Abstract

In addition to neurological deficits, Huntington's disease (HD) patients and transgenic mice expressing mutant human huntingtin exhibit reduced levels of brain-derived neurotrophic factor, hyperglycemia, and tissue wasting. We show that the progression of neuropathological (formation of huntingtin inclusions and apoptotic protease activation), behavioral (motor dysfunction), and metabolic (glucose intolerance and tissue wasting) abnormalities in huntingtin mutant mice, an animal model of HD, are retarded when the mice are maintained on a dietary restriction (DR) feeding regimen resulting in an extension of their life span. DR increases levels of brain-derived neurotrophic factor and the protein chaperone heat-shock protein-70 in the striatum and cortex, which are depleted in HD mice fed a normal diet. The suppression of the pathogenic processes by DR in HD mice suggests that mutant huntingtin promotes neuronal degeneration by impairing cellular stress resistance, and that the body wasting in HD is driven by the neurodegenerative process. Our findings suggest a dietary intervention that may suppress the disease process and increase the life span of humans that carry the mutant huntingtin gene.

  • Dietary restriction or addition of supplementary substances such as omega-3 fatty acids or resveratrol can induce an increase in BDNF levels and reduce cognitive impairment in animal models.

    “dietary restriction (i.e., the maintenance of a balanced diet) or addition of supplementary substances (e.g., omega-3 fatty acids; resveratrol) can induce an increase in BDNF levels and reduce cognitive impairment in animal models [224–226].”

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.
