Multiple hippocampal processes and cognitive functions change with aging or Alzheimer's disease, but the potential triggers of these aging cascades are not well understood. Here, we quantified hippocampal expression profiles and behavior across the adult lifespan to identify early aging changes and changes that coincide with subsequent onset of cognitive(More)
microRNAs (miRNAs) are a class of small noncoding RNAs that posttranscriptionally regulate a large fraction of genes in animal genomes. We have previously published computational miRNA target predictions in five vertebrates, six flies, and three nematodes. Here, we report a comprehensive study of the "deep" conservation of miRNA targets and conserved 3'UTR(More)
