Iwata M, Silva Enciso J, Greenberg BH. Selective and specific regulation of ectodomain shedding of angiotensin-converting enzyme 2 by tumor necrosis factor -converting enzyme. Am J Physiol Cell Physiol 297: C1318–C1329, 2009. First published September 16, 2009; doi:10.1152/ajpcell.00036.2009.—Angiotensin-converting enzyme 2 (ACE2) is a newly identified regulator of the renin-angiotensin system....

Ectodomain shedding of cell surface membrane-anchoring proteins is an important process in a wide variety of physiological events(1, 2). Tumor necrosis factor alpha (TNF-alpha) converting enzyme (TACE) is the first discovered mammalian sheddase responsible for cleavage of several important surface proteins, including TNF-alpha, TNF p75 receptor, L-selectin, and transforming growth factor-a. Pho...

The ectodomains of numerous proteins are released from cells by proteolysis to yield soluble intercellular regulators. The responsible protease, tumor necrosis factor-á converting enzyme (TACE), has been identified only in the case when tumor necrosis factor-á (TNFá) is released. Analyses of cells lacking this metalloproteinase-disintegrin revealed an expanded role for TACE in the processing of...

BACKGROUND Transarterial chemoembolization (TACE) is recommended as the standard care for unresectable hepatocellular carcinoma (HCC) at Barcelona Clinic Liver Cancer (BCLC) stage A-B. However, the efficacy of TACE on large (≥ 10 cm) stage A-B HCC is far from satisfactory, and it is proposed that hepatic artery infusion chemotherapy (HAIC) might be a better first-line treatment of this disease....

TNF-alpha converting enzyme (TACE/ADAM17) is a transmembrane metalloprotease that plays a key role in the cleavage and mobilization of receptor ligands that are initially synthesized as membrane-tethered precursors. For many years, attention has focused on the role of TACE-dependent TNF-alpha cleavage in arthritis and, more recently, it has become apparent that TACE also plays an important role...

Transcatheter arterial chemoembolization (TACE) is known to be an effective palliative treatment in unresectable hepatocellular carcinoma (HCC). Although TACE can control tumour growth and palliate the patients, complications of TACE with significant morbidity are well known and adversely affect the outcome of patients. Necrotic tumor rupture is a serious complication of TACE and has a high mor...

BACKGROUND/AIMS The predictive role of contrast-enhanced ultrasonography (CEUS) before performing transarterial chemoembolization (TACE) has not been determined. We assessed the possible predictive factors of CEUS for the response to TACE. METHODS Seventeen patients with 18 hepatocellular carcinoma (HCC) underwent TACE. All of the tumors were studied with CEUS before TACE using a second-gener...

The treatment efficacy of unresectable hepatocellular carcinoma (HCC) is still not promising. This study aimed to compare the efficacy and safety of radiofrequency ablation (RFA) combined with transarterial chemoembolization (TACE) for unresectable HCC with a single treatment.Between June 2009 and June 2012, 132 patients who were diagnosed with unresectable HCC and accepted nonsurgical treatmen...

Targeted therapy is currently the standard treatment for advanced hepatocellular carcinoma (HCC), but an effective treatment after the discontinuation of sorafenib therapy remains uncertain. We aim to investigate the survival benefits of transcatheter arterial chemoembolization (TACE) after stopping sorafenib therapy. We retrospectively analyzed all patients with advanced HCC, who had received ...

Although transcatheter arterial chemoembolization (TACE) is considered to be an effective treatment for advanced hepatocellular carcinoma (HCC), it is difficult to achieve complete necrosis by TACE alone due to incomplete embolization and tumor angiogenesis. Recent studies have shown that tegafur/uracil (UFT) inhibits tumor angiogenesis in several cancer types. Therefore, this study was conduct...
