Mutations of the adenylyl cyclase gene that block RAS function in Saccharomyces cerevisiae

open access: yes, 1990
The interaction between RAS proteins and adenylyl cyclase was studied by using dominant interfering mutations of adenylyl cyclase from the yeast Saccharomyces cerevisiae. RAS proteins activate adenylyl cyclase in this organism.

Characterization of Plasmodium falciparum adenylyl cyclase-β and its role in erythrocytic stage parasites. [PDF]

open access: yesPLoS ONE, 2012
The most severe form of human malaria is caused by the parasite Plasmodium falciparum. The second messenger cAMP has been shown to be important for the parasite's ability to infect the host's liver, but its role during parasite growth inside erythrocytes,

An intracellular recombinant single‐chain variable antibody fragment as a new class of phosphodiesterase type 5 inhibitors

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a ubiquitous second messenger involved in human (patho‐)physiology. Phosphodiesterase 5 (PDE5) is a major cGMP hydrolyzing enzyme in many cell types including vascular smooth muscle cells (VSMCs). Several highly selective PDE5 inhibitors are in clinical use. However, there are currently no

The adenylyl cyclase signaling system in normal and failing myocardium [PDF]

open access: yes, 2014
This bachelor thesis describes a signal pathway of adenylyl cyclase, which plays a key role in the modulation of heart rate and force of contraction.

The bZIP transcription factor Rca1p is a central regulator of a novel CO₂ sensing pathway in yeast.

open access: yesPLoS Pathogens, 2012
Like many organisms the fungal pathogen Candida albicans senses changes in the environmental CO(2) concentration. This response involves two major proteins: adenylyl cyclase and carbonic anhydrase (CA).

Cannabigerol reverses mechanical allodynia through α2A‐adrenergic modulation of thalamocortical signaling in chemotherapy‐induced neuropathy

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Chemotherapy‐induced peripheral neuropathy (CIPN) is a prevalent and treatment‐resistant side effect of platinum‐based chemotherapy, characterised by mechanical allodynia. Cannabigerol (CBG), a non‐psychoactive cannabinoid, has shown antinociceptive potential, but its site and mechanism of action remain unclear.

Atrial natriuretic peptide counteracts aldosterone secretion by preventing acute angiotensin II‐induced cAMP signalling

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Aldosterone plays a key role in blood pressure and volume regulation. Enhanced aldosterone secretion contributes to cardiovascular and renal diseases. Therefore, inhibitors of aldosterone receptors and synthase are essential drugs for the treatment of hypertension and heart failure.

Ca2+ inhibition of type III adenylyl cyclase in vivo

open access: yes, 1995
Type III adenylyl cyclase is stimulated by beta-adrenergic agonists and glucagon in vitro and in vivo, but not by Ca2+ and calmodulin. However, the enzyme is stimulated by Ca2+ and calmodulin in vitro when it is concomitantly activated by the guanyl ...

Alamandine/MrgD pathway modulates gut–bone marrow axis in ageing

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Ageing is associated with colon epithelial barrier disruption and up‐regulation of myelopoiesis in the bone marrow (BM). Alamandine (Ala) and MrgD are novel members of the renin angiotensin system (RAS). This study tested the hypothesis that Ala restores the colon epithelial barrier integrity in ageing via modulating gut–
