Hdac3 is essential for the maintenance of chromatin structure and genome stability

Open access

Abstract

Hdac3 is essential for efficient DNA replication and DNA damage control. Deletion of Hdac3 impaired DNA repair and greatly reduced chromatin compaction and heterochromatin content. These defects corresponded to increases in histone H3K9,K14ac; H4K5ac; and H4K12ac in late S phase of the cell cycle, and histone deposition marks were retained in quiescent Hdac3-null cells. Liver-specific deletion of Hdac3 culminated in hepatocellular carcinoma. Whereas HDAC3 expression was downregulated in only a small number of human liver cancers, the mRNA levels of the HDAC3 cofactor NCOR1 were reduced in one-third of these cases. siRNA targeting of NCOR1 and SMRT (NCOR2) increased H4K5ac and caused DNA damage, indicating that the HDAC3/NCOR/SMRT axis is critical for maintaining chromatin structure and genomic stability.

  • HDAC3 is required for genome maintenance and DNA replication in hematopoietic cells.

    “HDAC3 was found to be required for genome maintenance and DNA replication in hematopoietic cells (27, 28); therefore, HDAC3 inhibition is suspected to be responsible for bone marrow toxicity seen with nonselective HDAC inhibitors (29).”

    From TNG260 Is a Small-Molecule CoREST Inhibitor That Sensitizes <i>STK11</i> -Mutant Tumors to Anti–PD-1 Immunotherapy (2025) · cites this paper as [28]

    The Results (‘Hdac3 is required for genomic stability’; page not provided) report increased chromosome breaks and gaps after Hdac3 deletion in mouse embryonic fibroblasts, and the paper states that Hdac3 is essential for efficient DNA replication. The cited copy does not establish those requirements in hematopoietic cells; its Discussion mentions bone-marrow cells only when considering possible effects of HDAC inhibitors. (LLM, conf=0.88)

  • HDAC3 affects genome instability.

    “Preliminary studies have shown that HDAC3 affects genome instability.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
