title: Targeting gastrin releasing peptide receptors: New options for the therapy and diagnosis of cancer.
abstract: Gastrin-releasing peptide (GRP), the mammalian bombesin (BN), appears to be involved in the growth of several neoplasms. BN/GRP receptors (BN/GRP-Rs) are expressed in a variety of cancer cells and have limited distribution in normal human tissue. Thus inhibition of BN/GRP-Rs represents an attractive target for pharmacological treatment of some human malignancies. This review will focus on intracellular signaling pathways which have been characterized to mediate BN/GRP-dependent receptor biological effects as well as on various approaches to target BN/GRP-Rs for therapeutic and diagnostic interventions in human malignancies.
