Abstract:

The objective of the study was to identify whether the combination of FSH and 17-beta-estradiol regulated the mRNA expression of Cyclin D1 and Cyclin E1 in the cultured immature boar Sertoli cells. Cultured immature boar Sertoli cells were treated with the combination of 17-beta-estradiol (10-9 mol·L-1) and FSH (50 ng·mL-1) and added a variety of different signaling pathway inhibitors. And Real-time PCR was applied to detect the mRNA expression of Cyclin D1 and Cyclin E1. Compared to FSH (50 ng·mL-1) or 17-beta-estradiol (10-9 mol·L-1) alone, the combination of FSH and 17-beta-estradiol had no significant effect on the mRNA expression of Cyclin D1 mRNA and Cyclin E1(P>0.05). In addition, Rp-cAMP (cAMP inhibitor), Verapamil (L-type Ca2+ ionic channel inhibitor) or U0126 (ERK1/2 inhibitor) alone had no significant effect on the mRNA expression of Cyclin D1 and Cyclin E1 in comparison to the control group (no FSH or17-beta-estradiol) (P>0.05). However, three inhibitors could reduce the mRNA expression of Cyclin D1 and Cyclin E1 in a dose-dependent way (P<0.05, for all) when compared to the combined FSH (50 ng·mL-1) and 17-beta-estradiol (10-9 mol·L-1). cAMP, Ca2+ and ERK1/2 were involved in the effect of the combination of FSH and 17-beta-estradiol regulating the mRNA expression of Cyclin D1 and Cyclin E1.
