| Outline of Final Research Achievements |
NRSF/REST was originally reported as a transcriptional master regulator of neuronal differentiation during early neural development. However, recent report claimed that REST is key regulator of brain aging, and in human REST expression levels highly correlated with cognitive function in mild cognitive impairment (MCI) and Alzheimer’s disease (AD) patients. We explored whether REST gene expression and their potential roles in neuronal protection in the aged neurons, with special interest on REST splicing variant, named REST4. REST and REST4 expression was altered during aging of neurons, but the functional significance of the REST4 short isoform remain uncertain.
