Nephrin, a gene product of the congenital nephrotic syndrome of the Finnish type (NPHS1), is a 1242-residue putative transmembrane protein of the immunoglobulin family of cell adhesion molecules. The expression of this gene is localized in rat and human glomerular epithelial cells. Here we report the expression of nephrin in various tissues other than the kidneys in mice. The expression of nephrin mRNA in various tissues of mice, including the kidneys, testes, spleen, thymus and brain, were first investigated by the RT-PCR method, and it was shown that a high level of nephrin mRNA could be detected in the testes of mice 1-6 weeks old. In situ hybridization revealed the expression of the nephrin gene in the Sertoli cells. Additionally, immunofluorescent staining studies indicated that nephrin was colocalized with anchoring protein ZO-1 in the mouse testis. From these results, it is inferred that nephrin is an important component of the barrier system in testes.

During development, the expression of PTHrP mRNA is much higher before 2 weeks of age while kidney is developing. In E16 fetal mice, PTHrP mRNA was strongly expressed in the collecting ducts, urothelium of the pelvis, tubles, the glomeruli and immature elements in the cortex of the developing kidney (nephrogenic zone). within 0-day-old-mice, it was dominantly expressed in collecting ducts, the urothelium of the pelvis and nephrogenic zone. These findings suggest that PTHrP plays a role in kidney development as an autocrine/ paracrine factor. en-copyright= kn-copyright= en-aut-name=AyaKunihiko en-aut-sei=Aya en-aut-mei=Kunihiko kn-aut-name=綾邦彦 kn-aut-sei=綾 kn-aut-mei=邦彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部小児科学講座 en-keyword=副甲状腺ホルモン関連ペプチド(PTHrP) kn-keyword=副甲状腺ホルモン関連ペプチド(PTHrP) en-keyword=腎臓 kn-keyword=腎臓 en-keyword=発達 kn-keyword=発達 en-keyword=in situ hybridization kn-keyword=in situ hybridization END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=1997 dt-pub=19970930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=腎臓における副甲状腺ホルモン関連ペプチドの局在の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=綾邦彦 kn-aut-sei=綾 kn-aut-mei=邦彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END
