Cylindromatosis (CYLD) is a deubiquitinase that was initially identified as a tumor suppressor and has recently been implicated in diverse normal physiologic processes. In this study, we have investigated the involvement of CYLD in angiogenesis, the formation of new blood vessels from preexisting ones. We find that knockdown of CYLD expression significantly impairs angiogenesis in vitro in both matrigel-based tube formation assay and collagen-based 3-dimensional capillary sprouting assay. Disruption of CYLD also remarkably inhibits angiogenic response in vivo, as evidenced by diminished blood vessel growth into the angioreactors implanted in mice. Mechanistic studies show that CYLD regulates angiogenesis by mediating the spreading and migration of vascular endothelial cells. Silencing of CYLD dramatically decreases microtubule dynamics in endothelial cells and inhibits endothelial cell migration by blocking the polarization process. Furthermore, we identify Rac1 activation as an important factor contributing to the action of CYLD in regulating endothelial cell migration and angiogenesis. Our findings thus uncover a previously unrecognized role for CYLD in the angiogenic process and provide a novel mechanism for Rac1 activation during endothelial cell migration and angiogenesis.

Abstract Background: DARC (The Duffy antigen receptor for chemokines) is a kind of glycosylated membrane protein that binds to members of the CXC chemokine family associated with angiogenesis and has recently been reported to be implicated in diverse normal physiologic processes. This study aimed to investigate the involvement of DARC in angiogenesis, which is known to generate new capillary blood vessels from preexisting ones. Methods: HDMECs (Human dermal microvascular endothelial cells) were divided into two groups (DARC overexpression group, and control group). We used Brdu staining to detect cell proliferation, and wound healing assay to detect cell migration. Then tube formation assay were observed. Also, western blot and immunofluorescent staining were used to estimate the relationship between DARC and RhoA (Ras homolog gene family, member A). Results: HDMECs proliferation, migration, and tube formation were inhibited significantly when DARC was overexpressed intracellular. DARC impaired microfilament dynamics and intercellular connection in migrating cells, and RhoA activation underlay the effect of DARC on endothelial cell. Furthermore, DARC inhibited the formation of new capillaries in vitro. Conclusion: Our findings revealed the role of DARC in the angiogenic process and provided a novel mechanism for RhoA activation during endothelial cell migration and angiogenesis.
