Abstract

It is hypothesized that hyperuricemia in males is caused by androgen-induced urate reabsorptive transport system in the kidney. The expression of urate transporter 1 (Urat1), sodium-coupled monocarboxylate transporter 1 (Smct1) and glucose transporter 9 (Glut9) were investigated in orchiectomized mice with or without testosterone replacement. Testosterone enhanced mRNA and protein levels of Smct1 while those of Glut9 were attenuated. Although the mRNA level of Urat1 was enhanced by testosterone, the corresponding levels of Urat1 protein remained unaffected. Thus, the induction of Smct1 by testosterone is a candidate mechanism underlying hyperuricemia in males.
