Abstract:
Objective To study the effect of controlled ovarian Hyperstimulation(COH)on expression of AQP3 mRNA in mouse oocytes at metaphase Ⅱ. Methods Twenty female mice(6-7 weeks) were randomly allocated into 2 groups, mice in COH group were superovulated by intraperitoneal injection of 7.5 IU pregnant mare's serum gonadotropin(PMSG) followed by 5 IU human chorionic gonadotropin(HCG) after 46-48?h. Nothing was given to mice in control group and the estrus cycle was observed at 9?am everyday. 12-16?h following hCG injection (COH group) or at 8?am next day after the estrus (control group), mice were killed by cervical dislocation. The oviducts were excised.Cumulus masses were recovered from the dilated ampullae under a dissecting microscope,digested granulosa cells using hyaluronidase. Semi-quantitative real-time PCR of AQP3 mRNA in mouse MⅡoocytes was investigated with ?-actin as the internal control. Results Oocytes swelling assay showed that AQP3 mRNA expressed in mouse MⅡ oocytes. Using semi-quantitative real-time PCR, the expression of AQP3 mRNA was significantly decreased(P
