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)
