Angiotensin II (AngII) has been strongly implicated in hypertension and its complications. Evidence suggests the mechanisms by which AngII elevates blood pressure and enhances cardiovascular remodeling and damage may be distinct. However, the signal transduction cascade by which AngII specifically initiates cardiovascular remodeling, such as hypertrophy and fibrosis, remains insufficiently unde...

Many guidance receptors are proteolytically cleaved by membrane-associated metalloproteases of the ADAM family, leading to the shedding of their ectodomains. Ectodomain shedding is crucial for receptor signaling and function, but how this process is controlled in neurons remains poorly understood. Here, we show that the transmembrane protein Lrig2 negatively regulates ADAM-mediated guidance rec...

Epithelial-mesenchymal crosstalk is essential for tissue morphogenesis, but incompletely understood. Postnatal mammary gland development requires epidermal growth factor receptor (EGFR) and its ligand amphiregulin (AREG), which generally must be cleaved from its transmembrane form in order to function. As the transmembrane metalloproteinase ADAM17 can process AREG in culture and Adam17(-/-) mic...

A MAJORITY of growth factors, including members of the epidermal growth factors (EGF) family, are synthesized as proproteins, requiring cleavage for the mediation of some of their functions. This pro-protein cleavage of the EGF family members is performed by disintegrin and metalloprotease (ADAM) family members and matrix metalloproteinases (MMPs) and is tightly regulated by various factors (9)...

Both ADAM17, the secretase responsible for the shedding of ectodomains of numerous membrane proteins including TNF and its receptors, as well as nitric oxide synthesized by inducible nitric oxide synthase play regulatory roles in inflammation and tumor progression. We analyzed the effect of endogenous and exogenous nitric oxide on the expression and activity of ADAM17 in murine endothelial cell...

wish to make a correction. The construct TTKK in Figure 4 of the article should be labeled TTTK, since it encodes a chimeric protein with the extracellular domain and transmembrane domain of ADAM17 (TACE, T) fused to the cytoplasmic domain of ADAM10 (KUZ, K). This correction applies to all results obtained with the TTKK construct in Figure 4B, Figure 6D, and Supplemental Figure 2. Therefore, no...

Tumour necrosis factor-α (TNF-α) converting enzyme (TACE), also termed a disintegrin and metalloprotease 17 (ADAM17), is involved in multiple cell signalling pathways. Through the secretion of epidermal growth factor receptor (EGFR) ligands, ADAM17 can activate the EGFR and is involved in various downstream signalling pathways. The present study aimed to investigate whether ADAM17‑induced EGFR ...

Epithelial regeneration is a key process for the recovery from ulcerative colitis (UC). Here we demonstrate that a disintegrin and metalloproteinase-17 (ADAM17), a main sheddase for tumor necrosis factor (TNF)-α, is essential for defensive epithelial properties against UC by promoting epithelial cell growth and goblet cell differentiation in mouse and human. Mice with systemic deletion of Adam1...

BACKGROUND Expression of the Sp1 transcription factor is induced by hypoxia, and the ADAM17 promoter contains predicted Sp1 binding sites. ADAM17 contributes to hypoxic-induce invasiveness of glioma. In this study, we investigated whether Sp1 transcription factor induces ADAM17 and/or contributes to tumor cell invasiveness in hypoxia. METHODS Employing RT-PCR and Western blot, we examined the...
