Transcriptional and epigenetic mechanisms in developing neurons

Within the nervous system, neurotrophic factors and activity regulate a wide range of processes including the proliferation of neuronal precursors, and the growth, survival, and synaptic connectivity of developing neurons. Many, if not all of the stimuli that contribute to such processes have the capacity to signal to the nucleus and influence gene expression. Our laboratory is interested in understanding the transcriptional and epigenetic mechanisms that regulate gene expression in neurons. We will use in vivo and in vitro models to address 1) the role of the transcription factor CREB in the adult and developing nervous system 2) characterize a novel signalling pathway that controls neuronal gene expression by inducing epigenetic changes 3) identify RNA transcripts locally translated in axons.
