Methods A hospital-based case-control study was conducted in 381 cases with HBV-related HCC, 340 HBsAg carriers and 359 non-tumor controls. Genotypes of-572 site of IL-6 gene and-819, -592 sites of IL-10 gene were determined by real-time polymorphism chain reaction. Unconditional logistic regression was used to estimate the odds ratios(ORs)and 95 confidence intervals(C/s). Results For the G/C alleles of -572 loci on IL-6 gene, there were significant differences between the three groups(P<0.05). Compared with CC genotype, GG genotype increased the risk of HBV infection (OR=2.171,95% Ch 1.068-4.415), but did not seem to be associated with HCC. For the alleles of-819 and -592 site of IL-10 gene, there were significant differences between the three groups(P<0.05). Compared with CC genotype, TT genotype increased the risks of both HCC(OR=2.791,95%CI:1.326-5.874), and HCC in HBsAg carriers(0R=3.522,95%CI: 1.707-7.266). When compared with CC genotype on -592 site, the AA genotype reduced the risk of both HCC(OR=0.389, 95% CI:0.173-0.875), and HCC in HBsAg carriers(OR=0.336, 95% CI: 0.154-0.734). Conclusion The SNPs in -572 site of IL-6 gone might be associated with the risk of HBV infection. The SNPs in -819 site of IL-10 gene increased the risk of HCC, but -592 site of IL-10 gene decreased the risk of HCC. 相似文献

BackgroundPrevious studies about the association of the interleukin-10 (IL-10) polymorphisms with the progression of liver fibrosis or cirrhosis susceptibility in chronic hepatitis B/C (CHB/C) disease were inconsistent. The aim of this meta-analysis was to derive a more precise estimation of the association.MethodsWe searched Medline, PubMed, EMBASE and Web of Science electronic databases using the following key words: liver fibrosis/cirrhosis, IL10, and polymorphism. Statistical analyses were performed by STATA11.0 software, with odds ratios (ORs) and their 95% confidence intervals (CIs).Results12 independent studies in relation to IL10-1082A/G, -819C/T and -592C/A polymorphisms were included in our study, which consisted of 197 moderate/severe liver fibrosis cases and 426 mild fibrosis controls as well as 536 liver cirrhosis cases and 881 non-cirrhosis controls. The results indicated that a significantly decreased risk of moderate/severe fibrosis was associated with the GCC haplotype (IL10-1082G, -819C and -592C) in the overall CHB/C patients (OR: 0.547, 95% CI: 0.317–0.946, P = 0.031). We did not detect any significant association between these polymorphisms and liver cirrhosis susceptibility in the total population or a subgroup of Asians. However, subgroup analyses by different aetiologies showed that the -819T heterozygotes (TC) were associated with a significantly increased risk of HCV-related liver cirrhosis in the Japanese population (OR: 1.254, 95% CI: 1.033–1.522, P = 0.022).ConclusionsThe putative high IL-10 production haplotype GCC is more likely to be associated with less severe liver fibrosis in CHB/C patients. Additionally, the IL10-819T allele may be a susceptible factor for HCV-related liver cirrhosis in the Japanese population. 相似文献

Background
Pleiotropic cytokine interleukin-10 (IL-10) has been suggested as modifying risk for atherosclerosis. Promoter region genetic polymorphism of IL-10 gene is known to be associated with the level of IL-10 production. Through these effects, they might be involved with the ischemic stroke (IS). Our aim was to assess the nature of the functional polymorphisms in IL-10 promoter and any links with IS in Chinese Han population.Methods
The IL-10 -1082 G>A, -819 C>T and -592 C>A functional polymorphisms were determined by TaqMan SNP Genotyping assays in 1296 subjects (648 IS patients diagnosed by CTs or/and magnetic resonance imaging (MRI) and 648 normal healthy controls from Chinese Han Population). Multivariate logistic regression analysis was used to show the association between the IL-10 genotypes and the IS events.Results
We found that the CC genotype of -819 C>T was more common in controls than IS subjects (P<0.05, corrected for multiple testing) in the Han population. CC carriage may be associated with the decreased risk of IS in the Han ethnic group (OR 0.65, 95% CI 0.43-0.97). In addition, the CC genotype in -592 C>A and GG genotype in -1082 G>A are all extremely low in Chinese Han cases and controls.Conclusions
The G allele frequency at the -1082 promoter region of IL-10 was rare in Chinese Han population which are diffierent from American/European populations.. IL-10 -819 C>T may be an independent protective factor for IS in the Chinese Han population.14.
Silicosis is a fibrotic lung disease produced by the inhalation and deposition of silica dust. The association between silicosis and pulmonary tuberculosis (PTB) has been well established. Cytokines participate in the development and progression of silicosis and PTB. Functional polymorphisms in cytokine genes have been identified that alter cytokine production. The aims of the current investigation were to determine whether functional polymorphisms in the tumor necrosis factor-alpha (TNF-alpha) gene at position -308; in the transforming growth factor-beta 1 (TGF-beta1) gene at positions -509, +869 (codon 10), and +915 (codon 25); in the interleukin-10 (IL-10) gene at position -1,082, -819 and -592; and in the intron 1 of the interferon-gamma (IFN-gamma) gene at position +874 are associated with silicosis and PTB. We conducted a case-control study with 183 silicosis patients and 111 silica-exposed miners, and a 1:2 matched case-control study of 61 PTB cases and 122 PTB-free miners. Genotype analysis was performed on genomic DNA, using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. There was complete linkage disequilibrium (LD) between the -819C and -592C alleles of the IL-10 gene. The genotype frequencies were similar between cases and control subjects for all investigated cytokine polymorphisms (p>0.05). We did not find an association between the different genotypes and severity of silicosis. We assume that these genetic variants do not play a dominant role in silicosis and PTB in our Chinese population. 相似文献

Cytokine gene polymorphisms affect vaccine responses and gender-specific effects are known for many phenotypes. Therefore, this study investigated gender-specific effects of cytokine gene polymorphisms on vaccine responses. In 263 2-year-old subjects selected for parental history of atopy, boys with IL-4 C-589T and IL-4Ralpha I50V genotypes associated with atopy had increased Diptheria Toxoid (DiphTox) and Tetanus Toxoid (TetTox) responses compared with the remaining alleles (IL-4 C-589T: DipTox p=0.01, TetTox p=0.04; IL-4Ralpha.I50V: DipTox p=0.04, TetTox p=0.08). Contrastingly, girls with IL-10 -592C genotypes associated with atopy had lower levels of DiphTox (p=0.03) and TetTox (p=0.02) responses compared with the remaining allele. Additionally, interaction effects were found for IL-4 C-589T (p=0.01) and IL-4Ralpha I50V (p=0.04) polymorphisms. In conclusion, these findings support the interaction of primary genetic and modifying factors on vaccine responses and the importance of atopic genetics to these responses. 相似文献

目的进一步确定基因多态性是否为子宫内膜异位症(EMs)患者白细胞介素-10(IL-10)蛋白水平改变的原因之一。方法应用扩增阻滞突变系统-聚合酶链反应(ARMS-PCR)结合DNA测序,以及聚合酶链反应-限制性片段长度(PCR-RFLP)多态性分析方法,检测EMs组和对照组IL-10-1082G/A、-819T/C和-592A/C的基因多态性。ELISA法测定血清和腹腔液中IL-10水平。结果 EMs组和对照组均发现3种单倍型GCC、ACC、ATA,6种单倍型组合,其中以ATA/ATA、ACC/ATA和ACC/ACC占多数。对照组仅-1082位点的多态性与血清、腹腔液IL-10水平相关(P0.01)。EMs组-1082(GG或AG型)、-819(CC或TC型)和-592(CC或AC型)均与腹腔液IL-10水平升高相关(P0.05),其中Ⅰ~Ⅱ期EMs患者仅-1082位点与腹腔液IL-10水平相关(P0.01),Ⅲ~Ⅳ期EMs患者-1082、-819和-592位点的基因型均与腹腔液IL-10水平相关(P0.05)。EMs组-1082、-819、-592基因型与血清IL-10水平无相关性(P0.05)。结论Ⅰ~Ⅱ期EMs影响IL-10表达的遗传学机制主要位于-1082位点,但在Ⅲ~Ⅳ期EMs患者中,腹腔局部因素如某些活性因子等除可作用于-1082位点外,可能还可通过作用于-819和-592位点共同调控IL-10水平,但EMs患者血清IL-10水平与其基因多态无相关性,可能与血清IL-10表达受多种机制调控有关。 相似文献
