MicroRNAs are endogenous, noncoding RNAs crucial for the post-transcriptional regulation of gene expression. In this study, we investigated the role of miR-335-5p in spatial learning and synaptic plasticity. To this end we first showed spatial learning induced down-regulation of miR-335-5p. Next we found impairment in long-term memory and reduction in hippocampal long-term potentiation by exogenous administration of the miRNA. These findings demonstrate that miR-335-5p is a key coordinator of the intracellular pathways that mediate experience-dependent changes in the brain.

Abstract

MicroRNAs are endogenous, noncoding RNAs crucial for the post-transcriptional regulation of gene expression. In this study, we investigated the role of miR-335-5p in spatial learning and synaptic plasticity. To this end we first showed spatial learning induced down-regulation of miR-335-5p. Next we found impairment in long-term memory and reduction in hippocampal long-term potentiation by exogenous administration of the miRNA. These findings demonstrate that miR-335-5p is a key coordinator of the intracellular pathways that mediate experience-dependent changes in the brain.
