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
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
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.
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).
Myostatin
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.
Inhibins
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
Inhibin-beta Subunits
They are glycopeptides and subunits in INHIBINS and ACTIVINS. Inhibins and activins belong to the transforming growth factor beta superfamily.
Follistatin
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.
Receptors, Interleukin-1 Type I
An interleukin-1 receptor subtype that is involved in signaling cellular responses to INTERLEUKIN-1ALPHA and INTERLEUKIN-1BETA. The binding of this receptor to its ligand causes its favorable interaction with INTERLEUKIN-1 RECEPTOR ACCESSORY PROTEIN and the formation of an activated receptor complex.
Receptors, Transforming Growth Factor beta
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.
Receptors, Growth Factor
Cell surface receptors that bind growth or trophic factors with high affinity, triggering intracellular responses which influence the growth, differentiation, or survival of cells.
Smad2 Protein
A receptor-regulated smad protein that undergoes PHOSPHORYLATION by ACTIVIN RECEPTORS, TYPE I. It regulates TRANSFORMING GROWTH FACTOR BETA and ACTIVIN signaling.
Receptors, Interleukin-1
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.
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.
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.
RNA, Messenger
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.
Receptors, Tumor Necrosis Factor, Type I
A tumor necrosis factor receptor subtype that has specificity for TUMOR NECROSIS FACTOR ALPHA and LYMPHOTOXIN ALPHA. It is constitutively expressed in most tissues and is a key mediator of tumor necrosis factor signaling in the vast majority of cells. The activated receptor signals via a conserved death domain that associates with specific TNF RECEPTOR-ASSOCIATED FACTORS in the CYTOPLASM.
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.
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.
Nodal Protein
The founding member of the nodal signaling ligand family of proteins. Nodal protein was originally discovered in the region of the mouse embryo primitive streak referred to as HENSEN'S NODE. It is expressed asymmetrically on the left side in chordates and plays a critical role in the genesis of left-right asymmetry during vertebrate development.
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.
Interleukin-1 Receptor Accessory Protein
A protein that takes part in the formation of active interleukin-1 receptor complex. It binds specifically to INTERLEUKIN-1 and the INTERLEUKIN-1 RECEPTOR TYPE I at the cell surface to form a heterotrimeric complex that brings its cytoplasmic domain into contact with the cytoplasm domain of the TYPE-I INTERLEUKIN-1 RECEPTOR. Activation of intracellular signal transduction pathways from the receptor is believed to be driven by this form of cytoplasmic interaction.
Smad Proteins
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.

Mice, Knockout
Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

Crystal structure of the cytoplasmic domain of the type I TGF beta receptor in complex with FKBP12. (1/587)

Activation of the type I TGFbeta receptor (TbetaR-I) requires phosphorylation of a regulatory segment known as the GS region, located upstream of the serine/threonine kinase domain in the cytoplasmic portion of the receptor. The crystal structure of a fragment of unphosphorylated TbetaR-I, containing both the GS region and the catalytic domain, has been determined in complex with the FK506-binding protein FKBP12. TbetaR-I adopts an inactive conformation that is maintained by the unphosphorylated GS region. FKBP12 binds to the GS region of the receptor, capping the TbetaR-II phosphorylation sites and further stabilizing the inactive conformation of TbetaR-I. Certain structural features at the catalytic center of TbetaR-I are characteristic of tyrosine kinases rather than Ser/Thr kinases.  (+info)

Transforming growth factor-beta induces formation of a dithiothreitol-resistant type I/Type II receptor complex in live cells. (2/587)

Transforming growth factor-beta (TGF-beta) binds to and signals via two serine-threonine kinase receptors, the type I (TbetaRI) and type II (TbetaRII) receptors. We have used different and complementary techniques to study the physical nature and ligand dependence of the complex formed by TbetaRI and TbetaRII. Velocity centrifugation of endogenous receptors suggests that ligand-bound TbetaRI and TbetaRII form a heteromeric complex that is most likely a heterotetramer. Antibody-mediated immunofluorescence co-patching of epitope-tagged receptors provides the first evidence in live cells that TbetaRI. TbetaRII complex formation occurs at a low but measurable degree in the absence of ligand, increasing significantly after TGF-beta binding. In addition, we demonstrate that pretreatment of cells with dithiothreitol, which inhibits the binding of TGF-beta to TbetaRI, does not prevent formation of the TbetaRI.TbetaRII complex, but increases its sensitivity to detergent and prevents TGF-beta-activated TbetaRI from phosphorylating Smad3 in vitro. This indicates that either a specific conformation of the TbetaRI. TbetaRII complex, disrupted by dithiothreitol, or direct binding of TGF-beta to TbetaRI is required for signaling.  (+info)

Interaction of 5-lipoxygenase with cellular proteins. (3/587)

5-Lipoxygenase (5LO) plays a pivotal role in cellular leukotriene synthesis. To identify proteins interacting with human 5LO, we used a two-hybrid approach to screen a human lung cDNA library. From a total of 1.5 x 10(7) yeast transformants, nine independent clones representing three different proteins were isolated and found to specifically interact with 5LO. Four 1.7- to 1.8-kb clones represented a 16-kDa protein named coactosin-like protein for its significant homology with coactosin, a protein found to be associated with actin in Dictyostelium discoideum. Coactosin-like protein thus may provide a link between 5LO and the cytoskeleton. Two other yeast clones of 1.5 kb encoded transforming growth factor (TGF) type beta receptor-I-associated protein 1 partial cDNA. TGF type beta receptor-I-associated protein 1 recently has been reported to associate with the activated form of the TGF beta receptor I and may be involved in the TGF beta-induced up-regulation of 5LO expression and activity observed in HL-60 and Mono Mac 6 cells. Finally, three identical 2.1-kb clones contained the partial cDNA of a human protein with high homology to a hypothetical helicase K12H4. 8 from Caenorhabditis elegans and consequently was named DeltaK12H4. 8 homologue. Analysis of the predicted amino acid sequence revealed the presence of a RNase III motif and a double-stranded RNA binding domain, indicative of a protein of nuclear origin. The identification of these 5LO-interacting proteins provides additional approaches to studies of the cellular functions of 5LO.  (+info)

Dominant-negative Smad2 mutants inhibit activin/Vg1 signaling and disrupt axis formation in Xenopus. (4/587)

Smads are central mediators of signal transduction for the TGFbeta superfamily. However, the precise functions of Smad-mediated signaling pathways in early development are unclear. Here we demonstrate a requirement for Smad2 signaling in dorsoanterior axis formation during Xenopus development. Using two point mutations of Smad2 previously identified in colorectal carcinomas, we show that Smad2 ushers Smad4 to the nucleus to form a transcriptional activation complex with the nuclear DNA-binding protein FAST-1 and that the mutant proteins interact normally with FAST-1 but fail to recruit Smad4 into the nucleus. This mechanism of inhibition specifically restricts the dominant-negative activity of these mutants to the activin/Vg1 signaling pathway without inhibiting BMPs. Furthermore, expression of these mutants in Xenopus animal caps inhibits but does not abolish activin and Vg1 induction of mesoderm and in the embryo results in a truncated dorsoanterior axis. These studies define a mechanism through which mutations in Smad2 may block TGFbeta-dependent signaling and suggest a critical role for inductive signaling mediated by the Smad2 pathway in Xenopus organizer function.  (+info)

A short loop on the ALK-2 and ALK-4 activin receptors regulates signaling specificity but cannot account for all their effects on early Xenopus development. (5/587)

Activin, a member of the transforming growth factor beta (TGF-beta) superfamily, signals through a heteromeric complex of type I and type II serine-threonine kinase receptors. The two activin type I receptors previously identified, ALK-2 (ActR-I) and ALK-4 (ActR-IB), have distinct effects on gene expression, differentiation and morphogenesis in the Xenopus animal cap assay. ALK-4 reproduces the effects of activin treatment including the dose-dependent induction of progressively more dorso-anterior mesodermal and endodermal markers, whereas ALK-2 induces only ventral mesodermal markers and counteracts the effects of ALK-4. To identify regions of the receptors that determine signaling specificity we have generated chimeras of the constitutively active ALK-2 and ALK-4 receptors (termed ALK-2* and ALK-4*). The effects of these chimeric receptors on gene expression and morphogenetic movements implicate the loop between kinase subdomains IV and V in mediating the strong dorsal gene-inducing properties of ALK-4*; when the seven amino acids comprising this loop are transferred from ALK-4* to ALK-2*, the resulting chimeric receptor is capable of inducing the expression of dorsal-specific genes. In contrast, when the equivalent region of ALK-2* is transferred to the ALK-4* backbone it cannot effectively counteract the dorsalizing effects of ALK-4*, suggesting that other regions of type I receptors are also involved in determining signal specificity.  (+info)

TAKs, thylakoid membrane protein kinases associated with energy transduction. (6/587)

The phosphorylation of proteins within the eukaryotic photosynthetic membrane is thought to regulate a number of photosynthetic processes in land plants and algae. Both light quality and intensity influence protein kinase activity via the levels of reductants produced by the thylakoid electron transport chain. We have isolated a family of proteins called TAKs, Arabidopsis thylakoid membrane threonine kinases that phosphorylate the light harvesting complex proteins. TAK activity is enhanced by reductant and is associated with the photosynthetic reaction center II and the cytochrome b6f complex. TAKs are encoded by a gene family that has striking similarity to transforming growth factor beta receptors of metazoans. Thus thylakoid protein phosphorylation may be regulated by a cascade of reductant-controlled membrane-bound protein kinases.  (+info)

The type I serine/threonine kinase receptor ActRIA (ALK2) is required for gastrulation of the mouse embryo. (7/587)

ActRIA (or ALK2), one of the type I receptors of the transforming growth factor-beta (TGF-beta) superfamily, can bind both activin and bone morphogenetic proteins (BMPs) in conjunction with the activin and BMP type II receptors, respectively. In mice, ActRIA is expressed primarily in the extraembryonic visceral endoderm before gastrulation and later in both embryonic and extraembryonic cells during gastrulation. To elucidate its function in mouse development, we disrupted the transmembrane domain of ActRIA by gene targeting. We showed that embryos homozygous for the mutation were arrested at the early gastrulation stage, displaying abnormal visceral endoderm morphology and severe disruption of mesoderm formation. To determine in which germ layer ActRIA functions during gastrulation, we performed reciprocal chimera analyses. (1) Homozygous mutant ES cells injected into wild-type blastocysts were able to contribute to all three definitive germ layers in chimeric embryos. However, a high contribution of mutant ES cells in chimeras disrupted normal development at the early somite stage. (2) Consistent with ActRIA expression in the extraembryonic cells, wild-type ES cells failed to rescue the gastrulation defect in chimeras in which the extraembryonic ectoderm and visceral endoderm were derived from homozygous mutant blastocysts. Furthermore, expression of HNF4, a key visceral endoderm-specific transcription regulatory factor, was significantly reduced in the mutant embryos. Together, our results indicate that ActRIA in extraembryonic cells plays a major role in early gastrulation, whereas ActRIA function is also required in embryonic tissues during later development in mice.  (+info)

Parathyroid hormone-related peptide (PTHrP)-dependent and -independent effects of transforming growth factor beta (TGF-beta) on endochondral bone formation. (8/587)

Previously, we showed that expression of a dominant-negative form of the transforming growth factor beta (TGF-beta) type II receptor in skeletal tissue resulted in increased hypertrophic differentiation in growth plate and articular chondrocytes, suggesting a role for TGF-beta in limiting terminal differentiation in vivo. Parathyroid hormone-related peptide (PTHrP) has also been demonstrated to regulate chondrocyte differentiation in vivo. Mice with targeted deletion of the PTHrP gene demonstrate increased endochondral bone formation, and misexpression of PTHrP in cartilage results in delayed bone formation due to slowed conversion of proliferative chondrocytes into hypertrophic chondrocytes. Since the development of skeletal elements requires the coordination of signals from several sources, this report tests the hypothesis that TGF-beta and PTHrP act in a common signal cascade to regulate endochondral bone formation. Mouse embryonic metatarsal bone rudiments grown in organ culture were used to demonstrate that TGF-beta inhibits several stages of endochondral bone formation, including chondrocyte proliferation, hypertrophic differentiation, and matrix mineralization. Treatment with TGF-beta1 also stimulated the expression of PTHrP mRNA. PTHrP added to cultures inhibited hypertrophic differentiation and matrix mineralization but did not affect cell proliferation. Furthermore, terminal differentiation was not inhibited by TGF-beta in metatarsal rudiments from PTHrP-null embryos; however, growth and matrix mineralization were still inhibited. The data support the model that TGF-beta acts upstream of PTHrP to regulate the rate of hypertrophic differentiation and suggest that TGF-beta has both PTHrP-dependent and PTHrP-independent effects on endochondral bone formation.  (+info)

A large number of quantitative trait loci (QTL) have been identified for growth and carcass traits on porcine chromosome one (SSC1). A key positional candidate for this chromosomal region is TGFBR1 (transforming growth factor beta type I receptor). This gene plays a key role in inherited disorders at cardiovascular, craniofacial, neurocognitive, and skeletal development in mammals. Results: In this study, 27 polymorphic SNPs in the porcine TGFBR1 gene were identified on the University of ...

Transforming growth factor beta type I receptor acts as a potent tumor suppressor in rat bladder carcinoma. : Carcinogenesis -...
Transforming growth factor beta1 (TGFbeta1) is a potent growth inhibitor for most cells, including neoplastic cells. However, there are several types of malignant cells that are resistant to its growth-inhibitory effect. LMC19, a highly malignant rat urothelial cell line, lacks TGFbeta1 receptor (TbetaRI) and is insensitive to the growth-suppresive effect of TGFbeta1. We transfected an expression vector containing human TbetaRI into this cell line. In control cells transfected with the neo gene alone, no inhibitory effect on growth was observed in vitro by the addition of anti-TGFbeta1 antibody or recombinant TGFbeta1 into serum-free medium. In contrast, the growth of all transfectants tested was inhibited significantly under serum-free conditions because of their endogenous TGFbeta synthesis. The growth was reduced further by the addition of recombinant TGFbeta1. This response pattern is consistent with TGFbeta1 mediating its effects by an autocrine and paracrine mechanism. The tumorigenicity ...

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 ...

TGF-β 3 superfamily is a group of multifunctional cytokines that affect cell growth, differentiation, apoptosis, and morphogenesis (1, 2, 3) . This family consists of ,40 family members, including TGF-βs, activins, and BMPs. TGF-β superfamily ligands induce heteromeric complex formation of cognate type II and type I serine/threonine kinase receptors. Type II receptor kinases then phosphorylate serine and threonine residues in the GS domain of type I receptors, which results in the activation of type I receptor kinases (4) . Activated type I receptors signal into cytoplasm through phosphorylation of Smad proteins. Thus far, eight mammalian Smad proteins have been identified. Smad1, Smad2, Smad3, Smad5, and Smad8 are R-Smads, which are directly phosphorylated by type I receptors. Smad2 and Smad3 are activated by the TGF-β type I receptor and the activin type IB receptor, whereas Smad1, Smad5, and Smad8 are activated by BMP type I receptors and activin receptor-like kinase 1. Smad4 is a Co-Smad ...

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 ...

Purpose: Activin receptor-like kinase 1 (ALK1) is a novel target in angiogenesis. Concurrent targeting of ALK1 and VEGF signaling results in augmented inhibition of tumor growth in renal cell carcinoma (RCC) xenograft models. Dalantercept is an ALK1-receptor fusion protein that acts as a ligand trap for bone morphogenetic proteins 9 and 10. The DART Study evaluated the safety, tolerability, pharmacokinetics, pharmacodynamics, and antitumor activity of dalantercept plus axitinib in patients with advanced RCC and determined the optimal dose for further testing.. Experimental Design: Patients received dalantercept 0.6, 0.9, or 1.2 mg/kg subcutaneously every 3 weeks plus axitinib 5 mg by mouth twice daily until disease progression or intolerance.. Results: Twenty-nine patients were enrolled in the dose escalation (n = 15) and expansion (n = 14) cohorts. There were no dose-limiting toxicities or grade 4/5 treatment-related adverse events. In addition to common VEGFR tyrosine kinase inhibitor effects, ...

This multicenter study evaluated the clinical activity and toxicity of ganetespib in molecularly defined cohorts of patients with advanced NSCLCs. Durable objective responses and disease stabilization occurred in the majority of patients with disease harboring ALK gene rearrangement who were crizotinib-naïve. In NSCLCs, ALK rearrangement results in the expression of one of several variants of the EML4-ALK fusion protein, which results in a constitutively active ALK kinase capable of activating downstream signaling cascades that promote cell proliferation and survival (5, 35, 36). In preclinical studies, ALK inhibition has been shown to induce cell death and tumor regression (17, 36, 37). The data from this trial and the recent study of IPI-504 suggest that in addition to direct tyrosine kinase inhibition, ALK can be disabled by Hsp90 inhibition, confirming preclinical predictions (17, 18). The Hsp90-inhibitory activity of ganetespib is further validation for the clinical value of this class of ...

Fibrodysplasia ossificans progressiva | Connective Tissue Gene TestsFibrodysplasia ossificans progressiva | Connective Tissue Gene Tests
Fibrodysplasia ossificans progressiva (FOP; MIM 135100) is a rare autosomal dominant disease characterized by progressive heterotopic ossification of soft connective tissues including skeletal muscle, tendons and ligaments. Individuals with FOP appear normal at birth, except for malformed great toes and thumbs. The ossification begins in early childhood and progresses over the course of a lifetime. It leads to a debilitating ankylosis of all major joints of the axial and appendicular skeleton and most patients will be confined to wheelchair by the third decade of life. Most FOP cases are sporadic, but there are reports of affected siblings. FOP is caused by mutations in the ACVR1 gene that codes for activin A receptor, type I. It belongs to the protein kinase superfamily and functions as a receptor for bone morphogenetic proteins (BMPs). BMPs are extracellular signaling proteins that are critical for the early development of heart, central nervous system, cartilage, and bone. All of the ACVR1 ...

The UCSF Medical Center and UCSF Benioff Childrens Hospital are recognized as world leaders in health care, known for innovative medicine, advanced technology and compassionate care. As an academic medical center, they are unlike community hospitals in that they offer pioneering treatments not widely available elsewhere. At their specialized Fibrodysplasia Ossificans Progressiva (FOP) Clinic, experts in both pediatric and adult orthopedics, orthopedic surgery and rheumatology are among the few in the country who readily diagnose and treat FOP. In addition, researchers at UCSF are investigating the rate of misdiagnosis of FOP and the most common causes for misdiagnosis. FOP is a rare genetic disorder that causes soft tissues to transform permanently into bone. These bones grow abnormally in the muscles, tendons, ligaments and other connective tissues, forming bridges of extra bone across the joints. As a result, movement in the areas affected by FOP is greatly restricted and sometimes impossible. ...

We further explored the physiologic significance of the ability of ACVR1[R206H] to respond to activin A in our mouse model of FOP. Inhibition of activin A with a blocking antibody completely inhibited development of HO. Although our results do not exclude the possibility that other ligands may participate, they indicate that activin A (and perhaps the activin A-containing heterodimers, activin AB and AC) must play a major, indeed obligate, role. Moreover, our data were consistent with the idea that activin A, normally produced by cells of the immune system during inflammation (22, 23), is co-opted and reinterpreted by ACVR1[R206H]-expressing cells with osteogenic potential. Hence, activin A may provide the missing link between inflammation and HO in FOP.. We would like to caution, however, that there is a paucity of data implicating activin A as the driver of HO in FOP patients per se; this is largely due to the inability to safely biopsy patients in between, or during, attacks. We cannot ...

JCI - Activin-A enhances mTOR signaling to promote aberrant chondrogenesis in fibrodysplasia ossificans progressivaJCI - Activin-A enhances mTOR signaling to promote aberrant chondrogenesis in fibrodysplasia ossificans progressiva
Fibrodysplasia ossificans progressiva (FOP) is a rare and intractable disease characterized by extraskeletal bone formation through endochondral ossification. Patients with FOP harbor point mutations in ACVR1, a type I receptor for BMPs. Although mutated ACVR1 (FOP-ACVR1) has been shown to render hyperactivity in BMP signaling, we and others have uncovered a mechanism by which FOP-ACVR1 mistransduces BMP signaling in response to Activin-A, a molecule that normally transduces TGF-β signaling. Although Activin-A evokes enhanced chondrogenesis in vitro and heterotopic ossification (HO) in vivo, the underlying mechanisms have yet to be revealed. To this end, we developed a high-throughput screening (HTS) system using FOP patient-derived induced pluripotent stem cells (FOP-iPSCs) to identify pivotal pathways in enhanced chondrogenesis that are initiated by Activin-A. In a screen of 6,809 small-molecule compounds, we identified mTOR signaling as a critical pathway for the aberrant chondrogenesis of ...

Heterotopic ossification is a pathological, non neoplastic process of bone formation at ectopic sites, especially inside mesenchymal soft tissues. The disorder can occur localized or generalized.. Local forms are mostly assigned to the entity of Myositis ossificans circumscripta and involve the skeletal muscles. As a result of trauma, often following total hip replacement, or due to neuropathic disorders, e.g. spinal cord lesions, an intramuscular osteogenesis occurs. The osteogenic stimulation of mesenchymal stem cells seems to be the cause, but the pathobiochemical pathways are not known exactly [1].. The generalized disorder Fibrodysplasia ossificans progressiva (FOP, syn. Myositis ossificans progressiva) is a rare connective tissue desease with autosomal dominant heredity. It is characterized by enchondral ossification of muscle, tendons and ligaments after simple injuries, e.g. intramuscular injection [2-4]. The influence of bone morphogenetic proteins on this disorder seems to be evident ...

MicroRNAs (miRNAs) are small noncoding RNAs that have important roles in gene regulation. We have previously reported that activin receptor-like kinase 7 (ALK7) and its ligand, Nodal, induce apoptosis in human epithelial ovarian cancer cells. In this study, we examined the regulation of ALK7 by miRNAs and demonstrate that miR-376c targets ALK7. Ectopic expression of miR-376c significantly increased cell proliferation and survival, enhanced spheroid formation and blocked Nodal-induced apoptosis. Interestingly, overexpression of miR-376c blocked cisplatin-induced cell death, whereas anti-miR-376c enhanced the effect of cisplatin. These effects of miR-376c were partially compensated by the overexpression of ALK7.

Fibrodysplasia ossificans progressiva (FOP) is a rare and intractable disease characterized by extraskeletal bone formation through endochondral ossification. Patients with FOP harbor point mutations in ACVR1, a type I receptor for BMPs. Although mutated ACVR1 (FOP-ACVR1) has been shown to render hyperactivity in BMP signaling, we and others have uncovered a mechanism by which FOP-ACVR1 mistransduces BMP signaling in response to Activin-A, a molecule that normally transduces TGF-β signaling. Although Activin-A evokes enhanced chondrogenesis in vitro and heterotopic ossification (HO) in vivo, the underlying mechanisms have yet to be revealed. To this end, we developed a high-throughput screening (HTS) system using FOP patient-derived induced pluripotent stem cells (FOP-iPSCs) to identify pivotal pathways in enhanced chondrogenesis that are initiated by Activin-A. In a screen of 6,809 small-molecule compounds, we identified mTOR signaling as a critical pathway for the aberrant chondrogenesis of ...

TGFbeta superfamily signaling is essential for the heart development :: University of Southern California Dissertations and...
Transforming growth factor betas (Tgfbetas) and Bone morphogenetic proteins (Bmps) are pleiotropic cytokines involved in many developmental processes. Organ explant studies have revealed specific roles for Tgfbeta/Bmp ligands in endothelial-mesenchymal transformations (EMT) during the formation of endocardial cushions, precursors of heart valves and septa, and in epicardial-mesenchymal transformations essential for coronary vasculature development. Gene targeting studies in mice demonstrated that the Tgfbetas/Bmps are involved in the ventricular myocardial development and formation of the neural crest-derived aorticopulmonary septum. Tgfbeta/Bmp ligands signal through a repertoire of type I and type II serine/threonine kinase receptors. In our studies, we sought to determine the requirement of Bmp type I receptor Alk2 and Tgfbeta; type I receptor Alk5 for heart development by ablating these receptors specifically in the endocardium (Tie2-Cre), in the myocardium (alphaMHC-Cre and Nkx2.5-Cre), in ...

Heterotopic ossification (HO) is a disabling condition associated with neurologic injury, inflammation, and overactive bone morphogenetic protein (BMP) signaling. The inductive factors involved in lesion formation are unknown. We found that the expression of the neuro-inflammatory factor Substance P (SP) is dramatically increased in early lesional tissue in patients who have either fibrodysplasia ossificans progressiva (FOP) or acquired HO, and in three independent mouse models of HO. In Nse-BMP4, a mouse model of HO, robust HO forms in response to tissue injury; however, null mutations of the preprotachykinin (PPT) gene encoding SP prevent HO. Importantly, ablation of SP+ sensory neurons, treatment with an antagonist of SP receptor NK1r, deletion of NK1r gene, or genetic down-regulation of NK1r-expressing mast cells also profoundly inhibit injury-induced HO. These observations establish a potent neuro-inflammatory induction and amplification circuit for BMP-dependent HO lesion formation, and ...

PHILADELPHIA - An international team of scientists, led by researchers at the University of Pennsylvania School of Medicine, is taking the first step in developing a treatment for a rare genetic disorder called fibrodysplasia ossificans progressiva (FOP), in which the bodys skeletal muscles and soft connective tissue turns to bone, immobilizing patients over a lifetime with a second skeleton.. Reporting in the November issue of the Journal of Clinical Investigation senior authors Eileen Shore, PhD, Professor of Genetics and Orthopedics, and Mary Mullins, PhD, Professor of Cell and Developmental Biology, with scientists in Japan and Germany, demonstrated that the mutation that causes FOP mistakenly activates a cascade of biochemical events in soft tissues that kicks off the process of bone development. The linchpin of the cellular signaling gone awry is a receptor for a bone morphogenetic protein, or BMP.. The present study provides the first clear glimpse of how FOP might develop at a cellular ...

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 ...

Cell culture. iPSCs were maintained in primate embryonic stem (ES) cell medium (ReproCELL) supplemented with 4 ng/ml recombinant human FGF2 (Wako Pure Chemical). To activate the production of induced neural crest cells (iNCCs), mTeSR1 medium (STEMCELL Technologies) was used for the feeder-free culturing of iPSCs. The induction and maintenance of iNCCs and iMSCs derived from iPSCs were previously described (43, 45) (Supplemental Figure 1A). Briefly, iNCCs were induced in chemically defined medium (CDM) supplemented with 10 μM SB-431542 and 1 μM CHIR99021 for 7 days. iNCCs were maintained in CDM supplemented with 10 μM SB-431542, 20 ng/ml FGF2, and 20 ng/ml recombinant human EGF (R&D Systems), and we used up to 20 passages in this study. iMSCs were induced and maintained in αMEM (Invitrogen, Thermo Fisher Scientific) supplemented with 10% (v/v) FBS (Nichirei), 5 ng/ml FGF2, and 0.5% penicillin and streptomycin (Invitrogen, Thermo Fisher Scientific).

Mutations in tumors can create a state of increased cellular plasticity that promotes resistance to treatment. Thus, there is an urgent need to develop novel strategies for identifying key factors that regulate cellular plasticity in order to combat resistance to chemotherapy and radiation treatment. Here we report that prostate epithelial cell reprogramming could be exploited to identify key factors required for promoting prostate cancer tumorigenesis and cellular plasticity. Deletion of phosphatase and tensin homolog (Pten) and transforming growth factor-beta receptor type 2 (Tgfbr2) may increase prostate epithelial cell reprogramming efficiency in vitro and cause rapid tumor development and early mortality in vivo ...

The transforming growth factor‐β (TGF‐β) superfamily constitutes a large family of secreted signaling molecules which are known to have important roles in regulating a wide variety of cellular processes including proliferation, differentiation, adhesion and migration (Roberts and Sporn, 1990; Kingsley, 1994). All known receptors of this superfamily signal through a heteromeric complex of type I and type II transmembrane receptor serine/threonine kinases which act in series (Derynck and Feng, 1997; Massague, 1998). Despite extensive knowledge about the receptor activation mechanisms, which involve recruitment and activation of the type I receptor kinase by the ligand‐activated type II receptor kinase, the downstream signaling pathways from the activated type I receptor are not yet clearly defined. Recently, a set of novel mammalian proteins, termed SMADs, has been identified based on their high homology to the Drosophila Mad and the Caenorhabditis elegans Sma proteins, which were ...

In the present study, we provided the first characterization of the ACVR1 gene promoter region. This gene is mutated in patients affected by FOP, causing a hyper-activation of the BMP SMAD-dependent signaling pathway. The pathogenic events resulting in heterotopic ossification in FOP are associated with mechanisms related to inflammatory stimuli that trigger osteogenic differentiation in pluripotent progenitors in postnatal life. It is conceivable that these mechanisms could be targeted to some levels of BMP signaling pathways thus providing strategies to control the most devastating effects of this genetically-based disorder in extra-skeletal tissues.. The discovery of ACVR1 as the gene responsible for FOP has opened the way to treatment discovery efforts, considering that the identification of a molecular target related to the disease is the very first step of a drug development process. Elements and factors controlling regulation of gene and protein expression can be considered as sensitive ...

Cripto - WikipediaCripto - Wikipedia
Cripto is an EGF-CFC or epidermal growth factor-CFC, which is encoded by the Cryptic family 1 gene. Cryptic family protein 1B is a protein that in humans is encoded by the CFC1B gene. Cryptic family protein 1B acts as a receptor for the TGF beta signaling pathway. It has been associated with the translation of an extracellular protein for this pathway. The extracellular protein which Cripto encodes plays a crucial role in the development of left and right division of symmetry. Mutations of it could cause congenital heart disease. Crypto is a glycosylphosphatidylinositol-anchored co-receptor that binds nodal and the activin type I ActRIB (ALK)-4 receptor (ALK4). Cripto is composed of two adjacent cysteine-rich motifs: the EGF-like and the CFC of an N-terminal signal peptide and of a C-terminal hydrophobic region attached by a GPI anchor, which makes it a potentially essential element in the signaling pathway directing vertebrate embryo development. NMR data confirm that the CFC domain has a ...
