Biphasic roles for soluble guanylyl cyclase (sGC) in platelet activation.
Nitric oxide (NO) stimulates cGMP synthesis by activating its intracellular receptor, soluble guanylyl cyclase (sGC). It is a currently prevailing concept that No and cGMP inhibits platelet function. However, the data supporting the inhibitory role of NO/sGC/cGMP in platelets have been obtained either in vitro or using whole body gene deletion that affects vessel wall function. Here we have gen...
متن کاملStimulation of Soluble Guanylyl Cyclase (sGC) Inhibits Mesangial Cell Proliferation and Matrix Accumulation in Experimental Glomerulonephritis
Background: To date no specific treatment is established in mesangial proliferative glomerulonephritis in man. Specific stimulation of soluble guanylyl cyclase (sGC), an enzyme catalyzing the synthesis of cyclic GMP from GTP, can be achieved by the novel pyrazolopyridine derivative Bay 41-2272. In this study, we investigated the effects of sGC stimulation in experimental mesangial proliferative...

متن کاملA constitutively activated mutant of human soluble guanylyl cyclase (sGC): implication for the mechanism of sGC activation.
Heterodimeric alphabeta soluble guanylyl cyclase (sGC) is a recognized receptor for nitric oxide (NO) and mediates many of its physiological functions. Although it has been clear that the heme moiety coordinated by His-105 of the beta subunit is crucial for mediating the activation of the enzyme by NO, it is not understood whether the heme moiety plays any role in the function of the enzyme in ...
متن کاملNucleotidyl cyclase activity of soluble guanylyl cyclase in intact cells.
Soluble guanylyl cyclase (sGC) is activated by nitric oxide (NO) and generates the second messenger cyclic GMP (cGMP). Recently, purified sGC α1β1 has been shown to additionally generate the cyclic pyrimidine nucleotides cCMP and cUMP. However, since cyclic pyrimidine nucleotide formation occurred only the presence of Mn(2+) but not Mg(2+), the physiological relevance of these in vitro findings...
