摘要:

目的 观察益气血法经后增殖方通过p38MAPK/CK2/IκBα/NF-κB通路对控制性超促排卵(COH)大鼠卵巢GDF9分泌及颗粒细胞(GCs)凋亡的影响。 方法 建立COH大鼠模型,18只大鼠随机分为自然排卵组(NO组)、COH组、COH+经后增殖方组(COH+JHZZG组)。qRT-PCR和Western blot法检测p38MAPK、CK2、IκBα、NF-κB、GDF9 mRNA和蛋白的表达水平,TUNEL法检测卵巢GCs凋亡率。 结果 与NO组比较,COH组大鼠卵巢组织p38MAPK、NF-κB表达升高,CK2、IκBα、GDF9表达下降,卵巢GCs凋亡率升高,差异有统计学意义(P < 0.01);与COH组比较,COH+JHZZG组大鼠卵巢组织p38MAPK、NF-κB表达下降,CK2、IκBα、GDF9表达升高,差异有统计学意义(P < 0.01);卵巢GCs凋亡率下降,差异有统计学意义(P < 0.05)。 结论 益气血法经后增殖方通过p38MAPK/CK2/IκBα/NF-κB通路促进COH大鼠卵巢GDF9的分泌,抑制卵巢GCs的凋亡,从而提高COH卵细胞质量。

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.
