Growth differentiation factor 9 signaling requires ERK1/2 activity in mouse granulosa and cumulus cells.
Ovarian folliculogenesis is driven by the combined action of endocrine cues and paracrine factors. The oocyte secretes powerful mitogens, such as growth differentiation factor 9 (GDF9), that regulate granulosa cell proliferation, metabolism, steroidogenesis and differentiation. This study investigated the role of the epidermal growth factor receptor (EGFR)-extracellular signal-regulated kinase ...
متن کاملCharacterization of recombinant human growth differentiation factor-9 signaling in ovarian granulosa cells.
Growth differentiation factor-9 (GDF9) is an oocyte secreted paracrine factor essential for mammalian ovarian folliculogenesis. Like other members of the transforming growth factor-beta (TGFbeta) superfamily, GDF9 is synthesized as a prepropeptide which needs processing by furin-like proteases to result in an active mature protein. We have previously characterized a preparation of unpurified re...
متن کاملGrowth differentiation factor-9 stimulates inhibin production and activates Smad2 in cultured rat granulosa cells.
Ovarian inhibin production is stimulated by FSH and several TGFbeta family ligands including activins and bone morphogenetic proteins. Growth differentiation factor-9 (GDF-9) derived by the oocyte is a member of the TGFbeta/activin family, and we have previously shown that GDF-9 treatment stimulates ovarian inhibin-alpha content in explants of neonatal ovaries. However, little is known about GD...
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 کاملGrowth Differentiation Factor 9 (GDF9) Suppresses Follistatin and Follistatin-Like 3 Production in Human Granulosa-Lutein Cells
BACKGROUND We have demonstrated that growth differentiation factor 9 (GDF9) enhances activin A-induced inhibin β(B)-subunit mRNA levels in human granulosa-lutein (hGL) cells by regulating receptors and key intracellular components of the activin signaling pathway. However, we could not exclude its effects on follistatin (FST) and follistatin-like 3 (FSTL3), well recognized extracellular inhibit...
