Tumoral gastrin-releasing peptide (GRP) receptors are potential targets for diagnosis and therapy using radiolabeled or cytotoxic GRP analogs. GRP-receptor overexpression has been detected in endocrine-related cancer cells and, more recently, also in the vascular bed of selected tumors. More information on vascular GRP-receptors in cancer is required to asses their potential for vascular target...

cDNA clones to human prepro-gastrin-releasing peptide (prepro-GRP) mRNA detect synthesis of prepro-GRP-related transcripts in 4 of 7 small cell lung cancer (SCLC) cell lines and 1 of 2 metastatic SCLC tumors examined. A correlation is noted between prepro-GRP gene expression and the occurrence of bombesin-related immunoreactivity in SCLC cell lines. Examination of the structure of prepro-GRP tr...

Recent studies have shown that aberrantly expressed gastrin-releasing peptide (GRP) and its receptor (GRP-R) critically regulate tumor cell differentiation in colon cancers developing in humans and mice. This finding suggested that the ability of GRP/GRP-R to promote a well-differentiated phenotype in colon cancer might reflect a re-capitulation of a normal role in regulating intestinal organog...

Gastrin-releasing peptide (GRP) has been suggested as a novel regulatory peptide in the female reproductive tract but the presence of GRP and GRP mRNA in the non-neurogenic tissue of the cervix has not yet been clarified. In the present study, immunohistochemistry and in situ hybridization were used to reveal the distribution of GRP immunoreactivity and expression of GRP mRNA in the bovine cerv...

The mechanism of pipe–soil interaction under frost heaving is complicated due to many factors affecting the system. In order analyze sensitivity various influencing and highlight relationship between pipe’s mechanical characteristics during heaving, a model based on semi-infinite elastic frozen soil foundation developed. Besides, indices characterizing influence their change law are emphaticall...
