Abstract
Background
Interleukin (IL)-23 is involved in the pathogenesis of ulcerative colitis (UC). A genome-wide significant association between IL23R p.G149R (rs76418789) and UC was previously identified in Japan and Korea. This case-control study aims to examine this association within the Japanese population.
Methods
The study included 384 cases diagnosed with UC within the past 4 years and 661 control subjects. Adjustment was made for sex, age, and smoking.
Results
The frequency of the AA genotype of rs76418789 was 0.0 % in cases and 0.5 % in control subjects. In comparison to study subjects with the GG genotype of rs76418789, those with the GA or AA genotype had a significantly reduced risk of UC, with an adjusted odds ratio of 0.67 (95 % confidence interval: 0.44–0.999). A significant multiplicative interaction was observed between rs76418789 and having ever smoked influencing UC (p for interaction = 0.03). A significant positive association was found between having ever smoked and UC in individuals with at least one A allele, while no such positive relationship was observed in those with the GG genotype.
Conclusion
IL23R SNP rs76418789 showed a significant association with UC. This study provides new evidence regarding the interaction between rs76418789 and smoking in relation to UC.
期刊介绍:
The journal Cytokine has an open access mirror journal Cytokine: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
* Devoted exclusively to the study of the molecular biology, genetics, biochemistry, immunology, genome-wide association studies, pathobiology, diagnostic and clinical applications of all known interleukins, hematopoietic factors, growth factors, cytotoxins, interferons, new cytokines, and chemokines, Cytokine provides comprehensive coverage of cytokines and their mechanisms of actions, 12 times a year by publishing original high quality refereed scientific papers from prominent investigators in both the academic and industrial sectors.
We will publish 3 major types of manuscripts:
1) Original manuscripts describing research results.
2) Basic and clinical reviews describing cytokine actions and regulation.
3) Short commentaries/perspectives on recently published aspects of cytokines, pathogenesis and clinical results.
