This study examined the expression of receptors of the bombesin (BBS) family in human gastric-cancer cell lines. Of 5 cell lines screened, only one, St42. demonstrated specific binding sites for '251-Ty&BBS, which have been further characterized. This binding was saturable, and temperature-and time-

## Abstract Nude mice bearing xenografts of the gastrinβresponsive human gastric carcinoma MKN45 cell line were treated for 4 to 5 weeks with bombesin/gastrinβreleasingβpeptide(GRP) antagonist (RCβ3095), somatostatin analogues RCβ160 and SMS 201β995, or the combination of RCβ3095 and RCβ160. Tumor
BACKGROUND. Bombesin-like peptides can function as autocrine or paracrine growth factors and stimulate the growth of some cancer cells, including human prostate cancer. Three bombesin receptor subtypes, termed gastrin-releasing peptide receptor (GRPR), neuromedin B receptor (NMBR), and bombesin rece
