SAMP8 Mice as a Model of Age-Related Cognition Decline with Underlying Mechanisms in Alzheimer’s Disease

Liu, Bo, Liu, Jie, Shi, Jing-Shan·2020·Journal of Alzheimer's Disease

Abstract

Alzheimer's disease (AD) is a highly age-related cognitive decline frequently attacking the elderly. Senescence-accelerated mouse-prone 8 (SAMP8) is an ideal model to study AD, displaying age-related learning and memory disorders. SAMP8 mice exhibit most features of pathogenesis of AD, including an abnormal expression of anti-aging factors, oxidative stress, inflammation, amyloid-β (Aβ) deposits, tau hyperphosphorylation, endoplasmic reticulum stress, abnormal autophagy activity, and disruption of intestinal flora. SAMP8 mice, therefore, have visualized the understanding of AD, and also provided effective ways to find new therapeutic targets. This review focused on the age-related pathogenesis in SAMP8 mice, to advance the understanding of age-related learning and memory decline and clarify the mechanisms. Furthermore, this review will provide extensive foundations for SAMP8 mice used in therapeutics for AD.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • The SAMP8 mice exhibit reduced expression and lower activity of anti-aging factors including sirtuin/Sirt, FoxOs, and Klothos.

    “The SAMP8 mice exhibit reduced expression and lower activity of anti-aging factors including silent information regulator type (sirtuin/Sirt), Forkhead box class O (FoxOs), and Klothos.”
  • The SAMP8 mouse strain is considered an excellent model for investigating Alzheimer's disease (AD).

    “On the other hand, the SAMP8 mouse strain is considered an excellent model for investigating Alzheimer’s disease (AD), a cognitive decline disorder that predominantly affects the elderly.”
  • These factors play crucial roles in the aging process.

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.
