Testicular SIRT1 Loss Reveals an Aging‐Like Proteomic Landscape and Precipitates Reproductive Deterioration

Andrology, EarlyView.
ABSTRACT Background Advanced paternal age is associated with reduced male fertility and testicular dysfunction. Among the molecular regulators involved in aging, SIRT1, a NAD+‐dependent deacetylase, plays a pivotal role in maintaining oxidative balance and cellular homeostasis.

Hyperpolarized MRI theranostics in cancer

Frontiers in Oncology
Hyperpolarized magnetic resonance imaging (MRI) has emerged as a transformative tool in cancer diagnostics, enabling real-time, non-invasive assessment of tumor metabolism. By employing hyperpolarized molecular probes, such as [1- 13 C]pyruvate, energy metabolism and metabolic changes ...

Non‐canonical PKG1 regulation in cardiovascular health and disease

British Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.

Is there a role for cannabidiol in obesity, metabolic syndrome and binge eating?

British Journal of Pharmacology, EarlyView.
Cannabidiol (CBD) is one of the most abundant phytocannabinoids isolated from the Cannabis sativa plant. CBD is a lipophilic, non‐intoxicating substance that differently from Δ9‐tetrahydrocannabinol (Δ9‐THC) does not present the typical profile of a drug of abuse.

Flecainide binding dynamics in voltage‐gated sodium channels: A comparative isoform analysis of the state‐dependent block

British Journal of Pharmacology, EarlyView.
Background and Purpose Local anaesthetics and class I anti‐arrhythmic drugs block voltage‐gated Na+ channels, but the molecular basis for the isoform differences in drug sensitivity remains unclear. Understanding these mechanisms is essential for optimizing therapeutic efficacy and safety.

Targeting the noncatalytic activity of GSK3β modulates neuronal excitability in medium spiny neurons via Nav1.6 interactions

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Kinases phosphorylate ion channels, but their noncatalytic roles via protein–protein interactions (PPI) are less understood. Here, we identified the peptidomimetic ZL141 to characterize the PPI between GSK3β and Nav1.6, revealing a noncatalytic role for GSK3β in regulating Nav1.6 currents and neuronal excitability ...

A novel selective stabilizer of the ryanodine receptor 2 prevents stress‐induced ventricular arrhythmias without impairing cardiac function

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Aberrant activation of type 2 ryanodine receptors (RyR2) causes lethal arrhythmias, such as catecholaminergic polymorphic ventricular tachycardia (CPVT). Developing drugs that suppress RyR2 hyperactivation may be key to novel arrhythmia treatments.

Gβγ subunit activation of KV7 and BKCa channels underlies calcitonin gene‐related peptide vasorelaxation in myogenic rat coronary resistance arteries

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose CGRP is a potent, clinically relevant coronary vasodilator known to play a role in cardioprotection. Here, we investigated the precise intracellular signalling pathways leading to vasodilation in small coronary arteries.

Persistent in vitro nociceptor hyperexcitability and axonal retraction produced by repeated paclitaxel doses

The FEBS Journal, EarlyView.
Repeated paclitaxel exposure causes long‐lasting nociceptor hyperexcitability and axonal retraction in adult sensory neurons. Using a long‐term primary nociceptor culture, we show that hyperexcitability is mediated by sequential upregulation of NaV1.8, TRPV1, TRPA1, and TRPM8 channels.
