Engineered Insulin Secretion from Neuroendocrine Cells Isolated From Human Thyroid.
Decatur, United States. In World J Surg, 19 Mar 2014
Gastrin-releasing peptide (GRP) in conditioned medium and cell lysates was determined by reverse transcription (RT)-PCR, ELISA, and immunohistochemistry. RESULTS: Isolation yielded an average of 2.2 × 10(6) cells/g thyroid tissue, which stained for calcitonin/calcitonin gene-related protein, expressed genes consistent with NE origins, and secreted GRP.
Gastrin-releasing peptide receptor expression in lung cancer.
Porto Alegre, Brazil. In Arch Pathol Lab Med, Jan 2014
CONTEXT: Gastrin-releasing peptide receptors (GRPRs) activate mitogen-activated protein kinase signaling pathway primarily through epidermal growth factor receptor activation and are under investigation as a molecular target because they are overexpressed in several solid tumors.
Luciferase assay to screen tumour-specific promoters in lung cancer.
Quanzhou, China. In Asian Pac J Cancer Prev, 2012
The activity and specificity of seven promoters, comprising CEACAM5 (carcinoembryonic antigen, CEA), GRP (Gastrin-Releasing Peptide), KRT19 (cytokeratin 19, KRT), SFTPB (surfactant protein B, SP-B), SERPINB3 (Squamous Cell Carcinoma Antigen, SCCA), SELP (Selectin P, Granule Membrane Protein 140 kDa, Antigen CD62, GMP) and DKK1 (Dickkopf-1) promoters were compared in lung cancer cells to obtain cancer-specific examples with strong activity.
Autoantibody to the gastrin receptor in pernicious anemia.
In N Engl J Med, 1985
We examined serum IgG fractions from 20 patients with pernicious anemia and 25 control subjects for their capacity to inhibit binding of [125I]15-leu human gastrin-17 to parietal-cell-enriched gastric mucosal cells.
