One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.

The level of protein structure in which combinations of secondary protein structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.

The surface ectoderm is essential for nephric duct formation in intermediate mesoderm. (1/1354)

The nephric duct is the first epithelial tubule to differentiate from intermediate mesoderm that is essential for all further urogenital development. In this study we identify the domain of intermediate mesoderm that gives rise to the nephric duct and demonstrate that the surface ectoderm is required for its differentiation. Removal of the surface ectoderm resulted in decreased levels of Sim-1 and Pax-2 mRNA expression in mesenchymal nephric duct progenitors, and caused inhibition of nephric duct formation and subsequent kidney development. The surface ectoderm expresses BMP-4 and we show that it is required for the maintenance of high-level BMP-4 expression in lateral plate mesoderm. Addition of a BMP-4-coated bead to embryos lacking the surface ectoderm restored normal levels of Sim-1 and Pax-2 mRNA expression in nephric duct progenitors, nephric duct formation and the initiation of nephrogenesis. Thus, BMP-4 signaling can substitute for the surface ectoderm in supporting nephric duct morphogenesis. Collectively, these data suggest that inductive interactions between the surface ectoderm, lateral mesoderm and intermediate mesoderm are essential for nephric duct formation and the initiation of urogenital development.  (+info)

Bmp4 is required for the generation of primordial germ cells in the mouse embryo. (2/1354)

In many organisms the allocation of primordial germ cells (PGCs) is determined by the inheritance of maternal factors deposited in the egg. However, in mammals, inductive cell interactions are required around gastrulation to establish the germ line. Here, we show that Bmp4 homozygous null embryos contain no PGCs. They also lack an allantois, an extraembryonic mesodermal tissue derived, like the PGCs, from precursors in the proximal epiblast. Heterozygotes have fewer PGCs than normal, due to a reduction in the size of the founding population and not to an effect on its subsequent expansion. Analysis of beta-galactosidase activity in Bmp4(lacZneo) embryos reveals that prior to gastrulation, Bmp4 is expressed in the extraembryonic ectoderm. Later, Bmp4 is expressed in the extraembryonic mesoderm, but not in PGCs. Chimera analysis indicates that it is the Bmp4 expression in the extraembryonic ectoderm that regulates the formation of allantois and primordial germ cell precursors, and the size of the founding population of PGCs. The initiation of the germ line in the mouse therefore depends on a secreted signal from the previously segregated, extraembryonic, trophectoderm lineage.  (+info)

A binding site for homeodomain and Pax proteins is necessary for L1 cell adhesion molecule gene expression by Pax-6 and bone morphogenetic proteins. (3/1354)

The cell adhesion molecule L1 regulates axonal guidance and fasciculation during development. We previously identified the regulatory region of the L1 gene and showed that it was sufficient for establishing the neural pattern of L1 expression in transgenic mice. In the present study, we characterize a DNA element within this region called the HPD that contains binding motifs for both homeodomain and Pax proteins and responds to signals from bone morphogenetic proteins (BMPs). An ATTA sequence within the core of the HPD was required for binding to the homeodomain protein Barx2 while a separate paired domain recognition motif was necessary for binding to Pax-6. In cellular transfection experiments, L1-luciferase reporter constructs containing the HPD were activated an average of 4-fold by Pax-6 in N2A cells and 5-fold by BMP-2 and BMP-4 in Ng108 cells. Both of these responses were eliminated on deletion of the HPD from L1 constructs. In transgenic mice, deletion of the HPD from an L1-lacZ reporter resulted in a loss of beta-galactosidase expression in the telencephalon and mesencephalon. Collectively, our experiments indicate that the HPD regulates L1 expression in neural tissues via homeodomain and Pax proteins and is likely to be a target of BMP signaling during development.  (+info)

Ectopic bone morphogenetic proteins 5 and 4 in the chicken forebrain lead to cyclopia and holoprosencephaly. (4/1354)

Proper dorsal-ventral patterning in the developing central nervous system requires signals from both the dorsal and ventral portions of the neural tube. Data from multiple studies have demonstrated that bone morphogenetic proteins (BMPs) and Sonic hedgehog protein are secreted factors that regulate dorsal and ventral specification, respectively, within the caudal neural tube. In the developing rostral central nervous system Sonic hedgehog protein also participates in ventral regionalization; however, the roles of BMPs in the developing brain are less clear. We hypothesized that BMPs also play a role in dorsal specification of the vertebrate forebrain. To test our hypothesis we implanted beads soaked in recombinant BMP5 or BMP4 into the neural tube of the chicken forebrain. Experimental embryos showed a loss of the basal telencephalon that resulted in holoprosencephaly (a single cerebral hemisphere), cyclopia (a single midline eye), and loss of ventral midline structures. In situ hybridization using a panel of probes to genes expressed in the dorsal and ventral forebrain revealed the loss of ventral markers with the maintenance of dorsal markers. Furthermore, we found that the loss of the basal telencephalon was the result of excessive cell death and not a change in cell fates. These data provide evidence that BMP signaling participates in dorsal-ventral patterning of the developing brain in vivo, and disturbances in dorsal-ventral signaling result in specific malformations of the forebrain.  (+info)

A BMP-inducible gene, dlx5, regulates osteoblast differentiation and mesoderm induction. (5/1354)

Bone morphogenetic proteins (BMPs), members of the transforming growth factor beta superfamily, have been identified by their ability to induce cartilage and bone from nonskeletal cells and have been shown to act as a ventral morphogen in Xenopus mesoderm. We isolated a murine homeobox-containing gene, distal-less 5 (mDlx5), as a BMP-inducible gene in osteoblastic MC3T3-E1 cells. Stable transfectants of MC3T3-E1 that overexpress mDlx5 mRNA showed increase in various osteogenic markers, a fourfold increase in alkaline phosphatase activity, a sixfold increase in osteocalcin production, and appearance in mineralization of extracellular matrix. Furthermore, mDlx5 was induced orthotopically in mouse embryos treated with BMP-4 and in fractured bone of adult mice. Consistent with these observations, we also found that injection of mDlx5 mRNA into dorsal blastomeres enhanced the ventralization of Xenopus embryos. These findings suggest that mDlx5 is a target gene of the BMP signaling pathway and acts as an important regulator of both osteogenesis and dorsoventral patterning of embryonic axis.  (+info)

Bone morphogenetic proteins regulate the developmental program of human hematopoietic stem cells. (6/1354)

The identification of molecules that regulate human hematopoietic stem cells has focused mainly on cytokines, of which very few are known to act directly on stem cells. Recent studies in lower organisms and the mouse have suggested that bone morphogenetic proteins (BMPs) may play a critical role in the specification of hematopoietic tissue from the mesodermal germ layer. Here we report that BMPs regulate the proliferation and differentiation of highly purified primitive human hematopoietic cells from adult and neonatal sources. Populations of rare CD34(+)CD38(-)Lin- stem cells were isolated from human hematopoietic tissue and were found to express the BMP type I receptors activin-like kinase (ALK)-3 and ALK-6, and their downstream transducers SMAD-1, -4, and -5. Treatment of isolated stem cell populations with soluble BMP-2, -4, and -7 induced dose-dependent changes in proliferation, clonogenicity, cell surface phenotype, and multilineage repopulation capacity after transplantation in nonobese diabetic/severe combined immunodeficient (NOD/SCID) mice. Similar to transforming growth factor beta, treatment of purified cells with BMP-2 or -7 at high concentrations inhibited proliferation yet maintained the primitive CD34(+)CD38(-) phenotype and repopulation capacity. In contrast, low concentrations of BMP-4 induced proliferation and differentiation of CD34(+) CD38(-)Lin- cells, whereas at higher concentrations BMP-4 extended the length of time that repopulation capacity could be maintained in ex vivo culture, indicating a direct effect on stem cell survival. The discovery that BMPs are capable of regulating repopulating cells provides a new pathway for controlling human stem cell development and a powerful model system for studying the biological mechanism of BMP action using primary human cells.  (+info)

Opposite effects of FGF and BMP-4 on embryonic blood formation: roles of PV.1 and GATA-2. (7/1354)

In adult vertebrates, fibroblast growth factor (FGF) synergizes with many hematopoietic cytokines to stimulate the proliferation of hematopoietic progenitors. In vertebrate development, the FGF signaling pathway is important in the formation of some derivatives of ventroposterior mesoderm. However, the function of FGF in the specification of the embryonic erythropoietic lineage has remained unclear. Here we address the role of FGF in the specification of the erythropoietic lineage in the Xenopus embryo. We report that ventral injection of embryonic FGF (eFGF) mRNA at as little as 10 pg at the four-cell stage suppresses ventral blood island (VBI) formation, whereas expression of the dominant negative form of the FGF receptor in the lateral mesoderm, where physiologically no blood tissue is formed, results in a dramatic expansion of the VBI. Similar results were observed in isolated ventral marginal zones and animal caps. Bone morphogenetic protein-4 (BMP-4) is known to induce erythropoiesis in the Xenopus embryo. Therefore, we examined how the BMP-4 and FGF signaling pathways might interact in the decision of ventral mesoderm to form blood. We observed that eFGF inhibits BMP-4-induced erythropoiesis by differentially regulating expression of the BMP-4 downstream effectors GATA-2 and PV.1. GATA-2, which stimulates erythropoiesis, is suppressed by FGF. PV.1, which we demonstrate to inhibit blood development, is enhanced by FGF. Additionally, PV.1 and GATA-2 negatively regulate transcription of each other. Thus, BMP-4 induces two transcription factors which have opposing effects on blood development. The FGF and BMP-4 signaling pathways interact to regulate the specification of the erythropoietic lineage.  (+info)

The smad5 mutation somitabun blocks Bmp2b signaling during early dorsoventral patterning of the zebrafish embryo. (8/1354)

Signaling by members of the TGFbeta superfamily is thought to be transduced by Smad proteins. Here, we describe a zebrafish mutant in smad5, designated somitabun (sbn). The dominant maternal and zygotic effect of the sbntc24 mutation is caused by a change in a single amino acid in the L3 loop of Smad5 protein which transforms Smad5 into an antimorphic version, inhibiting wild-type Smad5 and related Smad proteins. sbn mutant embryos are strongly dorsalized, similarly to mutants in Bmp2b, its putative upstream signal. Double mutant analyses and RNA injection experiments show that sbn and bmp2b interact and that sbn acts downstream of Bmp2b signaling to mediate Bmp2b autoregulation during early dorsoventral (D-V) pattern formation. Comparison of early marker gene expression patterns, chimera analyses and rescue experiments involving temporally controlled misexpression of bmp or smad in mutant embryos reveal three phases of D-V patterning: an early sbn- and bmp2b-independent phase when a coarse initial D-V pattern is set up, an intermediate sbn- and bmp2b-dependent phase during which the putative morphogenetic Bmp2/4 gradient is established, and a later sbn-independent phase during gastrulation when the Bmp2/4 gradient is interpreted and cell fates are specified.  (+info)

The molecular factors that regulate cardiac differentiation have been extensively studied, yet, relatively little is known about how cardiomyocytes acquire atrial versus ventricular characteristics. Embryonic stem (ES) cells, which have the potential to differentiate to a wide array of distinct cell types, including most types of cardiovascular cells, offer a pertinent in vitro model to work out the molecular mechanisms of atrial specification and differentiation. We discovered that the secreted antagonist of BMP signaling, Protein Related to Dan and Cerberus (PRDC, also called Gremlin2) leads to a surge in cardiomyocytic differentiation when applied to mouse ES-derived cardiac progenitor cells. This property is unique to PRDC among tested BMP antagonists. Lineage expansion is restricted to cardiomyocytes, with the differentiation of endodermal, blood, endothelial and neuronal cells being unaffected. Using molecular and electrophysiological analyses, we show that PRDC-induced cardiomyocytes ...

Noggin protein is a potent bone morphogenetic protein (BMP) antagonist capable of inhibiting vasculogenesis even in the presence of provasculogenic VEGF and FGF-2. We found that human umbilical vein endothelial cells (HUVECs) do not express Noggin in culture and used these cells for modeling of antivasculogenesis. We hypothesized that high-efficiency transduction of HUVECs with bicistronic lentiviral vector encoding Noggin and enhanced green fluorescent protein (EGFP) enables direct visualization of Noggin effects in homogenous primary cell populations in vitro and in vivo. By comparing HUVECs transduced with a control GFP and GFP/Noggin expression cassettes, we showed that constitutive and orthotopic Noggin protein expression did not influence cell proliferation, down-regulated BMP-2 expression, and showed no effect on BMP receptor transcripts. We demonstrated that in contrast to GFP-only control, Noggin expression in endothelial cells abrogated endothelial migration in response to monolayer injury,

Several models have been proposed to explain the anti- and pro-Bmp mechanisms of Bmper (Coles et al., 2004). Recently, a paper using biochemical and genetic studies in Drosophila proposes a model where Cv-2 can enhance and inhibit Bmp signaling at low and high concentrations, respectively (Serpe et al., 2008). Dependency on concentration and proteolytic cleavage have also been reported for other extracellular modulators of Bmp activity (Larrain et al., 2001). Our data provide an additional mechanism whereby proteolysis and concentration dependency fine-tune Bmp signaling through interactions with secreted proteins.. Although both proteolytic activation and inactivation have been described for several Bmp factors, the degradation of secreted Bmps are incompletely understood. To date, limited data are available describing Bmp degradation (Entchev et al., 2000; Degnin et al., 2004). Lysosomal- and proteasomal-dependent degradation of Bmp4 within the presecretory pathway was shown to occur after the ...

Objective: Pancreas organogenesis is orchestrated by interactions between the epithelium and the mesenchyme, but these interactions are incompletely understood. Here we investigated a role for BMP signalling within the pancreas mesenchyme and found it to be required for the normal development of the mesenchyme as well as the pancreatic epithelium.. Research Design and Methods: We analysed active BMP signalling by immunostaining for phospho-Smad1,5,8 and tested whether pancreas development was affected by BMP inhibition after expression of Noggin and dominant negative BMP receptors in chicken and mouse pancreas.. Results: Endogenous BMP signalling is confined to the mesenchyme in the early pancreas and inhibition of BMP signalling results in severe pancreatic hypoplasia with reduced epithelial branching. Notably, we also observe an excessive endocrine differentiation when mesenchymal BMP signalling is blocked, presumably secondary to defective mesenchyme to epithelium signalling.. Conclusions: We ...

The first evident break in left-right symmetry of the primitive zebrafish heart tube is the shift in pattern of BMP4 expression from radially symmetric to left-predominant. The midline heart tube then jogs to the left and subsequently loops to the right. We examined 279 mutations, affecting more than 200 genes, and found 21 mutations that perturb this process. Some cause BMP4 to remain radially symmetric. Others randomize the asymmetric BMP4 pattern. Retention of BMP4 symmetry is associated with failure to jog: right-predominance of the BMP4 pattern is associated with reversal of the direction of jogging and looping. Raising BMP4 diffusely throughout the heart, via sonic hedgehog injection, or the blocking of its action by injection of a dominant negative BMP4 receptor, prevent directional jogging or looping. The genes crucial to directing cardiac asymmetry include a subset of those needed for patterning the dorsoventral axis and for notochord and ventral spinal cord development. Thus, the ...

In the present study, we explored the correlations of the BMP4 gene polymorphisms and the serum BMP4 levels with the development of LVH among Chinese EH patients. We found that the 6007C , T polymorphism of the BMP4 gene and the serum BMP4 level were significantly associated with the risk to develop LVH. Our in vitro study shows that the BMP4 inhibition in cardiomyocyte by si-RNA technique significantly decreased the Ang II induced cardiomyocyte size and protein content per cell, indicating the importance of BMP4 in the cardiomyocyte hypertrophy. Collectively, our data suggest that both the 6007C , T of the BMP4 gene and the serum BMP4 level may be used as potential marker for LVH incidence among the EH patients..

In some cases mice injected with cells transfected with industrial non distinct shRNA showed mixed responses, while these cells had been efficiently applied in vitro. Certainly, even further analysis of this RNA sequence exposed some similarity together with the RNA sequences of bone morphogenic protein two and SMAD5, the two of which are involved in TGF B signaling, which may well make clear the source of these spurious effects.

Bone morphogenetic protein 10 (BMP10) is a member of the TGF-β superfamily and plays a critical role in heart development. In the postnatal heart, BMP10 is restricted to the right atrium. The inactive pro-BMP10 (∼60 kDa) is processed into active BMP10 (∼14 kDa) by an unknown protease. Proteolytic cleavage occurs at the RIRR(316)↓ site (human), suggesting the involvement of proprotein convertase(s) (PCs). In vitro digestion of a 12-mer peptide encompassing the predicted cleavage site with furin, PACE4, PC5/6, and PC7, showed that furin cleaves the best, whereas PC7 is inactive on this peptide. Ex vivo studies in COS-1 cells, a cell line lacking PC5/6, revealed efficient processing of pro-BMP10 by endogenous PCs other than PC5/6. The lack of processing of overexpressed pro-BMP10 in the furin- and PACE4-deficient cell line, CHO-FD11, and in furin-deficient LoVo cells, was restored by stable (CHO-FD11/Fur cells) or transient (LoVo cells) expression of furin.

FK506 appears superior to rapamycin in potentiating BMP signaling because it also inhibits the phosphatase calcineurin (51). In addition, FK506 interacts with FKBP12 associated with all 3 BMPR type 1 receptors (ALK1, ALK2, and ALK3), including those preferred by BMPR2 (ALK1 and ALK3), whereas rapamycin only interacts with ALK2. Cyclosporine shares the calcineurin inhibitory properties of FK506 (52), but as it does not bind FKBP12, it is ...
Chondrogenic differentiating mesenchymal stem cells (MSCs) are mimicking embryonal endochondral ossification and become hypertrophic. BMP (bone morphogenetic protein) and Activin Membrane Bound Inhibitor (BAMBI) is a pseudoreceptor that regulates the activity of transforming growth factor-|i|β|/i| (TGF-|i|β|/i|) and BMP signalling during chondrogenesis. Both TGF-|i|β|/i| and BMP signalling are regulators of chondrogenic cell differentiation. Human bone marrow derived MSCs were chondrogenically predifferentiated in aggregate culture for 14 days. Thereafter, one group was subjected to hypertrophy enhancing media conditions while controls were kept in chondrogenic medium until day 28. Histological evaluation, gene expression by PCR, and Western blot analysis were carried out at days 1, 3, 7, 14, 17, 21, and 28. A subset of cultures was treated with the BMP inhibitor Noggin to test for BMP dependent expression of BAMBI. Hypertrophic differentiated pellets showed larger cells with increased
Research Interests: Signal Transduction Bone Morphogenetic Proteins Growth and Embryonic Development Mouse Models Xenopus laevis Proprotein Convertases Hematopoiesis Extracellular Matrix Cell-cell signaling molecules such as bone morphogenetic proteins (BMPs) play critical roles in specifying cell fate during vertebrate embryogenesis. Strict regulation of BMP activity is required to prevent birth defects, degenerative diseases and cancer. Our research program has two major foci: 1) Understanding how BMP activity is regulated by cleavage of the precursor protein and by interactions with the extracellular matrix. We use targeted mutagenesis in mice together with cell biological and biochemical approaches in Xenopus embryos to determine how cleavages within the inactive prodomain of the BMP precursor protein regulate the activity of mature BMP homodimers and heterodimers. One current project in the lab involves analysis of mice carrying a point mutation that prevents cleavage of BMP7. This cleavage ...
Rising obesity epidemic makes the better understanding of transcription factor networks regulating adipogenesis very challenging.

Das Bone Morphogenetic Protein 2 (BMP2) gehört zur TGF-beta Superfamilie und findet seinen Fokus in der osteogenen Aktivierung und in der Anwendung bei der Frakturheilung. Es wird angenommen, dass weitere, bisher unbekannte Verbindungen existieren, die die BMP2-Signalübertragung und die osteogene Aktivität verbessern und somit zu einer verbesserten klinischen Wirksamkeit von BMP2 führen. Für den Stickstoffoxid (NO)-Signalweg ist bereits bekannt, dass im endothelialen Kontext eine Verbindung zum BMP2-Signalweg existiert. Ziel dieser Arbeit war es daher, eine Verbindung zwischen dem NO- und BMP2-Signalweg bezüglich der Regulierung des BMP2-abhängigen Signalwegs und der Osteoinduktion aufzuzeigen. Dies erfolgte durch Anwendung von Inhibitoren (LNAME, ODQ und LY83583) und Aktivatoren (L-Arginin, Deta NONOate, SNAP und YC-1) des NO-Signalwegs, in Kombination mit BMP2. Eine mögliche Verbindung zwischen dem BMP2- und NO-Signalweg, über eine Protein Kinase A (PKA) Brücke, wurde durch die ...

Pediatric neuroblastoma in its advanced stage (st. IV) is usually lethal. 70% of the affected children die. 50% of the children show upon diagnosis metastasis or a genetic amplification of the oncogene N-myc. This group has a poor prognosis and a 5-year survival rate of only 33%. A drawback of the current standard therapy is the poor efficacy accompanied with severe side effects. Therefore a new treatment of neuroblastoma with a different antitumoral mode of action than the traditional cytotoxics is urgently required ...
2040 Attempts by our lab to regulate ectopic bone formation in vivo have inadvertently revealed a very important biological phenomenon: excessive expression of the BMP antagonist, Noggin, in the presence of BMP4 induces tumor formation. BMP4:Noggin co-expression at specific ratios generated a malignant mesenchyoma, a mixture of osteosarcoma, rhabdomyosarcoma and undifferentiated neoplastic cells, derived from our implanted muscle-derived stem cells (MDSCs). We believe that these cells displayed aberrant differentiation or became stuck in a mixed differentiated state and underwent oncogenesis as a result of conflicting signals attributable to concurrent Noggin and BMP4 expression. To investigate this hypothesis, we cultured populations of BMP4- and Noggin-expressing MDSCs at various ratios. When grown for 7 weeks, mixed populations cultured at ratios of 1:2 and 1:3 (BMP4-:Noggin-expressing MDSCs) formed more colonies on soft agar than did either mixed populations cultured at a ratio of 1:1 or ...
