General description

GRP (gastrin releasing peptide) is the mammalian homolog of bombesin (BBS) and functions as a mitogen for multiple cancers, such as neuroblastoma. It is a ligand for GRPR (GRP receptor) and is expressed in a subtype of peptidergic dorsal root ganglion neurons.

Application

GRP (gastrin releasing peptide) has been used for absorption/neutralization of anti-GRP antibody prior to the tyramide signal amplification (TSA) procedure.

Biochem/physiol Actions

GRP (gastrin releasing peptide) functions as an autocrine growth factor for nueroblastoma. It facilitates cell survival in PI3K/AKT (phosphatidylinositol-3-kinase/ v-Akt murine thymoma viral oncogene)-mediated manner and cell proliferation and angiogenesis in neuroblastoma. This peptide is involved in the release of gastrin and the control of gastric acid secretion and motor function. In patients with atopic dermatitis, the serum levels of this peptide are linked with pruritus.

Linkage

Mammalian equivalent of bombesin that is found in the central nervous system and gastrointestinal tract. It inhibits food intake. It is produced by and is mitogenic for several tumor cell lines.
