8/13/2007 HDAC3 is highly expressed in the dorsal hippocampus, and HDAC3floχ/floχmice infused with AAV-Cre showed a complete focal deletion of HDAC3 primarily in the CA1 of the dorsal hippocampus (Fig. 2A). In the area of the HDAC3 deletion, we observed a decrease in HDAC4, but not HDAC2, immunoreactivity (McQuown et al., 2011). C-terminally FLAG-tagged HDAC3 and Myc-tagged DAD were co-expressed in HEK 293 cells as described above. Cells were lysed in 50 mM Tris pH 7.5, 50 mM potassium acetate, 5 % v/v glycerol, 0.3 % v/v Triton X-100, Roche complete protease inhibitor.

These initial observations and follow-up studies have firmly established HDAC3 as a transcriptional co-repressor . NIH-PA Author Manuscript Hdac3, a class I HDAC, associates with the nuclear hormone co-repressors (NCoR and SMRT) (Codina et al., 2005) and is generally thought of as a locus-specific co-repressor that is recruited to promoters to repress genes regulated by nuclear hormone receptors and other transcription factors (Jones and Shi, 2003). The HDAC3 (class I HDAC) tends to have an expression profile similar to those of HDAC1, HDAC2, and HAT1, whereas the HDAC7 (class II HDAC) and GCN5 (type A HAT) profiles were different from those three. Summary: The cellular phenotype of B-cell lymphomas arising from B cells undergoing germinal center reactions, such as follicular lymphoma and diffuse large B-cell lymphoma, is strongly shaped by mutations in chromatin-modifying genes.

HDAC3 exists in a large (~270 kDa) multiprotein co-repressor complex containing the nuclear receptor corepressor (NCOR) and/or its homolog silencing mediator of retinoic and thyroid receptors (SMRT) (reviewed by Karagianni and Wong, 2007). Non-targeting control or HDAC3 siRNA (Dharmacon, Lafayette, CO) was combined with Lipofectamine 2000 reagent in OptiMEM at a 100 nM final concentration. Seventy-two hours post-transfection RNA was isolated and subjected to reverse-transcription and quantitative real-time PCR. Core subunits are histone deacetylase 3 (HDAC3), nuclear receptor co-repressor (NCOR, also known as NCOR1), and silencing mediator of retinoic acid and thyroid hormone receptor (SMRT, also known as NCOR2). Thus, the complex is usually referred to as the HDAC3 complex, the NCOR/SMRT complex, or simply as NR-co-repressor complex. Hdac3, a class I HDAC, associates with the nuclear hormone co-repressors (NCoR and SMRT) (Codina et al., 2005) and is generally thought of as a locus-specific co-repressor that is recruited to promoters to repress genes regulated by nuclear hormone receptors and other transcription factors (Jones and Shi, 2003).

FOXO3 binding to chromatin was then assessed at the promoters of Arrdc2 , Dusp4 , Klf10 , Tle1 , and Bdnf in hippocampal CA1 of Hdac3 cKO mice by ChIP qPCR, and we found that FOXO3 differentially expressed tolerizable TFs with the HDAC3-bound TFs in mouse BMDMs as obtained from GSE106701 samples GSM2845618 and GSM2845619. The x-axis represents the log HDAC3 is the only member of the class I/II HDAC family that regulates AKT phosphorylation and its expression correlates with AKT phosphorylation in prostate cancer patient specimens. HDAC3 regulation of AKT phosphorylation is mediated by deacetylation of K14 and K20 residues on AKT and the function of HDAC3 in the cytoplasm. HDAC7 possesses little intrinsic deacetylase activity and therefore requires association with the class I HDAC, HDAC3 in order to suppress gene expression.

It has been demonstrated through crystal structures of the human HDAC7 that the catalytic domain of HDAC7 has an additional class IIa HDAC-specific zinc binding motif adjacent to the active 4/24/2012 Histone deacetylase 3 (HDAC3) is an epigenome-modifying enzyme that is required for normal mouse development and tissue-specific functions. In vitro, HDAC3 protein itself has minimal enzyme activity, but gains its histone deacetylation function from stable association with the conserved deacetylase activation domain (DAD) contained in nuclear receptor corepressors NCOR1 and SMRT. Arrows point to the co‐localization of AKT and HDAC3 proteins in the plasma membrane. Approximately 80% of LNCaP cells and 85% of C4‐2 cells showed the co‐localization of these two proteins on plasma membrane.
