    摘要: An endemic peripheral vascular disorder due to chronic arsenic poisoning, named Blackfoot disease (BFD), occurs in Taiwan. BFD causes destruction of vascular endothelial cells, and an anti-endothelial cell IgG antibody was found in the sera of BFD patients. We studied the role of this IgG antibody (BFD-IgG) in modulating proliferation and angiogenesis of human umbilical vein endothelial cells (HUVECs) and found that a low concentration of BFD-IgG (200?μg/mL) stimulated endothelial cell growth and increased expressions of vascular cell adhesion molecule-1 (VCAM-1), nerve growth factor (NGF), and vascular endothelial growth factor (VEGF). The apoptosis events appeared not altered by addition of BFD-IgG. An in vitro neoangiogenesis assay demonstrated that BFD-IgG promoted the formation of tube-like structures, which was completely abrogated by anti-VEGF neutralizing antibody and partially by NOS inhibitor, L-NAME. We conclude that BFD-IgG at 200?μg/mL results in cell proliferation and enhanced VEGF-dependent angiogenesis in vitro. Those results suggested that a low concentration of BFD-IgG plays a protective role in the pathogenesis or the progression of BFD. ? 2008 Elsevier Inc. All rights reserved.
