Abstract:
G protein-coupled receptors (GPCRs) mediate effects of extracellular signaling molecules in all the body's cells. These receptors are encoded by scarce mRNAs; therefore, detecting their transcripts with conventional microarrays is difficult. We present a method based on multiplex PCR and array detection of amplicons to assay GPCR gene expression with as little as 1 mug of total RNA, and using it, we profiled three human bone marrow stromal cell (BMSC) lines.

GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
