Although it was not the main focus of our study, we wanted to see how applicable this gene expression profiling of blood cells was to humans, said Raymond W. Tennant, Ph.D., in the NIEHS Laboratory of Molecular Toxicology, and a co-author on the study.
The NIEHS researchers compared the animal data with data from RNA from blood drawn from individuals who had been admitted to the University of North Carolina emergency room for acetaminophen overdose intoxication. When they compared the toxic blood samples to the samples from normal healthy volunteers they saw a striking difference.
Although there are already some good tools available to emergency room physicians to detect liver injury, additional information concerning the level of exposures and/or the degree of liver injury could significantly help us in treating acetaminophen overdose patients, said Paul Watkins, M.D., Director, General Clinical Research Center at the University of North Carolina, Chapel Hill and co-author on the paper.
