Abstract:

Objective To explore the effects of Jinghou Zengzhi Granules(JHZZG), on ovarian GDF9 secretion and granulosa cells(GCs) apoptosis in controlled ovarian hyperstimulation(COH) rats through p38MAPK/CK2/IκBα/NF-κB pathway. Methods A model of COH rats was prepared and 18 rats were randomly divided into 3 groups, including natural ovulation group(NO group), COH group, and COH+JHZZG group. The expression of p38MAPK, CK2, IκBα, NF-κB, GDF9 mRNA and protein were detected by qRT-PCR and Western blot, and the apoptosis rate of ovarian GCs by TUNEL. Results Compared with the NO group, the expression of p38MAPK and NF-κB in the ovarian tissue of rats in the COH group increased, while the expression of CK2, IκBα and GDF9 decreased, and the apoptosis rate of ovarian GCs increased (all P < 0.01). Compared with the COH group, the expression of p38MAPK and NF-κB in the ovarian tissue of rats in the COH+JHZZG group decreased, while the expression of CK2, IκBα and GDF9 increased (all P < 0.01), and the apoptosis rate of ovarian GCs decreased (P < 0.05). Conclusion Jinghou Zengzhi Granules could promote the secretion of ovarian GDF9 and inhibit the apoptosis of ovarian GCs of COH rats through p38MAPK/CK2/IκBα/NF-κB signaling pathway, which thereby improve the quality of COH oocytes.
