Abstract: Abstract:Zinc (Zn) concentration in the digestive tract of common carp is always >10 times higher than most animal tissues. In a previous paper, it was reported that this high Zn came from a 43 kDa Zn-binding membrane protein. In this present study it was further found that in the digestive tract of common carp, Zn content was closely associated with the amounts of extracellular macromolecules. The higher the Zn content, the more there is of collagen and glycosaminoglycans. An indirect immunoperoxidase staining method using antibody against the 43 kDa Zn-binding protein, or the fibroblast marker (Thy 1.1 protein) was applied to the sections of digestive tract of fish. It was found that the Zn-binding protein in the digestive tract of common carp is mainly located in the connective tissue of its lamina propria and submucosal layer. Connective tissue cells, probably fibroblasts, hold the 43 kDa Zn-binding protein. In the common carp Zn might be bound to the external side of the fibroblast. The present finding may have a significant meaning on extending the studies of Zn in biology to the field of Zn with extracellular matrix.
