MicroRNAs as Translational Biomarkers for Drug-Induced Liver Injury
NCTR scientists published a review article in Biomarkers in Medicine (2013, 7: 307-315)3, which discusses the potential advantages and challenges of using microRNAs (miRNAs) as new translational biomarkers of drug-induced liver injury (DILI). miRNAs are small single-stranded RNA molecules that can alter the expression of various genes. Although miRNAs appear to be more sensitive and organ-specific than conventional DILI biomarkers, their true value remains to be fully assessed due to a lack of standard quantification methods and confirmatory studies.

An NCTR scientist gave a presentation at the 2nd International Conference and Exhibition on Metabolomics and Systems Biology held in Northbrook, Illinois, on April 8-10, 2013. The talk focused on the use of metabolomics to evaluate preclinical biomarkers of hepatotoxicity; with special emphasis on common blood metabolite profiles between preclinical animals treated with drugs that cause observable liver injury and human patients with idiosyncratic drug-induced liver injury. The identification of common metabolite profiles could be useful in the development of improved clinical trial designs and improved detection of idiosyncratic DILI risk.
