The extracellular signals induced by vascular endothelial growth factor (VEGF) are implicated in choroidal neovascularization (CNV) and thus, are associated with vision-limiting complications in the human retina. Vandetanib is an oral anticancer drug that selectively inhibits the activities of VEGF receptor and epidermal growth factor receptor tyrosine kinase; however, the effects of vandetanib...
Cross-talk between G protein-coupled receptor (GPCR) and epidermal growth factor receptor (EGFR) signaling systems is widely established in a variety of normal and transformed cell types. Here, we demonstrate that the EGFR transactivation signal requires metalloproteinase cleavage of epidermal growth factor-like growth factor precursors in fibroblasts, ACHN kidney, and TccSup bladder carcinoma ...
Semaphorin 4D (Sema4D) is a transmembrane protein that supports contact-dependent amplification of platelet activation by collagen before being gradually cleaved by the metalloprotease ADAM17, as we have previously shown. Cleavage releases a soluble 120-kDa exodomain fragment for which receptors exist on platelets and endothelial cells. Here we have examined the mechanism that regulates Sema4D ...
Background—Angiotensin II (Ang II) promotes growth of vascular smooth muscle cells (VSMCs) via epidermal growth factor (EGF) receptor (EGFR) transactivation mediated through a metalloprotease-dependent shedding of heparinbinding EGF-like growth factor (HB-EGF). However, the identity of the metalloprotease responsible for this process remains unknown. Methods and Results—To identify the metallop...

A disintegrin and metalloproteinase (ADAM) is a family of enzymes involved in ectodomain shedding of various membrane proteins. However, the molecular mechanism underlying substrate recognition by ADAMs remains unknown. In this study, we successfully captured and analyzed cell surface transient assemblies between the transmembrane amphiregulin precursor (proAREG) and ADAM17 during an early shed...
OBJECTIVE Atherosclerosis is accelerated in subjects with type 2 diabetes by unknown mechanisms. We identified tissue inhibitor of metalloproteinase 3 (TIMP3), the endogenous inhibitor of A disintegrin and metalloprotease domain 17 (ADAM17) and other matrix metalloproteinases (MMPs), as a gene modifier for insulin resistance and vascular inflammation in mice. We tested its association with athe...
A disintegrin and metalloproteases (ADAMs) have been implicated in many processes controlling organismic development and integrity. Important substrates of ADAM proteases include growth factors, cytokines and their receptors and adhesion proteins. The inducible but irreversible cleavage of their substrates alters cell-cell communication and signaling. The crucial role of ADAM proteases (e.g. AD...
Chemokines are the inflammatory mediators that modulate liver fibrosis, a common feature of chronic inflammatory liver diseases. CX3CL1/fractalkine is a membrane-associated chemokine that requires step processing for chemotactic activity and has been recently implicated in liver disease. Here, we investigated the potential shedding activities involved in the release of the soluble chemotactic p...
ADAM17 is a disintegrin and metalloproteinase capable of cleaving the ectodomains diverse variety molecules including TNF-?, TGF-?, L-selectin, ACE2. We have previously demonstrated that renal upregulated in diabetic mice. The role endothelial (eAdam17) proximal tubular (tAdam17) Adam17 deletion histology, modulation renin angiotensin system (RAS), inflammation, fibrosis was studied mouse model...
