Ötzi the Iceman: Researchers validate the stability of genetic markers

(Saarland University) Biomarkers are biological attributes that can give doctors or researchers clues about the health status or illnesses of a patient. Scientists are placing great hope in a new type of biomarker, so-called microRNAs. These short ribonucleic acid molecules are notable for their very high level of stability. Researchers at Saarland University, the University of Luxembourg and the Eurac Research center in Bozen have now established that such microRNAs can remain stable even after 5,300 years.
