(Submitter supplied) Recent microarray studies in the hippocampus of rodents or Alzheimer’s disease (AD) subjects have identified a substantial number of cellular pathways/processes correlated with aging and cognitive decline. However, the temporal relationships among these expression changes or with cognitive impairment have not been studied in depth. Here, using Affymetrix microarrays, immunohistochemistry and Morris water maze cognitive testing across 5 age groups of male F344 rats (n=9-15/group, one microarray per animal), we systematically analyzed the temporal sequence and cellular localization of aging changes in expression. more...

Analysis of hippocampi from F344 males, at 5 age points across the adult lifespan, tested on the Morris water maze (MWM) task. MWM is a dorsal hippocampal-dependent, spatial memory task. MWM performance showed an age effect. Results provide insight into the molecular basis of cognitive aging.
