| Abstract |
The A Disintegrin And Metalloprotease (ADAM) family of metalloproteases affects a variety of proteins with important roles in development and disease, including growth factors and adhesion molecules. We have analyzed the expression patterns of ADAMs 9, 10, and 17 during pancreas ontogeny. All ADAMs investigated were expressed in the pancreatic anlagen but invariably became restricted to divergent pancreatic compartments. ADAM9 and 17 became restricted to the insulin-producing beta-cells and all islet cells, respectively. During embryogenesis, ADAM10 was detected predominantly in acinar cells, but in the adult, it was localized to the cell surface membrane of both endocrine and exocrine cells. In addition to ADAM9, a potential prognostic factor for ductal cancers, we describe the expression of ADAM10 and ADAM17 in the pancreatic ductal epithelium. Altogether, the dynamic expression profile of the ADAM proteases described here may reflect a functional divergence of these as mediators of pancreas biology. |
