    ABSTRACT: We demonstrated recently that treatment with suberoylanilide hydroxamic acid (SAHA), a histone deacetylase inhibitor, improved survival in a rodent model of lipopolysaccharide (LPS)-induced endotoxic shock. The precise mechanisms, however, have not been well-defined. The aim of this study was to investigate the impact of SAHA treatment on gene expression profiles at an early stage of shock. Male C57BL/6J mice were treated with or without SAHA (50 mg/kg, IP), followed by a lethal dose of LPS (20 mg/kg, IP) and a second dose of SAHA. Lungs of the animals (LPS and SAHA+LPS groups; n = 3 per group) were harvested 3 hours post-LPS insult. Sham mice (no LPS and no SAHA) served as controls. RNA was isolated from the tissues and gene expression was analyzed using Affymatrix microarray (23,000 genes). A lower confidence bound of fold change was determined for comparison of LPS versus SAHA + LPS, and genes with a lower confidence bound of >2 were considered to be differentially expressed. Reverse transcriptase polymerase chain reaction, Western blotting, and tissue staining were performed to verify the key changes. Network graphs were used to determine gene interaction and biologic relevance. The expression of many genes known to be involved in septic pathophysiology changed after the LPS insult. Interestingly, a number of genes not implicated previously in the septic response were also altered. SAHA treatment attenuated expression of several key genes involved in inflammation. It also decreased neutrophil infiltration in lungs and histologic evidence of acute lung injury. Further analysis confirmed genes engaged in the cellular and humoral arms of the innate immune system were specifically inhibited by SAHA. Gene network analysis identified numerous molecules for the potential development of targeted therapies. Administration of SAHA in a rodent model of LPS shock rapidly modulates gene transcription, with an attenuation of inflammatory mediators derived from both arms (cellular and humoral) of the innate immune system. This may be a novel mechanism responsible for the survival advantage seen with SAHA treatment.

    ABSTRACT: Objective: We have previously demonstrated that pretreatment and posttreatment of animals with suberoylanilide hydroxamic acid (SAHA), a histone deacetylase inhibitor, can improve survival in a mouse model of lipopolysaccharide (LPS)-induced severe shock. This study was designed to assess whether SAHA affects LPS/Toll-like receptor 4 signaling through acetylation of heat shock protein 90 (HSP90) and degradation of its client protein interleukin-1 receptor-associated kinase 1 (IRAK1). Methods: RAW264.7 cells were exposed to LPS (1 μg/mL) for 2 h, followed by treatment with SAHA (10 μM) or geldanamycin (3 μM), an inhibitor of HSP90. Sham (no SAHA, no LPS) macrophages served as a control. The cells were harvested at different time points, and time zero served as the reference point. Results: LPS dramatically increased protein expression of myeloid differentiation factor 88 and IRAK1, and stimulated nuclear translocation of nuclear factor κB, leading to an increases of gene expression and protein production of tumor necrosis factor α and interleukin-6. Treatment with SAHA significantly attenuated these LPS-stimulated alterations. LPS or SAHA did not change the levels of HSP90 protein, but immunoprecipitation studies demonstrated that SAHA treatment enhanced acetylation of HSP90, and increased the dissociation of IRAK1, compared to the LPS control. Conclusions: SAHA suppresses LPS/Toll-like receptor 4 signaling in LPS-stimulated macrophages through multiple potential mechanisms. It inhibits the function of HSP90 through hyperacetylation of the chaperone protein, which results in dissociation and degradation of the client protein IRAK1 and, at least in part, leads to a decrease in nuclear translocation of nuclear factor κB and attenuation of key proinflammatory cytokine expression.

    ABSTRACT: Acute lung injury (ALI) is a complication of hemorrhagic shock (HS). Histone deacetylase inhibitors, such as valproic acid (VPA), can improve survival after HS; however, their effects on late organ injury are unknown. Herein, we have investigated the effects of HS and VPA treatment on ALI and circulating cytokines that may serve as biomarkers for the development of organ injury. Anesthetized Wistar-Kyoto rats (250-300 g) underwent 40% blood volume hemorrhage over 10 minutes followed by 30 minutes of unresuscitated shock and were treated with either VPA (300 mg/kg) or vehicle control. Blood samples were obtained at baseline, after shock, and before death (at 1, 4, and 20 hours; n = 3-4/timepoint/group). Serum samples were screened for possible biomarkers using a multiplex electrochemiluminescence detection assay, and results were confirmed using enzyme-linked immunosorbent assay (ELISA). In addition, lung tissue lysate was examined for chemokine and myeloperoxidase (MPO) levels as a marker for neutrophil infiltration and ALI. Lung cytokine-induced neutrophil chemoattractant-1 (CINC-1; a chemokine belonging to the interleukin-8 family that promotes neutrophil chemotaxis) mRNA levels were measured by real-time polymerase chain reaction studies. Serum screening revealed that hemorrhage rapidly altered levels of circulating CINC-1. ELISA confirmed that CINC-1 protein was significantly elevated in the serum as early as 4 hours and in the lung at 20 hours after hemorrhage, without any significant changes in CINC-1 mRNA expression. Lung MPO levels were also elevated at both 4 and 20 hours after hemorrhage. VPA treatment attenuated these changes. Hemorrhage resulted in the development of ALI, which was prevented with VPA treatment. Circulating CINC-1 levels rose rapidly after hemorrhage, and serum CINC-1 levels correlated with lung CINC-1 and MPO levels. This suggests that circulating CINC-1 levels could be used as an early marker for the subsequent development of organ inflammation and injury.

    ABSTRACT: Circulating proteins may serve as biomarkers for the early diagnosis and treatment of shock. We have recently demonstrated that treatment with suberoylanilide hydroxamic acid (SAHA), a histone deacetylase inhibitor, significantly improves survival in a rodent model of lipopolysaccharide (LPS)-induced septic shock. Preliminary proteomic data showed that LPS-induced shock altered a number of proteins in circulation, including histone H3 (H3) and citrullinated histone H3 (Cit H3). The present study was designed to confirm these findings and to test whether the pro-survival phenotype could be detected by an early alteration in serum biomarkers. Three experiments were performed. In experiment I, Western blotting was performed on serum samples from male C57B1/6J mice (n = 9, 3/group) that belonged to the following groups: (a) LPS (20 mg/kg)-induced septic shock, (b) SAHA-treated septic shock, and (c) sham (no LPS, no SAHA). In experiment II, HL-60 granulocytes were cultured and treated with LPS (100 ng/m1) in the absence or presence of SAHA (10 μmol/L). Sham (no LPS, no SAHA) granulocytes served as controls. The medium and cells were harvested at 3 hours, and proteins were measured with Western blots. In experiment III, a large dose (LD, 35 mg/kg) or small dose (SD, 10 mg/kg) of LPS was injected intraperitoneally into the C57B1/6J mice (n = 10 per group). Blood was collected at 3 hours, and serum proteins were determined by Western blots or enzyme-linked immunosorbent assay (ELISA). All of the Western blots were performed with antibodies against H3, Cit H3, and acetylated H3 (Ac H3). ELISA was performed with antibody against tumor necrosis factor (TNF)-α. Survival rates were recorded over 7 days. In experiment I, intraperitoneal (IP) injection of LPS (20 mg/kg) significantly increased serum levels of H3, which was prevented by SAHA treatment. In experiment II, LPS (100 ng/mL) induced expression and secretion of Cit H3 and H3 proteins in neutrophilic HL-60 cells, which was decreased by SAHA treatment. In experiment III, administration of LPS (LD) caused a rise in serum H3 and Cit H3 but not Ac H3 at 3 hours, and all of these animals died within 23 hours (100% mortality). Decreasing the dose of LPS (SD) significantly reduced the mortality rate (10% mortality) as well as the circulating levels of Cit H3 (non detectable) and H3. An increase in serum TNF-α was found in both LPS (LD) and (SD) groups, but in a non-dose-dependent fashion. Our results reveal for the first time that Cit H3 is released into circulation during the early stages of LPS-induced shock. Moreover, serum levels of Cit H3 are significantly associated with severity of LPS-induced shock. Therefore, Cit H3 could serve as a potential protein biomarker for early diagnosis of septic shock, and for predicting its lethality.

    ABSTRACT: Hemorrhagic shock activates cellular stress signals and can lead to systemic inflammatory response, organ injury, and death. We have previously shown that treatment with histone deacetylase inhibitors (HDACIs) significantly improves survival in lethal models (60% blood loss) of hemorrhage. The aim of the current study was to examine whether these protective effects were due to attenuation of mitogen activated protein kinase (MAPK) signaling pathways, which are known to promote inflammation and apoptosis. Wistar-Kyoto rats (250-300 g) were subjected to 40% blood loss and randomized to treatment with: (1) HDACI valproic acid (VPA 300 mg/kg i.v.; volume = 0.75 mL/kg), or (2) vehicle control (0.75 mL/kg of 0.9% saline). Animals were sacrificed at 1, 4, and 20 h (n = 3-4/group/timepoint), and lung samples were analyzed by Western blotting for expression of active (phosphorylated) and inactive forms of c-Jun N-terminal Kinase (JNK) and p38 MAPK. Myeloperoxidase (MPO) activity was measured in lung tissue 20 h after hemorrhage as a marker of neutrophil infiltration. Normal animals (n = 3) served as shams. Hemorrhaged animals demonstrated significant increases in phosphorylated p38 at 1 h, phosphorylated JNK at 4 h, and increased MPO activity at 20 h (P < 0.05 compared with sham). VPA treatment significantly (P < 0.05) attenuated all of these changes. Hemorrhagic shock activates pro-inflammatory MAPK signaling pathways and promotes pulmonary neutrophil infiltration, affects that are significantly attenuated by VPA treatment. This may represent a key mechanism through which HDACIs decrease organ damage and promote survival in hemorrhagic shock.

    ABSTRACT: We have previously demonstrated that valproic acid (VPA), a histone deacetylase inhibitor, and spray-dried plasma (SDP) improve early survival after lethal hemorrhage and polytrauma, but their effect on long-term survival and organ function remains untested. Yorkshire swine (n=27; 6-8/group) underwent a protocol simulating different phases of trauma care: (1) prehospital-rib fracture, soft-tissue injury, hemorrhage (50% blood volume), 30 minutes of shock, and infusion of 0.9% saline (3× shed blood); (2) early hospital/treatment-grade IV liver (partial amputation of the median lobe) and grade V splenic (transection of spleen into three pieces) injuries to simulate rupture of contained hematomas, followed by 30 minutes of uncontrolled hemorrhage. Animals were treated with (a) Hextend (6% hetastarch), (b) fresh whole blood (FWB), (c) SDP, and (d) VPA (300 mg/kg) plus Hextend. VPA was given during the prehospital phase, and the volumes of Hextend, FWB and SDP (reconstituted in water) matched shed blood; (3) repair/resuscitation-liver injury was controlled by suture control of the transected edge, and splenic injury was treated by partial splenectomy; 1 hour after repair of injuries, surviving animals were fully resuscitated with packed red blood cells; and (4) monitoring-survival was monitored for 7 days (primary endpoint), and blood samples were drawn serially to measure organ function. Only 25% of the Hextend-treated animals survived. Addition of VPA improved survival to only 50% (p=0.28), whereas treatment with SDP and FWB increased survival significantly to 83% and 100%, respectively (p<0.05). Surviving animals showed no long-term organ dysfunction, postoperative hemorrhage, and delayed complications. In a clinically relevant lethal polytrauma model, administration of SDP significantly improves survival without any long-term organ dysfunction or complications.

    ABSTRACT: Trauma-associated coagulopathy carries an extremely high mortality. Fresh-frozen plasma (FFP) is the mainstay of treatment; however, its availability in the battlefield is limited. We have already shown that lyophilized, freeze-dried plasma (FDP) reconstituted in its original volume can reverse trauma-associated coagulopathy. To enhance the logistical advantage (lower volume and weight), we developed and tested a hyperoncotic, hyperosmotic spray-dried plasma (SDP) product in a multiple injuries/hemorrhagic shock swine model. Plasma separated from fresh porcine blood was stored as FFP or preserved as FDP and SDP. In in vitro testing, SDP was reconstituted in distilled water that was either equal (1 × SDP) or one-third (3 × SDP) the original volume of FFP. Analysis included measurements of prothrombin time (PT), partial thromboplastin time (PTT), fibrinogen levels, and activity of selected clotting factors. In in vivo testing, swine were subjected to multiple injuries (femur fracture and grade V liver injury) and hemorrhagic shock (60% arterial hemorrhage, with the "lethal triad" of acidosis, coagulopathy, and hypothermia) and were treated with FFP, FDP, or 3 × SDP (n=4-5/group). Coagulation profiles (PT, PTT, and thromboelastography) were measured at baseline, post-shock, post-crystalloid, treatment (M0), and during 4 hours of monitoring (M1-4). In vitro testing revealed that clotting factors were preserved after spray drying. The coagulation profiles of FFP and 1 × SDP were similar, with 3 × SDP showing a prolonged PT/PTT. Multiple injuries/hemorrhagic shock produced significant coagulopathy, and 3 × SDP infusion was as effective as FFP and FDP in reversing it. Plasma can be spray dried and reconstituted to one-third of its original volume without compromising the coagulation properties in vivo. This shelf-stable, low-volume, hyperoncotic, hyperosmotic plasma is a logistically attractive option for the treatment of trauma-associated coagulopathy in austere environments, such as a battlefield.

    ABSTRACT: Despite global efforts to improve the treatment of sepsis, it remains a leading cause of morbidity and mortality in intensive care units. We have previously shown that suberoylanilide hydroxamic acid (SAHA), a histone deacetylase inhibitor, markedly improves survival in a murine model of lipopolysaccharide (LPS)-induced shock. SAHA has anti-inflammatory properties that have not been fully characterized. The liver plays an important role in the production of acute phase reactants involved in the inflammatory cascade and is also one of the major organs that can become dysfunctional in septic shock. The purpose of this study was to assess the effect of SAHA treatment on MAP kinases and associated inflammatory markers in murine liver after LPS-induced injury. C57B1/6J mice were randomly divided into three groups: (A) experimental-given intraperitoneal (i.p.) SAHA (50 mg/kg) in dimethyl sulfoxide (DMSO) vehicle solution (n = 12); (B) control- given vehicle only (n = 12), and; (C) sham-given no treatment (n = 7). Two hours later, experimental and control mice were injected with LPS (20 mg/kg, i.p.) and experimental mice received a second dose of SAHA. Livers were harvested at 3, 24, and 48 h for analysis of inflammatory markers using Western Blot, Polymerase Chain Reaction (PCR), and Enzyme-Linked Immunosorbent Assay (ELISA) techniques. After 3 h, the livers of animals treated with SAHA showed significantly (P < 0.05) decreased expression of the pro-inflammatory MAP kinases phosphorylated p38, phosphorylated ERK, myeloperoxidase and interleukin-6, and increased levels of the anti-inflammatory interleukin-10 compared with controls. Phospho-p38 expression remained low in the SAHA treated groups at 24 and 48 h. Administration of SAHA is associated with attenuation of MAPK activation and alteration of inflammatory and anti-inflammatory markers in murine liver after a lethal LPS insult. The suppression of MAPK activity is rapid (within 3 h), and is sustained for up to 48 h post-treatment. These results may in part account for the improvement in survival shown in this model.

    ABSTRACT: Hemorrhage is the leading cause of preventable trauma-related deaths, and histone deacetylase inhibitors (HDACI) such as valproic acid (VPA) can improve survival following lethal hemorrhage. HDACI acetylate proteins, and acetylation regulates many cellular functions. Here we have investigated the effects of VPA treatment on extracellular signal-regulated kinase 1/2 (ERK) activation, as ERK is well known to modulate cell death, gene expression, and inflammation. Anesthetized Wistar-Kyoto rats were subjected to lethal (60%) blood loss, and then randomized (n = 5-6/group) to (1) VPA 300 mg/kg or (2) vehicle control. Survival was monitored for 24 h. A separate group of rats were subjected to sublethal (40%) hemorrhage and were treated with VPA or vehicle. Rats were sacrificed at 1, 4, and 20 h, and lung tissue was assessed for the degree of acetylation of histone 3, and activation (phosphorylation) of ERK. Sham animals served as normal controls. Sixty percent hemorrhage resulted in severe shock. Only 17% of the vehicle-treated animals survived (most died within 1 h), whereas 80% of the VPA-treated animals survived (P < 0.05). Hemorrhage resulted in a significant increase in phosphorylated ERK (activated form) compared with sham at the 1 and 4 h time points, but not at the 20 h time point. VPA treatment significantly attenuated these changes, while increasing histone protein acetylation. VPA treatment significantly improves survival following lethal hemorrhagic shock. Hemorrhage induces ERK activation, which is significantly attenuated by VPA treatment. This may represent one mechanism through which VPA promotes survival in otherwise lethal hemorrhagic shock.

    ABSTRACT: We have recently demonstrated that treatment with suberoylanilide hydroxamic acid (SAHA), a histone deacetylase inhibitor, before a lethal dose of lipopolysaccharide (LPS) improves survival in mice. The purpose of the present study was to determine whether SAHA treatment would attenuate LPS-induced shock and improve survival when given postinsult in a rodent model. C57BL/6J mice were intraperitoneally (IP) injected with LPS (30 mg/kg), and 2 hours later randomized into 2 groups: (1) vehicle animals (n = 10) received dimethyl sulfoxide (DMSO) solution only; and (2) SAHA animals (n = 10) were given SAHA (50 mg/kg, IP) in DMSO solution. Survival was monitored over the next 7 days. In a second study, LPS-injected mice were treated with either DMSO or SAHA as described, and normal (sham) animals served as controls. Lungs were harvested at 4, 6, and 8 hours after LPS injection for analysis of gene expression. In addition, RAW264.7 mouse macrophages were cultured to assess the effects of SAHA post-treatment on LPS-induced inflammation using enzyme-linked immunosorbent assay. All LPS-injected mice that received the vehicle agent alone died within 24 hours, whereas the SAHA-treated animals displayed a significant improvement in 1 week survival (80% vs 0%; P < .001). LPS insult significantly enhanced gene expression of MyD88, tumor necrosis factor (TNF)-alpha and interleukin (IL)-6, and was associated with an increased protein secretion of TNF-alpha and IL-6 into the cell culture medium. In contrast, SAHA treatment significantly attenuated all of these LPS-related alterations. We report for the first time that administration of SAHA (50 mg/kg IP) after a lethal dose of LPS significantly improves long-term survival, and attenuates expression of the proinflammatory mediators TNF-alpha and IL-6. Furthermore, our data suggest that the anti-inflammatory effects of SAHA may be due to downregulation of the MyD88-dependent pathway, and decreased expression of associated proinflammatory genes.

    ABSTRACT: We have previously demonstrated that induction of profound hypothermia improves long-term survival in animal models of complex injuries/lethal hemorrhage. However, the precise mechanisms have not been well defined. The aim of this high-throughput study was to investigate the impact of profound hypothermia on gene expression profiles. Wistar-Kyoto rats underwent 40% blood volume arterial hemorrhage over 10 minutes and were randomized into two groups based on core body temperatures (n = 7 per group): hypothermia (H, 15 degrees C) and normothermia (N, 37 degrees C). Hypothermia was induced by infusing cold isotonic solution using a cardiopulmonary bypass (CPB) setup. After reaching target body temperature, low-flow state (CPB flow rate of 20 mL x kg x min) was maintained for 60 minutes. Hypothermic rats were rewarmed to baseline temperature, and all rats were resuscitated on CPB and monitored for 3 hours. The N group underwent identical CPB management. Sham rats (no hemorrhage and no instrumentation) were used as controls. Blood samples were collected serially, and hepatic tissues were harvested after 3 hours. Affymatrix Rat Gene 1.0 ST Array (27,342 genes, >700,000 probes) was used to determine gene expression profiles (n = 3 per group), which were further analyzed using GeneSpring (Agilent Technologies, Santa Clara, CA) and GenePattern (Broad Institute, Cambridge, MA) programs. Data were further queried using network analysis tools including Gene Ontology, and Ingenuity Pathway Analysis (Ingenuity Systems). Key findings were verified using real-time polymerase chain reaction and Western blots. Induction of hypothermia significantly (p < 0.05) decreased the magnitude of lactic acidosis and increased the survival rates (100% vs. 0% in normothermia group). Five hundred seventy-one of 23,000 genes had altered expression in response to the induction of hypothermia: 382 were up-regulated and 187 were down-regulated. Twelve key pathways were specifically modulated by hypothermia. Interleukin-6, interleukin-10, p38 mitogen-activated protein kinase (MAPK), nuclear factor kappa-light-chain-enhancer of activated B cells, glucocorticoids, and other signaling pathways involved with acute phase reactants were up-regulated. Multiple metabolic pathways were down- regulated. The largest change was in the peroxisome proliferator-activated receptor gamma gene that codes for a transcriptional coactivator, which in turn controls mitochondrial biogenesis, glycerolipid, and other metabolic pathways in the liver. Apoptotic cell death cascades were activated in response to blood loss (H and N groups), but multiple specific anti-apoptotic genes (baculoviral Inhibitor of apoptosis protein repeat-containing 3, BCL3L1, NFKB2) displayed an increased expression specifically in the hypothermia treated animals, suggesting an overall pro-survival phenotype. Profound hypothermia increases survival in a rodent model of hemorrhagic shock. In addition to decreasing tissue oxygen consumption, induction of hypothermia directly alters the expression profiles of key genes, with an overall up-regulation of pro-survival pathways and a down- regulation of metabolic pathways.
