Abstract
Host genetic factors could play a primary role in determining the risk for cirrhosis development in chronic hepatitis C virus (HCV)-infected patients. We designed this work to study the effect of single-nucleotide polymorphism (SNP) in Toll-like receptor 3 (TLR3) and interferon regulatory factor (IRF) on the risk of HCV-related cirrhosis. This study enrolled 139 Egyptian HCV-infected patients. They were divided into patients with cirrhotic (56) and noncirrhotic (83) liver. Genotyping of rs3775291 F459F (+1234C/T) and rs3775290 L412F (+1377C/T) in TLR3 and IRF3 rs2304204 (-925A/G) was performed by restriction fragment length polymorphism-polymerase chain reaction. Although there is no significant difference in genotype and allele distribution of +1377C/T of TLR3 gene between cirrhotic and noncirrhotic subjects, CC (odds ratio [OR] = 1.572, 95% confidence interval [CI]: 0.781-3.164); TT (OR = 1.463, 95% CI: 0.351-6.104) genotypes might be considered as risk factors for liver cirrhosis. On the contrary, the analysis revealed that only one genotype (CC) and one allele (C) were detected in +1234C/T SNP, with the total disappearance of CT/TT genotypes and T allele in all subjects. On the contrary, lower frequency has been found for the AG genotype of the IRF3 (-925A/G) gene in cirrhotic patients compared with noncirrhotic ones, indicating that AG is a protective genotype (OR = 0.509, 95% CI: 0.256-1.012). Our data stressed the association of AG genotype SNP in IRF3 (-925A/G) in protection against the worth outcome of HCV infection.

Abstract
Interferon Regulatory Factor-3 (IRF-3) is one of the key players in the inflammatory response mediated by the innate immune system. Although many studies have implicated a role for IRF-3 in the pathogenesis of inflammatory airway diseases, information about the possible association of IRF-3 genetic variants with asthma is scarce. We aimed to investigate the potential effects of IRF-3 polymorphisms in childhood asthma and asthma-related phenotypes. IRF-3 polymorphisms were first determined by sequencing 25 asthmatic and 25 healthy children. For further analysis, 609 asthmatic children and 191 healthy controls were screened for the genetic variants, such as rs2304204, rs2304205, rs320440, rs34739574, and rs7251. In addition, the relationship between these polymorphisms and asthma-related phenotypic features, including forced expiratory volume in one second values, eosinophil counts, and IgE levels was determined. rs7251 was associated with asthma in the codominant (P = 0.049) and G dominant (P = 0.025) model, however this significance was lost after False Discovery Rate analysis. Other investigated single nucleotide polymorphisms (SNPs) showed no significant association with asthma or asthma-related phenotypes. In conclusion, the seven SNPs of IRF-3 gene are not associated with asthma or asthma-related phenotypes in Turkish asthmatic children.
