MicroRNAs have emerged as promising biomarkers of organ damage including injury of the liver. In this study the new generation of high-throughput sequencing technology was applied to detect circulating  miRNAs in serum from patients with accidental acetaminophen overdose and identified a set of 33 known miRNAs and 3 novel miRNA-like small RNAs that are functionally associated with liver-specific biological processes and relevant to acetaminophen toxic mechanisms. The study suggests a profile of circulating miRNAs in human serum that might provide additional biomarker candidates for drug-induced liver injury and possibly adds mechanistic information relevant to liver injury.

The liver associated miRNAs miR-122 and miR-192 were detected in serum from acetaminophen-overdosed patients. The graph represents serum levels, based on normalized sequencing reads, of the liver-associated miRNA hsa-miR-122 (A) and hsa-miR-192 (B) in control and acetaminophen-overdosed samples.
