Effect of 8-bromo-cyclic guanosine monophosphate (cGMP) on coronary artery constriction in isolated rabbit hearts.
The vasodilator 8-bromo-guanosine 3':5'-monophosphate (8-bromo-cGMP) effectively counteracts vasopressin-induced coronary artery constriction in a supported perfused working rabbit heart. In this preparation, the coronary arteries remain in contact with the beating heart. The obtuse marginal artery and portions of the left anterior descending coronary artery were deprived of endothelium. Perfus...
متن کامل8-Bromo-3',5'-adenosine monophosphate stimulates the endocrine activity of human cytotrophoblasts in culture.
Cytotrophoblasts, purified from human term placentae, were cultured in the absence or presence of 8-bromo-cAMP or 8-bromo-cGMP. 8-Bromo-cAMP provoked a dose-dependent increase in the secretion of hCG and progesterone within 24 h. After 48 h, hCG secretion increased by more than 200-fold, and progesterone secretion increased nearly 5-fold. 8-Bromo-cGMP had no effect on hCG secretion. In culture ...
متن کاملGuanosine 3',5'-cyclic monophosphate (cGMP)/cGMP-dependent protein kinase induce interleukin-6 transcription in osteoblasts.
Natriuretic peptides and nitric oxide (NO) activate the cGMP/cGMP-dependent protein kinase (PKG) signaling pathway and play an important role in bone development and adult bone homeostasis. The cytokine IL-6 regulates bone turnover and osteoclast and osteoblast differentiation. We found that C-type natriuretic peptide and the NO donor Deta-NONOate induced IL-6 mRNA expression in primary human o...
متن کاملEffect of 8-bromo-cyclic guanosine monophosphate on intracellular pH and calcium in vascular smooth muscle.
Endothelium-dependent vasodilators, nitrates, and atrial natriuretic factor relax blood vessels by increasing vascular cyclic guanosine monophosphate (cGMP). The mechanisms by which cGMP relaxes vascular smooth muscle (VSM) are not known. Since contraction of VSM is associated with increased intracellular calcium and pH, we hypothesized that cGMP may decrease vascular tone by lowering ionized, ...
متن کاملUrinary excretion of cyclic adenosine 3',5'-monophosphate and cyclic guanosine 3',5'-monophosphate in malignancy.
The urinary excretion of cyclic adenosine 3',5'-monophosphate (cAMP), corrected for urinary creatinine, was determined in 177 patients with primary or metastatic tumours and in 149 normal subjects. In 26 patients with malignancy and in 10 control subjects the excretion of cyclic guanosine 3',5'-monophosphate (cGMP) was also evaluated. The urinary cAMP/Cr ratio in human neoplasms of epithelial o...
