左归丸对免疫性卵巢早衰模型小鼠卵巢GDF-9/Smad2信号转导的影响
Effect of Zuogui Pill on GDF-9/Smad2 Signal Transduction In Premature Ovarian Failure Model Mice
摘要
Abstract
Objective To observe the effect of Zuogui Pill (ZP) on growth differentiation factor-9 (GDF-9)/Smad2 signal transduction in premature ovarian failure (POF) model mice,and to study its mechanism for treating POF.Methods Totally 84 female Balb/c mice were randomly divided into the blank control group (n =12),the model group (n =24),the ZP group (n =24),the diethylstilbestrol group (n =24).The POF model was established by subcutaneously multi-point injecting zona pellucida 3 (ZP3) in mice of all groups except the blank control group.ZP at the daily dose of 2.7 g/kg was administered to mice in the ZP group by gastrogavage,once per day,6 times per week for 4 or 8 successive weeks.Diethylstilbestrol solution at the daily dose of 0.15 mg/kg was administered to mice in the diethylstilbestrol group by gastrogavage,once per day,6 times per week for 4 or 8 successive weeks.The ratio of ovarian growth follicles was observed.Protein expressions of GDF-9 and Smad2 in ovarian tissue were detected by immunohistochemical assay and Western blot.Results Compared with the blank control group,the ovarian growth follicle ratio,and protein expressions of GDF-9 significantly decreased in the model group (P ＜0.05).Compared with the model group at the same time point,ovarian growth follicle ratio and GDF-9 protein expression significantly increased in the ZP group and the diethylstilbestrol group (P ＜0.05).Smad2 protein expression increased in the ZP group at week 8 (P ＜0.05).Conclusions The incidence of POF might be associated with insufficient expression of GDF-9 protein in ovarian tissue,hypofunction of GDF-9/Smad2 signal transduction pathway,which resulted in ineffectively recruited primordial follicles and follicular atresia.ZP could increase expression of GDF-9 protein possibly via regulating the follicle growth and development through GDF-9/Smad2 signal transduction pathway,thus playing a role in treating POF.关键词
