese population was observed only under heterozygous model of AG vs AA (OR =1.34, 95% CI =1.10–1.62), dominant model of (GG+AG) vs AA (OR =1.36, 95% CI =1.13–1.63), and allelic model of G vs A (OR =1.28, 95% CI =1.10–1.50). Conclusion Our study demonstrated that EFEMP1 polymorphisms, especially rs1346787 and rs1346786, might predict glioma risk in Chinese population. However, high-quality case–control studies with larger sample sizes are warranted to confirm the above-mentioned findings.

Abstract
Here we report an in-silico approach for identification, characterization and validation of deleterious non-synonymous SNPs (nsSNPs) in the interleukin-8 gene using three steps. In first step, sequence homology-based genetic analysis of a set of 50 coding SNPs associated with 41 rsIDs using SIFT (Sorting Intolerant from Tolerant) and PROVEAN (Protein Variation Effect Analyzer) identified 23 nsSNPs to be putatively damaging/deleterious in at least one of the two tools used. Subsequently, structure-homology based PolyPhen-2 (Polymorphism Phenotyping) analysis predicted 9 of 23 nsSNPs (K4T, E31A, E31K, S41Y, I55N, P59L, P59S, L70P and V88D) to be damaging. According to the conditional hypothesis for the study, only nsSNPs that score damaging/deleterious prediction in both sequence and structural homology-based approach will be considered as 'high-confidence' nsSNPs. In step 2, based on conservation of amino acid residues, stability analysis, structural superimposition, RSMD and docking analysis, the possible structural-functional relationship was ascertained for high-confidence nsSNPs. Finally, in a separate analysis (step 3), the IL-8 deregulation has also appeared to be an important prognostic marker for detection of patients with gastric and lung cancer. This study, for the first time, provided in-depth insights on the effects of amino acid substitutions on IL-8 protein structure, function and disease association.

Abstract
Breast cancer is the leading cause of death of women in worldwide. The real mechanism of breast cancer is still unclear. IL-8 is a member of the chemokine superfamily, which plays an important role in regulating both inflammatory and immune processes. We performed a hospital-based case-control study to estimate the association between IL-8 -251A/T, -353A/T and +781C/T polymorphisms and risk of breast cancer in a Chinese population, and interaction between IL-8 polymorphism and environmental factors. During January 2014 and July 2016, a total of 442 patients with breast cancer and 447 normal control subjects were enrolled into our study. The IL-8 -251A/T, -353A/T and +781C/T polymorphisms were analyzed by the polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP). The TT genotype of IL-8 -251A/T was associated with higher risk of breast cancer as compared with the AA genotype (adjusted OR=1.96, 95% CI=1.26-3.05). Individuals carrying TT genotype of IL-8 -251A/T was correlated with an elevated risk of breast cancer in recessive model, when compared with the AA+AT genotype (adjusted OR=1.91, 95% CI=1.26-2.90). For the IL-8 +781C/T, the TT genotype showed lower association with risk of breast cancer in comparison to the CC genotype (adjusted OR=0.49, 95% CI=0.26-0.91); the TT genotype was also correlated with a decreased risk of breast cancer in recessive model (adjusted OR=0.46, 95% CI=0.25-0.84), as compared with the CC+CT genotype. In conclusion, our study suggests that IL-8 -251A/T and +781C/T could potentially be a biomarker for susceptibility to breast cancer risk.

Tumour Biol 2015; 37:6191-6. [PMID: 26615418 DOI: 10.1007/s13277-015-4435-6] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2015] [Accepted: 11/12/2015] [Indexed: 12/18/2022] Open
Abstract
Interleukin-8 (IL-8) is an angiogenic chemokine that plays a potent role in both development and progression of many human malignancies. However, there are no data about the role of IL-8 polymorphism in development of osteosarcoma. A hospital-based case-control study was conducted among 190 patients with osteosarcoma and 190 healthy controls to investigate the possible association between the IL-8 -251 A/T and +781 C/T polymorphisms, respectively, and the risk of osteosarcoma. Significant differences of genotype distribution were observed between osteosarcoma cases and controls at the IL-8 -251T/A genotypes. Compared with the IL-8 -251T/A homozygote TT, the heterozygous TA genotype was associated with significantly increased risk for osteosarcoma (odds ratio (OR) = 2.16, 95 % confidence interval (CI) = (1.38-4.52), P = 0.021); the AA genotype was associated with increased risk for osteosarcoma (OR = 1.94, 95 % CI = 1.31-3.83, P = 0.018). TA and AA combined variants were associated with increased risk for osteosarcoma compared with the TT genotype (OR = 1.72, 95 % CI = 1.45-4.41, P = 0.023). Moreover, the genotype AA of IL-8 -251T/A carried a higher risk of osteosarcoma metastasis and later Enneking stages, compared with the TT genotype. However, the genotype and allele frequencies of IL-8 +781 C/T polymorphisms in osteosarcoma patients were not significantly different from controls. Our results showed that the IL-8 -251 A/T genotype was associated with increased risk for development and metastasis of osteosarcoma in Chinese Han population.
