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

Differential segment‐specific signalling pathways for guanylate cyclase C‐activated anion secretion in murine ileocolon

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Guanylate cyclase‐C (GC‐C) is the receptor for endogenous (uro)guanylin peptides, bacterial toxins and pharmacological analogues. Receptor activation leads to intestinal fluid loss, but also activates an antiproliferative pathway and is a promising target in colorectal cancer therapy.

Krisanaklan Reduces Intestinal Anion and Fluid Secretion Through Inhibition of Na+/K+‐ATPase and K+ Channel Activity

Annals of the New York Academy of Sciences, EarlyView.
Krisanaklan reduces CFTR‐dependent intestinal chloride and fluid secretion by inhibiting the Na+,K+‐ATPase and K+ channels in epithelial cells. Consequently, this natural, plant‐derived product may limit secretory diarrhea caused by a diverse array of microbial pathogens. However, by dissipating the transmembrane Na+ gradient, Krisanaklan also inhibits

Sodium thiosulfate treatment rescues hyperglycaemia‐induced pronephros damage in zebrafish by upregulating nitric oxide signalling

The Journal of Physiology, EarlyView.
Abstract figure legend Sodium thiosulfate (STS) rescues the pronephros phenotype of pdx1 morphants through compensatory upregulation of nitric oxide (NO) metabolism. Zebrafish larvae injected with a control morpholino show the typical pronephros structure at 48 h post‐fertilization (hpf) with and without STS treatment.

Computational modelling of cardiac fibroblast signalling reveals a key role for Ca2+ in driving atrial fibrillation‐associated fibrosis

The Journal of Physiology, EarlyView.
Abstract figure legend A pre‐existing fibroblast signalling model was enhanced by integrating atrial‐specific components and reactions linked to atrial fibrosis and atrial fibrillation (AF). The analysis highlights the central role of Ca2⁺ signalling in driving profibrotic responses to AF‐relevant stimuli, angiotensin‐II and transforming growth factor ...

Single‐cell analysis reveals neuroprotective histone deacetylase inhibitor pathways

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Alzheimer's disease (AD) involves β‐amyloid (Aβ) accumulation, tau pathology, and neuroinflammation, driving cognitive decline. Despite extensive research, disease‐modifying therapies remain elusive. We integrated single‐cell RNA sequencing (scRNA‐seq), spatial transcriptomics, and in vitro validation to identify repurposable ...

Pharmacokinetics, pharmacodynamics, and safety interaction study of tunodafil hydrochloride and alcohol: A randomized, blinded, placebo‐controlled, three‐cycle crossover study in Chinese healthy men

Andrology, Volume 14, Issue 2, Page 466-479, February 2026.
Abstract Objectives This study aimed to evaluate the pharmacodynamic effects of administering tunodafil hydrochloride with alcohol on blood pressure and heart rate in healthy Chinese males, and to investigate the mutual pharmacokinetic interactions and safety of the combination.

Assessment of exercise tolerance using cardiopulmonary exercise test in patients with chronic obstructive pulmonary disease and secondary pulmonary arterial hypertension treated with Sildenafil versus those receiving only standard-of-care

The Egyptian Journal of Bronchology
Background Pulmonary arterial hypertension (PAH) is a common complication of chronic obstructive pulmonary disease (COPD), which can lead to shorter survival and poor clinical outcomes.

Comparative efficacy of combination therapy including regenerative therapies versus monotherapy for erectile dysfunction: A systematic review and meta‐analysis

Andrology, Volume 14, Issue 2, Page 358-367, February 2026.
Abstract Background and objective The Current European Association of Urology guidelines do not provide recommendation for combination of regenerative therapies with standard therapies for erectile dysfunction. The aim of this study was to compare the efficacy of combined regenerative therapy with monotherapy for erectile dysfunction.

The importin‐alpha superfamily engages in ethylene signaling by shuttling ETHYLENE INSENSITIVE 2 from the endoplasmic reticulum to the nucleus

The FEBS Journal, Volume 293, Issue 3, Page 894-917, February 2026.
The plant hormone ethylene regulates plant growth, ripening, senescence, and stress responses. The hormonal signal transmission, from receptors at the ER membrane to the transcriptional regulators in the nucleus, is still not completely understood.
