HDAC3 deacetylates histones in vitro and has been purified as a catalytic subunit of SMRT-NCoR containing nuclear complexes, which mediate nuclear hormone receptor-dependent transcriptional repression (23, 25, 26). 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. The work presented by Jiang and colleagues addresses how somatic mutations in CREBBP disable acetylation and cause unopposed deacetylation by BCL6/SMRT/HDAC3 Tasquinimod is an orally active antiangiogenic drug that is currently in phase III clinical trials for the treatment of castration-resistant prostate cancer.

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 As expected, AKT phosphorylation was elevated by PTEN knockdown in PTEN‐positive 22Rv1 prostate cancer cells, but PTEN loss‐enhanced AKT phosphorylation was mitigated by HDAC3 co‐knockdown (Fig 6A). Knockdown of HDAC3 in PTEN‐negative C4‐2 cells decreased cell growth in both 2‐dimension (2D) and 3D cultures (Fig EV3A–E). Nov 06, 2019 · HDAC3 has been previously identified as an important epigenetic regulator of inflammatory gene transcription.
