    Abstract Thromboembolism is one of the most common causes of death in cancer patients. Among the most frequent thrombotic complications in patients with cancer are disseminated intravascular coagulation, thrombotic thrombocytopenic purpura, and thrombocytosis. Clearly, these complications arise as tumor cells interact with almost all components of the hemostatic system including platelets. Platelets participate in tumor progression by contributing to the metastatic cascade, protecting tumor cells from immune surveillance, regulating tumor cell invasion, and angiogenesis. Platelets contain one of the largest stores of angiogenic and mitogenic factors and the tumor vasculature is leaky, which allows platelets to come in contact with the tumor and deposit multiple angiogenic factors including vascular endothelial growth factor (VEGF) and thrombin to tumor cells, which in turn contributes to tumor progression. This article reviews the recent literature on how platelets contribute to tumor growth, angiogenesis, and metastasis.

    Abstract The critical pathogenic role of tumor necrosis factor (TNF)alpha in inflammatory disorders such as rheumatoid arthritis and inflammatory bowel disease is well established. The role played by TNFalpha in both the treatment and pathogenesis of cancer remains less understood. Recent advances help to create a framework for understanding seemingly paradoxical effects of TNFalpha as both an anti-tumour agent and a mediator of tumour growth. High pharmacological doses of TNFalpha combined with chemotherapy can regress otherwise intractable tumours, and efforts continue to optimize delivery to avoid severe toxicities. Mounting evidence demonstrates that pathophysiological concentrations of endogenous TNFalpha act to promote tumour genesis and growth. The cellular and molecular pathways mediating these phenomena are starting to be clarified. Current data support the continued development of both TNFalpha and anti-TNFalpha therapy for clinical treatment of cancers in distinct settings.

    Abstract A new paradigm is becoming widely accepted, that chronic inflammation, driven in part by chemokines and cytokines at the site of a tumour, may facilitate tumour progression instead of promoting anti-tumour immunity. Tumours and activated stromal cells secrete pro-inflammatory chemokines and cytokines that act either directly or indirectly through stimulation of the vascular endothelium to recruit leukocytes to the tumour. After activation, these tumour-associated leukocytes release angiogenic factors, mitogens, proteolytic enzymes, and chemotactic factors, recruiting more inflammatory cells and stimulating angiogenesis to sustain tumour growth and facilitate tumour metastasis. Breaking this cycle by inhibiting targets such as cytokines, chemokines and other inflammatory mediators, either alone, or more realistically, in combination with other therapies, such as anti-angiogenic or cytotoxic agents, may provide highly efficacious therapeutic regimens for the treatment of malignancies. This article reviews anti-cytokine and anti-chemokine therapies being pursued in cancer, and discusses in more detail anti-tumour necrosis factor-alpha (TNF) approaches.

    Abstract Matrix metalloproteinases (MMPs) are metal-dependent endopeptidases that play pivotal roles in tumor disease progression. In many solid tumors, MMPs are indeed produced by tumor stromal cells, rather than by tumor cells. This expression pattern is, at least in part, regulated by tumor-stroma interaction via tumor cell-associated extracellular matrix metalloproteinase inducer (EMMPRIN). In vitro, recombinant EMMPRIN dose-dependently stimulated MMP-1 production by primary human fibroblast cells. Interestingly, in addition to stimulating MMP expression, EMMPRIN also induced its own gene expression. To further explore this potential positive feedback regulatory mechanism, we generated human breast cancer cells expressing different levels of EMMPRIN. Coculture of EMMPRIN-positive tumor cells with fibroblast cells resulted in a concomitant stimulation of MMP-2, MMP-9, and EMMPRIN production. This induction was EMMPRIN dependent, was further enhanced by overexpression, and was reduced by antisense suppression of EMMPRIN expression in tumor cells. Increased expression of membrane-associated EMMPRIN was accompanied by an MMP-dependent generation of a soluble form of EMMPRIN representing a proteolytic cleavage product lacking the carboxyl terminus. On the basis of these findings, we propose a model in which tumor cell-associated EMMPRIN stimulates MMPs, as well as EMMPRIN expression in tumor stroma. Increased MMP activity in tumor local environment results in proteolytic cleavage of membrane-associated EMMPRIN, releasing soluble EMMPRIN. Soluble EMMPRIN in turn acts in a paracrine fashion on stroma cells that are both adjacent and distant to tumor sites to further stimulate the production of MMPs and additional EMMPRIN, which consequently contributes to tumor angiogenesis, tumor growth, and metastasis.

    Abstract The alphavbeta3 integrin plays an important role in tumor growth and angiogenesis. Inhibition of this receptor by intact bivalent antibodies has been shown to inhibit angiogenesis and tumor growth. In this study we tested the chimeric Fab of 7E3 (c7E3 Fab), an antibody reactive with human platelet GPIIb/IIIa and alphavbeta3 to determine if it would inhibit in vivo angiogenesis and tumor growth in a SCID mouse/human skin tumor growth and angiogenesis model. c7E3 Fab inhibited human tumor angiogenesis and tumor growth. These data suggest monovalent antibody fragments devoid of antibody effector function can have efficacy in preclinical models of angiogenesis.

    Abstract Treatment with c7E3 (abciximab, ReoPro) has been associated with a reduction in coronary events and the need for revascularization. Some of these beneficial effects may be due to blockade of the αvβ3 integrin receptor on smooth muscle cells (SMCs), however very little is known about the mechanisms involved. The current studies were designed to test the hypothesis that β3 integrin antagonists inhibit the arterial response to injury by reducing matrix metalloproteinase (MMP) activity in the vessel wall. Male Sprague-Dawley rats were treated with daily intraperitoneal injections of the monoclonal antibody m7E3 at a dose of 6 mg/kg/day. MMP-9 activity was reduced by 73%, and MMP-2 activity by 75%, in the injured carotids of the m7E3-treated rats compared to saline-treated controls. By contrast, tissue inhibitor metalloproteinase (TIMP) activity was not changed. SMC migration assayed at 4 days after injury was reduced from 56.7 ± 14 cells/mm2 intimal surface area in controls to 17.5 ± 5 cells/mm2 in m7E3-treated rats (p = 0.02). Medial cell replication measured at 4 days and intimal cell replication measured at 7 days were not affected. Intimal cross-sectional area, measured 14 days after injury was reduced by 28% after m7E3 treatment (p = 0.05). Intimal smooth muscle cell number and the ratio of intima/media cross-section area were also reduced. By contrast, intimal SMC density was not affected by m7E3 treatment, indicating no effect on matrix accumulation. We conclude that treatment with m7E3 reduced SMC migration following vascular injury, possibly via an inhibitory effect on MMP activity, and this resulted in a decrease in intimal size at 14 days after injury.

    Abstract Abciximab is the first of a new class of therapeutic agents that specifically block the function of the platelet cell adhesion receptor, glycoprotein (GP) IIb/IIIa and the subsequent platelet aggregation that contributes to thrombosis. Abciximab displays high avidity for the GPIIb/IIIa receptor, which results in a prolonged platelet-bound half-life, and a sustained duration of platelet inhibition resulting from the redistribution and equilibration of abciximab molecules among circulating platelets at gradually diminishing levels of GPIIb/IIIa receptor occupancy. In contrast to its extended platelet bound life-span, unbound abciximab is cleared rapidly (half-life <10 min) after an intravenous bolus dose. Nevertheless, a subsequent continuous infusion that maintains relatively low concentrations of free abciximab (50 to 100 ng/ml) sustains the pharmacologic GPIIb/IIIa receptor blockade throughout the duration of treatment. In addition, abciximab also interacts with other potentially important biological targets. The agent binds with equal affinity to the other β 3 containing integrin, the vitronectin (α v β 3 ) receptor, and more weakly to the leukocyte Mac-1 receptor. The high avidity and multi-receptor specificity of abciximab are consistent both short- and long-term therapeutic benefits in patients with acute coronary syndromes.
