تحقیق حاضر به منظور بررسی پلی مورفیسم ژن bmp15 و تأثیر آن بر میزان دوقلوزایی و صفات رشد از تولد تا 15 ماهگی در گوسفند نژاد سنجابی انجام گرفت. برای انجام این پژوهش از 100 رأس گوسفند سنجابی (78 رأس میش و 22 رأس قوچ) ایستگاه اصلاح نژاد مهرگان کرمانشاه به طور تصادفی خون گیری انجام گرفت. بر اساس نتایج به دست آمده در جایگاه bmp15 80 درصد حیوانات ژنوتیپ mm و 20 درصد نیز ژنوتیپ nn را نشان دادند. در این...
This study aimed to describe the abundance and localization of BMP2, BMP6, BMP15, GDF9, BMPR1A, BMPR1B, BMPR2 and TGFBR1 mRNA during pig preovulatory follicular development and to evaluate their implication in improving follicular maturity in the preovulatory period preceding the second versus first post-weaning oestrus. Oocytes, granulosa (GC) and theca cells (TC) were recovered from antral fo...
Germ cell nuclear factor (GCNF) is an orphan nuclear receptor that plays important roles in development and reproduction, by repressing the expression of essential genes such as Oct4, GDF9, and BMP15, through binding to DR0 elements. Surprisingly, whereas recombinant GCNF binds to DR0 sequences as a homodimer, endogenous GCNF does not exist as a homodimer but rather as part of a large complex t...
introduction one of the most important sources of the red meat in iran is the meat produced from sheep. increasing lamb per ewe considered as a strategy for improving the efficiency for sheep production, although reproduction traits have low heritability. several genes associated with reproduction were investigated in the recent years. the bmp 15 gene and its paralog gdf 9 and receptor, bmpr-ib...
The families of TGF-β proteins are the most important growth factors in the ovary for growth and differentiation of early ovarian follicles. Three related oocyte-derived members of the transforming growth factor-β superfamily namely growth differentiation factor 9 (GDF9), BMP15 and BMPR-IB have been shown to be essential for follicular growth and ovulation. Different mutations in the GDF9 gene ...
