The rapid evolution of reproductive proteins might be driven by positive Darwinian selection. The bone morphogenetic protein family is the largest within the transforming growth factor (TGF) superfamily. A little have been known about the molecular evolution of bone morphogenetic proteins exhibiting potential role in mammalian reproduction. In this study we investigated mammalian bone morphogenetic proteins using maximum likelihood approaches of codon substitutions to identify positive Darwinian selection in various species...

Recent findings suggest that ephrinA5 (Efna5) has a novel role in female mouse fertility, in addition to its well-defined role as a neurogenesis factor. Nevertheless, its physiological roles in ovarian granulosa cells (GC) have not been determined. In this study, mouse GC were cultured and transfected with ephrin A5 siRNA and negative control to determine the effects of Efna5 on GC apoptosis, proliferation, cell cycle progression, and related signaling pathways. To understand the mode signaling, the mRNA expression levels of Efna5 receptors (Eph receptor A5, Eph receptor A3, Eph receptor A8, and Eph receptor B2) were examined...

BACKGROUND/AIMS: Bone morphogenetic protein 15 (BMP15) and growth differentiation factor 9 (GDF9), which are secreted by oocytes, are important regulators of follicular growth and development and ovarian function. These two factors can regulate the proliferation and apoptosis of cumulus cells via modulation of the Smad signaling pathway. Studies have shown that BMP15 and GDF9 can affect the level of miR-375, whereas the target gene of miR-375 is BMPR2, the type II receptor of BMP15 and GDF9...

Cumulus-oocyte complexes (COCs) release factors potentially involved in follicular growth and development, such as growth and differentiation factor 9 (GDF9), bone-morphogenetic protein 15 (BMP15), follistatin (FST) and cathepsins (CTSs). Moreover, the quality of the oocytes and follicles may be related to both the lipid composition of the follicle cells and follicular fluid. One of the lipids, locally regulating the reproductive functions in ovaries of cattle, is lysophosphatidic acid (LPA). In this study, the expression was investigated of the genes for LPA and other factors in COCs of follicles at different stages of development and regression...

Growth and differentiation factor 9 (GDF9) and bone morphogenetic protein 15 (BMP15) are oocyte-secreted factors with a leading role in the control of ovarian function in female reproduction, modulating both the cell fate of the somatic granulosa cells and the quality and developmental competence of the egg. This short review aims to consolidate the molecular aspects of GDF9 and BMP15 and their integral actions in female fertility to understand particularly their effects on oocyte quality and fetal growth. The significant consequences of mutations in the GDF9 and BMP15 genes in women with dizygotic twins as well as the clinical relevance of these oocyte factors in the pathogenesis of primary ovarian insufficiency and polycystic ovary syndrome are also addressed...

Oocytes from prepubertal animals have a reduced ability to undergo embryo development and produce viable offspring. The present work used an ovine model consisting of oocytes derived from adult and prepubertal donors to assess the molecular status of oocytes and preimplantation embryos with different developmental competence. The lower potential of oocytes of young donors was confirmed in terms of in vitro developmental capabilities and kinetics. A panel of genes including maternal effect (DPPA3, GDF9, NMP2, ZAR1) and housekeeping genes (ACTB, RPL19, SDHA, YWHAZ, ATP1A1), genes involved in DNA methylation (DNMT1, DNMT3A, DNMT3B), genomic imprinting (IGF2R), pluripotency (NANOG, POU5F1) and cell cycle regulation (CCNB1, CDK1, MELK) was relatively quantified...

Follicle culture provides a condition which can help investigators to evaluate various aspects of ovarian follicle growth and development and impact of different components and supplementations as well as presumably application of follicle culture approach in fertility preservation procedures. Mesenchymal Stem Cells (MSCs), particularly those isolated from menstrual blood has the potential to be used as a tool for improvement of fertility. In the current study, a 3D co-culture system with mice preantral follicles and human Menstrual Blood Mesenchymal Stem Cells (MenSCs) using either collagen or alginate beads was designed to investigate whether this system allows better preantral follicles growth and development...

Human endothelial progenitor cells (EPCs) have been applied to regenerative medicine for their roles in angiogenesis as well as neovascularization, and these angiogenetic functions have beneficial effects on maturation of ovarian follicles. However, little information is available on whether EPCs on culture systems affect oocyte maturation and subsequent embryo development. Therefore, the objective of this study was to investigate the effect of EPC co-culture on porcine oocytes during in vitro maturation (IVM) and subsequent embryo development, and to examine gene expression in cumulus cells, oocytes and blastocysts...

Although studies have shown that di(2-ethylhexyl) phthalate (DEHP) can disrupt ovarian function, few reports have focused on follicular development in mice between the weaning period and maturity, especially with respect to microRNA (miRNA) expression. In this study, 21-day-old ICR mice were administered DEHP at doses of 0, 100, 400, and 1600 mg/(kg d) for 6 weeks by gavage. After DEHP administration, a significant decrease in the expression of follicle development-related factors (including c-kit, kitl, gdf9, and atm) was observed by quantitative real-time PCR (RT-PCR), but no significant difference in the proteins encoded by these genes was observed by Western blot...

In vitro culture of ovarian follicles is a new technique in reproductive technology, which helps in understanding the process of folliculogenesis. The in vitro culture of follicles could be carried out using three-dimensional (3D) natural scaffolds that mimic the ovarian tissue stroma. Selection of the right matrix and culture media in these scaffolds could increase the survival and maturation of the follicles. In this work, the applicability of matrigel-alginate (MA) and fibrin-alginate (FA) 3D scaffolds for folliculogenesis was assessed...

The use of supplements, such as porcine follicular fluid (pFF), fetal bovine serum and human serum albumin are widely used during in vitro maturation (IVM) in different species but these supplements contain undefined components that cause technical difficulties in standardization and influence the efficiency of IVM. Knockout serum replacement (KSR) is a synthetic protein source, without any undefined growth factors or differentiation-promoting factors. Therefore, it is feasible to use KSR as a defined component for avoiding effects of unknown molecules in an IVM system...

Background: The presence of different missense mutations in sheep breeds have shown that the bone morphogenetic protein receptor 1B (BMPR1B), bone morphogenetic protein 15 (BMP15) and growth differentiation factor 9 (GDF9) genes play a vital role in ovulation rate and prolificacy in ewes. Therefore, the present study aims to investigate BMPR1B, BMP15 and GDF9 gene mutations in prolific ewes of Iranian fat-tailed Lori-Bakhtiari sheep. MATERIALS AND METHODS: In the present experimental study, genomic DNA was extracted from whole blood of 10 prolific Lori-Bakhtiari ewes with at least two twinning records in the first four parities to identify point mutations of the BMPR1B, BMP15 and GDF9 genes, using DNA sequencing...

Litter size, which is a complex economic trait in sheep, is affected by polygenes. Hu sheep are a prolific native breed in China and also an ideal resource for studying the genetic mechanism that controls litter size in sheep. In this study, we investigated the genetic effects of candidate genes on litter size in a large experimental population (n = 2021) of Hu sheep. A total of 23 single nucleotide polymorphisms (SNPs) including six reported major mutations (FecB, FecXI , FecXB , FecXH , FecGI , and FecGH ) and 17 novel SNPs in 10 candidate genes involved in reproduction were genotyped using KASPar technology...
