IL28B Genotype Is Associated With Differential Expression of Intrahepatic Interferon-Stimulated Genes in Patients With Chronic Hepatitis C
Open accessAbstract
Genetic variation in the IL28B (interleukin 28B; interferon lambda 3) region has been associated with sustained virological response (SVR) rates in patients with chronic hepati-tis C (CHC) who were treated with peginterferon- a and ribavirin. We hypothesized that IL28B polymorphism is associated with intrahepatic expression of interferon-stimulated genes (ISGs), known to influence treatment outcome. IL28B genotyping (rs12979860) and whole-genome RNA expression were performed using liver biopsies from 61 North American patients with CHC. After correction for multiple testing (false discovery rate < 0.10), 164 transcripts were found to be differentially expressed by IL28B -type. The inter-feron signaling pathway was the most enriched canonical pathway differentially expressed by IL28B -type ( P < 10 25 ), with most genes showing higher expression in livers of individ-uals carrying the poor-response IL28B -type. In 25 patients for which treatment response data were available, IL28B -type was associated with SVR ( P 5 0.0054). ISG expression was also associated with SVR; however, this was not independent of IL28B -type. Analysis of miR-122 expression in liver biopsies showed reduced miR-122 levels associated with poorer treatment outcome, independently of IL28B -type. No association was observed between IL28B -type and levels of liver IL28B or IL28A messenger RNA expression. IL28B protein sequence variants associated with rs12979860 were therefore investigated in vitro : no differences in ISG induction or inhibition of HCV replication were observed in Huh7.5 cells. Conclusion: The good response IL28B variant was strongly associated with lower level ISG expression. The results suggest that IL28B genotype may explain the relationship between hepatic ISG expression and HCV treatment outcome, and this is independent of miR-122 expression. IL28B -type was not associated with intrahepatic IL28B messenger RNA expression in vivo . Further investigation of the precise molecular mechanism(s) by which IL28B genetic variation influences HCV outcomes is warranted. (HEPATOLOGY 2010;52:1888-1896)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
