The persistence of transcriptionally silent but replication-competent HIV-1 reservoirs in Highly Active Anti-Retroviral Therapy (HAART)-treated infected individuals, represents a major hurdle to virus eradication. Activation of HIV-1 gene expression in these cells together with an efficient HAART has been proposed as an adjuvant therapy aimed at decreasing the pool of latent viral reservoirs. U...
Oocyte maturation and embryonic development are sensitive to DNA damage. Compared with somatic cells or oocytes, little is known about the response to DNA damage in early preimplantation embryos. In this study, we examined DNA damage checkpoints and DNA repair mechanisms in parthenogenetic preimplantation porcine embryos. We found that most of the etoposide-treated embryos showed delay in cleav...
Interactions between bortezomib and romidepsin and belinostat in chronic lymphocytic leukemia cells.
PURPOSE The goal of this study was to characterize interactions between the proteasome inhibitor bortezomib and the histone deacetylase (HDAC) inhibitors (HDACI) romidepsin or belinostat in chronic lymphocytic leukemia (CLL) cells. EXPERIMENTAL DESIGN Primary and cultured (JVM-3 and MEC-2) CLL cells were exposed to agents alone or in combination, after which cell death was determined by 7-ami...
INTRODUCTION Medulloblastoma (MB) is the most frequent malignant brain tumor in children. Four subgroups with distinct genetic, epigenetic and clinical characteristics have been identified. Survival remains particularly poor in patients with Group 3 tumors harbouring a MYC amplification. We herein explore the molecular mechanisms and translational implications of class I histone deacetylase (HD...
Download pose: Histone deacetylase inhibitors (HDACi) are targeted anticancer agents with a well-documenility to act synergistically with cytotoxic agents. We recently showed that the HDACi valproic acid izes osteosarcoma cells to doxorubicin in vitro and in vivo. As there are no published reports on the l utility of HDACi in dogs with spontaneous cancers, we sought to determine a safe and biol...
Histone deacetylase inhibitors (HDACi) induce tumour cell cycle arrest and/or apoptosis, and some of them are currently used in cancer therapy. Recently, we described a series of powerful HDACi characterized by a 1,4-benzodiazepine (BDZ) ring hybridized with a linear alkyl chain bearing a hydroxamate function as Zn(++)--chelating group. Here, we explored the anti-leukaemic properties of three n...
Histone acetylation regulates higher-order chromatin structure and function and is critical for the control of gene expression. Histone deacetylase inhibitors (HDACi) are currently under investigation as novel cancer therapeutic drugs. Here, we show that female germ cells are extremely susceptible to chromatin changes induced by HDACi. Our results indicate that exposure to trichostatin A (TSA) ...
OBJECTIVES Non-selective histone deacetylase (HDAC) inhibitors (HDACi) have demonstrated anti-inflammatory properties in both in vitro and in vivo models of rheumatoid arthritis (RA). Here, we investigated the potential contribution of specific class I and class IIb HDACs to inflammatory gene expression in RA fibroblast-like synoviocytes (FLS). METHODS RA FLS were incubated with pan-HDACi (IT...
Histone epigenetic modifications are one of the frequently observed epigenetic alterations in leukemic cells. To efficiently identify histone acetylation status of a number of gene promoters in chronic lymphocytic leukemia (CLL) specimens, we performed a combination of chromatin immunoprecipitation (ChIP) and PCR array. ChIP by an antipan acetylated H4 histone antibody was followed by a PCR amp...
