| 1 | -449 C>G polymorphism of NFKB1 gene,coding nuclear factor-kappa-B,is associated with the susceptibility to ulcerative colitis显示文摘AIM:To clarify the association between a polymorphism-449 C>G(rs72696119) in 5'-UTR of NFKB1 with ulcerative colitis(UC).METHODS:The studied population comprised 639 subjects,including patients with UC(UC cases,n = 174) and subjects without UC(controls,n = 465).We employed polymerase chain reaction-single strand conformation polymorphism to detect the gene polymorphism.RESULTS:The rs72696119 G allele frequencies in controls and UC cases were 33.4% and 38.5%,respectively(P = 0.10).Genotype frequency of the GG homozygote in UC cases was significantly higher than that in controls(P = 0.017),and the GG homozygote was significantly associated with susceptibility to UC [odds ratio(OR),1.88;95%CI,1.13-3.14].In male subjects,the GG homozygote was associated with an increased risk for UC(OR,3.10;95%CI,1.47-6.54;P = 0.0053),whereas this association was not found in female subjects.In addition,the GG homozygote was significantly associated with the risk of non-continuous disease(OR,2.06;95%CI,1.12-3.79;P = 0.029),not having total colitis(OR,2.40;95%CI,1.09-3.80,P = 0.040),disease which developed before 20 years of age(OR,2.80;95%CI,1.07-7.32,P = 0.041),no hospitalization(OR,2.28;95%CI,1.29-4.05;P = 0.0090) and with a maximum of 8 or less on the UCDAI score(OR,2.45;95%CI,1.23-4.93;P = 0.022).CONCLUSION:Our results provide evidence that NFKB1 polymorphism rs72696119 was significantly associated with the development of UC.This polymorphism influences the susceptibility to and pathophysiological features of UC. | Ranji Hayashi Tomomitsu Tahara Tsukasa Yamaaki Takashi Saito Kazuhiro Matsunaga Nobuhiko Hayashi Atsushi Fukumura Kazuaki Ozaki Masakatsu Nakamura Hisakazu Shiroeda Mikihiro Tsutsumi Tomoyuki Shibata Tomiyasu Arisawa | 2012 | World Journal of Gastroenterology2012,18,47: | 2 |
