Oocyte-specific expression of growth/differentiation factor-9.
Growth/differentiation factor-9 (GDF-9) is a previously described member of the transforming growth factor-beta superfamily expressed specifically in the ovary in adult mice. Using in situ hybridization methods, we have localized the expression of GDF-9 messenger RNA (mRNA) exclusively to oocytes. GDF-9 mRNA was detected in oocytes at all stages of follicular development, except in primordial f...
متن کاملScreening for FecGH Mutation of Growth Differentiation Factor 9 Gene in Iranian Ghezel Sheep Population
Background Ghezel sheep are highly prolific and one of the local sheep breeds in Iran and Turkey. Growth differentiation factor-9 (GDF9) gene has been found to be essential for growth and differentiation of early ovarian follicles. Novel mutations in GDF9 have been associated with increased ovulation rates and high litter sizes in heterozygous carriers. Therefore, fecundity gene for GDF9 (FecGH...
متن کاملSimultaneous Presence of G1 and G4 Mutations in Growth Differentiation Factor 9 Gene of Iranian Sheep
The fecundity in sheep has been much interested for producers due to its economical importance. Growth differentiation factor 9 (GDF9) is an autosomal gene with over dominance effect for twosingle nucleotide polymorphisms(SNPs), which resulted in sterility in homozygote mutant ewes and additive effect for three SNPs, without showing sterility event. In the present study, DNA was extracted from ...

متن کاملPlatelet factor 4 modulates the mitogenic activity of basic fibroblast growth factor.
Basic fibroblast growth factor (bFGF) has been shown to stimulate cell proliferation after vascular injury. The mitogenic activity of bFGF requires interactions with both a high affinity receptor and a cell-surface heparan sulfate proteoglycan. We tested the ability of platelet factor 4 (PF 4) and other platelet heparin-binding proteins to modulate bFGF-stimulated [3H]thymidine incorporation in...
