Abstract
INTRODUCTION Guillain-Barré syndrome (GBS) is a common autoimmune disease in the peripheral nervous system. This study aimed to elucidate the role of IL-27 gene polymorphisms in elderly people with GBS. METHODS A total of 395 healthy subjects and 422 GBS patients with an average age of 63 years old were included in this study. Peripheral blood samples were collected. The 2 single-nucleotide polymorphisms (SNPs) of IL-27, namely, rs153109 and rs785575, of GBS patients were analyzed using the PCR method and compared with those of the healthy controls. The correlations of IL-27 SNPs with disease severity, disease outcome, level of anti-GM1 antibodies, and Campylobacter jejuni infection were assessed. Serum levels of IL-27 of healthy subjects and GBS patients were analyzed using enzyme-linked immunosorbent assay. RESULTS No significant differences in the frequencies of rs785575 SNPs between GBS and healthy subjects were observed. In analyzing rs153109 SNPs, the G allele was found to be more prevalent in the GBS patients (p = 0.012). More alleles show GG genotype in GBS patients (p = 0.023). The -964A>G allele has a higher prevalence in severely affected and anti-GM1-Ab-positive GBS patients. GBS patients with the rs153109 SNP showed a poor clinical outcome than those without rs153109 SNP (p = 0.012). GBS patients showed higher serum IL-27 levels than healthy subjects (p < 0.001). The levels of IL-27 were also higher in GBS patients with genotypes of AG and GG, and those with GG genotypes showed the highest IL-27 levels. CONCLUSION The rs153109 SNP is more prevalent in GBS patients with the GG and G allele and is associated with severer GBS, poorer clinical outcomes, and higher IL-27 levels.

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
Objectives: This study investigated the relationship between single-nucleotide polymorphisms (SNPs) in cytokine genes and the susceptibility to Squamous Intraepithelial Lesions (SIL), cervical cancer and HPV infection through a systematic review with meta-analysis. To verify the effect of SNPs, we also analyzed the transcription factor binding affinity using bioinformatics tools.Methods: Seven electronic databases (MEDLINE, Scielo, BIREME, PubMed, Scopus, Web of Science and Science Direct) were searched for case-control studies.Results: A total of 35 relevant case-control studies were meta-analyzed, including 7 cytokine genes and 15 SNPs. SNPs in IL-17A (rs2275913, rs3748067); IL-17 F (rs763780); IL-12A (rs568408); IL-12B (rs3212227); TNFA (rs1800629, rs361525); IL-1B (rs16944); IL-6 (rs1800795); IL-10 (rs1800896) genes were associated with increased risk for cervical cancer. No association was observed between meta-analyzed polymorphisms and SIL. Additional bioinformatics analysis suggested a possible transcriptional regulation pathway of the TNFA and IL-10 genes through the MZF1 (TNFA -308 G > A and IL-10 - 1082A>G) and ZNF263 (TNFA -238 G > A) transcription factors binding.Conclusion: Overall, 10 SNPs in cytokine genes were associated with increased risk for cervical cancer. Therefore, in our meta-analysis, these SNPs demonstrated to be potential biomarkers for predicting or identifying cases of high risk for SIL and cervical cancer.

Abstract
BACKGROUND: Advanced lung cancer is indicated with rapid disease development. Interleukin 27 (IL-27) is regarded as a cytokine with anti-tumour activities. AIM: Since, the impact of type of lung cancer on the level of IL-27 in patient’s serum has not yet been investigated; current study evaluated the clinical stages according to American Joint Committee on Cancer (AJCC) criteria, Tumor-Node-Metastasis (TNM) stage and the lung cancer spread (localized or widespread) and it’s correlation with serum IL-27. MATERIAL AND METHODS: Thirty patients with confirmed histopathological lung cancer and 30 cancer-free healthy individuals as the control group were included in the current study. Patients group were assigned to either small cell lung cancer group (SCLC) or non-small cell lung cancer (NSCLC) according to the clinical features and the results of lung biopsy specimens. Level of IL-27 was quantified with enzyme-linked immunosorbent assay (ELISA) test in serum samples. RESULTS: A significant increase in serum IL-27 level was noticed in individuals with lung cancer in comparison with the control group. The level of serum IL-27 in the NSCL squamous carcinoma (NSCLC-Sc) type was significantly greater than in the NSCLC adenocarcinoma (NSCLC-Ad) type, and in both groups, this variable was more than the control group. The serum IL-27 content level was greater in stage III versus stage IV. CONCLUSION: The current research confirmed the existence of the anti-tumour components in patients with NSCLC. IL-27 can be utilised in diagnosis and screening in early stages of lung cancer along with the management of patients. Different levels of IL-27 in different types of lung cancers in the current study can lead to design more comprehensive studies in the future.

Mol Genet Genomic Med 2018; 7:e00516. [PMID: 30460760 PMCID: PMC6382450 DOI: 10.1002/mgg3.516] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2018] [Revised: 10/10/2018] [Accepted: 10/25/2018] [Indexed: 01/30/2023] Open
Abstract
Background Disordered inflammation and immune response is an acknowledged risk factor for cervical cancer development. Interleukin‐1 receptor type 2 (IL1R2) is a decoy receptor for IL‐1 cytokines and involved in host inflammatory and immune progression which could lead to the lesion and neoplasia of cervix. In this study, we aimed to evaluate the relationships between IL1R2 polymorphisms and cervical cancer risk in Uygur females from China. Methods In this case–control study, genotypes of six selected variants (rs11674595, rs4851527, rs719250, rs3218896, rs3218977, and rs2072472) distributed in IL1R2 were detected among 247 cervical cancer patients and 286 healthy controls with the usage of an Agena MassARRY method. Furthermore, Genetic models and haplotype analyses were conducted to estimate the associations of IL1R2 polymorphisms with cervical cancer risk. Results After statistical analyses, rs719250 (odd ratio [OR] = 1.436, 95% confidence interval [95% CI] = 1.079–1.911, p = 0.013) and rs3218896 (OR = 1.552, 95% CI = 1.080–2.229, p = 0.017) showed obvious evidence in correlation to cervical cancer susceptibility owing to the surviving significant differences between cases and controls in allele model. Genetic model analyses also revealed significant associations of rs719250 and rs3218896 with cervical cancer risk in the codominant model, the dominant model and the log‐additive model even after adjustment for age (p < 0.05). Moreover, haplotype “T/A” of rs11674595/rs4851527 (adjusted OR = 0.73, 95% CI = 0.54–0.98, p = 0.037) and “T/C” of rs719250/rs3218896 (adjusted OR = 1.61, 95% CI = 1.10–2.36, p = 0.015) exhibited protective and risky effects for Uygur individuals on cervical cancer development, respectively. Conclusion Our data first shed the new light on the associations of IL1R2 polymorphisms with cervical cancer susceptibility among Uygur females. These results are supposed to facilitate the tumorigenesis genetic research among Chinese minorities.

The interleukin-27 -964A>G polymorphism enhances sepsis-induced inflammatory responses and confers susceptibility to the development of sepsis. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2018; 22:248. [PMID: 30268141 PMCID: PMC6164187 DOI: 10.1186/s13054-018-2180-0] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/25/2018] [Accepted: 09/05/2018] [Indexed: 02/03/2023]
Abstract
Background Previous studies have identified critical roles of IL-27 in the pathological mechanisms of sepsis, and blockade of IL-27 may be a promising alternative therapy for sepsis. The purpose of this study was to evaluate the clinical relevance of IL-27 genetic polymorphisms in sepsis and to further characterize their effect on IL-27 expression and inflammatory processes following sepsis. Methods A total of 885 septic patients and 1101 healthy controls were enrolled and genotyped for IL-27 genetic variants (rs153109/−964A > G and rs17855750/2905 T > G). Quantitative real-time PCR and enzyme-linked immunosorbent assays were performed to detect IL-27 expression and cytokine production. The effect of the rs153109 polymorphism on IL-27 promoter activity was evaluated using a luciferase reporter assay, and THP-1 cell apoptosis was calculated using an annexin V apoptosis assay. Results No significant differences in the genotype/allele frequencies were observed between patients with sepsis and healthy controls, suggesting that these two IL-27 polymorphisms may not influence susceptibility to sepsis. The -964AA genotype was overrepresented in patients with severe sepsis/septic shock relative to patients with the sepsis subtype, and the A allele was significantly associated with 28-mortality in sepsis. Patients carrying the -964AA genotype exhibited significantly higher expression levels of IL-27 than the GA/GG genotype carriers. The results of an in vitro (lipopolysaccharide (LPS))-stimulated experiment showed that this sepsis-associated high-risk AA genotype significantly increased IL-27 levels and enhanced TNF-α and IL-1β production in the peripheral blood mononuclear cells (PBMCs) upon exposure to LPS in vitro. Furthermore, luciferase reporter assays indicated that the high-risk -964A allele resulted in increased promoter activities compared to the non-risk allele in THP-1 and 293 T cells. Additionally, IL-27 treatment significantly enhanced TNF-α and IL-6 secretion and apoptosis of THP-1 cells upon LPS stimulation. Conclusions These results provided evidence that the IL-27 -964A > G polymorphism functionally enhanced IL-27 expression and promoted sepsis-induced inflammatory responses, which ultimately resulted in promoting the progression of sepsis and poor prognosis.

Association of IL-27 rs153109 and rs17855750 Polymorphisms with Risk and Response to Therapy in Acute Lymphoblastic Leukemia. Pathol Oncol Res 2017; 24:653-662. [PMID: 28828696 DOI: 10.1007/s12253-017-0295-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2017] [Accepted: 08/14/2017] [Indexed: 12/15/2022]
Abstract
Interleukin (IL)-27 is a cytokine with important anti-cancer activity. This study has evaluated the effects of IL-27 rs153109 and rs17855750 single nucleotide polymorphisms (SNPs) on risk of acute lymphoblastic leukemia (ALL) development, as well as their impact on prognosis and patient survival. A total of 200 patients and 210 healthy subjects were genotyped by polymerase chain reaction-restriction fragment length polymorphism. We observed a higher frequency of rs153109 AG and rs17855750 TG genotypes and allele G in patients compared to controls (p < 0.001). Combined G variant genotypes (AG + GG and TG + GG) also conferred significantly greater risk of ALL. There was a significant correlation between the genotypes of both SNPs with event-free survival (EFS). Patients with GG genotypes of both SNPs and those of rs153109 AG and rs17855750 TG had a shorter EFS than patients with rs153109 AA and rs17855750 TT genotypes (p ≤ 0.035). Combined G variant genotypes for both SNPs showed poorer response to therapy in all patients (p < 0.027) as well as B-ALL (rs153109, p < 0.001) and T-ALL (rs153109, p = 0.048) patients. In multivariate analysis, rs153109 combined G variant genotype was associated with shorter EFS (relative risk = 9.7, p = 0.026). Among those who relapsed, 87.1% had the rs153109 AG genotype and 77.4% had the rs17855750 TG genotype (p < 0.01). Patients had higher IL-27 serum levels compared to controls, but this did not differ between genotypes. In conclusion, the association of IL-27 rs153109 and rs17855750 polymorphisms with risk of ALL development and their impact on EFS suggested an important role for this cytokine in biology and response to ALL therapy.
