BACKGROUND
Valproic acid (VPA) is a histone deacetylase inhibitor that may decrease cellular metabolic needs following traumatic injury. We hypothesized that VPA may have beneficial effects in preventing or reducing the cellular and metabolic sequelae of ischemia-reperfusion
BACKGROUND
Pharmacological histone deacetylase (HDAC) inhibitors, such as known anticonvulsant valproic acid (VPA), demonstrate cytoprotective effects and increase acetylation of nuclear histones, promoting transcriptional activation of deregulated genes. Therefore, we examined protective effects of
Pharmacological inhibitors of histone deacetylases (HDAC) demonstrate cytoprotective effects both in vitro and in vivo. In this study, we investigated whether valproic acid (VPA), a known mood stabilizer and anticonvulsant with HDAC-inhibiting activity, improves survival following otherwise lethal
OBJECTIVE
To investigate the consequences of histone deacetylase inhibition by histone deacetylase inhibitor valproic acid and IκB kinase/nuclear factor-κB signaling blockade by IκB kinase inhibitor BAY11-7082 on (microvascular) endothelial cell behavior in vitro as well as in mice subjected to
BACKGROUND
DNA transcription is regulated in part by acetylation of nuclear histones, controlled by 2 groups of enzymes: histone deacetylases (HDAC) and histone acetyl transferases (HAT). We have shown previously that hemorrhage and resuscitation are associated with HDAC/HAT imbalance, which
BACKGROUND
We have previously shown that resuscitation with fresh frozen plasma (FFP) in a large animal model of traumatic brain injury (TBI) and hemorrhagic shock (HS) decreases the size of the brain lesion, and that addition of a histone deacetylase inhibitor, valproic acid (VPA), provides
Isoform-specific histone deacetylase inhibitors (HDACIs) MC1568 and ACY1083 are comparable to the non-selective HDACI valproic acid (VPA) in improving survival in rodents undergoing lethal hemorrhage. However, the organ-specific properties of isoform-specific HDACIs have not been fully We recently discovered that Tubastatin-A, a histone deacetylase (HDAC6) inhibitor, can improve survival in a rodent model of hemorrhagic shock (HS), but mechanisms remain poorly defined. In this study, we investigated whether Tubastatin-A could protect intestinal tight junction (TJ) in HS.
In an
BACKGROUND
We have previously demonstrated that treatment with histone deacetylase inhibitors (HDACI), such as valproic acid (VPA) and suberoylanilide hydroxamic acid (SAHA), can improve survival after hemorrhagic shock in animal models. Hemorrhage results in hypoacetylation of proteins which is
The pharmacokinetics and acute toxicity of a histone deacetylase inhibitor, Scriptaid, was unknown in mouse. The aim of this study was to determine the pharmacokinetics, acute toxicity, and tissue distribution of Scriptaid, a new histone deacetylase inhibitor, in mice, and its BACKGROUND
Hemorrhage is the leading cause of preventable trauma-related deaths. We have previously shown that treatment with Tubastatin A (Tub A), a histone deacetylase 6 (HDAC6) inhibitor, can improve survival in a rodent model of septic shock. The aims of the present study were to determine
BACKGROUND
DNA transcription is regulated, in part, by acetylation of nuclear histones that are controlled by 2 groups of enzymes: histone deacetylases (HDAC) and histone acetyl transferases (HAT). Whether an imbalance in HDAC/HAT system plays a role in hemorrhage/resuscitation is unknown. The goals
BACKGROUND
Hemorrhage is a leading preventable cause of death. Nonselective histone deacetylase inhibitors (HDACIs), such as valproic acid (VPA), have been shown to improve outcomes in hemorrhagic shock (HS). The HDACs can be divided into four functional classes (I, IIa/IIb, III, and IV). Classes I,
BACKGROUND
We have demonstrated that valproic acid (VPA), a histone deacetylase inhibitor (HDACI), can improve animal survival after hemorrhagic shock, and protect neurons from hypoxia-induced apoptosis. This study investigated whether VPA treatment works through the c-Jun N-terminal kinase
BACKGROUND
Chromatin remodeling through histone acetylation is a key control mechanism in gene transcription. We have shown previously that fluid resuscitation in rodents is coupled with highly structured post-translational modifications of cardiac histones. The current experiment was performed to
