Regulatory cytokine gene polymorphisms and risk of colorectal carcinoma.
2006
It is well established that cancer arises in chronically inflamed tissue, and this is particularly notable in the gastrointestinal tract. Classic examples include Helicobacter pylori-associated gastric cancer, hepatocellular carcinoma, and inflammatory bowel disease-associated colorectal cancer. Growing evidence suggests that these associations might be not casual findings. Focusing on individual cytokines has generated evidence that anti-inflammatory cytokine interleukin (IL)-10 and transforming growth factor-beta1 (TGF-beta1) may have a complex role in gastrointestinal carcinogenesis. As an example, IL-10-deficient mice develop severe atrophic gastritis and a chronic enterocolitis, develo…
Search for genetic factors associated with susceptibility to multiple sclerosis.
2006
Multiple sclerosis (MS) is a cell-mediated autoimmune disease characterized by type-1 cytokine production. Environmental and individual genetic background might influence this response particularly in cytokine gene polymorphisms. We evaluated whether polymorphisms of interleukin (IL)-10, IL-12, and tumor necrosis factor (TNF)-alpha genes, which might play a role in MS pathogenesis, are associated with MS susceptibility. Genotype frequencies for all the analyzed polymorphisms were not differently distributed between cases and controls. It is reasonable to suppose that the cytokine single-nucleotide polymorphisms (SNPs) studied must be considered against a larger genetic background involving …

Genetic Determined Downregulation of Both Type 1 and Type 2 Cytokine Pathways Might Be Protective against Pancreatic Cancer
2009
Many cytokine polymorphisms have been studied for associations with susceptibility to breast, gastric, liver, lung, prostate, and ovarian cancer without conclusive results. The cytokine network, indeed, is characterized by complex interactions, and the final biological effect of a single genetic variation depends on the balance among different molecular signals. As is well known, Th1/Th2 cytokine unbalanced production might predispose to different pathologies, cancer included. In general, a prolonged type 1 inflammatory response might allow that cells accumulating enough "genetic hits" are promoted to neoplastic transformation. On the other hand, IL-13-producing cells through the IL-13/IL-4…

Frequency of polymorphisms of signal peptide of TGF-beta1 and -1082G/A SNP at the promoter region of Il-10 gene in patients with carotid stenosis
2006
The role of inflammation in atherosclerosis is well recognized. We have evaluated the allele frequencies of the +869T/C and +915G/C polymorphisms (SNPs) at the TGF-beta1 gene and -1082G/A SNP at IL-10 promoter sequence, two well-known immunosuppressive and anti-inflammatory cytokines, in patients with carotid stenosis. Our data suggest a lack of association between these SNPs and the susceptibility to atherosclerosis although other reports have demonstrated this association. These results may be due to the pleiotropic effects of the cytokines and/or differences in haplotype combination that should be investigated to elucidate the role of TGF-beta1 and IL-10 polymorphisms in atherosclerosis.

Role of environmental and genetic factor interaction in age-related disease development: the gastric cancer paradigm.
2008
The association of Helicobacter pylori (Hp) infection with gastric cancer is well known and might be considered a paradigmatic example of the role that interaction among environmental factors and individual background might play in inducing age-associated disease. To evaluate the role of interaction of Hp infection with genetic background, gastric cancer and chronic gastritis patients as well as random selected controls were typed for five inflammation-related polymorphisms of IL-1 and IL-10 cytokine genes. No association among IL-10 or IL-1 variants with an increased risk of gastric cancer was found, whereas an Hp-independent association of IL-1beta -511T positive genotypes to an increased…

Cytochrome P450 2E1 variable number tandem repeat polymorphisms and health risks: A genotype-phenotype study in cancers associated with drinking and/…
2012
Cytochrome P450 2E1 (CYP2E1) is one of the main enzymes involved in the oxidation of ethanol and in the transformation of a number of potentially dangerous compounds. It has various polymorphic sites, one of which is a variable number tandem repeat (VNTR) polymorphism previously described in the 5'-flanking region. The aim of this study was to investigate the genotype-phenotype association between CYP2E1 VNTR polymorphisms and risky health habits in healthy subjects and to analyze the associations between these polymorphisms with drinking- and/or smoking-related cancers. We analyzed 166 healthy subjects by genotyping for the CYP2E1 VNTR polymorphism associated with drinking and/or smoking h…

IL-6 -174G/C polymorphism and IL-6 serum levels in patients with liver cirrhosis and hepatocellular carcinoma.
2011
Recently, a link between high levels of circulating IL-6 and hepatocellular carcinoma (HCC) has been proposed. In addition, single nucleotide polymorphisms (SNPs) in the promoter region of the IL-6 gene have been reported to be related to several inflammatory-related conditions, including cancer. The purpose of this article is: (1) to evaluate the frequencies of SNPs in the IL-6 promoter region at position -174 and IL-6 serum levels in a group of patients with HCC and underlying liver cirrhosis (LC), and compare them with a group of LC patients without HCC; (2) to determine whether a possible correlation exists between the allelic variations, IL-6 serum levels, and the risk of developing HC…
Association Between Single Nucleotide Polymorphisms in the Cyclooxygenase-2, Tumor Necrosis Factor-α, and Vascular Endothelial Growth Factor-A Genes,…
2011
Cyclooxygenase-2 (COX-2), vascular endothelial growth factor-A (VEGF-A), and tumor necrosis factor-α (TNF-α) are mediators of inflammation and angiogenesis; all of them are produced in liver cirrhosis (LC) and in hepatocellular carcinoma (HCC). It was proposed that there is an association between single nucleotide polymorphisms (SNPs) and HCC. These allelic variants influence the transcriptional activity of these genes, and therefore the proteins levels. The VEGF-A pathway is a potential therapeutic target in HCC, and several antiangiogenic agents have entered clinical trials in HCC. We evaluated the frequency of SNPs of COX-2, TNF-α, and VEGF-A genes in patients with HCC versus LC patients…

Cytokine Gene Polymorphisms and Breast Cancer Susceptibility
2006
Human breast cancer (BC) is characterized by a considerable clinical heterogeneity. Steroid hormone receptor expression and growth factor receptor expression have been considered suitable diagnostic and prognostic markers, whereas mutations of oncosuppressor and gatekeeper genes have been found associated with an increased risk for this malignancy. To evaluate the role that polymorphisms of genes involved in the regulation of inflammatory response might play in BC susceptibility, we investigated associations between cytokine functionally relevant polymorphisms in 84 BC patients compared to 110 age- and sex-matched controls. TNF-alpha (-308G/A), TGF-beta1 (+869C/T), IL-10 (-1117G/A; -854C/T;…

Analysis of Candidate Genes in Celiac Disease: A Tool to Identify Life-Threatening Associated Genes?
2006
The authors have recently reported that celiac patients show a proinflammatory cytokine genetic profile characterized by the contemporaneous presence of both the tumour necrosis factor-alpha-308A and the interferon-gamma +874T allele-positive genotypes. The same alleles are considered risk factors for aging associated disease, whereas an anti-inflammatory cytokine genotype profile might be associated with an extended life expectancy. This paper reports data on the 1249-1250InsACAA/Non-Ins transforming growth factor (TGF)-beta2, a multifunctional anti-inflammatory cytokine, polymorphism distribution in 88 celiac disease (CD) patients, 99 age- and sex-matched controls, and 2895-year-old healt…
