Here, we define the landscape and dynamics of active regulatory DNA in cutaneous T cell lymphoma (CTCL) by ATAC-seq. Analysis of 111 human CTCL and control samples revealed extensive chromatin signatures that distinguished leukemic, host, and normal CD4+ T cells. We identify three dominant patterns of transcription factor (TF) activation that drive leukemia regulomes, as well as TF deactivation...

Histone/protein deacetylases play multiple roles in regulating gene expression and protein activation and stability. Their deregulation during cancer initiation and progression cause resistance to therapy. Here, we review the role of histone deacetylases (HDACs) and the NAD+ dependent sirtuins (SIRTs) in the DNA damage response (DDR). These lysine deacetylases contribute to DNA repair by base e...

Abstract Using two H3K27M-DMG treatment-naive preclinical models (PBT22 and PBT29), we detected a 20-fold differential response to the histone deacetylase inhibitor, Quisinostat. PBT-22 harbors mutations in H3F3A, TP53, ASXL2, while PBT-29 has PIK3CA FGFR1. Acetylation deacetylation of wtH3 alter chromatin structure as part normal regulation gene expression. The methionine substitution for Lysi...

A combination of demethylating agents and histone deacetylase inhibitors (HDACi) has been proposed as a novel therapy in leukemia and myelodysplasia. In HL-60 cells azacytidine (AZA) and Metacept-1 (MCT-1), a novel HDACi augmented inhibition of cell growth and increased apoptosis. In identifying a molecular mechanism responsible for these effects MCT-1 alone and in combination with AZA induced ...

Previous studies have shown that histone deacetylase inhibitors (HDACis) can kill cancer cells. In addition, HDACis can induce mitotic catastrophe in cancer cells due to insufficient localization of chromosomal passenger complex (CPC) to the centromere. However, the mechanisms behind these phenomena remain unclear. In this study, we found that a HDACi, FK228, affected multiple epigenetic modifi...

Although combined antiretroviral therapy (cART) successfully decreases plasma viremia to undetectable levels, the complete eradication of human immunodeficiency virus type 1 (HIV-1) remains impractical because of the existence of a viral reservoir, mainly in resting memory CD4(+) T cells. Various cytokines, protein kinase C activators, and histone deacetylase inhibitors (HDACi) have been used a...

Post-partum uterine disorders and reproductive tract infections cause ovarian dysfunction and infertility. Histone deacetylases (HDACs) prevent the relaxation of chromatin, and positively or negatively regulate transcription. Hence, HDACs play a pivotal role in altering the gene expression that impact different signalling pathways underling ovarian dysfunction. Thus, HDAC inhibitors (HDACi) may...

Although many viral particles can enter a single cell, the number of viral genomes per cell that establish infection is limited. However, mechanisms underlying this restriction were not explored in depth. For herpesviruses, one of the possible mechanisms suggested is chromatinization and silencing of the incoming genomes. To test this hypothesis, we followed infection with three herpes simplex ...

inhibitors would be a good strategy. Studies are required to decipher the impact of chemotherapies on the immunogenicity of remaining AML cells. This strategy will have to be carefully examined because ongoing clinical studies have embarked novel chemotherapy combinations together with the methyltransferase inhibitor decitabine and HDACi that display complex functional consequences on AML funct...

Despite prominent role of radiotherapy in lung cancer management, there is an urgent need for strategies increasing therapeutic efficacy. Reversible epigenetic changes are promising targets for combination strategies using HDAC inhibitors (HDACi).Here we evaluated on two NSCLC cell lines, the antitumor effect of abexinostat, a novel pan HDACi combined with irradiation in vitro in normoxia and h...
