Expression data for participants in iWITH study at screening visit, primary endpoint (yr2)/For-cause biopsy visit, 5year visit

A longitudinal study using data collected at the time of liver biopsy, the final eligibility assessment for participation in iWITH (NCT01638559), an immunosuppression withdrawal trial. Microarrays were used to understand the gene expression profile differences between IS withdrawal outcomes (Tolerant and Non-tolerant) RNA samples (n=222) were extracted from cryopreserved liver tissue samples using TRIzol and hybrid-ized onto Affymetrix Human Genome U219 96-array plates.
