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

British 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

Distinct Spatiotemporal Distribution of Bacterial Toxin-Produced Cellular cAMP Differentially Inhibits Opsonophagocytic Signaling

Toxins, 2019
Myeloid phagocytes have evolved to rapidly recognize invading pathogens and clear them through opsonophagocytic killing. The adenylate cyclase toxin (CyaA) of Bordetella pertussis and the edema toxin (ET) of Bacillus anthracis are both calmodulin ...

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

British 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.

No evidence for oncogenic mutations in guanine nucleotide-binding proteins of human adrenocortical neoplasms [PDF]

, 1933
G-Proteins are membrane-bound heterotrimeric polypeptides that couple receptor signals to second messenger systems such as cAMP. Recently, point mutations at 2 codons of the highly preserved alpha-chain of Gs, the adenyl cyclase-stimulating G-protein ...

Label-free fluorescent real-time monitoring of adenylyl cyclase

, 2015
In cellular signaling, adenylyl cyclase plays a key role in the hydrolysis of ATP to cyclic AMP and pyrophosphate. Using a synthetic fluorescent chemosensor (PyDPA) which binds strongly to the pyrophosphate group, we have developed a label-free ...

Dual pharmacological targeting of coactivator‐associated arginine methyltransferase 1 (CARM1) and salt inducible kinase (SIK) drives ketogenesis in both hepatocytes and mice

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Ketone bodies are liver‐derived circulating energy metabolites that positively impact most hallmarks of ageing. Ketone bodies increase during calorie restriction and fasting, two of the more widely perceived methods to increase health span.

Enhancement of Sphingosine 1-Phosphate-Induced Phospholipase C Activation During G0-G1 Transition in Rat Hepatocytes

Journal of Pharmacological Sciences, 2004
We previously reported that sphingosine 1-phosphate (S1P) induces inhibition of adenylyl cyclase and activation of phospholipase C via independent G protein-coupled receptors in adult rat hepatocytes.

Adenylyl Cyclases in Mycobacteria [PDF]

Journal of Life Science, 2011
Adenylyl cyclase (AC) catalyzes the formation of cyclic AMP (cAMP) from ATP. The cAMP produced by AC serves as a secondary messenger in a variety of signal transduction pathways, and controls various cellular functions in many organisms. ACs can be grouped into six classes based on their primary amino acid sequences. Eukaryotes and mycobacteria contain

Cannabinoid and adenosine A2A receptor crosstalk regulates postnatal and adult hippocampal neurogenesis

British Journal of Pharmacology, EarlyView.
Background and purpose Adult neurogenesis is a tightly regulated process affected by both cannabinoid receptors (CB1 and CB2) and adenosine 2A (A2A) receptors, both of which modulate neural progenitor cell activity. While emerging evidence suggests an interaction between these neuromodulatory systems, the extent and mechanism of their interplay in ...
