Updated FTP location. The combination analyses of transcriptomics, proteomics, phosphoproteomics, and metabolomics in rat liver after repeated oral doses of PXR agonist, PCN, for 7 days were conducted to understand the roles for PXR on non-genotoxic signaling and energy homeostasis. mRNA and proteins in homogenate supernatant, membrane, and cytosolic fractions prepared from the liver were analyzed.
