| 8 | Polymorphisms in oxidative pathway related genes and susceptibility to inflammatory bowel disease显示文摘AIM To investigate whether common variants in the oxidative pathway genes influence inflammatory bowel disease(IBD) risk among Moroccan patients. METHODS The distribution of(TAAA)n_rs12720460 and(CCTTT)n_rs3833912 NOS2 A microsatellite repeats, HIF-1 A_rs11549467 and NFKB1-94 ins/delA TTG_rs28362491 was analyzed in 507 subjects grouped in 199 IBD and 308 healthy controls. Genotyping was performed withpolymerase chain reaction-fluorescent method and the TaqMan~? allelic discrimination technology.RESULTS The allele and genotype frequencies of HIF1 A_ rs11549467, NFKB1_rs28362491 and NOS2 A_(TAAA)n did not differ significantly between patients and controls. Analysis of NOS2 A_(CCTTT)n markers evidenced differences between patients and healthy controls. A preferential presence of the(CCTTT)8(P = 0.02; OR = 1.71, 95%CI: 1.07-2.74),(CCTTT)14(P = 0.02; OR = 1.71, 95%CI: 1.06-2.76) alleles in IBD,(CCTTT)8(P = 0.008; OR = 1.95, 95%CI: 1.17-3.23) in CD and(CCTTT)7(P = 0.009; OR = 7.61, 95%CI: 1.25-46.08),(CCTTT)11(P = 0.05; OR = 0.51, 95%CI: 0.25-1.01),(CCTTT)14(P = 0.02; OR = 2.05, 95%CI: 1.07-3.94),(CCTTT)15(P = 0.01; OR = 2.25, 95%CI: 1.16-4.35) repeats in UC patients indicated its possible association with higher disease risk which need to be confirmed in a larger sample size. CONCLUSION Our results suggest that the NOS2 A_(CCTTT)n gene variations may influence IBD susceptibility in the Moroccan population. | Nezha Senhaji Sellama Nadifi Younes Zaid Aurora Serrano Daniel Arturo Leon Rodriguez Nadia Serbati Mehdi Karkouri Wafaa Badre Javier Martín | 2017 | World Journal of Gastroenterology2017，23，47： | 1 |
