Abstract

Fragile X syndrome (FXS) is the leading inherited cause of autism and intellectual disability. Aberrant synaptic translation has been implicated in the etiology of FXS, but most lines of research on therapeutic strategies have targeted protein synthesis indirectly, far upstream of the translation machinery. We sought to perturb p70 ribosomal S6 kinase 1 (S6K1), a key translation initiation and elongation regulator, in FXS model mice. We found that genetic reduction of S6K1 prevented elevated phosphorylation of translational control molecules, exaggerated protein synthesis, enhanced mGluR-dependent long-term depression (LTD), weight gain, and macro-orchidism in FXS model mice. In addition, S6K1 deletion prevented immature dendritic spine morphology and multiple behavioral phenotypes, including social interaction deficits, impaired novel object recognition, and behavioral inflexibility. Our results support the model that dysregulated protein synthesis is the key causal factor in FXS and that restoration of normal translation can stabilize peripheral and neurological function in FXS.

  • Many classic behavioural phenotypes used as preclinical outcome measures are inconsistently observed in Fmr1-knockout mice.

    “many of the other classic behavioural phenotypes used as outcome measures in preclinical studies are inconsistently observed in Fmr1-KO mice (such as open field, rotarod, elevated plus-maze, marble burying, self-grooming and most social paradigms).”
  • Rescue of these behavioural phenotypes has been difficult to consolidate and to use as a guide for clinical studies.

    “As a result, the rescue of these behavioural phenotypes has been difficult to consolidate and to use as a guide for clinical studies30,49,56,64,65.”
  • Core FXS mouse deficits, including protein synthesis, dendritic spine density and morphology, long-term depression, and audiogenic seizures, are consistently rescued by more than ten genetic approaches and multiple drug classes.

    “One striking conclusion of the broad array of preclinical studies is that these core deficits can be consistently rescued by more than ten genetic approaches and multiple classes of pharmacological compounds including mGluR antagonists (MPEP, fenobam, mavoglurant and CTEP), GABA agonists, inhibitors of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA), mechanistic target of rapamycin (mTOR) inhib”

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.
