Abstract:The gastrin-releasing peptide receptor (GRPR) is a therapeutic target in colon cancer. Here we show that the GRPR antagonist RC-3095 (10-3, 10-6, or 1 μM) decreases nerve growth factor (NGF) secretion measured by enzymelinked immunosorbent assay (ELISA) in HT-29 human colon carcinoma cells. The results suggest that decreased secretion of neurotrophins might be a novel mechanism by which GRPR antagonists exert their antiproliferative effects in cancer cells.

- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
