Gastrin-releasing-peptide(1-27) (GRP) has been implicated in the regulation of satiety and appetite in numerous paradigms. However, the specific site and mode of action of this gut-brain peptide has not been elucidated. The following experiment examined the effects of GRP on taste responses to sucrose in the behaving rat. A brief-exposure, multi-bottle gustometer was used to provide rats with m...

Bombesin (BBS) exerts significant effects on the growth of a mouse colon cancer cell line (MC-26) in vitro. The presence of specific binding sites on MC-26 cells for gastrin-releasing peptide (GRP)/BBS-related peptides was recently reported by us. In the present study, we determined that the transcript size of the mRNA species that codes for GRP receptors is 9 kilobase pairs, which is similar t...

B-type natriuretic peptide (BNP)-natriuretic peptide receptor A (NPRA) and gastrin-releasing peptide (GRP)-GRP receptor (GRPR) systems contribute to spinal processing of itch. However, pharmacological and anatomic evidence of these two spinal ligand-receptor systems are still not clear. The aim of this study was to determine the spinal functions of BNP-NPRA and GRP-GRPR systems for regulating s...

This article examines the impact of Belt and Road Initiative (BRI) on Chinese economy, particularly in certain provinces. After 2008 global financial crisis, economic growth slowed. President Xi Jinping introduced BRI 2013. The initiative’s purpose is to energize strengthen China's progress advance cooperation between countries connected by it. considers BRI's consequences impacts Gross Regiona...

UNLABELLED The 14-amino-acid peptide bombesin (BN) has a high affinity for the gastrin-releasing peptide (GRP) receptor that is expressed by a variety of tumors. Recently, high densities of GRP receptors were identified by in vitro receptor autoradiography in human prostate and breast carcinomas using [(125)I-Tyr(4)]BN as radioligand. Radiometal-labeled diethylenetriaminepentaacetic acid (DTPA)...

Bombesin-like peptides have been implicated as autocrine growth factors influencing the pathogenesis and progression of some human lung carcinoma cells. To determine the pharmacologic and structural properties of the bombesin receptors expressed in human lung carcinoma cells, cDNA clones encoding a human gastrin-releasing peptide receptor (GRP-R) and a pharmacologically distinct neuromedin-B pr...

We identified the Grp gene, encoding gastrin-releasing peptide, as being highly expressed both in the lateral nucleus of the amygdala, the nucleus where associations for Pavlovian learned fear are formed, and in the regions that convey fearful auditory information to the lateral nucleus. Moreover, we found that GRP receptor (GRPR) is expressed in GABAergic interneurons of the lateral nucleus. G...
