Role of ANO1‐Expressing PDGFRα+ Smooth Muscle Cells in Generating Spontaneous Phasic Contractions of the Rodent Epididymis

open access: yesAndrology, EarlyView.
ABSTRACT Background Spontaneous phasic contractions (SPCs) in the epididymal duct play an important role in transport and maturation of sperm. In proximal cauda of the rat epididymis, platelet‐derived growth factor receptor α (PDGFRα)‐positive smooth muscle cells (SMCs) generate ANO1 Ca2+‐activated chloride channels (CaCCs)‐dependent spontaneous ...

6‐Nitrodopamine as a Novel Mediator of Prostatic Smooth Muscle Function in Mouse and Human

open access: yesAndrology, EarlyView.
ABSTRACT Background Epithelium‐derived catecholamines contribute to local regulation of genitourinary smooth muscle function, but the role of the endogenous 6‐nitrodopamine (6‐ND) in the prostate remains unknown. Objectives To determine whether 6‐ND is produced by mouse and human prostate and its role in smooth muscle regulation.

PDE4D and PDE3B orchestrate distinct cAMP microdomains in 3T3‐L1 adipocytes

open access: yesBritish Journal of Pharmacology, EarlyView.
Basal conditions: •Ins/PDE3B lowers cytoplasmic cAMP (cyt‐cAMP) without affecting plasma membrane cAMP (pm‐cAMP). •Insulin decreases lipid droplet cAMP (LD‐cAMP) independent of PDE3B. •FGF1/PDE4D modestly reduces both cyt‐ and pm‐cAMP, while PDE4D alone can modulate LD‐cAMP. ISO stimulation: •Ins/PDE3B has minimal impact on cyt‐cAMP.

Metabolomic profiling of pheochromocytomas in dogs: Catecholamine phenotype and tricarboxylic acid cycle metabolites

open access: yesJournal of Veterinary Internal Medicine
Background In humans with pheochromocytomas (PCCs), targeted metabolomics is used to determine the catecholamine phenotype or to uncover underlying pathogenic variants in tricarboxylic acid (TCA) cycle genes such as succinate dehydrogenase subunits (SDHx)

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

Direct evidence implicating the asymmetrical dimethylarginine (ADMA)‐dimethylarginine dimethylaminohydrolase 1 (DDAH1) pathway in cerebrovascular dysfunction and stroke pathogenesis in mice

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Asymmetrical dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide synthase (NOS), whereas dimethylaminohydrolase 1 (DDAH1) is primarily responsible for its metabolism. However, the roles of DDAH1 in cerebrovascular regulation are poorly understood. Furthermore, despite evidence that elevated ADMA levels are

Phloroglucinol inhibits human ureteral contractions via activation of cAMP‐PKA pathway

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Phloroglucinol is used to treat renal colic, especially when non‐steroidal anti‐inflammatory drugs are contraindicated. This study aimed to clarify its mechanism by examining effects on human ureteral contractility and underlying signalling pathways. Experimental Approach Urinary levels of neurokinin A (NKA), substance P
