Bombesin receptors in distinct tissue compartments of human pancreatic diseases.

Lab. Invest. 80 , 1807-1817, (2000)

Overexpression of receptors for regulatory peptides in various human diseases is reportedly of clinical interest. Among these peptides, bombesin and gastrin-releasing peptide (GRP) have been shown to play a physiological and pathophysiological role in pancrea...

Modulation of bombesin-induced phosphatidylinositol hydrolysis in a small-cell lung-cancer cell line.

Biochem. J. 255 , 403-410, (1988)

Bombesin is an amphibian tetradecapeptide whose mammalian homologue, gastrin-releasing peptide (GRP), is produced by many small-cell lung-cancer (SCLC) cells, and which can function in an autocrine growth-promoting manner in SCLC. Studies reported here show t...

Investigation of molecular structure of bombesin and its modified analogues nonadsorbed and adsorbed on electrochemically roughened silver surface.

Biopolymers 89 , 506-521, (2008)

This work describes the molecular structure of bombesin (BN) and its analogs on the basis of the absorption infrared and Raman results described below. In these analogues is replaced one ([D-Phe12]BN, [Tyr4]BN, and [Lys3]BN) or two ([Tyr4,D-Phe12]BN, [D-Phe12...

Mechanism of [Tyr4]bombesin-induced desensitization in dispersed acini from guinea pig pancreas.

Identification of the bombesin receptor on murine and human cells by cross-linking experiments.

J. Biol. Chem. 262(23) , 11215-20, (1987)

The bombesin receptor present on the surface of murine and human cells was identified using 125I-labeled gastrin-releasing peptide as a probe, the cross-linking agent disuccinimidyl suberate, and sodium dodecyl sulfate gels. A clone of NIH-3T3 cells which pos...

High affinity receptors for bombesin/GRP-like peptides on human small cell lung cancer.

Life Sci. 37(2) , 105-13, (1985)

The binding of a radiolabeled bombesin analogue to human small cell lung cancer (SCLC) cell lines was investigated. (125I-Tyr4)bombesin bound with high affinity (Kd = 0.5 nM) to a single class of sites (2,000/cell) using SCLC line NCI-H446. Binding was revers...

Bombesin-related peptides induce calcium mobilization in a subset of human small cell lung cancer cell lines.

J. Biol. Chem. 262(34) , 16456-60, (1987)

To examine the biochemical basis for growth factor-induced responses in human lung cancer cells, we used the quin2 technique to study the effect of the amphibian peptide bombesin and its congeners including mammalian gastrin-releasing peptide (GRP) on the int...

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

Br. J. Cancer 71(5) , 1087-9, (1995)

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...

ATP induces two cholecystokinin binding affinity states in permeabilized rat pancreatic acini.

Am. J. Physiol. 263(1 Pt 1) , G44-51, (1992)

The influence of adenine and guanine nucleotides on cholecystokinin (CCK) receptor binding was examined in streptolysin O-permeabilized rat pancreatic acini. Specific binding of tracer to intact acini was 12.1 +/- 0.4% per milligram protein, while permeabiliz...

Bombesin receptors in a human duodenal tumor cell line: binding properties and function.

Cancer Res. 54(3) , 818-24, (1994)

The bombesin family of peptides elicit numerous biological responses in the gut, including stimulation of cell proliferation, and have been implicated as growth factors in a variety of gastrointestinal tumors. Even though these peptides and their receptors ar...
