Characterization of bombesin/gastrin-releasing peptide receptors in membranes of MKN45 human gastric cancer.

G Halmos et al.

Cancer letters, 85(1), 111-118 (1994-09-30)

Binding of the radiolabeled bombesin analog [125I-Tyr4]bombesin to crude cell membranes of MKN45 human gastric cancer grown in nude mice was investigated in vitro. Scatchard analyses of multipoint binding data, performed by complete displacement method demonstrated the presence of two

Localization of iodine-125-mIP-Des-Met14-bombesin (7-13)NH2 in ovarian carcinoma induced to express the gastrin releasing peptide receptor by adenoviral vector-mediated gene transfer.

B E Rogers et al.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 38(8), 1221-1229 (1997-08-01)

The gastrin releasing peptide receptor (GRPr) has a high affinity for the 14 amino acid bombesin peptide. For this analysis, [125I]-Tyr4-bombesin was compared with [125I]-mIP-bombesin (a seven amino acid bombesin analog) for in vitro binding and internalization into tumor cells

Expression of receptors for gut peptides in human pancreatic adenocarcinoma and tumour-free pancreas.

C Tang et al.

British journal of cancer, 75(10), 1467-1473 (1997-01-01)

Gut hormones that modulate the growth of normal pancreas may also modulate the growth of cancers originating from pancreas. This study visualized and compared the receptors for cholecystokinin (CCK), bombesin (BBS), secretin and vasoactive intestinal peptide (VIP) in tumour-free tissue

High-affinity binding sites for gastrin-releasing peptide on human colorectal cancer tissue but not uninvolved mucosa.

S R Preston et al.

British journal of cancer, 71(5), 1087-1089 (1995-05-01)

Human colorectal cancer tissue and matched uninvolved mucosa from 21 patients were examined by radioligand displacement for the presence of binding sites for bombesin-like peptides. Five cancers, but no uninvolved mucosa, expressed high-affinity, low-capacity bombesin binding sites (Kd = 6.53

BW2258U89: a GRP receptor antagonist which inhibits small cell lung cancer growth.

T W Moody et al.

Life sciences, 56(7), 521-529 (1995-01-01)

The ability of reduced peptide bond analogues of gastrin releasing peptide (GRP) to antagonize small cell lung cancer (SCLC) GRP receptors was investigated. BW462U89, BW1023U90, BW2123U89 and BW2258U89 inhibited binding of (125I-Tyr4) BN to NCI-H345 cells with IC50 values of
