Gene-targeting studies have shown that Delta-like 4 (Dll4) is required for normal embryonic vascular remodeling, but the mechanisms underlying Dll4 regulatory functions are not well defined. We generated primary human umbilical vascular endothelial cells that express Dll4 protein to study Dll4 function and previously showed that Dll4 down-regulates vascular endothelial growth factor (VEGF) rece...
Tissue migration is a collective behavior that plays a key role in the formation of many organ systems. Although tissue movements are guided by extrinsic cues, in many contexts, their receptors need to be active only at the leading edge to ensure morphogenesis. This has led to the prevalent view that extrinsic signals exert their influence by controlling a small number of leader cells. The zebr...
Chemokines and chemokine receptors have been posited to have important roles in several common malignancies, including breast and lung cancer. Here, we demonstrate that CXCR7 (RDC1, CCX-CKR2), recently deorphanized as a chemokine receptor that binds chemokines CXCL11 and CXCL12, can regulate these two common malignancies. Using a combination of overexpression and RNA interference, we establish ...
BACKGROUND CXCR7 (RDC1), the recently discovered second receptor for CXCL12, is phylogenetically closely related to chemokine receptors, but fails to couple to G-proteins and to induce typical chemokine receptor mediated cellular responses. The function of CXCR7 is controversial. Some studies suggest a signaling activity in mammalian cells and zebrafish embryos, while others indicate a decoy ac...
