Abstract

β-catenin, E-cadherin and N-cadherin are adhesion molecules that play important roles in organogenesis, tissue homeostasis, renal epithelial integrity and polarity. The present study demonstrated their immunolocalization in adult and neonate rat kidney. Membranous or cytoplasmic expression of β-catenin, E-cadherin and N-cadherin were seen in adult and developing renal tubular epithelial cells. Particularly, in adult kidney, E-cadherin and β-catenin were intensively expressed in distal renal tubules, whereas N-cadherin was expressed in proximal renal tubules. In neonate rat kidney on 1 and 4 days old, developing renal tubular epithelial cells were mainly reacted with E-cadherin and very weakly expressed N-cadherin; β-catenin was expressed in developing renal tubules and mesenchymal blastemal cells. Interestingly, β-catenin-positive renal tubular epithelial cells simultaneously expressed E-cadherin in the kidney of adult and developing rats. Collectively, the adhesion molecules were differentially distributed in the renal tubules of adult rats and β-catenin and E-cadherin are predominant adhesion molecules in developing kidney. The present findings would provide the basic information of evaluating renal tubular toxicity using rats, in addition to renal genesis, in terms of adhesion molecules.
