Precision therapies for genetic epilepsies in 2025: Promises and pitfalls

Epilepsia Open, EarlyView.
Abstract By targeting the underlying etiology, precision therapies offer an exciting paradigm shift to improve the stagnant outcomes of drug‐resistant epilepsies, including developmental and epileptic encephalopathies. Unlike conventional antiseizure medications (ASMs) which only treat the symptoms (seizures) but have no effect on the underlying ...

Responsiveness to progesterone and potassium channel blockers 4-aminopyridine, tetraethylammonium and free Ca(2+) contentration in spermatozoa of patients with oligozoospermia/leucocytospermia

The Ukrainian Biochemical Journal, 2018
The present study was undertaken to evaluate [Ca2+]i signals that occur in human sperm cells exposed in vitro to three diverse compounds; progesterone, 4-aminopyridine (a highly effective inducer of hyperactivation in human sperm) and tetraethylammonium.

Movement Disorders in Developmental and Epileptic Encephalopathies

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Monogenic developmental and epileptic encephalopathies (DEE) frequently feature co‐occurring movement disorders. Gene discovery has expanded epilepsy‐dyskinesia syndromes (EDS) from classic associations such as stereotypies in Rett syndrome to PRRT2‐related infantile seizures with paroxysmal dyskinesia and crouched gait in SCN1A ...

The photoswitchable ABAMIs for the future regulation of GWT1 in a spatiotemporal level

Smart Molecules, EarlyView.
The GWT1‐targeted azobenzene‐aminopyridine derivatives (ABAMIs), sensitive to the light at wavelengths from 365 to 520 nm, are separately developed as photochromic ligands to regulate bioactivity as well as the GWT1 functions. These molecules are smart tools in photopharmacological studies, giving an innovative method for understanding functional GWT1 ...

Amiodarone reduces depolarization-evoked glutamate release from hippocampual synaptosomes

Journal of Pharmacological Sciences, 2017
Decreased brain glutamate level has emerged as a new therapeutic approach for epilepsy. This study investigated the effect and mechanism of amiodarone, an anti-arrhythmic drug with antiepileptic activity, on glutamate release in the rat hippocampus. In a

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.

Role of K+ Channels in M2 Muscarinic Receptor-Mediated Inhibition of Noradrenaline Release From the Rat Stomach

Journal of Pharmacological Sciences, 2004
Previously we reported the cholinergic M2 muscarinic receptor-mediated inhibition of noradrenaline release from the rat stomach (K. Yokotani, Y. Osumi. J Pharmacol Exp Ther. 1993;264:54–60).

The mechanics of hyperactivation in adhered human sperm [PDF]

Royal Society Open Science, 2014
Hyperactivation is an important phenomenon exhibited by mammalian sperm during the process of acquiring fertilization capacity. The majority of studies have focused on incubation-induced hyperactivation in non-human species, which typically differ in ...

GAA‐FGF14 Ataxia Is a Frequently Overlooked Cause of Sporadic Adult‐Onset Ataxia

Clinical Genetics, EarlyView.
GAA‐FGF14 ataxia is a frequent cause of both familial and sporadic cerebellar ataxia. If symptoms are consistent, targeted testing of the FGF14 locus should be considered as a first‐line approach, as the diagnostic yield is up to 50%. ABSTRACT GAA‐FGF14 ataxia (spinocerebellar ataxia 27B, SCA27B), identified in 2023, is a major cause of adult‐onset ...

Inhibition of 4-aminopyridine-induced seizures in mice by a novel 3-substituted 1,4-benzodiazepine

Фармацевтичний журнал, 2019
Some of highly effective antiepileptic substances share the polymodal pharmacological action which determines the possibility of their use for treatment of pathogenetically similar diseases. Inhibitory mediator systems influence for example, suggests the
