Corticotropin-releasing hormone (CRH) and related peptides (urocortins, sauvagine, urotensin) play a central role in the co-ordination of autonomic, behavioural, cardiovascular, immune and endocrine responses to stressful stimuli. Their actions are mediated through activation of two types of G-protein-coupled receptors encoded by separate genes. In this review we focus on the diverse structural and functional characteristics of the family of CRH-like peptides and their receptors.

Abstract Members of the adhesion family of G protein-coupled receptors (GPCRs) have received attention for their roles in health and disease, including cancer. Over the past decade, several members of the family have been implicated in the pathogenesis of glioblastoma. Here, we discuss the basic biology of adhesion GPCRs and review in detail specific members of the receptor family with known functions in glioblastoma. Finally, we discuss the potential use of adhesion GPCRs as novel treatment targets in neuro-oncology.

Regulation of beta 1-adrenergic receptors is unusual in developing animals. For example, glucocorticoid-and thyroid hormone-responsiveness for several genes is seen in animals treated during fetal life but beta 1-responsiveness is not seen until after birth. In order to investigate this at the transcriptional level, the ovine beta 1 receptor gene was cloned from a sheep genomic library. An approach using high-stringency screening with cDNA probes and oligonucleotides from regions of human and rat genes conserved but unique to the beta 1 receptor but not to other seven transmembrane, G-protein-coupled receptors. Over 800,000 clones were screened from which 40-50 positive clones were identified by each of the probes. There was, however, only a single clone which was recognized by each of the probes. A 5-kb insert was subcloned and shown to contain sequences which hybridized to each of the probes. Using the restriction map of the rat beta 1 receptor, a 1.0-kb Pst1 internal fragment was further subcloned for sequence identification. Confirmation of this fragment as the ovine beta 1 receptor was based on homology of the beta 1 receptor from other species and tissue distribution of mRNA. Nucleotide sequence homology was 93% with the human beta 1 receptor and 84% with rat. Amino acid sequence homology was > 75% and approached 100% in the transmembrane regions. The approach described represents a practical approach to cloning and identification of hormone receptors from the highly homologous members of the seven-transmembrane, G-protein-coupled receptors.

Pth1 Receptor

The parathyroid hormone receptors (nomenclature as agreed by the NC-IUPHAR Subcommittee on Parathyroid Hormone Receptors [47]) are family B G protein-coupled receptors. The parathyroid hormone (PTH)/parathyroid hormone-related peptide (PTHrP) receptor (PTH1 receptor) is activated by precursor-derived peptides: PTH (84 amino acids), and PTHrP (141 amino-acids) and related peptides (PTH-(1-34), PTHrP-(1-36)). The parathyroid hormone 2 receptor (PTH2 receptor) is activated by the precursor-derived peptide TIP39 (39 amino acids). [125I]PTH may be used to label both PTH1 and PTH2 receptors.
