ADAM17/TACE might be an important therapeutic target. The blocking of ADAM17/TACE expression and/or the evaluation and development of specific TACE inhibitors might have therapeutic potential even in later stages of cancer. Furthermore, ADAM17/TACE might be useful as a diagnostic marker of pancreatic cancer to distinguish between PDAC and chronic pancreatitis. Aberrant ADAM17/TACE expression might be a diagnostic and therapeutic target in human pancreatic ductal adenocarcinoma

in order to explore the role of TACE and NF-kappa B in hyperoxia-induced brain-ischemic tolerance, rodents are exposed to 95% inspired hyperoxia 4 h/day for six consecutive days or for 24 continous hours (prolonged hyperoxia). 24 h after the treatment. TACE, serum TNF-alpha and phosphor-kappaBalpha expression is up-regulated. Brain ischemic tolerance, inspired hyperoxia and prolonged hyperoxia may partly exert their effects via triggering TACE/TNF-alpha /NF-kappaB

in this study the relationship between long-term alcohol consumption and the concentration of TACE in peripheral blood mononuclear cells and its substrate- soluble TNF-alpha receptor type 1 in plasma in psoriasis patients is analysed. The study is conducted among 44 patients (aged 30-59 years) with early-onset, plaque-type psoriasis. 38 patients (aged 29-61 years) with other than psoriasis chronic dermatologic disorders are controls. The data on alcohol consumption during previous 10 years are obtained with a structured questionnaire. The severity of the disease is assessed using Psoriasis Area and Severity Index (PASI), and concentrations of TACE in peripheral blood mononuclear cells lysate and soluble TNF-alpha receptor type 1 in plasma is assessed with a quantitative sandwich enzyme immunoassay technique. The alcohol abuse contributes to the increase of TACE expression in blood mononuclear cells and also to the elevated plasma soluble TNF-alpha receptor type 1 concentration in psoriasis patients

the relationship between ADAM17 and TNF polymorphisms, circulating levels of shed ADAM17 substrates, and cardiovascular risk in a prospective cohort of coronary artery disease patients is investigated. Five tag single-nucleotide polymorphisms (SNPs) of the ADAM17 gene as well as four previously described TNF SNPs are genotyped in the Atherogene Study composed of 1400 coronary artery disease patients among which 136 died from a cardiovascular cause. Soluble TNF, soluble TNF receptor 1, and soluble TNF receptor 2 concentrations are all significantly elevated in patients with future cardiovascular death, independently of other clinical/biological variables. The ADAM17-154A allele is found associated with a 14% increase of soluble TNF levels as compared to the -154C allele. Individuals carrying the 747Leu allele display a borderline increased risk of future cardiovascular death

1,25-dihydroxyvitamin D inhibition of TACE is a potential common mechanism underlying the efficacy of therapy with 1,25-dihydroxyvitamin D or its analogs to improve outcomes in chronic kidney disease. 1,25-dihydroxyvitamin D prevents/moderates not only the onset and progression of parathyroid TACE/TGFalpha-driven secondary hyperparathyroidism, but renal TACE/TGFalpha-driven fibrotic and inflammatory lesions to the renal parenchyma, and TACE/TNFalpha-driven systemic inflammation

anti-Ro/SSA autoantibodies determine TACE pro-domain shedding suggesting that TACE activity is necessary for the release of TNF-alpha observed in anti-Ro/SSA autoantibody-stimulated cells. Adalimumab appears to be significantly more efficacious than Etanercept in preventing TACE activation caused by anti-Ro/SSA autoantibodies. Regulation of TACE may participate in the pathogenic role of autoantibodies and the modulation of TACE expression by TNF-alpha antagonists might contribute to the beneficial effect of these drugs in inflammatory and autoimmune diseases

during acute H pylori infection, CagL dissociates ADAM17 from the integrin alpha(5)beta1 and activates ADAM17-dependent, nuclear factor-kappaB-mediated repression of HKalpha, i.e. gastric H, K-adenosine triphosphatase alpha-subunit. This might contribute to transient hypochlorhydria in patients with H pylori infection

expression of ADAM-17 is significantly increased in gallbladder carcinoma with high histological grade and pT stage compared with low histological grade and pT stage tumors and is not associated with patients gender, age, histological type, and resection margin involvement. Patients with high expression of ADAM-17 have a significantly shorter overall survival compared with those with low expression. The prognostic impact of ADAM-17 is independent of conventional prognostic factors for gallbladder carcinoma

metalloproteases ADAM-9, ADAM-15, and ADAM-17 are upregulated in advanced human atherosclerotic lesions in samples from carotid, aortic, and femoral territories compared to samples from internal thoracic artery free of atherosclerotic plaques. The enzymes are in the catalytically active form. ADAM-9, ADAM-15, and ADAM-17-expressing cells colocalize with CD68-positive cells of monocytic origin in the atherosclerotic plaques. Colocalization is demonstrated in all vascular territories

study on the association of ADAM-17 single nucleotide polymorphisms with insulin-resistance phenotypes and obesity risk. G allele carriers at the ADAM17_m1254A > G polymorphism exhibit significantly higher risk of obesity, are shorter, have higher insulin, and lower HDL-C concentrations than AA subjects. For the ADAM17_i33708A > G single nucleotide polymorphism, homozygotes for the A allele display higher risk of obesity, are heavier, have higher body-mass-index and higher waist measurements than GG subjects. There is a significant gene-diet interaction, in which the deleterious association of the i33708A allele with obesity is observed in subjects with low intakes from n-6 polyunsaturated fatty acids, whereas no differences in obesity risk are seen among subjects with high n-6 polyunsaturated fatty acid intake

treatment of mice in a lipopolysaccharide-induced endotoxemia model group with recombinant TACE prodomain protein prior to the injection of lipopolysaccharide. The recombinant prodomain protein decreases the release of the secreted TNF-alpha, which mediates the accumulation of TNF-alpha on the surface of macrophage cells. The recombinant protein can decrease the inflammatory response in internal organs of endotoxaemia mice

ADAM17 expression levels are correlated with the invasive ability of androgen-independent prostate cancer cell lines. ADAM17 is overexpressed in cells showing high invasion characteristics, activation of the EGFR-MEK-ERK pathway, up-regulation of MMP-2, MMP-9, and an increased TGF-alpha release into the supernatant. AG1478, PD98059 and antibody against TGF-alpha deactivating the EGFR-MEK-ERK signaling pathway, abolish up-regulation of MMP-2, MMP-9 and prevent cell invasion. Cells with knock-down of ADAM17 by siRNA exhibit low invasive ability, deactivated EGFR-MEK-ERK signaling pathway, reduced TGF-alpha release and down-regulation of MMP-2, MMP-9
medicine
ectopic over-expression of ADAM17 results in increased cell proliferation. ADAM17 promotes G1 to S phase transition concomitantly with upregulation of cyclin E, CDK2 and downregulation of p21 and p27 proteins. ADAM17 over-expression cells show more TGF-alpha released to the supernatant and activate the EGFR/PI3K/AKT pathway. Silencing ADAM17 leads to the opposite effect. Both siRNAs knockdown of ADAM17 and blocking the EGFR/PI3K/AKT pathway cause downregulation of cyclin E,CDK2,and upregulation of p21 and p27 in prostate cancer cells
