Application: Bombesin is a 14-amino-acid neuropeptide originally isolated from amphibian skin and is structurally related to mammalian gastrin-releasing peptide and neuromedin B. It binds with high affinity to the GRP receptor and activates signaling pathways involved in gastrin secretion, gastrointestinal motility, appetite regulation, and cellular proliferation. Bombesin is also recognized as a tumor-associated peptide marker, particularly in small cell lung carcinoma, neuroblastoma, pancreatic cancer, and gastric cancer. This peptide is widely used in cancer biology, gastrointestinal research, receptor signaling studies, tumor marker analysis, and GRP receptor-targeted diagnostic development.
