fertility rate is an economically important trait in sheep, which is influenced by genetic and environment. so far, three genes have been identified that affects this trait, one of them would be the bmp family, the most famous one is bmp15. different mutations in the bmp15 gene, increases reproductive performance and growth rate in sheep. the aim of this study was to investigate the genetic and...

background: premature ovarian failure (pof) is an ovarian defect characterized by the premature depletion of ovarian follicles before the age of 40, representing one major cause of female infertility. mutations in bone morphogenetic protein 15 (bmp15) and growth differentiation factor 9 (gdf9) have been shown to be associated with pof. methods: genomic dna was isolated from 52 idiopathic premat...

this study was conducted to detect polymorphism of gene bmp15, a member of transforming growthfactor β (tgfβ) family which has a crucial role in controlling the ovarian follicles development,ovulation rate and fertility. samples were randomly selected from 91 najdi goats in 3 geographicallocations, northwest, southeast and center of khuzestan province. after dna extraction, amplification of235 ...

Premature ovarian failure (POF) is an ovarian defect characterized by the premature depletion of ovarian follicles in individuals <40 years old, and is a major cause of infertility in females. Genetic factors are considered to be responsible for the development of POF, however, the exact pathogenesis remains to be elucidated in the majority of cases. In the present study, the single nucleotide ...

BACKGROUND The effect of hormonal estrus induction on maternal effect (MATER - maternal antigen that embryo requires, ZAR-1 - zygote arrest 1, and BMP15 - bone morphogenetic protein 15) and apoptosis-related genes expression (BCL-2 and BAX) in porcine cumulus-oocyte complexes (COCs) and selected follicular parameters was investigated in this study. METHODS Gilts were divided into three groups...

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...

Goat farming in Bangladesh is primarily centred on indigenous Black Bengal goat, a highly prolific breed. Searching for genetic markers associated with prolificacy this breed vital the country’s goat breeding industry. However, there are no reports polymorphisms fertility of Bangladeshi goats. This study investigated two major fecundity genes-bone morphogenetic protein 15 (BMP15) and growth dif...

BMP15 and GDF9 are two oogenesis specific genes play a pivotal role in female fertility in mammals and potential for improvement of prolificacy in marker-assisted selection. The aim of present research was to investigate the variation and association between BMP15 and GDF9 polymorphism and litter size in Markhoz goats. The sequence variability of the different amplified fragments utilized for g...
