mTOR signaling: At the crossroads of plasticity, memory and disease

Open access
Hoeffer, Charles A., Klann, Eric·2010·Trends in Neurosciences

Abstract

Mammalian target of rapamycin (mTOR) is a protein kinase involved in translation control and long-lasting synaptic plasticity. mTOR functions as the central component of two multi-protein signaling complexes, mTORC1 and mTORC2, which can be distinguished from each other based on their unique compositions and substrates. Although the majority of evidence linking mTOR function to synaptic plasticity comes from studies utilizing rapamycin, studies in genetically modified mice also suggest that mTOR couples receptors to the translation machinery for establishing long-lasting synaptic changes that are the basis for higher order brain function, including long-term memory. Finally, perturbation of the mTOR signaling cascade appears to be a common pathophysiological feature of human neurological disorders, including mental retardation syndromes and autism spectrum disorders.

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

  • mTORC1-mediated signaling is required for translation of a subset of dendritic proteins.

    “The mammalian target of rapamycin complex 1 (mTORC1)-mediated signaling pathway is required for the translation of a subset of dendritic proteins12”
  • mTORC1 is implicated in synaptic plasticity and memory processes.

    “and is implicated in synaptic plasticity12, 13, as well as in memory processes12.”
  • mTOR signaling contributes to protein synthesis required for neuronal survival, development, synaptic plasticity, learning, and memory.

    “mTOR signaling, however, contributes to protein synthesis required for neuronal survival, development, synaptic plasticity, learning, and memory (Hoeffer and Klann, 2010)”

    From Loss of mTOR-Dependent Macroautophagy Causes Autistic-like Synaptic Pruning Deficits (2014) · cites this paper as Hoeffer and Klann, 2010

  • mTOR is a serine/threonine kinase that regulates neurogenesis, dendritic spine growth, protein translation initiation, and protein synthesis via phosphorylation of p70S6 kinase and repression of 4E binding proteins.

    “Mechanistic target of rapamycin (mTOR) is a serine/threonine kinase that regulates neurogenesis, dendritic spine growth, protein translation initiation, and protein synthesis via a phosphorylation of p70S6 kinase and repression of 4E binding proteins (4EBP 173–175).”

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.
