Simultaneous 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 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 کاملOocyte-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 کاملNonneoplastic Human Kidney Tissue Growth Factor Receptor Messenger RNA in Neoplastic and and Epidermal α Expression of Transforming Growth Factor
Using Northern blot analysis, we have demonstrated that mRNA for transforming growth factor a (TGF-a) was expressed in five malignant kidney tissue specimens but was not detected in their autologous nonneoplastic homologues. In addition, the expression of epidermal growth factor (EGF) receptor mRNA in these malignant tissues was 2to 3-fold greater than in nontransformed tissues. In two cases ex...
متن کاملSynergistic roles of bone morphogenetic protein 15 and growth differentiation factor 9 in ovarian function.
Knockout mouse technology has been used over the last decade to define the essential roles of ovarian-expressed genes and uncover genetic interactions. In particular, we have used this technology to study the function of multiple members of the transforming growth factor-beta superfamily including inhibins, activins, and growth differentiation factor 9 (GDF-9 or Gdf9). Knockout mice lacking GDF...
