Abstract:

Background: Cisplatin is a chemotherapeutic drug used to treat testicular cancer that induces testicular toxicity. This study aimed to investigate the possible role of androgens, androgen receptor, and organic cation transporter 2 (OCT2) in the protective effects of curcumin on cisplatininduced testicular toxicity.

Methods: Thirty male Wistar rats were divided into five groups: 1- control (normal saline, 0.5 ml ip, daily for 10 consecutive days); 2- cisplatin (10 mg/kg ip, single dose at the first day); 3- cisplatin + curcumin (10 mg/kg ip, dissolved in 5% DMSO, daily for 10 consecutive days); 4- cisplatin + vehicle (DMSO 5%, 0.3 ml ip); and 5- curcumin (10 mg/kg ip). At the end of the study, a blood sample was obtained for testosterone measurement. The left testis was kept at -80 to measure androgen receptor (AR) and type 2 organic cation transporter (OCT2) gene expression and the right testis were kept in 10% formalin for histological analysis.

Results: Cisplatin significantly decreased serum testosterone, declined testis AR gene expression, and increased OCT2 gene expression in testis (p<0.01). Curcumin treatment significantly prevented these alterations in testosterone and gene expressions (p<0.01). Moreover, curcumin significantly reversed the cisplatin-induced kidney tissue injury and increased spermatid and spermatozoa.

Conclusion: It is concluded that the ameliorative effect of curcumin in cisplatin-induced reproductive disorders was due to the modulation of testosterone and androgen receptors.

Keywords: Cisplatin, androgen receptors, organic cation transporter, curcumin, testis, OCT2 gene.
