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.
Receptors for ACTIVINS are membrane protein kinases belonging to the family of PROTEIN-SERINE-THREONINE KINASES, thus also named activin receptor-like kinases (ALK's). Activin receptors also bind TRANSFORMING GROWTH FACTOR BETA. As those transmembrane receptors of the TGF-beta superfamily (RECEPTORS, TRANSFORMING GROWTH FACTOR BETA), ALK's consist of two different but related protein kinases, Type I and Type II. Activins initiate cellular signal transduction by first binding to the type II receptors (ACTIVIN RECEPTORS, TYPE II ) which then recruit and phosphorylate the type I receptors (ACTIVIN RECEPTORS, TYPE I ) with subsequent activation of the type I kinase activity.
Activins are produced in the pituitary, gonads, and other tissues. By acting locally, they stimulate pituitary FSH secretion and have diverse effects on cell differentiation and embryonic development. Activins are glycoproteins that are hetero- or homodimers of INHIBIN-BETA SUBUNITS.
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).
A growth differentiation factor that is a potent inhibitor of SKELETAL MUSCLE growth. It may play a role in the regulation of MYOGENESIS and in muscle maintenance during adulthood.
Cell-surface proteins that bind transforming growth factor beta and trigger changes influencing the behavior of cells. Two types of transforming growth factor receptors have been recognized. They differ in affinity for different members of the transforming growth factor beta family and in cellular mechanisms of action.
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.
Glycoproteins that inhibit pituitary FOLLICLE STIMULATING HORMONE secretion. Inhibins are secreted by the Sertoli cells of the testes, the granulosa cells of the ovarian follicles, the placenta, and other tissues. Inhibins and ACTIVINS are modulators of FOLLICLE STIMULATING HORMONE secretions; both groups belong to the TGF-beta superfamily, as the TRANSFORMING GROWTH FACTOR BETA. Inhibins consist of a disulfide-linked heterodimer with a unique alpha linked to either a beta A or a beta B subunit to form inhibin A or inhibin B, respectively
They are glycopeptides and subunits in INHIBINS and ACTIVINS. Inhibins and activins belong to the transforming growth factor beta superfamily.
A broadly distributed protein that binds directly to ACTIVINS. It functions as an activin antagonist, inhibits FOLLICLE STIMULATING HORMONE secretion, regulates CELL DIFFERENTIATION, and plays an important role in embryogenesis. Follistatin is a single glycosylated polypeptide chain of approximately 37-kDa and is not a member of the inhibin family (INHIBINS). Follistatin also binds and neutralizes many members of the TRANSFORMING GROWTH FACTOR BETA family.
A subtype of bone morphogenetic protein receptors with low affinity for BONE MORPHOGENETIC PROTEINS. They are constitutively active PROTEIN-SERINE-THREONINE KINASES that can interact with and phosphorylate TYPE I BONE MORPHOGENETIC PROTEIN RECEPTORS.
Cell surface receptors that bind growth or trophic factors with high affinity, triggering intracellular responses which influence the growth, differentiation, or survival of cells.
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.
A group of enzymes that catalyzes the phosphorylation of serine or threonine residues in proteins, with ATP or other nucleotides as phosphate donors.
A receptor-regulated smad protein that undergoes PHOSPHORYLATION by ACTIVIN RECEPTORS, TYPE I. It regulates TRANSFORMING GROWTH FACTOR BETA and ACTIVIN signaling.
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.
A family of proteins that are involved in the translocation of signals from TGF-BETA RECEPTORS; BONE MORPHOGENETIC PROTEIN RECEPTORS; and other surface receptors to the CELL NUCLEUS. 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.
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.
Cell surface receptors that are specific for INTERLEUKIN-1. Included under this heading are signaling receptors, non-signaling receptors and accessory proteins required for receptor signaling. Signaling from interleukin-1 receptors occurs via interaction with SIGNAL TRANSDUCING ADAPTOR PROTEINS such as MYELOID DIFFERENTIATION FACTOR 88.
A tumor necrosis factor receptor subtype that is expressed primarily in IMMUNE SYSTEM cells. It has specificity for membrane-bound form of TUMOR NECROSIS FACTORS and mediates intracellular-signaling through TNF RECEPTOR ASSOCIATED FACTORS.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

Lack of regulation in the heart forming region of avian embryos. (1/298)

The ability to regenerate a heart after ablation of cardiogenic mesoderm has been demonstrated in early stage fish and amphibian embryos but this type of regulation of the heart field has not been seen in avians or mammals. The regulative potential of the cardiogenic mesoderm was examined in avian embryos and related to the spatial expression of genes implicated in early cardiogenesis. With the identification of early cardiac regulators such as bmp-2 and nkx-2.5, it is now possible to reconcile classical embryological studies with molecular mechanisms of cardiac lineage determination in vivo. The most anterior lateral embryonic cells were identified as the region that becomes the heart and removal of all or any subset of these cells resulted in the loss of corresponding cardiac structures. In addition, removal of the lateral heart forming mesoderm while leaving the lateral endoderm intact also results in loss of cardiac structures. Thus the medial anterior mesoderm cannot be recruited into the heart lineage in vivo even in the presence of potentially cardiac inducing endoderm. In situ analysis demonstrated that genes involved in early events of cardiogenesis such as bone morphogenetic protein 2 (bmp-2) and nkx-2.5 are expressed coincidentally with the mapped far lateral heart forming region. The activin type IIa receptor (actR-IIa) is a potential mediator of BMP signaling since it is expressed throughout the anterior mesoderm with the highest level of expression occurring in the lateral prospective heart cells. The posterior boundary of actR-IIa is consistent with the posterior boundary of nkx-2.5 expression, supporting a model whereby ActR-IIa is involved in restricting the heart forming region to an anterior subset of lateral cells exposed to BMP-2. Analysis of the cardiogenic potential of the lateral plate mesoderm posterior to nkx-2.5 and actR-IIa expression demonstrated that these cells are not cardiogenic in vitro and that removal of these cells from the embryo does not result in loss of heart tissue in vivo. Thus, the region of the avian embryo that will become the heart is defined medially, laterally, and posteriorly by nkx-2.5 gene expression. Removal of all or part of the nkx-2.5 expressing region results in the loss of corresponding heart structures, demonstrating the inability of the chick embryo to regenerate cardiac tissue in vivo at stages after nkx-2.5 expression is initiated.  (+info)

Identification of two amino acids in activin A that are important for biological activity and binding to the activin type II receptors. (2/298)

Activins are members of the transforming growth factor-beta family of growth and differentiation factors. In this paper, we report the results of a structure-function analysis of activin A. The primary targets for directed mutagenesis were charged, individual amino acids located in accessible domains of the protein, concentrating on those that differ from transforming growth factor-beta2, the x-ray crystal structure of which is known. Based on the activities of the recombinant activin mutants in two bioassays, 4 out of 39 mutant proteins (D27K, K102A, K102E, and K102R) produced in a vaccinia virus system were selected for further investigation. After production in insect cells and purification of these four mutants to homogeneity, they were studied in bioassays and in cross-linking experiments involving transfected receptor combinations. Mutant D27K has a 2-fold higher specific bio-activity and binding affinity to an ActRIIA/ALK-4 activin receptor complex than wild type activin, whereas mutant K102E had no detectable biological activity and did not bind to any of the activin receptors. Mutant K102R and wild type activin bound to all the activin receptor combinations tested and were equipotent in bioassays. Our results with the Lys-102 mutants indicate that the positive charge of amino acid 102 is important for biological activity and type II receptor binding of activins.  (+info)

Control of digit formation by activin signalling. (3/298)

Major advances in the genetics of vertebrate limb development have been obtained in recent years. However, the nature of the signals which trigger differentiation of the mesoderm to form the limb skeleton remains elusive. Previously, we have obtained evidence for a role of TGFbeta2 in digit formation. Here, we show that activins A and B and/or AB are also signals involved in digit skeletogenesis. activin betaA gene expression correlates with the initiation of digit chondrogenesis while activin betaB is expressed coincidently with the formation of the last phalanx of each digit. Exogenous administration of activins A, B or AB into the interdigital regions induces the formation of extra digits. follistatin, a natural antagonist of activins, is expressed, under the control of activin, peripherally to the digit chondrogenic aggregates marking the prospective tendinous blastemas. Exogenous application of follistatin blocks physiological and activin-induced digit formation. Evidence for a close interaction between activins and other signalling molecules, such as BMPs and FGFs, operating at the distal tip of the limb at these stages is also provided. Chondrogenesis by activins is mediated by BMPs through the regulation of the BMP receptor bmpR-1b and in turn activin expression is upregulated by BMP signalling. In addition, AER hyperactivity secondary to Wnt3A misexpression or local administration of FGFs, inhibits activin expression. In correlation with the restricted expression of activins in the course of digit formation, neither activin nor follistatin treatment affects the development of the skeletal components of the stylopod or zeugopod indicating that the formation of the limb skeleton is regulated by segment-specific chondrogenic signals.  (+info)

Impaired differentiation of endocrine and exocrine cells of the pancreas in transgenic mouse expressing the truncated type II activin receptor. (4/298)

Activin A is expressed in endocrine precursor cells of the fetal pancreatic anlage. To determine the physiological significance of activins in the pancreas, a transgenic mouse line expressing the truncated type II activin receptor under the control of beta-actin promoter was developed. Histological analyses of the pancreas revealed that the pancreatic islets of the transgenic mouse were small in size and were located mainly along the pancreatic ducts. Immunoreactive insulin was detected in islets, some acinar cells, and in some epithelial cells in the duct. In addition, there were abnormal endocrine cells outside the islets. The shape and the size of the endocrine cells varied and some of them were larger than islets. These cells expressed immunoreactive insulin and glucagon. In the exocrine portion, there were morphologically abnormal exocrine cells, which did not form a typical acinar structure. The cells lacked spatial polarity characteristics of acinar cells but expressed immunoreactive amylase, which was distributed diffusely in the cytoplasm. Plasma glucose concentration was normal in the transgenic mouse before and after the administration of glucose. The insulin content of the pancreas in transgenic and normal mice was nearly identical. These results suggest that activins or related ligands regulate the differentiation of the pancreatic endocrine and exocrine cells.  (+info)

The type II activin receptors are essential for egg cylinder growth, gastrulation, and rostral head development in mice. (5/298)

The type II activin receptors, ActRIIA and ActRIIB, have been shown to play critical roles in axial patterning and organ development in mice. To investigate whether their function is required for mesoderm formation and gastrulation as implicated in Xenopus studies, we generated mice carrying both receptor mutations by interbreeding the ActRIIA and ActRIIB knockout mutants. We found that embryos homozygous for both receptor mutations were growth arrested at the egg cylinder stage and did not form mesoderm. Further analyses revealed that ActRIIA(-/-)ActRIIB(+/-) and about 15% of the ActRIIA(-/-) embryos failed to form an elongated primitive streak, resulting in severe disruption of mesoderm formation in the embryo proper. Interestingly, we observed similar gastrulation defects in ActRIIA(-/-)nodal(+/-) double mutants, which, if they developed beyond the gastrulation stage, displayed rostral head defects and cyclopia. These results provide genetic evidence that type II activin receptors are required for egg cylinder growth, primitive streak formation, and rostral head development in mice.  (+info)

Activin stimulation of zebrafish oocyte maturation in vitro and its potential role in mediating gonadotropin-induced oocyte maturation. (6/298)

Activin plays important roles in the regulation of vertebrate reproduction. Using zebrafish, Danio rerio, as a model, the present study aimed at investigating the role of activin in the regulation of final oocyte maturation. Administration of recombinant goldfish activin B significantly increased the rate of oocyte maturation in vitro in a dose- and time-dependent manner. The effect of activin seemed to be additive to the effects of gonadotropin (hCG) and 17alpha,20beta-dihydroxyprogesterone, a potent maturation-inducing hormone in teleosts. The specificity of the activin action was confirmed by coincubation with recombinant human follistatin, which completely abolished the stimulatory effect of activin B. Interestingly, follistatin also significantly inhibited hCG-induced oocyte maturation, suggesting that endogenous activin may be a downstream mediator of gonadotropin actions. No effect of activin B was observed in the presence of actinomycin D, indicating that the action of activin may involve changes in transcriptional activity. These results, together with the demonstration that activin and its type II receptor are expressed in the zebrafish ovary, strongly suggest a paracrine/autocrine role for activin in the controlling of final oocyte maturation.  (+info)

Characterization of bone morphogenetic protein-6 signaling pathways in osteoblast differentiation. (7/298)

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)

Mouse Lefty2 and zebrafish antivin are feedback inhibitors of nodal signaling during vertebrate gastrulation. (8/298)

Mammalian lefty and zebrafish antivin form a subgroup of the TGF beta superfamily. We report that mouse mutants for lefty2 have an expanded primitive streak and form excess mesoderm, a phenotype opposite to that of mutants for the TGF beta gene nodal. Analogously, overexpression of Antivin or Lefty2 in zebrafish embryos blocks head and trunk mesoderm formation, a phenotype identical to that of mutants caused by loss of Nodal signaling. The lefty2 mutant phenotype is partially suppressed by heterozygosity for nodal. Similarly, the effects of Antivin and Lefty2 can be suppressed by overexpression of the nodal-related genes cyclops and squint or the extracellular domain of ActRIIB. Expression of antivin is dependent on Nodal signaling, revealing a feedback loop wherein Nodal signals induce their antagonists Lefty2 and Antivin to restrict Nodal signaling during gastrulation.  (+info)

The resulting malformations include atrial and ventricular septal defects, right-sided morphology of the left atrium and left lung, and spleen hypoplasia.

The Role of ActRIIB Signaling and Muscle Growth. Muscle growth is regulated by proteins in the TGF-? protein superfamily that serve as on or off switches for muscle production. Several molecules including GDF-8 interact with the ActRIIB receptor and send an off signal to stop muscle production. In the absence of these off switch molecules that signal through the ActRIIB receptor, muscle mass increases dramatically. In nature, this effect has been observed in numerous species, particularly in animals that have been bred for increased musculature and strength. For example, Belgian Blue cattle lack the gene for GDF-8, which is one of several molecules that activate the ActRIIB receptor. A deficiency of this protein results in cattle with tremendously developed musculature and strength. Similar effects have been observed in other species, including rodents, dogs and even humans.. Treatment with ACE-031 Builds Skeletal Muscle. Treatment with ACE-031 promotes muscle growth by inhibiting ...

In the present experiments, AP has been measured in Alk1+/− and in Alk1+/+ mice by both tail-cuff and radiotelemetry methods. We have used both methods to measure AP because movement restriction necessary for tail-cuff measurement can modify vasoactive responses, especially when the sympathetic nervous system is involved, and because acute (minutes) effects can be difficult to assess by the tail-cuff method. Besides, both acute and prolonged effects of the vasoactive substances have been recorded because the acute and the long-standing consequences of inhibiting or stimulating these regulatory pathways can be different (Emanueli et al., 1997). Measurements of AP by the tail-cuff method and by telemetry showed consistently higher SAP in Alk1+/− than in Alk1+/+ mice, with no significant differences in HR. It should be noted that arterial hypertension has not been reported as a common sign in individuals with hereditary hemorrhagic telangiectasia type 2, a fact that can be explained by the ...

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 ...
ACVRL1 (activin receptor-like kinase 1, or ALK1) gene encodes type I cell-surface receptor on the TGF β signaling pathway , which is consist of a glycine- and serine-rich region (GS domain), serine-threonine kinase sub-domains, and a short C-terminal tail [36]. Mutations in ACVRL1 are responsible for HHT2, a disease manifesting as fragile vessels, capillary overgrowth, and numerous AVMs [37]. In HHT patients, the majority of vessels are normal, however the ACVRL1 mutations could lead to abnormal angiogenetic responses and formation of anormalous arteriovenous connections, ranging from mucomembranous telangiectases to large arteriovenous malformations that can occur in every organ such as lungs, liver and brain [12, 38]. ENG or ACVRL1 mutations were found in more than 80 % of all HHT patients. One to two percent of cases 127 have mutations in SMAD4 [39]. This gene encodes smad proteins which is a member of signal transduction proteins in Smad family. The proteins are phosphorylated by ...
HHT is a genetically heterogeneous disease with at least three causative genes [9-15]. 15% of clinically diagnosed HHT cases cannot be explained by mutations in the coding regions or exon/intron junctions of ACVRL1, ENG, or SMAD4[19, 20]). Yet in some families, linkage data suggests ACVRL1 or ENG to be the causative gene. Therefore, non-coding regions may play a role in the disease. However, previously described mutations in ENG were located only on the coding regions and exon-intron junctions of the gene [29, 30]. So far, no 5UTR mutations or deep intronic mutations have been described. ENG promoter activity was found to be within the upstream 400 bp region from the TIS, and an area near the transcription initiation site of ENG was determined to be essential for promoter function [21, 31]. We therefore chose this critical region to analyze in our unexplained HHT cases. We have identified a 5UTR mutation (c.-127C , T) in 3 unrelated probands, 2 of which had family members evaluated for ...
Endoglin is a transmembrane glycoprotein 633 residues in length expressed at the surface of endothelial cells as a disulphide-linked homodimer; the specific cysteine residues involved in endoglin dimerization are unknown. Mutations in the coding region of the endoglin gene are responsible for hereditary haemorrhagic telangiectasia type 1 (HHT1), a dominantly inherited vascular disorder. Many of these mutations, if translated, would lead to truncated forms of the protein. It is therefore of interest to assess the protein expression of different truncated forms of endoglin. Infections in vitro or in vivo with recombinant vaccinia virus, as well as transient transfections with expression vectors, were used to express normal and truncated forms of endoglin. Truncated mutants could be classified into three different groups: (1) those that did not produce stable transcripts; (2) those that produced stable transcripts but did not secrete the protein; and (3) those that secreted a soluble dimeric ...
According to scientific study that has been conducted on animal test subjects, the primary purpose of Myostatin HMP is to act as an inhibitor to myostatin.. Myostatin has been determined to be a secreted growth differentiation factor, meaning that it is part of a subfamily of proteins that are part of the transforming growth factor beta superfamily that have functions chiefly associated with development. Specifically, it is part of the TGF beta protein family that blocks the process of muscle differentiation and growth in myogenesis, which is the process in which muscular tissue is formed particularly during embryonic development. The peptide is chiefly produced via skeletal muscle cells. It also circulates throughout the blood and is known to act on muscle tissue by binding a cell-bound receptor that is known as the activin type II receptor..

The cysteine residue is highly conserved and there is a large physicochemical difference between cysteine and phenylalanine. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individuals affected with hereditary haemorrhagic telangiectasia or clinical features of this disease (PMID: 12114496, Invitae). Experimental studies have shown that this missense variant showed improper cellular localization (PMID: 23124896). This variant disrupts the p.Cys344 amino acid residue in ACVRL1. Other variant(s) that disrupt this residue have been observed in affected individuals (PMID: 16470787, 18673552, 16752392, 19767588, 10767348, 15880681), suggesting that it is a clinically significant residue. As a result, variants that disrupt this residue are likely to be causative of disease. In summary, the ...
On ligand binding, forms a receptor complex consisting of two type II and two type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors which autophosphorylate, then bind and activate SMAD transcriptional regulators. Receptor for activin A, activin B and inhibin A. Mediates induction of adipogenesis by GDF6.
Using positional cloning and candidate gene testing, we have identified the molecular basis for the cranial vessel dilation observed in vbg mutants. We meiotically mapped the vbg locus to an interval of 0.035 cM on LG23 and established a physical contig across this region containing the acvrl1 gene. The vbgy6 allele of acvrl1 contains a missense mutation in the C-terminal serine/threonine kinase domain, whereas the vbgft09e allele contains a nonsense mutation in the N-terminal ligand binding domain. The former polymorphism exhibited no recombination in 4256 vbgy6 mutants (8512 informative meioses). Furthermore, injection of antisense, morpholino-modified oligonucleotides specific to acvrl1 phenocopies the vascular defect seen in vbg mutants. Finally, at 40 hpf, when the vbg mutant phenotype is first detectable, acvrl1 mRNA is expressed predominantly in vessels that are consistently dilated in vbg mutants: the first aortic arch, internal carotid artery/caudal division, and basal communicating ...
This sequence change replaces serine with phenylalanine at codon 305 of the ACVRL1 protein (p.Ser305Phe). The serine residue is highly conserved and there is a large physicochemical difference between serine and phenylalanine. This variant is not present in population databases (ExAC no frequency). This variant has been observed in to segregate in a family affected with hereditary hemorrhagic telangiectasia (Invitae) and has been observed in unrelated individuals affected with this disease (PMID: 17384219, 29171923, Invitae). ClinVar contains an entry for this variant (Variation ID: 439382). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. The observation of one or more missense substitutions at this codon (p.Ser305Phe and p.Ser305Pro) in ...
In a recent study (Zhou et al., 2010), the authors defined the mechanism by which ActRIIB and its ligands regulate cachexia by studying multiple mouse models of cancer. They also investigated the potential therapeutic effects on cancer cachexia of blocking signaling through the ActRIIB signaling pathway. To antagonize the ActRIIB pathway, they engineered a decoy receptor containing the extracellular portion of human ActRIIB fused to the Fc region of IgG2, designated sActRIIB (soluble ActRIIB-Fc). The authors administered this decoy receptor to antagonize the ActRIIB pathway in four distinct mouse models of lethal cancer cachexia: colon26 (C26) murine adenocarcinoma-bearing mice, inhibin-α knockout mice (which develop gonadal tumors) and immunocompromised nude mice bearing either human G361 melanoma or TOV-21G ovarian carcinoma xenografts. By testing diverse models of cancer cachexia with tumors of distinct origin, the authors minimized the possibility that the tumor site or type would influence ...

We investigated the erythroid response to either erythropoietin or RAP-011, a murinized ortholog of sotatercept, in C57BL/6 mice and in hepcidin antimicrobial peptide 1 over expressing mice. Sotatercept, a soluble, activin receptor type IIA ligand trap, is currently being evaluated for the treatment of anemias associated with chronic renal disease, myelodysplastic syndrome, β-thalassemia, and Diamond Blackfan anemia and acts by inhibiting signaling downstream of activin and other Transforming Growth Factor-β superfamily members. We found that erythropoietin and RAP-011 ...
The proposed study aims to understand the factors that influence screening behaviors of adults with hereditary hemorrhagic telangiectasia (HHT). HHT is a chronic condition, but with early diagnosis followed by adherence to recommended screening guidelines, the major complications of this disorder can be avoided and disability or even death can be prevented. Yet, it has come to the attention of healthcare professionals that the recommended screening is not commonly followed by individuals with HHT, even when the risk of serious complications is known. Nonadherence to screening recommendations is not unique to HHT. It is rather common across chronic conditions, and genetic diseases, such as HHT, are no exception. However, HHT may have an added barrier to screening and treatment adherence in that it is a rare and underdiagnosed condition. Inadequate knowledge of healthcare providers may be a serious barrier to prevention, diagnosis, and treatment. The Health Belief Model (HBM) can be used to frame ...
BACKGROUND: There are very few studies about general quality of life parameters, standards for the description of health status and comparison with general population data on patients with Hereditary hemorrhagic telangiectasia (HHT), a rare disease in which epistaxis is a cardinal symptom. PURPOSE: To assess the quality of life in a population of Spanish patients with HHT and compare it with the general population. DESIGN AND METHODS: Between January 1(st) 2005 and December 31(st) 2013, 187 adult patients diagnosed with HHT who were admitted to the HHT Unit of the Hospital Sierrallana, completed on their first visit, the EuroQol 5D-3L (five dimensions and three levels) quality of life descriptive test and the visual analog scale (VAS ...

Activin-A and activin-B, members of the TGF-β superfamily, are regulators of reproductive functions, inflammation and wound healing. These dimeric molecules regulate various cellular activities such as proliferation, migration and suvival. Malignant mesothelioma is an asbestos exposure related tumor affecting mainly pleura and it usually has a dismal prognosis. Here, we demonstrate that both activin-A and -B are abundantly expressed in mesothelioma tumor tissue as well as in cultured primary and established mesothelioma cells. Migratory and invasive mesothelioma cells were also found to have attenuated activation of the Smad2/3 pathway in response to activins. Migration and invasive growth of the cells in three-dimentional matrix was prevented by inhibition of activin activity using a soluble activin receptor 2B (sActR2B-Fc). This was associated with decreased ERK activity. Furthermore, migration and invasive growth was significantly inhibited by blocking ERK phosphorylation. Mesothelioma ...
Cell-cell contacts are fundamental to multicellular organisms and are subject to exquisite levels of control. Human RPTPmu is a type IIB receptor protein tyrosine phosphatase that both forms an adhesive contact itself and is involved in regulating adhesion by dephosphorylating components of cadherin-catenin complexes. Here we describe a 3.1 angstrom crystal structure of the RPTPmu ectodomain that forms a homophilic trans (antiparallel) dimer with an extended and rigid architecture, matching the dimensions of adherens junctions. Cell surface expression of deletion constructs induces intercellular spacings that correlate with the ectodomain length. These data suggest that the RPTPmu ectodomain acts as a distance gauge and plays a key regulatory function, locking the phosphatase to its appropriate functional location.
The TGF-β superfamily is a large family of growth and differentiation factors that regulate a wide variety of cellular processes in many different cell types and biological contexts. Different family members regulate cell proliferation (both positively and negatively), migration, extracellular matrix elaboration, adhesion, survival and differentiation, in both developing embryos and adult organisms, ranging from worms to humans (Whitman, 1998; Massagué and Chen, 2000; Massagué et al., 2000). Aberrant signaling by TGF-β, the prototype of the family, has been implicated in a number of human diseases, including cancer, hereditary hemorrhagic telangiectasia, atherosclerosis, and fibrotic disease of the kidney, liver, and lung (Blobe et al., 2000). In addition, low levels of TGF-β signaling have been implicated in compromised wound healing, and inappropriately high levels of TGF-β signaling are associated with excessive scarring (Roberts and Sporn, 1993).. The mechanism of signaling by TGF-β ...
This gene encodes a type I cell-surface receptor for the TGF-beta superfamily of ligands. It shares with other type I receptors a high degree of similarity in serine-threonine kinase subdomains, a glycine- and serine-rich region (called the GS domain) preceding the kinase domain, and a short C-terminal tail. The encoded protein, sometimes termed ALK1, shares similar domain structures with other closely related ALK or activin receptor-like kinase proteins that form a subfamily of receptor serine/threonine kinases. Mutations in this gene are associated with hemorrhagic telangiectasia type 2, also known as Rendu-Osler-Weber syndrome 2. [provided by RefSeq, Jul 2008 ...
Using a mix of wild-type (WT) and caveolin-2 (Cav-2) knockout along with retroviral reexpression approaches, we offer the data for the negative role of Cav-2 in regulating anti-proliferative function and signaling of changing growth matter (TGF-) in endothelial cells (ECs). evidenced by three unbiased proliferation assays: 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), cell count number, and bromodeoxyuridine incorporation and correlated with a lack of TGF-mediated upregulation of cell routine inhibitor Rabbit polyclonal to PAI-3 p27 and following Rebastinib reduced amount of the degrees of hyperphosphorylated (inactive) type of the retinoblastoma protein in Cav-2 reexpressing ECs. Mechanistically, Cav-2 inhibits anti-proliferative action of TGF- by suppressing Alk5-Smad2/3 pathway manifested by reduced magnitude and amount of TGF-induced Smad2/3 phosphorylation aswell as activation of activin receptor-like kinase-5 (Alk5)-Smad2/3 target genes plasminogen activator ...
Plans are to recruit patients with HHT from the UCSD Nasal Dysfunction Clinic. The HHT world is connected through the HHT Foundation. The Foundation is interested in VEGF inhibitors. They have carefully watched our work at UCSD for a long time and our two papers on Avastin have been circulated around the world. Those who come for our evaluation and are deemed appropriate for Bevacizumab injection will be recruited for this study. Those agreeing to participate will sign a consent form.. The treatment, regardless of participation in the proposed research, is to bring the patients to the operating room where under general anesthesia the nose is suctioned clean of blood clot, crust and secretion. The mucosa is then injected with a local anesthetic with adrenaline to reduce discomfort and to reduce bleeding. The nasal mucosa is treated with a KTP laser in our standard fashion. A 100mg of Avastin delivered in 4cc is then diluted with 4cc of normal saline to a total volume of 8cc. The dilution is made ...
BACKGROUND: Bone morphogenetic proteins (BMPs) are key regulators in the embryonic development and postnatal tissue homeostasis in all animals. Loss of function or dysregulation of BMPs results in severe diseases or even lethality. Like transforming growth factors beta (TGF-betas), activins, growth and differentiation factors (GDFs) and other members of the TGF-beta superfamily, BMPs signal by assembling two types of serine/threonine-kinase receptor chains to form a hetero-oligomeric ligand-receptor complex. BMP ligand receptor interaction is highly promiscuous, i.e. BMPs bind more than one receptor of each subtype, and a receptor bind various ligands. The activin type II receptors are of particular interest, since they bind a large number of diverse ligands. In addition they act as high-affinity receptors for activins but are also low-affinity receptors for BMPs. ActR-II and ActR-IIB therefore represent an interesting example how affinity and specificity might be generated in a promiscuous ...

Hereditary Haemorrhagic Telangiectasia This patient suffers from an inherited bleeding condition, which in this case (rarely) presented as very severe life threatening nose bleeds (epistaxis) which did not respond to radical surgery. Over a 10 year period she underwent hundreds of operations to stop the recurrent nose bleeds, which resulted in total collapse of the nose, and had little effect on the recurrent bleeding problem. Bleeding was so severe that she required an i.v. placed in the right atrium of the heart (Hickman Line) for emergency blood transfusions. She was naturally most reluctant to undergo life saving total nasal amputation, the treatment of choice, for the severity of this condition ...
