ABSTRACT
It has been hypothesized that blastocyst integrin expression changes can affect the spontaneous miscarriage in polycystic ovarian syndromes [PCOS]. In this study, the profile of integrin genes and proteins was investigated on blastocyst of the PCOS experimental mouse model. 30 NMRI female mice were equally divided into 3 groups control, experimental [PCOS that was injected estradiol valerate [40 mg/kg]]. After 8 weeks, each group was hyper stimulated by PMSG and HCG. Vaginal plaque was checked, and mice were investigated 5 days after the test. Progesterone and estradiol levels were determined; alpha4, alpha v, beta 1 and beta 3 integrin genes and protein of blastocysts were examined by real time PCR method and immunohistochemistry, respectively. Estradiol level was significantly increased [p genes' expressions alphav, beta 3, beta 1 and alpha 4 in PCOS to control group was 0.479 +/- 0.01, 0.5 +/- 0.001, 2.7 +/- 0.4 and 1.023 +/- 0.2 respectively. Genes expression showed a great difference [p integrin proteins expressed in all groups but intensity of these proteins in PCOS groups, was lower than other groups. Pattern of alpha v and beta3 integrins expression on the mouse blastocyst surface has an important effect during the implantation window. This pattern has changed in PCOS model and might have a great influence on implantation failure. Therefore, this experimental study suggests that a great attention to this problem may be essential in patients who are involved
