Abstract

Fragile X syndrome (FXS) is the most frequent inherited form of intellectual disability and autism spectrum disorder. Loss of the fragile X mental retardation protein, FMRP, engenders molecular, behavioral, and cognitive deficits in FXS patients. Experiments using different animal models advanced our knowledge of the pathophysiology of FXS and led to the discovery of many targets for drug treatments. In this review, we discuss the potential of metformin, an antidiabetic drug approved by the US Food and Drug Administration, to correct core symptoms of FXS and other neurological disorders in humans. We summarize its mechanisms of action in different animal and cellular models and human diseases.

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

  • Animal studies in FXS have demonstrated a hyperactive insulin receptor and up-regulation of mTORC1 and MAPK/ERK signaling pathways, as well as elevation of MMP-9 levels in the absence of FMRP.

    “Animal studies in FXS have demonstrated a hyperactive insulin receptor and up-regulation of the mammalian target of rapamycin complex 1 (mTORC1) and mitogen-activated protein kinase/extracellular signal-related kinases (MAPK/ERK) signaling pathways, as well as elevation of MMP-9 levels in the absence of FMRP, the protein produced by the FMR1 gene [106–108].”

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.
