Abstract

Post-transcriptional modifications of RNA, such as RNA methylation, can epigenetically regulate behavior, for instance learning and memory. However, it is unclear whether RNA methylation plays a critical role in the pathophysiology of major depression disorder (MDD). Here, we report that expression of the fat mass and obesity associated gene (FTO), an RNA demethylase, is downregulated in the hippocampus of patients with MDD and mouse models of depression. Suppressing Fto expression in the mouse hippocampus results in depression-like behaviors in adult mice, whereas overexpression of FTO expression leads to rescue of the depression-like phenotype. Epitranscriptomic profiling of N6-methyladenosine (m 6 A) RNA methylation in the hippocampus of Fto knockdown (KD), Fto knockout (cKO), and FTO-overexpressing (OE) mice allows us to identify adrenoceptor beta 2 ( Adrb2 ) mRNA as a target of FTO. ADRB2 stimulation rescues the depression-like behaviors in mice and spine loss induced by hippocampal Fto deficiency, possibly via the modulation of hippocampal SIRT1 expression by c-MYC. Our findings suggest that FTO is a regulator of a mechanism underlying depression-like behavior in mice.

  • Lack of the FTO gene impacts anxiety-depression-like behavior in mice.

    “Lack of the FTO gene impacts anxiety-depression-like behavior in mice.360”

    From Epigenetic regulation in major depression and other stress-related disorders: molecular mechanisms, clinical relevance and therapeutic potential (2023) · cites this paper as [360]

    The Results section, “FTO mediates depression-like behaviors in the hippocampus,” reports that hippocampal Fto knockdown or knockout induced depression-like behaviors in mice. The same section explicitly reports no significant change in anxiety-like behaviors, so the anxiety part of the claim is not supported. (LLM, conf=0.90)

  • The m6A demethylase gene ALKBH5 variant rs12936694 showed an allelic association and genotypic association with MDD.

    “The m6A demethylase gene ALKBH5 variant rs12936694 showed an allelic association and genotypic association with MDD.360,363”

    From Epigenetic regulation in major depression and other stress-related disorders: molecular mechanisms, clinical relevance and therapeutic potential (2023) · cites this paper as [360]

    The Results section reports lower ALKBH5 expression in blood from patients with MDD, not an association between an ALKBH5 variant and MDD. Searches for rs12936694 and for allelic or genotypic associations found no passage addressing the claimed variant; the indexed passages provide no page numbers. (LLM, conf=0.76)

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.
