【 摘 要 】

References(38)Cited-By(17)Visceral adipose tissue-derived serine protease inhibitor (vaspin) has been recently identified as an adipocytokine in a rat model of type 2 diabetes. Adipocytokines may directly influence the function of endothelial cells (ECs) and modulate inflammatory states. We therefore assessed the effects of vaspin on basal and TNF-α-stimulated human umbilical vein ECs. Vaspin (10-100 ng/ml, 24 hr) had no effects on both basal ECs morphology and TNF-α-induced (10 ng/ml, 24 hr) morphological damages. Vaspin did not inhibit the TNF-α (20 min) activation of JNK, p38 and NF-κB, but only slightly inhibited Akt. Furthermore, vaspin did not decrease the TNF-α (24 hr) induction of vascular cell adhesion molecule-1, intercellular adhesion molecule-1, endothelial selectin, and cyclooxygenase-2 protein expression as well as monocyte chemotactic protein-1, tissue factor, and plasmogen activator inhibitor-1 mRNA expression. The present results indicate that vaspin has no effects on normal ECs, and can not prevent TNF-α-induced inflammatory injury.
