The levels of INHβB, FSHβB, LHβB, GnRHR and β-glycan were quantified by real-time PCR and western-blotting among pshRNAi-2, pshRNAi-negative and PBS groups, respectively. A: The mRNA levels of INHβB, FSHβB, LHβB, GnRHR and β-glycan were examined by q-PCR. Compared with pshRNA-negative and PBS groups, the mRNA levels of INHβB, FSHβB, LHβB and GnRHR were up-regulated [P>0.05] in APCs transfected with pshRNAi-2. However,mRNA levels of INHβB and GnRHR were significantly up-regulated, whereas mRNA level of β-glycan was significantly down-regulated. B: The proteins levels of FSH, LH, ACVB, INHB, GnRHR and β-glycan were detected by western blotting. The results showed that FSH, LH, ACVB, INHB, GnRHR proteins were up-regulated by inhibin gene silencing. But the protein of β-glycan was down-regulated by inhibin silencing.
