An antimicrobial protein of about 10 kD, called Ace-AMP1, was isolated from onion (Allium cepa L.) seeds. Based on the near-complete amino acid sequence of this protein, oligonucleotides were designed for polymerase chain reaction-based cloning of the corresponding cDNA. The mature protein is homologous to plant nonspecific lipid transfer proteins (nsLTPs), but it shares only 76% of the residue...

The effect of dexamethasone on angiotensin-converting enzyme (ACE) in primary culture of adult cardiac fibroblasts was analyzed in this study. ACE is central to cardiac remodeling in conditions such as myocardial infarction (MI). Some studies indicate that glucocorticoids are often increased post-MI, whereas other studies suggest that glucocorticoids stimulate ACE activity in various cell types...

Reducing excessive accumulation of amyloid-β (Aβ) in Alzheimer's disease (AD) is a key objective of most AD therapies, and inhibition of angiotensin-converting enzyme (ACE) may delay onset or progression of AD. The effects of an ACE-inhibitor (ACE-I) and an angiotensin II receptor blocker (ARB) on Aβ and tau pathology in a triple transgenic (3xTGAD) mouse model of AD were investigated. 9-10mont...

Clustering of diseases has been appreciated by health insurers and epidemiologists for some time. Co-morbidity suggests shared pathways of disease. It is by now well agreed that common diseases have a strong genetic component. Here we present evidence that the angiotensin I-converting enzyme (ACE) deletion/deletion (D/D) genotype is associated with a large number of common adult diseases, inclu...

AIM We investigated the expression of the renin-angiotensin system (RAS) by cancer stem cell (CSC) subpopulations we have identified in moderately differentiated lip squamous cell carcinoma (MDLSCC). METHOD Ten MDLSCC samples underwent 3,3-diaminobenzidine (DAB) and immunofluorescent immunohistochemical (IHC) staining for (pro)renin receptor (PRR), angiotensin-converting enzyme (ACE), angiote...

The benefit of the add-on angiotensin II receptor blocker candesartan to angiotensin-converting enzyme (ACE) inhibitors in inhibition of progression of nephropathy in hypertensive patient with nondiabetic renal disease compared with monotherapy with ACE inhibitors remains controversial. All patients were previously treated with ACE inhibitors. Urinary protein excretion of patients exceeded 1.0 ...

Mammalian angiotensin-converting enzyme (ACE; EC 3.4.15.1) is one of several proteins that exist in both membrane-bound and soluble forms as a result of a post-translational proteolytic processing event. For ACE we have previously identified a metalloprotease (secretase) responsible for this proteolytic cleavage. The effect of a range of structurally related zinc metalloprotease inhibitors on t...

The thermodynamic, kinetic, and structural properties of Ln3+ complexes with the bifunctional DO3A-ACE4? ligand its amide derivative DO3A-BACE4? (modelling case where binds to vector molecules) have been studied in order confirm usefulness corresponding Gd3+ as relaxation labels targeted MRI contrast agents. stability constants Mg2+ Ca2+ are lower than for DOTA4? DO3A3?, while Zn2+ Cu2+ similar...

The effect of corticosteroids on angiotensin converting enzyme was investigated in endothelial cell cultures and intact rat lung. Cultured endothelial cells from bovine aorta showed net production of angiotensin converting enzyme (ACE) over 2 d culture in serum-free medium. Dexamethasone (DM) increased cell ACE activity six- to sevenfold at 100 nM with a threshold effect at 0.3 nM. The effect o...
