The atrial natriuretic peptide (ANP)-C receptor is generally believed to clear ANP; however, the ANP-C receptor may serve to reduce cAMP by inhibiting adenylate cyclase. ANP decreases endothelial permeability in coronary endothelial cell monolayers. We tested the hypothesis that part of this effect might be mediated by the ANP-C receptor. We used an endothelial cell monolayer from rat coronary ...
Three atrial natriuretic peptide (ANP) receptors, ANP(A), ANP(B), and ANP(C), have been identified in the heart, suggesting that natriuretic peptides may have direct effects on cardiac function. To characterize the possible role of atrial natriuretic peptide (ANP) in the regulation of its own secretion, we studied here the effects of ANP (greater affinity for ANP(A) than for ANP(B) receptors) a...
Acute coronary artery occlusion triggers the release of atrial natriuretic peptide (ANP) from the heart. ANP affects vasodilation, natriuresis, and inflammation, but the integrated biological effects of ANP on myocardial infarction are unknown. To elucidate these effects, the left anterior coronary artery was ligated in anesthetized, ANP-deficient (ANP(-/-)) and congenic wild-type (ANP(+/+)) mi...
چکیده درآمد مالیاتی یکی از مهمترین راههای تأمین منابع دولت است. اما تحقق این درآمد با وجود فرار مالیاتی دچار اختلال میشود و از پیامدهای فرار مالیاتی، کاهش درآمد مالیاتی و در نتیجه کسری بودجه دولت است. شکلگیری گسترش پدیده فرار مالیاتی خود معلول عواملی است. جرایم مالیاتی به عنوان یکی از ابزارها، از سوی قانونگذار برای برخورد با متخلفان مالیاتی وضع شده است. هدف از این تحقیق بررسی جایگاه جرایم ما...

Atrial natriuretic peptide (ANP) released from enterochromaffin cells helps regulate antral somatostatin secretion, but the mechanisms regulating ANP secretion are not known. We superfused rat antral segments with selective neural agonists/antagonists to identify the neural pathways regulating ANP secretion. The nicotinic agonist 1,1-dimethyl-4-phenylpiperazinium (DMPP) stimulated ANP secretion...
Dilated cardiomyopathy is a frequent cause of heart failure and death. Atrial natriuretic peptide (ANP) is a biomarker of dilated cardiomyopathy, but there is controversy whether ANP modulates the development of heart failure. Therefore, we examined whether ANP affects heart failure, cardiac remodeling, function, and survival in a well-characterized, transgenic model of dilated cardiomyopathy. ...
Background: Atrial natriuretic peptide (ANP) and B-type natriuretic peptide (BNP) are cardiac peptide hormones with pivotal roles in maintaining cardiovascular homeostasis. BNP and its precursor fragment are accepted as gold standard markers for heart failure (HF). Human ANP is present in the atria of the heart and plasma as 3 endogenous molecular forms designated α-ANP, β-ANP, and proANP. A pr...
Atrial natriuretic peptide (ANP) receptors from A10 cultured vascular smooth muscle cells (VSMC) and rat olfactory bulbs have been solubilized and then pharmacologically and biochemically compared. The dissociation constant for 125I-ANP(99-126) was 12.7 pM for the VSMC-derived receptor and 164 pM for the olfactory receptor. Competition binding between 125I-ANP(99-126) and several unlabeled ANP ...
Binding sites for 125I-atrial natriuretic peptide (ANP)2 in rat olfactory bulb membranes have been studied using pharmacological and biochemical methods. Various unlabeled ANP-related peptides were tested for the ability to inhibit the binding of the radioligand in membrane binding assays. ANP(92-126) and ANP(99-126) were the most potent inhibitors tested, both exhibiting an IC50 value of 0.40 ...
