Abstract

Monoamine oxidase A (MAO-A) is an enzyme that regulates the levels of monoamine neurotransmitters, such as serotonin, noradrenaline and dopamine and it has been used as a therapeutic target for depression. However, MAO-A inhibitors, which directly acts on MAO-A protein, have limited use due to their adverse effects. microRNAs (miRNAs) are 18-22 nucleotide long, small non-coding RNAs, which have recently emerged as regulators of protein levels that could potentially be new therapeutic targets for psychiatric disorders. This review article aims to discuss the current status of the treatment for depression with MAO-A inhibitors and the regulatory factors of MAO-A. Further, the review also proposes possible regulatory mechanisms of MAO-A by miRNAs, which leads to better understanding of the pathology of depressive disorders and their potential use as therapeutic agents.

  • miR-142, miR-34a, and miR-34c indirectly regulate MAO-A, potentially impacting monoamine neurotransmitters.

    From Epigenetic regulation in major depression and other stress-related disorders: molecular mechanisms, clinical relevance and therapeutic potential (2023) · cites this paper as [284]

    The figure caption presents a proposed indirect pathway: miR-142, miR-34a and miR-34c target SIRT1, which activates MAO-A expression. The miR-142 section reports experimental evidence for that pathway, but the miR-34 Family section does not establish that miR-34a or miR-34c regulates MAO-A; it frames the connection as a possibility. The Introduction supports the potential relevance to monoamine neurotransmitters by reporting that MAO-A inhibition elevates brain serotonin. (LLM, conf=0.84)

  • miRNA-mediated disturbance of neurotransmitters including glutamate, dopamine, serotonin, and norepinephrine can lead to neuronal damage and loss of trophic effects and thereby potentially contribute to the pathogenesis of depression.

    The Abstract and Conclusion link miRNAs, MAO-A regulation, and depression; the Abstract identifies serotonin, noradrenaline, and dopamine as neurotransmitters regulated by MAO-A. The paper does not establish the claimed chain from miRNA-mediated disturbance of those transmitters and glutamate to neuronal damage, loss of trophic effects, and depression. No page numbers are available in our copy. (LLM, conf=0.85)

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.
