Japanese Researchers Identify 25 New Biomarkers for Cyanide Poisoning
A study by Kindai University and Aichi police scientists found 25 compounds that distinguish cyanide-exposed mice with high precision. The work was published in an international toxicology journal in May.
Japan TimesResearchers from Kindai University and the Aichi Prefectural Police Department identified 25 new biomarkers that distinguish cyanide-exposed mice from non-exposed mice with high precision. The study was published in an international toxicology journal in May.
The team, led by Kindai University professor Kei Zaitsu, analyzed metabolic changes in mice after cyanide exposure by measuring a broad range of metabolites.
They also examined 2-aminothiazoline-4-carboxylic acid, or ATCA, a cyanide metabolite long regarded as a promising biomarker. Tests using three types of feed with differing ingredient compositions showed little effect on ATCA production. The finding supports ATCA’s potential usefulness as a forensic indicator.
The researchers plan to validate the 25 biomarkers using human autopsy samples and other specimens. Cyanide is an acutely toxic substance that has been used in murders and terrorist attacks, and blood concentrations decline over time, prompting the search for alternative detection methods based on metabolites.
