Neurons exploit local mRNA translation and retrograde transport of transcription
factors to regulate gene expression in response to signaling events at distal
neuronal ends. Whether epigenetic factors could also be involved in such
regulation is not known. We report that the mRNA encoding the high-mobility group
N5 (HMGN5) chromatin binding protein localizes to growth cones of both
neuron-like cells and of hippocampal neurons, where it has the potential to be
translated, and that HMGN5 can be retrogradely transported into the nucleus along
neurites. Loss of HMGN5 function induces transcriptional changes and impairs
neurite outgrowth, while HMGN5 overexpression induces neurite outgrowth and
chromatin decompaction; these effects are dependent on growth cone localization
of Hmgn5 mRNA. We suggest that the localization and local translation of
transcripts coding for epigenetic factors couple the dynamic neuronal outgrowth
process with chromatin regulation in the nucleus.
