German Team Taps RNA-seq to Find Candidate Biomarkers for Detecting Steroid Abuse in Livestock

By Molika Ashford – In Sequence

German researchers have shown that RNA-sequencing can be a potent tool to identify gene expression signatures that can distinguish livestock animals illegally treated with anabolic steroids.

The team, from three German institutions, published a report in Analytical Chemistry this month evaluating RNA-seq as a tool for finding gene expression changes associated with physiological effects of growth-promoting agents.

Using RNA-seq on just a few samples from a breed of heifer, and then profiling additional samples for the most promising candidate biomarkers using RT-qPCR, the researchers were able to precisely distinguish animals treated with anabolic steroids from controls, they reported.
