spinal cord injury (sci)-induced systemic inflammatory response affects multiple organs outside the spi­nal cord. treatment options for such complications are lacking. valproic acid (vpa) is a histone deacetylase inhibitor, acting directly at the level of gene transcription by inhibiting histone deacetylation and making transcription sites more accessible. acetylation of histones is critical to...

Histone acetylation is important for regulating chromatin structure and gene expression. Three classes of mammalian histone deacetylases have been identified. Among class II, there are five known members, namely HDAC4, HDAC5, HDAC6, HDAC7 and HDAC9. Here we describe the identification and characterization of a novel class II member termed HDAC10. It is a 669 residue polypeptide with a bipartite...

The tight interaction between genomic DNA and histones, which normally represses gene transcription, can be relaxed by histone acetylation. This loosening of the DNA-histone complex is important for selective gene activation during stem cell differentiation. Histone acetylation may be increased through the application of histone deacetylase inhibitors at the early stages of differentiation to m...

Members of the Mad family of bHLH-Zip proteins heterodimerize with Max to repress transcription in a sequence-specific manner. Transcriptional repression by Mad:Max heterodimers is mediated by ternary complex formation with either of the corepressors mSin3A or mSin3B. We report here that mSin3A is an in vivo component of large, heterogeneous multiprotein complexes and is tightly and specificall...

Hybrid polar compounds (HPCs) have been synthesized that induce terminal differentiation and/or apoptosis in various transformed cells. We have previously reported on the development of the second-generation HPCs suberoylanilide hydroxamic acid (SAHA) and m-carboxycinnamic acid bishydroxamide (CBHA) that are 2,000-fold more potent inducers on a molar basis than the prototype HPC hexamethylene b...

Histone deacetylase inhibitors represent a new class of anticancer therapeutics and the expectation is that they will be most effective when used in combination with conventional cancer therapies, such as the anthracycline, doxorubicin. The dose-limiting side effect of doxorubicin is severe cardiotoxicity and evaluation of the effects of combinations of the anthracycline with histone deacetylas...

neurodegenerative disorders such as huntingtons disease, alzheimers disease, parkinsons disease, amyotrophic lateral sclerosis, spinal muscular atrophy, friedreichs ataxia, and others are multi-factorial illnesses in which many pathways (still poorly understood) act serially and in parallel to give a determined pathologic phenotype. thus, presently there are no effective cures for these disease...

We report the development of a potent, selective histone deacetylase 6 (HDAC6) inhibitor. This HDAC6 inhibitor blocks growth of normal and transformed cells but does not induce death of normal cells. The HDAC6 inhibitor alone is as effective as paclitaxel in anticancer activity in tumor-bearing mice.

BACKGROUND/AIMS Our previous study has demonstrated that down-regulation of miR-376a might contribute to the development of hepatocellular carcinoma (HCC), but the mechanism underlying this down-regulation remains obscure. METHODS/RESULTS histone deacetylase (HDAC) inhibitor increased the level of miR-376a in L02 and Huh7 cells by up-regulating the acetylation level of histone 3 at the Matern...
