Putative Nucleotide-Based Second Messengers in the Archaeal Model Organisms Haloferax volcanii and Sulfolobus acidocaldarius

Frontiers in Microbiology, 2021
Research on nucleotide-based second messengers began in 1956 with the discovery of cyclic adenosine monophosphate (3′,5′-cAMP) by Earl Wilbur Sutherland and his co-workers.

A non-canonical, interferon-independent signaling activity of cGAMP triggers DNA damage response signaling

Nature Communications, 2021
Cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) is normally induced by innate immunity sensing for protection from pathogens. Here the authors show that cGAMP is also upstream of DNA damage signaling by activating ATM-CHK2-mediated repair ...

Development of a red fluorescent protein-based cGMP indicator applicable for live-cell imaging

Communications Biology, 2022
A red fluorescent protein-based indicator of cyclic guanosine 3′, 5′-monophosphate (cGMP) allows for multi-colour imaging and optogenetic applications while monitoring cGMP activity in cells.

Vericiguat: A New Hope for Heart Failure Patients

Cardiovascular Therapeutics, 2022
Heart failure with reduced ejection fraction (HFrEF) is the inability of the heart to adequately contract or eject blood. This heart is unable to produce adequate cardiac output to perfuse vital tissues.

The role of Phosphodiesterase-1 and its natural product inhibitors in Alzheimer’s disease: A review

Frontiers in Pharmacology, 2022
Phosphodiesterase-1 (PDE1) is a versatile enzyme that has surprisingly received considerable attention as a possible therapeutic target in Alzheimer’s disease (AD) because it maintains the homeostasis of 3ʹ,5ʹ-cyclic adenosine monophosphate (cAMP) and 3ʹ,

Effect of cyclic 
guanosine‐monophosphate on porcine retinal vasomotion [PDF]

Acta Ophthalmologica Scandinavica, 2006
Abstract.Purpose:  Vasomotion refers to periodic oscillations in vascular tone that ensure the intermittent supply of blood to adjacent microvascular units. Previous evidence from vessels outside the eye suggests that cyclic guanosine‐monophosphate (cGMP) is involved in the regulation of vasomotion, but it is unknown whether this compound has an ...

Imaging of PDE2- and PDE3-Mediated cGMP-to-cAMP Cross-Talk in Cardiomyocytes

Journal of Cardiovascular Development and Disease, 2018
Cyclic nucleotides 3′,5′-cyclic adenosine monophosphate (cAMP) and 3′,5′-cyclic guanosine monophosphate (cGMP) are important second messengers that regulate cardiovascular function and disease by acting in discrete subcellular microdomains.

Cyclic nucleotide signalling in malaria parasites [PDF]

Open Biology, 2017
The cyclic nucleotides 3′, 5′-cyclic adenosine monophosphate (cAMP) and 3′, 5′-cyclic guanosine monophosphate (cGMP) are intracellular messengers found in most animal cell types.
