Valproic acid (VPA) is a short-chain fatty acid commonly used for treatment of neurological disorders. As VPA can interfere with cellular lipid metabolism, its effect on the infection of cultured cells by viruses of seven viral families relevant to human and animal health, including eight enveloped and four nonenveloped viruses, was analyzed. VPA drastically inhibited multiplication of all the ...
Valproic acid (VPA), a branched short-chain fatty acid, is widely used as an antiepileptic drug and a mood stabilizer. Antiepileptic properties have been attributed to inhibition of Gamma Amino Butyrate (GABA) transaminobutyrate and of ion channels. VPA was recently classified among the Histone Deacetylase Inhibitors, acting directly at the level of gene transcription by inhibiting histone deac...
Valproic acid (VPA) is an effective and widely used anticonvulsant, associated with metabolic adverse effects such as weight gain, hyperinsulinemia, hyperleptinemia and hypoadiponectinemia. The aim of this study was to evaluate the influence of VPA and topiramate (TPM) on adiponectin binding receptors, adipoR1 and adipoR2, in human liver cancer cells, HepG2. AdipoR1 but not adipoR2 gene express...
The aim of this study was to evaluate the effects of valproic acid (VPA), as a histone deacetylase inhibitor, on myeloma cell lines and on sorted human bone marrow multiple myeloma cells. VPA induced accumulation of acetylated histones, potently inhibited proliferation in a dose-dependent manner and induced apoptosis in all myeloma cell lines tested as well as in sorted primary multiple myeloma...
Effect of histone deacetylase inhibitor valproic acid on progenitor cells of acute myeloid leukemia.
Histone deacetylase inhibitor valproic acid (VPA) was recently shown to enhance proliferation and self-renewal of normal hematopoietic stem cells, raising the possibility that VPA may also support growth of leukemic progenitor cells (LPC). Here, VPA maintains a significantly higher proportion of CD34+ LPC and colony forming units compared to control cultures in six AML samples, but selectively ...
Valproic acid (VPA) is a broad-spectrum antiseizure drug used for a variety of clinical conditions, such as epilepsy and mood disorders. Drug-induced hypersensitivity syndrome (DRESS) accompanied by hyponatremia, thrombocytopenia, hypoalbuminemia and elevated aminotransferase has never been reported as an adverse effect of VPA monotherapy during titration for epilepsy in Asian population. Hereb...
valproic acid (vpa) is one of the mostly used antiepileptic drugs that may have some side effects so, it is highly recommended to evaluate its serum concentrations. the aim of this study was to develop a simple, fast and economic method using gas-chromatography equipped with flame ionization detector (gc/fid) and vpa analysis. to do this, 200 µl of serum was mixed with an aliquot of caproic aci...
Valproic acid (VPA), widely used in treating epileptic patients, can damage reproductive parameters causing male infertility. This study aimed to investigate protective effect of Phyllanthus emblica L. branch (PE) extract on rat testicular damage induced with VPA. Male rats were divided into 6 groups (control, VPA, 250 mg/kgBW PE only, and 50, 100, 250 mg/kgBW PE+VPA, respectively). Animals wer...
It has become apparent that chromatin modification plays a critical role in the regulation of cell-type-specific gene expression. Here, we show that an inhibitor of histone deacetylase, valproic acid (VPA), induced neuronal differentiation of adult hippocampal neural progenitors. In addition, VPA inhibited astrocyte and oligodendrocyte differentiation, even in conditions that favored lineage-sp...
Plasma levels of valproic acid (VPA) are decreased by concomitant use with carbapenem antibiotics, such as panipenem (PAPM). One of the plausible mechanisms of this interaction is the inhibition of VPA glucuronide (VPA-G) hydrolysis by carbapenems in the liver. To elucidate this interaction mechanism, we purified VPA-G hydrolase from human liver cytosol, in which the hydrolytic activity was mai...
