A major goal of the Nuclear Receptor Signaling Atlas (NURSA) is to elucidate the biochemical and physiological roles of nuclear receptors in vivo. Characterizing the tissue expression pattern of individual receptors and their target genes in whole animals under various pharmacological conditions and genotypes is an essential component of this aim. Here we describe a high-throughput quantitative, real-time, reverse-transcription PCR (QPCR) method for the measurement of both the relative level of expression of a particular transcript in a given tissue or cell type, and the relative change in expression of a particular transcript after pharmacologic or genotypic manipulation. This method is provided as a standardized protocol for those in the nuclear receptor field. It is meant to be a simplified, easy to use protocol for the rapid, high-throughput measurement of transcript levels in a large number of samples. A subsequent report will provide validated primer and probe sequence information for the entire mouse and human nuclear receptor superfamily.
