- Abstract
- The expression of claudin-1 and -11, tight junctions (TJs) proteins was examined in immature and adult pheasant (Phasianus colchicus) testes. Claudin-1 and -11 cDNA were highly similar to those of human, mice, and chicken. Claudin-1 mRNA and protein (21 kDa) levels in immature testes were higher than those of adult testis. In immature testes until 6 weeks of age, Claudin-1 was found at contacts between adjacent Sertoli cells and between Sertoli cells and germ cells. In adult testis, Claudin-1 was found in early spermatocytes migrating the blood testis barrier (BTB). Blood vessels were positive for claudin-1. Claudin-11 mRNA and protein (21 kDa) increased during adulthood development of testis. In immature testis, Claudin-11 was found in apicolateral contacts between adjacent Sertoli cells, indicating its involvement in cell adhesion in immature testis. In adult testis, strong wavy Claudin-11 immunoreactivity was parallel to basal lamina at the basal part of seminiferous epithelium, indicating that Claudin-11 at the inter-Sertoli TJs may act as a structural element of the BTB. Weak Claudin-1 and -11 immunoreactivity at contacts between Sertoli cells to elongating/elongated spermatids, meiotic germ cells, and basal lamina suggests that they also participate in the cell cell and cell extracellular matrix adhesion in pheasant testis. Testosterone increased claudin-11 mRNA in testis organ culture and Sertoli cell primary culture, suggesting positive regulation of claudin-11 gene by androgen in Sertoli cells of pheasant testis. This is the first report on the claudins expression at BTB in avian testis. (C) 2011 Elsevier Inc. All rights reserved.
