Global analysis of G-protein-coupled receptor signaling in human tissues

FEBS Lett. 2003 Aug 28;550(1-3):11-7. doi: 10.1016/s0014-5793(03)00762-2.


The G-protein-coupled receptor (GPCR) family mediates a host of cell-cell communications upon activation by diverse ligands. Numerous GPCRs have been shown to display anatomically selective patterns of gene expression, however, our understanding of the complexity of GPCR signaling within human tissues remains unclear. In an effort to characterize global patterns of GPCR signaling in the human body, microarray analysis was performed on a large panel of tissues to monitor the gene expression levels of the receptors as well as related signaling and regulatory molecules. Analysis of the data revealed complex signaling networks in many tissue types, with tissue-specific patterns of gene expression observed for the majority of the receptors and a number of components and regulators of GPCR signaling.
