Potential Therapeutic Effect of Bee Pollen and Metformin Combination on Testosterone and Estradiol Levels, Apoptotic Markers and Total Antioxidant Capacity in A Rat Model of Polycystic Ovary Syndrome

BACKGROUND: Polycystic ovary syndrome (PCOS) is associated with metabolic disorder as well as infertility. Many traditional remedies have been reported to show estrogenic and antioxidant potential.

description BACKGROUND: Polycystic ovary syndrome (PCOS) is associated with metabolic disorder as well as infertility. Many traditional remedies have been reported to show estrogenic and antioxidant potential. Bee pollen is a natural com- pound, reported as one such remedy. The present study aimed to investigate the effects of BP extract and metformin (MET) on estradiol (E2) and testosterone (T) levels, apoptotic markers, and total antioxidant capacity (TAC) inarat model of PCOS. MATERIALS AND METHODS: In this experimental study, 54 female Wistar (n=6/group) rats received 2 mg of estradiol valerate (EV) intramuscularly and 6 additional rats were considered the control without EV injection. The rats were treated with BP (50, 100, and 200 mg/kg), MET (300 mg/kg) and BP+MET (50 BP+300 MET, 100 BP+300 MET, and 200 BP+300 MET mg/kg). Serum levels of E2 and T were assessed by ELISA method. TAC of serum was also determined. The expressions of Bcl-2, Bax and Caspase-3 (Cas-3), and Sirt-1 genes were evaluated by real-time poly- merase chain reaction (PCR). Data were statistically analyzed using one-way ANOVA. RESULTS: In the untreated PCOS group E2 and T levels (P<0.01), and Bcl-2 (P=0.007) expression were increased, but TAC (P=0.002) and expression of Bax (P=0.001), Cas-3 and Sirt1 (P<0.01) were decreased significantly. The levels of E2 and T, as well as the expressions of Bcl-2 were decreased in all treated groups compared to the untreated PCOS group (P<0.01). On the other hand, TAC and expression of Bax, Cas-3 and Sirt1 were increased in the BP- and MET-treated groups (P<0.05). CONCLUSION: BP and MET synergistically improved serum E2, T and TAC levels, and expression of apoptotic genes.
