Proinflammatory cytokine (e.g., TNF-alpha)-induced expression of endothelial cell adhesion molecules (ECAMs) on the lumenal surface of the vascular endothelium and a consequent increase in leukocyte adhesion are key aspects of pathological inflammation. A promising therapeutic approach to diminish aberrant leukocyte adhesion is, therefore, to inhibit(More)
PURPOSE To evaluate whether (a) Wnt5a expression in pancreatic cancer and malignant melanoma cells might be associated with constitutive levels of Toll-like receptor 3 (TLR3) and/or TLR3 signaling; (b) phenylmethimazole (C10), a novel TLR signaling inhibitor, could decrease constitutive Wnt5a and TLR3 levels together with cell growth and migration; and (c)(More)
Atherosclerosis (ATH) is a chronic inflammatory disease that involves cascades of signaling events mediated by various effector proteins. Here we sought to determine if the expression of Wnt5a, a secreted glycoprotein, is altered in discrete regions of the arterial plaque. Atherosclerotic plaque tissues from 14 human subjects undergoing elective carotid(More)
OBJECTIVE Wnt5a is a secreted glycoprotein highly present in atherosclerotic lesions. Uptake of oxidized-low density lipoprotein (ox-LDL) by monocytes/macrophages plays a critical role in atherosclerosis. The objective of this study was to determine if Wnt5a mRNA expression correlates with the severity of atherosclerotic lesions, and if, ox-LDL can induce(More)
eukocyte adhesion to the vascular endothelium (the layer of cells that lines the blood vessel walls) plays a central role in normal and pathological inflammation (e.g., host response to infection, wound healing, atherosclerosis, inflammatory bowel disease, and arthritis). This process involves a cascade of adhesive events commonly referred to as initial(More)
Although significant progress has been made in the fight against cancer, successful treatment strategies have yet to be developed to combat those tumors that have metastasized to distant organs. Poor characterization of the molecular mechanisms of cancer spread is a major impediment to designing predictive diagnostics and effective clinical interventions(More)
Previous studies revealed that phenylmethimazole (C10) inhibits IRF3 signaling, preventing dsRNA-induction of type 1 interferon gene expression, production, and downstream signaling. In the present study, we investigated the molecular basis for C10 inhibition of dsRNA-stimulated IRF3 signaling. IRF-3 Trans-AM assays were used to measure C10 effects on dsRNA(More)
A growing body of evidence suggests that L-selectin ligands presented on circulating tumor cells facilitate metastasis by binding L-selectin presented on leukocytes. Commonly used methods for detecting L-selectin ligands on tissues, e.g., immunostaining, are performed under static, no-flow conditions. However, such analysis does not assay for functional(More)
