Abstract In this short review, we highlight recent findings in the emerging field of epitranscriptomic mechanisms and discuss their potential role in neural plasticity, learning and memory. These include the influence of RNA modifications on activity-induced RNA structure states, RNA editing and RNA localization, and how qualitative state changes in RNA increase the functional diversity and information-carrying capacity of RNA molecules. We predict that RNA modifications may be just as important for synaptic plasticity and memory as quantitative changes in transcript and protein abundance, but with the added advantage of not being required to signal back to the nucleus, and therefore better suited to be coordinated with the temporal dynamics of learning.
Formatted abstract
MicroRNAs (miRNAs) are a class of endogenous, small non-coding RNAs that mediate post-transcriptional gene silencing by complementary binding to the 3′untranslated region of target mRNAs. The transient and localized expression of these small RNAs in dendrites, their capacity to respond in an activity-dependent manner, and the observation that a single miRNA can simultaneously regulate many genes, make brain-specific miRNAs ideal candidates for the fine-tuning of gene expression associated with neural plasticity and memory formation. Here we provide an overview of the current literature, which supports the proposal that non-coding RNA-mediated regulation of gene function represents an important, yet underappreciated, layer of epigenetic control that contributes to learning and memory in the adult brain.

Highlights: ► MicroRNAs are a class of small, non-coding RNAs that regulate gene function by inhibiting translation and/or facilitating degradation of target RNAs. ► A single microRNA can simultaneously regulate many genes. ► MicroRNAs may regulate neural plasticity and memory in three, distinct, but interrelated ways.
