Vascular smooth muscle cells (VSMCs) are indispensible components in foam cell formation. Salusin-β is a stimulator in the progression of atherosclerosis. Here, we showed that salusin-β increased foam cell formation evidenced by accumulation of lipid droplets and intracellular cholesterol content, and promoted monocyte adhesion in human VSMCs. Salusin-β increased the expressions and activity of...

The transient regulation of very late antigen (VLA)-4 avidity by CC chemokines may promote chemotaxis of monocytes across VCAM-1-bearing barriers, whereas late and prolonged activation of VLA-5 may mediate subsequent localization in the extracellular matrix. We demonstrate that interactions of VLA-4 with VCAM-1, fibronectin, or a 40-kDa fragment but not a 120-kDa fragment of fibronectin support...

Previously, we have suggested that vascular cell adhesion molecule-1 (VCAM-1) and its integrin receptor alpha4beta1 mediate cell-cell interactions important for skeletal myogenesis. Expression of the receptors subsequently subsides in muscle after birth. Here, we examine the mechanism regulating VCAM-1 gene expression in muscle. An enhancer located between the TATA box and the transcriptional s...

The aim of this study was to investigate the expression level of vascular cell adhesion molecule-1 (VCAM-1) in the aortic tissues of atherosclerotic patients and to explore the associated clinical implications. Full-thickness aortic wall tissue samples were collected from atherosclerotic patients. Biochemical analysis was used for the detection of the serum levels of triglycerides (TG), total c...

Acute chest syndrome (ACS) is a leading cause of death in sickle cell disease (SCD). Our previous work showed that hypoxia enhances the ability of sickle erythrocytes to adhere to human microvessel endothelium via interaction between very late activation antigen-4 (VLA4) expressed on sickle erythrocytes and the endothelial adhesion molecule vascular cell adhesion molecule-1 (VCAM-1). Additional...

In this study, we examined the effect of Cd on the expression of vascular cell adhesion molecule-1 (VCAM-1) and its mechanisms in bEnd.3 cells. The treatment with Cd increased protein and mRNA expressions of VCAM-1 and increased the phosphorylations of p38, JNK, and ERK. The Cd-induced VCAM-1 expression was significantly suppressed by either a specific p38 mitogen-activated protein kinase (MAPK...

The objectives of this study were to assess the role of the inducible isoform of nitric oxide synthase (iNOS) on vascular cell adhesion molecule 1 (VCAM-1) expression in vivo in an acute model of inflammation induced in iNOS-deficient (iNOS-/-) mice and compare these data to those obtained by pharmacological inhibition of iNOS in a CD4+ T lymphocyte-dependent model of chronic colitis. VCAM-1 ex...

Platelet-derived growth factor BB (PDGFBB) has been shown to activate the migration of bone marrow-derived mesenchymal stem cells (BM-MSCs), and to contribute to mediating the tropism of BM-MSCs towards gliomas. However, the exact mechanism of this migratory behavior remains to be elucidated. The present study investigated the role of vascular cell adhesion molecule-1 (VCAM-1) in the PDGFBB-ind...

Vascular cell adhesion molecule-1 (VCAM-1) is expressed on vascular endothelium in a variety of inflammatory conditions and mediates leukocyte recruitment from blood into tissues. In this study we report a novel role for VCAM-1 in the formation of the umbilical cord and placenta during development. The murine VCAM1 gene was disrupted by targeted homologous recombination, and a distinct phenotyp...
