Testicular gene expression of Anti-Müllerian hormone, Androgen receptor and Inhibin alpha subunit in porcine cryptorchidism
Cryptorchidism, one of the common congenital abnormalities in boars, results ina boar taint in the carcass and economic loss. However, knowledge of gene expression of hormones controlling the testicular descent process, such as anti-Müllerian hormone (AMH), androgen receptor (AR) and inhibin alpha subunit (INHA), in porcine testicular cryptorchidismis still limited. The present study aimed to investigate the gene expression profiles of AMH, ARand INHAin undescended testes (UDT) and descended testes (DT) in unilateral cryptorchid pigs of suckling (12 weeks of age), nursery (6weeks of age) and growing-finishing pigs (1520 weeksof age) and in normal testes (NT) at 12 weeks of age, using quantitative real-time reverse transcription PCR (qRT-PCR). A significant decrease in expression of AMHand ARgenes in the UDT group was observed compared with the DT group at 1520 weeks. Within each group, the highest expression of AMHwas observed at 6 weeks of age, whereas the lowest expression was shown at 1520 weeks compared with other ages. For the expression of AR, the lowest expression was revealed only in the UDT group at 1520 weeks compared with other ages. Prominent expression of ARandINHAwas observed in the DT group at 20 weeks. In conclusion, this study unveiled the decreased expression of AMHand ARgenesin UDT compared with DT in growing-finishing pigs. Markedly increased expression of ARand INHAwas observed in DT when pigs reached puberty.
