Inhibition of oxidative stress dependent PI3K-δ activation by a selective inhibitor or theophylline provides a novel approach to reversing corticosteroid insensitivity in COPD.

Introduction: Histone deacetylases (HDAC) are frequently deregulated in human cancers and their inhibition allows re-expression of silenced genes. Belinostat is an HDAC inhibitor with in vitro and in vivo activity in multiple malignancies, currently in phase II trials. To date, the pharmacokinetics and metabolism of belinostat have not been adequately characterized. To support an organ dysfunction study and clinical development of belinostat, we developed and validated an LC-MS/MS assay for the sensitive, accurate, and precise quantitation of belinostat and its metabolites belinostat-glucuronide, methylated-belinostat, belinostat amide, 3-ASBA, and belinostat acid in human plasma. Methods: The assay used 50 µL of plasma, [13C6]-belinostat and [D5]-3-ASBA as internal standards and acetonitrile (0.1% TFA) for protein precipitation. A UPLC C18 column was used with a gradient elution from 90:10 to 10:90 water-acetonitrile (0.1% formic acid) over the course of 4 min followed by re-equilibration for ...

In a study published in The EMBO Journal, Vicent and his team show that in the cell lines derived from breast cancer, some 1,000 genes are activated by the steroid hormone progesterone, but another 650 are repressed by it. For the first time, we have described an active repression mechanism involving the progesterone receptor and a repressor complex made up of different proteins, among them the ATPase BRG1, the demethylase KDM1, the histone deacetylases HDAC1/2 and the protein HP1g, adds the researcher. The study focused on processes that take place in the chromatin, the complex of DNA, histones and other proteins found in the nucleus of our cells. Cells need proteins to perform different functions. These are obtained through the information contained in the genes. Cells must control the expression of the genes through transcription factors in charge of reading and interpreting the instructions contained in the DNA to build proteins. However, this is not a simple process. The DNA is packaged ...

Sin3 is an evolutionarily conserved corepressor that exists in different complexes with the histone deacetylases HDAC1 and HDAC2. Sin3-HDAC complexes are believed to deacetylate nucleosomes in the vicinity of Sin3-regulated promoters, resulting in a repressed chromatin structure. We have previously found that a human Sin3-HDAC complex includes HDAC1 and HDAC2, the histone-binding proteins RbAp46 and RbAp48, and two novel polypeptides SAP30 and SAP18. SAP30 is a specific component of Sin3 complexes since it is absent in other HDAC1/2-containing complexes such as NuRD. SAP30 mediates interactions with different polypeptides providing specificity to Sin3 complexes. We have identified p33ING1b, a negative growth regulator involved in the p53 pathway, as a SAP30-associated protein. Two distinct Sin3-p33ING1b-containing complexes were isolated, one of which associates with the subunits of the Brg1-based Swi/Snf chromatin remodeling complex.

Histone deacetylases (HDAC) are key players in epigenetic regulation of gene expression and HDAC inhibitor (HDACi) treatment seems to be a promising anticancer therapy in many human tumours, including soft tissue sarcomas. HR23b has been shown to be a potential biomarker for sensitivity to HDACi therapy in cutaneous T-cell lymphoma and hepatocellular carcinoma. We aimed to evaluate HR23b as a candidate biomarker for HDACi response in sarcomas and gastrointestinal stromal tumours (GIST). Therefore, HR23b expression was analysed comprehensively by western blot in sarcoma and GIST cell lines covering all major clinically relevant subtypes. MTT assay and ApoTox-Glo(TM) Triplex assay were performed after treatment with vorinostat, belinostat, mocetinostat and entinostat. HR23b protein expression was measured under HDACi treatment. Furthermore, HR23b expression levels were immunohistochemically determined in a large set of 523 clinical samples from sarcoma and GIST patients. Western blot analyses ...

In certain respects, this work is consistent with an equally counterintuitive report that HDAC inhibitors can block hypertrophic growth and associated fetal gene induction in cultured cardiomyocytes (15), contrary to the expectation that HDACs suppress a pro-hypertrophic pathway (2). Trichostatin A inhibits both class I and class II HDACs, and growth suppression by HDAC inhibitors need not be specific to Hop and its partners. Nevertheless, the present study is highly noteworthy, from both a mechanistic and a translational point of view. HDAC inhibitors are well tolerated in humans, and clinical trials investigating their efficacy as anticancer agents are currently underway (16). If cardiac hypertrophy is construed to be an adverse adaptation, as supported by the preponderance of evidence (1), and if cardiac function can be preserved even in the face of stress when hypertrophy is blocked (17), the therapeutic merit of HDAC inhibitors in heart failure is potentially important.. The apparent ...

DMellos research, which the NIH has supported for several years, is focused in general on investigating the biological mechanisms underlying neurodegenerative disorders, including Huntingtons disease, Alzheimers, Parkinsons and amyotrophic lateral sclerosis. His recent research results suggest that a key player in promoting neurodegeneration is a protein called histone deacetylase-3 (HDAC3). In preclinical studies, DMellos laboratory and other researchers have found that high levels of this protein are toxic to brain cells.. The new grant will allow DMello and his research team to investigate possible connections between HDAC3 and Huntingtons disease. The genetic mutation responsible for the disorder affects a protein called huntingtin, resulting in a form of the protein that does not function properly. DMello will test the hypothesis that the mutant form of huntingtin inherited by patients with Huntingtons disease activates the neurotoxic effects of HDAC3 that lead to brain cell ...

Little is known about the biol. and structural features that govern the isoform selectivity for class I histone deacetylases (HDACs) over HDAC6. In addn. to that for known inhibitors, like benzamides, psammaplin A, and cyclodepsipeptide-derived thiols, selectivity was also obsd. for naturally occurring cyclopeptide HDAC inhibitors with an aliph. flexible linker and ketonelike zinc-binding group (ZBG). The present study reports that this isoform selectivity is mainly due to the linker and ZBG, as replacement of the cyclopeptide cap region by a simple aniline retained class I HDAC isoform selectivity toward HDAC6 in enzymic assays. The best cyclopeptide-free analogs preserved efficacy against Plasmodium falciparum and cancer cell lines. Mol. modeling provided hypotheses to explain this selectivity and suggests different behaviors of the flexible linker on HDAC1 and HDAC6 pockets, which may influence, on the basis of the strength of the ZBG, its coordination with the zinc ion.

Inhibitors of histone deacetylases are a new class of cancer therapeutics with possibly broad applicability. Combinations of HDAC inhibitors with the kinase inhibitor 1 (Imatinib) in recent studies showed additive and synergistic effects. Here we present a new concept by combining inhibition of protein kinases and HDACs, two independent pharmacological activities, in one synthetic small molecule. In general, the HDAC inhibition profile, the potencies, and the probable binding modes to HDAC1 and HDAC6 were similar as for 6 (SAHA). Inhibition of Abl kinase in biochemical assays was maintained for most compounds, but in general the kinase selectivity profile differed from that of 1 with nearly equipotent inhibition of the wild-type and the Imatinib resistant Abl T(315)I mutant. A potent cellular inhibition of PDGFR and cytotoxicity toward EOL-1 cells, a model for idiopathic hypereosinophilic syndrome (HES), are restored or enhanced for selected analogues (12b, 14b, and 18b). Cytotoxicity was ...

Expression of PD-1 ligands by tumors and interaction with PD-1 expressing T cells in the tumor microenvironment can result in tolerance. Therapies targeting this co-inhibitory axis have proven clinically successful in the treatment of metastatic melanoma, non-small cell lung cancer and other malignancies. Therapeutic agents targeting the epigenetic regulatory family of histone deacetylases (HDACs) have shown clinical success in the treatment of some hematologic malignancies. Beyond direct tumor cell cytotoxicity, HDAC inhibitors have also been shown to alter the immunogenicity and enhance anti-tumor immune responses. Here we show that class I histone deacetylase inhibitors upregulated the expression of PD-L1 and, to a lesser degree, PD-L2 in melanomas. Evaluation of human and murine cell lines and patient tumors treated with a variety of HDAC inhibitors in vitro displayed upregulation of these ligands. This upregulation was robust and durable, with enhanced expression lasting past 96 hours. ...

Histone deacetylase (HDAC) is an emergent anticancer target, and HR23B is a biomarker for response to HDAC inhibitors. We show here that HR23B has impacts on two documented effects of HDAC inhibitors; HDAC inhibitors cause apoptosis in cells expressing high levels of HR23B, whereas in cells with low level expression, HDAC inhibitor treatment is frequently associated with autophagy. The mechanism responsible involves the interaction of HDAC6 with HR23B, which downregulates HR23B and thereby reduces the level of ubiquitinated substrates targeted to the proteasome, ultimately desensitising cells to apoptosis. Significantly, the ability of HDAC6 to downregulate HR23B occurs independently of its deacetylase activity. An analysis of the HDAC6 interactome identified HSP90 as a key effector of HDAC6 on HR23B levels. Our results define a regulatory mechanism that involves the interplay between HR23B and HDAC6 that influences the biological outcome of HDAC inhibitor treatment.

Abstract Thymocyte development is tightly regulated, requiring successful transit of cells through several developmental stages and checkpoints prior to thymic egress. Each checkpoint of thymocyte development, involves induction or repression of a particular set of genes. Disruptions in gene regulation leads to developmental arrest, a failure to generate T cells and deficits in adaptive immunity. Gene expression is coordinated by transcriptional activators, repressors, and chromatin modifiers. In general, histone acetylation promotes gene expression while histone deacetylation leads to repression. We investigated the role of histone deacetylase-3 (HDAC3) in T cell development using CD2-icre conditional knockout (HDAC3- cKO) mice. Although T cells co-express several HDAC family members during development, these other HDAC family members cannot compensate for the loss of HDAC3 as HDAC3-cKO mice have a block in T cell development at the DP stage due to an inability to undergo positive selection. ...

Background: Patients with severe asthma are less sensitive to oral or inhaled corticosteroids. Relative corticosteroid insensitivity has been shown in peripheral blood mononuclear cells and alveolar macrophages in these patients.. Aims and objectives: Determine the response of corticosteroids in airway smooth muscle cells (ASMCs) of severe asthma, in terms of suppression of cytokine-induced chemokine release and mRNA expression, and investigate the underlying mechanisms.. Methods: ASMCs of non-asthmatics (NA; 12), patients with non-severe (NSA; 10) or severe asthma (SA; 10) were pretreated with dexamethasone (Dex; 10-10-10-6 M) followed by stimulation with TNF-α at 10 ng/mL. IL-8 and eotaxin release determined by ELISA; mRNA quantified by RT-PCR. p65 NF-κB recruitment to gene promoters measured by ChIP assay; p38, JNK, and ERK expression measured by Western blot.. Results: Baseline and TNF-α induced eotaxin release and mRNA were higher in NSA, but not SA, compared to NA, while no differences ...

Lipopolysaccharide (LPS) contributes to asthma exacerbations and development of inhaled corticosteroid insensitivity. Complete resistance to systemic corticosteroids is rare and most patients lie on a continuum of steroid responsiveness. The objective of this study was to examine the sensitivity of combined ovalbumin- (Ova) and LPS-induced functional and inflammatory responses to inhaled and systemic corticosteroid in conscious guinea-pigs, to test the hypothesis that the route of administration affects its sensitivity. Guinea-pigs were sensitised to Ova and challenged with inhaled Ova alone or combined with LPS. Airways function was determined by measuring specific airways conductance via whole-body plethysmography. Airways hyperresponsiveness to histamine was determined pre- and 24h post-Ova challenge. Airways inflammation and underlying mechanisms were determined from bronchoalveolar lavage cell counts and lung tissue cytokines. Vehicle or dexamethasone was administered by once-daily ...

Histone deacetylases are important targets for cancer therapeutics, but their regulation is poorly understood. Our data show coordinated transcription of HDAC1 and HDAC2 in lung cancer cell lines, but suggest HDAC2 protein expression is cell-context specific. Through an unbiased siRNA screen we found that BRCA1-associated protein 1 (BAP1) regulates their expression, with HDAC2 reduced and HDAC1 increased in BAP1 depleted cells. BAP1 loss-of-function is increasingly reported in cancers including thoracic malignancies, with frequent mutation in malignant pleural mesothelioma. Endogenous HDAC2 directly correlates with BAP1 across a panel of lung cancer cell lines, and is downregulated in mesothelioma cell lines with genetic BAP1 inactivation. We find that BAP1 regulates HDAC2 by increasing transcript abundance, rather than opposing its ubiquitylation. Importantly, although total cellular HDAC activity is unaffected by transient depletion of HDAC2 or of BAP1 due to HDAC1 compensation, this isoenzyme ...

Histone deacetylation, together with altered acetylation of NF-κB/RelA, encompassing the K310 residue acetylation, occur during brain ischemia. By restoring the normal acetylation condition, we previously reported that sub-threshold doses of resveratrol and entinostat (MS-275), respectively, an activator of the AMP-activated kinase (AMPK)-sirtuin 1 pathway and an inhibitor of class I histone deacetylases (HDACs), synergistically elicited neuroprotection in a mouse model of ischemic stroke. To improve the translational power of this approach, we investigated the efficacy of MS-275 replacement with valproate, the antiepileptic drug also reported to be a class I HDAC blocker. In cortical neurons previously exposed to oxygen glucose deprivation (OGD), valproate elicited neuroprotection at 100 nmol/mL concentration when used alone and at 1 nmol/mL concentration when associated with resveratrol (3 nmol/mL). Resveratrol and valproate restored the acetylation of histone H3 (K9/18), and they reduced the RelA

BACKGROUND. Patients with schizophrenia (SCZ) experience chronic cognitive deficits. Histone deacetylases (HDACs) are enzymes that regulate cognitive circuitry; however, the role of HDACs in cognitive disorders, including SCZ, remains unknown in humans. We previously determined that HDAC2 mRNA levels were lower in dorsolateral prefrontal cortex (DLPFC) tissue from donors with SCZ compared with controls. Here we investigated the relationship between in vivo HDAC expression and cognitive impairment in patients with SCZ and matched healthy controls using [11C]Martinostat positron emission tomography (PET). METHODS. In a case-control study, relative [11C]Martinostat uptake was compared between 14 patients with SCZ or schizoaffective disorder (SCZ/SAD) and 17 controls using hypothesis-driven region-of-interest analysis and unbiased whole brain voxel-wise approaches. Clinical measures, including the MATRICS consensus cognitive battery, were administered. RESULTS. Relative HDAC expression was lower in ...

CYLD is a tumour-suppressor gene that is mutated in a benign skin tumour syndrome called cylindromatosis. The CYLD gene product is a deubiquitinating enzyme that was shown to regulate cell proliferation, cell survival and inflammatory responses, mainly through inhibiting NF-kappaB signalling. Here we show that CYLD controls cell growth and division at the G(1)/S-phase as well as cytokinesis by associating with alpha-tubulin and microtubules through its CAP-Gly domains. Translocation of activated CYLD to the perinuclear region of the cell is achieved by an inhibitory interaction of CYLD with histone deacetylase-6 (HDAC6) leading to an increase in the levels of acetylated alpha-tubulin around the nucleus. This facilitates the interaction of CYLD with Bcl-3, leading to a significant delay in the G(1)-to-S-phase transition. Finally, CYLD also interacts with HDAC6 in the midbody where it regulates the rate of cytokinesis in a deubiquitinase-independent manner. Altogether these results identify a ...

PHILADELPHIA - Drugs that inhibit the activity of enzymes called histone deacetylases (HDACs) are being widely developed for treating cancer and other diseases, with two already on the market. Researchers at the Perelman School of Medicine, University of Pennsylvania, show that a major HDAC still functions in mice even when its enzyme activity is abolished, suggesting that the beneficial effects of HDAC inhibitors may not actually be through inhibiting HDAC activity, and thus warranting the reassessment of the molecular targets of this class of drugs.. The study, appearing online in Molecular Cell this week, was conducted in the laboratory of Mitchell A. Lazar, M.D., Ph.D., director of the Institute for Diabetes, Obesity, and Metabolism. The Lazar lab has been working on HDAC3 for over a decade, focusing on the pivotal role of this enzyme in hormone-mediated regulation of gene expression and metabolism. They previously showed that depletion of HDAC3 in mouse liver upregulates expression of many ...
