Abstract

Mice with a mutation in the Clock gene (ClockΔ19) have been identified as a model of mania; however, the mechanisms that underlie this phenotype, and the changes in the brain that are necessary for lithium's effectiveness on these mice remain unclear. Here, we find that cholecystokinin (Cck) is a direct transcriptional target of CLOCK and levels of Cck are reduced in the ventral tegmental area (VTA) of ClockΔ19 mice. Selective knockdown of Cck expression via RNA interference in the VTA of wild-type mice produces a manic-like phenotype. Moreover, chronic treatment with lithium restores Cck expression to near wild-type and this increase is necessary for the therapeutic actions of lithium. The decrease in Cck expression in the ClockΔ19 mice appears to be due to a lack of interaction with the histone methyltransferase, MLL1, resulting in decreased histone H3K4me3 and gene transcription, an effect reversed by lithium. Human postmortem tissue from bipolar subjects reveals a similar increase in Cck expression in the VTA with mood stabilizer treatment. These studies identify a key role for Cck in the development and treatment of mania, and describe some of the molecular mechanisms by which lithium may act as an effective antimanic agent.

  • Clock regulates cholecystokinin (CCK) expression in the ventral tegmental area (VTA), and the Δ19 mutation in the Clock gene is sufficient to induce manic-like behaviors.

    “Notably, clock regulates cholecystokinin (CCK) expression in the ventral tegmental area (VTA) and Δ19 mutation in the Clock gene is sufficient to induce manic-like behaviors102.”

    From Circadian rhythm disruption and mental health (2020) · cites this paper as [102]

  • Circadian genes in brain regions outside the SCN contribute locally to the control of neuronal metabolism, neurotransmitter synthesis and activity, and disruption of these functions might contribute to brain disorders.

    “circadian genes in other brain regions outside of this central pace-maker also contribute locally to the control of neuronal metabolism, neurotransmitter synthesis and activity, and the disruption of these functions might contribute to brain disorders264,304–315”

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.
