| 目的探究重组人生长激素(r-hGH)联合脱氢表雄酮(DHEA)对卵巢低反应(POR)小鼠模型干预效果及对生长分化因子-9(GDF-9)、晚期糖基化终末产物(AGE)及其受体(RAGE)的影响。方法100只小鼠随机分为对照组、模型组、r-hGH组、DHEA组和r-hGH+DHEA组。使用慢性制动应激法建立卵巢早衰及卵巢低反应小鼠模型,对照组用等量的溶剂处理。r-hGH组和DHEA组分别使用r-hGH和DHEA干预,r-hGH+DHEA组进行联合干预。检测血清抗苗勒管激素(AMH)水平。使用HE染色法检测卵巢中卵泡数量。qRT-PCR和Western blotting检测卵巢组织中AGE、RAGE和卵泡中GDF-9 mRNA和蛋白水平。结果建模后,小鼠血清AMH、卵泡数目以及GDF-9 mRNA和蛋白水平降低,而AGE、RAGE mRNA和蛋白水平升高(P＜0.05)。r-hGH组和DHEA组的AMH、卵泡数目以及GDF-9 mRNA和蛋白水平高于模型组,而AGE、RAGE mRNA和蛋白水平低于模型组(P＜0.05)。r-hGH+DHEA组AMH、卵泡数目以及GDF-9 mRNA和蛋白水平高于r-hGH组和DHEA组,而AGE、RAGE mRNA和蛋白水平低于r-hGH组和DHEA组(P＜0.05)。结论r-hGH联合DHEA对POR小鼠具有较好干预效果,与下调卵巢中AGE、RAGE并促进GDF-9 mRNA和蛋白的表达有关。 |
| 英文摘要: |
| To investigate the effect of recombinant human growth hormone (r-hGH) combined with dehydroepiandrosterone (DHEA) on the ovarian hyporesponsive mouse model and its effect on the expression ofgrowth differentiation factor-9 (GDF-9), advanced glycation end product (AGE) and receptor of advanced glycation endproducts (RAGE). Methods100 mice were randomly divided into control group, model group, r-hGH group, DHEA group and r-hGH+DHEA group. A model of premature ovarian failure and ovarian hyporesponsiveness was established using chronic brake stress. The control group was treated with the same amount of solvent. The r-hGH group and DHEA group were treated with r-hGH and DHEA respectively. The mice in the r-hGH+DHEA group were treated with r-hGH and DHEA. The level of anti-Mullerian hormone (AMH) in the serum was measured. The number of follicles in the ovary was measured using HE staining. qRT-PCR and Western blotting were used to detect the levels of AGE, RAGE GDF-9 mRNA and protein in follicles in ovarian tissue. ResultsAfter modeling, mouse serum AMH, follicle number, AGE, RAGE and GDF-9 mRNA and protein levels were significantly reduced (P＜0.05). The AMH, follicle number, AGE, RAGE, and GDF-9 mRNA and protein levelsin the r-hGH group and DHEA group were significantly higher than those in the model group (P＜0.05). The AMH, follicle number, AGE, RAGE, and GDF-9 mRNA and protein levels in the r-hGH+DHEA group were significantly higher than those in the r-hGH and DHEA groups (P＜0.05). ConclusionR-hGH combined with DHEA has a good intervention effect on POR mouse model, which may be related to its down-regulation of AGE and RAGE mRNA levels in ovary and promotion of GDF-9 expression. |
