Interaction of Polymorphisms of Resistin Gene Promoter -420C/G, Glutathione Peroxidase -1 Gene Pro198Leu and Cigarette Smoking in Nonalcoholic Fatty Liver Disease / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Many studies have suggested that cigarette smoking and polymorphisms of resistin and glutathione peroxidase-1 (GPx-1) genes are closely correlated with the pathogenesis of nonalcoholic fatty liver disease (NAFLD). However, few reports have investigated these associations with respect to NAFLD susceptibility. We, therefore, examined the distribution of polymorphisms in GPx-1 and resistin genes in NAFLD patients and healthy controls and analyzed the relationship between these polymorphisms and smoking status.</p><p><b>METHODS</b>Nine hundred NAFLD patients and 900 healthy controls were selected, and the genetic polymorphisms of resistin gene promoter-420C/G and GPx-1 gene Pro198Leu were analyzed by polymorphism-polymerase chain reaction (PCR) in DNA extracted from peripheral blood leukocytes. Interactions between the two mutants and the gene-environment interaction with cigarette smoking were also analyzed.</p><p><b>RESULTS</b>Genotype frequencies of -420C/G (GG) and Pro198Leu (LL) were significantly higher in NAFLD cases (49.56% and 50.11%, respectively) compared with healthy controls (23.67% and 24.22%, respectively) (P = 0.0069; P = 0.0072). Moreover, the risk of NAFLD with -420C/G (GG) was significantly higher than in controls (odds ratio [OR] =3.1685, 95% confidence interval (CI) =1.9366-5.2073). Individuals carrying Pro198Leu (LL) had a high risk of NAFLD (OR = 3.1424, 95% CI = 1.7951-5.2367). Combined analysis of the polymorphisms showed that the -420C/G (GG)/Pro198Leu (LL) genotype was significantly more common in the NAFLD group than in the control group (39.44% vs. 12.78%, respectively, P = 0.0054), while individuals with -420C/G (GG)/Pro198Leu (LL) had a high risk of NAFLD (OR = 5.0357, 95% CI = 3.1852-7.8106). Moreover, the cigarette smoking rate in the NAFLD group was significantly higher than in the control group (OR = 1.8990, P = 0.0083 in the smoking index (SI) ≤400 subgroup; OR = 5.0937, P = 0.0051 in the SI >400 subgroup), and statistical analysis suggested a positive interaction between cigarette smoking and -420C/G (GG) (γ = 5.6018 in the SI ≤400 subgroup; γ = 4.4770 in the SI >400 subgroup) and Pro198Leu (LL) (γ = 5.7715 in the SI ≤400 subgroup; γ = 4.5985 in the SI >400 subgroup) in increasing the risk of NAFLD.</p><p><b>CONCLUSION</b>NAFLD risk factors include -420C/G (GG), Pro198Leu (LL) and cigarette smoking, and these three factors have a significant additive effect on NAFLD risk.</p>

<p><b>OBJECTIVE</b>To investigate the interaction of the polymorphisms of cyclooxygenase-2-1195G/A (COX-2-1195G/A) and manganese superoxide dismutase 9Ala/Val (MnSOD9Ala/Val) genes and the high-fat diets and its potential correlation with ulcerative colitis (UC).</p><p><b>METHODS</b>The genetic polymorphisms of COX-2-1195G/A and MnSOD9Ala/Val were analyzed by polymorphism-polymerase chain reaction (PCR) in peripheral blood leukocytes obtained from 750 UC patients (UC group) and 750 healthy subjects (control group).</p><p><b>RESULTS</b>The frequencies of COX-2-1195G/A(A/A) and MnSOD9Ala/Val(V/V) were 49.07% and 50.13% in UC group and 21.20% and 22.40% in control group, respectively (P<0.01). The risk of UC significantly increased in subjects with COX-2-1195G/A(A/A) genotype (OR=3.5808,95%CI=1.8062-5.3478) and in those with MnSOD9Ala/Val(V/V) genotype(OR=3.4828,95%CI=1.9137-5.5496). Pooled analysis of the polymorphisms showed that distribution frequency of COX-2-1195G/A(A/A)/MnSOD9Ala/Val (V/V) was 40.67% in UC group and 8.40% in control group (P<0.01). Subjects with COX-2-1195G/A(A/A)/MnSOD9Ala/Val(V/V) had a significantly higher risk of UC (OR=7.5655,95% CI=4.1849-11.2037). The rate of high-fat diets was significantly higher in the UC group than in the control group(49.73 vs.20.13%,P<0.01),and statistic analysis suggested an interaction between high-fat diet and COX-2-1195G/A(A/A)(Γ=11.81821)and MnSOD9Ala/Val (V/V)(Γ=9.0107), which increase risk of UC.</p><p><b>CONCLUSIONS</b>COX-2-1195G/A(A/A),MnSOD9Ala/Val (V/V), and high-fat diet are the risk factors of UC. The interaction between the genetic polymorphisms of COX-2-1195G/A and MnSOD9Ala/Val and the high-fat diet increases the risk of UC.</p>
