Abstract

The testis and epididymis are important organs of the male reproductive system; the functionis to produce, mature, transport, and store sperm. It is important to understand the localization and expressionof specific proteins based for the studies of its physiological processes. In this study, we investigated theexpression and distribution of galectin-3, one of beta-galactoside-binding proteins, in the testis andepididymis of mouse using western blot and imunohistochemistry. Western blot analysis revealed that theexpression of galectin-3, 29 kDa protein, was low in the testis. In the epididymis, high expression wasdetected in the body and tail part, but moderate expression in the head part. By immunohistochemicalanalysis, we found that positive localization of galectin-3 was detected in some myoid cells and Leydigin the epithelium of epididymis, especially in the epithelium of both body and tail of epididymis. Collectively,these results suggest that galectin-3 is constitutively expressed in the testis and epididymis of mouse withvarying intensity, and the role of galectin-3 in the male reproductive organ may be involved in the specificfunction of its structures.
