Growth differentiation factor-9 stimulates proliferation but suppresses the follicle-stimulating hormone-induced differentiation of cultured granulosa cells from small antral and preovulatory rat follicles. (1/115)

In addition to pituitary gonadotropins and paracrine factors, ovarian follicle development is also modulated by oocyte factors capable of stimulating granulosa cell proliferation but suppressing their differentiation. The nature of these oocyte factors is unclear. Because growth differentiation factor-9 (GDF-9) enhanced preantral follicle growth and was detected in the oocytes of early antral and preovulatory follicles, we hypothesized that this oocyte hormone could regulate the proliferation and differentiation of granulosa cells from these advanced follicles. Treatment with recombinant GDF-9, but not FSH, stimulated thymidine incorporation into cultured granulosa cells from both early antral and preovulatory follicles, accompanied by increases in granulosa cell number. Although GDF-9 treatment alone stimulated basal steroidogenesis in granulosa cells, cotreatment with GDF-9 suppressed FSH-stimulated progesterone and estradiol production. In addition, GDF-9 cotreatment attentuated FSH-induced LH receptor formation. The inhibitory effects of GDF-9 on FSH-induced granulosa cell differentiation were accompanied by decreases in the FSH-induced cAMP production. These data suggested that GDF-9 is a proliferation factor for granulosa cells from early antral and preovulatory follicles but suppresses FSH-induced differentiation of the same cells. Thus, oocyte-derived GDF-9 could account, at least partially, for the oocyte factor(s) previously reported to control cumulus and granulosa cell differentiation.  (+info)

Expression of growth and differentiation factor-9 in the ovaries of fetal sheep homozygous or heterozygous for the inverdale prolificacy gene (FecX(I)). (2/115)

Abnormal follicular and oocyte growth in ovaries of sheep homozygous (II) for the Inverdale gene, FecX(I), suggest that this gene may influence a fundamental event in initiation of folliculogenesis, with two copies of the gene inhibiting growth at the primordial/primary stage. In addition, striking similarities in ovarian morphology between mice deficient in growth and differentiation factor-9 (GDF-9) and II sheep suggest a relationship between the FecX(I) gene and GDF-9 function in the ovary. Therefore, it was hypothesized that GDF-9 mRNA expression would be inhibited in ovaries of II fetal sheep. To test this hypothesis, in situ hybridization was used to characterize GDF-9 mRNA expression in ovaries of homozygous (II), heterozygous (I+), and control (++) fetal sheep at Day 135 of gestation. GDF-9 mRNA expression was localized exclusively to oocytes from the type 1 follicle stage onward in all genotypes and is the first demonstration of GDF-9 mRNA expression in ovaries of fetal sheep. In addition, GDF-9 mRNA expression was detected in oocytes of abnormal type 2 follicles in the ovaries of II sheep. Thus, it does not appear that inhibition of GDF-9 gene expression is the mechanism of action whereby the FecX(I) gene exerts its influence. However, the possibility of translation at specific stages of follicular development cannot presently be ruled out. In addition, the FecX(I) gene may be involved, either directly or indirectly, in regulating expression of receptors for GDF-9. At present, however, neither the FecX(I) gene product nor the GDF-9 receptor has been isolated or characterized.  (+info)

Growth differentiation factor-9 stimulates progesterone synthesis in granulosa cells via a prostaglandin E2/EP2 receptor pathway. (3/115)

Growth differentiation factor-9 (GDF-9), an oocyte-secreted member of the transforming growth factor beta superfamily, progesterone receptor, cyclooxygenase 2 (Cox2; Ptgs2), and the EP2 prostaglandin E(2) (PGE(2)) receptor (EP2; Ptgerep2) are required for fertility in female but not male mice. To define the interrelationship of these factors, we used a preovulatory granulosa cell culture system in which we added recombinant GDF-9, prostaglandins, prostaglandin receptor agonists, or cyclooxygenase inhibitors. GDF-9 stimulated Cox2 mRNA within 2 h, and PGE(2) within 6 h; however, progesterone was not increased until 12 h after addition of GDF-9. This suggested that Cox2 is a direct downstream target of GDF-9 but that progesterone synthesis required an intermediate. To determine whether prostaglandin synthesis was required for progesterone production, we analyzed the effects of PGE(2) and cyclooxygenase inhibitors on this process. PGE(2) can stimulate progesterone synthesis by itself, although less effectively than GDF-9 (3-fold vs. 6-fold increase over 24 h, respectively). Furthermore, indomethacin or NS-398, inhibitors of Cox2, block basal and GDF-9-stimulated progesterone synthesis. However, addition of PGE(2) to cultures containing both GDF-9 and NS-398 overrides the NS-398 block in progesterone synthesis. To further define the PGE(2)-dependent pathway, we show that butaprost, a specific EP2 agonist, stimulates progesterone synthesis and overrides the NS-398 block. In addition, GDF-9 stimulates EP2 mRNA synthesis by a prostaglandin- and progesterone-independent pathway. Thus, GDF-9 induces an EP2 signal transduction pathway which appears to be required for progesterone synthesis in cumulus granulosa cells. These studies further demonstrate the importance of oocyte-somatic cell interactions in female reproduction.  (+info)

Growth differentiation factor-9 stimulates rat theca-interstitial cell androgen biosynthesis. (4/115)

Growth differentiation factor-9 (GDF-9) was shown recently to be essential for early follicular development, including the appearance of the theca layer. Theca cells provide the androgen substrate for aromatization and estrogen production by granulosa cells. Using biologically active recombinant GDF-9 (rGDF-9) and an androgen-producing immortalized theca-interstitial cell (TIC) line or primary TIC, we have examined the action of this paracrine hormone on theca cell steroidogenesis. The effect of GDF-9 on TIC progesterone synthesis was marginal and inconsistent in the primary cultures. In immortalized theca cells, GDF-9 attenuated the forskolin-stimulated progesterone accumulation. More significantly, this oocyte-derived growth factor enhanced both basal and stimulated androstenedione accumulation in the primary and transformed TIC cultures. The effects of GDF-9 on steroidogenesis by preovulatory follicles were relatively modest. Likewise, it did not affect the maturation of follicle-enclosed oocytes. The effect of GDF-9, an oocyte product, on TIC androgen production suggests a regulatory role of the oocyte on theca cell function and hence on follicle development and differentiation. This direct effect of GDF-9 on thecal steroidogenesis is consistent with its recently demonstrated actions on thecal cell recruitment and differentiation.  (+info)

Bone morphogenetic protein-15. Identification of target cells and biological functions. (5/115)

In developing ovarian follicles, the regulation of cell proliferation and differentiation is tightly coordinated. Precisely how this coordination is achieved is unknown, but recent observations have suggested that molecules emitted by the oocyte are involved in the process. The newly discovered oocyte-specific growth factor, bone morphogenetic protein-15 (BMP-15), is one such molecule. At present, nothing is known about the target cells and biological functions of BMP-15. To fill this gap in our knowledge, recombinant BMP-15 and its antibody were produced and used to determine BMP-15 expression and bioactivity. BMP-15 mRNA and protein were shown to be co-expressed in oocytes throughout folliculogenesis, supporting the idea that BMP-15 is a physiological regulator of follicle cell proliferation and/or differentiation. To test this, we used primary cultures of rat granulosa cells (GCs). We found that BMP-15 is a potent stimulator of GC proliferation, and importantly, the mitogenic effect was follicle-stimulating hormone (FSH)-independent. By contrast, BMP-15 alone had no effect on steroidogenesis. However, it produced a marked decrease in FSH-induced progesterone production, but had no effect on FSH-stimulated estradiol production. This result indicates that BMP-15 is a selective modulator of FSH action. In summary, this study identifies GCs as the first target cells for BMP-15. Moreover, it identifies the stimulation of GC proliferation and the differential regulation of two crucial steroid hormones as the first biological functions of BMP-15. Significantly, BMP-15 is the first growth factor that can coordinate GC proliferation and differentiation in a way that reflects normal physiology.  (+info)

Comparison of recombinant growth differentiation factor-9 and oocyte regulation of KIT ligand messenger ribonucleic acid expression in mouse ovarian follicles. (6/115)

Oocytes secrete factors that regulate the development of the surrounding granulosa cells in ovarian follicles. KIT ligand (KL) mRNA expression in granulosa cells is thought to be regulated by oocytes; however, the factor(s) that mediate this effect are not known. One candidate is the oocyte-specific gene product growth differentiation factor-9 (GDF-9). This study examined the effect of recombinant GDF-9 (rGDF-9) on steady-state KL mRNA expression levels in preantral and mural granulosa cells in vitro. Furthermore, the study compared the effect of rGDF-9 with that of coculture with oocytes at different developmental stages. As determined by RNase protection assay, both KL-1 and KL-2 mRNA levels in preantral and mural granulosa cells were suppressed by 25-250 ng/ml rGDF-9. Fully grown oocytes also suppressed both KL-1 and KL-2 mRNA expression levels. Partly grown oocytes isolated from 7-, 10-, or 12-day-old mice either had no effect on KL mRNA levels or promoted KL-1 mRNA steady-state expression. It is concluded that GDF-9 is likely to mediate the action of fully grown, but not partly grown, oocytes on granulosa cell KL mRNA expression.  (+info)

Bone morphogenetic protein-15 inhibits follicle-stimulating hormone (FSH) action by suppressing FSH receptor expression. (7/115)

We have recently reported that oocyte-derived bone morphogenetic protein-15 (BMP-15) can directly modulate follicle-stimulating hormone (FSH) action in rat granulosa cells. Here, we investigate underlying mechanisms of this BMP-15 effect. Treatment with BMP-15 alone exerted no significant effect on the basal expression of mRNAs encoding steroidogenic acute regulatory protein, P450 side chain cleavage enzyme, P450 aromatase, 3beta-hydroxysteroid dehydrogenase, luteinization hormone receptor, and inhibin/activin subunits. However, BMP-15 markedly inhibited the FSH-induced increases in these messages. In striking contrast, BMP-15 did not change the forskolin-induced levels of these transcripts. Thus, the inhibitory effect of BMP-15 on FSH action must be upstream of cAMP signaling. We next examined changes in FSH receptor mRNA expression. Interestingly, BMP-15 severely reduced the levels of FSH receptor mRNA in both basal and FSH-stimulated cells. To determine whether this effect was at the level of FSH function, we investigated the effect of BMP-15 on FSH bioactivity. Consistent with the mRNA data, BMP-15 inhibited the biological response of FSH, but not that of forskolin. Based on these results, we propose that BMP-15 is an important determinant of FSH action through its ability to inhibit FSH receptor expression. Because FSH plays an essential role in follicle growth and development, our findings could have new implications for understanding how oocyte growth factors contribute to folliculogenesis.  (+info)

Biological function and cellular mechanism of bone morphogenetic protein-6 in the ovary. (8/115)

The process of ovarian folliculogenesis is composed of proliferation and differentiation of the constitutive cells in developing follicles. Growth factors emitted by oocytes integrate and promote this process. Growth differentiation factor-9 (GDF-9), bone morphogenetic protein (BMP)-15, and BMP-6 are oocyte-derived members of the transforming growth factor-beta superfamily. In contrast to the recent studies on GDF-9 and BMP-15, nothing is known about the biological function of BMP-6 in the ovary. Here we show that, unlike BMP-15 and GDF-9, BMP-6 lacks mitogenic activity on rat granulosa cells (GCs) and produces a marked decrease in follicle-stimulating hormone (FSH)-induced progesterone (P(4)) but not estradiol (E(2)) production, demonstrating not only the first identification of GCs as BMP-6 targets in the ovary but also its selective modulation of FSH action in steroidogenesis. This BMP-6 activity resembles BMP-15 but differs from GDF-9 activities. BMP-6 also exhibited similar action to BMP-15 by attenuating the steady state mRNA levels of FSH-induced steroidogenic acute regulatory protein (StAR) and P450 side-chain cleavage enzyme (P450scc), without affecting P450 aromatase mRNA level, supporting its differential function on FSH-regulated P(4) and E(2) production. However, unlike BMP-15, BMP-6 inhibited forskolin- but not 8-bromo-cAMP-induced P(4) production and StAR and P450scc mRNA expression. BMP-6 also decreased FSH- and forskolin-stimulated cAMP production, suggesting that the underlying mechanism by which BMP-6 inhibits FSH action most likely involves the down-regulation of adenylate cyclase activity. This is clearly distinct from the mechanism of BMP-15 action, which causes the suppression of basal FSH receptor (FSH-R) expression, without affecting adenylate cyclase activity. As assumed, BMP-6 did not alter basal FSH-R mRNA levels, whereas it inhibited FSH- and forskolin- but not 8-bromo-cAMP-induced FSH-R mRNA accumulation. These studies provide the first insight into the biological function of BMP-6 in the ovary and demonstrate its unique mechanism of regulating FSH action.  (+info)

Expansion of the mouse cumulus-oocyte complex (COC) is dependent on oocyte-secreted paracrine factors. Transforming growth factor beta (TGFB) superfamily molecules are prime candidates for the cumulus expansion-enabling factors (CEEFs), and we have recently determined that growth differentiation factor 9 (GDF9) alone is not the CEEF. The aim of this study was to examine oocyte paracrine factors and their signaling pathways that regulate mouse cumulus expansion. Using RT-PCR, oocytes were found to express the two activin subunits, Inhba and Inhbb, and activin A and activin B both enabled FSH-induced cumulus expansion of oocytectomized (OOX) complexes. Follistatin, an activin-binding protein, neutralized activin-induced expansion but had no effect on oocyte-induced expansion. The type I receptors for GDF9 and activin are activin receptor-like kinase 5 (ALK5) and ALK4, respectively, both of which activate the same SMAD 2/3 signaling pathway. We examined the requirement for this signaling system ...
Mol Hum Reprod. 2014 Jan 26. [Epub ahead of print] Chang HM, Cheng JC, Taylor E, Leung PC. Author information Abstract In the ovary, connexin-coupled gap junctions in granulosa cells play crucial roles in follicular and oocyte development as well as in corpus luteum formation. Our previous work has shown that theca cell-derived bone morphogenetic protein (BMP)4 and BMP7 decrease gap junction intercellular communication (GJIC) activity via the down-regulation of connexin43 (Cx43) expression in immortalized human granulosa cells. However, the effects of oocyte-derived growth factors on Cx43 expression remain to be elucidated. The present study was designed to investigate the effects of oocyte-derived growth differentiation factor (GDF)9 and BMP15 on the expression of Cx43 in a human granulosa cell line, SVOG. We also examined the effect relative to GJIC activity and investigated the potential mechanisms of action. In SVOG cells, treatment with BMP15 but not GDF9 significantly decreased Cx43 mRNA ...
Growth differentiation factor-15 (GDF-15) is a member of the TGF-β cytokine superfamily that is widely expressed and may be induced in response to tissue injury. Elevations in GDF-15 may identify a novel pathway involved in loss of kidney function among patients with CKD. Among participants in the Clinical Phenotyping and Resource Biobank (C-PROBE) study and the Seattle Kidney Study (SKS), we tested whether kidney tissue expression of GDF15 mRNA correlates with circulating levels of GDF-15 and whether elevations in circulating GDF-15 are associated with decline in kidney function. In matching samples of 24 patients with CKD from the C-PROBE study, circulating GDF-15 levels significantly correlated with intrarenal GDF15 transcript levels (r=0.54, P=0.01). Among the 224 C-PROBE and 297 SKS participants, 72 (32.1%) and 94 (32.0%) patients, respectively, reached a composite end point of 30% decline in eGFR or progression to ESRD over a median of 1.8 and 2.0 years of follow up, respectively.

Aims: Growth differentiation factor 15 (GDF15) is induced during heart failure development, and may influence different processes in cardiac remodeling. While its anti-apoptotic action under conditions of ischemia-reperfusion have been shown, it remained unclear if this is a broadly protective effect applicable to other apoptotic stimuli. Furthermore, effects on cardiac hypertrophy remained obscure. Therefore, in the present study we investigated the effects of GDF15 on induction of hypertrophy and apoptosis in ventricular cardiomyocytes.. Methods and Results: Dose-response analysis of SMAD-binding affinity under stimulation with GDF15 revealed a maximal activation of SMADs, as the classical transcription factors in GDF15 signaling, by addition of 3 ng/ml GDF15 to cardiomyocytes. Under these conditions enhancement of SMAD1,5,8 phosphorylation, as another parameter of SMAD activation, was seen. At the same concentration, GDF15 enhanced hypertrophic growth as determined by an increase in cell size ...

Oocytes are powerful local modulators of follicular cell functions and many of the activities of oocytes are attributed to members of the transforming growth factor-β (TGF-β) superfamily. Whilst in the mouse it is known that members of this family are able to mimic many of the effects of oocytes on follicular cells, the relative importance of any of these factors is unknown in bovine follicles. The objectives of this study were to determine if bovine oocytes express and secrete TGF-β and to compare oocyte-secreted factor(s) to TGF-β in terms of their capacities to stimulate mural granulosa cell (MGC) DNA synthesis. Bovine ovaries were collected from an abattoir and RNA was extracted from isolated MGC, cumulus cells, cumulus-oocyte complexes and denuded oocytes (DO). Using RT-PCR, all cell types were found to express TGF-β1 and TGF-β2 mRNA transcripts. However, no TGF-β bioactivity could be detected from DO using a sensitive (40 pg/ml) and specific mink lung fibroblast cell bioassay. MGC ...

Growth differentiation factor 15 (GDF15) is a secreted protein with pleotropic functions from the transforming growth factor β (TGF-β) family. GDF15 is synthesized as a precursor and undergoes proteolytic cleavage to generate mature GDF15. The strong appetite-suppressing effect of mature GDF15 makes it an attractive therapeutic agent/target for diseases such as obesity and cachexia. In addition, clinical studies indicate that circulating, mature GDF15 is an independent biomarker for heart failure. We recently found that GDF15 functions as a heart-derived hormone that inhibits liver growth hormone signaling and postnatal body growth in the pediatric period. However, little is known about the mechanism of GDF15 maturation, in particular the enzymes that mediate GDF15 precursor cleavage. We investigated which candidate proteases can cleave GDF15 precursor and generate mature GDF15 in cardiomyocytes in vitro and mouse hearts in vivo. We discovered that three members of the proprotein convertase, ...

Serum TGF-β and GDF-15 levels in patients with CTD-ILD and CTD without ILD were significantly higher than healthy controls (respectively, 3.05±0.26, 3.05±0.22, 1.39±0.33 pg/ml, p,0.001 for TGF-β and 1.17±0.17, 1.12±0.05, 0.95±0.21 pg/ml, p,0.001 for GDF-15). There were no statistically different from patients with ILD and without ILD for both TGF-β (p:0.864) and GDF-15 levels (p:0.146) in CTD. Also, GDF-15 and TGF-β levels of patients with systemic sclerosis were not different from other CTDs. ...

Growth differentiation factor 15 (GDF-15), a marker of inflammation and oxidative stress, has emerged as a biomarker for arterial cardiovascular disease. However, the association between GDF-15 and venous thromboembolism (VTE) remains uncertain. We therefore investigated the association between plasma GDF-15 levels and future risk of incident VTE, and explored the potential of a causal association using Mendelian randomization (MR). We conducted a population-based nested case-control study comprising 416 VTE patients and 848 age- and sex-matched controls derived from the Tromsø Study. Logistic regression was used to calculate odds ratios (ORs) for VTE across GDF-15 quartiles. For the MR, we used data from the International Network on Venous Thrombosis (INVENT) consortium to examine whether single nucleotide polymorphisms (SNPs) associated with GDF-15 levels with genome-wide significance were related to VTE. We found that the ORs for VTE increased across GDF-15 quartiles (P for trend=0.002). ...
Growth differentiation factors (GDFs) are a subfamily of proteins belonging to the transforming growth factor beta superfamily that have functions predominantly in development. Several members of this subfamily have been described, and named GDF1 through GDF15. GDF1 is expressed chiefly in the nervous system and functions in left-right patterning and mesoderm induction during embryonic development. GDF2 (also known as BMP9) induces and maintains the response embryonic basal forebrain cholinergic neurons (BFCN) have to a neurotransmitter called acetylcholine, and regulates iron metabolism by increasing levels of a protein called hepcidin. GDF3 is also known as Vg-related gene 2 (Vgr-2). Expression of GDF3 occurs in ossifying bone during embryonic development and in the thymus, spleen, bone marrow brain, and adipose tissue of adults. It has a dual nature of function; it both inhibits and induces early stages of development in embryos. GDF5 is expressed in the developing central nervous system, ...

Inflammatory cell recruitment to injured tissues is needed for repair, but an excessive inflammatory response can exacerbate injury. Tibor Kempf et al. now identify the cytokine GDF-15 as a new anti-inflammatory factor that dampens leukocyte recruitment in the setting of myocardial infarction in mice, thereby preventing cardiac rupture. GDF-15 blocks leukocyte extravasation from the blood into injured tissue by inhibiting the activation of cell surface integrin receptors. Inflammatory cell recruitment after myocardial infarction needs to be tightly controlled to permit infarct healing while avoiding fatal complications such as cardiac rupture. Growth differentiation factor-15 (GDF-15), a transforming growth factor-β (TGF-β)-related cytokine, is induced in the infarcted heart of mice and humans. We show that coronary artery ligation in Gdf15-deficient mice led to enhanced recruitment of polymorphonuclear leukocytes (PMNs) into the infarcted myocardium and an increased incidence of cardiac rupture.

Results The levels of plasma GDF11 in the COPD group were decreased compared with the control groups in the two independent cohorts. The levels of plasma GDF11 were significantly positively correlated with pulmonary function data. The mRNA expression of GDF11 in mesenchymal cells from the COPD group was decreased. Chronic exposure to CSE decreased the production of GDF11. Treatment with GDF11 significantly inhibited CSE-induced cellular senescence and upregulation of inflammatory mediators, partly through Smad2/3 signalling in vitro. Daily GDF11 treatment attenuated cellular senescence and airspace enlargement in an elastase-induced mouse model of emphysema. ...

Myostatin (also known as growth differentiation factor 8, abbreviated GDF-8) is a myokine. A myokine is a protein produced and released by myocytes that acts on the autocrine function of muscle cells to inhibit myogenesis: muscle cell growth and differentiation. In humans it is encoded by the MSTN gene. Myostatin is a secreted growth differentiation factor that is a member of the TGF beta protein family. Myostatin also inhibits Akt, a kinase that causes muscle hypertrophy, in part through the activation of protein synthesis. Further research into myostatin and the myostatin gene may lead to therapies for muscular dystrophy.. *This description is meant for informational purposes only and is publicly available. ...
The objective of the present study was to examine the effects of neonatal exposure to either agonists or antagonists of androgen and estrogen receptors on the expression of growth and differentiation factor 9 (GDF9) and bone morphogenetic protein 15 (BMP15) and their cognate receptors (TGFBR1, BMPR1B, and BMPR2) in ovarian follicles of adult pigs. Piglets were injected subcutaneously with testosterone propionate (TP, an androgen, at 20 mg/kg bw), flutamide (FLU, an antiandrogen, at 50 mg/kg bw), 4-tert-octylphenol (OP, an estrogenic compound, 100 mg/kg bw), ICI 182,780 (ICI, an antiestrogen, 400 μg/kg bw), or corn oil (control) between postnatal Days 1 and 10 (n = 5/group). Ovarian follicles were excised from adult pigs on Days 8-11 of the estrous cycle. The expression of GDF9, BMP15, TGFBR1, BMPR1B and BMPR2 were examined in the population of preantral and small antral ovarian follicles using real-time PCR, Western blot and immunohistochemistry. In preantral follicles, the upregulation of GDF9 mRNA

Objective-The assembly of a functional vascular system requires a coordinated and dynamic transition from activation to maturation. High vascular endothelial growth factor activity promotes activation, including junction destabilization and cell motility. Maturation involves junctional stabilization and formation of a functional endothelial barrier. The identity and mechanism of action of prostabilization signals are still mostly unknown. Bone morphogenetic protein receptors and their ligands have important functions during embryonic vessel assembly and maturation. Previous work has suggested a role for growth differentiation factor 6 (GDF6; bone morphogenetic protein 13) in vascular integrity although GDF6s mechanism of action was not clear. Therefore, we sought to further explore the requirement for GDF6 in vascular stabilization. ...
Oocyte control of granulosa and theca cell function may be mediated by several growth factors via a local feedback loop(s) between these cell types. This study examined both the role of oocyte-secreted factors on granulosa and thecal cells, cultured independently and in co-culture, and the effect of stem cell factor (SCF); a granulosa cell derived peptide that appears to have multiple roles in follicle development. Granulosa and theca cells were isolated from 2-6 mm healthy follicles of mature porcine ovaries and cultured under serum-free conditions, supplemented with: 100 ng/ml LR3 IGF-1, 10 ng/ml insulin, 100 ng/ml testosterone, 0-10 ng/ml SCF, 1 ng/ml FSH (granulosa), 0.01 ng/ml LH (theca) or 1 ng/ml FSH and 0.01 ng/ml LH (co-culture) and with/without oocyte conditioned medium (OCM) or 5 oocytes. Cells were cultured in 96 well plates for 144 h, after which viable cell numbers were determined. Medium was replaced every 48 h and spent medium analysed for steroids.Oocyte secreted factors were ...
Daniel A. Dumesic, M.D., JoAnne S. Richards, Ph.D.. Volume 100, Issue 1, Pages 23-38, July 2013. Abstract:. Activation of primordial follicles into the growing pool, selection of the dominant follicle and its eventual ovulation require complex endocrine and metabolic interactions, as well as intraovarian paracrine signals to coordinate granulosa cell proliferation, theca cell differentiation and oocyte maturation. Early preantral follicle development relies mostly upon mesenchymal-epithelial cell interactions, intraovarian paracrine signals and oocyte-secreted factors, while development of the antral follicle depends upon circulating gonadotropins as well as locally-derived regulators. In women with polycystic ovary syndrome (PCOS), ovarian hyperandrogenism, hyperinsulinemia from insulin resistance and altered intrafollicular paracrine signaling perturb activation, survival, growth and selection of follicles, causing accumulation of small antral follicles within the periphery of the ovary, ...
Certain microRNAs (miRs) have important roles in the maintenance of bone development and metabolism, and a variety of miRs are known to be deregulated in diabetes. The present study investigated the role of miR‑203‑3p in the regulation of bone loss by assessing jaw bones of a rat model of type 2 diabetes. The results indicated that miR‑203‑3p inhibited osteogenesis in the jaws of diabetic rats and in rat bone marrow mesenchymal stem cells cultured in high‑glucose medium. A luciferase re-porter assay was used to verify the bioinformatics prediction that miR‑203‑3p targets the 3‑untranslated region of Smad1, which is an important mediator of the bone morphogenetic protein (BMP)/Smad pathway ...
The fact that a mutation in Alk5 had an effect in the Acvr2b‐null background indicates that Alk5 must also be coupling to another type II receptor, most probably Acvr2, to mediate the effects of GDF11 on embryonic development. In support of this idea, mutations in Acvr2 have been shown to augment the phenotypes observed in Acvr2b−/− animals (Oh et al, 2002). Unlike Acvr2b−/− mutants, however, Acvr2−/− animals lack any vertebral patterning defects, indicating that although the Acvr2b−/− strain is genetically sensitized for those phenotypes, the Acvr2−/− strain is not. Together with the absence of effects of ALK4 and ALK7 in axial patterning, the lack of ALK4 and ALK7 expression in relevant patterning structures and the fact that GDF11, similar to TGF‐β, signals through Smad2 and Smad3, our results strongly indicate that GDF11 uses the TGF‐β receptor ALK5 in vivo to control several developmental events. Our study has not addressed the possible participation of other ...
As it is known that the normal tumor microenvironment becomes corrupted during tumor development, which is reflected by appearance of a large and heterogeneous category of cancer-associated fibroblasts (CAFs) [28]. CAF cells are considered active modulators of the tumor microenvironment among many solid tumors [29-31]. However, few studies have directly addressed the role of the CAFs in the BM of leukemia. In the present study, we demonstrate that functional CAFs are widespread in the BM of AML patients and could serve as a critical chemo-protective element for AML cells by producing an abundance of GDF15.. As we all know, AML cells interact both anatomically and functionally with the stroma within the BM microenvironment. These interactions have a critical role in the development, progression and relapse of AML. A recent study has suggested discoidin domain receptor 1 (DDR1), a class of collagen-activated receptor tyrosine kinase (RTK) was highly upregulated on bone marrow (BM)-derived CD33+ ...

21] The board observes that such a dichotomy arose between, on the one hand, the disclosure in the patent application underlying decision T 1329/04 (lack of the seven cystein residues with their peculiar spacing required for a protein (in that case, GDF-9) to belong to the TGF-beta superfamily - see T 1329/04 [7] - and the lack of functional characterisation of GDF-9 - see ibidem, [9]) and, on the other hand, the teaching in post-published document D4 that GDF-9 was indeed a growth differentiation factor (see T 1329/04 [12]). Hence, the then competent board concluded that there was not enough evidence in the application as filed to make it at least plausible that a solution had been found to the problem alleged to be solved ...

  • Several factors regulating the proliferation and differentiation of GCs have been reported, most of which belong to the transforming growth factor superfamily, for instance the group of bone morphogenetic proteins (BMPs) ( 7 - 9 ). (
  • rhBMP-2 is much more widely used clinically because it helps grow bone better than rhBMP-7 and other BMPs. (
  • Although the name BMP describes the ability of BMPs to induce ectopic bone or cartilage formation, it is misleading in that BMPs are critical in development of the viscera and have roles in cell proliferation, apoptosis, differerntiation, and morphogenesis. (
  • Bone morphogenetic proteins (BMPs) are the members of the TGF-β superfamily and are identified as the critical factors for formation of bone and cartilage, hematopoietic cell formation and mesoderm patterning. (
  • BMPs bind to BMP R2 and then recruits the transducing type I receptor which in turn activate the Smad protein signaling pathway. (
  • Discussion at a meeting in Berlin, Germany, showed that BMPs have essential functions in organs and tissues besides bone. (
  • Human embryonic stem cells (hESC) can be induced to differentiate to trophoblast by bone morphogenetic proteins (BMPs) and by aggregation to form embryoid bodies (EB), but there are many differences and controversies regarding the nature of the differentiated cells. (
  • Named KCP, for kielin/chordin-like protein, the new protein is the first of its kind found to directly enhance signals from bone morphogenetic proteins or BMPs, which are vital to the normal development and healthy functioning of the kidney. (
  • PMID26113727}} "Bone morphogenetic proteins (BMPs) act in dose-dependent fashion to regulate cell fate choices in a myriad of developmental contexts. (
  • Bone Morphogenetic Proteins (BMPs) play crucial roles in a variety of developmental processes, but their functions during early vertebrate brain development are largely unknown. (
  • Bone morphogenetic proteins (BMPs) belong to the transforming growth factor superfamily and have been implicated in chondrogenesis and neuronal differentiation. (
  • BMPs were originally identified as protein regulators of cartilage and bone formation. (
  • Similar to other TGF-beta family proteins, BMPs are highly conserved across animal species. (
  • Effect of Bone Morphogenetic Protein-2 (BMP-2) on Matrix Production, Other BMPs, and BMP Receptors in Rat Intervertebral Disc Cells. (
  • Members of the TGF-β superfamily with important effects on bone cell differentiation are bone morphogenetic proteins (BMPs) ( 17 , 41 ), which were first identified as factors that induce bone formation in vivo when implanted into muscular tissues ( 54 ). (
  • Unlike TGF-β, which induces new bone formation only when injected near bone, BMPs produce bone formation even when injected into ectopic sites. (
  • Bone morphogenetic proteins (BMPs) play an important role in neuronal differentiation and morphogenesis, and BMP7 in particular induces the formation of dendrites. (
  • Bone morphogenetic proteins (BMPs) represent a large subgroup of the transforming growth factor (TGF)-β superfamily. (
  • BMP-15 and GDF9 interact with each other and work synergistically to have similar interactions with the target cell. (
  • Bone morphogenetic protein 15 (BMP15) and growth and differentiation factor 9 (GDF9) play critical roles in folliculogenesis, follicular development and ovulation in mammalian ovaries. (
  • 100 µg) The precise function of BMP15 is still unknown, but it seems to be involved in oocyte maturation and follicular development as a homodimer or by forming heterodimers with a related protein, GDF9. (
  • Among the growth factors, the growth differentiation factor 9 (GDF9) and the bone morphogenetic protein 15 (BMP15), belong to the transforming growth factor beta (TGF-β) superfamily, have been implicated as essential for follicular development. (
  • The GDF9 and BMP15 participate in the evolution of the primordial follicle to primary follicle and play an important role in the later stages of follicular development and maturation, increasing the steroidogenic acute regulatory protein expression, plasminogen activator and luteinizing hormone receptor (LHR). (
  • Among the factors secreted by the oocyte, we highlight members of the transforming growth factor beta (TGF-β) superfamily and, among these, the growth and differentiation factor 9 (GDF9) and bone morphogenetic protein 15 (BMP15), which are expressed in all stages of follicular development in the bovine species and are involved in controlling the proliferation and steroidogenesis of granulosa cells ( Juengel and McNatty, 2005 ). (
  • Genes from the ovarian bone morphogenetic signaling pathway (GDF9 and BMP15) are critical for normal human fertility. (
  • It is thought that this protein may be involved in oocyte maturation and follicular development as a homodimer or by forming heterodimers with a related protein, Gdf9. (
  • New naturally occurring mutations in genes for the oocyte-derived growth factors growth differentiation factor 9 (GDF9) and bone morphogenetic protein 15 (BMP15) are described. (
  • Two genes in this pathway are growth differentiation factor 9 GDF9 on chromosome 5 and bone morphogenetic protein 15 Ccab on the X chromosome. (
  • [3] However, BMPR2 can't bind BMP15 and GDF9 without the assistance of bone morphogenetic protein receptor 1B (BMPR1B) and transforming growth factor β receptor 1 (TGFβR1) respectively. (
  • Another TGF-β superfamily cytokine linked recently to epithelial malignancies is MIC-1, which is also known by other names including prostate-derived factor, growth differentiation factor-15, placental bone morphogenetic protein (PLAB), placental transforming growth factor β, and nonsteroidal anti-inflammatory drug-activated protein 1. (
  • NAG-1 is also known as Macrophage Inhibitory Cytokine-1 (MIC-1), Growth Differentiation Factor 15 (GDF15), Placental Bone Morphogenetic Protein (PLAB), or Prostate Derived Factor (PDF). (
  • BMP-15 is released from the oocyte into the surrounding granulosa tissue where it binds to two membrane bound receptors on granulosa cells. (
  • These results are the first to demonstrate that oocyte-secreted factors, and particularly BMP15 and BMP6, maintain the low incidence of cumulus cell apoptosis by establishing a localized gradient of bone morphogenetic proteins. (
  • A gene on chromosome Xp11.2 that encodes bone morphogenetic protein 15, which is thought to play a role in oocyte and follicular development. (
