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.

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.

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.

The homeobox gene Pitx2: mediator of asymmetric left-right signaling in vertebrate heart and gut looping. (1/13538)

Left-right asymmetry in vertebrates is controlled by activities emanating from the left lateral plate. How these signals get transmitted to the forming organs is not known. A candidate mediator in mouse, frog and zebrafish embryos is the homeobox gene Pitx2. It is asymmetrically expressed in the left lateral plate mesoderm, tubular heart and early gut tube. Localized Pitx2 expression continues when these organs undergo asymmetric looping morphogenesis. Ectopic expression of Xnr1 in the right lateral plate induces Pitx2 transcription in Xenopus. Misexpression of Pitx2 affects situs and morphology of organs. These experiments suggest a role for Pitx2 in promoting looping of the linear heart and gut.  (+info)

A Drosophila doublesex-related gene, terra, is involved in somitogenesis in vertebrates. (2/13538)

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

Requirement of a novel gene, Xin, in cardiac morphogenesis. (3/13538)

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

Regulation of body length and male tail ray pattern formation of Caenorhabditis elegans by a member of TGF-beta family. (4/13538)

We have identified a new member of the TGF-beta superfamily, CET-1, from Caenorhabditis elegans, which is expressed in the ventral nerve cord and other neurons. cet-1 null mutants have shortened bodies and male tail abnormal phenotype resembling sma mutants, suggesting cet-1, sma-2, sma-3 and sma-4 share a common pathway. Overexpression experiments demonstrated that cet-1 function requires wild-type sma genes. Interestingly, CET-1 appears to affect body length in a dose-dependent manner. Heterozygotes for cet-1 displayed body lengths ranging between null mutant and wild type, and overexpression of CET-1 in wild-type worms elongated body length close to lon mutants. In male sensory ray patterning, lack of cet-1 function results in ray fusions. Epistasis analysis revealed that mab-21 lies downstream and is negatively regulated by the cet-1/sma pathway in the male tail. Our results show that cet-1 controls diverse biological processes during C. elegans development probably through different target genes.  (+info)

Smad3-Smad4 and AP-1 complexes synergize in transcriptional activation of the c-Jun promoter by transforming growth factor beta. (5/13538)

Transcriptional regulation by transforming growth factor beta (TGF-beta) is a complex process which is likely to involve cross talk between different DNA responsive elements and transcription factors to achieve maximal promoter activation and specificity. Here, we describe a concurrent requirement for two discrete responsive elements in the regulation of the c-Jun promoter, one a binding site for a Smad3-Smad4 complex and the other an AP-1 binding site. The two elements are located 120 bp apart in the proximal c-Jun promoter, and each was able to independently bind its corresponding transcription factor complex. The effects of independently mutating each of these elements were nonadditive; disruption of either sequence resulted in complete or severe reductions in TGF-beta responsiveness. This simultaneous requirement for two distinct and independent DNA binding elements suggests that Smad and AP-1 complexes function synergistically to mediate TGF-beta-induced transcriptional activation of the c-Jun promoter.  (+info)

p38 mitogen-activated protein kinase can be involved in transforming growth factor beta superfamily signal transduction in Drosophila wing morphogenesis. (6/13538)

p38 mitogen-activated protein kinase (p38) has been extensively studied as a stress-responsive kinase, but its role in development remains unknown. The fruit fly, Drosophila melanogaster, has two p38 genes, D-p38a and D-p38b. To elucidate the developmental function of the Drosophila p38's, we used various genetic and pharmacological manipulations to interfere with their functions: expression of a dominant-negative form of D-p38b, expression of antisense D-p38b RNA, reduction of the D-p38 gene dosage, and treatment with the p38 inhibitor SB203580. Expression of a dominant-negative D-p38b in the wing imaginal disc caused a decapentaplegic (dpp)-like phenotype and enhanced the phenotype of a dpp mutant. Dpp is a secretory ligand belonging to the transforming growth factor beta superfamily which triggers various morphogenetic processes through interaction with the receptor Thick veins (Tkv). Inhibition of D-p38b function also caused the suppression of the wing phenotype induced by constitutively active Tkv (TkvCA). Mosaic analysis revealed that D-p38b regulates the Tkv-dependent transcription of the optomotor-blind (omb) gene in non-Dpp-producing cells, indicating that the site of D-p38b action is downstream of Tkv. Furthermore, forced expression of TkvCA induced an increase in the phosphorylated active form(s) of D-p38(s). These results demonstrate that p38, in addition to its role as a transducer of emergency stress signaling, may function to modulate Dpp signaling.  (+info)

Isolation of zebrafish gdf7 and comparative genetic mapping of genes belonging to the growth/differentiation factor 5, 6, 7 subgroup of the TGF-beta superfamily. (7/13538)

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

Transformation of intestinal epithelial cells by chronic TGF-beta1 treatment results in downregulation of the type II TGF-beta receptor and induction of cyclooxygenase-2. (8/13538)

The precise role of TGF-beta in colorectal carcinogenesis is not clear. The purpose of this study was to determine the phenotypic alterations caused by chronic exposure to TGF-beta in non-transformed intestinal epithelial (RIE-1) cells. Growth of RIE-1 cells was inhibited by >75% following TGF-beta1 treatment for 7 days, after which the cells resumed a normal growth despite the presence of TGF-beta1. These 'TGF-beta-resistant' cells (RIE-Tr) were continuously exposed to TGF-beta for >50 days. Unlike the parental RIE cells, RIE-Tr cells lost contact inhibition, formed foci in culture, grew in soft agarose. RIE-Tr cells demonstrated TGF-beta-dependent invasive potential in an in vitro assay and were resistant to Matrigel and Na-butyrate-induced apoptosis. The RIE-Tr cells were also tumorigenic in nude mice. The transformed phenotype of RIE-Tr cells was associated with a 95% decrease in the level of the type II TGF-beta receptor (TbetaRII) protein, a 40-fold increase in cyclooxygenase-2 (COX-2) protein, and 5.9-fold increase in the production of prostacyclin. Most RIE-Tr subclones that expressed low levels of TbetaRII and high levels of COX-2 were tumorigenic. Those subclones that express abundant TbetaRII and low levels of COX-2 were not tumorigenic in nude mice. A selective COX-2 inhibitor inhibited RIE-Tr cell growth in culture and tumor growth in nude mice. The reduced expression of TbetaRII, increased expression of COX-2, and the ability to form colonies in Matrigel were all reversible upon withdrawal of exogenous TGF-beta1 for the RIE-Tr cells.  (+info)

Transforming Growth Factor beta3: A TGF-beta subtype that plays role in regulating epithelial-mesenchymal interaction during embryonic development. It is synthesized as a precursor molecule that is cleaved to form mature TGF-beta3 and TGF-beta3 latency-associated peptide. The association of the cleavage products results in the formation a latent protein which must be activated to bind its receptor.
Transforming growth factor-beta (TGF-beta) is a secreted polypeptide that signals via receptor serine/threonine kinases and intracellular Smad effectors. TGF-beta inhibits proliferation and induces apoptosis in various cell types, and accumulation of loss-of-function mutations in the TGF-beta receptor or Smad genes classify the pathway as a tumor suppressor in humans. In addition, various oncogenic pathways directly inactivate the TGF-beta receptor-Smad pathway, thus favoring tumor growth. On the other hand, all human tumors overproduce TGF-beta whose autocrine and paracrine actions promote tumor cell invasiveness and metastasis. Accordingly, TGF-beta induces epithelial-mesenchymal transition, a differentiation switch that is required for transitory invasiveness of carcinoma cells. Tumor-derived TGF-beta acting on stromal fibroblasts remodels the tumor matrix and induces expression of mitogenic signals towards the carcinoma cells, and upon acting on endothelial cells and pericytes, TGF-beta ...
Experimental evidence suggests that transforming growth factor (TGF) beta1 is a fibrogenic cytokine. The histopathological changes of chronic renal allograft nephropathy are dominated by fibrotic changes and TGF-beta may have an important aetiological role.

|p|Noggin inhibits TGF-beta signal transduction by binding to TGF-beta family ligands and preventing them from binding to their corresponding receptors. Noggin plays a key role in neural induction by inhibiting BMP4, along with other TGF-beta signaling inhibitors such as chordin and follistatin. Mouse knockout experiments have demonstrated that noggin also plays a crucial role in bone development, joint formation, and neural tube fusion. |br/|The secreted polypeptide noggin, encoded by the NOG gene, binds and inactivates members of the transforming TGF-beta superfamily signaling proteins, such as BMP4. By diffusing through extracellular matrices more efficiently than members of the TGF-beta superfamily, noggin may have a principal role in creating morphogenic gradients.|/p|
Endothelial cells plated on two-dimensional (2-D) substrata proliferate until they form a tightly apposed confluent monolayer of quiescent cells that display a typical cobblestone morphology. When added to proliferating cultures TGF beta-1 (transforming growth factor beta-1) inhibited cell growth and caused marked morphological changes, with the cells becoming enlarged and ragged. These effects were dose-dependent and reversible. TGF beta-1 also reduced the cloning efficiency and colony size of these cells, indicating that TGF beta-1 is cytotoxic and cytostatic for endothelial cells. By contrast, TGF beta-1 added to quiescent cobblestone cultures did not affect cell morphology or cell numbers. In the presence of 20% serum, the level of total protein synthesis per cell was significantly increased by TGF beta-1 in a dose-dependent manner when the cells were cultured on a 2-D substratum, regardless of whether the cells were proliferating or cobblestone quiescent. The level of plasminogen ...
Isoform-specific antibodies to TGF beta 1, TGF beta 2, and TGF beta 3 proteins were generated and have been used to examine the expression of these factors in the developing mouse embryo from 12.5-18.5 d post coitum (d.p.c.). These studies demonstrate the initial characterization of both TGF beta 2 and beta 3 in mammalian embryogenesis and are compared with TGF beta 1. Expression of one or all three TGF beta proteins was observed in many tissues, e.g., cartilage, bone, teeth, muscle, heart, blood vessels, lung, kidney, gut, liver, eye, ear, skin, and nervous tissue. Furthermore, all three TGF beta proteins demonstrated discrete cell-specific patterns of expression at various stages of development and the wide variety of tissues expressing TGF beta proteins represent all three primary embryonic germ layers. For example, specific localization of TGF beta 1 was observed in the lens fibers of the eye (ectoderm), TGF beta 2 in the cortex of the adrenal gland (mesoderm), and TGF beta 3 in the cochlear ...
The transforming growth factor-beta (TGF-beta) family comprising a large group of extracellular growth factors controls the development of the organism. TGF-beta family members consists of a large number of structurally related polypeptide growth factors, each capable of regulating a fascinating array of cellular processes including cell proliferation, differentiation, motility, adhesion, and death. TGF-beta and related factors play a prominent role in the development, homeostasis and repair of virtually all tissues in organisms. ...
The 1D11.16.8 monoclonal antibody reacts with mouse, human, rat, monkey, hamster, canine and bovine TGF-β (transforming growth factor beta) isoforms 1, 2 and 3. TGF-β is a multifunctional cytokine that regulates the proliferation of epithelial cells, endothelial cells, fibroblasts, neurons, lymphoid cells including T lymphocytes and NK cells, and other hematopoietic cell types. TGF-β also regulates the activities of activated macrophages and the development of regulatory T cells. Additionally, TGF-β plays roles in immune function, tissue remodeling and wound repair. TGF-β exists as five highly similar isoforms (TGF-β 1-5) with homologies of 70-80%. TGF-β1 is synthesized by the enzymatic cleavage of a long precursor TGF-β1 polypeptide encoded by the |em|TGFB1|/em| gene which yields the mature protein and the Latency Associated Peptide (LAP). The LAP and mature TGF-β1 non-covalently associate during secretion. TGF-β is ubiquitously expressed by many cell types including macrophages and platelets

In the present study, concentrations of TGF-β1 in plasma were decreased in 87% of patients with Guillain-Barré syndrome on admission, increased with motor function up to control concentrations during the next 15 days at the time of early recovery, and correlated well with the disability score. TNF-α concentrations were raised in 60% of patients on admission, and did not significantly decrease from day 1 to day 15 of the hospital stay. Other cytokines were either randomly increased (IL-2, IL-6), or undetectable in the circulation (IL-1, IL-4, IL-7, IL-10).. Treatments could not account for the down regulation of TGF-β1 seen on admission of patients. During treatment, both patients undergoing PE and patients receiving IVIg had decreased plasma concentrations of TGF-β1. PE was associated with lower concentrations of TGF-β1 in plasma than IVIg at day 7. This could have resulted from some removal of TGF-β1 (PE), or addition of TGF-β1 (IVIg) at the time of treatment..

TGF-β and its related factors regulate a broad range of cellular functions, including proliferation, differentiation, apoptosis, migration, and adhesion. These factors are also very important in the pathogenesis of cancer and many other diseases. Although much has been known about the TGF-β signaling pathway since the discovery of Smads 15 years ago, remarkable progress has been made in revealing details of different regulatory mechanisms that afford a full range of control of the biological functions of these factors in the TGF-β family. Specific physiological and pathological roles of TGF-β/Smad in different cellular context also start to emerge. This collection of review articles provides a broad, albeit not all-inclusive, overview of the latest breakthroughs and developments in TGF-β signaling and biology. Dr Ying Zhang. ...

Zwijsen A., Goumans M.J., Lawson K.A., Van Rooijen M.A., Mummery C.L.. Transforming growth factor beta (TGFbeta) regulates the cell cycle and extracellular matrix (ECM) deposition of many cells in vitro. We have analysed chimaeric mouse embryos generated from embryonic stem cells with abnormal receptor expression to study the effect of TGFbeta on these processes in vivo and the consequences for normal development. The binding receptor for TGFbeta, TbetaRII, is first detected in the embryo proper around day 8.5 in the heart. Ectopic expression of TbetaRII from the blastocyst stage onward resulted in an embryonic lethal around 9.5 dpc. Analysis of earlier stages revealed that the primitive streak of TbetaRII chimaeras failed to elongate. Furthermore, although cells passed through the streak and initially formed mesoderm, they tended to accumulate within the streak. These defects temporally and spatially paralleled the expression of the TGFbeta type I receptor, which is first expressed in the node ...

The role of transforming growth factors type beta (TGF-beta) was investigated during murine embryogenesis. There are three known mammalian TGF-beta genes. The developmental pattern of expression of TGF-beta RNA has previously been elucidated by in situ hybridisation and the localisation of TGF-beta1 protein by immunohistochemistry. Based on this data it has been suggested that TGF-beta1 acts in both a paracrine and autocrine role during development. The expression of both TGF-beta2 and TGF-beta3 RNA has been observed in murine embryos by Northern analysis. In order to understand the role of these two genes, individually, and in relation with each other, the developmental regulation of all three genes was investigated by in situ hybridisation using mouse specific probes on serial mouse embryo sections from 6.5 days p.c. to 16.5 days p.c.. A comparison was made of the data concerning the temporal and spatial expression patterns of TGF-beta1, TGF-beta2 and TGF-beta3 RNA, and the role of each gene ...
Transforming growth factor-beta receptor III (TGF-beta RIII) is one of three receptors for the secreted growth factor TGF-beta. Unlike type I and type II TGF-beta receptors, TGF-beta RIII does not participate directly in the propagation of intracellular signaling in response to TGF-beta binding.
To better define the role of Ids in melanomagenesis, we hypothesized expressing Id2, Id3 or Id4 along with Smad7 would revert 1205Lu/S7 cells back to the tumorigenic state. Subcutaneous injection of TGF-β-dependent 1205Lu cells co-expressing Id2, Id3, or Id4, with Smad7 bypassed the tumorigenic block mediated by Smad7, generating TGF-β-independent tumors and re-upregulated metastasis-related genes. Surprisingly, 1205Lu/S7 cells expressing Id4, but not Id2 or Id3, activated robust melanin production in amelanotic 1205Lu cells, confirmed by Fontana-Masson stain, de-novo expression of MART-1 and tyrosinase proteins. Mechanistic investigation revealed M-MITF phosphorylation and MART-1 promoter activation in 1205Lu and WM852 melanoma cells, suggesting broader implications for Id4 in melanoma. In human tumors melanin corresponded with Id4 localization. Additionally, pigment-laden CD163+ mouse histiocytes, with areas of extensive necrosis were found throughout S7/Id4 tumors only. Current ...
Members of the transforming growth factor beta (TGF beta) family initiate cellular responses by binding to TGF beta receptor type II (Tf3R11) and type I (TpRI) serine/threonine kinases, whereby Srnad2 and Smad3 are phosphorylated and activated, promoting their association with Smadzi. We report here that T beta RI interacts with the SH3 domains of the adaptor protein CIN85 in response to TGF beta stimulation in a TRAF6-dependent manner. Small interfering RNA mediated knockdown of CIN85 resulted in accumulation of T beta RI in intracellular compartments and diminished TGF beta-stimulated Sniad2 phosphorylation. Overexpression of CIN85 instead increased the amount of T beta RI at the cell surface. This effect was inhibited by a dominant-negative mutant of Rab11, suggesting that CIN85 promoted recycling of TGF beta receptors. CIN85 enhanced TGF beta-stimulated Smad2 phosphorylation, transcriptional responses, and cell migration. CIN85 expression correlated with the degree of malignancy of prostate ...
Clone CH6-17E5.1 reacts with the N-terminal latency-associated peptide (LAP) of the transforming growth factor β1 (TGF-β1) dimer. TGF-β1 belongs to a family of homologous, disulfide-linked, homodimeric proteins. These highly pleiotropic cytokines inhibit proliferation of most cells, but can promote the growth of mesenchymal cells and enhance extracellular matrix formation. The pivotal function of TGF-β1 in the immune system is to mediate immunosuppression and maintain tolerance by regulating lymphocyte proliferation, differentiation, and survival. TGF-β1 is produced by many cell types, but is reported to be most abundant in mammalian platelets and bone. It is secreted predominantly as an inactive latent complex. After proteolytical processing of the TGF-β1 precursor, the resulting N-terminal latency-associated peptide (LAP) remains non-covalently associated with the TGF-β1 dimer. Mature and biologically active TGF-β1 can be released from the complex by action of proteases and/or conformational
The secreted polypeptide transforming growth factor-beta (TGF-beta) exerts its multiple activities through type I and II cell surface receptors. In epithelial cells, activation of the TGF-beta signal transduction pathways leads to inhibition of cell proliferation and an increase in extracellular matrix production. TGF-beta is widely expressed during development and its biological activity has been implicated in epithelial-mesenchymal interactions, e.g., in branching morphogenesis of the lung, kidney, and mammary gland, and in inductive events between mammary epithelium and stroma. In the present study, we investigated the effects of TGF-beta on mouse mammary epithelial cells in vitro. TGF-beta reversibly induced an alteration in the differentiation of normal mammary epithelial NMuMG cells from epithelial to fibroblastic phenotype. The change in cell morphology correlated with (a) decreased expression of the epithelial markers E-cadherin, ZO-1, and desmoplakin I and II; (b) increased expression ...

Previous studies have indicated that the cytokine transforming growth factor beta 1 (TGF beta 1) has immunosuppressive properties and can inhibit the production of tumor necrosis factor (TNF) and Interleukin 1 (IL 1) by human peripheral blood mononuclear cells. In this study, we have examined the effects of TGF beta 1 on the production of Interleukin 6 (IL 6) by human peripheral blood mononuclear cells. Treatment with only TGF beta 1 leads to the induction of IL 6, and this was both dose- and time-dependent. The effect of TGF beta 1 was evident at the level of IL 6 mRNA, suggesting TGF beta 1-induced de novo synthesis of IL 6. Induction of IL 6 by TGF beta 1 was specific, as other cytokines made by mononuclear cells (TNF and IL 1) were not induced by TGF beta 1. Furthermore, when a panel of stimuli were compared for their ability to induce IL 1, TNF and IL 6 in the presence or absence of TGF beta 1, IL 6 levels were augmented in the presence of TGF beta 1, while the induction of IL 1 and TNF was
Transforming growth factor beta (TGF-β) is a multifunctional cytokine belonging to the transforming growth factor superfamily that includes four different isoforms (TGF-β 1 to 4, HGNC symbols TGFB1, TGFB2, TGFB3, TGFB4) and many other signaling proteins produced by all white blood cell lineages. Activated TGF-β complexes with other factors to form a serine/threonine kinase complex that binds to TGF-β receptors, which is composed of both type 1 and type 2 receptor subunits. After the binding of TGF-β, the type 2 receptor kinase phosphorylates and activates the type 1 receptor kinase that activates a signaling cascade. This leads to the activation of different downstream substrates and regulatory proteins, inducing transcription of different target genes that function in differentiation, chemotaxis, proliferation, and activation of many immune cells. TGF-β is secreted by many cell types, including macrophages, in a latent form in which it is complexed with two other polypeptides, latent ...
Serine protease with a variety of targets, including extracellular matrix proteins such as fibronectin. HTRA1-generated fibronectin fragments further induce synovial cells to up-regulate MMP1 and MMP3 production. May also degrade proteoglycans, such as aggrecan, decorin and fibromodulin. Through cleavage of proteoglycans, may release soluble FGF-glycosaminoglycan complexes that promote the range and intensity of FGF signals in the extracellular space. Regulates the availability of insulin-like growth factors (IGFs) by cleaving IGF-binding proteins. Inhibits signaling mediated by TGF-beta family members. This activity requires the integrity of the catalytic site, although it is unclear whether TGF-beta proteins are themselves degraded. By acting on TGF-beta signaling, may regulate many physiological processes, including retinal angiogenesis and neuronal survival and maturation during development. Intracellularly, degrades TSC2, leading to the activation of TSC2 downstream targets ...

A series of site-specific insertion and deletion mutants was prepared in the pro domain of transforming growth factor beta 1 (TGF beta 1) encoded by simian TGF beta 1 cDNA. These mutants were transiently expressed in COS-1 cells and the ability of each to be properly processed, folded correctly, and secreted was determined by immunoblot analysis of cells and culture supernatants. Insertions in regions corresponding to amino acid residues 50, 154, and 170 blocked secretion; culture supernatants from COS-1 cells showed no immunologically reactive proteins, whereas intact cells contained high levels of the mutant polypeptides. Insertions in the middle portion of the pro domain at residues 81, 85, and 144 affected disulfide maturation of the mature TGF beta 1. An insertion at residue 110, on the other hand, appeared to destabilize the mature TGF beta 1 polypeptide, resulting in degraded growth factor. Relatively small (10 amino acids) to large (125 amino acids) deletion mutations in the pro domain ...
TGF-beta is a secreted cytokine, which plays an important role in cell development, differentiation, and homeostasis in both physiologic and pathologic conditions, such as tumorigenesis, abnormal wound healing and skin cancer. TGF-beta transmit signal from the extracellular environment to intracellular signaling networks via its cell surface receptor complex, the TGF-beta type II/ I receptor (TbetaRII/TbetaRI) heterodimer. TGF-beta ligand binds to TbetaRII, which in turn recruits and activates TbetaRI, resulting in activation of downstream signaling complex, receptor Smads (R-Smads) and common Smad4. TGF-beta stimulation is also known to activate R-Smad-independent signaling pathways, such as the extracellular signal-regulated kinase (ERK1/2) pathway. However, two long-standing questions remained: 1) why TGF-beta activates ERK depends on the cell context and 2) whether or not TbetaRII is able to mediate the TGF-beta signaling without the participation of TbetaRI. In the chapter two, it is shown ...
Transforming growth factor beta 1 or TGF-β1 is a polypeptide member of the transforming growth factor beta superfamily of cytokines. It is a secreted protein that performs many cellular functions, including the control of cell growth, cell proliferation, cell differentiation and apoptosis. In humans, TGF-β1 is encoded by the TGFB1 gene. TGF-β is a multifunctional set of peptides that controls proliferation, differentiation, and other functions in many cell types. TGF-β acts synergistically with TGFA in inducing transformation. It also acts as a negative autocrine growth factor. Dysregulation of TGF-β activation and signaling may result in apoptosis. Many cells synthesize TGF-β and almost all of them have specific receptors for this peptide. TGF-β1, TGF-β2, and TGF-β3 all function through the same receptor signaling systems. TGF-β1 was first identified in human platelets as a protein with a molecular mass of 25 kilodaltons with a potential role in wound healing. It was later ...
Cytokines of the transforming growth factor beta (TGF-beta) superfamily, including TGF-betas, activins and bone morphogenetic proteins (BMPs), bind to specific serine/threonine kinase receptors and transmit intracellular signals through Smad proteins. Upon ligand stimulation, Smads move into the nucleus and function as components of transcription complexes. TGF-beta and BMP signaling is regulated positively and negatively through various mechanisms. Positive regulation amplifies signals to a level sufficient for biological activity. Negative regulation occurs at the extracellular, membrane, cytoplasmic and nuclear levels. TGF-beta and BMP signaling is often regulated through negative feedback mechanisms, which limit the magnitude of signals and terminate signaling. Negative regulation is also important for formation of gradients of morphogens, which is crucial in developmental processes. In addition, other signaling pathways regulate TGF-beta and BMP signaling through cross-talk. Nearly 20 BMP ...
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 ...
TY - JOUR. T1 - Transforming growth factor-beta protection of cancer cells against tumor necrosis factor cytotoxicity is counteracted by hyaluronidase (review).. AU - Chang, N. S.. PY - 1998/12. Y1 - 1998/12. N2 - Numerous cancer cells, when exposed to transforming growth factor beta (TGF-beta), become resistant to tumor necrosis factor (TNF) cytotoxicity. Pretreatment of L929 fibroblasts, for example, with TGF-beta isoforms (beta 1, beta 2 and beta 3) for at least 0.5-1 h results in resistance to TNF killing. TGF-beta 1 mediates the following sequential events in L929 cells: i) rapid induction of protein tyrosine-phosphorylation (, 30 min), ii) stimulation of protective protein synthesis and acquisition of TNF resistance (approximately 0.5-1 h), and iii) suppression of I kappa B-alpha expression (1-2 h). Two protective proteins induced by TGF-beta 1 are a 46 kDa extracellular matrix TNF-resistance triggering (TRT) protein and a putative transmembrane anti-apoptotic adhesion protein TIF2 ...
DESCRIPTION (provided by applicant): Tumor cells that are resistant to the growth inhibitory effects of TGF? can still secrete TGF?, which enhances tumorigenesis via the paracrine effects of TGF? in the tumor microenvironment. It is advantageous to block this secreted TGF? in late-stage tumors that have lost the TGF? growth inhibitory signals. We have identified the signaling pathways mediating TGF?1 production in untransformed epithelial cells (UECs) and in human colon cancer cells (HCCCs). One of the differences involves a switching of the AP-1 transcription factors (TFs) bound to the relevant region of the TGF?1 promoter. Here we will explore the mechanisms underlying this TF switching, including the role played by altered compartmentalization of signaling complexes. In addition, we have identified the novel TGF? signaling intermediate km23, which is also a light chain of the motor protein dynein (DLC). The dynein motor complex can transport membrane vesicles (ie, endosomal compartments) ...
Transforming growth factor beta (TGF-beta) has a strong impact on liver development and physiopathology, exercised through its pleiotropic effects on growth, differentiation, survival, and migration. When exposed to TGF-beta, the mhAT3F cells, immortalized, highly differentiated hepatocytes, maintained their epithelial morphology and underwent dramatic alterations of adhesion, leading to partial or complete detachment from a culture plate, followed by readhesion and spreading. These alterations of adhesive behavior were caused by sequential changes in expression of the alpha5beta1 integrin and of its ligand, the fibronectin. The altered specificity of anchorage to the extracellular matrix gave rise to changes in cells collective motility: cohorts adhering to fibronectin maintained a persistent, directional motility, with ezrin-rich pathfinder cells protruding from the tips of the cohorts. The absence of adhesion to fibronectin prevented the appearance of polarized pathfinders and lead to ...

Scientists have long known that a small protein Dr. Saikumar was studying, Transforming Growth Factor-Beta (TGF-B), behaves in a paradoxical way. When a cell begins undergoing the transformation into a cancerous state, TGF-B can stop that growth and protects us from developing cancer. But if that cell escapes the TGF-B surveillance, then it will advance into a full-blown cancer cell and TGF-B can help it thrive and spread faster.. Turning off this treasonous action of TGF-B alone may indeed be advantageous, the pathologist said.. Although TGF-B has received intense scrutiny in the 30 years since its discovery, little is understood as to just how it turns from a tumor suppressor into a tumor promoter. Researchers found that if they suppress TGF-B activity to starve a cancerous tumor, a new tumor is likely to start growing, since the proteins helpful function in preventing new cancerous development is also switched off.. But Dr. Saikumar found a clue in an obscure protein called TMEPAI, and ...
