Growth 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 کاملPlatelet-activating factor stimulates prostaglandin synthesis in cultured cells.
The effects of platelet-activating factor (1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine) on phospholipase activity were studied in aortic smooth muscle cells and renal epithelial cells. When platelet-activating factor was added to cells prelabeled with [3H]arachidonic acid, it induced rapid hydrolysis of phospholipids. Up to 28% of incorporated [3H]arachidonic acid was released into the mediu...
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 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 کاملProstaglandin F2α stimulates growth of skeletal muscle cells via an NFATC2-dependent pathway
Skeletal muscle growth requires multiple steps to form large multinucleated muscle cells. Molecules that stimulate muscle growth may be therapeutic for muscle loss associated with aging, injury, or disease. However, few factors are known to increase muscle cell size. We demonstrate that prostaglandin F2alpha (PGF2alpha) as well as two analogues augment muscle cell size in vitro. This increased ...
