hydroxamic acid/hemorrhage

Spontaneous intracerebral hemorrhage (ICH) is a stroke subtype with no effective treatment. Though ICH is known to induce severe neurological damage, the molecular mechanisms of neurological injury after ICH remain largely unclear. Given the emerging role of epigenetic mechanisms in

BACKGROUND Hemorrhage induces an imbalance in histone acetyl transferase/histone deacetylase (HAT/HDAC) ratio. Correction of this imbalance with histone deacetylase inhibitors (HDACI) improves survival. We aimed to identify whether this was due to modulation of the post-shock immune

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

OBJECTIVE To explore the protection and molecular mechanism of histone deacetylase inhibitors (HDACIs) on the spleen of rats with hemorrhagic shock. METHODS A total of 60 SPF male SD rats were selected for the modeling of severe hemorrhagic shock using the method of arterial and venous cannulation

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

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 Patients with massive blood loss often die before delivery of definitive care, especially in austere environments. Strategies that can maintain life during evacuation and transport to higher levels of care may be lifesaving. We have previously shown that administration of histone

We have recently found that suberoylanilide hydroxamic acid (SAHA), a histone deacetylase inhibitor, improves survival in a lethal model of hemorrhagic shock in rats. The purpose of the present study was to determine whether SAHA treatment would prevent LPS-induced septic shock and improve the

Hemorrhagic cystitis is an inflammatory and ulcerative bladder condition associated with systemic chemotherapeutics, like cyclophosphomide. Earlier, we reported reactive oxygen species resulting from cyclophosphamide metabolite, acrolein, causes global methylation followed by silencing of DNA damage

After spinal cord injury (SCI), blood-spinal cord barrier (BSCB) disruption by matrix metalloproteinases (MMPs) leads to BSCB permeability and blood cell infiltration, contributing to permanent neurological disability. Herein, we report that MMP-3 plays a critical role in BSCB disruption after SCI

BACKGROUND Histone deacetylases (HDAC) catalyze N-terminal deacetylation of lysine-residues on histones and multiple nuclear and cytoplasmic proteins. In various animal models, such as trauma/hemorrhagic shock, ischemic stroke or myocardial infarction, HDAC inhibitor (HDACi) application is cyto- and

Chronic pain after traumatic brain injury (TBI) is very common, but the mechanisms linking TBI to pain and the pain-related interactions of TBI with peripheral injuries are poorly understood. In these studies we pursued the hypothesis that TBI pain sensitization is associated with histone

Grass carp (Ctenopharyngodon idellus) is an important worldwide commercial freshwater culture species. However, grass carp reovirus (GCRV) causes serious hemorrhagic disease in fingerlings and yearlings of fishes. To understand the molecular pathogenesis of host cells during GCRV infection,

BACKGROUND Histone deacetylase inhibitors (HDACI), can improve survival after lethal hemorrhagic shock, and modulate the inflammatory response after hemorrhage/lipopolysaccharide (LPS). The current experiments were designed to study the effects of HDACI after hemorrhage and severe
