Up-Regulation of microRNA-210 is Associated with Spermatogenesis by Targeting IGF2 in Male Infertility

چکیده
BACKGROUND MicroRNAs (miRNAs) play pivotal roles in spermatogenesis. MicroRNA-210 (miR-210) expression was up-regulated in the testes of sterile men with non-obstructive azoospermia (NOA). However, the underlying mechanisms of miR-210 involved in the spermatogenesis in patients with NOA are unknown. MATERIAL AND METHODS Expression of miR-210 and insulin-like growth factor II (IGF2) in the testes of NOA cases (only including maturation arrest and hypospermatogenesis) were detected in this study. We carried out in vitro experiments to determine if IGF2 was directly targeted by miR-210 in NT2 cells. RESULTS Compared with obstructive azoospermia (OA) as normal control, our results suggest that miR-210 was significantly up-regulated in testis of patients with NOA (P<0.05), and IGF2 was down-regulated, but without a significant difference. The results also indicated that IGF2 was directly targeted by miR-210 in NT2 cells. CONCLUSIONS The results showed that miR-210 was involved in spermatogenesis by targeting IGF2 in male infertility.

Significance of microRNA targeted estrogen receptor in male fertility
Objective(s): Estrogen receptor-alpha (ERα) mediates estrogen action in regulation of different levels of the hypothalamic-pituitary-testis axis. It has a key role in spermatogenesis. Estrogen receptor alpha knock-out (ER koα) male mice were infertile and severe impairment in spermatogenesis and seminiferous tubules was observed. Recently, it has been reported that microRNA (miRNA) mir-100 and ...
متن کاملThe functional and predictive roles of miR-210 in cryptorchidism
Idiopathic diseases of the reproductive system are important factors leading to male infertility. Many studies have shown that microRNAs (miRNAs) regulate the expression of multiple genes that play a significant role in spermatogenesis and development. We previously showed that microRNA-210 (miR-210) is one of the markedly upregulated microRNAs in the testes of sterile males with maturation arr...
