Regulation of adiponectin secretion by endothelin-1.
Adiponectin is an adipocyte-derived hormone best known for its insulin-sensitizing ability. The expression and circulating concentration of adiponectin are decreased in type 2 diabetics and increase following treatment with thiazolidinediones. Endothelin-1 (ET-1) is a potent vasoconstrictor peptide whose levels are elevated in numerous disease states, including obesity and diabetes. ET-1 has pr...
متن کاملHeredity of endothelin secretion: human twin studies reveal the influence of polymorphism at the chromogranin A locus, a novel determinant of endothelial function.
BACKGROUND Endothelial dysfunction predisposes to vascular injury in association with hypertension. Endothelin (ET-1) is a potent vasoactive peptide that is synthesized and released by the vascular endothelium and is a marker of endothelial function. Chromogranin A (CHGA) regulates the storage and release of catecholamines and may have direct actions on the microvasculature. CHGA, a candidate g...
متن کاملEndothelin-stimulated secretion of natriuretic peptides by rat atrial myocytes is mediated by endothelin A receptors.
Endothelin (ET), a potent vasoconstrictor peptide, is known to enhance the secretion of atrial natriuretic factor (ANF) by the heart. In the present study, we investigated the potency of ET isopeptides to stimulate ANF and brain natriuretic peptide (BNP) secretion in primary cultures of neonatal atrial myocytes, and we characterized the receptor mediating these effects. All ET isopeptides cause...
متن کاملEndothelin receptor subtypes and stimulation of aldosterone secretion.
Endothelins (ETs) are 21-amino acid peptides with two disulfide bonds that have powerful vasoactive properties. We have previously shown the presence of a specific, high-affinity, saturable receptor for porcine or human endothelin (ET-1) in cultured calf zona glomerulosa cells. ET-1 was a stimulator of aldosterone secretion although not as powerful as angiotensin II. Incubations of cultured cal...
متن کاملRole of endothelin receptor subtypes in volume-stimulated ANF secretion.
The role of endothelin (ET) receptors was tested in volume-stimulated atrial natriuretic factor (ANF) secretion in conscious rats. Mean ANF responses to slow infusions (3 x 3.3 ml/8 min) were dose dependently reduced (P < 0.05) by bosentan (nonselective ET-receptor antagonist) from 64.1 +/- 18.1 (SE) pg/ml (control) to 52.6 +/- 16.1 (0.033 mg bosentan/rat), 16.1 +/- 7.6 (0. 33 mg/rat), and 11.6...
