چکیده انگلیسی
CXCL16 is a unique chemokine with characteristics as a receptor for phosphatidylserine and oxidized low density lipoproteins in macrophages, and is involved in the accumulation of cellular cholesterol during atherosclerotic lesion development. In this study, we report a new function of CXCL16 as a novel angiogenic factor in human umbilical vein endothelial cells (HUVEC). CXCL16 stimulated proliferation and chemotaxis of HUVEC in a dose-dependent manner, reaching a maximum at 1Â nM. CXCL16 also significantly induced tube formation of HUVEC on Matrigel. Further, exposure of HUVEC to CXCL16 led to a time- and dose-dependent activation of mitogen-activated protein kinase (ERK1/2), which was completely inhibited by a mitogen-activated protein kinase kinase inhibitor, PD98059. Proliferation and tube formation in response to CXCL16 were also blocked by the pretreatment with PD98059, but not CXCL16-induced chemotaxis. Thus, our data indicate that CXCL16 may act as a novel angiogenic factor for HUVEC and that ERK is involved as an important signaling molecule to mediate its angiogenic effects.
