Abstract

Major depression is a highly complex disabling psychiatric disorder affecting millions of people worldwide. Despite the availability of several classes of antidepressants, a substantial percentage of patients are unresponsive to these medications. A better understanding of the neurobiology of depression and the mechanisms underlying antidepressant response is thus critically needed. We previously reported that mice lacking CREB-regulated transcription coactivator 1 (CRTC1) exhibit a depressive-like phenotype and a blunted antidepressant response to the selective serotonin reuptake inhibitor fluoxetine. In this study, we similarly show that Crtc1(-/-) mice are resistant to the antidepressant effect of chronic desipramine in a behavioral despair paradigm. Supporting the blunted response to this tricyclic antidepressant, we found that desipramine does not significantly increase the expression of Bdnf and Nr4a1-3 in the hippocampus and prefrontal cortex of Crtc1(-/-) mice. Epigenetic regulation of neuroplasticity gene expression has been associated with depression and antidepressant response, and histone deacetylase (HDAC) inhibitors have been shown to have antidepressant-like properties. Here, we show that unlike conventional antidepressants, chronic systemic administration of the HDAC inhibitor SAHA partially rescues the depressive-like behavior of Crtc1(-/-) mice. This behavioral effect is accompanied by an increased expression of Bdnf, but not Nr4a1-3, in the prefrontal cortex of these mice, suggesting that this epigenetic intervention restores the expression of a subset of genes by acting downstream of CRTC1. These findings suggest that CRTC1 alterations may be associated with treatment-resistant depression, and support the interesting possibility that targeting HDACs may be a useful therapeutic strategy in antidepressant development.

  • In genetically susceptible models of treatment-resistant depression, SAHA inhibits HDAC2, restores histone acetylation and BDNF levels, and reverses antidepressant non-responsiveness.

    “In genetically susceptible models of treatment-resistant depression, SAHA inhibits HDAC2, restores histone acetylation and BDNF levels, and reverses antidepressant non-responsiveness (Meylan et al., 2016; Vialou et al., 2013).”

    From Histone modifications and depression: epigenetic mechanisms, therapeutic targets, and translational outlook (2026) · cites this paper as Meylan et al., 2016

    The Results (pages unavailable) show that SAHA increased histone acetylation and restored prefrontal-cortex Bdnf mRNA expression in Crtc1-deficient mice; the Discussion reports a partial improvement in depressive-like behavior. The paper describes inhibition of class I and II HDACs, not HDAC2-specific inhibition, and found no baseline histone-acetylation deficit to restore. It did not show restored BDNF protein levels or reversal of the mice’s non-responsiveness to conventional antidepressants. (LLM, conf=0.90)

  • Suberoylanilide hydroxamic acid has a rapid antidepressant action and may be effective for depressive-like behaviors in mice that are resistant to conventional treatments.

    “other reports have also shown that SAHA has a rapid antidepressant action 66 and that SAHA treatment may be effective for depressive-like behaviors in mice that are resistant to conventional treatments.”

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.
