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. (1/3840)

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)

A Drosophila doublesex-related gene, terra, is involved in somitogenesis in vertebrates. (2/3840)

The Drosophila doublesex (dsx) gene encodes a transcription factor that mediates sex determination. We describe the characterization of a novel zebrafish zinc-finger gene, terra, which contains a DNA binding domain similar to that of the Drosophila dsx gene. However, unlike dsx, terra is transiently expressed in the presomitic mesoderm and newly formed somites. Expression of terra in presomitic mesoderm is restricted to cells that lack expression of MyoD. In vivo, terra expression is reduced by hedgehog but enhanced by BMP signals. Overexpression of terra induces rapid apoptosis both in vitro and in vivo, suggesting that a tight regulation of terra expression is required during embryogenesis. Terra has both human and mouse homologs and is specifically expressed in mouse somites. Taken together, our findings suggest that terra is a highly conserved protein that plays specific roles in early somitogenesis of vertebrates.  (+info)

Requirement of a novel gene, Xin, in cardiac morphogenesis. (3/3840)

A novel gene, Xin, from chick (cXin) and mouse (mXin) embryonic hearts, may be required for cardiac morphogenesis and looping. Both cloned cDNAs have a single open reading frame, encoding proteins with 2,562 and 1,677 amino acids for cXin and mXin, respectively. The derived amino acid sequences share 46% similarity. The overall domain structures of the predicted cXin and mXin proteins, including proline-rich regions, 16 amino acid repeats, DNA-binding domains, SH3-binding motifs and nuclear localization signals, are highly conserved. Northern blot analyses detect a single message of 8.9 and 5.8 kilo base (kb) from both cardiac and skeletal muscle of chick and mouse, respectively. In situ hybridization reveals that the cXin gene is specifically expressed in cardiac progenitor cells of chick embryos as early as stage 8, prior to heart tube formation. cXin continues to be expressed in the myocardium of developing hearts. By stage 15, cXin expression is also detected in the myotomes of developing somites. Immunofluorescence microscopy reveals that the mXin protein is colocalized with N-cadherin and connexin-43 in the intercalated discs of adult mouse hearts. Incubation of stage 6 chick embryos with cXin antisense oligonucleotides results in abnormal cardiac morphogenesis and an alteration of cardiac looping. The myocardium of the affected hearts becomes thickened and tends to form multiple invaginations into the heart cavity. This abnormal cellular process may account in part for the abnormal looping. cXin expression can be induced by bone morphogenetic protein (BMP) in explants of anterior medial mesoendoderm from stage 6 chick embryos, a tissue that is normally non-cardiogenic. This induction occurs following the BMP-mediated induction of two cardiac-restricted transcription factors, Nkx2.5 and MEF2C. Furthermore, either MEF2C or Nkx2.5 can transactivate a luciferase reporter driven by the mXin promoter in mouse fibroblasts. These results suggest that Xin may participate in a BMP-Nkx2.5-MEF2C pathway to control cardiac morphogenesis and looping.  (+info)

Mechanisms of GDF-5 action during skeletal development. (4/3840)

Mutations in GDF-5, a member of the TGF-beta superfamily, result in the autosomal recessive syndromes brachypod (bp) in mice and Hunter-Thompson and Grebe-type chondrodysplasias in humans. These syndromes are all characterised by the shortening of the appendicular skeleton and loss or abnormal development of some joints. To investigate how GDF-5 controls skeletogenesis, we overexpressed GDF-5 during chick limb development using the retrovirus, RCASBP. This resulted in up to a 37.5% increase in length of the skeletal elements, which was predominantly due to an increase in the number of chondrocytes. By injecting virus at different stages of development, we show that GDF-5 can increase both the size of the early cartilage condensation and the later developing skeletal element. Using in vitro micromass cultures as a model system to study the early steps of chondrogenesis, we show that GDF-5 increases chondrogenesis in a dose-dependent manner. We did not detect changes in proliferation. However, cell suspension cultures showed that GDF-5 might act at these stages by increasing cell adhesion, a critical determinant of early chondrogenesis. In contrast, pulse labelling experiments of GDF-5-infected limbs showed that at later stages of skeletal development GDF-5 can increase proliferation of chondrocytes. Thus, here we show two mechanisms of how GDF-5 may control different stages of skeletogenesis. Finally, our data show that levels of GDF-5 expression/activity are important in controlling the size of skeletal elements and provides a possible explanation for the variation in the severity of skeletal defects resulting from mutations in GDF-5.  (+info)

Isolation of zebrafish gdf7 and comparative genetic mapping of genes belonging to the growth/differentiation factor 5, 6, 7 subgroup of the TGF-beta superfamily. (5/3840)

The Growth/differentiation factor (Gdf) 5, 6, 7 genes form a closely related subgroup belonging to the TGF-beta superfamily. In zebrafish, there are three genes that belong to the Gdf5, 6, 7 subgroup that have been named radar, dynamo, and contact. The genes radar and dynamo both encode proteins most similar to mouse GDF6. The orthologous identity of these genes on the basis of amino acid similarities has not been clear. We have identified gdf7, a fourth zebrafish gene belonging to the Gdf5, 6, 7 subgroup. To assign correct orthologies and to investigate the evolutionary relationships of the human, mouse, and zebrafish Gdf5, 6, 7 subgroup, we have compared genetic map positions of the zebrafish and mammalian genes. We have mapped zebrafish gdf7 to linkage group (LG) 17, contact to LG9, GDF6 to human chromosome (Hsa) 8 and GDF7 to Hsa2p. The radar and dynamo genes have been localized previously to LG16 and LG19, respectively. A comparison of syntenies shared among human, mouse, and zebrafish genomes indicates that gdf7 is the ortholog of mammalian GDF7/Gdf7. LG16 shares syntenic relationships with mouse chromosome (Mmu) 4, including Gdf6. Portions of LG16 and LG19 appear to be duplicate chromosomes, thus suggesting that radar and dynamo are both orthologs of Gdf6. Finally, the mapping data is consistent with contact being the zebrafish ortholog of mammalian GDF5/Gdf5.  (+info)

Cloning and functional characterization of the 5'-flanking region of the human bone morphogenetic protein-2 gene. (6/3840)

Bone morphogenetic protein-2 (BMP-2) is involved in bone formation, organogenesis or pattern formation during development. The expression of BMP-2 is regulated accurately and coordinately with that of other transforming growth factor-beta (TGF-beta) superfamily members. To elucidate the mechanism underlying the regulation of BMP-2 expression, a 6.7 kb SpeI-SalI fragment, from the P1 phage library, encompassing the 5'-flanking region of the human BMP-2 gene, was isolated and sequenced. Transcription start sites were mapped by the 5'-rapid amplification of cDNA ends (RACE) method. It has been found that the human BMP-2 gene contains, largely, two promoter regions surrounded by GC-rich sequences with several Sp1 consensus motifs. The proximal promoter possesses a single start site, whereas several start sites are clustered in the distal promoter region. Neither TATA nor CAAT consensus sequences are found in the proximity of the start sites for either promoter. Interestingly, in no case is the transcription-initiation site common between the human and mouse BMP-2 genes, although the sequence of the BMP-2 gene is well conserved in the promoter region between two species. Transient transfection experiments with the reporter fused with various lengths of the BMP-2 promoter sequence demonstrated that there exist enhancer elements in an 1.1 kb GC-rich fragment covering both promoter regions. It is noteworthy that the enhancer elements are 5'-flanked by a 790 bp strong repressor element that is characterized by numerous AT stretches. This intriguing organization may be amenable to the tight control of the expression of BMP-2 that is essential for development or bone morphogenesis.  (+info)

Convergence of transforming growth factor-beta and vitamin D signaling pathways on SMAD transcriptional coactivators. (7/3840)

Cell proliferation and differentiation are regulated by growth regulatory factors such as transforming growth factor-beta (TGF-beta) and the liphophilic hormone vitamin D. TGF-beta causes activation of SMAD proteins acting as coactivators or transcription factors in the nucleus. Vitamin D controls transcription of target genes through the vitamin D receptor (VDR). Smad3, one of the SMAD proteins downstream in the TGF-beta signaling pathway, was found in mammalian cells to act as a coactivator specific for ligand-induced transactivation of VDR by forming a complex with a member of the steroid receptor coactivator-1 protein family in the nucleus. Thus, Smad3 may mediate cross-talk between vitamin D and TGF-beta signaling pathways.  (+info)

Bmp4 is required for the generation of primordial germ cells in the mouse embryo. (8/3840)

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)

Sclerostin is a potent inhibitor of Wnt signaling and bone formation. However, there is currently no information on the relation of circulating sclerostin levels to age, gender, or bone mass in humans. Thus we measured serum sclerostin levels in a population-based sample of 362 women [123 premenopausal, 152 postmenopausal not on estrogen treatment (ET), and 87 postmenopausal on ET] and 318 men, aged 21 to 97 years. Sclerostin levels (mean ± SEM) were significantly higher in men than women (33.3 ± 1.0 pmol/L versus 23.7 ± 0.6 pmol/L, p , .001). In pre- and postmenopausal women not on ET combined (n = 275) as well as in men, sclerostin levels were positively associated with age (r = 0.52 and r = 0.64, respectively, p , .001 for both). Over life, serum sclerostin levels increased by 2.4- and 4.6-fold in the women and men, respectively. Moreover, for a given total-body bone mineral content, elderly subjects (age ≥ 60 years) had higher serum sclerostin levels than younger subjects (ages 20 to 39 ...
Bone morphogenetic protein 5 is a protein that in humans is encoded by the BMP5 gene.[1][2][3] The protein encoded by this gene is member of the TGFβ superfamily. Bone morphogenetic proteins are known for their ability to induce bone and cartilage development. BMP5 may play a role in certain cancers. Like other BMPs BMP5 is inhibited by chordin and noggin.

Bone morphogenetic protein 3, also known as osteogenin, is a protein in humans that is encoded by the BMP3 gene. The protein encoded by this gene is a member of the transforming growth factor beta superfamily. It, like other bone morphogenetic proteins (BMPs) is known for its ability to induce bone and cartilage development. It is a disulfide-linked homodimer. It negatively regulates bone density.

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 ...

Objective: Matrix Gla protein (MGP) is reported to inhibit bone morphogenetic protein (BMP) signal transduction. MGP deficiency is associated with medial calcification of the arterial wall, in a process that involves both osteogenic transdifferentiation of vascular smooth muscle cells (VSMCs) and mesenchymal transition of endothelial cells (EndMT). In this study, we investigated the contribution of BMP signal transduction to the medial calcification that develops in MGP-deficient mice. Approach and Results MGP-deficient mice (MGP-/-) were treated with one of two BMP signaling inhibitors, LDN-193189 or ALK3-Fc, beginning one day after birth. Aortic calcification was assessed in 28-day-old mice by measuring the uptake of a fluorescent bisphosphonate probe and by staining tissue sections with Alizarin red. Aortic calcification was 80% less in MGP-/- mice treated with LDN-193189 or ALK3-Fc compared with vehicle-treated control animals (P,0.001 for both). LDN-193189-treated MGP-/- mice survived ...

The importance of morphogenetic proteins (BMPs) and their antagonists in vascular development is increasingly being recognized. BMP-4 is essential for angiogenesis and is antagonized by matrix Gla protein (MGP) and crossveinless 2 (CV2), both induced in a staged fashion by the activin-like kinase receptor 1 (ALK1) after stimulation by BMP-9. In this study, however, we show that CV2 preferentially binds and inhibits BMP-9 thereby providing strong feedback inhibition for BMP-9/ALK1 signaling rather than for BMP-4/ALK2 signaling. CV2 disrupts complex formation by ALK2, ALK1, BMP-4 and BMP-9 required for the induction of both BMP antagonists. It also limits VEGF expression and proliferation of ALK1-expressing endothelial cells. In vivo, CV2 deficiency translates into a dysregulation of vascular BMP signaling, resulting in a thickened, abnormal endothelium with increased markers of endothelial differentiation. Thus, mutual regulation by BMP-9 and CV2 is essential in regulating the development of the ...

Aim: Effective treatment of premature infants with bronchopulmonary dysplasia (BPD) is lacking. We hypothesize that bone morphogenetic protein 9 (BMP9), a ligand of the TGF-β family that binds to the activin receptor-like kinase 1 (ALK1)-BMP receptor type 2 (BMPR2) receptor complex, may be a novel therapeutic option for BPD. Therefore, we investigated the cardiopulmonary effects of BMP9 in neonatal Wistar rats with hyperoxia-induced BPD. Methods: Directly after birth Wistar rat pups were exposed to 100% oxygen for 10 days. From day 2 rat pups received BMP9 (2.5 µg/kg, twice a day) or 0.9% NaCl by subcutaneous injection. Beneficial effects of BMP9 on aberrant alveolar development, lung inflammation and fibrosis, and right ventricular hypertrophy (RVH) were investigated by morphometric analysis and cytokine production. In addition, differential mRNA expression of BMP9 and its receptor complex: ALK1, BMPR2 and Endoglin, and of the ALK1 downstream target transmembrane protein 100 (TMEM100) were studied
The bone morphogenetic protein (BMP) signaling cascade is aberrantly activated in human non-small cell lung cancer (NSCLC) but not in normal lung epithelial cells, suggesting that obstructing BMP signaling may be an effective therapeutic approach for lung cancer. cascades would become ideal for anticancer drug development. In a zebrafish embryo-based structure and activity study, we previously recognized a group of highly selective small molecule inhibitors specifically antagonizing the intracellular kinase website of BMP type I receptors. In the present study, we shown that DMH1, one of such inhibitors, potently reduced lung cell expansion, advertised cell death, and decreased cell migration and attack in NSCLC cells by obstructing BMP signaling, as indicated PD318088 by suppression of Smad 1/5/8 phosphorylation and gene appearance of Identification1, Id2 and Id3. Additionally, DMH1 treatment significantly PD318088 reduced the tumor growth in human being lung malignancy xenograft model. In ...

OBJECTIVE: To characterize the bone morphogenetic protein (BMP) target cells positive for phosphorylated (P-)SMAD1/5, in rheumatoid arthritis (RA) synovium. METHODS: Synovial biopsies were obtained by needle arthroscopy. Anti-P-SMAD1/5 antibodies were used for Western blot (WB) on protein extracts from RA and normal synovium and for immunostaining of synovial biopsy sections. Positive cells were further identified by double staining for CD3, CD20, CD68, CD138, CD90, alpha smooth muscle actin (SMA), endoglin (CD105) and von Willebrand factor (VWF). In sections from early RA patients taken before and under antirheumatic treatment, the degree of inflammation and activation of the BMP pathway were quantified. RESULTS: P-SMAD1/5 protein was detected by WB in RA and to a lesser extent in normal synovium. Different P-SMAD1/5 positive cell populations were identified in RA synovium, mainly in perivascular and sublining cells. P-SMAD1/5 positive perivascular cells were alpha SMA positive and located ...

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,

This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression.

Using a biochemical approach, we confirmed the C-terminal region of HOXA13 folds into a functional DNA-binding motif and binds DNA in a sequence-specific manner. In vitro, the A13-DBD peptide facilitated the identification of HOXA13-binding sites upstream of Bmp2 and Bmp7. Quantitation of A13-DBD affinity for these enhancer elements revealed a novel series of nucleotide sequences that are preferentially bound with affinities almost 2-fold greater than the DNA regions bound by other homeodomain peptides (Catron et al., 1993).. In vivo, the interactions between HOXA13 and the Bmp2 and Bmp7 enhancer regions are conserved, as both enhancer elements were present in immunoprecipitated complexes of HOXA13 bound to DNA. The association of HOXA13 with the Bmp2 and Bmp7 enhancer regions in the developing limb strongly suggests that HOXA13 directly regulates the expression of these genes during autopod formation. It is important to note that because chromatin immunoprecipitations do not separate protein ...

Bone Morphogenetic Proteins (BMPs) are key regulators for a lot of diverse cellular processes. During embryonic development these proteins act as morphogens and play a crucial role particularly in organogenesis. BMPs have a direct impact on distinct cellular fates by means of concentration-gradients in the developing embryos. Using the diverse signaling input information within the embryo due to the gradient, the cells transduce the varying extracellular information into distinct gene expression profiles and cell fate decisions. Furthermore, BMP proteins bear important functions in adult organisms like tissue homeostasis or regeneration. In contrast to TGF-ß signaling, currently only little is known about how cells decode and quantify incoming BMP signals. There is poor knowledge about the quantitative relationships between signal input, transducing molecules, their states and location, and finally their ability to incorporate graded systemic inputs and produce qualitative responses. A key ...

Gremlin-1 (isoform-1) belongs to a group of diffusible proteins which bind to ligands of the TGF- β family and regulate their activity by inhibiting their access to signaling receptors. The interplay between TGF-β ligands and their natural antagonists has major biological significance during development processes, in which cellular response can vary considerably depending upon the local concentration of the signaling molecule. Gremlin is highly expressed in the small intestine, fetal brain, and colon and lower expression in brain, prostate, pancreas and skeletal muscle. Gremlin-1 regulates multiple functions in early development by specifically binding to and inhibiting the function of BMP-2, -4, and -7. It also plays a role in carcinogenesis and kidney branching morphogenesis. Recombinant Gremlin-1 is a 18.4 kDa protein containing 161 amino acid residues ...

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.. Bone morphogenetic proteins are osteoinductive growth factors that play a key role in cell differentiation, proliferation, migration, development, and apoptosis. BMP4 has been linked to the receptor-activator of nuclear factor-κB ligand (RANKL) mediated calcification in vessel smooth ...

The TGFβ superfamily comprises 4 signaling pathways: TGFβ, Bone Morphogenic Protein (BMP), Activin, and Nodal. This family of secreted proteins regulates immune function, cell proliferation, and epithelial to mesenchymal transition. BMPs play roles in embryogenesis as well as tissue and organ morphogenesis, whereas TGFβ signaling regulates cell growth and differentiation. Activin and Nodal signaling are also involved in cellular development. Activation of TGFβ cytokines occurs via proteolytic cleavage of their precursors, and their signaling results in activation of SMAD dependent and independent transcription. Many genes are targets of TGFβ activation, including genes involved in cell adhesion, apoptosis, and developmental processes. Dysregulation of TGF signal transduction is associated with a number of diseases including fibrosis and cancer ...

DOI: 10.11607/jomi.3543 To successfully rehabilitate edentulous patients using endosseous implants, there must be enough available bone. Several techniques have been proposed for augmentation of sites with insufficient bone volume. Although autogenous bone has long been considered the gold standard for such procedures, the limited availability of graft material and a high morbidity rate are potential disadvantages of this type of graft. An alternative is to use recombinant human bone morphogenetic protein 2 (rhBMP-2), which is able to support bone regeneration in the oral environment. These cases demonstrate the applicability of rhBMP-2 in maxillary sinus elevation and augmentation procedures in the maxilla to enable dental implant placement. The use of rhBMP-2 in alveolar augmentation procedures had several clinical benefits for these patients ...

Summary: While type 2 diabetes (T2D) is associated with higher skeletal fragility, specific risk stratification remains incompletely understood. We found volumetric bone mineral density, geometry, and serum sclerostin differences between low-fracture risk and high-fracture risk T2D women. These features might help identify T2D individuals at high fracture risk in the future. Introduction: Diabetic bone disease, an increasingly recognized complication of type 2 diabetes mellitus (T2D), is associated with high skeletal fragility. Exactly which T2D individuals are at higher risk for fracture, however, remains incompletely understood. Here, we analyzed volumetric bone mineral density (vBMD), geometry, and serum sclerostin levels in two specific T2D subsets with different fracture
Sclerostin, the product of the SOST gene, located on chromosome 17, locus q11.2 in humans, was originally believed to be a non-classical Bone morphogenetic protein (BMP) antagonist.More recently Sclerostin has been identified as binding to LRP5/6 receptors and inhibiting the Wnt signalling pathway .Wnt activation under these circumstances is antagonistic to bone formation. Although the underlying mechanisms are unclear, it is believed that the antagonism of BMP-induced bone formation by sclerostin is mediated by Wnt signalling, but not BMP signalling pathways.. Sclerostin is produced by the osteocyte and has catabolic effects on bone formation. This protein, with a length of 113 residues, has a dssp secondary structure that is 28% beta sheet (6 strands; 32 residues. Sclerostin has an inhibitory effect on the lifetime of the osteoblast. Sclerostin production by osteocytes is inhibited by parathyroid hormone, mechanical loading and cytokines including oncostatin M, cardiotrophin-1 and leukemia ...

BACKGROUND CONTEXT Increasingly, reports of frequent and occasionally catastrophic complications associated with use of recombinant human bone morphogenetic protein-2 (rhBMP-2) in spinal fusion surgeries are being published. In the original peer review, industry-sponsored publications describing the use of rhBMP-2 in spinal fusion, adverse events of these types and frequency were either not reported at all or not reported to be associated with rhBMP-2 use. Some authors and investigators have suggested that these discrepancies were related to inadequate peer review and editorial oversight. PURPOSE To compare the conclusions regarding the safety and related efficacy published in the original rhBMP-2 industry-sponsored trials with subsequently available Food and Drug Administration (FDA) data summaries, follow-up publications, and administrative and organizational databases. STUDY DESIGN Systematic review. METHODS Results and conclusions from original industry-sponsored rhBMP-2 publications regarding
Our data revealed that deficiency in CIZ increased basal bone mass in adult mice. This phenotype was through the enhancement of bone formation in vivo, increased mineralized nodule formation in bone marrow cells, and elevated expression levels of the genes encoding osteoblastic phenotype-related marker proteins including COL1, ALP, OPN, and OSX in bone in vivo. CIZ deficiency also enhanced bone marrow ablation-induced new bone formation in vivo as well as BMP injection-induced de novo osteogenesis in adult mice. Thus, CIZ acts as an inhibitor of bone formation in adult mice in vivo at least in part through its suppression of BMP actions.. CIZ localizes at adhesion plaques, transfers into nuclear compartments, binds to consensus DNA sequences, and activates promoters of the genes encoding enzymes that degrade matrix proteins (15). As CIZ is expressed in cultured osteoblasts (17-19), this protein was thought to be a modulator of osteoblastic function. However, there was an ambiguity regarding CIZ ...

BMP-14 is expressed in long bones during embryonic development and postnatally in articular cartilage. Mutations in the BMP-14 gene have been implicated in Grebe Syndrome, which is characterized by short stature, extra digits, short and deformed extremities, and in Hunter- Thompson type dwarfism. The mature and functional form of BMP-14 is a homodimer of two 120 amino-acid polypeptide chain (monomers) linked by a single disulfide bond. Each BMP-14 monomer is expressed as the C-terminal part of a precursor polypeptide, which also contains a 27 amino-acid signal peptide and a 354 amino-acid propeptide. This precursor undergoes intracellular dimerization, and upon secretion it is processed by a furin-type protease. Recombinant human BMP-14 is a 27.0 kDa homodimeric disulfide-linked protein consisting of two 120 amino acids ...
Our results identify BMPR2/ALK2 and BMPR2/ALK3 as key receptors that mediate proangiogenic BMP signaling in the early postnatal retina and reveal regional differences among BMPR1s by analysis of parallel genetic experiments in a defined vascular bed. Deletion of the common BMPR2 receptor reduced vascular sprouting and density. Deletion of ALK3, which is ubiquitously expressed in retinal endothelial cells, also dramatically reduced vascular sprouting and density, while loss of ALK2, which is enriched behind the vascular front, did not significantly affect sprouting but reduced overall vessel density. Therefore, we propose that spatially regulated BMPR1 expression fine-tunes endothelial cell responses to proangiogenic BMP ligands in development. Since expression of BMP ligands selective for ALK2 and ALK3 is elevated during retinal angiogenesis, it is tempting to speculate that BMP6/7-ALK2/3-BMPR2 signaling axis may provide essential input for the developing retina.. Since the phenotype of ...
Reliable and effective communication between neurons and their postsynaptic targets across the synaptic cleft is critical for the formation, growth, and plasticity of neuronal synapses. One mode of this transsynaptic communication is retrograde signaling, in which target cells provide molecular signals to influence presynaptic neurons (Tao and Poo, 2001; Marqués and Zhang, 2006). In Drosophila melanogaster, Glass bottom boat (Gbb), a bone morphogenetic protein (BMP), acts as a critical retrograde signal that promotes synaptic growth and neurotransmitter release at the neuromuscular junction (NMJ; Haghighi et al., 2003; McCabe et al., 2003; Goold and Davis, 2007). Genetic experiments have shown that the retrograde Gbb signal is sensed by a presynaptic receptor complex formed by the type II BMP receptor wishful thinking (Wit) and either of two type I BMP receptors, thick veins (Tkv) and saxophone (Sax; Aberle et al., 2002; Marqués et al., 2002; Rawson et al., 2003; McCabe et al., 2004; ...
The transforming growth factor β (TGF-β) superfamily comprises more than 30 ligands that play essential roles during early vertebrate development in the specification and subsequent patterning of the germ layers and in tissue homeostasis in adult organisms. Deregulation of signaling downstream of many of these ligands has been implicated in human diseases such as cancer and fibrosis, in wound healing disorders, and in several hereditary conditions (7, 37). The TGF-β superfamily ligands elicit their pleiotropic effects by signaling to the nucleus and inducing new programs of gene expression. The large number of ligands in this superfamily signal to the nucleus through a much smaller number of receptors and Smads, which act as intracellular signal transducers (14). Thus, different ligands utilize common pathway components. This raises important questions about how cells respond specifically to individual ligands and how cells integrate and interpret signals received from multiple ligands ...
Treatment with 0.4mg/mL rhBMP-2 resulted in significant growth changes and fusion of the coronal sutures bilaterally, anterior sagittal suture, and frontonasal suture by cephalometric analyses at 42 days postoperatively (p,0.05). Growth changes appeared greatest in the nasal region and less in the bicoronal and anterior sagittal regions. No significant differences in cranial growth were noted with use of 100-ug/mL biopatterned rhBMP-2 when compared to the empty defect group. Qualitative uCT analysis revealed comparable bony defect healing between rhBMP-2 groups. Application of high-dose, 0.4mg/mL rhBMP-2 resulted in pansynostosis upon uCT analysis, further verifying cranial growth restriction. Low-dose, 100-ug/mL biopatterned rhBMP-2 consistently regenerated bone within the surgical defect margin without evidence of extra-sutural invasion ...

BMP-6 and BMP-7 both inhibited FSH- and forskolin (FSK)-induced progesterone synthesis and reduced cAMP synthesis independent of the presence or absence of oocytes. BMP-7 also increased FSH-induced estradiol production, and the response was further augmented in the presence of oocytes. In contrast, BMP-6 had no impact on estradiol synthesis regardless ...

Bone morphogenetic proteins (BMP) are thought to be important in breast cancer promotion and progression. We evaluated genetic variation in BMP-related genes and breast cancer risk among Hispanic (2,111 cases, 2,597 controls) and non-Hispanic White (NHW) (1,481 cases, 1,586 controls) women who participated in the 4-Corner's Breast Cancer Study, the Mexico Breast Cancer Study and the San Francisco Bay Area Breast Cancer Study. BMP genes and their receptors evaluated include ACVR1, AVCR2A, ACVR2B, ACVRL1, BMP1, BMP2, BMP4, BMP6, BMP7, BMPR1A, BMPR1B, BMPR2, MSTN and GDF10. Additionally, 104 ancestral informative markers were assessed to discriminate between European and native American ancestry. The importance of estrogen on BMP-related associations was suggested through unique associations by menopausal status and estrogen (ER) and progesterone (PR) receptor status of tumors. After adjustment for multiple comparisons ACVR1 (8 SNPs) was modestly associated with ER+PR+ tumors [odds ratios ...

AU - Harvey, Brandon K.. AU - Hoffer, Barry J.. AU - Wang, Yun. PY - 2009/2/1. Y1 - 2009/2/1. N2 - Retinoic acid (RA), a biologically active derivative of vitamin A, has protective effects against damage caused by H2O2 or oxygen-glucose deprivation in mesangial and PC12 cells. In cultured human osteosarcoma cells, RA enhances the expression of bone morphogenetic protein-7 (BMP7), a trophic factor that reduces ischemia- or neurotoxin-mediated neurodegeneration in vivo. The purpose of this study is to examine whether RA reduces ischemic brain injury through a BMP7 mechanism. We found that intracerebroventricular administration of 9-cis-retinoic acid (9cRA) enhanced BMP7 mRNA expression, detected by RT-PCR, in rat cerebral cortex at 24 hr after injection. Rats were also subjected to transient focal ...
article{68313ef7-27fc-4663-8f97-88e1ccb5049b, abstract = {The central role of bone morphogenetic proteins (BMPs) in the remodelling process of the human skeleton has been identified in numerous experimental and clinical studies. BMPs appear to be key agents in the osteoblastic differentiation of mesenchymal stem cells, and more recent evidence implicates them with the cells of the osteoclastic lineage. BMP-2, BMP-4, BMP-6 and BMP-7 have been studied in the context of osteoporosis and have been associated with its pathophysiological pathways. The theoretical advantages of local or systemic treatment of osteoporotic fractures with BMPs include the potential of inducing a rapid increase in bone strength locally at the fractured area and systemically in the entire skeleton, as well as accelerating the bone-healing period. Animal models of osteoporotic fractures suggested that the induction of new bone by local or systemic use of BMP-7 should be investigated as potential bone augmentation therapy to ...

Signaling by Bmp receptors is mediated mainly by Smad proteins. In this study, we show that a targeted null mutation of Ecsit, encoding a signaling intermediate of the Toll pathway, leads to reduced cell proliferation, altered epiblast patterning, impairment of mesoderm formation, and embryonic lethality at embryonic day 7.5 (E7.5), phenotypes that mimic the Bmp receptor type1a (Bmpr1a) null mutant. In addition, specific Bmp target gene expression is abolished in the absence of ...

Bone morphogenetic protein 2 opposes Shh-mediated proliferation in cerebellar granule cells through a TIEG-1-based regulation of Nmyc.
DescriptionDevelopment is controlled by a surprisingly small number of genetic pathways. One such pathway is called the bone morphogenetic protein (BMP) pathway, similar from flies to humans. We used the common fruit fly, Drosophila melanogaster, to study the BMP pathway during Drosophila oogenesis, the formation of the egg. While the pathway is relatively simple, there exist combinations between the three different ligands, and four different receptors. My work focused largely on the two type II receptor, specifically on Wishful thinking (WIT). Much is known about the dynamic expression of the type I receptor during oogenesis, Thickveins. However, the pathway requires action of both type I and type II receptors. We found that WIT performs a necessary role during oogenesis and is regulated, indirectly, by BMP signaling. WIT is required for proper patterning of pathway target genes and necessary for proper formation of the eggshell. We also used a new technology, CRISPR/Cas9, to specifically ...
Establishment of mesodermal tissues in the amphibian body involves a series of inductive interactions probably elicited by a variety of peptide growth factors. Results reported here suggest that mesodermal patterning involves an array of signalling molecules including DVR-4, a TGF-beta-like molecule. We show that ectopic expression of DVR-4 causes embryos to develop with an overall posterior and/or ventral character, and that DVR-4 induces ventral types of mesoderm in animal cap explants. Moreover, DVR-4 overrides the dorsalizing effects of activin. DVR-4 is therefore the first molecule reported both to induce posteroventral mesoderm and to counteract dorsalizing signals such as activin. Possible interactions between these molecules resulting in establishment of the embryonic body plan are discussed.. ...
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 ...
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 ...
Yu focuses on bone morphogenetic proteins (BMP) - groups of signaling molecules that are vital to tissue development - and how a BMP receptor mutation signals the body to grow bone where it does not belong. Yu and his team tried to recreate the disease in mouse models to gain more insight into how it occurs and its cells of origin. Though targeting bone marrow and several blood vessel-associated cells in mice with the mutation did not produce the intended result, focusing on other types of cells did.. Targeting expression of the mutant receptor to skeletal muscle interstitial cells - the cells that lie between muscle fiber cells - didnt immediately produce bone formation, but once there was an injury to the muscle, bone began to develop.. This was very reminiscent of some of the observations we had from people who experienced the replacement of muscle tissue with bone following injury, said Yu.. When the team targeted expression of the mutant receptor to tendon and ligament cells of mice, ...
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

We next investigated the possible role of Bmp6 in the induction of hepcidin by inflammation. Hepcidin is part of the type II acute-phase response and is thought to have a crucial role in anemia of chronic disease. Whereas hepcidin is induced by activation of the inflammatory pathway in Hfe2-deficient mice(14), this induction is not observed in mice with liver-specific Smad4 deficiency(11). We therefore set out to determine whether lipopolysaccharide (LPS)-dependent induction of hepcidin requires Bmp6 by treating Bmp6 mutant mice and wild-type controls with LPS or saline solution. As expected, the acute-phase genes Il6, Tnf and Crp were strongly induced in LPS-treated mice as compared with saline-treated animals (see Supplementary Figs. 6 and 7 online). Hamp gene expression was induced about 24-fold in response to the LPS treatment in Bmp6 -/- mice and 2.6-fold in wild-type controls (Fig. 1). Notably, Hamp mRNA levels in LPS- injected Bmp6 -/- animals did not reach those of wild-type controls. ...
Purpose.: There are limited studies on the factors that regulate the processing of TGF-β2 and extracellular matrix (ECM) proteins into their mature form. Bone morphogenic protein 1 (BMP1) is an enzyme responsible for the cleavage and maturation of growth factors and ECM proteins. The purpose of our study was to determine whether cultured human trabecular meshwork (TM) cells express BMP1, BMP1 expression is regulated by TGF-β2, BMP1 is biologically active, and BMP1 regulates LOX activity. Methods.: Primary human TM cells were isolated and subjected to quantitative PCR (qPCR) and Western immunoblotting (WB) for BMP1. BMP1 immunolocalization was performed in TM tissues. qPCR was used to determine BMP1 mRNA expression and WB results were used to determine BMP1 protein expression. BMP1 activity was measured in TM cells treated with TGF-β2 or with a combination of TGF-β2/UK383367. Lysyl oxidase (LOX) enzyme activity was evaluated by WB in TM cells treated with BMP1 or with a combination of ...

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 ...
This will be one of the shorter posts.. It is almost been completely concluded that the glycoprotein Noggin and the gene that creates inhibits longitudinal growth. Mutations in the gene often leads to tall stature.. from the wikipedia article on Noggin (HERE). Noggin, also known as NOG, is a protein which in humans is encoded by the NOG gene.[1]. Noggin inhibits TGF-β signal transduction by binding to TGF-β family ligands and preventing them from binding to their corresponding receptors. Noggin plays a key role in neural induction by inhibiting BMP4, along with other TGF-β signaling inhibitors such as chordin and follistatin. Mouse knockout experiments have demonstrated that noggin also plays a crucial role in bone development, joint formation, and neural tube fusion. Molecular biology. The secreted polypeptide noggin, encoded by the NOG gene, binds and inactivates members of the transforming growth factor-beta (TGF-beta) superfamily signaling proteins, such as bone morphogenetic protein-4 ...
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 ...

Gene Information The protein encoded by this gene is a member of the bone morphogenetic protein (BMP) family and the TGF-beta superfamily. This group of proteins is characterized by a polybasic proteolytic processing site which is cleaved to produce a mature protein containing seven conserved cysteine residues. The members of this family are regulators of cell growth and differentiation in both embryonic and adult tissues. Studies in rodents suggest that this protein plays a role in the adult liver and in differentiation of cholinergic central nervous system neurons. [provided by RefSeq Jul 2008]. ...
