Human GDF9 ELISA Kit for Sandwich ELISA - ABIN414982
Zhang, Xu, Wu, Zou, Xu, Cao, Wei et al.: Dehydroepiandrosterone improves follicular fluid bone morphogenetic protein-15 and accumulated embryo score of infertility patients with diminished ovarian reserve undergoing in vitro fertilization: ... in Journal of ovarian research 2014
GDF9 expression was highest in primary growth follicles and gradually decreased during follicular development. Lowest level was found in fully grown follicles. It was maintained through fertilization and early embryonic development until gastrulation.
GDF9 c.169G>T (D57Y), c.546G>A (rs1049127), and BMP15 (show BMP15 ELISA Kits) rs79377927 (788_789insTCT) were associated with premature ovarian failure in the Chinese Hui population.
results support a model of activation for human GDF9 dependent on cumulin formation through heterodimerization with BMP15 (show BMP15 ELISA Kits). Oocyte-secreted cumulin is likely to be a central regulator of fertility in mono-ovular mammals.
GDF-9 and GDF-15 (show GDF15 ELISA Kits) levels may influence bone parameters in polycystic ovary syndrome
GDF9 and BMP15 (show BMP15 ELISA Kits) expression is reduced in primordial, primary, and secondary follicles in ovarian tissues of PCOS patients.
The arginine residue in the pre-helix loop of GDF9 homodimer may prevent the inhibition from its pro-domain or directly alter receptor binding, but this residue in GDF9 does not significantly affect the heterodimer activity.
Eleven unique copy number changes are identified in a total of 11 patients, including a tandem duplication of 475 bp, containing part of the GDF9 gene promoter region.
Data suggest up-regulation of mRNA for GDF9 and BMP15 (bone morphogenetic protein 15 (show BMP15 ELISA Kits)) in cumulus granulosa cells serves as biomarker for oocyte maturation, fertilization, embryo quality, and pregnancy in couples undergoing ICSI for male infertility.
These results suggest that COCs cultured with recombinant GDF9 in oocyte maturation medium improve oocyte developmental competence and subsequent developmental competence of cloned embryo in cattle.
Reduced expression of growth and differentiation factor-9 is associated with aggressive behaviour of clear-cell renal cell carcinoma.
Oocyte-derived GDF9 does not alter gap junction intercellular communication activity between human granulosa cells.
In organogenesis of the ovary, production of Dhh (show DHH ELISA Kits)/Ihh (show IHH ELISA Kits) in granulosa cells requires growth differentiation factor 9 from the oocyte.
The arginine residue in the pre-helix loop of GDF9 homodimer may prevent the inhibition from its pro-domain or directly alter receptor binding, but this residue in GDF9 does not significantly affect the heterodimer activity during heterodimer formation.
modified oocyte glycoproteins alter GDF9:BMP15 (show BMP15 ELISA Kits) expression modifying follicle development resulting in the generation of more follicles
A novel role for GDF9 in causing reproductive defects and suppressing tumor initiation in the Inha (show INHA ELISA Kits)(-/-) mouse model.
Embryo vitrification has no effect on ovarian morphology or expression of GDF9.
The results show that chronic unpredictable stress suppresses GDF9 expression.
show that purified mature regions of GDF9 and BMP15 (show BMP15 ELISA Kits) synergistically interact in a specific manner which is not dependent on the presence of a pro-region.
GDF9 may contribute to the variation observed in follicular development, ovulation rate, and fecundity between mammals
Data indicate that GDF-9 is absent in follicles of obese anovulatory/PCOS ovaries; upon treatment by heterotopic transplantation of gonadal adipose tissue from lean mice, expression of GDF-9 and ovulation appear to resume.
These results show that GDF9 and BMP15 (show BMP15 ELISA Kits) participate in cumulus expansion and that they stimulate MPF (show MSLN ELISA Kits) and MAPK (show MAPK1 ELISA Kits) activities in porcine oocytes during in vitro maturation.
Report temporal regulation of GDF9 mRNA expression in the oocyte, granulosa and theca cells of developing preovulatory follicles in the pig.
injection of porcine GDF-9 gene resulted in an increase in the number of primary, secondary and tertiary ovarian follicles
Porcine GDF9 gene was found to be highly expressed in immature oocytes and declined slowly during the oocyte maturation process
GDF9 may be not associated with pig litter size in extensive populations as per the studies of allele distributions of the four polymorphisms and pilot association in four breeds.
Immunization against GDF9 and BMP15 (show BMP15 ELISA Kits), alone or together, altered follicular development and ovulation rate in cattle.
GDF9 expression in the oocytes of calf ovaries was significantly higher than in those of the adult ovaries
GDF-9 mediates its effect through the pathway commonly activated by TGF beta (show TGFB1 ELISA Kits) and activin (show Actbeta ELISA Kits), but not that activated by many BMPs
Maternal GDF9 transcripts persisted during oocyte in vitro maturation and fertilization and in preimplantation embryo until the five- to eight-cell or morula stage, but transcription was not reactivated at the time of embryonic genome activation.
Oocyte- and granulosa cell-derived GDF9 may simultaneously promote theca cell proliferation and prevent premature differentiation of the theca interna during early follicle development.
Expression of BMP15 (show BMP15 ELISA Kits) (p < 0.01) and GDF9 (p < 0.05) mRNAs was more abundant in the small than the large antral follicles of Black Bengal goat.
GNRH1 (show GNRH1 ELISA Kits) and GDF9 genes could serve as genetic markers for litter size in goat breeding.
Mutation A959C in GDF9 gene has been associated with prolificacy.
Expression levels of follicular GDF9 and total ovarian BMPR1B (show BMPR1B ELISA Kits) were not different between the Lezhi black goat and the Tibetan goat.
These results provide further evidence that the GDF9 gene may be significantly correlated with high prolificacy in goats.
Growth factors synthesized by ovarian somatic cells directly affect oocyte growth and function. Growth differentiation factor-9 (GDF9) is expressed in oocytes and is thought to be required for ovarian folliculogenesis. GDF9 is a member of the transforming growth factor-beta superfamily.
