It is widely believed that the brain processes information and
stores memories by modifying and stabilizing synaptic connections between neurons. In experimental models of synaptic plasticity, such as
long-term potentiation (LTP), the stabilization of changes in synaptic
strength requires rapid de novo RNA and protein
synthesis. Candidate genes, which could underlie activity-dependent
plasticity, have been identified on the basis of their rapid induction
in brain neurons. Immediate-early genes (IEGs) are induced in
hippocampal neurons by high-frequency electrical stimulation that
induces LTP and by behavioral training that results in long-term memory (LTM) formation. Here, we investigated the role of the IEG
Arc (also termed Arg3.1) in hippocampal plasticity. Arc
protein is known to be enriched in dendrites of hippocampal neurons
where it associates with cytoskeletal proteins (Lyford et al., 1995). Arc is also notable in that its mRNA and protein
accumulate in dendrites at sites of recent synaptic activity (Steward
et al., 1998). We used intrahippocampal infusions of antisense
oligodeoxynucleotides to inhibit Arc protein expression and examined
the effect of this treatment on both LTP and spatial learning. Our
studies show that disruption of Arc protein expression impairs the
maintenance phase of LTP without affecting its induction and impairs
consolidation of LTM for spatial water task training without affecting
task acquisition or short-term memory. Thus, Arc appears
to play a fundamental role in the stabilization of activity-dependent
hippocampal plasticity.

potentiation; long-term memory; hippocampus; oligodeoxynucleotide; immediate-early; gene; spatial memory
