Reduction of monocyte chemoattractant protein-1 and interleukin-8 levels by ticlopidine in TNF-alpha stimulated human umbilical vein endothelial cells. J Biomed Biotechnol 2010; 2009:917837.

Abstract
Atherosclerosis and its associated complications represent major causes of morbidity and mortality in the industrialized or Western countries. Monocyte chemoattractant protein-1 (MCP-1) is critical for the initiating and developing of atherosclerotic lesions. Interleukin-8 (IL-8), a CXC chemokine, stimulates neutrophil chemotaxis. Ticlopidine is one of the antiplatelet drugs used to prevent thrombus formation relevant to the pathophysiology of atherothrombosis. In this study, we found that ticlopidine dose-dependently decreased the mRNA and protein levels of TNF-α-stimulated MCP-1, IL-8, and vascular cell adhesion molecule-1 (VCAM-1) in human umbilical vein endothelial cells (HUVECs). Ticlopidine declined U937 cells adhesion and chemotaxis as compared to TNF-α stimulated alone. Furthermore, the inhibitory effects were neither due to decreased HUVEC viability, nor through NF-kB inhibition. These results suggest that ticlopidine decreased TNF-α induced MCP-1, IL-8, and VCAM-1 levels in HUVECs, and monocyte adhesion. Therefore, the data provide additional therapeutic machinery of ticlopidine in treatment and prevention of atherosclerosis.

Abstract
A multilayered silk fibroin protein coating system was employed as a drug carrier and delivery system to evaluate vascular cell responses to heparin, paclitaxel, and clopidogrel. The results demonstrated that the silk coating system was an effective system for drug-eluting coatings, such as for stent applications, based on its useful micromechanical properties and biological outcomes. Cell attachment and viability studies with human aortic endothelial cells (HAECs) and human coronary artery smooth muscle cells (HCASMCs) on the drug-incorporated silk coatings demonstrated that paclitaxel and clopidogrel inhibited smooth muscle cell (SMC) proliferation and retarded endothelial cell proliferation. Heparin-loaded silk multilayers promoted HAEC proliferation while inhibiting HCASMC proliferation, desired outcomes for the prevention of restenosis. The preservation of the phenotype of endothelial cells on silk and heparin-loaded silk coatings was confirmed with the presence of endothelial markers CD-31, CD-146, vWF and VE-Cadherin using immunocytochemistry assays. A preliminary in-vivo study in a porcine aorta showed integrity of the silk coatings after implantation and the reduction of platelet adhesion on the heparin-loaded silk coatings.

Abstract
BACKGROUND Cell migration is a complex phenomenon that requires the coordination of numerous cellular processes. Investigation of cell migration and its underlying biology is of interest to basic scientists and those in search of therapeutics. Current migration assays for screening small molecules, siRNAs, or other perturbations are difficult to perform in parallel at the scale required to screen large libraries. RESULTS We have adapted the commonly used scratch wound healing assay of tissue-culture cell monolayers to a 384 well plate format. By mechanically scratching the cell substrate with a pin array, we are able to create characteristically sized wounds in all wells of a 384 well plate. Imaging of the healing wounds with an automated fluorescence microscope allows us to distinguish perturbations that affect cell migration, morphology, and division. Readout requires ~1 hr per plate but is high in information content i.e. high content. We compare readouts using different imaging technologies, automated microscopy, scanners and a fluorescence macroscope, and evaluate the trade-off between information content and data acquisition rate. CONCLUSIONS The adaptation of a wound healing assay to a 384 well format facilitates the study of aspects of cell migration, tissue reorganization, cell division, and other processes that underlie wound healing. This assay allows greater than 10,000 perturbations to be screened per day with a quantitative, high-content readout, and can also be used to characterize small numbers of perturbations in detail.

Anti-angiogenic effects of the thienopyridine SR 25989 in vitro and in vivo in a murine pulmonary metastasis model. Br J Cancer 2002; 86:803-10.

Abstract
Neovascularisation is a key step in tumour growth and establishment of distant metastases. We have recently demonstrated that the thienopyridine SR 25989 an enantiomer of the anti-aggregant clopidogrel (Plavix) lacking anti-aggregant activity, inhibits endothelial cell proliferation in vitro by increasing the expression of endogenous thrombospondin-1, a natural potent inhibitor of angiogenesis. The anti-angiogenic effect of SR 25989 was further assessed in vitro in a quantitative assay of angiogenesis comprising a fragment of rat aorta embedded in a fibrin gel and in vivo in a pulmonary metastatic model using C57BL/6 mice inoculated in the foot pad with the highly metastatic melanoma cell line B16 F10. SR 25989 induced a dose dependent inhibition of spontaneous microvessel development in vitro reaching half maximal inhibition at around less than 50 microM and caused platelet derived growth factor induced angiogenesis to regress as a function of thienopyridine concentration. In vivo, SR 25989 did not alter significantly the growth rate of the primary tumour in the foot pad and did not inhibit development of inguinal nodes which appeared after amputation. However, the number and size of lung metastases were reduced in treated animals when examined at the time of sacrifice. In addition, the few metastases over 1 mm3 did not show any neovascularisation, as confirmed by negative von Willebrand immunostaining and in contrast to intense vascularisation seen in metastases developed by control mice. These results confirm that SR 25989 possesses potent anti-angiogenic properties and is able to inhibit metastatic dissemination and growth. The lack of effect on the primary tumour and inguinal nodes illustrates the complexity of the mechanisms involved in tumoural neo-angiogenesis and points out the possibility for distinct processes leading to neovascularisation in primary tumour as opposed to metastases.

Abstract
Bleeding and delayed healing of ulcers are well recognized clinical problems associated with the use of aspirin and other nonsteroidal antiinflammatory drugs, which have been attributed to their antiaggregatory effects on platelets. We hypothesized that antiplatelet drugs might interfere with gastric ulcer healing by suppressing the release of growth factors, such as vascular endothelial growth factor (VEGF), from platelets. Gastric ulcers were induced in rats by serosal application of acetic acid. Daily oral treatment with vehicle, aspirin, or ticlopidine (an ADP receptor antagonist) was started 3 days later and continued for 1 week. Ulcer induction resulted in a significant increase in serum levels of VEGF and a significant decrease in serum levels of endostatin (an antiangiogenic factor). Although both aspirin and ticlopidine markedly suppressed platelet aggregation, only ticlopidine impaired gastric ulcer healing and angiogenesis as well as reversing the ulcer-associated changes in serum levels of VEGF and endostatin. The effects of ticlopidine on ulcer healing and angiogenesis were mimicked by immunodepletion of circulating platelets, and ticlopidine did not influence ulcer healing when given to thrombocytopenic rats. Incubation of human umbilical vein endothelial cells with serum from ticlopidine-treated rats significantly reduced proliferation and increased apoptosis, effects reversed by an antibody directed against endostatin. Ticlopidine treatment resulted in increased platelet endostatin content and release. These results demonstrate a previously unrecognized contribution of platelets to the regulation of gastric ulcer healing. Such effects likely are mediated through the release from platelets of endostatin and possibly VEGF. As shown with ticlopidine, drugs that influence gastric ulcer healing may do so in part through altering the ability of platelets to release growth factors.

Abstract
CD9, a widely expressed membrane protein of the tetraspanin family, has been implicated in diverse functions, such as signal transduction, cell adhesion, and cell motility. We tested the effects of an anti-CD9 monoclonal antibody (ALMA.1) on the migration and proliferation of human vascular endothelial cells (ECs) during repair of an in vitro mechanical wound mimicking angiogenic processes. ALMA.1 induced dose-dependent inhibition of wound repair with a 35+/-1.5% decrease at 20 microg/mL. Only cell migration was affected, because the rate of proliferation of ECs at the lesion margin was not modified and because the inhibition of repair was also observed for nonproliferating irradiated ECs. Monoclonal antibodies against CD63 tetraspanin (H5C6) and control mouse IgG (MOPC-21) were inactive. CD9, one of the most abundant proteins at the surface of ECs, colocalized with beta(1) or beta(3) integrins on EC membranes in double-labeling immunofluorescence experiments with ALMA.1 and an anti-beta(1) (4B4) or anti-beta(3) (SDF.3) monoclonal antibody. Moreover, ALMA.1 and 4B4 had additive inhibitory effects on lesion repair, whereas 4B4 alone also inhibited EC proliferation. In transmembrane Boyden-type assays, ALMA.1 induced dose-dependent inhibition of EC migration toward fibronectin and vitronectin with 45+/-6% and 31+/-10% inhibition, respectively, at 100 microg/mL. 4B4 inhibited migration toward fibronectin at 10 microg/mL but had no effect in the case of vitronectin. Adhesion of ECs to immobilized anti-CD9 monoclonal antibodies induced tyrosine-phosphorylated protein levels similar to those observed during interactions with beta(1) or beta(3) integrins. These results point to the involvement of CD9 in EC adhesion and migration during lesion repair and angiogenesis, probably through cooperation with integrins. As such, CD9 is a potential target to inhibit angiogenesis in metastatic and atherosclerotic processes.
