Targeting epigenetic changes in diffuse intrinsic pontine glioma (DIPG) may provide a novel treatment option for patients. This report demonstrates that sodium valproate, a histone deacetylase inhibitor (HDACi), can increase the cytotoxicity of carboplatin in an additive and synergistic manner in DIPG cells in vitro. Sodium valproate causes a dose-dependent decrease in DIPG cell viability in three independent ex vivo cell lines. Furthermore, sodium valproate caused an increase in acetylation of histone H3. Changes in cell viability were consistent with an induction of apoptosis in DIPG cells in vitro, determined by flow cytometric analysis of Annexin V staining and assessment of apoptotic markers by western blotting...

A body of evidence supports a relevant role of brain-derived neurotrophic factor (BDNF) in temporal lobe epilepsy (TLE). Magnetic resonance data reveal that the cerebral atrophy extends to regions that are functionally and anatomically connected with the hippocampus, especially the temporal cortex. We previously reported an increased expression of BDNF messenger for the exon VI in the hippocampus of temporal lobe epilepsy patients compared to an autopsy control group. Altered levels of this particular transcript were also associated with pre-surgical use of certain psychotropic...

INTRODUCTION: Resistance to treatments is a common feature of Ohtahara, Aicardi, West and Dravet syndromes, as well as malignant migrating epilepsy in infancy. AIMS: To update the therapeutic management and to analyse whether the aetiology somehow determines the treatment. DEVELOPMENT: Convulsive seizures in the first year of life may be due to a potentially treatable aetiology, which makes it essential to carry out a complete evaluation so as to be able to begin, as early as possible, the most suitable and the non-specific symptomatic treatments to control the seizures, which prevents or minimises their deleterious effects...

Usually performed in the mouse, the 6Hz seizure test is used for screening potential new anticonvulsant substances against complex partial seizures. Nevertheless, advanced models of temporal lobe epilepsy (TLE) are more often performed in rats, so that possible species-related differences may complicate the development of anticonvulsant substances. The aim of the present study was to evaluate the feasibility of adapting the 6Hz test in the rat. We first compared the effects of increasing current intensities for inducing seizures in the mouse and in the rat...

INTRODUCTION: Analgesics are commonly prescribed medications used to alleviate pain of various aetiologies without affecting the patient's consciousness. They interfere with the transmission of pain signals. A commonly used antiepileptic drug, sodium valproate has been used in various non-epileptic conditions like migraine prophylaxis and in the treatment of bipolar disorder because of the multiple mechanisms by which it acts. Docosahexanoic Acid (DHA), an omega 3 fatty acid, is known to possess analgesic activity...

BACKGROUND: Valproic acid (VPA), used for treating bipolar disorder (BD), is teratogenic by inhibiting histone deacetylase. In unanaesthetized rats, chronic VPA, like other mood stabilizers, reduces arachidonic acid (AA) turnover in brain phospholipids, and inhibits AA activation to AA-CoA by recombinant acyl-CoA synthetase-4 (Acsl-4) in vitro. Valnoctamide (VCD), a non-teratogenic constitutional isomer of VPA amide, reported effective in BD, also inhibits recombinant Acsl-4 in vitro...

Valproic acid (VPA) is widely used for treatment of epilepsy. However, its overdose can cause intoxication and could be life-threatening. Due to lack of specific antidote and poorness of endogenous clearance, extracorporeal treatment for severe intoxication cases is indicated. Here, we report a case of severe intoxication of VPA which was successfully treated with liver support therapy. A previously healthy woman was admitted due to coma and hypotension after intentional ingestion of 20 g of sodium valproate...

PTPN6, a tyrosine phosphatase protein, plays a negative role in cell signal transduction and is negatively correlated with tumour formation and growth. However, epigenetic regulation mechanism of the PTPN6 gene in advanced chronic myeloid leukaemia (CML) remains unclear. This study investigated bone marrow or blood samples from 44 CML patients and 10 healthy volunteers. KCL22 and K562 cells were cultured and treated with demethylation drugs and histone deacetylase inhibitors. Real time quantitative polymerase chain reaction (qPCR), methylation-specific PCR, bisulfite sequencing PCR, Western blotting, co-immunoprecipitation and chromatin immunoprecipitation (ChIP) was performed...

BACKGROUND: Epilepsy is a disorder of the central nervous system characterized by recurrent seizures. It is a very common disease in which approximately 30% of patients do not respond favourably to treatment with anticonvulsants. Oxidative stress is associated with neuronal damage arising from epileptic seizures. The present study investigated the effects of naringenin in pilocarpine-induced epilepsy in mice. Naringenin, one of the most frequently occurring flavanone in citrus fruits, was evaluated for its shielding effect against the pilocarpine induced behavioural, oxidative and histopathological alterations in rodent model of epilepsy...

BACKGROUND: The management of depressive and mixed symptoms in children and adolescents with bipolar disorder (BD) remains a matter of debate. The goal of this review is, thus, to systematically examine the impact of atypical antipsychotics (AAPs) and mood stabilisers in the treatment of bipolar depression and/or mixed states. METHODS: A literature search was conducted for studies assessing the efficacy of pharmacological treatments for bipolar disorder type I, type II and not otherwise specified with a recent depressive, mixed or manic episode (with depressive symptoms) following DSM-IV criteria in children and adolescents as either acute or maintenance treatment...

BACKGROUND: Pregnant women with epilepsy frequently experience seizures related to pregnancy complications and are often prescribed anti-epileptic drugs (AEDs) to manage their symptoms. However, less is known about the comparative safety of AED exposure in utero. We aimed to compare the risk of congenital malformations (CMs) and prenatal outcomes of AEDs in infants/children who were exposed to AEDs in utero through a systematic review and Bayesian random-effects network meta-analysis...

Valproate (VPA) is an antiepileptic drug (AED) used for initial monotherapy in treating childhood absence epilepsy (CAE). EEG might be an alternative approach to explore the effects of AEDs on the central nervous system. We performed a comparative analysis of background EEG activity during VPA treatment by using standardized, low-resolution, brain electromagnetic tomography (sLORETA) to explore the effect of VPA in patients with CAE. In 17 children with CAE, non-parametric statistical analyses using sLORETA were performed to compare the current density distribution of four frequency bands (delta, theta, alpha, and beta) between the untreated and treated condition...

Early maladaptive internalization of synaptic GABAA receptors (GABAAR) and externalization of NMDA receptors (NMDAR) may explain the time-dependent loss of potency of standard anti-epileptic drugs (AED) in refractory status epilepticus (SE). We hypothesized that correcting the effects of changes in GABAAR and NMDAR would terminate SE, even when treatment is delayed 40 minutes. SE was induced in adult Sprague-Dawley rats with a high dose of lithium and pilocarpine. The GABAAR agonist midazolam, the NMDAR antagonist ketamine and the AED valproate were injected 40 min after SE onset in combination or as monotherapy...

We explored the influence of four different efficacy criteria on the results of observational studies concerning the treatment of status epilepticus (SE) and its subtypes. We compared and contrasted the results of four different efficacy criteria for the effectiveness of phenytoin, valproate, levetiracetam, and lacosamide. Criterion 1=the last antiepileptic drug (AED) administered before SE termination. Criterion 2=the last drug introduced into the antiepileptic therapy within 72h before the cessation of SE and without changes in dosage or number of the co-medication...

OBJECTIVE: The mouse 6 Hz model of psychomotor seizures is a well-established and commonly used preclinical model for antiseizure drug (ASD) discovery. Despite its widespread use both in the identification and differentiation of novel ASDs in mice, a corresponding assay in rats has not been developed. We established a method for 6 Hz seizure induction in rats, with seizure behaviors similar to those observed in mice including head nod, jaw clonus, and forelimb clonus. METHODS: A convulsive current that elicits these seizure behaviors in 97% of rats (CC97 ) was determined using a Probit analysis...
