چکیده

هدف: هدف این پژوهش بررسی رابطه بین غلظت BPA موجود در مایع فولیکولی و تاثیر آن بر روی تغییرات بیان ژن‌‌هایNotch1، Notch2، Notch3، Caspase-3 و Caspase-7 در سلول‌‌های کومولوس زنان نابارور با پاسخ تحریک ضعیف تخمدان (POR Response) به دنبال تحریک تخمدانی با پروتکل آنتاگونیست هورمون آزادکننده گنادوتروپین (GnRH) است.
مواد و روش: این مطالعه مورد-شاهدی بر روی 80 بیمار زن POR با سن کم‌تر از 35 سال انجام شد که در روز پانکچر تخمدان دارای 9-4 تخمک بالغ بودند. بیماران در دو گروه دسته‌بندی شدند. گروه اول شامل 40 زن POR بودند که از ظروف پلاستیکی استفاده می‌‌کردند و گروه دوم شامل 40 زن POR بودند
که استفاده کم‌تری از ظروف پلاستیکی داشتند. تغییرات بیان ژن در سلول‌‌های کومولوس با استفاده از
Real time PCR ارزیابی شد.
نتایج: میزان بیان ژن‌‌هایNotch1، Notch2 و Notch3 در گروه اولیه به طور معنی‌‌داری کم‌تر از گروه دوم بود (05/0 .(p< در مقابل، میزان بیان Caspase-3 و Caspase-7 در بیماران POR در گروه اول در مقایسه با گروه دوم بالاتر بود (05/0 .(p<از طرف دیگر، همبستگی آماری معنی‌‌داری (05/0 (p<بین سطح بیان ژن‌هایNotch1، Notch2، Notch3، Caspase-3 و Caspase-7 با کیفیت تخمک بین دو گروه وجود داشت. میزان غلظت BPA در مایعات فولیکولی گروه اول در مقایسه با گروه دوم بیشتر بود (05/0 .(p<
نتیجه‌گیری: تغییرات بیان ژن‌‌های مورد مطالعه در بیماران POR با افزایش غلظت BPA ارتباط مثبت معناداری دارد. افزایش غلظت  BPAرا می‌‌توان به عنوان یک عامل موثر در کاهش تولیدمثل و کاهش رشد تخمک در نظر گرفت.

چکیده [English]

Introduction: The aim of this study was to investigate the relationship between BPA concentration and alterations of Notch1, Notch2, Notch3, Caspase-3 and Caspase-7 genes expression in the cumulus cells of infertile women with poor ovarian stimulation response (POR) following the antagonist protocol.
Materials and Methods: In this case-control study performed on 80 POR patients under 35 years of age, with 4-9 oocyte in puncture date, patients were divided into two groups. The first group consisted of 40 POR women who used plastic containers and the second group consisted of 40 POR women who used less plastic containers. Changes in the expression of Notch and Caspase genes in cumulus cells were evaluated using
Q-PCR technique.
Results: In the POR patients, the expression of Notch1-3 genes in the first group was significantly lower than the second group (p<0.05). In contrast, the expression of Caspase-3 and Caspase-7 genes in the first group was significantly higher than the second group (p<0.05).On the other hand, in both groups, was a statistically significant correlation (p<0.05) between the expression levels of Notch1-3, Caspase-3 and Caspase-7 genes and quality of Oocytes. Also, concentration of BPA in the follicular fluids of the first group was higher compared to the second group (p<0.05).
Conclusion: Alterations in the expression of Notch and Caspase genes in POR patients are associated with increased BPA concentration. Also, Increasing of the BPA concentration can be considered as an effective factor on the reducing of reproduction and oocyte growth.
