Abstract

Brain-specific overexpression of the human RCAN1.1S isoform in mice promotes early age-dependent memory deficits and synaptic plasticity issues.

  • Increased levels of RCAN1 are found in the brains of individuals with Down syndrome and Alzheimer's disease.
  • RCAN1 expression is also elevated in the brains of normally aging humans.
  • Overexpression of RCAN1.1S in mice leads to early deficits in memory and synaptic function.
  • This overexpression is associated with tau pathology and altered activity of a protein involved in mitochondrial function.
  • Chronic RCAN1 overexpression may disrupt mitochondrial fission processes, contributing to neurodegeneration linked to Alzheimer's disease.
