Abstract:
The migration of vascular endothelial cells plays a critical role in a variety of vascular physiological and pathological processes, such as embryonic development, angiogenesis, wound healing, re-endothelialization, and vascular remodeling. This study clarified the role and mechanism of a new vascular homeostasis regulator, Cellular repressor of E1A-stimulated genes (CREG), in the migration of primary human umbilical vein endothelial cells (HUVECs). A wound healing assay and transwell migration model showed that upregulation of CREG expression induced HUVEC migration and it was positively correlated with the expression of vascular endothelial growth factor. Furthermore, wild type integrin-linked kinase reversed the poor mobility of CREG knock-down HUVECs; in contrast, kinase-dead integrin-linked kinase weakened the migration of HUVECs. We also studied the effect of CREG on HUVEC migration by the addition of an mTOR inhibitor, recombinant vascular endothelial growth factor(165), neutralizing antibody of vascular endothelial growth factor(165) and AKT siRNA, and we concluded that CREG induces endothelial cell migration by activating the integrin-linked kinase/AKT/mTOR/VEGF(165) signaling pathway.
