Abstract

The transcriptional activity of the androgen receptor (AR) is regulated by both ligand binding and post-translational modifications, including acetylation and small ubiquitin-like modifier (SUMO)ylation. Histone deacetylases (HDACs) are known to catalyze the removal of acetyl groups from both histones and non-histone proteins. In this study, we report that HDAC4 binds to and inhibits the activity of the AR. This inhibition was found to depend on the SUMOylation, instead of deacetylation, of the AR. Consistently, HDAC4 increases the level of AR SUMOylation in both whole-cell and cell-free assay systems, raising the possibility that the deacetylase may act as an E3 ligase for AR SUMOylation. Knock down of HDAC4 increases the activity of endogenous AR and androgen induction of prostate-specific antigen expression and prostate cancer cell growth, which is associated with decreased SUMOylation of the receptor. Overall, the studies identify HDAC4 as a positive regulator for AR SUMOylation, revealing a deacetylase-independent mechanism of HDAC action in prostate cancer cells.

  • HDAC4 belongs to the SUMO E3 ligase family and can directly SUMOylate IκBα, AR, LXRα, and MEF2.

    “Additionally, HDAC4 belongs to the SUMO E3 ligase family and can directly SUMOylate IκBα, AR, LXRα, and MEF217–20.”

    The Results section reports that HDAC4 increases AR SUMOylation. The Discussion describes HDAC4 as a *possible* SUMO E3 ligase, notes reports concerning MEF2 and LXR, and says AR SUMOylation might instead be enhanced through other E3 enzymes. It does not establish direct SUMOylation of all four named proteins, and the searched passages do not address IκBα. Page numbers were not supplied. (LLM, conf=0.88)

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.
