RE-1 silencing transcription factor (REST): a regulator of neuronal development and neuronal/endocrine function

Cell Tissue Res. 2015 Jan;359(1):99-109. doi: 10.1007/s00441-014-1963-0. Epub 2014 Aug 5.


RE-1 silencing transcription factor (REST) is a transcriptional repressor that has been proposed to function as a master negative regulator of neurogenesis, as REST target genes encode neuronal receptors, ion channels, neuropeptides and synaptic proteins. During neuronal differentiation, REST expression levels are reduced, allowing expression of selected REST target genes. The analysis of neural stem/progenitor cells that are either devoid of REST or overexpress REST revealed that REST is not the master regulator that is solely responsible for the acquisition of the neuronal fate. Rather, REST provides a regulatory hub that coordinately regulates multiple tiers of neuronal development in vitro. In addition, REST may play an important role for maintaining the integrity of adult neurons. REST confers oxidative stress resistance and is essential for maintaining neuronal viability. Furthermore, the concentration of REST has been reported to influence the pathogenic outcome by neuronal diseases, including stroke, epilepsy and Alzheimer's disease. Experiments performed with PC12 pheochromocytoma cells indicate that REST may function as a key regulator of the neurosecretory phenotype. Moreover, transgenic mice overexpressing REST in pancreatic β-cells showed impaired insulin secretion leading to significantly reduced plasma insulin levels. Based on the fact that REST plays a prominent role in controlling stimulus-induced secretion in endocrine cells, we propose that REST may also be important for neurotransmitter release via regulation of genes that encode important proteins of the exocytotic machinery.
