Zusammenfassung:RNA sequencing (RNA‐seq) is a powerful tool for the evaluation and quantification of transcriptomes and expression patterns in animals, tissues, or pathological conditions. The purpose of this study was to determine the physiologic expression of cytochrome P450 (CYP) mRNA transcripts in whole blood, kidney, duodenum, liver, and lung in healthy, adult male (n = 4) and female (n = 4) beagles via RNA‐seq. mRNA expression was above background (transcripts per million) for 45 canine CYPs, with liver, duodenum, and lung expressing a high number of xenobiotic metabolizing CYPs, while prominent endogenous metabolizing CYP expression was present in blood and kidney. The relative expression pattern of CYP2A13, 2B11, 2C21, 2D15, 2E1, 3A12, and 27A1 in liver, lung, and duodenum was verified through qPCR. This is the first global profiling of physiologic CYP mRNA expression in multiple canine tissues, providing a platform for further studies characterizing canine CYPs and changes in gene expression in disease states.
