Bombesin acetate salt hydrate has been used in immunohistochemical methods and food intake measurements.
Biochem/physiol Actions
Tetradecapeptide originally isolated from the skin of the frog Bombina bombina. Bombesin acts at specific brain nuclei to inhibit food intake. It also increases blood glucose levels.
Bombesin/gastrin releasing peptide (BN/GRP) serves as an autocrine growth factor in small cell lung cancer (SCLC). Overexpression of gastrin releasing peptide receptor (GRP-R) is associated with neuroblastoma tumor aggressiveness. GRP-R modulates the important enzymes, that participates in glucose metabolism. Bombesin, a pulmonary growth factor helps to satisfy the conditions for autocrine stimulation.
General description
Gastrin releasing peptide receptor (GRP-R) belongs to the G protein-coupled receptors (GPCR) family. The gene for the gastrin?releasing peptide receptor is located on the short arm of human X chromosome.
