They are PROTEIN-SERINE-THREONINE KINASES that mediate SIGNAL TRANSDUCTION PATHWAYS through SMAD PROTEINS.Bone Morphogenetic Proteins: Bone-growth regulatory factors that are members of the transforming growth factor-beta superfamily of proteins. They are synthesized as large precursor molecules which are cleaved by proteolytic enzymes. The active form can consist of a dimer of two identical proteins or a heterodimer of two related bone morphogenetic proteins.Bone Morphogenetic Protein 2: A potent osteoinductive protein that plays a critical role in the differentiation of osteoprogenitor cells into OSTEOBLASTS.Smad1 Protein: A receptor-regulated smad protein that undergoes PHOSPHORYLATION by BONE MORPHOGENETIC PROTEIN RECEPTORS.

They were originally identified as a class of proteins that are related to the mothers against decapentaplegic protein, Drosophila and sma proteins from CAENORHABDITIS ELEGANS.Activin Receptors, Type II: One of the two types of ACTIVIN RECEPTORS. They are membrane protein kinases belonging to the family of PROTEIN-SERINE-THREONINE KINASES. The major type II activin receptors are ActR-IIA and ActR-IIB.Activin Receptors, Type I: One of the two types of ACTIVIN RECEPTORS or activin receptor-like kinases (ALK'S). There are several type I activin receptors. The major active ones are ALK-2 (ActR-IA) and ALK-4 (ActR-IB).Transforming Growth Factor beta: A factor synthesized in a wide variety of tissues. It acts synergistically with TGF-alpha in inducing phenotypic transformation and can also act as a negative autocrine growth factor. TGF-beta has a potential role in embryonal development, cellular differentiation, hormone secretion, and immune function. TGF-beta is found mostly as homodimer forms of separate gene products TGF-beta1, TGF-beta2 or TGF-beta3. Heterodimers composed of TGF-beta1 and 2 (TGF-beta1.2) or of TGF-beta2 and 3 (TGF-beta2.3) have been isolated. The TGF-beta proteins are synthesized as precursor proteins.Protein-Serine-Threonine Kinases: A group of enzymes that catalyzes the phosphorylation of serine or threonine residues in proteins, with ATP or other nucleotides as phosphate donors.Signal Transduction: The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.Receptors, Interleukin-1 Type II: An interleukin-1 receptor subtype that competes with the INTERLEUKIN-1 RECEPTOR TYPE I for binding to INTERLEUKIN-1ALPHA and INTERLEUKIN-1BETA. The interleukin-1 type II receptor appears to lack signal transduction capability. Therefore it may act as a "decoy" receptor that modulates the activity of its ligands. Both membrane-bound and soluble forms of the receptor have been identified.Bone Morphogenetic Protein 6: A bone morphogenetic protein that is a potent inducer of BONE formation. It plays additional roles in regulating CELL DIFFERENTIATION of non-osteoblastic cell types and epithelial-mesenchymal interactions.Pulmonary Artery: The short wide vessel arising from the conus arteriosus of the right ventricle and conveying unaerated blood to the lungs.Monocrotaline: A pyrrolizidine alkaloid and a toxic plant constituent that poisons livestock and humans through the ingestion of contaminated grains and other foods.

Characterization of bone morphogenetic protein-6 signaling pathways in osteoblast differentiation. (1/312)

Bone morphogenetic protein (BMP)-6 is a member of the transforming growth factor (TGF)-(&bgr;) superfamily, and is most similar to BMP-5, osteogenic protein (OP)-1/BMP-7, and OP-2/BMP-8. In the present study, we characterized the endogenous BMP-6 signaling pathway during osteoblast differentiation. BMP-6 strongly induced alkaline phosphatase (ALP) activity in cells of osteoblast lineage, including C2C12 cells, MC3T3-E1 cells, and ROB-C26 cells. The profile of binding of BMP-6 to type I and type II receptors was similar to that of OP-1/BMP-7 in C2C12 cells and MC3T3-E1 cells; BMP-6 strongly bound to activin receptor-like kinase (ALK)-2 (also termed ActR-I), together with type II receptors, i.e. BMP type II receptor (BMPR-II) and activin type II receptor (ActR-II). In addition, BMP-6 weakly bound to BMPR-IA (ALK-3), to which BMP-2 also bound. In contrast, binding of BMP-6 to BMPR-IB (ALK-6), and less efficiently to ALK-2 and BMPR-IA, together with BMPR-II was detected in ROB-C26 cells. Intracellular signalling was further studied using C2C12 and MC3T3-E1 cells. Among the receptor-regulated Smads activated by BMP receptors, BMP-6 strongly induced phosphorylation and nuclear accumulation of Smad5, and less efficiently those of Smad1. However, Smad8 was constitutively phosphorylated, and no further phosphorylation or nuclear accumulation of Smad8 by BMP-6 was observed. These findings indicate that in the process of differentiation to osteoblasts, BMP-6 binds to ALK-2 as well as other type I receptors, and transduces signals mainly through Smad5 and possibly through Smad1.  (+info)

Bone morphogenetic proteins-2 and -4: negative growth regulators in adult retinal pigmented epithelium. (2/312)

PURPOSE: To determine the relative level and localization of bone morphogenetic protein (BMP-4 mRNA in the retina and retinal pigmented epithelium (RPE) under normal and pathologic conditions, to seek clues regarding possible functions. METHODS: Clones isolated from an RPE cDNA library were sequenced and used as probes for northern blot analysis. Expression in the retina and RPE was investigated in mouse models using reverse transcription-polymerase chain reaction (RT-PCR) and in situ hybridization. The effect of recombinant proteins on RPE proliferation was investigated by thymidine incorporation. RESULTS: Bovine clones with high homology to BMP-2 and BMP4 were isolated from a subtracted RPE cDNA library. Northern blot analysis using the clones as probes demonstrated abundant and differential expression in adult bovine RPE, but with RT-PCR and in situ hybridization, expression was also demonstrated in mouse retinal neurons. In mice with oxygen-induced ischemic retinopathy there was a striking decrease in BMP-4 mRNA in the retina within 6 hours of the onset of hypoxia that was maintained for at least 5 days. In mice with inherited photoreceptor degeneration, there was a dramatic decrease in BMP4 mRNA in retina and RPE during and after the degeneration. mRNA for the type II BMP receptor was observed in freshly isolated and cultured RPE cells, isolated retina, and freshly isolated bovine aortic endothelial cells. Thymidine incorporation in early-passage RPE cells showed a 14-fold stimulation above control with 5% serum that was decreased to 322%, 393%, and 313% in the presence of BMP-2 (10 ng/ml), BMP4 (10 ng/ml), and transforming growth factor (TGF)-,1 (2 ng/ml), respectively. CONCLUSIONS: BMP-2 and BMP-4 may serve as negative growth regulators in the retina and RPE that are downregulated by injury, to allow tissue repair. Modulation of expression of the BMPs may provide a means to control the exaggerated wound repair that occurs in proliferative retinopathies.  (+info)

Requirement of autocrine signaling by bone morphogenetic protein-4 for chondrogenic differentiation of ATDC5 cells. (3/312)

Mouse EC cell line ATDC5 undergoes differentiation to form cartilage nodules via the cellular condensation stage in the presence of insulin. ATDC5 cells expressed transcripts for bone morphogenetic protein-4 (BMP-4), and type IA and type II BMP receptors. Moreover, cells retained responsiveness to BMP-4, which induced the formation of chondrocytes in the culture. When transfected with a kinase domain-truncated type IA BMP receptor construct, cells failed to undergo differentiation beyond the condensation stage even in the presence of insulin. The soluble form of type IA BMP receptor also blocked the formation of chondrocytes in a dose dependent manner. These lines of evidence suggested that autocrine BMP-4 signaling is required for the conversion of chondrogenic precursor cells into chondrocytes.  (+info)

Targeted misexpression of constitutively active BMP receptor-IB causes bifurcation, duplication, and posterior transformation of digit in mouse limb. (4/312)

Members of bone morphogenetic proteins (BMPs) play important roles in many aspects of vertebrate embryogenesis. In developing limbs, BMPs have been implicated in control of anterior-posterior patterning, outgrowth, chondrogenesis, and apoptosis. These diverse roles of BMPs in limb development are apparently mediated by different BMP receptors (BMPR). To identify the developmental processes in mouse limb possibly contributed by BMP receptor-IB (BMPR-IB), we generated transgenic mice misexpressing a constitutively active Bmpr-IB (caBmpr-IB). The transgene driven by the mouse Hoxb-6 promoter was ectopically expressed in the posterior mesenchyme of the forelimb bud, the lateral plate mesoderm, and the whole mesenchyme of the hindlimb bud. While the forelimbs appeared normal, the transgenic hindlimbs exhibited several phenotypes, including bifurcation, preaxial polydactyly, and posterior transformation of the anterior digit. However, the size of bones in the transgenic limbs seemed unaltered. Defects in sternum and ribs were also found. The bifurcation in the transgenic hindlimb occurred early in the limb development (E10.5) and was associated with extensive cell death in the mesenchyme and occasionally in the apical ectodermal ridge (AER). Sonic hedgehog (Shh) and Patched (Ptc) expression appeared unaffected in the transgenic limb buds, suggesting that the BMPR-IB mediated signaling pathway is downstream from Shh. However, ectopic Fgf4 expression was found in the anterior AER, which may account for the duplication of the anterior digit. An ectopic expression of Gremlin found in the transgenic limb bud would be responsible for the ectopic Fgf4 expression. The observations that Hoxd-12 and Hoxd-13 expression patterns were extended anteriorly provide a molecular basis for the posterior transformation of the anterior digit. Together these results suggest that BMPR-IB is the endogenous receptor to mediate the role of BMPs in anterior-posterior patterning and apoptosis in mouse developing limb. In addition, BMPR-IB may represent a critical component in the Shh/FGF4 feedback loop by regulating Gremlin expression.  (+info)

BMP receptors in limb and tooth formation. (5/312)

Members of the TGF-beta superfamily signal through receptor complexes comprised of type I and type II receptors. These receptors, which are serine/threonine kinases, form two new classes of transmembrane receptor kinases. The activity of both of the kinases is necessary for signal transduction in response to ligand binding. Bone morphogenetic proteins (BMPs), which are members of the TGF-beta superfamily, bind to multiple type I and type II receptors. There is growing evidence to support the hypothesis that the BMP receptors are differentially regulated during development and that they have both unique and overlapping functions. Thus, the nature and distribution of the BMP receptors, which are reviewed here in the context of the development of limbs and teeth, appear to be critical in the control of the diverse activities of BMPs.  (+info)

BMP type II receptor is required for gastrulation and early development of mouse embryos. (6/312)

Bone morphogenetic proteins (BMPs), members of the transforming growth factor-beta superfamily, play a variety of roles during mouse development. BMP type II receptor (BMPR-II) is a type II serine/threonine kinase receptor, which transduces signals for BMPs through heteromeric complexes with type I receptors, including activin receptor-like kinase 2 (ALK2), ALK3/BMPR-IA, and ALK6/BMPR-IB. To elucidate the function of BMPR-II in mammalian development, we generated BMPR-II mutant mice by gene targeting. Homozygous mutant embryos were arrested at the egg cylinder stage and could not be recovered at 9.5 days postcoitum. Histological analysis revealed that homozygous mutant embryos failed to form organized structure and lacked mesoderm. The BMPR-II mutant embryos are morphologically very similar to the ALK3/BMPR-IA mutant embryos, suggesting that BMPR-II is important for transducing BMP signals during early mouse development. Moreover, the epiblast of the BMPR-II mutant embryo exhibited an undifferentiated character, although the expression of tissue-specific genes for the visceral endoderm was essentially normal. Our results suggest that the function of BMPR-II is essential for epiblast differentiation and mesoderm induction during early mouse development.  (+info)

Expression of bone morphogenetic protein receptors type-IA, -IB and -II correlates with tumor grade in human prostate cancer tissues. (7/312)

Bone morphogenetic proteins (BMPs) are potential regulators of prostate cancer cell growth and metastasis that signal through an interaction with BMP membrane receptors (BMPRs) type I and type II. In the present study, Western blot and immunohistochemical analysis of BMPRs were carried out in benign and malignant human prostate tissues to explain the loss of BMP response in human prostate cancer cells. The results demonstrated that the benign prostate specimens expressed high levels of all three BMPRs. In normal prostate, BMPRs were localized predominantly to epithelial cells. Among prostate cancer specimens, well-differentiated cancers were positive for the expression of BMPR-II, BMPR-IA, and BMPR-IB, for the most part. In contrast, only 1 of 10 poorly differentiated prostate cancer cases was positive for each of the three BMPRs (P < 0.005 for all three receptors). Taken together, these results indicate that human prostate cancer cells frequently exhibit loss of expression of BMPRs and suggest that loss of BMPRs may play an important role during the progression of prostate cancer.  (+info)

Engagement of bone morphogenetic protein type IB receptor and Smad1 signaling by anti-Mullerian hormone and its type II receptor. (8/312)

Anti-Mullerian hormone induces the regression of fetal Mullerian ducts and inhibits the transcription of gonadal steroidogenic enzymes. It belongs to the transforming growth factor-beta family whose members signal through a pair of serine/threonine kinase receptors and Smad effectors. Only the anti-Mullerian hormone type II receptor has been identified. Our goal was to determine whether anti-Mullerian hormone could share a type I receptor with another family member. Co-immunoprecipitation of known type I receptors with anti-Mullerian hormone type II receptor clearly showed that the bone morphogenetic protein type IB receptor was the only cloned type I receptor interacting in a ligand-dependent manner with this type II receptor. Anti-Mullerian hormone also activates the bone morphogenetic protein-specific Smad1 pathway and the XVent2 reporter gene, an anti-Mullerian hormone type II receptor-dependent effect abrogated by a dominant negative version of bone morphogenetic protein type IB receptor. Reverse amplification experiments showed that bone morphogenetic protein type IB receptor is co-expressed with anti-Mullerian hormone type II receptor in most anti-Mullerian hormone target tissues. Our data support a model in which a ligand, anti-Mullerian hormone, gains access to a shared type I receptor and Smad1 system through a highly restricted type II receptor.  (+info)

In the present study, we found that (1) the protein expression of BMPR2 is modulated by the miR-17/92 cluster without affecting the BMPR2 mRNA levels; (2) this regulatory effect is driven by 2 distinct miRNAs, ie, miR-17-5 and miR-20a, through conserved seed matches within the 3′UTR of BMPR2; and (3) IL-6 regulates the expression of the miR-17/92 in HPAEC by signaling through STAT3. Moreover, we could show that (4) the promoter region of C13orf25 exhibits an evolutionary conserved STAT3-binding site and, finally, that (5) persistent activation of STAT3 leads to a strong upregulation of mature miR-20a, which, in turn, reduces the expression of BMPR2 protein. Taken together, our findings offer a novel mechanistic explanation for the downregulation of BMPR2, which has been repeatedly described as important feature in the pathogenesis of pulmonary hypertension.. The cell surface receptor BMPR2 is essential for the modulation of differentiation, proliferation and the fibrous matrix production of ...
This study has demonstrated the cellular distribution of BMPR-II in the normal and hypertensive lung. Our observations suggest that this receptor is predominantly expressed by endothelial cells in the pulmonary circulation, with a lower level of expression in vascular smooth muscle. In addition, BMPR-II is expressed within the characteristic lesions found in PPH, specifically by endothelial cells of plexiform lesions and by endothelial and myofibroblast cells in the intimal lesions. The cellular localization of BMPR-II to key cell types implicated in the vascular remodeling of PPH supports the suggestion from genetic studies that mutations in this receptor play a causal role in disease pathogenesis. Furthermore, the observation that BMPR-II protein expression is reduced in the lungs of patients with severe PH, most markedly in patients harboring heterozygous germline mutations in BMPR2, suggests that reduced BMPR-II signaling may be implicated not only in the in the pathogenesis of PPH in which ...
Significant progress in the knowledge about the role of TGF-β in the response to pressure overload has been achieved by studies in left heart failure. Although it is known that TGF-β is associated with maladaptive hypertrophy, inflammation, and fibrosis in various models and diseases, the study of Koitabashi et al was the first to show that TGF-β plays a central role in the cardiac maladaptive response to pressure overload.32-36 However, because the LV has a different embryological origin and the amount of pressure overload in right and left heart failure is not comparable, these results cannot be directly extrapolated.37,38. Until recently, little was known about the effects of BMPR2 mutations on RV adaptation in PAH. First, Megalou et al39 showed the importance of TGF-β in the hypertrophic response in the myocardium of pulmonary hypertensive monocrotaline rats, and, more recently, Hemnes et al24 demonstrated impaired hypertrophy attributable to an altered cardiac energy metabolism in the ...

OBJECTIVE: To evaluate the presence of cells of an early mesenchymal lineage, as judged by the expression of bone morphogenetic protein receptors (BMPRs), in the joints of normal individuals and patients with rheumatoid arthritis (RA). METHODS: Synovial fluids, single cell suspensions of cultured fibroblast-like synoviocytes (FLS), and synovial tissues were examined by immunohistology with antibodies to BMPR type IA (BMPRIA), BMPRIB, and BMPRII and then quantified using computerized image analysis. Other antibodies were evaluated by cytofluorography. RESULTS: In primary cultures of joint effusions from patients with RA and other forms of inflammatory arthritis, there were large adherent cells with the appearance of either fibroblasts or stromal cells that stained with antibodies to mesenchymal elements-CD44, type I collagen, alpha-actin, and vimentin-but not with antibodies to hematopoietic markers. These cells proliferated rapidly, expressed BMPRIA and BMPRII, and soon became the predominant cells in

GW788388 is a new TGF-beta type I receptor inhibitor with a much improved pharmacokinetic profile compared with SB431542. We studied its effect in vitro and found that it inhibited both the TGF-beta type I and type II receptor kinase activities, but not that of the related bone morphogenic protein type II receptor. Further, it blocked TGF-beta-induced Smad activation and target gene expression, while decreasing epithelial-mesenchymal transitions and fibrogenesis
The bone morphogenetic protein (BMP) receptors are a family of transmembrane serine/threonine kinases that include the type I receptors BMPR1A and BMPR1B and the type II receptor BMPR2. These receptors are also closely related to the activin receptors, ACVR1 and ACVR2. The ligands of these receptors are members of the TGF-beta superfamily. TGF-betas and activins transduce their signals through the formation of heteromeric complexes with 2 different types of serine (threonine) kinase receptors: type I receptors of about 50-55 kD and type II receptors of about 70-80 kD. Type II receptors bind ligands in the absence of type I receptors, but they require their respective type I receptors for signaling, whereas type I receptors require their respective type II receptors for ligand binding ...
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; ...
A correctly functioning nervous system requires that neural circuits be precisely wired during development. A growing axon must travel through a constantly changing environment, bypassing inappropriate targets to make the correct synapse. To accomplish this feat, axons are directed along the proper path by attractive and repellent cues in the embryonic environment. In addition to directional information, it is critical that axons receive such guidance input at the appropriate time to correctly advance. ❧ Morphogens, signaling molecules that specify cell identity, have been found to also act as axon guidance cues, raising the possibility that the mechanisms that establish neural cell fate are also utilized to assemble neuronal circuits. In the embryonic vertebrate spinal cord, Bone Morphogenetic Proteins (BMPs) initially induce the identity of dorsal interneuron type 1 (dI1) commissural neurons, then subsequently repel their axons - two biologically distinct processes. Specification of cell ...

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 ...

PAH may be heritable. Much of what is known about the genetic basis of PAH is related to bone morphogenetic protein receptor 2 (BMPR2). We studied variants in BMPR2, endothelin-1 (ET-1) and nitric oxide synthase 2 (NOS2).. Patients with idiopathic and associated PAH were included. DNA was amplified for the 17 validated amplicons spanning the coding sequence of BMPR2 gene. For ET-1 gene the polymorphism K198N was selected because homozygous for Asn (T/T genotype) have higher levels of ET-1. NOS2 play a key role in endothelial dysfunction. CCTTT repeat polymorphism was studied.. 30 PAH patients (14 idiopathic, 16 associated) and 50 controls were included. BMPR2: 21 mutations were identified in 22 patients. Six were missense, one nonsense, 3 deletions and 7 synonymous changes. According to PolyPhen software changes with involvement in the pathogenesis were present in 4 of the 30 patients (14%). Various missense polymorphisms were detected. Although these polymorphisms causes an amino-acid change, ...

Measurements and Main results At 17 weeks post-infection there was no significant difference in RVSP, the degree of RV hypertrophy, mean area of liver vasculature, mean number of liver vessels or liver weight between infected BMPR-II + / + and BMPR-II +/- mice. However, there was a significant reduction in body weight, a significant increase in lung egg deposition and lung cytokine expression in the BMPR-II +/- mice compared to the wild-type mice 17 weeks post-infection. There was no significant difference in serum or liver cytokine levels. We saw a significant increase in pulmonary vessel wall thickness in both BMPR-II + / + and BMPR-II +/- mice infected mice, compared to their respective non-infected controls. There was no difference in the ability of macrophages from BMPR-II + / + and BMPR-II +/- mice to phagocytose fluorescently tagged beads.. ...
5266 Bone morphogenesis proteins (BMP2) are members of the transforming growth factor beta superfamily which includes multifunctional peptides that regulate cell proliferation, differentiation and other functions in many cellular systems. BMP2 is associated with the regulation of proliferation, survival and self-renewal of stem cells. BMP2 binds to a receptor complex composed of type I and type II BMP2 receptors, which are membrane-spanning serine/threonine kinases and activate downstream Smad proteins. Using a 35,000 element custom cDNA microarray chip, enriched for glial tumor transcripts, we found that BMP2 was highly expressed in astrocytic tumors as compared to normal brains, whereas no differences in the expression of BMP6 and BMP7 were observed. These data were further validated by RT-PCR and Western blot analysis. Similarly, we found that glioma cell lines expressed significantly higher levels of BMP2 as compared to normal human astrocytes. In contrast to the enhanced expression of BMP2 ...
Cytokines of the TGFβ superfamily, including BMPs, signal through a complex of type I and type II transmembrane receptors at the plasma membrane (Figure 1A). There are four different type I and three type II receptors for BMPs. Both types of receptor contain a disulphide-bonded extracellular domain that binds the BMP ligand, a transmembrane region, a juxtamembrane region and a kinase domain. The type I receptor also contains a glycine and serine-rich region (GS-box) adjacent to its kinase domain. In addition, one splice-form of the BMP type II receptor (BMPRII) has a large C-terminal extension comprising 508 amino acids after the kinase domain. This tail region is known to be functionally important and mediates interactions with a plethora of intracellular proteins. To date, its structure has not yet been solved.. BMPs and TGFβs are active as covalent dimers, and bind to heterotetrameric complexes of type I and type II receptors (Fig. 1B). However, they have distinct modes of binding. While ...

Little is known about functional differences between the three type I receptors. Here, we have investigated consequences of constitutively active (ca) and dominant negative (dn) type I receptor overexpression in adult-derived hippocampal progenitor cells (AHPs). The dn receptors have a nonfunctional intracellular but functional extracellular domain. They thus trap BMPs that ...

Data describing the natural history of idiopathic and familial pulmonary arterial hypertension were derived from a registry conducted at our institution prior to 2006. Since then, targeted therapies for pulmonary arterial hypertension have been introduced in China. It is probably that the prognosis of Chinese patients with WHO group I pulmonary arterial hypertension and WHO group IV pulmonary hypertension due to chronic thromboembolic pulmonary hypertension has also been improved as western countries. Therefore, the aim of the present study was to describe real-world outcome of Chinese patients with pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension and identify factors that may predict outcome. Our study will provide an updated picture of the clinical course of a more broadly defined scope of pulmonary hypertension and the effects of current therapy on survival, enabling the collection of data on demographics, clinical course, treatments, and outcomes ...
Mutations in bone morphogenetic protein receptor 2 (BMPR2) are present in ,80% of familial and ~20% of sporadic pulmonary arterial hypertension (PAH) patients. Furthermore dysfunctional BMP signaling is a general feature of pulmonary hypertension even in non-familial PAH.. We therefore hypothesized that increasing BMP signaling might prevent and reverse the disease. We screened , 3500 FDA approved drugs for their propensity to increase BMP signaling and found FK506 (Tacrolimus) to be a strong activator of BMP signaling. Tacrolimus restored normal function of pulmonary artery endothelial cells, prevented and reversed experimental PAH in mice and rats.. Given that Tacrolimus is already FDA approved with a known side-effect profile, it is an ideal candidate drug to use in patients with pulmonary arterial hypertension.. The aims of our trial are:. ...

Editors Note: Commentary based on Hemnes AR, Trammell AW, Archer SL et al.A Peripeheral Blood Signature of Vasodilator-Responsive Pulmonary Arterial Hypertension. Circulation 2014;.114.013317. [Epub ahead of print].. It has long been noted that there is a small group of patients with idiopathic pulmonary arterial hypertension who have a marked improvement in their hemodynamics when given vasodilators acutely such as nitric oxide. These so-called vasodilator responders can often be successfully treated with calcium channel blocker therapy, as opposed to the great majority of idiopathic pulmonary arterial hypertension patients who do not have such an improvement and are generally treated with standard pulmonary arterial hypertension medications, e.g. phosphodiesterase 5 inhibitors, endothelin receptor antagonists and prostaglandins. We hypothesized that there is a different molecular etiology of idiopathic pulmonary arterial hypertension in patients who have this vasodilator response compared ...
BACKGROUND: In a phase 2 trial, selexipag, an oral selective IP prostacyclin-receptor agonist, was shown to be beneficial in the treatment of pulmonary arterial hypertension.. METHODS: In this event-driven, phase 3, randomized, double-blind, placebo-controlled trial, we randomly assigned 1156 patients with pulmonary arterial hypertension to receive placebo or selexipag in individualized doses (maximum dose, 1600 μg twice daily). Patients were eligible for enrollment if they were not receiving treatment for pulmonary arterial hypertension or if they were receiving a stable dose of an endothelin-receptor antagonist, a phosphodiesterase type 5 inhibitor, or both. The primary end point was a composite of death from any cause or a complication related to pulmonary arterial hypertension up to the end of the treatment period (defined for each patient as 7 days after the date of the last intake of selexipag or placebo).. RESULTS: A primary end-point event occurred in 397 patients--41.6% of those in the ...

Rationale and objectives Schistosomiasis is the world-wide leading cause of pulmonary arterial hypertension (PAH) and is particularly prevalent in developing countries. More than 80% of patients with familial PAH in the western-world have a mutation in bone morphogenetic protein type-II receptor (BMPR-II), which is a member of the transforming growth receptor-beta (TGF-b) superfamily and is important in cell proliferation and differentiation. The aim of the study was to determine if mice with a heterozygous null mutation in BMPR-II are more susceptible to pulmonary vascular remodelling induced by S. mansoni infection, compared with wild-type littermates.. ...
Germline mutations in the gene encoding for bone morphogenic receptor-2 (BMPR2) can cause pulmonary arterial hypertension (PAH). Molecular genetic diagnosis and counseling is currently available but not broadly implemented due to poor translation in direct clinical benefit.. We aim to investigate the influence of BMPR2 mutation on clinical outcome in PAH and selected parameters of long-term transthoracic echocardiography (TTE) and cardiopulmonary exercise test (CPET) follow-up in heritable PAH (HPAH) patient relatives.. BMPR2 mutation screening was performed in 124 sporadic or familial idiopathic PAH patients. Clinical, functional, hemodynamic parameters and outcome were compared in 23 BMPR2 mutation carriers and 101 noncarriers. Predictive screening was carried out in 53 HPAH relatives. TTE and CPET were performed repeatedly in 18 carriers and 15 noncarriers HPAH patient relatives, respectively.. As compared with noncarriers, BMPR2 mutation carriers were younger at diagnosis, had higher mean ...

Pulmonary Arterial Hypertension (or PAH) is caused when high blood pressure develops within the pulmonary artery, the main thoroughfare of the lungs.
The exact cause of PPH is unknown. Research has linked primary pulmonary hypertension to genetic or familial predisposition. Researchers believe the blood vessels are particularly sensitive to certain internal or external factors, and constrict, or narrow, when exposed to these factors, such as an immune system factor, or sensitivity to drugs or other chemicals.. Secondary pulmonary hypertension occurs as a result of the effects of other conditions which may include diseases of the heart or lungs, a blood clot in the lungs, or a condition called scleroderma.. ...

Arena Pharmaceuticals has completed enrollment in its Phase 2 trial evaluating ralinepag for the treatment of pulmonary arterial hypertension (PAH).
Pulmonary arterial hypertension (PAH) is a devastating cardiopulmonary disorder with significant morbidity and mortality in patients with various lung and heart diseases. PAH is characterized by vascular obstruction which leads to a sustained increased pulmonary vascular resistance, vascular remodeling, and right ventricular hypertrophy and failure. Limited PAH therapies indicate that novel approaches are urgently needed for the treatment of PAH. Nuclear factor-κB (NF-κB) has been shown to play an important role in different cardiac pathologies; however, the role of NF-κB remains limited in the setting of PAH. Here, we investigated whether NF-κB inhibition in the lungs using Club (Clara) cell-10 promoter driving IκBα mutant had any effect in monocrotaline (MCT)-induced PAH mouse model. Our data revealed that MCT-induced PAH and right ventricular hypertrophy were associated with NF-κB activation, inflammatory response, and altered expression of bone morphogenetic protein receptor 2, ...

Pulmonary arterial hypertension (PAH) is a syndrome of dyspnea, fatigue, chest pain and syncope defined by an increase in pulmonary vascular resistance (PVR) of unknown cause. The pathobiology of PAH remains incompletely understood. The gene of the idiopathic form of PAH (IPAH) has been located on chromosome 2, and shown to present mutations of a sequence that encodes for a transforming growth factor receptor, bone morphogenenetic protein receptor 2 (BMPR2). Severe pulmonary hypertension is associated with an increased expression of the angiogenic factor, angiopoietin-1, which shuts off the expression of BMPR1A, a transmembrane protein necessary for BMPR2 signalling, and thereby causes pulmonary artery smooth muscle cell proliferation. Additional biological abnormalities have been identified at all pulmonary arterial wall compartments of PAH patients. The endothelium produces an excess of endo-thelin, a potent vasoconstrictor and mitogenic mediator, while synthesis and release of antagonistic ...

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 ...

The pulmonary arterial hypertension (PAH) patients have high rate of mortality due to right ventricle (or ventricular) (RV) failures. A lot of research work is being carried out in the area, however no treatment is available that could contrast the rise in mortality rates in PAH patients. β1-adrenoceptor blockers (β-blockers, BB) reduced mortality in left heart failure, but they do not explored much at clinical level. Recent studies suggest β-blockers might be beneficial in PAH; however the mechanisms remain unknown. The present review article would put light on all these aspects of PAH along with latest ways for the management of PAH.. ...

Background: In this study we developed a new specific gene panel for pulmonary arterial hypertension (PAH) including major disease genes and further candidates.. Methods: We assessed 37 patients with invasively confirmed PAH and 5 relatives of affected patients for genetic testing. A new PAH-specific gene panel was designed using next generation sequencing including 12 known disease genes and 17 further candidates. Any potential pathogenic variants were reassessed by Sanger sequencing.. Results:Twenty-two of the 37 patients (59%) had a mutation in BMPR2, ALK1, ENG or EIF2AK4 genes identified by panel and Sanger sequencing. In addition, 12 unclassified variants were identified in 7 genes (known and candidate genes). A sensitivity of 100% was met after quality parameters were adjusted. Specificity increased to 100% when Sanger technique was applied as a routine validation.. Conclusions:The new PAH-specific gene panel developed in this study allowed for the first time the assessment of all known ...
Disease Overview Pulmonary arterial hypertension is one of a group of rare and life-threatening diseases collectively known as pulmonary hypertension (PH)....
Pulmonary arterial hypertension (PAH) is the leading cause of death in systemic sclerosis (SSc). Annual screening with echocardiogram (ECHO) is recommended. We present the methodological aspects of a PAH screening programme in a large Australian SSc cohort, the epidemiology of SSc-PAH in this cohort, and an evaluation of factors influencing physician adherence to PAH screening guidelines. Patient characteristics and results of PAH screening were determined in all patients enrolled in a SSc longitudinal cohort study. Adherence to PAH screening guidelines was assessed by a survey of Australian rheumatologists. Summary statistics, chi-square tests, univariate and multivariable logistic regression were used to determine the associations of risk factors with PAH. Among 1636 patients with SSc, 194 (11.9%) had PAH proven by right-heart catheter. Of these, 160 were detected by screening. The annual incidence of PAH was 1.4%. Patients with PAH diagnosed on subsequent screens, compared with patients in whom PAH

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. ...

Idiopathic pulmonary arterial hypertension (IPAH) is a rare and progressive disease. Several processes are believed to lead to the fatal progressive pulmonary arterial narrowing seen in IPAH including vasoconstriction, cellular proliferation inflammation, vascular remodeling, abnormalities in the lung matrix, and in situ thrombosis. Nitric oxide (NO) produced by NO synthases (NOS) is a potent vasodilator and plays important roles in many other processes including platelet function. Reduced NO levels in patients with IPAH are known to contribute to the development of pulmonary hypertension and its complications. Platelet defects have been implied in IPAH, but original research supporting this hypothesis has been limited. Normal platelets are known to have NOS activity, but little is known about NOS expression and NO production by platelets in patients with IPAH. Here we characterized the phenotype of the platelets in IPAH and show a defect in their ability to be activated in vitro by thrombin ...
This study has demonstrated that deficiency of BMPR-II increases susceptibility to PAH induced by serotonin in mice. Although the pulmonary vascular phenotype of BMPR2+/− and wild-type littermates was similar under normoxic or chronic hypoxic conditions, infusion of serotonin increased RVSP, RVH, and pulmonary vascular remodeling in BMPR2+/− mice compared with controls. These data provide the first evidence for cross-talk between the BMP and serotonin pathways, both key systems implicated in the pathogenesis of pulmonary hypertension. Serotonin infusion was associated with a reduction in lung Smad1/5 activation in hypoxic mice. Serotonin inhibited BMP signaling in PASMCs, as evidenced by inhibition of Smad1/5 phosphorylation and inhibition of Id3 transcription. Furthermore, PASMCs isolated from BMPR2+/− mice exhibited a heightened DNA synthesis to serotonin and increased activation of ERK1/2 via O·−2. Moreover, we found that pulmonary, but not systemic, arteries from BMPR2+/− mice ...
Pulmonary arterial hypertension (PAH) is characterized by obstruction of pre-capillary pulmonary arteries, which leads to sustained elevation of pulmonary arterial pressure. Identifying those at risk through early interventions, such as genetic testing, may mitigate disease course. Current practice guidelines recommend genetic counseling and offering genetic testing to individuals with heritable PAH, idiopathic PAH, and their family members. However, it is unclear if PAH specialists follow these recommendations. Thus, our research objective was to determine PAH specialists knowledge, utilization, and perceptions about genetic counseling and genetic testing. A survey was designed and distributed to PAH specialists who primarily work in the USA to assess their knowledge, practices, and attitudes about the genetics of PAH. Participants responses were analyzed using parametric and non-parametric statistics and groups were compared using the Wilcoxon rank sum test. PAH specialists had low perceived and

In patients with pulmonary arterial hypertension (PAH) combination therapy with intravenous PG12 may lead to greater disease burden, finds study.
Background: The majority of patients with idiopathic pulmonary arterial hypertension (IPAH) in functional classes II and III are currently being treated with non-parenteral therapies, including endothelin receptor antagonists (ERA), phosphodiesterase (PDE)-5 inhibitors, inhaled iloprost or combinations of these substances. If these treatments fail, current guidelines recommend the addition of parenteral prostanoid therapy. There is, however, limited evidence for the efficacy of parenteral prostanoids when added to combinations of non-parenteral therapies. Methods: In this retrospective, multicentre study we collected data from consecutive IPAH patients receiving intravenous iloprost in addition to optimized non-parenteral therapy between Jan 2002 and Dec 2009. Analyses included 6 min walk distance (6MWD), functional class, need for transplantation, and survival. Results: During the observation period, 50 patients were treated with intravenous iloprost in addition to non-parenteral therapy; 44% ...

It remains controversial whether immunosuppressive therapy is useful for PAH associated with CTD (PAH-CTD). The Dana Point algorithm does not refer such treatments in patients with PAH-CTD due to the lack of evidence. However, some case reports have shown the potential efficacy of immunosuppression for PAH-CTD. Here we report five cases of PAH-CTD treated with corticosteroids and discuss the current management of PAH-CTD with immunosuppressive ...
... (PAH) is a progressive condition that affects the heart and lungs. It is characterized by abnormally high blood pressure (hypertension) in the pulmonary artery, the blood vessel that carries blood from the heart to the lungs. The most common signs and symptoms are shortness of breath (dyspnea) during exertion and fainting spells. As the condition worsens, people can experience dizziness, swelling (edema) of the ankles or legs, chest pain, and a racing pulse. Most cases of PAH occur in individuals with no family history of the disorder. Although some cases are due to mutations in the BMPR2 gene and inherited in an autosomal dominant pattern, a gene mutation has not yet been identified in most individuals. When PAH is inherited from an affected relative it is called "familial" PAH. Cases with no identifiable cause may be referred to as "idiopathic" PAH. PAH can also occur secondary to an underlying disorder such as connective tissue diseases, HIV infection, chronic ...
