Abstract

In neurons, dynamic changes in the subcellular localization of histone deacetylases (HDACs) are thought to contribute to signal-regulated gene expression. Here we show that in mouse hippocampal neurons, synaptic activity-dependent nucleo-cytoplasmic shuttling is a common feature of all members of class IIa HDACs, which distinguishes them from other classes of HDACs. Nuclear calcium, a key regulator in neuronal gene expression, is required for the nuclear export of a subset of class IIa HDACs. We found that inhibition of nuclear calcium signaling using CaMBP4 or increasing the nuclear calcium buffering capacity by means of expression of a nuclear targeted version of parvalbumin (PV.NLS-mC) led to a build-up of HDAC4 and HDAC5 in the cell nucleus, which in the case of PV.NLS-mC can be reversed by nuclear calcium transients triggered by bursts of action potential firing. A similar nuclear accumulation of HDAC4 and HDAC5 was observed in vivo in the mouse hippocampus following stereotaxic delivery of recombinant adeno-associated viruses expressing either CaMBP4 or PV.NLS-mC. The modulation of HDAC4 activity either by RNA interference-mediated reduction of HDAC4 protein levels or by expression of a constitutively nuclear localized mutant of HDAC4 leads to changes in the mRNA levels of several nuclear calcium-regulated genes with known functions in acquired neuroprotection (atf3, serpinb2), memory consolidation (homer1, arc), and the development of chronic pain (ptgs2, c1qc). These results identify nuclear calcium as a regulator of nuclear export of HDAC4 and HDAC5. The reduction of nuclear localized HDACs represents a novel transcription-promoting pathway stimulated by nuclear calcium.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Cytoplasmic localization of HDAC4 is maintained by phosphorylation, suppressing MEF2 binding, whereas dephosphorylation by calcineurin allows nuclear translocation.

    “Cytoplasmic localization of HDAC4 is maintained by HDAC phosphorylation, suppressing the binding of the transcription factor MEF2,141 whereas HDAC4 dephosphorylation by calcineurin allows nuclear translocation.142”

    From Epigenetic regulation in major depression and other stress-related disorders: molecular mechanisms, clinical relevance and therapeutic potential (2023) · cites this paper as [141]

    Citation 142 attaches to the clause about HDAC4 dephosphorylation and nuclear translocation. The Discussion (page unavailable) says cytoplasmic dephosphorylation unmasks HDAC4’s nuclear localization signal and initiates nuclear import, but names PP2A as a phosphatase that can catalyze it; it does not establish calcineurin’s role. (LLM, conf=0.86)

  • Phosphorylation of HDAC4 by Ca2+/calmodulin-dependent protein kinases maintains cytoplasmic localization of HDAC4, leads to its nuclear export, and suppresses the transcription factor MEF2.

    “Phosphorylation of HDAC4 by Ca 2+ /calmodulin-dependent protein kinases (CAMK) maintains cytoplasmic localization of HDAC4, leads to its nuclear export, 55,56 and suppresses the transcription factor MEF2.”

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.
