[Animal modeling] - Interventional effect and possible mechanism of resveratrol on premature ovarian failure in mice

  Objective To observe the intervention effect of resveratrol on premature ovarian failure in mice and elucidate its possible mechanism.

  Methods Forty two-month-old female mice were randomly divided into four groups: control group, model group, 20 mg/kg RES group, and 40 mg/kg RES group, with 10 mice in each group. Measurement of mouse body weight, ovarian weight, and ovarian/mouse relative weight ratio; HE staining was used to observe the changes in the number of follicles in mouse ovarian tissue; Detection of CyclinD1, Wnt1, and β- Catenin mRNA expression; Observation of ovarian tissue by immunohistochemical staining β- Caterin protein expression; Western blot was used to detect the expression of Mvh, Oct4, SOD2, Nrf2, Bax, and Bcl-2 proteins in ovarian tissue.

  Results The body weight, ovarian weight, and ovarian/mouse weight ratio of mice in the 20 mg/kg RES group and 40 mg/kg RES group were higher than those in the model group; Compared with the model group, the number of primordial follicles in the 20 mg/kg RES group and the 40 mg/kg RES group increased, while the number of atretic follicles decreased (P<0.05) 05), while cyclinD1, Wnt1, and β- The expression of Catenin mRNA increased (P<0.05) 05); Compared with the model group, in the ovarian tissue of mice in the 20 mg/kg RES group and the 40 mg/kg RES group β- The expression of Caterin positive protein increased in a concentration dependent manner; Compared with the model group, the expressions of Mvh, Oct4, SOD 2, Nrf2, and Bcl-2 proteins in the ovarian tissues of mice in the 20 mg/kg RES group and the 40 mg/kg RES group increased, while the expression of Bax decreased (P<0. 05) 01)。

  Conclusion Resveratrol has a protective effect on premature ovarian failure mice, and its mechanism may be related to inhibiting ovarian cell apoptosis and activating Wnt/ β- Catenin pathway promotes the recovery of ovarian function.
