Research Abstract

We investigated liver biopsy samples and bile samples in clinical liver transplant, applying molecular biological techniques. We found that biomarkers which were associated with acute cellular rejection after liver transplant in the two different OMICS levels ; DNA microarray and proteomic analyses. We then established the non-invasive method for diagnosing acute cellular rejection in liver transplant recipients.
