Signalling: An oncogene becomes RESTless

Gemma K. Alderton

REST (repressor-element-1 silencing transcription factor) is a transcriptional repressor that is associated with the maintainenance of neuron stem cell self-renewal and has been characterized as an oncogene in neuronal stem cells and, paradoxically, as a tumour suppressor in epithelial tissues. How REST accomplishes these activities and how it is incorporated into cell signalling pathways is unclear.
