Abstract
The purpose of this study was to determine the effect of the gastrin receptor antagonist, CR2093, on basal and gastrin-stimulated growth of primary human colorectal adenocarcinomas and to relate this to gastrin receptor expression. Tumour cells, derived from surgical specimens by enzymatic disaggregation, were grown on matrices of type I collagen and irradiated fibroblasts. Gastrin receptor expression was measured by using a mouse monoclonal antibody directed against the gastrin receptor and an avidin-biotin immunocytochemical method. Increased growth in the presence of gastrin-17 (used at physiological concentrations and as assessed by [3H] thymidine uptake) was shown in 16/34 (47%) tumours. CR2093 significantly reversed this stimulated growth (P
