In vivo transcriptomic responses to thioacetamide exposure in rat liver, kidney, and heart tissue. In vivo transcriptomic responses to thioacetamide exposure in rat liver, kidney, and heart tissue

In this study we tested the ability to predict organ injury from transcriptomics data in Sprague-Dawley rats at early time points after exposure to thioacetmide (8 and 24 hours). We selected thioacetamide, an organosulfur compound extensively used in animal studies as a hepatotoxin and carcinogen for its ability to cause acute liver damage. Overall design: We treated 30 Sprague-Dawley rats with saline solution (control), 25 mg/kg (low dose), and 100 mg/kg (high dose) to produce different degrees of injury. RNA samples for gene expression analysis were collected from the liver, kidney, and heart at 8 and 24 hours. Number of repicates were five.
