Platelets release CXCL4L1, a nonallelic variant of the chemokine platelet factor-4/CXCL4 and potent inhibitor of angiogenesis. (1/25)

Platelet factor-4 (PF-4)/CXCL4 was the first chemokine described to inhibit neovascularization. Here, the product of the nonallelic variant gene of CXCL4, PF-4var1/PF-4alt, designated CXCL4L1, was isolated for the first time from thrombin-stimulated human platelets and purified to homogeneity. Although secreted CXCL4 and CXCL4L1 differ in only three amino acids, CXCL4L1 was more potent in inhibiting chemotaxis of human microvascular endothelial cells toward interleukin-8 (IL-8)/CXCL8 or basic fibroblast growth factor (bFGF). In vivo, CXCL4L1 was also more effective than CXCL4 in inhibiting bFGF-induced angiogenesis in rat corneas. Thus, activated platelets release CXCL4L1, a potent regulator of endothelial cell biology, which affects angiogenesis and vascular diseases.  (+info)

BMP-1/Tolloid-like metalloproteases process endorepellin, the angiostatic C-terminal fragment of perlecan. (2/25)

Endorepellin, the C-terminal domain of the heparan sulfate proteoglycan perlecan, possesses angiostatic activity. The terminal laminin-like globular (LG3) domain of endorepellin appears to possess most of the biological activity on endothelial cells. LG3 protein has been detected in the urine of patients with end-stage renal disease and in the amniotic fluid of pregnant women with premature rupture of fetal membranes. These findings suggest that proteolytic processing of endorepellin and the generation of LG3 might have biological significance. In this study, we have identified specific enzymes of the bone morphogenetic protein-1 (BMP-1)/Tolloid family of metalloproteases that cleave LG3 from recombinant endorepellin at the physiologically relevant site and that cleave LG3 from endogenous perlecan in cultured mouse and human cells. The BMP-1/Tolloid family of metalloproteases is thereby implicated in the processing of a major basement membrane proteoglycan and in the liberation of an anti-angiogenic factor. Using molecular modeling, site-directed mutagenesis and angiogenic assays, we further demonstrate that LG3 activity requires specific amino acids involved in Ca(2+) coordination.  (+info)

Angiostatic peptides use plasma fibronectin to home to angiogenic vasculature. (3/25)

A group of angiogenesis inhibitors are derived from fragments of extracellular matrix or blood proteins. Endostatin, antithrombin, and anastellin are members of this group of substances. The plasma adhesion proteins fibronectin and vitronectin serve as cofactors for these three antiangiogenic proteins. Anginex is a synthetic 33-amino acid peptide that was originally modeled to reproduce the beta-sheet structure of antiangiogenic proteins. Here, we show that anginex initiates fibronectin polymerization and is inactive in mice that lack plasma fibronectin. Anginex shares these characteristics with anastellin. Fluorescein-labeled anginex and anastellin specifically localized in angiogenic vessels in vivo. This localization was dependent on plasma fibronectin and inhibited by an Arg-Gly-Asp peptide. Thus, anginex shares with several physiological angiogenesis inhibitors a dependence on plasma adhesion proteins. The role of the adhesion protein interaction apparently is to form integrin-binding complexes that deliver the antiangiogenic proteins to sites of angiogenesis. This functional convergence of several antiangiogenic factors has important implications for antiangiogenic therapies.  (+info)

Identification of CD36 molecular features required for its in vitro angiostatic activity. (4/25)

Thrombospondin-1 (TSP-1), a natural inhibitor of angiogenesis, acts directly on endothelial cells (EC) via CD36 to inhibit their migration and morphogenesis induced by basic fibroblast growth factor. Here we show that CD36 triggered by TSP-1 inhibits in vitro angiogenesis stimulated by vascular endothelial growth factor-A (VEGF-A). To demonstrate that the TSP-1 inhibitory signal was mediated by CD36, we transduced CD36 in CD36-deficient endothelial cells. Both TSP-1 and the agonist anti-CD36 mAb SMO, which mimics TSP-1 activity, reduced the VEGF-A165-induced migration and sprouting of CD36-ECs. To address the mechanisms by which CD36 may exert its angiostatic function, we investigated the functional components of the C-terminal cytoplasmic tail by site-directed mutagenesis. Our results indicate that C464, R467, and K469 of CD36 are required for the inhibitory activity of TSP-1. In contrast, point mutation of C466 did not alter TSP-1 ability to inhibit EC migration and sprouting. Moreover, we show that activation of CD36 by TSP-1 down-modulates the VEGF receptor-2 (VEGFR-2) and p38 mitogen-associated protein kinase phosphorylation induced by VEGF-A165, and this effect was specifically abolished by point mutation at C464. These results identify specific amino acids of the C-terminal cytoplasmic tail of CD36 crucial for the in vitro angiostatic activity of TSP-1 and extend our knowledge of regulation of VEGFR-2-mediated biological activities on ECs.  (+info)

T2-TrpRS inhibits preretinal neovascularization and enhances physiological vascular regrowth in OIR as assessed by a new method of quantification. (5/25)

PURPOSE: A carboxyl-terminal fragment of tryptophan tRNA synthetase (T2-TrpRS) has demonstrated potent angiostatic activity during retinal developmental neovascularization in vivo. The effects of T2-TrpRS on pathologic neovascularization were tested and compared with a potent VEGF antagonist using the mouse model of oxygen-induced retinopathy (OIR). METHODS: C57BL/6J mice were transiently exposed to hyperoxic conditions (75% O2) between postnatal day 7 (P7) and P12 and then returned to room air. Retinas were isolated, blood vessels stained with isolectin Griffonia simplicifolia, images of retinal whole-mounts acquired, and the area of vascular obliteration and extent of preretinal neovascularization quantified. This method was compared to the commonly used method of OIR quantification in which the number of pre-inner limiting membrane (ILM) nuclei is counted in serial sections of whole eyes. To assess the angiostatic activity of T2-TrpRS, mice were injected intravitreally at P12 with either T2-TrpRS, a VEGF aptamer, or vehicle (PBS) alone, and the effects on area of obliteration and on preretinal neovascular tuft formation were assessed. RESULTS: Using a modified method of quantification in the mouse OIR model based on images of isolectin-stained retinal wholemounts, we were able to assess reliably and consistently both vascular obliteration and preretinal neovascular tuft formation in the same specimen. T2-TrpRS demonstrated potent angiostatic activity, reducing the appearance of pathologic neovascular tufts by up to 90%. Surprisingly, T2-TrpRS also enhanced physiological revascularization of the obliterated retinal vasculature, reducing these areas by up to 60% compared with PBS-injected eyes. In contrast, the VEGF antagonist, while similarly reducing preretinal neovascular tuft formation, did not enhance revascularization of the obliterated areas. CONCLUSIONS: Use of a rapid, quantifiable method to assess the effect of T2-TrpRS on retinal angiogenesis in the OIR model demonstrates the importance of a quantification system that permits simultaneous analysis of a drug's effect on vascular obliteration as well as on preretinal neovascularization. The results obtained using this method suggest enhanced clinical value for compounds such as T2-TrpRS that not only inhibit pathologic neovascularization, but also facilitate physiological revascularization of ischemic tissue.  (+info)

Endorepellin, the C-terminal angiostatic module of perlecan, enhances collagen-platelet responses via the alpha2beta1-integrin receptor. (6/25)

Endorepellin, a C-terminal fragment of the vascular basement membrane proteoglycan perlecan, inhibits angiogenesis via the alpha2beta1-integrin receptor. Because this integrin is also implicated in platelet-collagen responses and because endorepellin or its fragments are generated in response to injury and inflammation, we hypothesized that endorepellin could also affect platelet biology. We discovered that endorepellin supported alpha2beta1-dependent platelet adhesion, without appreciably activating or aggregating platelets. Notably, endorepellin enhanced collagen-evoked responses in platelets, in a src kinase-dependent fashion, and enhanced the collagen-inhibitory effect of an alpha2beta1-integrin function-blocking antibody. Collectively, these results suggest that endorepellin/alpha2beta1-integrin interaction and effects are specific and dependent on cell type, differ from those emanated by exposure to collagen, and may be due to cellular differences in alpha2beta1-integrin activation/ligand affinity state. These studies also suggest a heretofore unrecognized role for angiostatic basement membrane fragments in platelet biology.  (+info)

Clinical implications of angiogenesis in cancers. (7/25)

Angiogenesis plays an important role in the growth and progression of cancer. The regulation of tumor angiogenesis depends on a net balance of angiogenic factors and antiangiogenic factors, which are secreted by both tumor cells and host-infiltrating cells. Numerous studies have indicated that assessment of angiogenic activity by either microvessel density or expression of angiogenic factors in cancer can provide prognostic information independent of conventional clinicopathological factors such as tumor staging. Some studies also suggested that assessment of tumor angiogenesis may predict cancer response to chemotherapy or radiotherapy. However, the most important clinical implication of tumor angiogenesis is the development of a novel strategy of anticancer therapy targeting tumor vessels instead of cancer cells. Antiangiogenic therapy aims to inhibit the growth of tumor, and current evidence suggests that it works best in combination with conventional cytotoxic chemotherapy. Recently, a monoclonal antibody against vascular endothelial growth factor, which is one of the most potent angiogenic factors, has been approved for clinical use in colorectal cancer patients after a clinical trial confirmed that combining the antibody with standard chemotherapy regimen could prolong patient survival. The clinical implications of angiogenesis in cancer are reviewed in this article.  (+info)

Stimulation of angiostatic platelet factor-4 variant (CXCL4L1/PF-4var) versus inhibition of angiogenic granulocyte chemotactic protein-2 (CXCL6/GCP-2) in normal and tumoral mesenchymal cells. (8/25)

Chemokines affect inflammation and cancer through leukocyte attraction and angiogenesis. Here, we demonstrate that CXCL4L1/platelet factor-4 variant (PF-4var), a highly angiostatic chemokine, is poorly chemotactic for phagocytes and is inducible in monocytes by inflammatory mediators but remained undetectable in macrophages and neutrophils. In addition, CXCL4L1/PF-4var production by mesenchymal tumor cells was evidenced in vitro and in vivo by specific ELISA and immunohistochemistry. CXCL4L1/PF-4var, but not CXCL4/PF-4, was coinduced with the angiogenic chemokine CXCL6/granulocyte chemotactic protein-2 (GCP-2) by cytokines, e.g., IL-1beta and IL-17, in sarcoma cells, but not in diploid fibroblasts. Furthermore, the induction of CXCL6/GCP-2 in endothelial cells by IL-1beta was enhanced synergistically by TNF-alpha but inhibited by IFN-gamma, which synergized with IL-1beta to produce the angiostatic CXCL10/IFN-gamma-induced protein-10. These findings indicate that the equilibrium between angiostatic and angiogenic factors during inflammation and tumor progression is rather complex and differs depending on the chemokine, cell type, and stimulus. Selective intervention in the chemokine network may drastically disturb this delicate balance of angiogenesis and tissue repair. Application of angiostatic CXCL4L1/PF-4var without attraction of protumoral phagocytes may be beneficial in cancer therapy.  (+info)

Here, we report the FGF2 antagonist and antiangiogenic activity of novel sulfated derivatives of the Escherichia coli K5 polysaccharide. K5 polysaccharide was chemically sulfated in N- and/or O-position after N-deacetylation. O-Sulfated and N,O-sulfated K5 derivatives with a low degree and a high degree of sulfation compete with heparin for binding to 125I-FGF2 with different potency. Accordingly, they abrogate the formation of the HSPG-FGF2-FGFR ternary ...
Chemokines belong to a class of pro-inflammatory cytokines that have the ability to attract and activate leukocytes. Their name is derived from chemotactic cytokines based on their ability to induce and mediate chemotaxis in nearby responsive cells. Formerly, they were called SIS family of cytokines, SIG family of cytokines, SCY family of cytokines, Platelet factor-4 superfamily or intercrines. Chemokines can be divided into at least four structural branches: c (chemokines, c), cc (chemokines, cc), cx3c (chemokines, cx3c), and cxc (chemokines, cxc). The classification is according to the variations in a shared cysteine motif. Chemokines may also be classified based on their functions. Homeostatic chemokines are chemokines that are responsible for basal leukocyte migration. Examples of homeostatic chemokines are CCL14, CCL19, CCL20, CCL21, CXCL12 and CXCL13. Nevertheless, some of them are not exclusive to this function. For instance, CCL20 is also associated with inflammation since it can act as ...
Chemokines (Greek -kinos, movement) are a family of small cytokines, or signaling proteins secreted by cells. Their name is derived from their ability to induce directed chemotaxis in nearby responsive cells; they are chemotactic cytokines. Cytokine proteins are classified as chemokines according to behavior and structural characteristics. In addition to being known for mediating chemotaxis, chemokines are all approximately 8-10 kilodaltons in mass and have four cysteine residues in conserved locations that are key to forming their 3-dimensional shape. These proteins have historically been known under several other names including the SIS family of cytokines, SIG family of cytokines, SCY family of cytokines, Platelet factor-4 superfamily or intercrines. Some chemokines are considered pro-inflammatory and can be induced during an immune response to recruit cells of the immune system to a site of infection, while others are considered homeostatic and are involved in controlling the migration of ...
In the present study, it was demonstrated that IL-17A could stimulate the secretion of angiogenic CXC chemokines from liver cancer cells, which may recruit endothelial cells to the tumor cells in a CXCR2-dependent manner. Tumor angiogenesis was also promoted by IL-17A expression in vivo. The CXC chemokines can be classified as angiogenic or angiostatic predominantly based on the presence or absence of an ELR motif. The angiogenic CXC chemokines include CXCL1, CXCL2, CXCL3, CXCL5, CXCL6, CXCL8 and CXCL12, and the angiostatic chemokines include CXCL4, CXCL9, CXCL10, CXCL11 and CXCL14 (21). IL-17A was shown to increase the expression of CXCL1, CXCL2, CXCL3, CXCL5, CXCL6 and CXCL8 in Huh7.5 cells and upregulated CXCL2 in HepG2 cells. Additionally, angiostatic CXC chemokines were not affected by IL-17A in both cell lines. IL-17A has been reported to stimulate VEGFA production and promote angiogenesis in several cancer cell lines (16-18) and it has been shown previously that IL-17A does not affect ...

In the Mouse Antithrombotic Assay aspirin (30-300 mg/kg) protected mice from death by 15 and 42%, respectively. Four Ca++ channel blockers (nitrendipine, nicardipine, nifedipine and verapamil) were effective in reducing the mortality. At the dose of 100 mg/kg nitrendipine and nicardipine gave 80 and 85% protection respectively. Whereas aspirin almost suppressed completely thromboxane (Tx)B2 and platelet factor-4 release after collagen-epinephrine infusion, neither nitrendipine nor nicardipine modified TxB2 release and only reduced slightly platelet factor-4 release. The treatment with aspirin, nitrendipine or nicardipine did not counteract the fall in circulating platelets counted 1 min after the aggregation challenge, but at 3 min platelet count was significantly higher in aspirin-treated mice than in animals given either Ca++ channel blocker. Mouse platelet aggregation induced in vitro by the combination of collagen and epinephrine was inhibited in samples obtained from mice pretreated with ...
To examine whether the lack of sufficient neoangiogenesis in systemic sclerosis (SSc) is caused by a decrease in angiogenic factors and/or an increase in angiostatic factors, the potent proangiogenic molecules vascular endothelial growth factor (VEGF) and basic fibroblast growth factor, and the angiostatic factor endostatin were determined in patients with SSc and in healthy controls. Forty-three patients with established SSc and nine patients with pre-SSc were included in the study. Serum levels of VEGF, basic fibroblast growth factor and endostatin were measured by ELISA. Age-matched and sex-matched healthy volunteers were used as controls. Highly significant differences were found in serum levels of VEGF between SSc patients and healthy controls, whereas no differences could be detected for endostatin and basic fibroblast growth factor. Significantly higher levels of VEGF were detected in patients with Scl-70 autoantibodies and in patients with diffuse SSc. Patients with pre-SSc and short ...
Background: Sepsis-associated disseminated intravascular coagulation (SAC) is associated with marked hemostatic changes including transient thrombocytopenia due to their enodogenous activation / consumption. The widespread activation of platelets contribute to vascular occlusions, fibrin deposition, multi-organ dysfunction, contributing to a two-fold increase in mortality.. Aims: The purpose of this study was to measure markers of platelet function in the plasma of patients with clinically established SAC and to determine their association to disease severity and outcome.. Methods: Plasma samples from 103 adult intensive care unit (ICU) patients with sepsis and suspected disseminated intravascular coagulation (DIC) were acquired from the University of Utah Hospital at the time of admission. Samples were shipped to Loyola University Chicago and stored at -80˚C prior to analysis.

Neutrophil-activating protein-2 (NAP-2) is a 72 residue protein demonstrating a range of proinflammatory activities. The solution structure of monomeric NAP-2 has been investigated by two-dimensional 1H-n.m.r. spectroscopy. Sequence-specific proton resonance assignments have been made and secondary structural elements have been identified on the basis of nuclear Overhauser data, coupling constants and amide hydrogen/deuteron exchange. The NAP-2 monomer consists of a triple-stranded anti-parallel beta-sheet arranged in a Greek key and a C-terminal helix (residues 59-70) and is very similar to that found in the n.m.r. solution conformation of dimeric interleukin-8 and the crystal structure of tetrameric bovine platelet factor-4. Results are discussed in terms of heparin binding and neutrophil-activation properties of NAP-2. ...

Platelet factor 4 (PF4) is a small cytokine belonging to the CXC chemokine family that is also known as chemokine (C-X-C motif) ligand 4 (CXCL4) . This chemokine is released from alpha-granules of activated platelets during platelet aggregation, and promotes blood coagulation by moderating the effects of heparin-like molecules. Due to these roles, it is predicted to play a role in wound repair and inflammation. It is usually found in a complex with proteoglycan. The gene for human PF4 is located on human chromosome 4. Platelet factor-4 is a 70-amino acid protein that is released from the alpha-granules of activated platelets and binds with high affinity to heparin. Its major physiologic role appears to be neutralization of heparin-like molecules on the endothelial surface of blood vessels, thereby inhibiting local antithrombin III activity and promoting coagulation. As a strong chemoattractant for neutrophils and fibroblasts, PF4 probably has a role in inflammation and wound repair. PF4 is ...

Dr. Maniscalco studies pulmonary microvascular development in lung injury. Using various animal models, including a non-human primate model of BPD, this work examines the effects of oxygen and ventilation of immature lung on the development of alveolar capillaries. The major goals of the research are to characterize microvascular development in lung injury and investigate angiogenic and angiostatic regulators in normal and injured lung. Recent work has linked expression of inflammatory CXC chemokine mediators, which regulate angiogenesis and are part of the pathophysiology of BPD, to impaired lung microangiogenesis. ...
This issue contains an important contribution from the team of Douglas Lauffenburger, Chair of the Editorial Board, at MIT, USA, in which they demonstrate the ability to characterise quantitative data on phenotypic behaviour of individual endothelial cells in response to angiogenesis signalling and relate it to overall population behaviour. They show that the behaviour of microvascular endothelial cells in a single population is heterogeneous and cannot be assumed to be the same for all cells in a given condition.. Endothelial cell phenotypic behaviors cluster into dynamic state transition programs modulated by angiogenic and angiostatic ...
microRNA-21 (miR-21) is the most commonly upregulated miRNA in solid tumors. This cancer-associated microRNA (oncomiR) regulates various downstream effectors associated with tumor pathogenesis during all stages of carcinogenesis. In this study, we analyzed the function of miR-21 in noncancer cells of the tumor microenvironment to further evaluate its contribution to tumor progression. We report that the expression of miR-21 in cells of the tumor immune infiltrate, and in particular in macrophages, was responsible for promoting tumor growth. Absence of miR-21 expression in tumor- associated macrophages (TAMs), caused a global rewiring of their transcriptional regulatory network that was skewed toward a proinflammatory angiostatic phenotype. This promoted an antitumoral immune response characterized by a macrophage-mediated improvement of cytotoxic T-cell responses through the induction of cytokines and chemokines, including IL-12 and C-X-C motif chemokine 10. These effects translated to a ...

Treatment of patients with the VEGFR TKIs sorafenib and sunitinib can lead to periods of tumor stability, but resistance to therapy is inevitable. We used a mouse model to define mechanisms by which resistance develops and found that components of the IFNγ signaling pathway are lost with sunitinib or sorafenib therapy. Our data also show that CXCL9 treatment delays resistance to sunitinib in 786-O- and A498-derived tumors and that one mechanism by which this occurs is by prolongation of the antiangiogenic effects of sunitinib. These data suggest that angiostatic pathways are suppressed as a result of VEGFR TKI therapy and set the stage for the subsequent development of resistance to therapy.. In the setting of VEGFR inhibition, RCC tumors undergo extensive necrosis (22). In the setting of this necrosis and accompanying hypoxia/nutrient deprivation, tumors may undergo compensatory changes, including the induction of salvage angiogenesis pathways. We propose that the environmental stress ...
Treatment of metastatic renal cell cancer (RCC) with antiangiogenic agents that block vascular endothelial growth factor (VEGF) receptor 2 signaling produces tumor regression in a substantial fraction of patients; however resistance typically develops within 6-12 months. The purpose of this study was to identify molecular pathways involved in resistance. Treatment of mice bearing either 786-0 or A498 human RCC xenografts with sorafenib or sunitinib produced tumor growth stabilization followed by regrowth despite continued drug administration analogous to the clinical experience. Tumors and plasma were harvested at day 3 of therapy and at the time of resistance to assess pathways that may be involved in resistance. Serial perfusion imaging, and plasma and tumor collections were obtained in mice treated with either placebo or sunitinib alone or in combination with intratumoral injections of the angiostatic chemokine CXCL9. Sunitinib administration led to an early down-modulation of interferon ...
