The gastrin-releasing peptide receptor (GRPR) is a therapeutic target in colon cancer. Here we show that the GRPR antagonist RC-3095 (10 , 10 , 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.
