Sensory nerves in skin are capable of releasing multiple neuropeptides, which modulate inflammatory responses by activating specific cutaneous target cells. Extravasation of particular subsets of leukocytes depends upon the regulated expression of cellular adhesion molecules such as VCAM-1 on microvascular endothelial cells. We examined the direct effect of cutaneous neuropeptides on the expres...

We investigated the effect of photodynamic therapy (PDT) and of an anti-vascular cell adhesion molecule-1 (VCAM-1) monoclonal antibody on the in vivo growth of C6 glioma. Seven days after inoculation with C6 cells, adult male Wistar rats weighing 280-300 g with MRI-confirmed glioma were randomly assigned to 4 groups (N = 15 per group): PDT + VCAM-1 antibody group; PDT group; VCAM-1 antibody gro...

OBJECTIVE To evaluate the intravitreous concentration of vascular cell adhesion molecule (VCAM)-1 in diabetic patients with proliferative diabetic retinopathy (PDR) and the relationship of VCAM-1 with vascular endothelial growth factor (VEGF). RESEARCH DESIGN AND METHODS Serum and vitreous fluid samples were obtained simultaneously at the onset of vitrectomy from 20 diabetic patients with PDR...

BACKGROUND Increased levels of inflammatory markers are predictors of thromboembolic events during atrial fibrillation (AF). Increased endocardial expression of adhesion molecules (ie, vascular cell adhesion molecule [VCAM] and intercellular adhesion molecule [ICAM]) could be an important link between initiation of inflammatory and prothrombogenic mechanisms responsible for thrombus development...

AIM To evaluate the correlation between serum vascular cellular adhesion molecule-1 (VCAM-1) levels and clinicopathological features in patients with hepatocellular carcinoma (HCC). METHODS Ninety-six patients who underwent HCC resection were recruited in the study. Preoperative serum levels of soluble VCAM-1 were measured by enzyme-linked immunosorbent assay. RESULTS Serum VCAM-1 level in ...

Aim: Vascular adhesion molecule 1 (VCAM-1) plays an important role in solid tumor enlargement and/or metastases. This study evaluated the clinical significance of measuring serum levels of soluble VCAM-1 in rectal cancer and aimed to clarify the biologic significance of its local expression. Method: Serum was collected from 90 patients with rectal cancer and 40 healthy volunteers. Cancer tissue...

Vascular cell adhesion molecule-1 (VCAM-1), an inducible cell-cell recognition protein on the endothelial cell surface (EC), has been associated with early stages of atherosclerosis. In view of the accelerated vascular disease observed in patients with diabetes, and the enhanced expression of VCAM-1 in diabetic rabbits, we examined whether irreversible advanced glycation endproducts (AGEs), cou...

We previously established that probucol decreases basal expression of VCAM-1 in the aorta of WHHL rabbits and inhibits the up-regulation of VCAM-1 expression that normally accompanies atherogenesis. To determine whether this effect is shared by other antioxidants in vivo, we now investigated whether a structurally unrelated antioxidant, vitamin E, also inhibits arterial VCAM-1 expression and wh...

BACKGROUND Cardiovascular ischemic events may occur more frequently in hypertensive patients with activated renin-angiotensin systems. We tested the hypothesis that angiotensin II (Ang II) may contribute to atherosclerosis by increasing expression of vascular inflammatory genes such as vascular cell adhesion molecule-1 (VCAM-1). METHODS AND RESULTS Rats infused with norepinephrine or Ang II f...

Endothelial vascular cell adhesion molecule-1 (VCAM-1) is expressed in response to cytokine stimulation and plays a critical role in inflammatory reactions. Previously, we developed a novel VCAM-1 inhibitor that acts through a mechanism independent of nuclear factor-kB activity. It suppresses the binding activity of GATA proteins in cytokine-stimulated endothelial cells, which may be related to...
