Abstract

Many neuropsychiatric symptoms of fragile X syndrome (FXS) are believed to be a consequence of altered regulation of protein synthesis at synapses. We discovered that lovastatin, a drug that is widely prescribed for the treatment of high cholesterol, can correct excess hippocampal protein synthesis in the mouse model of FXS and can prevent one of the robust functional consequences of increased protein synthesis in FXS, epileptogenesis. These data suggest that lovastatin is potentially disease modifying and could be a viable prophylactic treatment for epileptogenesis in FXS.

  • Treatment with lovastatin dampens neuronal hyperexcitability in the brain of Fmr1 KO mice and rescues part of the mouse FXS phenotype.

    “Treatment with lovastatin, an inhibitor of 3-hydroxy-3-methylglutarylcoenzyme A (HMG-CoA) reductase which regulates the early irreversible and rate-limiting step in the biosynthesis of cholesterol, dampens neuronal hyperexcitability in the brain of FXS mouse model, Fmr1 KO mice, and rescues part of the mouse FXS phenotype14.”
  • Statin treatment might improve behavioral outcomes in FXS children and lovastatin has beneficial effects on the phenotype of Fmr1 KO mice.

    “Statin treatment might improve behavioral outcomes in FXS children16,17 and lovastatin has beneficial effects on the phenotype of Fmr1 KO mice14.”
  • Microglia recycle neuronal cholesterol during dendrite pruning.

    “Furthermore, microglia, which function as brain macrophages, recycle neuronal cholesterol during dendrite pruning39, and replacing mutant with wild type microglia via bone marrow transfer ameliorated RTT symptoms in Mecp2 null mice13.”

    From A suppressor screen in Mecp2 mutant mice implicates cholesterol metabolism in Rett syndrome (2013) · cites this paper as [39]

    The Results passage on hippocampal-slice epileptogenesis and the Discussion passage on fragile X symptoms address lovastatin, protein synthesis, and seizures, not microglia or cholesterol recycling. Searches for microglia, neuronal cholesterol, and dendrite pruning found no passage in our copy addressing the attributed claim. (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.
